Description

Flexible multifunctional rainwater inlet sewage intercepting bag and rainwater well

Technical Field

The invention relates to the technical field of environmental protection and outdoor drainage engineering, in particular to a flexible multifunctional rainwater port sewage intercepting bag and a rainwater well.

Background

The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art.

The rainwater inlet refers to a water inlet structure for collecting rainwater on the ground by an outdoor drainage pipeline, generally is a well with a water inlet grate and is used for outdoor drainage projects such as municipal roads, squares, districts and the like. Before entering the rainwater inlet, rainwater flows through the roof and the ground to form surface runoff, washes away pollutants such as garbage, soil, dust, oil stain, organic matters, heavy metals and the like accumulated on the surface, and then brings the pollutants into a drainage canal system and a downstream water body through the rainwater inlet. In non-rainy seasons, the gully is also a place for gathering pollutants due to environmental sanitation cleaning and road washing. On one hand, the pollutants are easy to deposit in the gully and the pipe canal, so that the drainage capacity of the drainage system is influenced, and the workload of cleaning and maintaining the drainage system is increased; on the other hand, the pollutants are discharged into a downstream water body through a rainwater port and become one of the main pollution sources of the water environment pollution. Meanwhile, the rain inlet and the sewer are also places for breeding mosquitoes and flies, and the environmental sanitation of cities is affected.

The traditional widely used rainwater port generally only depends on the rainwater grate to intercept bulky objects, and other pollution interception measures are few. Some deepen inlet for stom water, establish the precipitation tank in the catch basin bottom, get rid of partial pollutant through simple sediment, nevertheless increased the work load of inlet for stom water desilting. The dredging operation is time-consuming, labor-consuming and inconvenient. The mode has a common sewage interception effect, and if the sewage is not cleaned in time, the sewage is easy to block a pipeline, so that the water body pollution is caused.

The main problem faced at present is how to solve the above problems to the greatest extent possible by modifying the structure of the gully or adding a device on the premise of ensuring the water passing capacity of the gully. At present, some technical solutions for adding a sewage interception device to a gully or providing a whole finished product sewage interception type gully have appeared.

Secondly, cut dirty and drainage function and be difficult to compromise, inlet for stom water drainage ability receives the influence of certain degree, influences drainage safety. Thirdly, the sewage interception and fixing device is inconvenient to install, disassemble, transport, clean and maintain, and the whole cost or maintenance cost is high.

Wherein, some technical scheme adopt to cut dirty basket, trash rack, cut dirty string bag, filtration string bag etc. and cut dirty device, because the shape of cutting dirty major structure, trompil mode are unreasonable, can only intercept thick floater when the rainwater flows through, and pollutants such as tiny particulate matter and greasy dirt pierce through easily and cut dirty device, cut dirty ability and lower. Some technical scheme adopt complicated hanging isolating device, guiding device, overflow arrangement and deposit, filter etc. and cut dirty device and make up, and the structure generally comprises several parts members of rigidity or flexibility, and the structure is complicated, but water capacity and cut dirty effect and hardly compromise, and installation, clearance are very inconvenient. Meanwhile, the prior art scheme generally has no enough pollutant storage space, and water blocking easily occurs along with accumulation of pollutants.
