Description

Sewer is oozed in a kind of rainwater comprehensive utilization
Affiliated technical field
The utility model relates to a kind of rainwater comprehensive utilization facility, especially builds the Storm Sewer Network of sub-district.
Background technology
For a long time, people give Urban Rainwater Pipe Networks single rainfall runoff discharge function, and a large amount of rainwater run off in vain, have cut off rainwater to phreatic supply.Urbanization process has been aggravated the sclerosis on ground, the increment that underground water obtains from rainfall is less and less, a large amount of rainwater that have multiple area source pollutants pour in pipe network, and flood peak shifts to an earlier date, and flow strengthens, pipe network can't bear the heavy load, the hydrology circulation and the urban ecological environment of nature more become to worsening, and present the city and develop more, and invest big more, drainage is complete more, the strange phenomenon that flood is serious more.Therefore, the angle innovation storm-water drainage technology of an urgent demand from keeping the circulation of the nature hydrology and repairing ecological environment.
Summary of the invention
In order fundamentally to overcome the deficiency of existing drainage system against rain, demonstrate fully the resource theory of soil and rainwater, keep the circulation of the nature hydrology, repair ecological environment, the utility model provides a kind of rainwater comprehensive utilization to ooze sewer, be applicable to that soil has the newly-built of certain percolating water ability area and the Storm Sewer Network of reconstructing, it has rainwater and collects, stores, carries, infiltrates, transfers storage discharging comprehensive function, can economize the land resource, cut down peak flood flow, delay the time that flood peak occurs, replenished underground water, improve the moisture content and the air humidity of soil.
The technical scheme that its technical problem that solves the utility model adopts is: rainwater comprehensive utilization is oozed sewer and is made up of one group of polyethylene finished product infiltration type catch-basin and polyethylene reality wall perforated pipe pipe duct two parts.The infiltration type catch-basin comprises infiltration catch-basin, abandoned stream infiltration catch-basin, three kinds of well types of catchment infiltration catch-basin, the equal perforate in the borehole wall and shaft bottom, and percent opening 1~3%, aperture 16mm has the rainwater infiltration function.The infiltration catch-basin adopts common well lid.The rain penetration well that catchments adopts well to comb, and establishes below well is combed and cuts dirty basket.Abandoned stream infiltration catch-basin, inlet tube and outlet tube below are established and are cut dirty plate, cut dirty plate and are seated on the dirty basket of cutting of bottom, well chamber, cut dirty basket liner geotechnique cloth bag.The infiltration pipe duct is an outsourcing geotextiles, the inner level side of catchmenting canal of filling the rubble rectangular cross section, geotextiles outer periphery 100mm coarse sands layer, ballast grain sizes 25~30mm, braiding channel width B=D+ (2 * 200), the high H=D+ of canal (2 * 200)+Δ H, Δ H=iL in the formula; D-perforated pipe internal diameter mm; L-length of pipe section m; The i-perforated pipe gradient, i=1~2%.Be laid on macadam middle punch pipe, two ends link to each other with the infiltration type catch-basin. in abandoned stream infiltration catch-basin, inlet tube and outlet tube pipe top flushes. in infiltration catch-basin and catchment infiltration well rainwater, the Guan Dingying of water inlet pipe is lower than at the bottom of the pipe of outlet pipe or flushes, be Δ h 〉=0, make pipe duct when rainfall, can store a certain amount of rainwater.Sewer, infiltration type catch-basin and the shared foundation trench of perforated pipe pipe duct are oozed in the rainwater comprehensive utilization.
During rainfall, the rainwater that the roof drainage system discharges is in the waterpower self-cleaning filter enters abandoned stream infiltration catch-basin, and early-stage rainwater enters by filter plate and cuts the dirt basket, and rainfall early-stage rainwater later permeates the ground, and cuts the dirty basket of mud of holding back and regularly removes.Comprise from catchmenting and ooze whole rainwater that sewer is oozed in saturating well of rainwater and the remittance of other environmentally-friendly gutter inlets, flow further downstream under the effect of pipe duct starting point catch-basin and landscape water body water surface discrepancy in elevation H2-H1, simultaneously, rainwater permeates the ground, and is accumulated in the pipe duct.Accumulate infiltrating and being a long-term process of rainwater to the influence of the hydrology, environment.
The beneficial effects of the utility model are, can effectively reduce the pollution of area source of rainwater, save land resources, reduce discharge value, alleviate the draining discharge pressure of existing drainage pipeline networks, reduce the drainage pipeline networks investment cost, replenish underground water source, keep the circulation of the nature hydrology and repair ecological environment, good economic benefit and social benefit are arranged.
