Embodiment 1

[0036] refer to figure 1 and figure 2 As shown, a pipeline pressure plugging repair and multi-layer long-term anti-corrosion device provided by Embodiment 1 of the present invention includes a plugging block 1, a reinforcement layer 2, an anti-corrosion paste layer 3, a flame-retardant and anti-corrosion layer distributed sequentially from the inside to the outside. Corrosion belt layer 4, oily barrier layer 5, anti-corrosion protective cover 6 and anti-sticking and weather-resistant surface coating 7, wherein the plugging block 1 penetrates into the interior of the pipeline through the corrosion perforation damage point 8 on the pipeline 9, and the plugging block 1 includes The inner part of the pipe, the pipe wall part and the outer part of the pipe, the outer part of the pipe is larger than the inner part of the pipe, and the inner part of the pipe is larger than the pipe wall part. Fitted and fixed on the outer wall of the pipeline, the plugging block 1 is embedded in th...

Embodiment 2

[0085] Based on the same inventive concept, Embodiment 2 of the present invention provides a construction method for preparing the pipeline pressure leak plugging repair and multi-layer long-term anticorrosion device provided in Embodiment 1 above. The construction method includes:

[0086] (1) Clean the surface of the metal pipe structure in the construction area to remove oil, salt, and water, and polish it to a St2 standard or above until the surface of the metal pipe structure is free of steel thorns, attachments, oxide scales and obvious bubbling.

Abstract

The invention discloses a pipeline under-pressure leakage stoppage repairing and multi-layer long-acting anti-corrosion device and a construction method thereof and belongs to the technical field of surface engineering. A six-layer protection system including a leakage stoppage and strengthening layer, anticorrosive paste, an inflaming retarding anti-corrosion belt, an oily blocking layer, an anti-corrosion protection cover and a contamination-preventing and weather-proof face coating is adopted, due to the extremely good tracing ability of the six-layer protection system, the six-layer protection system can be tightly combined with a base material, a protection film composed of the anticorrosive paste and the inflaming retarding anti-corrosion belt and surface oxide of the base material can be subjected to complexation so as to prevent secondary corrosion, meanwhile, the erosion of a corrosive medium on the base material is isolated, sealing protection on anti-corrosion components isachieved through an external oily material insulation layer and the nonmetal protection cover, it is ensured that the anti-corrosion components are not lost, the contamination-preventing face coatingof the inflaming retarding nonmetal protection cover has prominent dirt-preventing performance and good weather-resisting performance, and a permanent outer protection function is provided for the protection cover.

Description

technical field [0001] The invention relates to the technical field of surface engineering, in particular to a pipeline pressure plugging repair and multi-layer long-acting anti-corrosion device and a construction method thereof. Background technique [0002] Urban pipelines are an important part of municipal supporting facilities, which are related to the daily life of thousands of households. During the service process of the urban pipeline network, the buried part of the pipeline mainly faces relatively serious soil corrosion, and the ground part mainly suffers from the corrosion hazards of the atmospheric environment. For the buried and ground main pipelines, most operation and management companies have adopted effective corrosion measures. Protective measures. However, people often ignore the complex corrosion problems faced by the pipeline at the transition point from below the ground to above the ground. This part of the pipeline is usually called the part of the gro...
