Description

Technical Field

[0001] The invention relates to a detection device, in particular to a pull-out resistance detection device for a hydraulic pile foundation, belonging to the technical field of pull-out resistance detection. Background Art

[0002] Pile foundation is a deep foundation consisting of a pile and a pile cap connected to the top of the pile, or a single pile foundation consisting of a column connected to the pile foundation. Hydraulic pile foundation is a commonly used foundation form in water conservancy projects. It builds a connection between the foundation and the building by digging the pile body deep into the ground to enhance the bearing capacity, stability and earthquake resistance of the foundation. The pull-out capacity of the pile foundation refers to the ability of the pile foundation to resist pull-out deformation when subjected to pull-out loads. This is an important parameter in pile foundation design and is directly related to the stability and safety of the pile foundation.

[0003] The existing publication number: CN219100156U is a pile foundation pull-out detection device, including a support frame, two cross bars are fixedly connected to the support frame, a slide rail is fixedly installed on the cross bar, a slide rail is slidably connected to the slide rail, a tension cylinder is fixedly installed on the slide, the output end of the tension cylinder is cooperated with one end of the telescopic rod, the other end of the telescopic rod is cooperated with a fixed plate, four groups of clamping mechanisms are arranged on both sides of the fixed plate, and the four groups of clamping mechanisms have the same structure, including an L-shaped connecting strip, a clamping cylinder is fixedly installed on the L-shaped connecting strip, the output end of the clamping cylinder is cooperated with one end of the clamping rod, and the pile foundation to be tested does not need to be clamped and fixed manually, which reduces the difficulty of operation, saves detection time, improves the detection efficiency, and can reduce the error caused by manual clamping, has high reliability, and can further improve the detection accuracy.

[0004] The above device reduces the error of manual clamping and improves the detection efficiency. Like the existing device, it has the limitation of being used on a flat bottom. It has a better test effect on pile foundations that are perpendicular to the ground. However, in water conservancy projects, many pile foundations are set on the slope of the dam, or some pile foundations will have an angle with the ground due to external water erosion and other reasons. The existing device has poor adaptability to the test environment with a large ground slope foot angle, and the overall components of the existing device are large or small parts are assembled by bolts, making the device not flexible and convenient when it is moved.
