Description
Technical Field
The utility model relates to the technical field of building industry, in particular to a claw-shaped threaded body steel pile drill.
Background
With the rapid development of the new-era building industry, the development force of underground space is continuously increased, the foundation pit scale and the excavation depth are further increased, the construction difficulty of underground engineering is correspondingly increased, and the cantilever support structure form can not meet the design requirements of deep and large foundation pit support engineering. In recent years, the application of the screw thread expanded body steel pile structure in foundation pit supporting engineering is more and more, the screw thread expanded body steel pile structure is mainly formed by combining a flange plate, a screw rod, an expanded head and a pile tip, pile sinking construction is carried out by adopting a full-automatic hydraulic screwing machine, noise in the construction process is low, a high-bearing expanded head system is stable, the bearing capacity of the supporting structure can be improved by grouting for the second time, and the like, and the screw thread expanded body steel pile structure is recyclable and has lower cost compared with other supporting forms. The applicability is extremely strong in actual engineering, and the traditional screw steel pile drilling is relatively difficult according to field tests aiming at individual complex stratum conditions, so that improvement on the screw steel pile drilling is needed.
Disclosure of utility model
In order to achieve the above purpose, the present utility model provides the following technical solutions: the claw-shaped threaded steel pile drill comprises a steel pile body, wherein a spiral steel sheet is arranged on the periphery of the steel pile body, a central screw rod is fixed in the middle of the top end of the steel pile body, a reinforcing plate is fixed on one side of the central screw rod, and a plurality of steel cones are fixed on the reinforcing plate.
Preferably, the number of the steel cones is five.
Preferably, the steel cone is distributed in an arc line taking the central screw as the center.
Preferably, the height of the central screw is greater than the height of the steel cone.
Preferably, the bottom of the steel cone is cylindrical, and the top of the steel cone is conical.
The utility model relates to a claw-shaped screw body steel pile drill, wherein in the use process of the claw-shaped screw body steel pile drill, a central screw rod and a steel cone loosen a soil layer drill, and the loosened soil layer is brought out of the ground surface through a spiral steel sheet due to the rotation of the steel pile; the central screw rod of the claw-shaped threaded body steel pile drill plays a guiding role in the working process, in addition, the lateral steel of the central screw rod is tapered into a claw shape, the function of crushing a compact soil layer is achieved, surrounding soil of the pile can be cut, the surrounding soil of the pile is loose, pile sinking is facilitated, and the claw-shaped threaded body steel pile drill is particularly suitable for a viscous soil layer.
