Device for collecting and guiding rainwater at urban road edge

Abstract

The invention discloses a device for collecting and guiding rainwater at an urban road edge, comprising a rainwater inlet and a sedimentation chamber, wherein the rainwater inlet is vertically arranged underneath the road edge, the sedimentation chamber clings to the rainwater inlet, and is arranged below a road surface, the rainwater inlet is in connection with a filter chamber through a water diversion pipe, a movable cover plate is arranged at the top of the filter chamber, a water drainage pipe is arranged at the bottom of the filter chamber, and is in connection with subsequent treatment devices, and filter elements are arranged in the filter chamber. The device disclosed by the invention has the beneficial effects of good sedimentation effect, high filter efficiency, convenience for cleaning and maintenance, and capability of effectively guiding and collecting the rainwater on the road surface and performing pretreatment on the rainwater.

Description

technical field [0001] The invention relates to the field of urban drainage, in particular to a collecting and guiding device for filtering and pretreating rainwater deposition. Background technique [0002] As the source of the urban drainage system, the rainwater collection and guiding device of the rainwater outlet is an indispensable and important part. In the past, people only paid attention to its most basic rainwater collection and guiding function. A large amount of sediment and garbage are brought into the urban drainage pipe network. These sediment and garbage enter the natural water body through the drainage pipe network along with the rainwater, causing natural water pollution and sediment deposition. Flood drainage is not smooth, resulting in urban waterlogging, which is the main reason why many cities have a "seeing the sea" scene during heavy rains in recent years; for this reason, the country puts forward the concept of "sponge city" by referring to the advan...

AI Technical Summary

Problems solved by technology

[0004] 1. The traditional rainwater outlets only have the function of collecting and simple pollution blocking, without sedimentation and filtering components, resulting in rainwater mixed with a large amount of garbage and sediment into the pipeline, resulting in pipeline blockage, and subsequent rainwater purification treatment is difficult;

[0005] 2. Some of the existing new rainwater collection and guiding devices are equipped with fences at the water inlet, and filter parts are installed inside the pipes to intercept garbage and floating objects. However, since no sedimentation chamber is installed to deposit sediment; It is easy to cause clogging of filter components, thereby affecting filtration efficiency;
