Description

Technical Field

[0001] The utility model belongs to the technical field of underground power cable tunnels, in particular to a ground-connected wall steel bar skeleton hoisting device. Background Art

[0002] With the rapid advancement of urbanization, traditional overhead power lines are gradually being moved underground to improve safety and reliability and avoid interference from external factors such as weather. This has led to the emergence and rapid development of power cable tunnels. Urban environments are characterized by congested surface traffic, a crisscrossing web of underground pipelines, and a complex and ever-changing environment. Therefore, the construction of power tunnels often utilizes the pipe jacking method.

[0003] The pipe jacking method is a trenchless underground pipeline laying technology. This method pre-sets a starting well (launching well) and a receiving well on the ground, and then installs a jacking pipe or jacking equipment in the starting well to push the pipeline section or pipeline from the starting well to the receiving well. During the advancement process, the direction can be adjusted through the guidance system to ensure that the pipeline follows the predetermined trajectory. Every time the distance of one end is advanced, a new pipeline section is added to the starting well and connected to the already advanced pipeline section until the pipeline reaches the receiving well, thereby realizing the installation of the pipeline. This method can minimize the impact on ground traffic and underground facilities.

[0004] During foundation pit construction, working wells such as the starting and receiving wells used in pipe jacking construction are often enclosed by ground-connected walls to prevent rock and soil collapse. However, when the construction site is located in poor geological conditions such as silt or silt sand, the length and width of a single ground-connected wall steel frame are as long as 40m and 6m respectively. Combined with the two H-shaped steel joints on either side of the steel frame, the total weight of the steel frame is as high as 55t. During the installation process using a large-tonnage crane, if the lifting points and hangers are not properly designed, the steel frame is prone to flexural deformation. In severe cases, the steel frame welds may crack and the entire structure may fall apart. Therefore, how to effectively meet the construction challenges of installing the steel frame of large-scale and heavy-tonnage ground-connected walls and ensure safe and efficient construction is a technical problem that needs to be solved urgently.
