(Reference) Figure 1The entire reinforcement mechanism is set on the cracked rock mass and positioned by bolts 25.

[0021] Spring plate 4 is in the shape of a corrugated plate. Guide slider 3 and spring plate 4 are set in a groove opened on one side wall of Z-shaped plate 2. Guide slider 3 is fixed on main block 1.

[0022] The one-way valve 9 includes a sealing cylinder 21, a sealing ball 22, a spring 23, and a partition 24. The sealing ball 22 and the spring 23 are disposed between the sealing cylinder 21 and the partition 24, and the sealing cylinder 21 and the partition 24 are fixed on the main block 1. One end of the spring 23 contacts the sealing ball 22, and the other end of the spring 23 contacts the partition 24. The partition 24 is in the shape of a circular plate and has several evenly distributed through holes on its body.

[0023] The handle 15 is shaped like a cylinder with one side integrally connected to a prism. A central shaft 16 is movably sleeved in the middle of the cylinder of the handle 15. The cylinder of the handle 15 is set in a circular plate groove opened on the main block 1, and the end of the central shaft 16 is fixed on the main block 1.

[0024] The air column 10 is movably sleeved in the straight tube cavity 6. The air column 10 is cylindrical and has several evenly distributed toothed grooves on one side wall.

The intercepting block 17 is fixed on the central shaft 16, and one end of the intercepting block 17 contacts the corrugated spring plate 18.

[0026] Working principle: After the reinforcement mechanism is fixed to the rock mass, the spring plate 4 rebounds and pushes the Z-shaped plate 2, so that the two Z-shaped plates 2 move closer to each other, applying elastic pressure to the rock mass and preventing the increase of rock mass cracks. When installing the reinforcement mechanism, the worker manually turns the handle 15. The rotation of the handle 15 drives the reciprocating motion of the air column 10. Because when the airflow passes through the one-way valve 9, it can only push up the sealing ball 22 and then quickly pass through the gap between the sealing cylinder 21 and the sealing ball 22. In this way, the reciprocating motion of the air column 10 provides power for the airflow in the straight tube cavity 6, the straight tube cavity 7 and the L-shaped tube cavity 8. Specifically, when the air column 10 is inserted into the main block 1, it pushes the gas in the straight tube cavity 6 into the straight tube cavity 7. The process of moving away draws gas from the L-shaped cavity 8 into the straight cavity 6, and this cycle repeats. The airflow is gradually injected into the straight cavity 7. The air pressure propels the guide rod 11, which moves and drives the control block 12. The control block 12 moves and lifts the pressure block 5, which in turn drives the Z-shaped plate 2 to move. In this way, the two Z-shaped plates 2 gradually move away from each other until a suitable distance is maintained between them. The Z-shaped plates 2 can then be fixed to the rock mass by bolts 25. During this process, the rubber disc 20 on the handle 15 seals the thin cavity 19 to prevent gas leakage. In this way, the main block 1 and the Z-shaped plate 2 are fixed synchronously. After the reinforcement mechanism is fixed, a hard object can be used to support the handle 15 to ensure that the rubber disc 20 does not block the thin cavity 19.
