If the pile body is completely buried in the soil and the bottom of the cap is in contact with the soil, it is called a low cap pile foundation; if the upper part of the pile body is exposed to the ground and the bottom of the cap is above the ground, it is called a high cap pile foundation. Since the pile foundation is the basis of the building, it has very high requirements for stability, otherwise there will be engineering quality problems. The existing fixing device is not easy to disassemble and install, and it is not easy to adjust, and it cannot be used for piles of different sizes;

The beneficial effect is that the pile foundation safety fixing device for construction engineering, by setting a threaded column and a threaded barrel, by rotating the rotating plate, the first rotating shaft drives the first bevel gear, the first bevel gear drives the second bevel gear, the second bevel gear drives the second rotating shaft to rotate, the second rotating shaft drives the threaded column to rotate, and the threaded barrel is extended and retracted, so as to facilitate the adjustment of the height of the first arc-shaped fixing plate and the second arc-shaped fixing plate, and to facilitate the fixing of pile foundations of different heights;

[0004] When in use, the two sets of fixing devices are respectively arranged at different positions of the pile foundation in the above-mentioned patent. By rotating the pointed bolt, the pointed bolt is fixed to the ground inside the second movable hole, and the fixing seat is fixed. According to the different heights of the pile foundation, the rotating plate is rotated to make the first rotating shaft drive the first bevel gear, the first bevel gear drives the second bevel gear, the second bevel gear drives the second rotating shaft to rotate, and the second rotating shaft drives the threaded column to rotate, so that the slider moves in the slide groove, and the threaded cylinder is extended and retracted, and the first arc-shaped fixing plate and the second arc-shaped fixing plate are adjusted to a suitable height, so that the first arc-shaped fixing plate and the second arc-shaped fixing plate are close to each other, so that the first bolt moves in the first movable hole, and the threaded cap is tightened so that the threaded cap overlaps with the surface of the connecting plate, so that the first arc-shaped fixing plate and the second arc-shaped fixing plate are fixed to each other.

[0005] By rotating the second bolt, the second bolt moves in the threaded hole, so that the second bolt drives the arc-shaped limit plate to move, so that the two sets of arc-shaped limit plates are close to the pile foundation, and the pile foundation is fixed;

[0006] The above patent adopts an inclined hinged structure to support the pile foundation, and its bottom is supported by two sets of fixed seats. The support height is relatively large, and the stability of the bottom inserted into the ground is poor, which affects the stability and firmness of the pile foundation during piling positioning. In addition, the structure is complex, the cost is high, and the operation is complicated and inconvenient. Utility Model Content
