Монтаж дождеприемников: Дождеприемники для ливневой канализации этапы монтажа видео

Установка дождеприемников для ливневой канализации своими руками

Распределительные колодцы или, как еще их называют – дождеприемники, это один из основных элементов в структуре ливневой канализации. На данный элемент приходится главная работа, так как именно здесь скапливается дождевая или талая вода, далее по ним она уходит за границы участка или в сливную яму. Подобная конструкции предупреждает скопление луж на придомовой территории и защищает строение, так как талая вода негативно сказывается на крепости стен и фундамента.

По своей структуре система для отвода может различаться. Если смотреть на материал изготовления, то зачастую это пластик или чугун. Лучше всего останавливать свой выбор на той конструкции, которая изготовлена с выполнением всех требований ГОСТа, иначе качество водоотведения может оказаться не на том уровне, на котором вы ожидали. При расчете бюджета на установку лучше взять материал самого хорошего качества, а сэкономить на монтажных работах, так как установка колодца – процесс не очень сложный и его можно выполнить самостоятельно. В этой статье мы и хотим осветить данный процесс, раскрыть все детали установки дождеприемника в ливневке.

Подготовка к выполнению работ

Перед началом работ необходимо определить, где именно будут располагаться дождеприемники. Вариантов их расположения несколько:

1. Установка под стоками, если на стенах дома установлены стоки с крыши, то их обязательно дополняют стоковыми колодцами. Такая система отведет лишнюю воду от фундамента, то есть снизит разрушительное влияние сточных вод на строение.
2. Вдоль дорожек. Во время создания проекта благоустройства придомовой территории советуется монтаж дождеприемников вдоль дорожек. Распределительный колодец устанавливают в углублении, а сами дорожки делают под небольшим углом, это предотвратит застой воды.
3. В тех местах, где постоянно скапливается вода. На каждом участке есть такие зоны, где постоянно скапливается дождевая и талая вода. Чтобы отводить ее, следует установить в этих местах колодцы, в таком случае следует установить точки сбора здесь, чтобы во время осадков все сразу уходило в отводящую систему. Сложность здесь состоит только в выборе места установки и согласовании его с общим проектом.

Следующая важная вещь, от которой зависит весь процесс – габариты и форма отводящего элемента. Если колодец имеет небольшой размер и круглую форму, то установить его просто, конструкции большего размера потребуют повозиться с ними. Теперь рассмотрим более внимательно процедуру установки.

Процесс установки дождеприемника

Неправильная процедура установки дождеприемника может привести к возникновению целого ряда неприятных ситуаций в будущем. Например, случается, что отводящие элементы забиваются, а возможности для их очистки нет, так как это изначально не было предусмотрено проектом. Для корректной работы конструкции следует соблюдать два важных требования: создать прочную основу и хорошо закрепить колодец снизу. Рекомендации, как установить дождеприемники шаг за шагом, читайте ниже:

1. Проведите подготовительные работы для создания котлована. Рассчитайте его размеры, при этом соизмеряйте их с размерами колодца. Можно провести замеры или ознакомиться с технической документацией, где указывают эти данные. К полученным цифрам добавьте 3 см – это и будет необходимый диаметр ямы, к глубине прибавляют 30-35 см. Вот каких размеров должен быть котлован.
2. В готовой яме создается подушка из песка, на дно высыпается его слой, заливается жидкостью и хорошенько трамбуется.
3. Далее необходимо подключить распределительный колодец к трубам канализации для сточных вод, по которым будет уходить вся жидкость с участка. Важно – приемник и трубы располагаются по высоте ровно, с той точность, которую позволяют условия монтажа. Если будет разница между высотой элементов, возникнут проблемы при их соединении и в работе.
4. На дно котлована льют бетонную смесь. Ее не нужно лить в большом количестве, хватит небольшого слоя. На слой бетона устанавливаем колодец, фиксируем его, чтобы не шатался.
5. После надежной фиксации дождеприемника проводим дополнительное его крепление при помощи бетона. Заливается раствор с боков, для этого мы и оставляли 3 см по окружности. Такая чаша станет надежной основой для колодца.
6. Теперь устанавливаем все составляющие системы, обычно в этот список входят перегородки и корзина.

Как видите, процесс установки не отличается сложностью, необходимо только учитывать все важные детали. В этот перечень входит и выбор точки установки, и создание надежной подложки и крепление колодца в яме. При правильном выполнении всех работ, можно рассчитывать на адекватную и надежную работу ливневки на протяжении нескольких лет.

90000 Hydraulic Design Manual: Storm Drain Inlets 90001 Anchor: # i1015513 90002 Section 5: Storm Drain Inlets 90003 Anchor: # i1015518 90004 Inlet Types 90005 90006 Inlets used for the drainage of highway surfaces into four major classes: 90007 Anchor: #HEKKKKHG 90004 Curb Opening Inlets 90005 90006 Figure 10-2 illustrates a generic example of a typical curb opening inlet.Curb inlets are used in urban sections of roadway along the curb line. 90007 90006 Anchor: # i1001607grtop 90007 90006 Figure 10-5. Curb Opening Inlet 90007 90006 Most curb opening inlets depend heavily upon an adjacent depression in the gutter for effective flow interception (see Figure 10-3).Greater interception rates result in shorter (and probably, more economical) inlet lengths. However, a large gutter depression can be unsafe for traffic flow and bicycle operation near the gutter line. Therefore, a compromise is in order when selecting an appropriate value for the gutter depression. The depth of the gutter depression should be: 90007 90018 Anchor: #OGDEAIRW 90019 0 to 1 in.(0 to 25 mm) where the gutter is within the traffic lane 90020 Anchor: #YGLCRQEP 90019 1 to 3 in. (25 to 75 mm) where the gutter is outside the traffic lane or in the parking lane 90020 Anchor: #NYBCPINR 90019 1 to 5 in. (25 to 125 mm) for lightly traveled city streets that are not on a highway route.90020 90025 90006 Anchor: # i1001609grtop 90007 90006 Figure 10-6. Curb Opening Inlet Depression 90007 90006 Some municipalities in the state prefer to recess curb inlets with significant depression to minimize interference with traffic flow.The inlet is recessed from the line of the curb and gutter such that the depression does not extend beyond the gutter line. This may improve driveability; however, the curb transition may pose a hazard to traffic. 90007 90006 Curb opening inlets are useful in sag and on-grade situations because of their self-cleansing abilities and hydraulic efficiency.Additionally, they are often preferred over grate inlets because the inlet is placed outside the travel way and poses less of a risk to motorists and bicycle traffic. 90007 90006 A drawback of curb opening inlets is that the flowline of the opening is fixed and not readily adaptable to changing pavement levels as occur in surface treatment overlays.Successive overlays can gradually reduce or even eliminate the original opening available for water removal, unless the pavement edge is tapered to the original gutter line. 90007 Anchor: #YBRJUDCJ 90004 Grate Inlets 90005 90006 Figure 10-4 illustrates a typical grate inlet. Water falls into the inlet through a grate instead of an opening in the curb.Designers use many variations of this inlet type, and the format of the grate itself varies widely as each foundry may have its own series of standard fabrication molds. 90007 90006 Anchor: #ALXUMWEDgrtop 90007 90006 Figure 10-7. Grate Inlet Schematic 90007 90006 For the most part, grate inlets are used in sag configurations in gutters, adjacent to concrete traffic barriers or rails (where curb inlets would not be practicable), V-shaped gutters with no curb or barrier, and ditches.Grate inlets may also be used at on-grade situations combined with curb inlets. 90007 90006 Grate inlets adapt to urban roadway features such as driveways, street intersections, and medians. When grate inlets are specified, the grate configuration and orientation should be compatible with bicycle and wheelchair safety.90007 90006 Access to the storm drain system through a grate inlet is excellent in that, usually, the grate is removable. On the other hand, maintenance of grate inlets can be a continuing problem during the life of the facility; the propensity to collect debris makes grate inlets a constant object of maintenance attention.As such debris accumulates it obstructs the flow of surface water into the inlet. Grate inlets also present potential interference with bicycles and wheelchairs. 90007 Anchor: #REIIILLF 90004 Linear Drains 90005 90006 Linear drains were designed for the interception of wide spread, low flow situations.Applications include intercepting sheet flow from the roadway when collection at a concentration point is not practical, or providing a generalized inlet for stagnate flow on pavements without slope. Linear drains have the advantage that no depression is necessary for hydraulic efficiency. 90007 90006 Linear drains may be useful in problematic areas where curb and grate inlets are ineffective, such as along a median barrier, and at super elevation transitions.Linear drains can also be installed transversely across the roadway. 90007 90006 However, linear drains have several drawbacks: 90007 90018 Anchor: #VNGNKVOP 90019 Linear drains have a high propensity to collect debris in sag configurations. Regular maintenance is required to clear debris from over the drain inlet.90020 Anchor: #ORTNQESH 90019 Installation can be difficult. Because the inlet is installed flush with the surface of the pavement, placement is critical. 90020 90025 Anchor: # i1015653 90004 Slotted Drains 90005 90006 Slotted drains consist of a corrugated pipe with an extended slot, or throat, at the top (see Figure 10-5).The throat of a slotted drain inlet is ordinarily reinforced for structural integrity. 90007 90006 Anchor: # i1001689grtop 90007 90006 Figure 10-8. Slotted Drain Inlet 90007 90006 Slotted drains should be installed with sufficient slope to provide a cleaning velocity for the corrugations.If not, regular cleaning and maintenance must be scheduled on the slotted drain. Clean out access boxes are usually needed at the far end of each slotted drain run to facilitate regular maintenance and cleaning. 90007 Anchor: # i1180801 90004 Trench Drains 90005 90006 Trench drains may be precast or cast-in-place. Figure 10-6 illustrates the body and grate of an installed precast trench drain.90007 90006 Anchor: #AFAODWXWgrtop 90007 90006 Figure 10-9. Precast trench drain. 90007 90006 Trench drains have the advantage of a shallower embedment depth and an extremely smooth invert that does not retain sediments, but the disadvantage of having a limited volume because of their size.90007 90006 Trench drains on Department roadways are required to have non-removable grates because removable grates may come loose or move which will create a traffic hazard. The grates specified by the Department have a minimum of 60% open space which allows for cleaning with a vacuum truck or water truck without removing the grates.90007 Anchor: # i1015765 90004 Combination Inlets 90005 90006 Combination inlets such as curb and grate can be useful in many configurations, especially sag locations. Because of the inherent debris problem in sags, the combination inlet offers an overflow drain if part of the inlet becomes completely or severely clogged by debris.Maintenance of combination inlets is usually facilitated by the fact that the grate is removable, providing easy access to the inlet and associated storm drain system. 90007 90006 Combination inlets used on-grade generally are not cost-effective because of the relatively small additional hydraulic capacity afforded.Authentic data on such combinations are insufficient to establish accurate factors for determining the true capacity of a combination inlet. 90007 90006 For a combination curb and grate, assume that the capacity of the combination inlet comprises the sum of the capacity of the grate and the upstream curb opening length.Ignore the capacity of the curb opening that is adjacent to the grate opening. 90007 Anchor: # i1015785 90004 Inlets in Sag Configurations 90005 90006 An inlet in a sag configuration is considered the «end of the line «because the water and its debris load have no other place to go. Because of this, failure of an inlet in a sag configuration often represents a threat to the successful operation of a storm drain system.Therefore, the hydraulic designer must consider some additional items such as complex ponded width and complex approach slopes. 90007 90006 In a sag configuration, the controlling ponded width can be from one of two origins. The inlet itself may cause a head that translates to a ponded width, and the flow in the curb and gutter from each direction subtends its own ponded width.90007 90006 If the sag is in a vertical curve, the slope at the sag is zero, which would mean that there is no gutter capacity. In reality there is a three-dimensional flow pattern resulting from the drawdown effect of the inlet. As an approximation, one reasonable approach is to assume a longitudinal slope of one half of the tangent grade.90007 90006 Because the water or its debris load can go no other place, an appropriate safety factor should be applied to the inlet size. For grate inlets in sags, the usual safety factor is approximately two; for curb inlets, the factor can be somewhat less. In application, the factor of safety for a grate inlet is applied as a safety reduction factor, or clogging factor.For example, a safety factor of 2 would result in a clogging factor of 50%, which assumes that half the grate is clogged by debris. 90007 90006 Where significant ponding can occur such as in an underpass and in a sag-vertical curve, good engineering practice is to place flanking inlets on each side of the sag location inlet to relieve some or most of the flow burden on the inlet in sag.Flanking inlets should be analyzed as inlets on-grade at some specified distance (Usually 50 or 100 feet) away from the low point on the sag vertical curve. 90007 Anchor: # i1015809 90004 Median / Ditch Drains 90005 90006 Drains or inlets appearing in ditches and medians are usually grate inlets and are also termed «drop inlets.»The operation of the inlet is enhanced by a concrete riprap collar that forms a type of bowl around the inlet. 90007 90006 Often, such an inlet is in a sag (sump) configuration created by a ditch block. Department research ( 0-5823-1) indicates that a six inch ditch block may not be adequate to ensure complete capture of flow; a taller ditch block may be necessary.However, the designer must either determine the required depth for complete capture, or account for flow over the ditch block to the next inlet. Care must be taken to ensure that the ditch block slopes meet clear zone standards. 90007 90006 Anchor: # i1001805grtop 90007 90006 Figure 10-10.Median / Ditch Inlet 90007 Anchor: #JXVONAUM 90004 Drainage Chutes 90005 90006 Drainage chutes, also referred to as over-side drains or curb slots, are commonly used at the ends of bridges to either prevent flow from running onto a bridge deck, or to prevent flow from running off a bridge deck onto the pavement. There may be other locations where a drainage chute or curb cut may be useful in removing flow from the pavement where no storm drainage system is present and where suitable outfall is present behind the curb and gutter section.In most cases, an opening in the curb connects to a scour-resistant channel or chute which prevents erosion of the embankment or slope. In some instances, the channel or chute may be replaced with a pipe placed in the roadway embankment as illustrated in Figure 10-8. This treatment facilitates mowing and other maintenance but also introduces its own maintenance needs to keep it from clogging.90007 90006 Anchor: #VDTMTKOTgrtop 90007 90006 Figure 10-11. Over-Side Drains 90007 Anchor: # i1015846 90004 Inlet Locations 90005 90006 The inlet location may be dictated either by roadway elements, hydraulic requirements, or both. Inlets should be placed upstream of roadway elements such as sags, street intersections, gore islands (See Figure 10-9), super elevation transitions, driveways, cross-walks, and curb ramps (see Bypass Flow Design Approach).Flow across intersections, ramps, and to a lesser extent, driveways, may cause a traffic hazard, while flow across cross-walks and curb ramps may cause a pedestrian hazard. Inlets at these locations should be designed to capture 100% of the flow. Inlets should also be located hydraulically to prevent excessive gutter flow and excessive ponding. 90007 90006 Anchor: # i1003413grtop 90007 90006 Figure 10-12.Inlet at a Gore Island 90007 .90000 Storm Water Management Model (SWMM) | Water Research 90001 90002 90003 Helps predict runoff quantity and quality from drainage systems 90004 90005 90002 On this Page 90005 90008 90009 90008 EPA’s Storm Water Management Model (SWMM) is used throughout the world for planning, analysis, and design related to stormwater runoff, combined and sanitary sewers, and other drainage systems. It can be used to evaluate gray infrastructure stormwater control strategies, such as pipes and storm drains, and is a useful tool for creating cost-effective green / gray hybrid stormwater control solutions.SWMM was developed to help support local, state, and national stormwater management objectives to reduce runoff through infiltration and retention, and help to reduce discharges that cause impairment of waterbodies. 90009 90012 Software, Compatibility, Manuals, and Other Documents 90013 90008 SWMM is a Windows-based desktop program. It is open source public software and is free for use worldwide. SWMM 5 was produced in a joint development effort with CDM, Inc., a global consulting, engineering, construction, and operations firm.90009 90016 Software 90017 90016 Source Codes and Bug Fixes 90017 90016 Manuals and Guides 90017 90016 Other Documents 90017 90008 90003 Disclaimer: Any mention of trade names, manufacturers, or products does not imply an endorsement by EPA. EPA and its employees do not endorse any commercial products, services, or enterprises. 90004 90009 90008 Top of Page 90009 90012 Capabilities 90013 90008 SWMM is used for single event or long-term simulations of water runoff quantity and quality in primarily urban areas-although there are also many applications that can be used for drainage systems in non-urban areas.SWMM provides an integrated environment for editing study area input data, running hydrologic, hydraulic and water quality simulations, and viewing the results in a variety of formats. These include color-coded drainage area and conveyance system maps, time series graphs and tables, profile plots, and statistical frequency analyses. 90009 90008 90035 ►Hydraulic Modeling: 90036 SWMM contains a flexible set of hydraulic modeling capabilities used to route runoff and external inflows through the drainage system network of pipes, channels, storage / treatment units and diversion structures.These include the ability to do the following: 90009 90038 90039 Handle drainage networks of unlimited size. 90040 90039 Use a wide variety of standard closed and open conduit shapes as well as natural channels. 90040 90039 Model special elements, such as storage / treatment units, flow dividers, pumps, weirs, and orifices. 90040 90039 Apply external flows and water quality inputs from surface runoff, groundwater interflow, rainfall-dependent infiltration / inflow, dry weather sanitary flow, and user-defined inflows.90040 90039 Utilize either kinematic wave or full dynamic wave flow routing methods. 90040 90039 Model various flow regimes, such as backwater, surcharging, reverse flow, and surface ponding. apply user-defined dynamic control rules to simulate the operation of pumps, orifice openings, and weir crest levels. 90040 90039 Percolation of infiltrated water into groundwater layers. 90040 90039 Interflow between groundwater and the drainage system. 90040 90039 Nonlinear reservoir routing of overland flow.Runoff reduction via LID controls. 90040 90057 90008 90035 ►Accounting for Hydrologic Processes. 90036 SWMM accounts for various hydrologic processes that produce runoff from urban areas, which include the following: 90009 90038 90039 Runoff reduction via green infrastructure practices. 90040 90039 Time-varying rainfall (precipitation) and evaporation of standing surface water. 90040 90039 Snow accumulation and melting. 90040 90039 Rainfall interception from depression storage.90040 90039 Infiltration of rainfall into unsaturated soil layers. 90040 90039 Percolation of infiltrated water into groundwater layers Interflow between groundwater and the drainage system. 90040 90039 Nonlinear reservoir routing of overland flow. 90040 90057 90008 Spatial variability in all of these processes is achieved by dividing a study area into a collection of smaller, homogeneous sub-catchment areas. Each of the areas contains its own fraction of pervious and impervious sub-areas.Overland flow can be routed between sub-areas, between sub-catchments, or between entry points of a drainage system. 90009 90008 90035 ►Pollutant Load Estimation: 90036 SWMM can estimate the production of pollutant loads associated with stormwater runoff. The following processes can be modeled for any number of user-defined water quality constituents: 90009 90038 90039 Dry-weather pollutant buildup over different land uses. 90040 90039 Pollutant wash-off from specific land uses during storm events.90040 90039 Direct contribution of rainfall deposition. Reduction in dry-weather buildup due to street cleaning. 90040 90039 Reduction in wash-off load due to best management practices (BMPs). 90040 90039 Entry of dry weather sanitary flows and user-specified external inflows at any point in the drainage system. 90040 90039 Routing of water quality constituents through the drainage system. 90040 90039 Reduction in constituent concentration through treatment in storage units or by natural processes in pipes and channels.90040 90057 90008 90035 ►Add-in Tool for Climate Projections: 90036 SWMM includes a software utility that allows future climate change projections to be incorporated into modeling. The 90003 SWMM Climate Adjustment Tool (SWMM-CAT) 90004 provides a set of location-specific adjustments derived from World Climate Research Programme global climate change models. SWMM-CAT accepts monthly adjustment factors for climate-related variables that could represent the potential impact of future climate changes.90009 90008 Top of Page 90009 90012 Applications 90013 90008 Typical applications of SWMM: 90009 90038 90039 Designing and sizing of drainage system components for flood control. 90040 90039 Sizing detention facilities and their appurtenances for flood control and water quality protection. 90040 90039 Mapping flood plains of natural channel systems- 90003 SWMM 5 is a FEMA-approved model for National Flood Insurance Program studies. 90004 90040 90039 Designing control strategies for minimizing combined sewer overflows.90040 90039 Evaluating the impact of inflow and infiltration on sanitary sewer overflows. 90040 90039 Generating nonpoint source pollutant loadings for waste load allocation. 90040 90039 Controlling site runoff using green infrastructure practices as low LID controls. 90040 90039 Evaluating the effectiveness of best management practices and low impact development for reducing wet weather pollutant loadings. 90040 90057 90008 Top of Page 90009 90012 Green Infrastructure as LID Controls 90013 90008 SWMM allows engineers and planners to represent combinations of green infrastructure practices as low impact development (LID) controls to determine their effectiveness in managing runoff.Although some of these practices can also provide significant pollutant reduction benefits, at this time, SWMM only models the reduction in runoff mass load resulting from the reduction in runoff flow volume. SWMM can explicitly model eight different generic green infrastructure practices: 90009 90008 90035 Rain Gardens. 90036 A depressed area, planted with grasses, flowers, and other plants, that collects rain water from a roof, driveway, or street and allows it to infiltrate into the ground.More complex rain gardens are often referred to as bioretention cells. 90009 90008 90143 90009 90008 90143 90009 90008 90035 Bioretention Cells (or Bioswales). 90036 Depressions containing vegetation grown in an engineered soil mixture placed above a gravel drainage bed that provide storage, infiltration, and evaporation of both direct rainfall and runoff captured from surrounding areas. 90009 90008 90143 90009 90008 90143 90009 90008 90035 Vegetative Swales. 90036 Channels or depressed areas with sloping sides covered with grass and other vegetation.They slow down the conveyance of collected runoff and allow it more time to infiltrate the native soil beneath it. 90009 90008 90143 90009 90008 90143 90009 90008 90035 Infiltration Trenches. 90036 Narrow ditches filled with gravel that intercept runoff from upslope impervious areas. They provide storage volume and additional time for captured runoff to infiltrate the native soil below. 90009 90008 90143 90009 90008 90143 90009 90008 90035 Green Roofs. 90036 A variation of a bioretention cell, green roofs have a soil layer laying atop a special drainage mat material that conveys excess percolated rainfall off of the roof.They contain vegetation that enable rainfall infiltration and evapotranspiration of stored water. 90009 90008 90143 90009 90008 90143 90009 90008 90035 Rooftop (Downspout) Disconnection. 90036 This practice allows rooftop rainwater to discharge to pervious landscaped areas and lawns instead of directly into storm drains. It can be used to store stormwater and / or allow stormwater to infiltrate into the soil. 90009 90008 90143 90009 90008 90143 90009 90008 90035 Rain Barrels 90036 90035 or 90036 90035 Cisterns (Rainwater Harvesting).90036 Containers that collect roof runoff during storm events and can either release or re-use the rainwater during dry periods. Cisterns may be located above or below ground and have a greater storage capacity than a rain barrel. 90009 90008 90143 90009 90008 90143 90009 90008 90035 Continuous Permeable Pavement 90036 90035 Systems. 90036 Excavated areas that allow rainfall to immediately pass through the pavement into the gravel storage layer below where it can infiltrate at natural rates into the site’s native soil.In block paver systems, rainfall is captured in the open spaces between the blocks and conveyed to the storage zone and native soil below. 90009 90008 Top of Page 90009 90012 Technical Support 90013 90038 90039 90035 Technical Contact: 90036 For comments or questions, contact us about SWMM. 90040 90039 90035 Listserv: 90036 A SWMM users ‘listserv was established by the University of Guelph.
