Problems solved by technology

[0003] One is that the center of gravity of the weight deviates too much from the center of gravity of the jack, resulting in a serious inclination of the load-bearing plate. However, the existing load-bearing plate and the hydraulic device are flexibly connected. The device topples over, and the second is that although the entire measurement system can still support stably when the center of gravity of the weight deviates too much from the center of gravity of the jack, the center of gravity of the weight and the center of gravity of the jack deviate slightly, which will cause deviations in the measurement of foundation subsidence and accelerate the jack The third is that the load-bearing device does not have an indicating device that can indicate the direction of force deviation, which is not easy to observe and judge how to adjust the weight

Description

technical field [0001] The invention belongs to the technical field of building detection, in particular to a device for detecting the bearing capacity of a pile-soil composite foundation. Background technique [0002] Static pressure measurement of foundation bearing capacity is the most accurate and commonly used method for measuring foundation bearing capacity. During the implementation of the static pressure measurement method, support beams need to be set to maintain the stability of the entire measurement mechanism during the process of stacking weights. After the heavy blocks are stacked neatly, adjust the height of the jack so that both ends of the secondary beam are away from the supporting beam, so that the pressure of all the heavy blocks can be transmitted to the foundation to be measured through the jack, and then the subsidence of the foundation can be measured. During the actual operation of the secondary beam leaving the supporting beam, there may be the fol...
