[0032] Please refer to the attached Figure 1-Figure 4, shows an inclined shaft TBM tunnel foundation device provided by an embodiment of the present application, including: a sleeper leg 1, a sleeper 2, a track 6 and a semi-enclosed guard 8, wherein the bottom end of the sleeper leg 1 is fixed to the ground of the tunnel 10, the sleeper 2 is fixedly installed on the top of the sleeper leg 1, each sleeper 2 corresponds to at least two sleeper legs 1, the sleeper 2 is supported overhead by the sleeper legs 1, the track 6 is fixedly installed on the sleeper 2, the track 6 extends along the length direction of the tunnel 10, the TBM equipment travels on the track 6, the bottom end of the semi-enclosed guard 8 is fixed to the ground of the tunnel 10, and the sleeper leg 1 is located on the inner side of the semi-enclosed guard 8.

[0033] This solution is applied in an inclined shaft tunnel. Since the tunnel is in an inclined state, the track 6 is also in an inclined state. When the TBM equipment walks or runs on the track 6, the force applied to the track 6 is not perpendicular to the track 6. Compared with a horizontal tunnel, the TBM equipment generates an inclined force on the track 6, which easily causes the sleeper leg 1 to deform, thereby causing the track 6 to deform. The designed semi-enclosed guard 8 is used to stabilize the sleeper leg 1, making it difficult to tilt and able to withstand greater force, thereby achieving a stable foundation and preventing the track from deforming, providing a safe and stable foundation for the equipment to travel, improving safety performance, and avoiding the occurrence of dangerous accidents.

[0034] The auxiliary facilities in tunnel 10 are pedestrian climbing, which are arranged along one side of the tunnel and do not affect the basic safety.

[0035] In one embodiment, the bottom end of the sleeper leg 1 is fixedly connected to the rock foundation at the bottom of the tunnel 10 via the first anchor locking member 4, thereby ensuring the stability of the bottom end connection of the sleeper leg 1.

[0036] In one embodiment, both ends of the sleeper 2 are fixedly connected to the rock foundation on the side of the tunnel 10 through the second anchor locking piece 5, so as to further improve the stability of the sleeper 2. The sleeper 2 and the sleeper leg 1 can be fixed by welding to ensure the stability of the structure of the sleeper 2 and the sleeper leg 1.

[0037] In one embodiment, a reserved bolt hole is opened on the sleeper 2, the rail 6 and the sleeper 2 are pressed and fixed by the rail clamp 7, and the rail clamp 7 and the sleeper 2 are fixedly connected by bolts to facilitate the fixed installation of the rail 6 and the sleeper 2.

[0038] In one embodiment, a plurality of sleepers 2 are arranged along the length direction of the tunnel 10 , and a connecting rib 3 is fixedly connected between two adjacent sleepers 2 to increase the stability between the plurality of sleepers 2 .

[0039] In one embodiment, the semi-enclosed guard 8 is vertically arranged, the sleeper leg 1 is perpendicular to the ground of the tunnel 10, and a wedge block 9 is arranged on the inner side of the semi-enclosed guard 8 to contact the inner side of the semi-enclosed guard 8 and the side of the sleeper leg 1 at the same time.

[0040] like Figure 4 In the middle setting, the side of the sleeper leg 1 close to the semi-enclosed guard 8 is inclined, the inner side of the semi-enclosed guard 8 is vertical, and the wedge block 9 is arranged with a structure of being larger at the bottom and smaller at the top. When the sleeper leg 1 is tilted and squeezed, the wedge block 9 will not slide out.

[0041] In one embodiment, the semi-enclosed guard 8 is a reinforced concrete structure. Generally, the semi-enclosed guard 8 is constructed first in the tunnel, and then the sleeper leg 1 is installed.
