Description

Lateral water supply rainwater infiltration system

Technical Field

The utility model relates to a rainwater processing technology field, more specifically say, relate to a side direction feedwater rainwater infiltration system.

Background

In urban construction, the impervious ground is increased year by year, the runoff of rainwater is also continuously increased, and when strong precipitation or continuous precipitation occurs, the water drainage capability of partial areas is insufficient, so that urban waterlogging is easily caused. At present, sponge urban construction engineering with low influence is developed aiming at urban inland inundation areas which are easy to generate road surface ponding in heavy rainfall seasons, rainfall infiltration channels and infiltration capacity are increased, runoff total amount is effectively reduced, and urban flood disasters are reduced. The side direction feedwater rainwater cistern can use sponge city construction, plays the cushioning effect to rainfall runoff, can alleviate the flood calamity that the torrential rain causes.

SUMMERY OF THE UTILITY MODEL

The technical idea of the utility model is to filter the rainwater and then dredge to the sand layer of shallow and deep portion, supply groundwater resource plays the cushioning effect to rainfall runoff, can alleviate the flood disasters that the torrential rain causes.

For solving the technical problem, the utility model discloses the technical scheme who adopts does:

a lateral water supply rainwater infiltration system comprises a filter tank, a reservoir and an infiltration well, wherein the filter tank comprises a cover plate, a filter screen, a water inlet pipe, gravels, a water outlet filter screen and a water outlet; the water storage tank comprises soil covering, a filter screen and coarse sand; the infiltration well comprises a well cover and a well; the water storage tank is a pit with a rectangular cross section excavated on the ground, and the filtering tank is also a pit with a rectangular cross section excavated on the ground; the filtering tank is arranged on one side of the water storage tank.

And further, the bottom of the reservoir enters a shallow sandy soil layer by about 50 cm.

Furthermore, coarse sand with the thickness of about 1m is filled at the bottom of the reservoir, a layer of filter screen is covered on the coarse sand to prevent the covering soil from permeating into the coarse sand, the filter screen is covered with the covering soil, and the covering soil is flush with the natural ground surface.

Further, the infiltration well is arranged inside the reservoir and goes deep into the deep sand layer, and the well cover is arranged at the well mouth and is parallel and level to the ground surface.

Furthermore, gravels are filled in the lower part of the filtering tank, a filtering screen covers the gravels, a filtering tank cover plate is arranged at the top of the filtering tank, an overhauling space is reserved between the filtering screen and the filtering tank cover plate, and the filtering tank is provided with a water inlet and a water outlet; the water inlet of the filter tank is connected with the overflow port of the city rainwater pipeline; the filtering ponds apopore intercommunication cistern, a plurality of is located to the filtering ponds apopore, the filtering ponds apopore is equipped with the apopore filter screen.

Furthermore, the height of the gravel in the filtering tank is higher than that of the coarse sand in the water storage tank; the height of the water outlet hole of the filter tank is not higher than that of coarse sand in the water storage tank.

Rainwater at the overflow port of the urban rainwater pipeline enters the filtering tank through the water inlet, enters a coarse sand layer in the water storage tank through the water outlet after being filtered, and the rainwater in the water storage tank permeates a shallow sand layer and enters a deep sand layer through the infiltration well.

The utility model discloses a system is infiltrated in side direction feedwater rainwater filters through the filtering ponds, gets into the cistern with filterable rainwater side direction, and the rainwater infiltrates shallow sand soil layer, infiltrates deep sand soil layer with the rainwater through going into the infiltration well simultaneously, the utility model discloses simple structure, construction convenience, convenient to popularize and use.

Detailed Description

The following discusses in detail the embodiments of the present invention with reference to the accompanying drawings.

As shown in figures 1-3, for the embodiment of the present invention, a lateral rainwater infiltration system comprises a filtering tank 8, a reservoir 1 and an infiltration well 7.

Firstly, excavating a pit with a rectangular section, and enabling the bottom of the pit to enter a shallow sand layer by about 50 cm.

Then, the construction of the filter tank 8 is carried out at one end of the pit, the material of the filter tank can be selected from concrete, a water inlet 11 is reserved on the side wall of the upper part of the filter tank 8, a water outlet hole 13 is reserved on one side of the lower part of the filter tank 8, which is close to the reservoir, the diameter of the water outlet hole 13 is about 5cm, the density of the water outlet hole 13 is determined by the designed water discharge amount, and the arrangement height of the water outlet hole 13 is the same as that of the coarse sand 3 in the reservoir 1.

A water outlet filter screen 14 is arranged in the filter tank close to the water outlet hole 13, gravel 12 is filled into the lower part of the filter tank 8, the thickness of the gravel is larger than that of coarse sand 3 in the reservoir 1, a filter screen 10 covers the gravel 12, and a cover plate 9 is laid. Coarse sand 3 with the thickness of about 1m is filled at the bottom of the reservoir 1, a layer of filter screen 4 is covered on the coarse sand 3 to prevent the covering soil from permeating into the coarse sand 3, the filter screen is covered with the covering soil 2, and the covering soil 2 is flush with the natural ground surface.

Go into infiltration well 7 construction at last, can set up a plurality of infiltration well 7 as required in the cistern 1, go into infiltration well 7 and go deep sandy soil layer, the wall of a well 5 that is located in the cistern that the rainwater can pierce into the infiltration well gets into infiltration well 7, gets into deep sandy soil layer through going into infiltration well 7, goes into infiltration well 7 and is equipped with the well lid with the earth's surface parallel and level.

Having shown and described the basic principles, essential features, etc., of the present invention, it will be understood by those skilled in the art that various changes, modifications, substitutions, variations, etc. can be made without departing from the principles and spirit of the invention, and are intended to be included within the scope of the invention.
