[0002] High strain testing is a testing method for determining the vertical compressive bearing capacity and integrity of a single pile. During the experiment, a heavy hammer is used to impact the top of the pile, and the velocity and force time history curves at the top of the pile are measured and analyzed using wave theory.

[0003] During high strain testing, the hammer repeatedly strikes the pile top surface, causing some damage to the bottom of the hammer. This damage causes the hammer to tilt when suspended, resulting in different contact sequences between various points on the bottom of the hammer and different points on the pile top surface. Consequently, the impact force on different parts of the pile top surface varies, affecting the results of the high strain test. Utility Model Content

[0025] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0026] According to one embodiment of the present invention, in conjunction with Figure 1 As shown, the guide mechanism 1 is a four-cornered truncated pyramid structure with a smaller top and a larger bottom. The adjustment mechanism 2 is located inside the guide mechanism 1 and can move downwards along the guide mechanism 1. The adjustment mechanism 2 is connected to the guide mechanism 1 via a steel cable. The measuring mechanism 3 detects the bottom of the adjustment mechanism 2 at the bottom to determine whether the bottom of the adjustment mechanism 2 is level, and adjusts the adjustment mechanism 2 in a timely manner. When it is necessary to release the adjustment mechanism 2, it is released through the release device on the surface of the steel cable. The adjustment mechanism 2 then falls freely along the guide mechanism 1 and hammers the pile foundation to be tested, thereby obtaining the high strain test data of the pile foundation.

[0027] According to one embodiment of the present invention, in conjunction with Figure 2 As shown, the measuring mechanism 3 includes a plate 31, a transverse groove 32, an inclined groove 33, a moving rod 34, a rubber ring 35, and a measuring frame 36. The plate 31 is an inclined plate, and the transverse groove 32 and the inclined groove 33 are connected for the movement of the moving rod 34. When the moving rod 34 is in the inclined groove 33, the adjusting mechanism 2 will not contact the measuring frame 36 when it falls. When the moving rod 34 moves to the transverse groove 32, the measuring frame 36 contacts the bottom of the adjusting mechanism 2, thereby measuring the adjusting mechanism 2. The rubber ring 35 is elastically fitted onto the surface of the moving rod 34. The rubber ring 35 can move on the surface of the moving rod 34 by pushing. When it is necessary to adjust the length of the moving rod 34 extending out of the plate 31, the moving rod 34 is pushed, and the rubber ring 35 is pushed onto the moving rod 34 by the plate 31. After the surface movement and adjustment of the length of the moving rod 34 extending out of the plate 31, the rubber ring 35 is pushed to make it contact the surface of the plate 31. The moving rod 34 is restricted by the rubber ring 35, thereby maintaining the position of the measuring frame 36. The measuring frame 36 has a stepped structure. The moving rod 34 pushes the measuring frame 36 closer to the adjustment mechanism 2. Since the steps of the measuring frame 36 are connected by inclined surfaces, the measuring frame 36 is directly pushed. The bottom of the adjustment mechanism 2 moves along the inclined surface of the measuring frame 36 to different steps, thereby obtaining the relative height data of the bottom of the adjustment mechanism 2. It is then used to determine whether the bottom of the adjustment mechanism 2 is level. The measuring frame 36 is oriented at right angles, thus fitting the four corners of the adjustment mechanism 2, thereby obtaining the horizontal trend of the bottom of the adjustment mechanism 2.

[0028] According to one embodiment of the present invention, in conjunction with Figure 3As shown, the guide mechanism 1 includes a top plate 11, hooks 12, a frame 13, a guide plate 14, a center rod 15, and a mudguard 16. The top plate 11 and the mudguard 16 are respectively located at the upper and lower ends of the frame 13. The volume of the top plate 11 is smaller than that of the mudguard 16. Two hooks 12 are fixed to the surface of the top plate 11 and are located at the upper and lower ends of the top plate 11, respectively. The hook 12 located at the upper end of the top plate 11 is used to connect to a crane, thereby lifting the guide mechanism 1 as a whole. The hook 12 located at the bottom of the top plate 11 is used for... A connecting steel rope is used to connect with the adjustment structure 2. The guide plate 14 is located in the middle of the frame 13 to guide the free fall of the adjustment mechanism 2. The middle rod 15 is fixed to the surface of the frame 13. The plate 31 is fixed at the connection between the frame 13 and the middle rod 15, so that the plate 31 is located at the bottom height of the adjustment mechanism 2, which facilitates the measuring frame 36 to measure the bottom of the adjustment mechanism 2. The mudguard 16 blocks the soil inside the frame 13 to prevent dust from flying out when the adjustment mechanism 2 falls.

[0029] According to one embodiment of the present invention, in conjunction with Figure 4 As shown, the adjustment mechanism 2 includes a frame 21, a counterweight 22, a limiting groove 23, a weight 24, and a pull rod 25. The frame 21 is located at the upper end of the counterweight 22. The limiting groove 23 is provided inside the frame 21 for placing the weight 24. By changing the number of weights 24 and the position of the weights 24 inside the frame 21, the weight distribution of the frame 21 is changed, thereby making the weight of the frame 21 uneven and causing the frame 21 to tilt. This causes the counterweight 22 to tilt, correcting the situation where the bottom of the counterweight 22 is not level.

[0030] According to one embodiment of the present invention, in conjunction with Figure 5 As shown, each weight 24 has a pull rod 25 fixed to its upper end. The surface of the weight 24 is provided with a slot. Since the weight 24 is stacked in different positions, the slot position of the weight 24 is also different. This allows the weight 24 to be stacked on top of each other while the pull rod 25 passes through the weight 24 stacked on top, keeping the pull rod 25 exposed. The pull rod 25 is pulled up by the hook at the top, thereby pulling up the weight 24.

[0031] In this embodiment, the crane lifts the top plate 11 and moves the guide mechanism 1 to the pile foundation location where high strain testing is required. At this time, the weight 22 is suspended from the bottom of the top plate 11 by the hoisting rope, pushing the moving rod 34. The moving rod 34 moves in the inclined groove 33 and enters the transverse groove 32 along the inclined groove 33, changing the position of the rubber ring 35 so that the moving rod 34 can move freely in the transverse groove 33. The moving rod 34 drives the measuring frame 36 to move, and the bottom of the measuring frame 36 contacts the bottom of the weight 22. The stepped structure of the measuring frame 36 contacts the weight 22. The weight 22 moves along the inclined plane between the steps to the next step. Observe the number of steps where the measuring frame 36 at the four corners of the weight 22 contacts the weight 22 to determine whether the weight 22 is tilted. When the bottom of the weight 22 is tilted, add or remove the number of weights 24 inside the frame 21 according to the tilt direction. When it is necessary to remove the weights 24, pull the hook on the surface of the pull rod 25 upwards to pull the weights 24 out through the pull rod 25. The weight distribution of the frame 21 changes, thereby changing the weight distribution of the weight 22, so that the bottom of the weight 22 remains horizontal.

[0032] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
