Description

Technical Field

[0001] The utility model relates to the field of steel cage connection, in particular to a quick connection device for an underground continuous wall steel cage. Background Art

[0002] An underground diaphragm wall is an underground structure used for support and waterproofing, typically made of reinforced concrete. It is widely used in projects such as foundation pits, basements, and tunnels. It utilizes continuous concrete pouring and the installation of a steel cage to provide stable structural support against soil and water pressure. The steel cage, a crucial component of an underground diaphragm wall, consists of multiple longitudinal and transverse steel bars welded together in a staggered pattern, enhancing the wall's tensile strength and overall stability. The cage's design effectively controls cracks in the wall, improves impermeability, and ensures the long-term safety of the structure.

[0003] However, most of the quick connection devices for underground continuous wall reinforcement cages currently have the following problems:

[0004] 1. In order to prevent water from penetrating into the underground continuous wall and causing corrosion at the joints, which affects the strength and effectiveness of the steel cage, the existing quick connection devices for underground continuous wall and other structures mostly use fixed sealing gaskets at the joints for sealing. If the sealing gasket needs to be replaced, it is troublesome to disassemble and replace the fixed sealing gasket.

[0005] Second, the existing quick connection device of the underground continuous wall steel cage, when connecting the steel cage, mostly uses steel wire to wrap the connection, etc., to extend the usable length. If it is affected in subsequent construction, it is more troublesome to disassemble it, which is inconvenient for convenient installation and disassembly.

[0006] Therefore, we have made improvements to this and proposed a quick connection device for underground continuous wall steel cage. Utility Model Content

[0035] Example 2:

[0036] The solution in Example 1 is further introduced below in conjunction with a specific working method, as described below:
