Abstract

The invention relates to an integrated foundation pile static load test counterforce beam. The counterforce beam comprises a beam body, the beam body is formed by welding two long beams which are symmetrically arranged and a force distribution beam which is transversely arranged, the beam body is provided with a bolt hole used for being connected with a hydraulic jack, the beam body is further provided with screw holes and technology notches which are used for being matched with stand column assemblies for in-situ verification of the jack, and a stiffening rib is arranged in the middle of theforce distribution beam; and the counterforce beam further comprises the hydraulic jack and connecting bolts, and screw holes matched with the connecting bolts are formed in the bottom of a cylinder body of the hydraulic jack. According to the integrated foundation pile static load test counterforce beam, the loading hydraulic jack and the counterforce beam are integrated into a whole and integrally assembled, disassembled and transported, and the installing technology performance of a test loading counterforce device is greatly improved; in-situ verification can be conduced on the jack by cooperating with the corresponding stand column assemblies for jack verification and a cross beam through the constructional characteristics of the beam body; and not only is the verification cost reduced, but also the using efficiency of equipment can be greatly improved.

Description

technical field [0001] The invention belongs to the technical field of static load test of foundation pile bearing capacity, and in particular relates to an integrated static load test reaction beam of foundation pile. Background technique [0002] At present, the loading equipment for the static load test of foundation piles—the hydraulic jack and the main beam in the reaction device are separated. When installing on site, the jack must be installed first, and then the main beam. Due to the strict requirements on the horizontal centering and vertical clearance between the jack and the main beam, the installation process is cumbersome. Moreover, this installation method will lead to a relatively high installation height of the entire reaction force device, which is not conducive to safety. [0003] In addition, according to the requirements of relevant specifications, as a measuring instrument, the verification period of the above-mentioned hydraulic jack is half a year. D...
