Description

The permeable inlet for stom water facility system of deep gouge formula
Technical field
The utility model relates to the Application of Urban Rain Water field, relates in particular to rainwater indirect utilization facility system.
Background technology
Rainwater utilization is divided into rainwater usually and directly utilizes and the rainwater indirect utilization.The direct utilization of rainwater is meant the construction rain water collecting system, and the rainwater on certain catchment area is collected by gathering system, is stored in the rainwater collecting pit, is used for purposes such as greening, carwash after treatment.The rainwater indirect utilization is that rainwater is permeated the ground by all means, replenishes underground water, improves the ecological environment.
Because the urbanization development causes the impermeable surface area to increase, peak flood flow also increases thereupon, admit the flood control of water body to have higher requirement to city river and downstream, therefore to take the rain penetration measure, can reduce rainfall runoff amount and flood in the city, replenish underground water, increase the water content of thin solum, regulate the climate, improve Urban Water Environment and ecological environment.
China's rain penetration process application does not especially still have effective measure to waterproof ground rainwater infiltration still in the starting stage at present.Usually the rainwater on China's urban road is collected the back by inlet for stom water and is used the line transportation rainwater inspection well, enters river, downstream, canal by the rainwater main then.Its conventional way is: inlet for stom water tube connector rainwater inspection well rainwater main river, canal.This way in today that urbanization develops rapidly, increases the cross dimensions of rain-water drainage facility, and engineering cost increases.Because the rainfall runoff amount increases, cause flood simultaneously, be unfavorable for ecological environment.
In recent years, the urban rainwater infiltration technology of home and abroad develops, and a lot of rain penetration technology are utilized, as infiltration ditch, infiltration well, infiltration blind pipe etc.These technology in use find also to exist drawback, as the blockage problem of permeable hole, the heavy mud problem of infiltration well etc., are effectively solved as yet.
Summary of the invention
Shortcoming and deficiency that the utility model exists for solving present drainage system against rain provide a cover deep gouge formula permeable inlet for stom water facility system.
Technical solution of the present utility model is achieved in that this system comprises permeable inlet for stom water of deep gouge formula and Permeable blind pipe.The permeable inlet for stom water of deep gouge formula mainly is in its bottom heavy mud groove to be set, and silt sinks to the mud bottom land in the water, and remove dry season.Wall perforation around the permeable inlet for stom water of the deep gouge formula middle part, and wrap up permeable geotextiles, periphery is filled the gravel loaded filter; Rainwater is permeated the ground.The permeable inlet for stom water of deep gouge formula top is provided with bleed off pipe unnecessary rainwater is introduced the urban sewerage and drainage main or introduced the rainwater retention system.Connect with Permeable blind pipe between the permeable inlet for stom water of each deep gouge formula, the perforation of Permeable blind pipe periphery, with permeable geotextiles parcel, periphery is filled the gravel loaded filter, increases the infiltration area with this.
Heavy mud groove is set is used for depositing rainwater silt.
In the middle part perforation of the permeable inlet for stom water well of deep gouge formula is to stop up hole in order to reduce silt.
The permeable inlet for stom water of deep gouge formula import department adopts encrypts cast iron grizzly bar well grate, in order to the interception foreign material.
Connect with Permeable blind pipe between the permeable inlet for stom water of deep gouge formula, outsourcing gravel loaded filter is in order to increase the infiltration area, to increase the rainwater time of staying.Rainwater is distributed in road to permeate the ground along the line gradually.
Permeable blind pipe is buried underground near kerb is parallel, can avoid motorway, is convenient to maintenance management.And can reduce the ring stiffness of tubing, reduce engineering cost.
Bleed off pipe is every the well setting, surplus water entered the urban sewerage and drainage main or water is introduced the rainwater retention system be used to water greenery patches, carwash, landscape water or municipal miscellaneous water etc.Reach throttling and reduced discharging the purpose of improving the ecological environment.
The beneficial effects of the utility model are: combine with conventional drainage system, and simple, flexibility and reliability.Both can reduce rainwater surface runoff amount, and unnecessary rainwater can have been stored again and utilize, kill two birds with one stone.
