IF THE SLOPE OF THE ROAD WHERE THE SHOCK ABSORPTION IS POSSIBLE THE FALLING ROCK PREVENTION RAILING

摘要

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slope fall prevention measure of a road surface capable of absorbing shock, which is used to prevent damage to a traffic vehicle or traffic accident caused by a rockfall occurring at a slope formed at an edge of a road, and includes a wire insertion hole 32 formed in a post 30. Install the steel wire guide bushing 50 for guiding the twisted steel wire 40, and the bolt sleeve 62 screwed with the preload nut 60 and the lock nut 61 on both ends of the twisted steel wire 40 The compression spring 64, which is compressed and has an elastic restoring force in the direction in which the twisted steel wire 40 is tensioned, is installed to rebound between the preload nut 60 and the post 30, and is concentric in the outer side of the buffer spring 64. A shock absorbing corrugation pipe 70 is formed between the preload nut 60 and the post 30, but the auxiliary spring 72 having a weaker elasticity than the shock absorbing spring 64 has a length of the shock absorbing corrugation pipe 70. In the direction of the preload nut (60) Between the posts 30 to form a buffer section (S1) by the shock absorbing spring 64 and the shock absorption section (S2) by the shock absorbing wrinkle pipe 70, the wire mesh 34 in the middle of the twisted steel wire (40) It is configured by installing a rotary ring 74 in contact with the cloud.;Road, fall-resistant, post, buffer spring, steel wire, wire, shock absorption, pleat pipe, ring
