The foundation bearing capacity detection device can be used to monitor and control the foundation bearing capacity during the construction process to ensure that the construction quality meets the design requirements and prevent construction quality problems caused by unstable foundations.
[0003] When the existing foundation bearing capacity detection device detects the foundation bearing capacity, the drill bit at the bottom of the probe rod is usually inserted into the soil, and then the hammer seat is hammered by the hammer block to insert the probe rod into the ground. This cycle is repeated many times to obtain the specific value of the foundation bearing capacity based on the depth of the probe rod into the soil layer.
[0004] However, in the process of the probe rod penetrating into the soil layer, due to the lack of a supporting structure, the hammering of the hammer block will cause the probe rod to tilt to varying degrees, resulting in inaccurate depth of the probe rod entering the soil layer, affecting the accuracy of the final foundation bearing capacity measurement value; in addition, the height of the hammer seat is fixed and cannot be freely adjusted according to the energy intensity of the hammering required, which is relatively inconvenient, and the depth of the probe rod penetrating into the soil layer cannot be accurately read, affecting the final test result.
