Abstract
The invention discloses a permeation and drainage pipe duct for comprehensively utilizing rainwater, which consist of a group of finished polyethylene permeation rainwater wells and a polyethylene solid wall perforated pipe duct, wherein each permeation rainwater well comprises three types of wells, namely a permeation rainwater well, a split-flow permeation rainwater well and a water collecting permeation rainwater well; the wall and the bottom of each wall are perforated; a permeation pipe duct is a rectangular-section horizontal water collecting square duct of which the outside is coated with geotextile and the inside is filled with aggregate; a perforated pipe is arranged in the duct; and adjacent permeation rainwater wells are connected with each other through a perforated pipe. The permeation and drainage pipe duct has comprehensive functions such as collection, storage, delivery, permeation and drainage of rainwater, and is used in regions of which soil has certain water permeability; and due to the adoption of the permeation and drainage pipe duct, the peak discharge can be effectively reduced, the occurrence time of a flood peak is delayed, underground water is replenished, and the water content and air humidity of soil are increased.
Description
Technical field
The present invention relates to a kind of Storm Sewer Network of rainwater comprehensive utilization facility, especially one residential.
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 the supply of rainwater to underground water.Urbanization process has been aggravated the sclerosis on ground, underground water obtains from rainfall increment is less and less, a large amount of rainwater with multiple area source pollutants pour in pipe network, and in advance, flow strengthens flood peak, pipe network can't bear the heavy load, the hydrologic cycle of nature and urban ecological environment more become to worsening, and present city and develop more, and invest larger, drainage is more complete, the strange phenomenon that flood is more serious.Therefore, the angle innovation storm-water drainage technology of an urgent demand from keeping the nature hydrologic cycle 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 nature hydrologic cycle, repair ecological environment, the invention provides a kind of infiltration-drainage pipe duct for comprehensive utilization of rainwater, be applicable to soil the newly-built of certain percolating water ability area and the Storm Sewer Network of reconstructing are arranged, it has rainwater-collecting, stores, carries, infiltrates, transfers storage discharging comprehensive function, can economize the land resource, the flood peak clipping flow, delay the time that flood peak occurs, supplemented underground water, improve moisture content and the air humidity of soil.
The technical solution adopted for the present invention to solve the technical problems is: infiltration-drainage pipe duct for comprehensive utilization of rainwater is comprised of one group of polyethylene finished product penetrating catch basin and the real wall perforated pipe infiltration of polyethylene pipe duct two parts.Penetrating 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, percent opening 1～3%, aperture 16mm, rain 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, and geotextiles encloses the 100mm coarse sands layer outward, 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 formula; D-perforated pipe internal diameter mm; L-length of pipe section m; The i-perforated pipe gradient, i=1～2%.Be laid on the perforated pipe in macadam, two ends are connected with penetrating 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 lower than the pipe of outlet pipe at the bottom of or flush, be Δ h 〉=0, make pipe duct can store a certain amount of rainwater when rainfall.Infiltration-drainage pipe duct for comprehensive utilization of rainwater, penetrating catch basin and perforated pipe pipe duct share foundation trench.
During rainfall, the rainwater that the roof drainage system is discharged is in the waterpower self-cleaning filter enters abandoned stream infiltration catch-basin, and early-stage rainwater enters and cuts the dirt basket by filter plate, and rainfall early-stage rainwater later permeates the ground, and cuts the dirty basket of mud of holding back and regularly removes.Comprise that oozing the saturating well of rainwater imports with other environmentally-friendly gutter inlets the whole rainwater that ooze sewer from catchmenting, 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 pipe duct.Accumulate infiltrating and on the impact of the hydrology, environment, being a long-term process of rainwater.
The invention has the beneficial effects as follows, can effectively reduce the pollution of area source of rainwater, save land resources, reduce discharge value, alleviate the discharge pressure of existing drainage pipeline networks, reduce the drainage pipeline networks investment cost, the recharge of groundwater source, keep the nature hydrologic cycle and repair ecological environment, good economic benefit and social benefit are arranged.
