Description

Technical Field

[0001] This utility model relates to the field of pile foundation testing technology, specifically a pile foundation testing device. Background Technology

[0002] In modern construction engineering, pile foundations, as a crucial foundation structure of buildings, play a vital role in transferring superstructure loads to deep, stable soil layers. Their construction quality directly impacts the safety and stability of the entire construction project. Therefore, pile foundation testing is an indispensable part of ensuring the quality of construction projects. Testing allows for the accurate assessment of key performance indicators of pile foundations, such as integrity and bearing capacity.

[0003] Currently, common methods for pile foundation testing include low-strain method, high-strain method, acoustic transmission method, and static load test method, and the corresponding testing devices also have their own characteristics.

[0004] Chinese Utility Model Patent Publication No. CN216615988U discloses a pile foundation testing device. The specification of this device states that by pushing the entire device to the testing location with a push handle, a servo motor is activated to rotate a synchronous column, which in turn rotates a synchronous gear, thereby moving a synchronous rack to adjust the position of a support plate until the support plate touches the ground and the moving mechanism lifts off the ground, thus achieving full support for the entire device. Subsequently, relevant testing work can be performed using a testing instrument and detector. This device has advantages such as ensuring stability during testing while allowing for adjustment, solving the problem of existing adjustments failing to guarantee stability during testing. However, this pile foundation testing device lacks a detachable overall frame structure. The device's structure is relatively complex, containing multiple components. If some components malfunction, the integrated frame is difficult to disassemble, requiring complete disassembly, resulting in low maintenance efficiency. Furthermore, the lack of a detachable testing instrument structure means that after multiple tests, the surface of the instrument easily accumulates mud, leading to inaccurate subsequent test data and poor practicality. Summary of the Invention

Furthermore, the fastening screws passing through the mounting base and threadedly connecting to the detector effectively enhance the connection strength between the detector and the mounting base, preventing the detector from shaking or shifting during the testing process, thereby improving the accuracy of monitoring.
