Pit bottom anti-uplift anchoring device

The utility model relates to a pit bottom anti-uplift anchoring and pulling device, which belongs to the field of protection devices of foundations or foundation structures, and comprises an anchor pile, the anchor pile is slidably connected with a restraint plate for restraining a soil body, the anchor pile and the restraint plate form a door-type structure, and the restraint plate is provided with a locking structure. By arranging the restraining plate in sliding connection on the anchor pile and then using the locking structure to lock the restraining plate, the technical effect that the restraining plate gradually descends along with the foundation pit construction progress and reinforces the soil body at any time is achieved, and the technical effect that the influence on soil body upheaval in the non-construction time period is further reduced is further achieved; and the beneficial effect that the construction period arrangement of foundation pit excavation is wider and more flexible is further achieve
