[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0026] This utility model provides a technical solution: such as Figure 1 and Figure 2As shown in this embodiment, a static pressure pile device for foundation includes a base 1. Limiting rods 11 are fixedly connected to all four sides of the base 1. A top plate 12 is fixedly connected to the top of the limiting rods 11. Hydraulic rods 13 are provided at both ends of the top plate 12. The output end of the hydraulic rods 13 passes through the top plate 12 and is bolted to a clamping seat 14. The clamping seat 14 has mounting grooves 141 on all four sides of its inner side. Limiting plates 142 are fixedly connected to all four sides of its outer side. The inner side of the limiting plates 142 is slidably connected to the outer wall of the limiting rods 11.
[0027] like Figure 2 As shown, a pile clamping device 2 is installed on the upper end of the base 1. The pile clamping device 2 includes a hydraulic system 21, which includes a hydraulic cylinder and a hydraulic pump to provide static pressure. The control system is connected to the hydraulic system 21. The hydraulic system 21 is set inside the mounting grooves 141 at both ends. Each output end of the hydraulic system 21 is provided with a clamping plate 22. Anti-slip pads 24 are provided in the arc-shaped grooves on the opposite side of the two clamping plates 22. Sliding rods 23 are fixedly connected to the upper and lower sides inside the mounting grooves 141 at both ends. Both ends of the clamping plate 22 are slidably connected to the sliding rods 23. By installing the pile clamping device 2, the clamping plates 22 on both sides are brought closer to the pile through the hydraulic system 21 on both sides, thereby enabling the clamping and fixing of piles of various sizes. Moreover, the arc-shaped grooves on the clamping plates 22 fit the outer wall of the pile better, resulting in a better clamping and fixing effect.
[0028] like Figure 3 and Figure 4As shown, pile driving stabilizing support devices 3 are fixedly installed around the base 1. The pile driving stabilizing support device 3 includes a mounting plate 31, which is fixedly connected to the base 1. Mounting cylinders 32 are fixedly connected to the through holes of the mounting plate 31. Fixing cones 33 are fixedly connected to the bottom side of the mounting cylinders 32. Bidirectional threaded rods 34 are provided inside the mounting cylinders 32 through bearings. Sleeves 341 are threaded to the upper and lower outer walls of the bidirectional threaded rods 34.
