Anti-seepage reinforcement device for pipeline and repairing method thereof

Abstract

The invention belongs to the technical field of a pipeline, and specifically relates to an anti-seepage reinforcement device for the pipeline and a repairing method thereof. The anti-seepage reinforcement device for the pipeline, provided by the invention, comprises a lining, the lining is arranged through being attached to an inner wall surface of a to-be-repaired pipeline in a ring-shaped form,the lining comprises a first lining plate and a second lining plate, a sealed cavity layer is arranged between the first lining plate and the second lining plate, an external surface of the first lining plate is convexly provided with a first special-shaped locating structure, the first lining plate is tightly attached onto an inner wall of the to-be-repaired pipeline through the first special-shaped locating structure, and an airtight ring-shaped tubular structure is formed, movement of the anti-seepage reinforcement device caused when air inflation and slurry injection are executed can be avoided effectively, and smoothness of the repaired pipeline is guaranteed; a ring-shaped surface of the ring-shaped tubular structure is provided with an air inlet, a slurry injection hole and an air outlet, air inlet, the slurry injection hole and the air outlet are respectively communicated with the cavity layer, and thus, pipeline repairing can be executed when water exists.

Description

technical field [0001] The invention belongs to the technical field of pipelines, and in particular relates to a pipeline anti-seepage reinforcement device and a repair method thereof. Background technique [0002] With the rapid development of urban construction, the number of underground pipelines worldwide is increasing day by day. In these pipelines that are built at different times and run day and night, problems such as damage, fouling, and corrosion often occur, which lead to a decrease in pipeline transportation capacity, and even cause leakage, explosion, blockage, ground subsidence, and "the city looks at the sea" and other incidents. It represents and tests the "conscience of the city". Usually, the repair work of the pipeline is mainly carried out through two repair methods of excavation repair and non-excavation repair. [0003] Excavation repair is to directly dig the pipeline, and then repair the pipeline to be repaired. The environmental problems and econom...

Problems solved by technology

[0005] Although the above-mentioned various repair methods for underground pipelines can achieve the effect of pipe body repair, there is still room for improvement. For example, the overturning lining method is mainly used in the structural repair of pipelines (structural repair) in the pipeline repair process. The repair means that the new lined pipe has a repair method that does not depend on the original pipe structure and independently bears the external water pressure, earth pressure and dynamic load), and the reverse lining method requires a thicker pipe in the structural repair of the pipe. The resin coating increases the strength of the repair; however, when the resin coating is thick, it is difficult to turn over and transport the repair structure using the reverse lining method, and the repair structure is prone to air bubbles, weakness and bulge during the construction process, and even some Problems such as curing of thermosetting resins occur before inversion is completed, resulting in failure to meet the requirements of air permeability resistance, water permeability resistance and mechanical properties of the composite material during inversion.
