Sewage filtering combined drainage pipe and drainage method

Abstract

The invention belongs to the technical field of building materials, in particular to a sewage filtering combined drainage pipe for both sides of a road and a drainage method. The sewage filtering combined drainage pipe comprises a diversion drainage guide pipe, a connecting pipe, a water purification drainage pipeline, a water baffle and a water filtering plate. The diversion drainage guide pipe and the water purification drainage pipeline are arranged in parallel, and the diversion drainage guide pipe is provided with a sewage inlet. The connecting pipe is arranged between the diversion drainage pipe and the water purification drainage pipe for enabling the diversion drainage pipe to communicate with the water purification drainage pipe. A lifting water blocking plate is arranged in the connecting pipe to act as a water gate, and the water filtering plate is arranged on the side, close to the water purification drainage pipe, of the water filtering plate for filtering sewage. According to the sewage filtering combined drainage pipe, pollutants in the sewage can be effectively removed by arranging a combined pipeline and the water filtering plate, the filtered water is obtained, thus the filtered water can be recycled, and large-scale water resource waste is avoided.

Description

technical field [0001] The invention belongs to the technical field of building materials, in particular to a sewage-filtering combined drainage pipe used on both sides of a road and a drainage method. Background technique [0002] At this stage, the conventional sewage drainage pipes on both sides of the road in the industry can play the function of rainwater removal, but they cannot effectively purify various pollutants contained in them, which not only causes waste of water resources, but also may cause serious pollution. secondary pollution. [0003] However, the existing sewage filter pipes in the market have low efficiency in filtering pollutants in sewage. When the rainfall is large, the excess water storage cannot be effectively removed, and there are problems of difficulty in replacement and maintenance and high cost. In practical applications The results achieved were not ideal. Contents of the invention [0004] The technical problem to be solved by the presen...
