Description

Technical Field

[0001] The utility model relates to the technical field of single pile vertical bearing capacity detection, in particular to a static pressure non-destructive quick assembly device for anchor piles. Background Art

[0002] The bearing capacity of a single pile refers to the maximum load that a structure can withstand under normal use, with the strength and stability of the foundation soil and the pile itself guaranteed and the deformation within the allowable range under the action of a single pile load. In general, piles are subject to axial force, transverse axial force and bending moment. Therefore, the axial bearing capacity and transverse axial bearing capacity of a single pile must be studied and determined separately. The bearing capacity of a pile is the result of the combined action of the pile and the soil. Understanding the basic concepts of the force transmission path between the pile and the soil under axial load, the composition characteristics of the bearing capacity of a single pile, and the stress failure form of a single pile will be instructive for correctly determining the bearing capacity of a single pile. For the detection of the vertical bearing capacity of a single pile, the main intuitive detection method is the static load method, referring to the specification "Technical Specifications for Testing of Building Foundation Pile" JGJ 106-2014, specification 4.2.2 The loading reaction device can be selected according to the site conditions, such as the anchor pile reaction device, to achieve the following solution: The vertical bearing capacity of a single pile requires a certain force for static pressure. The original anchor pile will damage the pile head and the original pile reinforcement. The current anchor pile static pressure non-destructive quick assembly device does not need to damage the pile head, which can quickly reduce the time for testing.

[0003] The above-mentioned prior art has some disadvantages: 1. It is difficult to replace the pressure block of the anchor pile static pressure lossless quick assembly device. When testing the bearing capacity of a single pile, the weight of the pressure block needs to be adjusted. When testing different single piles, different single piles need to be replaced.

[0004] 2. It is difficult to fix the pressure sensor with the static pressure non-destructive quick assembly device of the anchor pile. When testing a single pile, the pressure sensor may be offset. Utility Model Content
