Falling rock depense wall with improved workability and flexural toughness

摘要

The present invention relates to a rock fracture protection device in which H-beams are erected at a predetermined interval on the ground at a construction site where rock or soil is expected to flow down, and a grating shield is inserted between the H-beams and the H-beams. The grating protection plate is a steel grating panel including a plurality of iron frames formed in a lattice shape, a rhombus shape, an oblique shape or an I shape, and a plurality of regularly arranged spaced apart from each other, and the steel grating by rock or earth and sand. It includes a reinforcing plate attached to the rear of the steel grating panel to prevent damage to the panel. According to the present invention, construction, economy, safety and flexural toughness by using a steel grating panel comprising a plurality of iron frames formed in a grid, rhombus, oblique or I-shape and a plurality of regularly arranged openings spaced apart from each other This excellent, iron plate, rubber pad or fiber sheet plate attached to the back of the steel grating panel to prevent damage to the steel grating panel and various designs can be solved to reduce the user's anxiety, improve the safety and aesthetics of the traffic. .
