Description

Technical Field

[0001] The utility model relates to the technical field of static load test auxiliary equipment, in particular to a measurement auxiliary equipment for static load test of foundation. Background Technique

[0002] The static load test of foundation is a field test method used to evaluate the bearing capacity of foundation or pile foundation. In this test, axial pressure, axial uplift force or horizontal force is gradually applied to the top of the pile or the foundation, and the corresponding settlement, uplift displacement or horizontal displacement is observed, so as to determine the characteristic value of the bearing capacity of the foundation or pile foundation. Because the static load test of foundation can directly reflect the bearing capacity of the foundation or pile foundation under actual load, it is considered a direct and reliable method to obtain these data. Through this test, engineers can more accurately predict the performance of the structure during long-term use, thus ensuring the safety and stability of the structure.

[0003] After retrieval, the Chinese patent application number is: CN201920724622.7, which discloses a jack combination support for pile foundation static load test, relating to the technical field of foundation inspection. It includes a pile head, and a plurality of jacks are carried above the pile head. A load-bearing platform is carried on the tops of the plurality of jacks, and a number of counterweight blocks are carried on the load-bearing platform. A combination frame is arranged between the pile head and the plurality of jacks. The combination frame includes a bearing plate, and the plurality of jacks are placed on the bearing plate. A connection component is arranged between the plurality of jacks and the bearing plate; the bearing plate is connected with a base, and a plurality of extension plates are arranged at a position of the base close to the auxiliary plate. The plurality of extension plates abut against the top end of the pile head, and a telescopic driving component is arranged between the plurality of extension plates and the bearing plate, and the telescopic driving component is used for the plurality of extension plates to approach or move away from each other. The utility model achieves the effect of improving the uniform stress degree of the pile head when using a plurality of jacks to pressurize the pile head.

[0004] In the above technical solution, the counterweight blocks are stacked and placed on the load-bearing platform, lacking positioning and protection functions. Once the foundation deforms, it is easy to cause the collapse of the counterweight blocks and cause injury accidents. Therefore, we need to propose a measurement auxiliary equipment for static load test of foundation. Content of the Utility Model
