Problems solved by technology

However, the above scheme can only obtain accurate horizontal bearing capacity data when the pile remains vertical in the permafrost area. When the pile tilts or twists in the permafrost area, the accurate horizontal bearing capacity cannot be measured.

Embodiment Construction

[0024] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0025] Such as figure 1 , Figure 4 As shown, a foundation pile horizontal bearing capacity test device includes a horizontal thrust loading device 10, and the two ends of the horizontal thrust loading device 10 are respectively provided with a ball joint mechanism 20 that can act on the test pile 100. The spherical hinge mechanism 20 can make the direction of the force generated by the horizontal thrust loading device 10 always be in the horizontal direction and pass through the axis of the test pile 100, and can keep the position of the force application point of the horizontal thrust loading device 10 on the test pile 100 all the time.

[0026] Such as Figure 4 As shown, when the spherical hinge mechanism 20 acts on the test pile 100, the force generated by the horizontal thrust loading device 10 is always at the level, and the ...

Abstract

The invention belongs to the technical field of building detection equipment and relates to a tester for a foundation pile horizontal bearing capacity. The tester for the foundation pile horizontal bearing capacity comprises a horizontal thrust loading device; one ball hinge mechanism capable of acting on a trial pile is arranged at each of two ends of the horizontal thrust loading device; an action force generated by the horizontal thrust loading device can be always positioned in the horizontal direction and pass the axis of the trial pile due to the ball hinge mechanisms, and the position of the stress point of the horizontal thrust loading device for the trial pile is always kept unchanged. The tester for the foundation pile horizontal bearing capacity has the advantages that the horizontal bearing capacity can be accurately obtained no matter the trial pile is vertical or not and the like.

Description

technical field [0001] The invention belongs to the technical field of building detection equipment, and relates to a test device for the horizontal bearing capacity of foundation piles. Background technique [0002] At present, the method of triangular pile arrangement is adopted in engineering, that is, the pile at one vertex is the test pile, and the piles at the other two vertices are reaction piles. This will cause a large displacement of the two reaction piles, making the test The horizontal bearing capacity of the pile is quite different from the actual horizontal bearing capacity, and the test results cannot be directly used in the design of the pile foundation. In addition, because no active measures are taken to protect the top of the test pile, the point where the horizontal pressure of the test pile is easily damaged crushed, resulting in the failure of the horizontal bearing capacity test. [0003] After continuous exploration, various solutions have been propo...
