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

[0015] 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

Since present city underground drainage pipe are constructed by connecting the cement pipes section by section, the construction is troubled by other pipe network, and the connection between sections are weak. The invention provides a city underground integrated drainage pipe which uses screw steel core plastic rod as frame, combined with distance controlling line, polypropylene woven cloth and steel network to be irrigated with cement sand slurry. It can easily avoid variable obstacles and eliminate the weak connection to reduce the cost.

Description

1. Technical field [0001] The invention relates to an underground drainage system in an integral urban municipal engineering, in particular to an integral urban underground pipe. 2. Background technology [0002] 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 [0003] The purpose of the present invention is to provide an urban underground integrated drainage pipe to solve the difficult problems in the construction of the urban underground drainage pipe network. [0004] The purpose of the present invent...
