Description

Technical Field

[0001] The present application relates to the technical field of underground engineering construction, and in particular to a method for connecting segmented lifting joints of a steel cage. Background Art

[0002] The main function of the steel cage is the same as the stress on the longitudinal steel bars of the column. It mainly plays a tensile role. The compressive strength of concrete is high but the tensile strength is very low. It restrains the concrete of the pile body so that it can withstand a certain axial tension. The steel cage is also widely used in construction operations in many fields, such as the construction of underground continuous walls under low-headroom high-pressure corridors.

[0003] At present, during the construction of underground continuous walls under low-headroom high-voltage corridors, due to the limitation of the protection distance of the high-voltage corridors, it is necessary to split the steel cage into several sections for production. After the production is completed, the steel cage is hoisted into the slot in sections for connection. During the connection process, it is necessary to adjust each joint. During the hoisting and lowering of some joints into the well, they are misaligned due to bumps and misalignment of the upper and lower steel cages. The construction workers need to make adjustments, which leads to a long connection time between the upper and lower sections of the steel cages, increasing the risk of exposure of the underground continuous wall slot section. Summary of the invention

[0004] In order to improve the connection efficiency between segmented steel cages under low-headroom high-voltage corridors and reduce the risk of exposure of underground continuous wall groove sections, the present application provides a connection method for segmented lifting joints of steel cages.
