Problems solved by technology

The disadvantage of this type of connected cement pipe is that the connection becomes the weak point in the pipeline
In addition, in pipeline construction, it is often blocked by other pipe networks or obstacles that criss-cross. It is very difficult for hard and straight cement pipes to cross these obstacles. Usually, other pipe networks are deformed or diverted. A headache for construction workers

Embodiment Construction

[0016] After the completion of the underground earthwork excavation, clean up and arrange the heights of all the entry points involved in the drainage of this pipeline, the joint points with the same pipeline network, and all obstacles in this pipeline, and ensure that all raised points are lower than In the case of each water inlet, the general direction of the drain pipe must have a gradual transition from high to low. The skeleton of the drain pipe is composed of a spiral steel core plastic strip, distance control rope, polypropylene woven cloth and steel wire mesh. The core plastic bar outer layer plastic is selected polyethylene plastic, and its thickness is 1 / 4 of steel core diameter, and steel core then is made of steel wire rope, and steel core plastic bar forming method carries out by known molding process with plastic extruder. The ratio of the diameter of the steel core plastic strip to the diameter of the spiral tube is 1:50, and each adjacent ring of the spiral tub...

Abstract

A method for constructing urban underground integrated drainage pipes, using spiral steel core plastic strips as the skeleton, combining distance control ropes, polypropylene woven cloth and steel mesh, and pouring cement mortar between the woven cloth and steel mesh , It can easily bypass various obstacles, eliminate weak links in the pipeline, and reduce engineering investment.

Description

[0001] This application is a divisional application with the application number 2005100224639, the application date is December 30, 2005, and the name is "Urban Underground Integral Drainage Pipe". 1. Technical field [0002] The invention relates to an underground drainage system in an integrated urban municipal engineering, in particular to a construction method for an integrated urban underground drainage pipe 2. Background technology [0003] Presently known urban underground drainage pipes all connect the finished cement pipes section by section. The disadvantage of such joint cement pipes is that the joint becomes a weak point in the pipeline. In addition, in pipeline construction, it is often blocked by other pipe networks or obstacles that criss-cross. It is very difficult for hard and straight cement pipes to cross these obstacles. Usually, other pipe networks are deformed or diverted. A headache for construction workers. 3. Contents of the invention [0004] Th...
