Abstract

The utility model relates to a novel ecological rain collection pipeline capable of rain collection and runoff pollution control, which adopts a box-type or an open-type structure. In the case of an open-type structure, a steel fiber ecological concrete cover plate is provided on the upper part; and in the case of a box-type concrete structure, a porous structure is used peripherally, the box-type structure made of ecological concrete cooperating with a lower layer of gravel sand cushion to form a rain filtering system. The utility model solves the problems of urban aquatic environment pollution, ecological damage, divagation of effluvium, and propagation of mosquito and flies caused by conventional reinforced concrete pipes or plastic pipes handily discharging collected rain into urban water courses. The utility model is advantages by effective rain collection and purification, perfect filtering performance, full utilization of purification function of soil, capability of repurification of rain, reduced rain amount of rainfall discharged into water courses, relief of urban flood control stress as well as decreased pollution load on rivers, shortened retarding duration of rainwater in gullies, and elimination of factors for propagation of mosquito and flies.

Description

Novel ecological collection rain rill
Technical field
The utility model relates to a kind of dewatering installation that catchments, particularly a kind of novel ecological rainwater collection conduit of collecting rainwater and runoff pollution control.
Background technology
Non point source of pollution shared proportion in water pollutes in city constantly increases, and pollution of area source also becomes the another main cause that influences the water body environment quality gradually.City surface source is the diffuse polluting source that is created in the city area, because human living and activity are the most intensive in the city, and most of zone belongs to impermeable surface, so city surface source pollution intensity is big, easily flows out with rainwater, and is also bigger to Effects of water environment.Along with quickening of urbanization process, city surface source pollution shared proportion in the urban water-body pollution sources constantly increases.It is reported uptown surface runoff pollutant mean concentration BOD 5Can reach 3.6mg/L, COD CrReach 40mg/L, commercial area surface runoff pollutant mean concentration BOD 5Be 7.7mg/L, COD CrReach 39mg/L.According to interrelated data estimation, it is that the pollutant that the rainfall of 12.7mm is washed in " three rivers " is BOD that Chengdu in 1994 continues 1h intensity 52.35t, COD Cr11.2t, TN0.32t, TP0.06t; Average every the rainfall in Beijing in 2000 produces COD Cr121t is equivalent to COD CrSanitary sewage 240,000 t of 500mg/L.City surface source has become one of key factor that influences Urban Water Environment, the development of restriction municipal water ecosystem health.
Before the present utility model, traditional rainwater is collected and is adopted concrete reinforced pipe or plastic pipe to collect, and finally enters city river nearby, has both polluted Urban Water Environment, has destroyed ecology, influences civic landscape again.The water environmental problems such as stench that produced have become one of focus of citizen's complaint thus.In addition, traditional storm drain in the city causes the open drain dark and damp because rainwater remains in a standstill, environmental problem, serious threat townsfolk's life and health safety such as also exist mouse to haunt, mosquitos and flies multiplies.
Summary of the invention
The purpose of the present utility model just is to overcome above-mentioned defective, design, a kind of novel ecological collection rain rill of development.
The technical solution of the utility model is:
Novel ecological collection rain rill adopts box or open form structure, and steel fibre eco-concrete cover plate is established on top when adopting the open form structure, it is characterized in that being around box concrete structure loose structure.
Advantage of the present utility model and effect are to utilize the loose structure of eco-concrete structure, form porous eco-concrete structure ratio and have good filterability, cooperate with lower floor gravel bed course and to form the dmp filter system, effectively collect rainwater, purify rainwater pollution, has good filterability, rainwater is oozed under directly, help making full use of the purification function of soil, realization is to the further purification of rainwater, significantly reduce the amount of rainfall that enters the river course, both alleviated the pressure of flood in city, reduced the pollution load in river again effectively, reduce the viscous flow time of rainwater in ditch simultaneously, eliminated the breeding environment of mosquitos and flies.
Description of drawings
Fig. 1---the utility model structural principle floor map.
The A-A sectional drawing of Fig. 2---Fig. 1.
The specific embodiment
As shown in Figure 1 and Figure 2, be ecological open channel form, adopt the prefabricated case structure 1 of special eco-concrete, be loose structure around the box concrete structure, porosity reaches 30%; Be cover plate 2 above, the gravel bed course below the left and right sides wallboard of porous and base plate and the case structure 1 cooperates formation dmp filter system.
When rainy, rainwater flow in the box concrete structure 1, rainwater cooperates the dmp filter system filtration that forms through left and right sides wallboard and base plate with the gravel bed course of bottom and periphery, permeate the ground, replenish underground water, reduced flowing into the amount of rainfall in river again, and in time got rid of rainwater and reduced the viscous flow time of rainwater in ditch again, eliminated the mosquitos and flies breeding environment.
The utility model also can adopt open type, plate 2 not with cover.
The utility model is according to site condition and needs, and box concrete structure 1 also can remove cover plate 2 and become open type.Box concrete structure 1 can adopt direct burial or shallow embedding formula.
