TECHNICAL FIELD
[0001] The utility model relates to the technical field of foundation detection, especially to a bearing capacity detection device. BACKGROUND
[0002] In the existing foundation detection, the light touch probe is an in-situ testing device for evaluating the engineering properties of foundation soil. It mainly drives a conical probe of a certain size into the soil through hammering, and judges the properties and bearing capacity of the soil according to the penetration (i.e. the degree of difficulty of the probe into the soil). Its working principle is to use the falling hammer energy to analyze the physical and mechanical properties of the soil layer by measuring the penetration depth of the probe in the soil and the number of hammering. In the static sounding test, the initial verticality of the probe rod is crucial to the accuracy of the entire test. Once the probe rod is deflected, the deflection angle will gradually accumulate with the increase of the penetration depth, and eventually may cause a large deviation of the test results. Especially in the stratum containing hard impurities such as gravel and bricks, deflection is more likely to occur, thereby seriously affecting the test results.
[0003] In the prior art, in order to ensure the verticality, the operator needs to repeatedly adjust the position and angle of the light touch probe, which reduces the test efficiency and makes the operation difficult in ensuring the verticality.
