A non-excavation pipeline lining method pipeline repair layer connection method

Abstract

The invention discloses a non-excavation pipeline lining method pipeline repair lamination method, which comprises the following steps: (1) prefabrication of composite cloth; (2) cleaning of pipeline; (3) assembly of composite cloth; (4) heating and bonding ; (5) Check the condition of the tube. The invention discloses a non-excavation pipeline lining method pipeline repair lamination method. In terms of heating form, the invention uses the method of reserving resistance wires, and uses electric energy instead of electric energy in the trenchless pipeline lining method inner wall repair construction. The compound cloth can be heated and bonded inside; in the pipe structure, the present invention adopts the way of lamination, adopts the compound cloth with smaller width, which is convenient for transportation, can realize various shaft construction operations, and can be used according to the construction site. Real-time adjustment of the composite cloth according to the actual conditions. The invention directly uses electric energy for heating, can reduce energy consumption, does not need excavation, has little impact on the environment, does not need large-scale auxiliary equipment, has simple procedures and quick repairs.

Description

[0001] The invention relates to a method for connecting pipeline repair layers by lining method, in particular to a method for connecting pipeline repair layers by non-excavation pipeline lining method. Background technique [0002] The traditional trenchless pipeline repair technology either requires the flexibility of the composite cloth, or uses multi-level nested prefabricated pipes, which are directly stretched into pipes during construction. The former often ends up as soft sleeve pipes that lack rigidity and need to be fixed at both ends To keep it in a tubular shape, the latter seems simple, but if the repaired pipeline is too long, the operation is extremely difficult, and what is even more fatal is that the farther away from the upstream nozzle of this type of multi-level nested prefabricated pipe, the smaller the diameter of the pipeline. Contents of the invention [0003] Purpose of the invention: The present invention aims at the problem of instant pipe formation...
