Short pipe replacement equipment for collapsed pipeline

Abstract

The invention discloses short pipe replacement equipment for collapsed pipelines, which comprises a wall expansion head, a plurality of short pipes, a traction mechanism and a pushing mechanism, the short pipes are used for replacing damaged pipelines, and the short pipes are detachably connected; the traction mechanism is connected with one end of the wall expansion head, the other end of the wall expansion head is detachably connected with one end of one short pipe, and the traction mechanism is used for pulling the wall expansion head to move; and the pushing mechanism is used for pushing the short pipe and the wall expanding head to move. According to the technical scheme, aiming at the problems of low construction efficiency, long construction period and high cost caused by lack of corresponding intelligent equipment when a trenchless short pipe replacement technology is adopted for transformation of old and old pipeline facilities, the invention provides equipment which has an updated equipment structure and can meet construction requirements, so that the construction speed is increased, the construction period is shortened, and the engineering cost is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of pipeline construction, in particular to a short-pipe replacement device for collapsed pipelines. Background technique [0002] With the continuous acceleration of the urbanization process, the administrative departments have gradually strengthened the supervision of the construction of the pipeline network. However, after a large number of buried pipelines are put into operation for several years, due to external forces or their own service life, collapse or leakage accidents will inevitably occur. The pipelines are buried deep underground and are invisible. specific conditions, sometimes these facilities are destroyed without warning. As a result of the damage, the operation is interrupted, and the pipeline owners not only have to bear huge economic losses, but also the relevant parties have to bear great public pressure. The overall replacement of the pipeline is not only costly, but also brings envir...

AI Technical Summary

Problems solved by technology

[0005] The main purpose of the present invention is to provide a short pipe replacement equipment for collapsed pipelines, aiming at the replacement of old and old pipelines with trenchless short pipe replacement technology The renovation of facilities lacks corresponding intelligent equipment, which leads to the problems of low construction efficiency, long construction period and high cost. A new equipment structure is proposed to meet the construction needs, which can improve the construction speed, shorten the construction period, and effectively reduce the project cost.
