Description

Reinforced Hoisting Structure of Reinforcement Cage Connected to Wall of Deep Foundation Pit

technical field

The utility model relates to the field of construction, in particular to a reinforcing and hoisting structure for a deep foundation pit connecting wall reinforcement cage.

Background technique

There are three methods for hoisting the reinforcement cage connected to the wall of the deep foundation pit. The first method divides the reinforcement cages of the connecting walls of deep foundation pits into multi-layer installations, and uses the pole beams to clamp the reinforcing cages of connecting walls of deep foundation pits. Until the installation of the reinforcement cage for the connecting wall of the deep foundation pit is completed; the second method is to complete the installation on the ground tire, and then the reinforcing cage for the connecting wall of the deep foundation pit is hoisted in place and lowered as a whole; the third method is to use the auxiliary crane and the main crane For lifting, keep the height of the pulley of the auxiliary crane unchanged, lift the pulley of the main crane, and turn over the reinforcement cage on the wall of the deep foundation pit until the reinforcement is set vertically.

When the first method is used to hoist the reinforcement cage for the ground connection wall of the deep foundation pit, the installation time of the reinforcement cage for the connection wall of the deep foundation pit is too long, which increases the risk of hole collapse, and the construction is slow, which affects the progress; After installing the reinforcement cage for the deep foundation pit wall on the tire, and then lowering the reinforcement cage for the deep foundation pit wall as a whole, it is easy to cause the deformation of the reinforcement cage for the connection wall of the deep foundation pit and cannot be lowered, which will affect the construction of the connection wall of the deep foundation pit Quality: When the third hoisting method is adopted, the hoisting is prone to large deflection deformation, which will crack the weld seam and the whole frame will fall apart, which will cause great safety hazards. In addition, the hoisting point is not clear and the force is uneven. When the beam directly bears the reinforcement cage of the connecting wall of the deep foundation pit, it will deform the steel bar and affect the quality of the reinforcing cage of the connecting wall of the deep foundation pit.
