Description

Pipeline reconstruction construction system and pipeline reconstruction construction method {SYSTEM AND METHOD FOR PIPELINE RECONSTRUCTION}

The present invention relates to a pipeline reconstruction construction system and a pipeline reconstruction construction method, and more particularly, to a pipeline reconstruction construction system and a pipeline reconstruction construction method for rebuilding a pipeline by arranging a pipeline reconstruction pipe for repairing or replacing an aged pipeline in an old pipeline. it's about

Conventional water supply and sewage duct repair methods are aimed at solving damage or leakage of a specific part of the duct and focus on partial repair, and generally a liner having a thickness of about 0.7 to 2 cm is used. The liner is a tube made of resin material that expands and hardens by heat. In the construction of the liner, a work hole is installed at both ends of the old pipe or an existing manhole is used to secure a work space, and then the liner is inserted into the existing pipe and the liner is inserted into the pipe. Steam or hot water is injected into the tube to expand the liner so that the liner adheres to the inner wall of the existing tube and hardens.

In recent years, due to the deterioration of existing water supply and sewage pipes, there is a growing demand for overall repair or replacement of old pipes instead of partial repairs. However, the liner inserted into the old pipe according to the conventional method only serves to cover the damaged portion of the inner wall of the existing pipe, and cannot replace the existing pipe as a whole because the pipe is thin. On the other hand, in order to completely replace the existing old pipe with a new pipe, excavation work throughout the pipe is required, which is very inefficient in terms of cost and time.

Accordingly, there is a demand for the development of pipeline reconstruction construction technology that can replace or replace the existing pipeline as a whole and replace the existing pipeline even if the existing pipeline is lost, but which can be applied in a non-excavation method.

A plurality of pipeline reconstruction pipes 21 are placed on the work table 10, and the pipeline reconstruction pipe assembly 20 may be formed by fusing and extending the plurality of pipeline reconstruction pipes 21 to each other.

The workbench 10 has a work surface 11 on which the pipeline reconstruction pipe assembly 20 is placed. In order to ensure ease of insertion of the pipe assembly 20 into the pipe 100, the work surface 11 may be formed at the same height as the pipe 100.

The conduit reconstruction pipe assembly 20 is formed by connecting two or more conduit reconstruction pipes 21 inserted into the conduit 100 to repair or replace the conduit 100, and is placed on the work table 10. Referring to FIG. 2 , the pipeline reconstruction pipe assembly 20 is formed by connecting the pipeline reconstruction pipes 21 in an extended form, and a joint between the pipeline reconstruction pipes 21 may be formed by fusion.
