Detailed Description
Referring to fig. 1, 2 and 3, the utility model provides a falling prevention device for installing a bridge hole pile cage, which comprises a base 1, wherein the base 1 is integrally in a cylindrical shape with an upper opening and a lower opening; a pin hole 3 is arranged on the side wall of the base 1; the pin hole 3 is internally provided with an anti-falling bolt 2.
Wherein, prevent weighing down 2 at least, 2 prevent weighing down bolt 2 through pinhole 3 symmetry settings on the lateral wall of base 1. The anti-falling bolt 2 comprises a bolt rod and an anti-falling head arranged at the end part of the bolt rod; the area enclosed by the outer contour of the anti-turning round is larger than the cross-sectional area of the pin rod. The anti-falling bolt 2 is a solid steel bar.
The base 1 adopted by the utility model comprises an inner side base, and the side wall of the inner side base is provided with a pin hole 3.
