Abstract

The utility model discloses a steel pile casing capable of being hoisted, which is applied to the technical field of steel pile casings and comprises a steel casing main body, wherein L-shaped sliding grooves are formed in two sides of the inside of the steel casing main body, a hoisting rod is arranged in the steel casing main body, and a hoisting hole is formed in the top of the hoisting rod. The two ends of the lifting rod slide into the L-shaped chute, so that the steel casing main body can be driven to move upwards to be lifted through the lifting rod. The pile foundation steel pile casing is convenient to install, and meanwhile the hoisting rod can be detached without affecting the drilling of pile holes in the steel pile casing main body, and can be installed on the pile foundation steel pile casing for use. The pile foundation steel pile casing is buried into the pile hole surface for supporting, and then the rotating rod is rotated out of the fixing block, so that the supporting block can support the steel pile casing main body. Therefore, the risk that the pile foundation steel casing sags in the pile hole can be reduced, and the pile foundation steel casing can be conveniently taken out subsequently.

Description

Pile foundation steel pile casing capable of being hoisted Technical Field The utility model belongs to the technical field of pile foundation steel casings, and particularly relates to a pile foundation steel casing capable of being hoisted. Background The pile foundation steel pile casing is a temporary supporting structure used in pile foundation construction, and is mainly used for protecting the hole wall, preventing hole collapse and ensuring the forming and construction safety of pile holes. At present, the Chinese utility model with the bulletin number of CN220503888U discloses a steel pile foundation pile casing capable of being hoisted. The existing pile foundation steel pile casing is generally processed into prefabricated parts according to the pile hole length, so that the pile foundation steel pile casing is low in practicality, and can not be freely assembled according to the pile hole length, so that the actual use requirements can not be met. And because the pile foundation steel pile casing is generally cylindrical, both the surface and the inner wall are very smooth, the pile foundation steel pile casing is inconvenient to hoist, and when the hoisting rope is sleeved on the surface of the pile foundation steel pile casing, the pile foundation steel pile casing is very easy to slip off, and the potential safety hazard is large. And the pile foundation steel pile casing with a smoother surface is in a soil layer which is lack of support and easy to naturally sink when being buried in a pile hole, so that the supporting effect on the pile hole is not only influenced, but also the pile foundation steel pile casing is inconvenient to take out subsequently. Disclosure of utility model The utility model aims to provide a steel pile casing capable of being hoisted, which has the advantages of being convenient for hoisting the steel pile casing, reducing the sinking risk of the steel pile casing in a pile hole and being capable of assembling and adjusting the length of the steel pile casing according to the depth of the pile hole. The technical aim of the utility model is achieved through the following technical scheme that the steel pile foundation pile casing capable of being hoisted comprises a steel casing main body, wherein L-shaped sliding grooves are formed in two sides of the inside of the steel casing main body, a hoisting rod is arranged in the steel casing main body, a hoisting hole is formed in the top of the hoisting rod, and two ends of the hoisting rod are connected with the inner surface of the steel casing main body in a sliding mode through the L-shaped sliding grooves. By adopting the technical scheme, the two ends of the lifting rod slide into the L-shaped chute, so that the steel casing main body can be driven to move upwards to lift by the lifting rod. The pile foundation steel pile casing is convenient to install, and meanwhile the hoisting rod can be detached without affecting the drilling of pile holes in the steel pile casing main body, and can be installed on the pile foundation steel pile casing for use. The pile foundation steel pile casing is buried into the pile hole surface for supporting, and then the rotating rod is rotated out of the fixing block, so that the supporting block can support the steel pile casing main body. Therefore, the risk that the pile foundation steel casing sags in the pile hole can be reduced, and the pile foundation steel casing can be conveniently taken out subsequently. The extension cylinder is spliced at the bottom of the steel pile casing main body, so that the length of the pile foundation steel pile casing can be adjusted according to the depth of the pile hole, the supporting effect of the pile hole is guaranteed, and the practicability of the pile foundation steel pile casing is improved. The steel casing is characterized in that a fixed block is welded on the surface of the top of the steel casing body, a rotating rod is rotatably connected inside the fixed block, a threaded shaft is connected inside the rotating rod in a threaded mode, and a supporting block is welded at the bottom of the threaded shaft. By adopting the technical scheme, the risk that the pile foundation steel casing sags in the pile hole can be reduced, and the pile foundation steel casing can be conveniently taken out subsequently.
