Abstract

The invention discloses a pipeline deformation non-excavation rehabilitation device and method. The rehabilitation device comprises a pipeline lining ring and a driving mechanism. The pipeline lining ring comprises multiple lining plates connected end to end and supporting fixing parts arranged on the lining plates. The pipeline lining ring can be opened from a contraction state to a supporting state. When the pipeline lining ring is in contraction state, adjacent lining plates are oppositely bent. When the pipeline lining ring is supported to be in the supporting state under the effect of a driving mechanism, the ends of the adjacent lining plates are in mutual butt connection, the supporting fixing parts on the adjacent lining plates are mutually fixed and matched, and therefore the pipeline lining ring is kept in a supporting state. By the adoption of the technical scheme, the defects such as pipeline deformation and collapsing can be rapidly repaired, and the pipeline deformation non-excavation rehabilitation device and method have the advantages that zero excavation is achieved, the construction period is short, environmental influences are low, and the cost is reasonable.

Description

technical field [0001] The invention relates to the technical field of pipeline construction, in particular to a trenchless repair device and method for pipeline deformation. Background technique [0002] The rupture, leakage and deformation of underground pipelines during use (severe deformation may cause pipeline collapse) will seriously affect the normal function of the pipeline. The traditional maintenance method is to excavate the ground and then replace or repair the pipeline . However, this construction method has a great impact on traffic, environment, and social economy, especially in bustling urban areas. In addition, excavation construction may also cause damage to above-ground and underground structures around the pipeline. [0003] In recent years, due to the advantages of less impact on social traffic, short construction period, and low environmental pollution, the non-excavation repair technology of drainage pipes has been applied more and more in the repair ...
