It has a protective cavity, a transmission slide rod, a piston plate, and a slide rail. The inner wall of the protective cavity is fitted with the blasting material, and the outer wall is made of aramid fiber. The ground nail shell is detachably connected to the mounting frame. Its internal reinforcement structure, through a linkage assembly, drives a claw structure to embed into the ground, improving stability. The bottom baffle of the mounting frame is equipped with a steel mesh, and the outer side is hinged to a side plate. The side plate is linked to the transmission slide rod through an angle adaptive adjustment mechanism, allowing dynamic adjustment of the protection angle. This invention, through graded protection and deep reinforcement design, achieves interception of blasting flyrock under different working conditions, effectively ensuring the safety of pile foundation blasting operations.
