[0002] After the tunnel chamber is excavated, the original surrounding rock balance is broken, and the surrounding surrounding rock and arch are plastically deformed and relaxed. In order to prevent excessive displacement and deformation of the disturbed surrounding rock, a reasonable support structure must be used to withstand the pressure of the surrounding rock. The steel arch frame is an important component of the initial support structure of the soft surrounding rock tunnel, and is also a part of the permanent support. The steel arch frame itself has greater rigidity and strong bearing capacity. It can effectively control the deformation and displacement of the surrounding rock before the shotcrete reaches the required strength, bear the formation pressure and constrain deformation.

The utility model can adapt to the installation of the L-shaped locking foot anchor rod at different angles.

[0004] However, when using the existing anchor rod, the anchor rod is inserted into the pre-drilled hole in the wall, and then the mortar is injected into the wall hole by the anchor rod. If the hole is facing downward and the mortar is not set, the anchor rod may fall off under the action of gravity and needs to be reinstalled.

[0005] In order to solve the above problems, an anchor rod installation structure is proposed in the present application. Utility Model Content

[0006] The utility model provides an anchor rod installation structure to solve the technical problem in the prior art that if the hole faces downward and the mortar is not set, the anchor rod may fall off under the action of gravity and needs to be reinstalled.

[0007] The utility model provides a technical solution for solving the above technical problems as follows: an anchor rod installation structure, comprising a mounting shell, a telescopic rod is installed on the top of the mounting shell, a supporting mechanism is installed on the top of the telescopic rod, the supporting mechanism comprises a balancing plate installed on the top of the telescopic rod, a pad is fixed on the top of the balancing plate, a first hydraulic rod is installed on the top of the pad, a U-shaped plate is installed on the top of the first hydraulic rod, and two flaring plates are installed on the top of the U-shaped plate.

[0008] A spring is welded between the balancing plate and the mounting shell. The spring is provided to play a supporting role, so that if the opening of the hole drilled on the wall faces downward, the spring can play a supporting role.

[0009] A slide groove is provided inside the installation shell, and the slide plate can be moved inside the installation shell by arranging the slide groove.

[0010] The inner sliding clamp of the slide groove is connected with a slide plate, and the support mechanism installed on the top can be moved when the slide plate is moved.

[0011] A second hydraulic rod is installed on the outer side of the slide plate. By shortening the second hydraulic rod, the balance board is moved closer to the wall. When the balance board moves closer to the wall, the anchor rod placed on the top can be moved.

[0012] A fixing plate is installed at the other end of the second hydraulic rod, and the fixing plate can be connected to the wall through bolts.

[0013] The beneficial effects of the utility model are:

[0014] By shortening the second hydraulic rod, the balance plate is moved closer to the wall. When the balance plate is moved closer to the wall, the anchor rod placed on the top can be moved so that the anchor rod can enter the hole drilled in the wall. After most of the anchor rod has entered the hole drilled in the wall, the two first hydraulic rods close to the wall are shortened so that the two first hydraulic rods close to the wall no longer block the outer wall of the anchor rod, and the anchor rod is continued to be pushed into the hole. At this time, the tail of the anchor rod is close to the top of the U-shaped plate close to the wall. At this time, the anchor rod will be completely inserted into the hole drilled in the wall, so that the anchor rod can enter the hole drilled in the wall.

When the balance plate 31 is close to the wall At this time, the anchor rod placed on the top can be moved so that the anchor rod can enter the hole drilled in the wall. After most of the anchor rod enters the hole drilled in the wall, the two first hydraulic rods 33 close to the wall are shortened so that the two first hydraulic rods 33 close to the wall no longer block the outer wall of the anchor rod. At this time, the anchor rod is continued to be pushed into the hole. At this time, the tail of the anchor rod is close to the top of the U-shaped plate 34 of the wall. At this time, the anchor rod will be completely inserted into the hole drilled in the wall, so that the anchor rod can be in the hole drilled in the wall.
