Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe column support systems, in particular to a temporary installation hoop structure of a three-section steel pipe column. Background Art

[0002] The cover-and-excavation reverse construction method is widely used as a key construction technology in underground space development projects and subway station projects, and the intermediate steel pipe column support system is a very critical process in this technology. The installation accuracy and construction quality of the steel pipe column will directly affect the effect of the vertical bearing capacity and the safety of the overall structure. The commonly used steel pipe column construction technologies in engineering include traditional manual positioning installation, vertical insertion of static pressure pipe sinking machine, and vertical insertion of hydraulic full-rotation casing machine. These common steel pipe column construction technologies mainly adopt the method of overall insertion installation, which is installed once and does not require welding. However, in actual on-site operations, due to various reasons such as complex local geological conditions and process limitations, individual or part of the piles cannot be constructed using this overall insertion method. In addition, this overall insertion method has great safety hazards during installation due to the large diameter, long length, and heavy weight of the steel pipe column.

[0003] At present, the existing technology adopts a construction method of installing the steel pipe column in three sections to solve the above problems. The upper and lower sections of the steel pipe column are relatively light in weight and can be constructed along with the structure. The middle section is welded on site later. During the later welding, a temporary clamp is added to the appropriate position of the middle section steel pipe column to firmly clamp the middle section steel pipe column. The middle section steel pipe column is then transported to the designated position by a forklift for installation. However, the existing temporary installation clamp structure generally adopts a method of screwing and fixing two clamp plates. Its structure is relatively simple. When assembling itself, it is necessary to use bolts to lock at both ends, which is troublesome to operate. More importantly, when a forklift is used to lift the temporary installation clamp structure and the middle section steel pipe column, there is no good positioning structure between the clamp and the fork of the forklift, which makes the temporary installation clamp structure and the middle section steel pipe column unstable on the forklift. Therefore, it is urgent to design a temporary installation clamp structure of a three-section steel pipe column to solve the above problems. Utility Model Content
