Abstract

The invention discloses a composite light pile group pile bearing capacity detection device, system and method. The detection device comprises a support subsystem, a loading subsystem and a test subsystem, wherein the detection device is used for detecting a composite light pile group; the support subsystem comprises connecting steel bars, a light subbase and a bearing platform; the loading subsystem comprises a loading device, a pressure sensor, a main beam and a counter-force device; and the testing subsystem comprises a dial indicator, a horizontal grating tension sensor, a load sensor, a soil pressure box and a composite reinforcement cage dynamometer. The connecting steel bars can improve the integrity of the composite light pile and the light subbase; the bearing platform can transmit the acting force of the loading device for simulating the real load of the roadbed to the light subbase; the detection system comprises the detection device and the composite light pile group, the detection requirement of the bearing capacity of the composite light pile group can be met, the detection system can also be used for researching the stress characteristic and the deformation control effect, the light subbase can well simulate the actual engineering situation, and the engineering detection requirement is met.

Description

technical field [0001] The invention relates to the technical field of geotechnical engineering, in particular to a device, system and method for detecting the bearing capacity of composite lightweight pile groups. Background technique [0002] In recent years, with the rapid development of engineering and construction, the relationship between new (structure) buildings and existing buildings (structure) is intricate. Under the additional load of new (structure) buildings, the existing buildings (structure) may have uneven settlement, tilt instability, fracturing and crushing and other diseases, and even cause major safety accidents. [0003] In order to prevent the new (structure) building from forming additional stress on the base of the existing building (structure) and affecting the normal function of the existing building (structure), the replacement of the new building (structure) by using composite lightweight piles to replace the foundation with equal load The adver...
