Description

Technical Field

[0001] The present invention relates to a detection device, specifically a detection device for the uplift capacity of hydraulic pile foundations, and belongs to the technical field of uplift capacity detection. Background Art

[0002] A pile foundation is a deep foundation composed of piles and a pile cap connecting the pile tops, or a single-pile foundation connecting columns and pile foundations. A hydraulic pile foundation is a commonly used foundation form in hydraulic engineering. It builds a connection between the foundation and the building by driving the pile body deep into the ground to enhance the bearing capacity, stability, and seismic resistance of the foundation. The uplift capacity of a pile foundation refers to the ability of the pile foundation to resist uplift deformation when subjected to an uplift load. This is an important parameter in pile foundation design and is directly related to the stability and safety of the pile foundation.

[0003] There is a pile foundation uplift detection device with the existing publication number: CN219100156U, which includes a support frame. Two crossbars are fixedly connected to the support frame. Slide rails are fixedly installed on the crossbars. A sliding plate is slidably connected to the slide rails. A pulling cylinder is fixedly installed on the sliding plate. The output end of the pulling cylinder is cooperatively connected with one end of a telescopic rod. The other end of the telescopic rod is cooperatively connected with a fixing plate. Four groups of clamping mechanisms are arranged on both sides of the fixing plate, and the four groups of clamping mechanisms have the same structure, including an L-shaped connecting bar. A clamping cylinder is fixedly installed on the L-shaped connecting bar. The output end of the clamping cylinder is cooperatively connected with one end of a clamping rod. It is not necessary to manually clamp and fix the pile foundation to be tested, reducing the operation difficulty, saving the detection time, improving the detection efficiency to a certain extent, and being able to reduce the error caused by manual clamping, with relatively high reliability and further improving the detection accuracy.

[0004] The above device reduces the error of manual clamping and improves the detection efficiency. Like existing devices, it has the limitation of being used on a flat surface and has a good test effect for pile foundations perpendicular to the ground. However, in hydraulic engineering, many pile foundations are set on the slopes of dams, or some pile foundations will form an angle with the ground due to reasons such as external water flow scouring. The existing device has a poor adaptation effect for the test environment with a large ground slope angle. Moreover, the overall components of the existing device are relatively large or assembled with small parts by bolts, making the device not flexible and convenient enough for mobile use. In addition, the existing device has a poor detection effect on the uplift capacity of pile foundations after being affected by lateral thrust.

[0005] In view of this, the present invention is specifically proposed. Summary of the Invention
