Description

Technical Field

[0001] The utility model belongs to the technical field of urban construction, in particular to a device for reducing axis deviation for urban underground pipeline construction. Background Art

[0002] Urban underground pipelines are an important part of urban infrastructure, with the functions of transmitting information, transporting energy and discharging waste. It is a complex system engineering, which has developed rapidly under the background of rapid development of urban modernization and informatization. At present, its role and function are becoming more and more important. If the traditional excavation construction technology is used, it will not only have a heavy economic burden, but also have adverse effects on society and the environment. The pipe jacking construction technology can effectively solve this problem.

[0003] Pipe jacking technology is often used in underground concealed projects. The complexity of concealed projects is difficult to predict. It includes the transportation of tap water, sewage treatment, gas and heating transportation, etc., which all rely on the city's underground pipe network. my country now has a large underground pipeline system. In order to avoid conflicts with existing pipelines, the buried depth of pipelines in the future will inevitably increase, which further demonstrates that pipe jacking construction has significant economic and social benefits. It is a complex system project, and due to the uneven frontal resistance of the formation and the uneven force on the tool pipe, the pipeline axis will deviate too much, resulting in the problem of pipeline bending, making the quality requirements of the project unable to meet the design requirements.

[0004] The main problems with pipe jacking technology in our country are insufficient professional talents, outdated machinery and equipment, and uneven levels of expertise among regions. Most of those currently active in the construction front are "latecomers". Some were originally civil engineering majors who switched careers, and some are from other industries. These people have relatively little professional knowledge and find it difficult to adapt to changing construction needs. Because pipe jacking technology is often used in concealed underground projects, the complexity of concealed projects is difficult to predict, and due to the uneven frontal resistance of the stratum and the uneven force on the tool pipe, the pipeline axis will deviate too much, resulting in pipeline bending, making it impossible for the quality requirements of the project to meet the design requirements.

[0005] How to solve the above-mentioned problem of excessive axis deviation and pipe bending is the object of this project. Utility Model Content
