This work aims to determine the impact of geological conditions on engineering construction, as well as to determine the most suitable construction plan and engineering design parameters. Pile foundation is a crucial part of the investigation process. It refers to a column driven or poured into the soil to bear the load of buildings or other structures, and transfer the load to the deep soil layer to increase the bearing capacity of the soil or improve the stability of the foundation.

[0003] At present, there are many types of pile foundation quality inspection devices on the market for different inspection items. Among them, most of the devices used to detect the horizontal state of the pile foundation are not convenient for quickly understanding its specific inclination angle while measuring its horizontal state. They often require the use of multiple instruments, and the operation method is cumbersome and time-consuming. In addition, some ordinary inspection devices are relatively fixed in size and have low flexibility in use. The supporting legs of the device are not easy to adjust according to the terrain conditions and the height of the pile foundation exposed to the ground. In particular, there will be many potholes at the construction site, which will cause the device to shake easily when placed or even unable to touch the ground, affecting the measurement results. Secondly, the device is also inconvenient to adjust according to the diameter of different pile foundations, which makes it difficult to measure the specific inclination angles at both ends of some pile foundations with larger diameters.

[0004] To this end, we proposed a pile foundation quality detection device to solve the above problems. Utility Model Content

Figure 1 As shown, one side of the pile foundation only needs to be attached to one side of the limit baffle 5 to be located on the same vertical line as one side of the balance plate 6, which facilitates rapid positioning of one side of the pile foundation.

[0024] Furthermore, a square groove is provided in the middle of the balance plate 6, and the width of the square groove is equal to the diameter of the extension rod 9. The extension rod 9 is slidably inserted into the square groove, and the two are closely attached to each other without leaving a gap in the middle. Figure 1 As shown, the extension rod 9 will not slide or shake easily inside the balance board 6, thereby ensuring the accuracy of the measurement result.

[0025] Further, the mobile detection frame 7 is set to a U shape, the bottom end of the mobile detection frame 7 is set to a rectangular plate, and one side of the rectangular plate is wrapped with a silicone cushion, the rectangular plate and the extension rod 9 are located on the same vertical horizontal line, the two sides of the mobile detection frame 7 are set to arc plates, and the center of the arc plate is on the same horizontal line as the center of the hinged end of the balance board 6, and a scale line is set on one side of the arc plate near the pointer 10. Figure 1 , Attachment Figure 2 and attached Figure 3 As shown, the rectangular plate can facilitate positioning of the other side of the pile foundation so that the rotation angle of the extension rod 9 can be consistent with the inclination angle of the pile foundation.

[0026] Furthermore, the two ends of the extension rod 9 pass through the interior of the balance plate 6 and extend to the interior of the arc-shaped slide groove 8.

[0028] Working principle: before use, rotate the rotating tooth 3 to move the screw rod 11 downward, and rotate the rotating tooth 3 in the opposite direction to move the screw rod 11 upward until the height of the device support component, that is, the height of the support rod 2, the height of the rubber anti-skid pad 4 and the height of the part of the screw rod 11 exposed from the support rod 2, equals the height of the pile foundation exposed from the ground. Then put the device outside the pile foundation, and make one side of the limit baffle 5 close to the outer wall of the pile foundation, and at the same time, the bottom of one end of the balance plate 6 close to the side of the limit baffle 5 and the top end of the pile foundation. If there are potholes on the ground, rotate the rotating tooth 3 appropriately to finely adjust the position of the rubber anti-skid pad 4 until the bottom end of the rubber anti-skid pad 4 is close to the ground and the device is placed without shaking significantly. Then slide the slider 13 along the inside of the limit slide groove 12 to make the slider 13 drive the mobile detection frame 7 to move until it moves. The rectangular plate at the bottom of the detection frame 7 is tightly attached to the outer wall of the other side of the pile foundation, and then the fastening screw 14 is rotated and inserted into the top of one end of the slider 13 until one end of the fastening screw 14 is tightly attached to the surface of the main frame 1. One end of the fastening screw 14 forms a large friction with the surface of the main frame 1, so that the slider 13 will not slide easily. Finally, the balance plate 6 is rotated so that the balance plate 6 naturally covers the top of the pile foundation. The inclination angle of the balance plate 6 is the inclination angle of the pile foundation, and the balance plate 6 drives the extension rod 9 to rotate synchronously, and the extension rod 9 drives the pointer 10 to rotate. The two ends of the extension rod 9 slide along the inside of the arc-shaped slide 8 until the bottom surface of the balance plate 6 fits with the top of the pile foundation and no longer rotates. The user can understand the inclination angle of the pile foundation through the specific numbers on the scale lines on both sides of the mobile detection frame 7 pointed by the pointer 10, thereby determining whether the horizontality of the pile foundation is qualified. The above is the entire working principle of the utility model.
