Method and structure for fixing communication pipe of water extraction pump station water absorption pond

Abstract

The invention discloses a method and a structure for fixing a communication pipe of a water extraction pump station water absorption pond. The method comprises the following steps of preliminarily respectively embedding and fixing a waterproof bushing in connection holes on the wall of two water absorption ponds, then inserting two pipe orifices of the communication pipe into the waterproof bushings, ensuring the end surfaces of two pipe orifices of the communication pipe to respectively penetrate through the waterproof bushings, respectively welding a flange piece on the end surfaces of the two pipe orifices of the communication pipe, wherein the inner diameter of the flange piece is identical to that of the communication pipe, the outer diameter of the flange piece is greater than the outer diameter of the waterproof bushing, and adopting a mixed material of fibers and asbestos cement to fill a seam between the communication pipe and the embedded waterproof bushings after the flange pieces are closely attached to the wall of the water absorption pond. By adopting the method, not only can the advantages such as reliability in connection and fixation and safety in use be realized, but also the advantages such as simplicity in structure, convenience in construction and long service life can be realized.

Description

Technical field [0001] The invention relates to a method and structure for fixing a connecting pipe of a suction pool of a water intake pumping station, and belongs to the technical field of making a suction pool of a water intake pumping station. Background technique [0002] At present, many lakes, reservoirs and rivers use fixed shore-type water intake pumping stations. Such water intake pumping stations usually have a large water level. The suction pools of the water intake pumping stations are generally divided into two for regular cleaning and water absorption. A connecting pipe and a connecting valve need to be set between the pools. When cleaning, close the connecting valve on the connecting pipe. When cleaning one of the sumps, the other sump can operate normally. After cleaning, the sump with water flows through the connecting pipe. Fill the cleaned empty pool with water. However, in the prior art, the two nozzles of the connecting pipe are often connected and fixed to...

AI Technical Summary

Problems solved by technology

However, in the prior art, the two nozzles of the connecting pipe are often connected and fixed on the connection hole of the water-absorbing pool wall in a tight-fitting manner. When it is high and becomes larger, when its pressure overcomes the maximum friction between the connecting pipe and the pool wall, the connecting pipe will fall off from the pool wall of the suction pool and cause an accident.

Therefore, the fixing method of the connecting pipe in the suction pool of the existing water intake pumping station is not ideal, and cannot meet the needs of use
