Description

Technical Field

[0001] The utility model relates to the technical field of pipeline repair, in particular to a buried pipeline trenchless repair support structure. Background Art

[0002] Municipal underground pipelines are connected by a large number of corrugated pipes to form a pipe network structure. The service life of corrugated pipes buried underground can reach more than 50 years, but due to the different buried environments, the normal use of corrugated pipes will be affected to varying degrees. On the one hand, the corrugated pipes will cause different degrees of deformation of the pipe wall as a whole due to the settlement of the road surface above the pipes; on the other hand, the joints of the buried corrugated pipes are relatively fragile. With the changes in the geological structure around the pipes caused by rainwater soaking, road transportation, etc., the connections of the corrugated pipes may separate and dislocate from each other. These situations will cause the integrity of the pipeline to be destroyed. In order to ensure that the pipeline has good airtightness and normal use of the pipeline, the pipeline needs to be repaired in time. Existing technologies use both excavation and trenchless methods to repair damaged pipelines. Excavation repair projects involve a large amount of work. Operations in urban areas not only affect road traffic, but also generate a lot of noise during the excavation process. The long construction period will affect surrounding residential areas and businesses. The slow and repeated excavation is not conducive to the later maintenance of facilities. Trenchless refers to the use of various rock and soil drilling equipment and technical means to lay, replace and repair various underground pipelines through guiding and directional drilling in the case of excavation of a very small part of the surface (generally referring to small-area excavation of the entrance and exit). New construction technology, but in the process of laying, replacing and repairing, the pipeline connection needs to be leveled and aligned to avoid affecting the subsequent reinforcement work. Therefore, we propose a buried pipeline trenchless repair support structure to solve this problem.

[0003] The buried pipeline non-excavation repair support structure disclosed in the publication number CN220037829U has the following beneficial effects: the lifting mechanism cooperates with the pulling mechanism to restrain and retain all pipe sections, reducing the possibility of dislocation or settlement; at the same time, in the event of dislocation or settlement, the pipeline can be reset as much as possible by adjusting the pulling mechanism, which is convenient for subsequent reinforcement operations.

[0004] However, the buried pipeline trenchless repair support structure has the following disadvantages: during the use of the buried pipeline trenchless repair support structure, if the original pipeline opening collapses, it is not convenient to replace the pipeline without repairing and supporting the pipe opening.
