As shown in the figure, the shield tunnel track support device includes: a first support frame 1 and a second support frame 2. Among them, the first support frame 1 is used to be horizontally arranged in the shield tunnel, and both ends of the first support frame 1 are in contact with the tunnel segment 3, and the top surface of the first support frame 1 is used to set the transport track 4. Specifically, in the shield tunnel, the first support frame 1 is arranged horizontally, and each end of the first support frame 1 is in contact with the tunnel segment 3 at the corresponding position. The side of the first support frame 1 facing the top of the shield tunnel is the top surface, and the transport track 4 is arranged on the top surface of the first support frame 1. The transport track 4 can be a battery car track or other tracks, and this embodiment does not impose any restrictions on this.

[0023] During specific implementation, the transport track 4 may be a single row, a double row, or multiple rows, and may also be provided with switches, which is not limited in this embodiment.

[0024] The first end of the second support frame 2 ( Figure 1 The upper end shown in the figure) is vertically arranged at the center of the bottom surface of the first support frame 1. The first support frame 1 and the second support frame 2 are fixedly connected, so the first support frame 1 and the second support frame 2 form a "T"-shaped structure, which can stably support the transport track 4. The second end ( Figure 1 The lower end shown) is in contact with the tunnel segment 3 at the bottom of the shield tunnel.

[0025] In specific implementation, the length of the second support frame 2 is determined according to the required height of the transport track 4, and the length of the first support frame 1 is determined according to the required height of the transport track 4 and the distance between the tunnel segments 3 on opposite sides of the shield tunnel.

[0026] It can be seen that in the present embodiment, the first support frame 1 is horizontally arranged in the shield tunnel and both ends thereof are in contact with the tunnel segments 3, the second support frame 2 is arranged on the first support frame 1 and in contact with the tunnel segments 3 at the bottom of the shield tunnel, and the transport track 4 is arranged on the first support frame 1. In this way, the first support frame 1 and the second support frame 2 can stably support the transport track 4, and can realize the improvement of the height of the transport track 4 in the shield tunnel, so that the transport track 4 can be widened from one row to two rows, and switches can be set according to actual needs, which effectively improves the transportation efficiency, thereby improving the excavation efficiency of the shield tunnel, saving construction period, and solving the problem of low efficiency caused by only one row of battery vehicles for transportation during shield tunnel excavation in the prior art.

This inclined state matches the inclined state of the end face of the corresponding end of the first support frame 1. The inclined state of the contact surface of the tunnel segment 3 at the corresponding end of the first support frame 1 matches the inclined state of the end face of the corresponding end of the first support frame 1. In this way, the pad 5 at the corresponding end of the first support frame 1 is also inclined, so that the pad 5 can be in close contact with the tunnel segment 3.

[0029] In specific implementation, each pad 5 can be cut from a 5 mm thick steel plate.
