Horizontally-placed deposition-proof rain sewage pipe

Abstract

The invention discloses a horizontally-placed deposition-proof rain sewage pipe. The horizontally-placed deposition-proof rain sewage pipe comprises a pipe body (1) of which the radial direction is circular. A bore-type spiral hollow (2) is formed in the inner wall surface of the pipe body (1). Because the bore-type spiral hollow (2) is formed on the inner wall surface of the pipe body (1), the rain sewage is stirred in the rotation state and passes through the pipe body (1), so the deposition of sludge on the lower inner wall of the pipe body (1) is avoided or reduced.

Description

technical field [0001] The invention belongs to drainage pipes, in particular to a horizontal anti-silting rain and sewage pipe. Background technique [0002] The existing rainwater and sewage pipes have a flat inner wall. After a long time of use, the inner wall of the pipe body will be silted up, so that the diameter of the pipe body becomes smaller and smaller. Because the rainwater pipe is buried underground, it is difficult to replace or pass through it. . Therefore, it is of great significance to provide a horizontally placed rainwater pipe for avoiding or reducing mud deposition. Contents of the invention [0003] The object of the present invention is to provide a horizontally placed anti-silting rain and sewage pipe. [0004] The present invention is a horizontal anti-silting rain and sewage pipe, which comprises a pipe body with a circular diameter. The inner wall of the pipe body is formed with a gun bore type spiral depression. [0005] The present invention...
