Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of construction engineering equipment, in particular to a bridge pile foundation pile head chiseling and soft processing device. BACKGROUND

[0002] When cast-in-situ bored pile is poured, the pile top elevation should be 0.5-1.0m higher than the designed pile top elevation to ensure the strength of the pile body concrete. The part of the pile head higher than the designed pile top elevation must be chiseled during the subsequent construction process, and the work of chiseling this part of the pile head concrete is called "breaking pile head". At present, in the pile foundation construction of construction engineering, the breaking of the cast-in-situ bored pile head is usually carried out by manual or mechanical methods, which has the problems of long construction period, high economic cost, noise pollution, dust pollution and construction safety, etc. CN111764389A proposes a method for breaking the cast-in-situ bored pile head, which embeds a group of vertical PVC pipes in the pile head part before the initial setting of the pile body concrete. When the strength of the pile body concrete reaches more than 75%, pre-cracking slurry which will gradually expand spontaneously is poured into the PVC pipes. The pre-cracking slurry must be poured into the PVC pipes before heating. After the pouring is completed, the pipe openings of the PVC pipes are covered and sealed. The pre-cracking slurry gradually expands along the pipe body of the PVC pipe, and the expansion pressure of the pre-cracking slurry expands and cracks the PVC pipe, so that the concrete around the pipe body of the PVC pipe is expanded and cracked, and the pile head is broken and then broken.

[0003] CN108532598B proposes a concrete pile head breaking device, which comprises a machine body, a moving base and a supporting arm. The moving base is arranged at the bottom of the machine body, rollers are installed at the four corners of the bottom of the moving base, supporting arms are welded on the upper surface of the moving base, a rotating shaft is horizontally arranged at the upper part of the machine body, and the left end of the rotating shaft is rotatably connected with the left supporting arm. The right end of the rotating shaft penetrates through the right supporting arm and extends to the right side of the machine body. A first servo motor is arranged above the right side of the machine body, the right end of the rotating shaft is welded with the output shaft of the first servo motor, two first bevel gears with the same size are installed on the rotating shaft, an inner threaded pipe is vertically arranged below the rotating shaft, and a screw rod is rotatably connected with the lower end of the inner threaded pipe. Since the strength of concrete reaches 100%, high strength is required during the processing process, manual and mechanical operations are needed, and the construction cost is increased. In order to provide construction progress and reduce the construction cost of personnel and construction machinery, a bridge pile foundation pile head chiseling and soft processing device needs to be designed to complete the pile head soft processing process before the initial setting of concrete, which is of great significance to construction units.
