Background
Screw pile is a foundation treatment technology widely applied to constructional engineering, and the design and construction quality of pile head directly affect the bearing capacity and stability of the whole pile foundation. Screw pile heads are usually referred to as the parts of the pile body top connected to the bearing platform or foundation structure, which serve to transfer the load of the superstructure to the pile body and ensure that the load is evenly distributed during construction, and handling of the pile heads is critical. Firstly, the pile head should be kept flat, so that the contact surface of the pile head and the bearing platform is tightly attached, and stress concentration caused by unevenness is avoided. Secondly, the concrete strength of the pile head must meet design requirements, and maintenance and inspection are generally required to ensure the quality of the pile head. In addition, the arrangement of pile head reinforcing steel bars also needs to meet the specification, so that the pile head reinforcing steel bars are effectively connected with the pile cap reinforcing steel bars, the pile head is usually cut and cleaned after the construction is finished, and the surface of the pile head reinforcing steel bars is ensured to be free of sundries and loose concrete. For projects requiring special geological conditions or high bearing capacity, the pile head may also need reinforcement treatment, such as adding reinforcing mesh or using high strength concrete.
In the screw pile head cutting process, when encountering pile heads with larger diameters and cutting pieces with smaller diameters, the cross section of the whole pile head cannot be covered once due to insufficient diameters of the cutting pieces, so that the pile heads can be separated only by cutting for many times, and the construction time is prolonged, and the operation difficulty and the labor cost are increased. Meanwhile, the uneven notch is easily caused by repeated cutting, even dislocation or deviation occurs, the connection quality of the pile head and the bearing platform is affected, and the stability of the whole structure is further weakened.
