Description

Pile head crushing device for bored pile Technical Field The application relates to the technical field of pile foundation construction, in particular to a pile head crushing device for a bored pile. Background After the construction of the bored pile foundation is completed, the pile head part usually contains a large amount of sludge, the concrete quality is poor, crushing and dismantling are required, and an annular steel reinforcement framework is reserved and utilized for pouring the concrete column again. Conventionally, when the pile head is processed, a manual hand-held chiseling machine is adopted to chiseling the pile head about 0.5-1.0m above the ground, a great deal of time is consumed in the process, the construction is complex, the stability of the integral pile can be damaged, and great potential safety hazards are brought to the structure. In order to solve the above problems, the existing pile head crusher is generally composed of a plurality of splittable crushing modules, and the plurality of modules enclose a polygonal structure so as to adapt to pile bodies with different diameters. Each module is provided with a hydraulic cylinder to drive a crushing drill bit to crush pile head concrete. However, the existing modules are connected by adopting a fixed-length connecting structure, and the polygonal side length enclosed by the modules is not adjustable, so that the breaking position of the drill bit is limited. Because the arrangement mode and the interval difference of the reinforcing steel bars inside the piles of different specifications are large, the position of the drill bit cannot be adjusted according to the distribution of the reinforcing steel bars, and the drill bit is easy to interfere with the reinforcing steel bars in the crushing process, so that the reinforcing steel bars are bent or damaged.
