Abstract

The invention discloses a compressive pile load detection device and method. The device comprises a jack and a counterforce device, wherein the jack is arranged on the compressive pile to be detected, the upper surface of the jack contacts with the lower surface of the counterforce device; the counterforce device comprises a force transferring chuck, a force-transferring guide rod arranged on the force transferring chuck, a steel wire rope and a pile rope connecting mechanism; the upper surface of the jack contacts with the lower surface of the force transferring chuck, the steel wire rope penetrates through the force transferring chuck and the pile rope connecting mechanism along the force-transferring guide rod, the pile rope connecting mechanism is fixedly connected with auxiliary pile of the compressive pile to be detected, and the two ends of the steel wire rope are fixed together. By using the detection device exerting uplift loading evenly on the auxiliary piles surrounding the compressive pile to be detected, the mechanical parameters of the compressive pile to be detected can be detected accurately. The device of the invention has simple structure and convenient operation, and can meet the requirements of compressive pile vertical stationary load test.

Description

technical field [0001] The invention belongs to the field of static load tests of pile foundations, and in particular relates to a load detection device applied to compression piles, and also relates to a detection method of the device. Background technique [0002] With the rapid development of industry, there are more and more pile foundations bearing the upper load of buildings (structures). In engineering, piles that resist vertical compression loads through friction with the soil around the pile or pile end resistance are called compression piles. Compression piles belong to the category of engineering pile foundations, and are widely used in construction engineering, high-rise structures, compression resistance of offshore dock platforms, anchor pile foundations of various bridges, pile foundations of large dock floors and anchor pile foundations in static load test piles Wait. In engineering construction, the bearing capacity of compression piles has become a very i...
