Description

Technical Field

[0001] The present invention relates to the technical field of water conservancy engineering, and in particular to portable soil bearing capacity detection equipment and a detection method thereof. Background Art

[0002] There are three main methods currently used for on-site testing of physical and mechanical parameters such as soil bearing capacity: standard penetration test, heavy-duty dynamic probing test and light dynamic probing. The first two are a method for on-site determination of the bearing capacity of sand or clay foundations. It uses a certain hammer function (hammer weight 63.5kg, drop distance 76cm) to drive a certain specification of split-tube penetrator into the soil at the bottom of the borehole. According to the number of strikes required for the penetrator to enter the preset depth of the test soil, the changes in the soil layer and the engineering properties of the soil are judged. Among them, the light dynamic probing uses a certain hammer energy (hammer weight 10kg) to drive a certain specification of conical probe into the soil. According to the number of strikes required for the penetrator to enter the preset depth of the test soil, the engineering properties of the soil are determined and a comprehensive evaluation of the foundation soil is made.

[0003] However, the equipment used in existing methods is bulky, inconvenient, and has significant limitations. Furthermore, when personnel use the hammer, some of the impact force will pass through the cone probe, causing impact and noise on personnel and equipment, reducing their enthusiasm for work. The safety issues are also poor, with incidents of heavy hammers injuring people's fingers. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the present invention provides portable soil bearing capacity testing equipment and methods, addressing the issues of existing methods, such as the heavy, inconvenient, and limited equipment involved. This also prevents the impact of the cone probe from causing noise and impact on personnel and machinery when striking the foundation, thereby increasing employee motivation. Safety is also improved, preventing the possibility of fingers being injured by a heavy hammer.

[0008] Preferably, the soil bearing capacity portable testing device testing method comprises the following steps:

[0009] First, at the location of the soil to be tested, insert the fixing block into the soil to fix the shell. When encountering hard soil, you only need to rotate the fixing block to disengage it from the V-funnel, and then use the V-funnel to fix the shell.
