Description

technical field

[0001] The invention relates to the field of pile foundation detection, in particular to a centering device and a use method for installing high-strain sensors. Background technique

[0002] Pile foundation refers to the deep foundation composed of piles and pile caps connected to the top of the pile. Pile foundation is a common foundation form in bridges, wharfs, buildings and other projects. For safety reasons, the performance requirements of pile foundations are relatively high. Therefore, at the end of piling, it is necessary to carry out engineering quality inspection on the pile foundation.

[0003] The engineering quality inspection of pile foundation generally includes the inspection of the bearing capacity of single pile and pile group, the inspection of vertical compressive bearing capacity, the inspection of structural integrity, the inspection of pile-soil load sharing ratio in composite foundation, the inspection of pile body and soil stress - S...
