Description

A kind of road drainage filter structure system

Technical field

The invention belongs to draining of catchmenting, dmp filter to purify treatment technology control field of regulating and storing, more particularly to a kind of road Road draining filter structure system.

Background technology

Sponge city, it is new generation of city storm water man- agement concept, refers to that city is adapting to environmental change and reply rainwater band Natural calamity come etc. has good " elasticity ", also referred to as " water elasticity city ".International term is " low shadow Ring exploitation storm-water system structure ".Rain when water suction, water storage, infiltration, drainage, water purification, it is necessary to when by the water stored " release " and plus To utilize.

An important method of the permeability road surface as " Demonstration for Ecological Sanitation ", have become road drainage design one are important Part.Porous pavement is applied to pavement, car lane, lightweight track and various stadium roads, conventional permeable road Face engineering has no unified standard, and road surface is permeable, gas permeability is not high, and wherein water permeable concrete rough surface, bearing capacity are low；Water-permeable brick Permeable by pore, the time easily blocks for a long time, and waterproof with cement bonded sand or fine-stone concrete laying, bearing capacity is also poor, and cost is high；Also Plastic tube frame mould, i.e., be first put on bed course, penetration concrete by the method for having some permeable cement road surfaces to use pre-buried pipe support, After concrete drying, multiple through holes that pipe support mould is set then turn into osculum, higher using such method cost, Engineering time is grown, and because architectural surface is waterproof pavement material, if be combined with pipe support method pervious concrete pavement, Permeable effect can not be then played, it is environmentally friendly to be taken into account with attractive in appearance.

With the development of urbanization process, the area rapid growth on impermeable ground, pollutant is caused to be accumulated so that road Hold substantial amounts of pollutant in the rainwater of face, show in the research of some pavement runoffs, the pollution in initial stage 30% rainfall runoff is born Lotus accounts for the 70% of whole field rainfall pollution, and therefore, the water body that retention and the processing of early-stage rainwater can effectively control runoff zones is dirty Dye.At present, also there is different measures for rainwater pollution processing both at home and abroad, foreign countries are directly to collect rainwater again mostly Utilize, the country is that early-stage rainwater is introduced directly into sewage treatment plant, have ignored sewage treatment plant's decontamination finite capacity, unnecessary sewage It is unprocessed to be directly discharged into natural water.Therefore, it is necessary to develop the Initial Runoff rainwater section that can make up these aspect deficiencies Dirty processing unit, collect and purifying city road surface rainwater, and with purification, filtering after storm water conservation lawn, raising water resource Utilization rate, the present invention realizes the integration of catchment, cut dirty, filtering, water purification and irrigation function, it is possible to achieve more efficiently Water storage, economic and practical, construction is simple.
