Embodiment

[0030] The construction steps of the mold bag concrete slope protection structure are as follows:

[0031] (1) First of all, the mold bag concrete is placed on the slope, with a distance of about 1.2m from the top of the slope, and about 0.5m from the bottom of the slope to the valley;

[0032] (2) After the mold bag concrete is filled with concrete, put the reinforcement cage on the upper part of the mold bag concrete, and then insert an appropriate length of anchoring steel bar as an anchor rod, and anchor to the road surface at least 0.5m above;

[0033](3) Put rocks of a certain particle size into the reinforcement cage and put them into the grouting pipe at the same time;

[0034] (4) Use the reinforced gabion template made in advance, and use the same concrete as the bagged concrete to grout the inside of the reinforced gabion through the grouting pipe, so that the internal blocks and the bagged concrete form a whole, and further anchor the bagged concrete slope protect...

Abstract

The invention relates to a mold bag concrete slope protecting structure and a rebar cage with an anchoring structure, and belongs to the field of geotechnical engineering. The mold bag concrete slopeprotecting structure and the rebar cage with the anchoring structure can be applied to fields such as water conservancy and hydroelectric engineering, municipal engineering and river regulation. The mold bag concrete slope protecting structure is combined with the rebar stone cage for use, the use time of mold bag concrete is prolonged, and the slope protecting ability of the mold bag concrete isenhanced. According to the mold bag concrete slope protecting structure, the mold bag concrete is fixedly arranged on a slope face of a side slope, the top of the mold bag concrete extends to the topface of the side slope, and the rebar stone cage is fixedly arranged in the position, located on the top face of the side slope, of the mold bag concrete; and the bottom of the rebar stone cage is provided with an anchor rod, and the anchor rod penetrates through the mold bag concrete and then is fixed in the side slope in an anchoring mode. The top of the rebar stone cage is provided with a grouting pipe, a whole is formed by dimension stones in the rebar stone cage and the mold bag concrete by grouting. The mold bag concrete extends from a slope foot of the side slope to a river valley, andfoot pressing is conducted by the extension part through the rebar stone cage.

Description

technical field [0001] The invention relates to a molded bag concrete slope protection structure and a steel cage with an anchoring structure, which belong to the field of geotechnical engineering and can be applied in fields such as water conservancy and hydropower engineering, municipal engineering, and river channel management. Background technique [0002] Compared with traditional masonry works, mold bag concrete slope protection has the advantages of rapid construction, cost saving, especially convenient underwater construction. Foreign bag concrete slope protection was first seen in the Canadian Toronto Waterway Test Project completed in 1969. After the 1880s, Japan's Asahi Kasei Co., Ltd. made various mold bags, also known as fabrics, with high-strength polyester 66 cloth according to the invention of the American Construction Technology Company (patented in 1960). Fab has water permeability, so that the remaining moisture in concrete can be removed in time after re...
