Pile body internal force detection device

The utility model relates to the technical field of pile body internal force detection, and discloses a pile body internal force detection device which comprises a force measuring sensor and a detection block. An arc-shaped opening is formed in the detection block, a through insertion hole communicated with the arc-shaped opening is formed in the side face of the detection block, the force sensor is inserted into the insertion hole, an elastic abutting piece connected with the force sensor is installed on the detection block, and two elastic sliding pieces are installed at the bottom of the detection block. And an arc-shaped scraping block is connected between the two elastic sliding pieces. The utility model provides a pile body internal force detection device, which solves the problem that the precision of a measurement result is possibly influenced due to the fact that soil and dust are easy to adhere to a precast pile outdoors and a sensor is insufficiently contacted with an interface of the surface of a
