Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of anchor grouting, in particular to an anchor grouting support structure and method. BACKGROUND

[0002] Grouting is an important process of anchor rod and anchor cable construction. The role of grouting is to form an anchoring section, anchor the tension rod in the rock-soil layer, prevent corrosion of the steel tension rod, fill the cracks of the rock layer and the pores of the soil layer. The anchor rod is the most basic component of the roadway support in the current coal mine, which reinforces the surrounding rock of the roadway together, so that the surrounding rock supports itself. Anchor rods are not only used in mines, but also in engineering technology to reinforce the main body of slopes, tunnels and dam bodies. As a tension member that penetrates into the stratum, one end of the anchor rod is connected with the engineering structure, and the other end penetrates into the stratum. The whole anchor rod is divided into a free section and an anchoring section. The free section refers to the area that transmits the tension at the anchor rod head to the anchoring body. Its function is to apply pre-stress to the anchor rod.

[0003] For example, the publication number is CN110985066A (named a tunnel grouting support method and structure). The method is to inject concrete slurry into the tunnel pre-support top and both sides by using a pipe shed grouting pipe, so that the surrounding rock of the tunnel pre-support top and both sides is connected into an integral structure by the concrete slurry, forming a protective shell for the tunnel pre-support. At the same time, the pipe shed grouting pipe is used to inject concrete slurry into the surrounding rock farther away from the tunnel pre-support top and both sides, so that the surrounding rock farther away from the tunnel pre-support top and both sides also forms an integral structure, thereby improving the self-supporting capacity of the surrounding rock farther away from the tunnel pre-support top and both sides and reducing the risk of collapse. The pipe shed grouting pipe and the anchoring grouting pipe are both tubular structures with one end closed and the other end open. The closed end is a conical pointed structure to reduce the insertion resistance. The pipe wall of the pipe shed grouting pipe and the anchoring grouting pipe is provided with evenly distributed grouting holes in the shape of a plum blossom to improve the uniformity of grouting. Steel cages are arranged in the pipe shed grouting pipe and the anchoring grouting pipe to enhance the toughness and anti-deformation capacity of the pipe shed grouting pipe and the anchoring grouting pipe. The anchoring grouting pipe is controlled in the insertion direction by a guide plate. The guide plate is provided with a plurality of pairs of inclined guide holes. All the inclined guide holes are inclined upward from the tunnel mouth. Each pair of inclined guide holes is inclined in opposite directions to form a scissors fork structure. However, the two inclined guide holes in one pair of inclined guide holes are spaced apart along the length direction of the tunnel, and the center lines of the two inclined guide holes do not intersect in space.

[0004] The above-mentioned grouting support structure anchor rod is directly inclined and placed. There is a lack of effective support structure for the inclined placement of the anchor rod, which makes it difficult to ensure that the anchor rod will not deviate during grouting, resulting in poor grouting accuracy. Therefore, we provide an anchor grouting support structure and method. SUMMARY
