Side slope anchoring structure and frame beam supporting construction method using same

Abstract

The invention relates to a side slope anchoring structure and a frame beam supporting construction method using the same. The side slope anchoring structure comprises an anchoring steel pipe and a grouting pipe arranged in the anchoring steel pipe in a penetrating mode, the grouting pipe is fixedly sleeved with two grout stopping seats, a grout outlet hole located between the two grout stopping seats is formed in the grouting pipe, a grout flowing gap is formed between the outer walls of the grout stopping seats and the inner wall of the anchoring steel pipe, plugging pieces slide in the groutstopping seats, the grouting pipe is provided with driving assemblies used for driving the plugging pieces to slide, and the plugging pieces are provided with sealing pieces. According to the side slope anchoring structure and the frame beam supporting construction method using the same, by arranging the grouting pipe, multi-section type splitting grouting can be achieved, a side slope soil bodyforms a solid body, the sliding resistance of the side slope soil body is improved, moreover, a splitting grouting body can improve the side frictional resistance of the anchoring steel pipe, and thenthe anchoring force of the anchoring steel pipe is improved; and due to the characteristic that the plugging pieces can be controlled in a sliding mode, the slurry flowing gap is controllable, the splitting grouting pressure and effect can be ensured, and the frictional resistance generated when the grouting pipe moves relative to the anchoring steel pipe and the frictional loss of the sealing pieces can be reduced.

Description

Technical field [0001] This application relates to the field of slope construction technology, and in particular to a slope anchoring structure and a frame beam support construction method using the structure. Background technique [0002] Existing construction methods for frame beams on slopes, such as the Chinese patent with the announcement number CN103924605B, discloses a frame beam ecological slope protection structure and construction method, which belong to the field of environmental protection. Including sash beams and anchor rods or anchor cables for fixing the sash beams. In the sash formed by each sash beam, the soil and grass bags are stacked to be flush with the sash beams, and there are plastic nets on the soil and grass bags. Or the metal mesh is covered and fixed on the fixed anchor rod, and the grass bag has a base layer and a surface layer. In the present invention, an anchor cable or an anchor rod and a concrete frame are first arranged on the side slope, and ...
