High-strength underground drainage system

Abstract

The invention discloses a high-strength underground drainage system, which comprises a plurality of sections of pipe bodies and telescopic joints connected between adjacent pipe bodies and used for water seepage confluence and telescopic connection of the adjacent pipe bodies. Each pipe body comprise an arched pipe body and a rectangular pipe body which are arranged up and down and are integrallyformed, a plurality of water seepage holes formed in the arched pipe body, and a reinforcing rib of which one end is connected to the inner wall of the arched pipe body and the other end of which is connected to the inner wall of the rectangular pipe body; and connecting lugs for extruding the telescopic joints on the pipe bodies are arranged between the pipe bodies and the telescopic joints. By means of the scheme, the drainage system has the advantages of simple structure, reliable connection, high pressure bearing capacity and the like, and has high practical value and promotional value inthe technical field of drainage.

Description

technical field [0001] The invention relates to the technical field of drainage, in particular to a high-strength underground drainage system. Background technique [0002] In the construction of railway tunnels, it is necessary to stack the excavated slag in areas such as ravines, flat ground, and hillsides; because the newly piled earth and rock are relatively loose, their stability is poor; on the one hand, some parts of the earth and rock are inherently Moisture; on the other hand, in the case of rain or humidity, water will seep down to the contact surface of the pile, so that it is easy to cause the problem of landslide of piled slag; similarly, not only in the construction of railway tunnels There are such problems, and the same problems exist in fields such as road construction and water conservancy excavation. Contents of the invention [0003] In view of the problems referred to above, the object of the present invention is to provide a high-strength underground...
