Technical Field

[0001] The utility model relates to the technical field of detection devices, in particular to a foundation bearing capacity detection device. Background Art

[0002] The foundation refers to the expanded part of the wall or column of a house based on the foundation buried underground. The design and detection of the foundation is an important part of the work of construction engineers. The part of the building buried below the ground is called the foundation, and the soil layer that bears the load transmitted by the foundation is called the foundation. The first layer of soil under the bottom of the foundation is called the bearing layer. Therefore, the foundation is an important foundation for building construction. However, the foundation will deform under the action of load. In order to ensure the stability of the building, the bearing capacity of the foundation needs to be tested before construction. Most of the existing detection devices use operators to support the foundation bearing capacity detection equipment. However, it is difficult to control the strength of the operator's support grip, which will affect the operation of the foundation bearing capacity detection equipment, resulting in a reduction in the accuracy of the bearing capacity detection. Therefore, we propose a foundation bearing capacity detection device to solve the above problems. Utility Model Content

Finally, according to the distance between the foundation bearing capacity tester and the ground, the circular telescopic column drives the foundation bearing capacity tester to move downward along the circular telescopic sleeve by adjusting the positioning bolts until the lower end of the foundation bearing capacity tester is pressed into the ground. After confirmation, the positioning bolts pass through the circular telescopic sleeve and are positioned and connected to the circular telescopic column through the positioning holes. After the position is determined, according to the position where the hydraulic column needs to be limited, First loosen the fixing bolts and manually move the square limit sleeve along the hydraulic column to a suitable position.

Finally, according to the distance between the foundation bearing capacity detector and the ground, the circular telescopic column drives the foundation bearing capacity detector to move downward along the circular telescopic sleeve through the adjustment of the positioning bolts until the lower end of the foundation bearing capacity detector is pressed into the ground. After confirmation, The positioning bolt passes through the circular telescopic sleeve and is positioned and connected to the circular telescopic column through the positioning hole. After the position is determined, according to the position where the hydraulic column needs to be limited, first loosen the fixing bolt, and manually move the square limit sleeve along the hydraulic column to a suitable position. During this process, the rectangular telescopic plate is rotatably connected to the square limit sleeve through the first rotating shaft, and the rectangular telescopic sleeve is rotatably connected to the operating table through the second rotating shaft. At the same time, the rectangular telescopic plate moves to a suitable length along the rectangular telescopic sleeve. After confirmation, the fixing bolt passes through the rectangular telescopic sleeve and is positioned and connected to the rectangular telescopic plate through the fixing hole. After fixation, the hydraulic column can be limited to avoid the hydraulic column from tilting when moving up and down to test the foundation, which will cause errors in the test results of the bearing capacity of the foundation.

[0014] 2. After all the fixation is completed, the hydraulic column drives the pressing plate downward through the drive of the hydraulic cylinder, exerting pressure on the foundation to realize the experimental test of the soil bearing capacity at the foundation.
