Composite drainage pipe

Abstract

The invention discloses a composite drainage pipe, which comprises two semicircular pipe bodies, each of which is provided with an independent discharge channel, and the two semicircular pipe bodies are spliced ​​to form a circular drainage pipe. For the main body of the pipe, there are more than one positioning bushings equidistantly provided on the horizontal end surface of each pipe body, and a through hole communicating with the discharge channel is arranged in the middle of the positioning bushings, and a hole is inserted between two adjacent pipe bodies. Root conduit, the conduit connects the discharge passages inside the two pipe bodies; the present invention is especially suitable for application in the buried field, and can block the water source after being subjected to pressure or shear force, and even if it is cut off, there will be no Any water leakage problem can achieve the purpose of water blocking and reduce the waste of resources.

Description

technical field [0001] The invention relates to a pipeline, in particular to a composite drainage pipeline. Background technique [0002] After the buried drainage pipe is buried in the ground, if there is an external force to cut the pipe, the pipe identification will be broken, and the serious direct fracture will occur. In this case, the medium transported inside the pipe will flow out in large quantities , Before the repair is completed, a large amount of resources will be consumed, resulting in a large waste of resources and economic losses. [0003] For example, the patent number 201811175388.3, ​​the patent name is a buried pipeline structure, which solves the problem of improving the corrosion resistance of the pipeline by coating the outer wall of the pipeline with an anti-corrosion paint layer and pasting the anti-corrosion tape. Blocking a large amount of outflow of the transmission medium under certain circumstances will consume a large amount of resources. Co...
