Foundation pile bearing capacity detection equipment

The invention relates to equipment for detecting the bearing capacity of a foundation pile, and effectively solves the problems that the test work cannot be carried out and even potential safety hazards are caused to field operators and equipment due to the fact that the pulling resistance of an anchor pile does not reach the standard when the bearing capacity of the foundation pile is tested by adopting an anchor pile method at present. According to the technical scheme for solving the problem, the device comprises a main beam, a supporting beam, an anchor pile and a bag body arranged in the anchor pile and further comprises a base plate and a transmission assembly arranged on the base plate, fluid media are conveyed into the bag body through cooperation between the transmission assembly and a fluid storage assembly, and then the pulling resistance of the anchor pile is improved; the equipment can correspondingly adjust the pulling resistance of the anchor pile according to the real-time state of the anchor
