Description

Technical Field

[0001] The utility model relates to the technical field of grouting devices, in particular to a hollow anchor grouting device for a tunnel. Background Art

[0002] In the design of the tunnel arch, 25 hollow anchors are used with a wall thickness of 7mm and a hollow hole of 7mm. The hollow anchors are arranged along the radial direction of the tunnel, and the gaps between the anchor holes are filled with adhesive. The adhesive force is used to bond the anchors to the rock wall, thereby improving the strength of the rock mass and achieving the effect of reinforcement.

[0003] The Chinese utility model patent with application number 202022882436.1 discloses an extracorporeal grouting device for reinforcing the surrounding rock of a tunnel through a hollow grouting anchor. According to the above technical scheme, when it is found that the height of the grouting tank and the surrounding rock are not suitable when grouting starts, an external power supply is connected to the motor A to drive the grouting tank to move up and down. When it moves to the appropriate position, the connecting valve is opened, and the slurry in the injection tank is injected into the surrounding rock through the connecting pipe and the injection pipe. This is very convenient and can effectively solve the problem that the height of the grouting tank cannot be adjusted in the background technology, which is not conducive to grouting surrounding rocks of different heights.

[0004] However, in actual use, since the tunnel is arched, when reinforcing the tunnel, it is necessary to evenly insert hollow anchor rods into the tunnel and cast them. Therefore, when casting them, it is necessary to adjust the angle of the casting pipe so that it can correspond to the position of the hollow anchor rod. However, the above technical solution can only adjust the height of the casting pipe, but it is difficult to further adjust its position, and it is difficult to conveniently correspond the casting pipe to the position of the hollow anchor rod. Therefore, the casting efficiency is low and the use is not convenient.

[0005] For this purpose, a hollow anchor grouting device for a tunnel is proposed. Utility Model Content
