Adjustable pipeline inner support reinforcing system and reinforcing method thereof

Abstract

The invention discloses an adjustable pipeline inner support reinforcing system and a reinforcing method thereof. The reinforcing system comprises at least one reinforcing circular ring support, a reinforcing circular ring support main body and an adjusting device, one end part of the main body is a constraint end, the other end part of the main body is a sliding end, and the sliding end is overlapped on the outer side of the constraint end; and the adjusting device comprises constraint end screw blocks, sliding end screw blocks and bidirectional screw rods, and two outer thread sections of each bidirectional screw rod are correspondently connected with inner threads of each group of constraint end screw block and sliding end screw block through threads. The reinforcing method thereof comprises the steps of pipeline current situation verification, designing and manufacturing of the reinforcing circular ring support, expansion of the adjusting device, fit between the adjusting device and the main body and the like. According to the adjustable pipeline inner support reinforcing system and the reinforcing method thereof, a damaged pipeline is subjected to structural non-excavation repair, and the radial tension enables the support to be tightly attached to a to-be-reinforced structure; and a new structure and an old structure cooperatively work to make up the irregular change of the section size of the damaged pipeline, the reinforcing quality is guaranteed, the repairing process is simplified, and the service life of the pipeline is prolonged.

Description

technical field [0001] The invention belongs to the field of underground pipeline reinforcement, in particular to an adjustable internal support reinforcement system and a construction method thereof. Background technique [0002] Underground pipelines are the lifeline of urban operation, but due to different economic and construction levels in different periods, the quality of underground pipelines varies greatly. With the growth of time, many underground pipelines are approaching the end of their service life, or even "overdue service". This problem is more obvious in old urban areas. In recent years, road subsidence accidents have occurred frequently, and the reasons are often caused by the leakage, damage, or even collapse of old underground pipelines. [0003] Most of the underground pipelines are located under the main traffic roads in the city, which cannot be excavated and repaired on a large scale. Therefore, trenchless repair is currently the most simple and econ...

Problems solved by technology

[0005] The purpose of the present invention is to provide an adjustable pipeline internal bracket reinforcement system and its reinforcement method, to solve the technical problem that the existing non-excavation repair of old pipelines has poor resistance to flexible repairs and cannot solve the structural damage of pipelines ; It is also necessary to solve the technical problems of large structural cross-section size and loss of more water-passing area during rigid repair, old and new structures cannot work together, and are greatly restricted by the site environment
