Embodiment 1

[0070] Example 1: (1), such as Figure 1 to Figure 7 An electromechanical three-position integrated foundation pile bearing capacity detection system is shown, including a reaction force system, a displacement measurement system, and a loading system. The reaction force system and the loading system are integrally connected, and the reaction force system includes an anchor pile 1, Cross beam 2, hydraulic hoop 3, support arm 4, horizontal reaction device 5, support 6, foundation pile 7, inverted hydraulic cylinder A8, located on the left and right sides of the front and rear sides of the cross beam 2 A support arm 4 is rotatably connected. The outermost end of the support arm 4 and the bottom of the center of the beam 2 are both fixed with a hydraulic cylinder A8. The ends of the hydraulic cylinder A8's ejector rod are all ball-articulated to the support 6, and the support 6 is double-pinned. The shaft 60 is movably connected with the hydraulic hoop 3; anchor piles 1 are inserte...

Embodiment 2

[0096] Example 2: Such as figure 1 , Figure 7 The illustrated support arm 4 can be extended or shortened to adapt to the pile position arrangement of the anchor pile 1 in different sites, and the anchor pile 1 around the foundation pile 7 can be better utilized, and the applicability is strong.

Embodiment 3

[0097] Example 3: Such as figure 2 As shown, when the hydraulic jack K34 is loaded to the right, there is a gap 46 between the limit nut 40 and the support vertical plate 37 on the same side, which is convenient for the loosening of the left holding plate 31 and the right holding plate 32 after the inspection is completed. It is convenient to unload the hydraulic hoop 3 as a whole. At the same time, a spring 48 is sleeved on the double pin shaft 60 between the left support vertical plate 37 and the left limit vertical plate 63, so that the left holding plate 31 and the right holding plate 32 It is easier to separate, which further facilitates the unloading of the hydraulic hoop 3 as a whole.

Abstract

The invention discloses a system and method for detecting the bearing capacity of an all-round mechanical and electrical integration foundation pile. The system comprises a counter-force system, a displacement measurement system and a loading system, and the counter-force system and the loading system are integrally connected. The counter-force system comprises an anchor pile, a cross beam, hydraulic hoops, supporting arms, a horizontal counter-force device, supporting bases, the foundation pipe and inverted hydraulic oil cylinders A, the supporting arms are horizontally and rotationally connected with the left and right sides of the front side face and the left and right sides of the rear side face of the cross beam, and the hydraulic oil cylinders A are fixed to the outermost ends of thesupporting arms and the bottom of the center of the cross beam. The ends of ejector rods of the hydraulic oil cylinders A are spherically hinged to the supporting bases, and the supporting bases aremovably connected with the hydraulic hoops through double pin shafts. The structure of the system changes a traditional monotonous and separated foundation pile detection mode, foundation pipe uplift,pressure resistance and horizontal load bearing tests are integrated for detection, tedious and heavy assembly or disassembly of detection equipment is not needed, the labor intensity is extremely low, the working efficiency is extremely high, and meanwhile, the displacement measurement precision of the foundation pile is greatly improved.

Description

Technical field [0001] The invention relates to the field of foundation pile detection, in particular to an all-round mechatronics foundation pile bearing capacity detection system and method. Background technique [0002] At present, the pile foundation is a commonly used deep foundation form, which is composed of a foundation pile and a cap connected to the pile top. Foundation piles are classified into vertical compression, vertical pullout, and horizontal load according to the load category. The testing methods for vertical compression, vertical pullout, and horizontal load bearing capacity mainly include static load test method and high strain method. Among them, static load test is recognized as the most intuitive and reliable traditional method for detecting the bearing capacity of foundation piles. [0003] The static load test system is mainly composed of reaction force system, displacement measurement system and loading system. The reaction force system is mainly compos...
