[0002] Pile foundations are supporting components that transfer the load of the superstructure to the rock and soil foundation. To ensure project safety, load tests are usually conducted after pile foundation construction to determine whether their bearing capacity meets the design requirements. The main loading methods for load tests include the weight method, the anchor pile method, and the combined anchor pile and weight method. During the test, the above methods are used to apply loads to the top of the pile foundation, and the settlement at the top of the pile is measured at each level of loading. By analyzing the load-pile top settlement relationship curve, the magnitude of the pile foundation bearing capacity is determined.

The device includes two sets of supports 1, each with a moving mechanism 2 at its bottom. A controller 3 is located in front of the right support 1. Protective telescopic rods 4 are located on the sides of the two sets of supports 1 that are close to each other, and both sets of protective telescopic rods 4 are connected to the controller 3. Protective covers 5 are located on the sides of the two sets of protective telescopic rods 4 that are close to each other. Clamping mechanisms 6 are symmetrically located on the sides of the two sets of protective covers 5 that are close to each other. A top plate 7 is located on the top of the sides of the two sets of supports 1 that are close to each other, and a pressing mechanism 8 is located on the top plate 7.

[0025] Based on the above features, the working principle of this embodiment is as follows: the moving mechanism 2 pushes the two sets of brackets 1 to move, and moves the two sets of protective covers 5 to both sides of the foundation pile. The protective telescopic rods 4 are extended respectively, and the two sets of protective telescopic rods 4 drive the two sets of protective covers 5 to move closer to each other to block the foundation pile. The two sets of clamping mechanisms 6 are activated to clamp and fix the foundation pile, and the pressing mechanism 8 is activated to press and test the foundation pile.

[0026] Example 2, refer to Figures 1-3In this embodiment, to address the problem that existing testing devices do not shield the foundation piles, leading to pile breakage during testing and the resulting fragments potentially injuring workers, posing a safety hazard and limiting applicability, this foundation pile vertical bearing capacity testing device, based on the same concept as the first embodiment, further includes two sets of protective covers 5, each with an observation window 9 in front. Both observation windows 9 are made of tempered glass. The moving mechanism 2 includes a moving block 201, which is located at the bottom of the support 1. A moving groove 202 is formed at the bottom of the moving block 201, and a moving telescopic rod 203 is provided at the top of the inner cavity of the moving groove 202. The moving telescopic rod 203 is connected to the controller 3, and a moving sliding plate 204 is provided at the bottom of the moving telescopic rod 203. The moving sliding plate 204 is slidably connected to the bottom of the moving telescopic rod 203. The movable slide plate 204 is connected to the movable slot 202. Rollers 205 are provided on both the left and right sides of the bottom. The clamping mechanism 6 includes a clamping telescopic rod 601 and an arc plate 602.

After the two sets of rollers 205 in the two moving grooves 202 are moved, the four sets of rollers 205 cooperate to facilitate the staff to push the detection device to move. After the protective cover 5 is pushed to both sides of the foundation pile, the telescopic rod 203 is controlled to shorten. The telescopic rod 203 drives the sliding plate 204 to move upward. The sliding plate 204 drives the two sets of rollers 205 to move upward, moving the two sets of rollers 205 into the moving groove 202, thereby protecting the rollers 205.

[0028] The controller 3 controls the extension of two sets of protective telescopic rods 4, which in turn drive the two sets of protective covers 5 to move closer to each other, thus shielding the foundation pile. The controller 3 then controls the extension of two sets of clamping telescopic rods 601, which in turn drive the two sets of arc-shaped plates 602 to move closer to each other, thus clamping and fixing the foundation pile. The hydraulic press 801 is started to control the extension of the hydraulic rod 802, which drives the pressing plate 803 to move downward, pressing the foundation pile. The staff can observe the testing process through the observation window 9.
