Description

Technical Field

[0001] The utility model relates to the technical field of pipeline protection, in particular to a pipeline anti-cracking protection device. Background Art

[0002] A construction project refers to an engineering entity formed through the construction of various types of buildings and their ancillary facilities and the installation of supporting lines, pipelines, and equipment. Among them, construction project pipelines are an indispensable part of construction projects. They undertake the important task of transporting liquids, gases, solids and other substances. Some pipelines are installed outside or in places where people frequently move around. Therefore, in order to prevent the pipelines from being damaged or ruptured, protective devices are generally installed.

[0003] At present, the common pipeline protection devices on the market are thermal insulation sleeves and protective outer pipes. The thermal insulation sleeves are PPR cotton sleeves, which are put on the pipelines to keep warm and prevent the pipelines from freezing and cracking in cold weather. The protective outer pipes have two hard outer shells that wrap the pipelines and are fixed with bolts to increase the overall strength of the pipelines, making them less likely to break when hit.

[0004] However, the thermal insulation sleeve is soft in texture, and it is difficult to activate effective buffering protection when it is hit by an external collision. Although the protective outer tube can prevent collisions, it is relatively hard as a whole and has poor fit with the pipe. Air can easily enter and oxidize the pipe, and the bolted joints are also easily oxidized, making it difficult to disassemble later.

[0005] Therefore, it is necessary to design a pipeline anti-cracking protection device to solve the problem. Utility Model Content

The airbag layer 24 is folded and contracted in the initial state. Although the gas enters and begins to expand, it is closely attached to the pipeline body 1 to prevent the outside air from entering and reduce oxidation;
