Embodiment Construction

[0014] The technical solution of the present invention will be further described in detail below.

[0015] This method of replacing a sewer pipe includes the following steps:

[0016] (1) Divide into several construction sections according to the different diameters and inflection points of the sewage pipes;

[0017] (2) Set up the first working pit and the second working pit at both ends of each construction section;

[0018] (3) Put new pipes in the first working pit;

[0019] (4) Install pipe drawing machine equipment in the second working pit;

[0020] (5) Insert the tool for breaking and expanding the pipe into the old pipe from the second working pit to crush the old pipe;

[0021] (6) Use the pipe pulling machine equipment to pull the new pipe into the position of the old pipe. That is to insert a conical pipe expansion tool 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...

Abstract

The invention discloses a method for replacing sewage conduits, which has the advantages that residents cannot be disturbed, surrounding building foundations and underground pipelines cannot be broken, traffic cannot be interfered, the environmental pollution is low, and the construction cost is low. The method comprises the following steps: (1) performing pre-construction planning; (2) making material and equipment preparations; (3) setting up working pits; (4) making preparations before replacement; (5) performing material fracture treatment; (6) removing old conduits; (7) installing new conduits; (9) filling for reburying.

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 shortcomings of the existing technology for replacing sewage pipes, such as large engineering volume, high noise, serious environmental damage, and high ...
