Anchor pile cross beam counterforce device

Abstract

The invention relates to an anchor pile cross beam counterforce device. The device comprises a jack, wherein a main beam is horizontally arranged at the top of the jack, the two ends of the main beamare horizontally provided with secondary beams perpendicular to the main beam, anchor piles pre-buried underground are arranged below the two ends of the secondary beams correspondingly, the two endsof the upper surfaces of the secondary beams are provided with upper anchorage devices corresponding to the anchor piles, lower anchorage devices corresponding to the upper anchorage devices are arranged between the secondary beams and the anchor piles, the upper anchorage devices and the lower anchorage devices are detachably connected through a plurality of steel bars correspondingly, and the lower anchorage devices are detachably connected with reinforcements on the anchor piles correspondingly. According to the device, a detachable connection structure is adopted to replace steel bar welding, the workload is reduced, the construction efficiency is improved, the universal tonnage anchor pile static load test in building construction can be met, and the practicability is high.

Description

technical field [0001] The invention relates to the technical field of pile foundation static load test, in particular to an anchor pile beam reaction device. Background technique [0002] In civil engineering, the pile foundation static load test is the basic requirement and method for the design bearing capacity and construction quality verification of the pile foundation. provide data. The basic principle of the pile foundation static load test is to load the pile foundation with weight and simulate its future working conditions to observe the settlement displacement of the top of the pile foundation after the weight is loaded over time, so as to determine the vertical compressive bearing capacity of the corresponding test pile force. [0003] The core of the pile foundation static load test is the reaction device, commonly used are the surcharge reaction device and the anchor pile reaction device, the traditional anchor pile reaction device, the reaction frame and the ...

AI Technical Summary

Problems solved by technology

[0003] The core of the pile foundation static load test is the reaction device, commonly used are the surcharge reaction device and the anchor pile reaction device, the traditional anchor pile reaction device, the reaction frame and the anchor pile are mainly welded and connected by steel bars, because The large number of steel bars leads to heavy welding workload and long working hours. A large number of waste bars are generated during the welding process, resulting in waste of materials, and the bearing capacity of traditional reaction force devices is mostly 600t~800t. For higher tonnage static load tests or For anchor piles with different diameters, it is necessary to disassemble the welded steel bars, then replace the steel bars and re-weld them, which further increases the workload and reduces work efficiency
