Embodiment Construction

[0012] The technical solution of the present invention will be further described in detail below.

[0013] This method of replacing a sewer pipe includes the following steps:

[0014] (1) Divide into several construction sections according to the different diameters and breaking points of the sewage pipes;

[0015] (2) Set up the first working pit and the second working pit at both ends of each construction section;

[0016] (3) Put new pipes in the first working pit;

[0017] (4) Install pipe drawing machine equipment in the second working pit;

[0018] (5) Insert the tool for breaking and expanding the pipe into the old pipe from the second working pit to crush the old pipe;

[0019] (6) Use the pipe pulling machine to pull the new pipe into the position of the old pipe. That is to say, a conical expanding tool is inserted into the old pipe as a guide, and the old pipe is broken by pulling force, and the broken pipe fragments are squeezed into the surrounding soil, and t...

Abstract

The invention discloses a method for replacing a sewage pipeline, which does not disturb residents or destroy foundation of surrounding buildings, does not influence traffic, hardly pollutes the environment and has low construction cost. The method comprises the following steps: (1) dividing a sewage pipeline into a plurality of construction sections according to diameter differences and break points of the sewage pipeline; (2) forming a first work pit and a second work pit at two ends of each construction section; (3) putting a new pipeline in the first work pit; (4) assembling tube drawing bench equipment in the second work pit; (5) inserting tools for crushing and expanding pipelines into an old pipeline from the second work pit to crush the old pipeline; and (6) drawing a new pipeline to the position of the old pipeline by the tube drawing bench equipment.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and in particular relates to a method for replacing sewage pipes. Background technique [0002] At present, many underground sewage pipes in China are leaking due to aging, and it is urgent to replace new sewage pipes. However, since there are generally many residential quarters, commercial facilities, traffic lines, etc. on the ground where the underground sewage pipeline is located, if all of them are excavated, it will seriously affect people's lives, damage the foundation of surrounding buildings and underground pipelines, interfere with traffic, pollute the environment, and cause construction pollution. The cost is huge. Contents of the invention [0003] The technical problem of the present invention is: to overcome the deficiencies of the prior art, to provide a method for replacing sewage pipes that does not disturb the residents, does not damage the foundation of surr...
