Description

Technical Field

[0001] The utility model relates to the technical field of pipe jacking construction, in particular to a large-diameter pipe jacking construction guide structure. Background Art

[0002] The pipe jacking method of construction is to use the jacking force generated by the jacking equipment in the working pit to overcome the friction between the pipe and the surrounding soil, push the pipe into the soil according to the designed slope, and transport the soil away. After one section of the pipe is pushed into the soil layer, the second section of the pipe is pushed in to complete the construction and placement of the pipe jacking.

[0003] After searching, the application with patent number CN211520379U discloses a large-diameter jacking pipe construction guide structure, including a cylindrical pipe, a mounting part arranged at the center of the pipe, and six connecting parts welded to the outer wall of the mounting part to protect the pipe from deformation during transportation. The angle between two adjacent connecting parts and the center point of the mounting part is sixty degrees. The staff can adjust the anti-deformation device according to their own needs, and the anti-deformation device is reusable and can be adjusted according to the diameter of the pipe, which brings convenience to the staff.

[0004] However, due to the setting of the pipeline, when the jacking pipe is constructed and installed, the front of the jacking pipe rubs against the soil and rocks, and the jacking pipe is easily offset under the action of external force, which causes the position of the jacking pipe construction to change and the effect of the jacking pipe construction to be poor. At the same time, during the construction of the jacking pipe, the left and right sides of the jacking pipe are respectively squeezed by the machine head and the jacking device, which makes the two sides of the jacking pipe prone to deformation and cracking.

[0005] Therefore, we proposed a guiding structure for large-diameter pipe jacking construction. Utility Model Content
