Abstract

The utility model provides a road rain underground recharge device, which belongs to the field of drainage engineering and relates to urban road drainage, in particular to a structure for recharging and supplementing underground water by collecting and using road rain. The recharge device is composed of a rain port, a communicating pipe and a recharge well. The rain port is connected with the recharge well through the communicating pipe, and the rain port is provided with two discharging ports. One of the two discharging ports is connected with the communicating pipe, and the other discharging port is connected with an overflowing pipe. The overflowing pipe is higher than the communicating pipe, and basically rain in an early rainfall period all falls to the recharge well through the communicating pipe. The rain flows into a filter layer through a permeable pipe after flowing into the recharge well. The filter layer forms a water accumulating layer, and the rain is stored in the filter layer to leak into soil slowly to obtain underground recharge of the rain. Due to a fact that the underground recharge is conducted with the rain collected by a road rain port, effects of water source conservation and ecological environment protection are achieved, and rain pipeline burden can be reduced.

Description

The underground backflow device of road rain water

Technical field

The utility model relates to the underground backflow device of a kind of road rain water, belongs to the drainage works field, relates to urban road drainage, and the structure of recharge groundwater are recharged in the collection utilization that particularly relates to the road surface rainwater.

Background technology

Water is Source of life, and using water wisely has become human instant focal issue.Because a large amount of exploiting groundwaters of people; Some urban groundwater moisture storage capacitys sharply reduce; Groundwater table reduces year by year, and the urban ground hard placeization has been destroyed the passage of natural water circulation in addition, and rainwater drops to building area or hardened ground and can not carry out water circulation with natural way again; Thereby cause the moisture content of soil to change, the groundwater run off that natural circulation is formed significantly reduces.As far as general city, except rainy season, most of rainfalls are moderate rain and light rain, and groundwater table lower season at a time when this, rainwater all is to have bled off through row of conduits, can not penetrate into groundwater feed underground water effectively, is a kind of waste of water resource.At present, groundwater recharge more and more receives people's attention.

Summary of the invention

The purpose of the utility model provides the underground backflow device of a kind of road rain water, collects and utilizes road rain water, solves all problems of discharging of prior art road rain water system.Beneficial effect is: the rainwater that utilizes roads rain inlet to collect carries out underground recharging; Arrange recharge well along road; Have the advantages that to disperse to recharge supply, city overall large tracts of land recharge groundwater, the effect of having played the water resource self-restraint and having preserved the ecological environment; Can reduce the burden of drainage system against rain again, good social benefit and environmental benefit are arranged.

The utility model is realized through following technology:

The utility model comprises inlet for stom water 1, communicating pipe 2, recharge well 3, and inlet for stom water 1 is through linking to each other with recharge well 3 communicating pipe 2.The rainwater that drops on road surface 8 and sidewalk 9 flows into inlet for stom water 1 through surface runoff; Inlet for stom water 1 has two outlet openings; A siphunculus 2 in succession, another connects bleed off pipe 7, and bleed off pipe 7 is than communicating pipes 2 height; The rainwater at rainfall initial stage is basic all to flow into recharge well 3 through communicating pipes 2, when recharge well 3 be in saturation state or rainfall when big communicating pipes 2 draining discharge not as good as just passing through bleed off pipe 7 inflow storm sewers.Recharge well 3 is made up of water-permeable pipe 4, filtering layer 5 and seal 6, and recharge well 3 is rounded, and in the middle of water-permeable pipe 4 was positioned at, the periphery of water-permeable pipe 4 was a filtering layer 5, and seal 6 is positioned at the top of filtering layer 5.The rainwater that flows into recharge well 3 flows into filtering layers 5 through water-permeable pipe 4, and filtering layer 5 forms an aquifer, and rainwater is stored in the filtering layer 5 and slowly infiltrates to soil, realizes that rainwater is underground to recharge.

Description of drawings

Fig. 1 is the underground backflow device structural representation of road rain water;

Fig. 2 is the underground backflow device layout plan of road rain water.

Among the figure: 1-inlet for stom water, 2-communicating pipe, 3-recharge well, 4-water-permeable pipe, 5-filtering layer, 6-seal, 7-bleed off pipe, 8-road surface, 9-sidewalk.

The specific embodiment

The utility model structure is seen Fig. 1, and layout is seen Fig. 2, arranges inlet for stom water 1, the location arrangements recharge well 3 of corresponding inlet for stom water 1 according to the road drainage design drawing.Ordinary Rd inlet for stom water spacing is recharged effect in order to improve between 30～50 meters, can between two inlets for stom water, increase recharge well 3.Between inlet for stom water 1 and recharge well 3, adopt communicating pipe 2 to be communicated with, communicating pipe 2 is the pvc pipe of 200 millimeters of diameter phi, and communicating pipe 2 should have the gradient, should be consistent along the communicating pipe 2 of road direction with road grade, and bleed off pipe 7 connects the road rain water pipeline.Should guarantee bleed off pipe 7 when building inlet for stom water 1 by laying bricks or stones than communicating pipes 2 height, to manage concordant being advisable in top with communicating pipes 2 at the bottom of bleed off pipe 7 pipes.Recharge well 3 takes boring or manually digging hole mode to construct, 800 millimeters of hole diameters, and the degree of depth is decided according to actual conditions, is higher than groundwater table and is advisable for 1 meter, and it is good more to recharge effect more deeply, but difficulty of construction and operating expenses can increase general 5～10 meters of the degree of depth.Place water-permeable pipe 4 in the central authorities of recharge well 3, water-permeable pipe 4 adopts the flexible porous tube of 200 millimeters of diameter phi, flexible porous tube be a kind of have collection permeable with filtration be the drainage tubing of one.Filtering layer 5 is filled out in the periphery of water-permeable pipe 4, and filtering layer 5 adopts sand gravel.Fill out seal 6 in 500 millimeters scopes of well head, adopting clay to ram, seal 6 plays filtering layer 5 and stops the upwards effect of infiltration of rainwater when saturated.Top requires backfill according to road construction, construction road surface 8 and sidewalk 9, and the utility model is implemented to accomplish.
