[0002] Geotechnical engineering is a new technical system established in civil engineering practice in the 1960s. Geotechnical engineering takes solving rock and soil engineering problems, including foundation and foundation, slope and underground engineering problems, as its research object. The excavation of tunnels and other structures also belongs to the part of geotechnical engineering.

[0020] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0021] Please refer to Figures 1-3 In the embodiment 1 of the present application, a rock-soil engineering support protection frame for easy adjustment of support comprises a support frame structure 3 and a shed roof structure 9. The shed roof structure 9 is symmetrically provided with the support frame structure 3 on both sides. The support frame structure 3 comprises a support frame 14 connected to the shed roof structure 9. The support frame 14 is provided with a side wall plate 4 on both sides of the end away from the shed roof structure 9. The side wall plate 4 is provided with a plurality of wall nails 5 on the outer side. The wall nails 5 are embedded in the side wall of the tunnel. The side wall plate 4 is rotatably provided with a support rod 6. The support rod 6 and the support frame 14 are connected by a positioning rod 11.

[0022] The device uses two symmetrical support frame structures 3. The support frame structure 3 uses the side wall plate 4 installed on the wall of the tunnel as a fulcrum. The support frame 14 adhering to the top surface of the tunnel and the support rod 6 pointing to the ground of the tunnel are installed on the side wall plate 4. The angle between the support frame 14 and the support rod 6 is adjustable. After adjusting the angle, the positioning rod 11 is used to support between the two, so as to form a fixed structure.

[0023] The device can change its shape by changing the angle between the support frame 14 and the support rod 6 and adjusting the height position of the side wall plate 4, so that the support structure 3 can be attached to the wall surface of tunnels of different sizes, and the wall surface nails 5 on the side wall plate 4 are connected with the tunnel wall surface, and the support rod 6 supports the ground, so that a stable triangular support structure is formed, which can provide strong support for the tunnel and ensure the safety inside the tunnel. The shed roof structure 9 is connected between the two support structures 3 to form a shed roof for preventing the top from falling or falling.

[0024] The device has a stable and convenient to adjust support structure 3, and has a structural strength that is significantly higher than that of similar adjustable structures, because the adjusting method used by the device does not need to use various telescopic rods, so that the structure of the material itself is used as support after being stabilized, and the stress is uniformly dispersed and not concentrated on the telescopic adjusting position of the rod, so that the device has higher structural strength, can effectively improve the carrying capacity and safety.

[0025] As another embodiment of the utility model, please refer to Figures 1-3 The main difference between embodiment 2 and embodiment 1 is that:
