Description

[0002] The foundation bearing capacity is the core index of the safety and stability of the building, and accurate detection is the key link to ensure the engineering quality. At present, the drop hammer impact combined with the pole measurement is a common means for detecting the foundation bearing capacity. It relies on the impact force generated by the free falling of the drop hammer, and combines with the observation of the deformation of the pole to the foundation to realize the evaluation of the foundation bearing capacity.

[0003] However, in the process of using the drop hammer and the pole, one operator is often needed to hold the pole to maintain its vertical state, and another operator is responsible for lifting and releasing the drop hammer to make it fall freely. This operation mode requires high coordination between personnel. If the coordination fails, such as unstable holding of the pole or improper control of the release angle and force of the drop hammer, it is easy to cause distortion of the detection data. In addition, the coordinated operation of two people undoubtedly increases the labor cost. In the scene where the personnel allocation is limited (such as remote area construction site, small infrastructure project), the limitation of this operation mode is more prominent, and even the detection work may not be able to be carried out normally due to the shortage of manpower. At the same time, the instability of manual operation also has a negative impact on the detection efficiency and data accuracy.

[0004] For the related technology in the above, the inventor believes that there is a defect that it is not convenient to keep the pole placed stably when using the drop hammer and the pole to detect the foundation bearing capacity. Therefore, a foundation detection device is proposed to solve the above problems. CONTENT OF THE UTILITY MODEL
