Reaction device for pile foundation pullout static load test

Abstract

The invention discloses a counterforce device for pile foundation anti-lifting static load test, which relates to a pile foundation detection device, and aims to solve the time-consuming and labor-intensive problem in the prior art that requires workers to weld the test device. The key points of the scheme include a jack and two supporting pads respectively arranged on both sides of the pile foundation, and a crossbeam arranged on the two supporting pads and used to support the jack. The jack bracket is provided with a top plate, and the top plate There are several connecting rods on the pile foundation, and connecting sleeves for the connecting rods to be inserted are arranged on the pile foundation, and the connecting rods and connecting sleeves are connected by fixing components; this can replace the working method of welding and reduce the workload of workers , improve test efficiency.

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...

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.
