Counter-force device for pile foundation uplift static load test

Abstract

The invention discloses a counter-force device for a pile foundation uplift static load test, relates to a pile foundation detection device, and aims to solve the problems that in the prior art, a test device needs to be welded by workers, and time and labor are wasted. According to the technical scheme, the counter-force device is characterized by comprising a jack and two supporting cushion blocks arranged on the two sides of a pile foundation correspondingly, and further comprising a cross beam arranged on the two supporting cushion blocks and used for supporting the jack, wherein a top plate is arranged on a supporting seat of the jack, and a plurality of connecting rods are arranged on the top plate; and connecting sleeves allowing the connecting rods to be inserted are arranged on the pile foundation, and the connecting rods are connected with the connecting sleeves through fixing assemblies. In the abovementioned way, the working mode of welding can be replaced, the workload ofworkers is relieved, and the test efficiency is improved.

Description

technical field [0001] The invention relates to a pile foundation detection device, more specifically, it relates to a reaction force device used for pile foundation anti-lifting static load test. Background technique [0002] With the development of the economy, there are more and more urban constructions. Due to the limited land area of ​​the city, but the increasing population, the buildings are getting smaller and taller, and the pile foundation is the foundation of high-rise buildings. It needs to be built in the early stage of construction Detect the pile foundation to determine whether its deformation under the specified load is within the allowable range, so as to ensure the quality of various facilities built on this basis and avoid potential safety hazards. [0003] The bearing capacity and integrity of the pile foundation are mainly tested in two aspects. Generally, the methods for testing the bearing capacity of the pile foundation include static load test and hi...

AI Technical Summary

Problems solved by technology

[0005] When using the loading bracket in the prior art, it is necessary to first weld the left web and the right web and the end plate of the pipe pile, and weld the rib foot, then weld the top plate and the top rib, and then pass the steel beam through the left web and Between the right web, the top plate is lifted by a jack to complete the inspection of the pile foundation. However, in practical applications, the weld is prone to damage. Once damage occurs, workers need to weld again, which is time-consuming and laborious, and needs to be improved.
