A pile foundation static load test system

Abstract

The invention discloses a pile foundation static load test system. The pile foundation static load test system comprises bearing walls, a jack, a counter-force frame and balancing weights. A secondary beam is fixedly connected with a bearing plate, and a plurality of containing grooves with semicircular cross sections are evenly distributed in the bearing plate in the directions where the two ends of the secondary beam are located with the jack as a center. The balancing weights include first balancing weights and second balancing weights. Each first balancing weight is of a cylindrical structure, and the radius of each first balancing weight is equal to that of each containing groove. The length of each second balancing weight and the length of the first balancing weight are the same, one side of each second balancing weight is also provided with containing grooves, the other side of each second balancing weight is provided with combination grooves perpendicular to the containing grooves, and the cross sections of the combination grooves are the same with those of the containing grooves. In the piling process of the balancing weights, the first balancing weights and the second balancing weights are alternatively piled according to the number of layers. The pile foundation static load test system can control the balance of a carrier more easily, and the test process is safer.

Description

technical field [0001] The invention relates to the technical field of pile foundation static load detection, and more specifically relates to a pile foundation static load test system. Background technique [0002] Static load test of pile foundation is an important part of engineering inspection. The most common method is the surcharge method for inspection, and the inspection results are more intuitive. [0003] The stacking method is to install a horizontal balance steel beam on the horizontal support girder, and then lay metal beams or concrete beams on the horizontal balance steel beam to form a load-bearing platform, and then stack the counterweight on the ballast load-bearing platform After the blocks form the ballast, carry out the static load detection test on the pile foundation; the difficulty in the detection test of the surcharge method in the prior art is that due to the large number of counterweights, deviations are likely to occur during the surcharge proces...

[0003] The stacking method is to install a horizontal balance steel beam on the horizontal support girder, and then lay metal beams or concrete beams on the horizontal balance steel beam to form a load-bearing platform, and then stack the counterweight on the ballast load-bearing platform After the blocks form the ballast, carry out the static load detection test on the pile foundation; the difficulty in the detection test of the surcharge method in the prior art is that due to the large number of counterweights, deviations are likely to occur during the surcharge process, which in turn causes the center of gravity of the ballast to be out of balance , not only affects the detection accuracy, but also easily causes the counterweight to slip or the ballast to collapse, and the safety is low
