Description

A kind of rain water drainage collecting pit

Technical field

Rain water drainage apparatus field is the utility model is related to, more particularly to a kind of rain water drainage collecting pit.

Background technology

China's water scarcity, in the cities more than multiple prefecture-level cities in the whole nation, more than half urban water shortage or serious water shortage, And into increasing trend.Rainwater is a kind of good freshwater resources of nature, can be achieved to flush the toilet through simple process, road surface spraying, The function of greening irrigation, reuse rainwater have significant water-saving efficiency.At the same time, healthy residence, ecology cabaret are just swift and violent Development, building area rainwater recycle are utilized system, the present situation in city have been adapted to its good water-saving benefit and environmental ecological benefit It is the important directions that modern water resource utilizes with demand.

Initial rainwater is more serious due to polluting, and is not suitable for reuse, it is necessary to which abandoned stream, later stage rainwater are suitable for since water quality is preferable Early-stage rainwater stream abandoning can effectively be realized by being back to road sprinkling or green land irrigation, the present invention, and by later stage rainwater storage reuse, Suitable for buildings such as residential quarters, factory, square, greenery patches, parks.

At present, the Chinese patent of Publication No. CN103498507B discloses a kind of rainwater flow-discarding device, it includes rainwater Well and the drainage tank and collecting pit being connected with the catch-basin, the catch-basin are joined by the first pipeline and rainwater-collecting pipe network It is logical, for connect the collecting pit and the setting height(from bottom) of the second pipe of the catch-basin be higher than be used to connecting the drainage tank and 3rd pipeline of the catch-basin, and water pump and the timer of water pump electrical connection are provided with the drainage tank, it is described The rain stop sensor with timer electrical connection is additionally provided with drainage tank..

Although this rainwater flow-discarding device realizes rain by drainage tank and the difference of the inlet channel setting height(from bottom) of collecting pit The automatic flow abandoning of water, using stop rain sensor and timer realize rain stop 24 it is small when interior appearance again rain fall when, do not abandon The function of stream, so that rainwater-collecting efficiency is improved, but this rainwater flow-discarding device is integrally complex, construction is provided with certain Difficulty.

Utility model content

The purpose of this utility model is to provide a kind of rain water drainage collecting pit, it is more dirty with that can exclude Rainwater Initial The rainwater of dirt, and later stage clean rainwater is collected, while unitary construction is relatively simple, builds the advantages of more convenient.

The above-mentioned technical purpose of the utility model technical scheme is that：

A kind of rain water drainage collecting pit, including closed rainwater collection pool located underground, the closed rainwater-collecting Pond is separated using partition wall is divided into abandoned stream setting pot and storage pond, and the abandoned stream setting pot is equipped with rainwater water inlet pipe, the abandoned stream Setting pot is equipped with barricade close to rainwater water inlet pipe one end, and the barricade is less than rainwater perpendicular to water (flow) direction, the barricade bottom Water inlet pipe elevation of bottom, the barricade top are higher than rainwater water inlet pipe top, and the abandoned stream setting pot is located at barricade and water inlet pipe Between partition wall be equipped with overflow wall, the absolute altitude at the top of the overflow wall is equal to the elevation of bottom of rainwater water inlet pipe.

By using above-mentioned technical proposal, entered after rainfall formation rainwash by rainwater water inlet pipe underground closed Rainwater collection pool, since rainwater water inlet pipe is connected with the abandoned stream setting pot in closed rainwater collection pool, and depositing due to barricade It will be stored in abandoned stream setting pot in the initial rainwater that rainwater water inlet pipe enters in advance, after abandoned stream setting pot is collected completely, after Phase rainwater enters storage pond this lattice automatically by overflow wall overflow, and can be effective by the design of abandoned stream sand setting pool volume Initial rainwater collecting effect is controlled, storage pond starts water storage after abandoned stream setting pot stores full water, effectively collects more clean Rainwater.

Further set：Waterproof coating layer is coated with the closed rainwater collection pool inner wall.

By using above-mentioned technical proposal, waterproof coating layer can effectively reduce what is collected in closed rainwater collection pool Situations such as rainwater leaks, is effectively ensured reservoir storage.

Further set：The planar grille for filtering is equipped with the rainwater water inlet pipe.

By using above-mentioned technical proposal, planar grille intercepts and filters out larger suspended matter such as shredded paper, cloth etc., rainwater Entered after the filtering of planar grille in abandoned stream setting pot.

Further set：One end of the abandoned stream setting pot and storage pond is equipped with catch pit, the pond of the catch pit side Wall is equipped with wall-through hole.

By using above-mentioned technical proposal, catch pit is set to reduce the dead volume of abandoned stream setting pot and storage pond, rain Open up wall-through hole on the wall of water abandoned stream collecting pit side, hole site through walls is higher than rainwater water inlet pipe tube top 300mm, and aperture can be according to According to needing to open up, it is mainly used for installing corresponding water pipe and electric wire etc..

Further set：It is equipped with dredge pump in the catch pit, is opened on the abandoned stream collecting pit head cover above the dredge pump Equipped with lower manhole.

By using above-mentioned technical proposal, dredge pump and rainwater reuse pump, dredge pump can be installed in the catch pit being equipped with Outlet pipe, electric wire drawn by wall-through hole, for after rain in catch pit rainwater carry out effectively exclude or shift.

Further set：The stormwater overflow pipe for leading to outside is additionally provided with the storage pond pool wall.

By using above-mentioned technical proposal, after storage pond stores completely, excessive rainwater is discharged automatically by overflow pipe, and rainwater overflows Flow tube caliber, tube bottom absolute altitude are equal to rainwater water inlet pipe caliber, tube bottom absolute altitude.

In conclusion the utility model has the advantages that：By equipped with barricade and overflow wall can be not Consume it is effective in the case of the energy remove initial rainwater, and later stage more clean rainwater is stored, simultaneously because abandoned stream sand setting In the case that pond entirety size is certain, stablize relatively for the reception amount of initial rainwater, so as to be opened automatically after reaching a certain amount of Begin to carry out water storage, effectively improve collection efficiency.
