Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of pile foundation bearing capacity detection, and specifically provides a pile foundation bearing capacity detection device. Background Technique
[0002] In the field of construction engineering, pile foundation bearing capacity detection is a crucial task. Its purpose is to determine the bearing capacity of the pile foundation when bearing the load of the upper structure, so as to evaluate whether the pile foundation meets the design requirements and ensure the structural safety and stability of the building. Pile foundation bearing capacity detection is usually completed with the help of professional detection devices. By applying load to the pile foundation and monitoring parameters such as its deformation and stress, the bearing capacity of the pile foundation can be analyzed and obtained.
[0003] During the pile foundation bearing capacity detection process, fixing the detection device to the pile foundation is a key link. This is because the detection device needs to act stably on the pile foundation to accurately obtain various data during the stress process of the pile foundation. If the detection device cannot maintain a stable connection with the pile foundation, the device may displace or shake during the application of load, which will cause deviations in the detection data, seriously affecting the accuracy of the detection results, and thus unable to provide a reliable basis for the quality assessment of the pile foundation and the structural design of the building. Currently, some detection devices use a simple socket connection method to fix the pile foundation. This fixing method requires that the size specifications of the pile foundation be strictly consistent with the detection positioning sleeve. Only when the pile foundation can just be inserted into the positioning sleeve can the fixing be achieved. However, in actual projects, the lengths and diameters of different pile foundations vary and the specifications are not unified. This leads to poor applicability when using the socket fixing method. When the size of the pile foundation does not match the positioning sleeve, either the pile foundation cannot be smoothly inserted into the positioning sleeve, making the detection device unable to be installed; or even if it is barely inserted, the fixing will be unstable due to size differences and it is easy to loosen during the detection process, which will also have an adverse impact on the detection results. For this reason, we propose a pile foundation bearing capacity detection device. Summary of the Invention

[0021] The clamping assembly 2 includes a connecting block 21. The lower end of the connecting block 21 contacts the upper end of the pile foundation body 1. A bidirectional screw 22 is rotatably connected to the middle of the connecting block 21. Clamping assemblies 23 are symmetrically and slidably connected to the connecting block 21. The bidirectional screw 22 is threadedly connected to the two clamping assemblies 23. A driving assembly 24 is arranged on one side of the connecting block 21. The driving assembly 24 is used to drive the bidirectional screw 22 to rotate. The driving assembly 24 includes a connecting platform 241 fixedly connected to the connecting block 21. A worm gear 242 is rotatably connected to the side of the connecting platform 241 away from the connecting block 21. The inner cavity of the worm gear 242 is fixedly connected to the bidirectional screw 22. The upper part of the outer surface of the worm gear 242 is meshed with a worm 244. A non-slip cover 243 is fixedly connected to the side of the connecting block 21 close to the connecting platform 241. The worm gear 242 is located inside the non-slip cover 243. The worm 244 is rotatably connected to the non-slip cover 243. A handle 245 is fixedly connected to one side of the worm 244. The handle 245 is made of rubber material. A number of anti-slip grooves are annularly arranged on the outer surface of the handle 245. The clamping assembly 23 includes an L-shaped plate 231 threadedly connected to the bidirectional screw 22. Limit blocks 232 are symmetrically and fixedly connected to the L-shaped plate 231.

The limit block 232 is T-shaped and is slidably connected to the connecting block 21; The support assembly 4 includes a connecting plate 42 fixedly connected to the connecting block 21. A number of connecting rods 43 are symmetrically and slidably connected to the connecting plate 42. A cross plate 41 is fixedly connected to the lower ends of the number of connecting rods 43. Support feet one 45 are symmetrically and threadedly connected to the lower part of the cross plate 41. An extension assembly 46 is fixedly arranged on the side of the cross plate 41 close to the support plate 5. The extension assembly 46 includes a docking block one 461 fixedly connected to the cross plate 41. A docking block two 462 is slidably connected to the inner cavity of the docking block one 461. A number of limit holes one 463 are arranged in the middle of the docking block one 461. A number of limit holes two 464 are arranged in the middle of the docking block two 462. The side of the docking block two 462 away from the cross plate 41 is fixedly connected to the support plate 5. A spring 44 is sleeved on the outer surface of the connecting rod 43. The two sides of the spring 44 are fixedly connected to the opposite surfaces of the connecting plate 42 and the cross plate 41.
[0022] When it is necessary to detect the pile basic body 1, first, level the land around the pile basic body 1, and then place the device around the pile basic body 1. Place the lower end of the connecting block 21 on the upper end of the pile basic body 1, and then the worker rotates by operating the handle 245. The handle 245 drives the worm 244 to rotate. Then, the worm 244 makes a meshing movement with the adjacent worm wheel 242, and then drives the worm wheel 242 to rotate. Since the worm wheel 242 is fixedly connected to the bidirectional screw 22, when the worm wheel 242 rotates, it will drive the bidirectional screw 22 to rotate. Since the bidirectional screw 22 is threadedly connected to the L-shaped plate 231, when the bidirectional screw 22 rotates, it will drive the L-shaped plate 231 to move towards the pile basic body 1, and then drive the limiting block 232 to move towards the pile basic body 1 in the inner cavity of the connecting block 21, and then drive the clamping plate 233 to move towards the pile basic body 1. Then, with the cooperation of the two clamping plates 233, the pile basic body 1 can be clamped, thereby improving the stability of the device; To improve the stability and load-bearing capacity of the device, by applying a force to the second docking block 462, drive the second docking block 462 to slide in the inner cavity of the first docking block 461, and then the distance between the support plate 5 and the cross plate 41 can be adjusted. When the distance between the support plate 5 and the cross plate 41 is determined, pass the bolt through the inner cavity of the second limiting hole 464 and the adjacent first limiting hole 463 in sequence, and then with the cooperation of the bolt and the nut, the position of the second docking block 462 in the inner cavity of the first docking block 461 can be limited. Then, it is necessary to level the end face of the cross plate 41. By operating the second support leg 6 to rotate and the first support leg 45 to rotate, the end face of the cross plate 41 can be leveled. Then place the jack 3 on the end face of the connecting block 21, and then place the support frame around the device. Use the support frame to support the steel beam and the counterweight block, and then connect the detection device to the jack 3, so that the pile basic body 1 can be detected. During the detection process, when the pile basic body 1 sinks, it will drive the clamping assembly 2 to displace together, and then drive the connecting plate 42 to move. Then the connecting plate 42 will drive the spring 44 to contract. Different impact forces result in different degrees of subsidence and settlement of the pile basic body 1, and also correspond to different contraction amounts of the spring 44. Thus, the detection of the bearing capacity of the foundation pile can be realized, and then by comparing with the detection device, the detection accuracy of the pile basic body 1 can be improved. Embodiment
[0023] The clamping plate 233 is set to be arc-shaped, and a number of grooves are opened in the inner cavity of the clamping plate 233.
[0024] By setting the splint 233 to be arc-shaped, the inner cavity of the splint 233 can be made to fit more closely to the surface of the pile base body 1. By providing a number of grooves in the inner cavity of the splint 233, the friction of the splint 233 can be increased, thereby enhancing the stability of the splint 233 during the clamping of the pile base body 1.
