Road slope protecting structure and construction method thereof

Abstract

The invention discloses a road slope protecting structure. The road slope protecting structure comprises an anchoring cable, an outer layer of FRP (Fiber Reinforce Plastic) frame grid beam template and an inner reinforcing steel bar concrete frame grid beam, wherein the outer layer of FRP frame grid beam template comprises a cross beam template which is horizontally arranged and a longitudinal beam template which is arranged along a slope in the height direction of the side slope; and the inner reinforcing steel bar concrete frame grid beam comprises reinforcing steel bar concrete cross beams and reinforcing steel bar concrete longitudinal beams which are respectively cast in the cross beam template and the longitudinal beam template. Both the reinforcing steel bar concrete cross beams and the reinforcing steel bar concrete longitudinal beams are wrapped in the outer layer of FRP frame grid beam template to form a combined structure of an FRP structure and a reinforcing steel bar concrete structure, so that the exposed areas of the reinforcing steel bar concrete cross beams and the reinforcing steel bar concrete longitudinal beams are effectively reduced, the cross beams and the longitudinal beams are effectively prevented from being cracked, the service life of the road slope protecting structure is prolonged, and meanwhile, the cost of a large number of steel templates or wood templates and brackets is saved. The invention also discloses a construction method of the road slope protecting structure.

Description

technical field [0001] The invention relates to the technical field of civil engineering highways, in particular to a highway slope protection structure and a construction method thereof. Background technique [0002] Anchor cable frame beam is the slope protection structure widely used in highway high slopes, and it is usually constructed by pouring concrete on site with brackets. [0003] Please refer to figure 1 with figure 2 , figure 1 It is a schematic side view of the anchor cable frame beam structure in the prior art, figure 2 It is the facade layout diagram of the anchor cable sash beam of the prior art. The sash beams include horizontally arranged beams 01 and longitudinal beams 02 arranged obliquely and along the slope along the height direction of the slope. Lattice on concrete surface. The sash beams are reinforced concrete structures. The distance between two adjacent beams 01 and two adjacent longitudinal beams 02 is generally about 3 meters. [0004]...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a road slope protection structure, to avoid the problem that the concrete structure in the current anchor cable frame structure is directly exposed to the external environment and the concrete is easy to crack, and to improve the service life of the road slope protection structure
