However, the existing protection device is not easy to replace, and the protection performance is poor, and it cannot effectively prevent the pile head from being damaged. Therefore, we propose a protection device for the pile head of the static load test of pile foundation that is easy to replace. Summary of the invention

[0003] The main purpose of the present invention is to provide a protective device for the pile head of a static load test of a pile foundation which is easy to replace. By arranging an insertion rod and a slot, it is convenient to connect the No. 1 side panel and the No. 2 side panel with the top panel, and the No. 1 side panel and the No. 2 side panel can be conveniently fixed by using buckles and blocks, so as to facilitate the installation and replacement of the No. 1 side panel and the No. 2 side panel. By arranging a tilt alarm, when the top panel tilts, the tilt alarm can detect it in time and sound a whistle to remind, so as to avoid uneven force on the pile head caused by the tilt of the top panel. By arranging a spring group and a silicone pad, the top panel can be fully compacted onto the pile head, so as to avoid uneven force on the pile head caused by the uneven top of the pile head. By arranging an electric hydraulic cylinder, the arc clamp can be pushed to clamp and fix the pile head, and the rubber wear-resistant layer can prevent the arc clamp from being worn, which can effectively solve the problems in the background technology.
