[0002] A tunnel is a cavern with a cross-sectional area greater than 2 square meters that is built for a certain purpose and in any way underground. It is an engineering building buried in the ground and a form of human use of underground space. Tunnels can be divided into traffic tunnels, hydraulic tunnels, municipal tunnels, mining tunnels, and military tunnels. Traffic tunnels are the most widely used type of tunnels.

[0003] At present, in order to have better passability, it is generally adopted to excavate multiple parallel tunnels to increase the tunnel's passability. Two adjacent parallel tunnels are generally separated from each other, and the passage of the two parallel tunnels is independent of each other and does not affect each other. However, two parallel tunnels that do not affect each other have limitations in use. For example, in an emergency, if an accident occurs in one of the tunnels, it is impossible to use the other tunnel for rapid evacuation.

[0004] Therefore, the prior art needs to be improved. Utility Model Content

[0025] Example 1

[0026] This embodiment provides a double-hole tunnel that is interconnected, such as Figure 1 As shown, the specific structure is described as follows.

[0027] Please refer to Figure 1 As shown, the interconnected double-hole tunnel of this embodiment is mainly composed of a tunnel body 1, and two parallel tunnels A 2 and B 3 are opened inside the tunnel body 1. A wall 4 is arranged between tunnel A 2 and tunnel B 3. The wall 4 separates tunnel A 2 and tunnel B 3. The wall 4 supports the tunnel body 1 and ensures the safety of the tunnel body 1.

[0028] Further, combined with Figure 1 As shown, two groups of A tracks 7 are laid inside the A tunnel 2, and two groups of B tracks 8 are laid inside the B tunnel 3. Crossovers are installed on the right sides of the two groups of A tracks 7 and the two groups of B tracks 8, so that locomotives can enter from one track and cross over the other track, making the use of the A track 7 and the B track 8 more flexible.

[0029] In some implementations of this embodiment, the number of A vertical grooves 5 continuously arranged is 2 to 5, and the number of B vertical grooves 6 continuously arranged is 2 to 5. Figure 1 As shown, preferably, there are 2 A vertical grooves 5 and 2 B vertical grooves 6. The 2 A vertical grooves 5 are opened continuously, and the A vertical grooves 5 are located on the side of the wall 4 close to the A tunnel 2, and the B vertical groove 6 on the left is deeper than the B vertical groove 6 on the right. Similarly, the 2 B vertical grooves 6 are also opened continuously, and the B vertical grooves 6 are located on the side of the wall 4 close to the B tunnel 3, and the B vertical groove 6 on the right is deeper than the B vertical groove 6 on the left. The wall 4 with the A vertical grooves 5 and the B vertical grooves 6 is stepped. The lengths of the 2 A vertical grooves 5 and the 2 B vertical grooves 6 are both 40 meters.

[0030] Furthermore, the A vertical groove 5 and the B vertical groove 6 are symmetrical to each other, the left side of the A vertical groove 5 and the right side of the B vertical groove 6 are vertically aligned, and the left side of the A vertical groove 5 and the B vertical groove 6 are connected to each other, and the width of the connection is 4 meters or 5 meters, so locomotives and vehicles can pass through.

[0031] Combination Figure 1 As shown, the A track 7 is connected to a branch rail 9, and the end of the branch rail 9 away from the A track 7 is connected to the B track 8. The branch rail 9 passes through the joint between the A vertical groove 5 and the B vertical groove 6, so that the locomotive vehicle can enter the B tunnel 3 from the A tunnel 2, or enter the A tunnel 2 from the B tunnel 3.

[0032] Example 2

[0033] The interconnected double-hole tunnel of this embodiment is basically the same as the interconnected double-hole tunnel of Example 1, and the main difference is that a reinforced structure is added. Due to the opening of A vertical groove 5 and B vertical groove 6, the strength of the wall 4 at this location is reduced. The A vertical groove 5 and B vertical groove 6 adopt a double-layer primary support and secondary lining support form, wherein the first layer outer primary support adopts an arch frame, the second layer inner primary support adopts a steel arch frame, and the secondary lining adopts reinforced concrete to form a reinforced concrete wall 4. Anchor rods are inserted into the reinforced concrete wall 4, and the two ends of the anchor rods are fixedly connected to the grid steel frames on both sides. The grid steel frames clamp the surface of the reinforced concrete wall 4 to further strengthen the fixation.

[0034] The working principle of the interconnected double-hole tunnel of the utility model is as follows:

[0035] The interconnected double-hole tunnel of the utility model includes a tunnel body 1, and the tunnel body 1 has an A tunnel 2 and a B tunnel 3, and the A tunnel 2 and the B tunnel 3 are separated by a wall 4. The continuous A vertical grooves 5 form a step shape, and the continuous B vertical grooves 6 also form a step shape. The deepest B vertical groove 6 is connected to the deepest A vertical groove 5. The closer the A vertical groove 5 or the B vertical groove 6 is to the connection point, the deeper it is. The stepped A vertical groove 5 and the B vertical groove 6 are conducive to maintaining the stability of the wall 4. The sub-track 9 passes through the connection point, and the two ends of the sub-track 9 are connected to the A track 7 and the B track 8 respectively. The vehicles on the A track 7 in the A tunnel 2 can enter the B track 8 in the B tunnel 3 through the sub-track 9, which increases the flexibility of use of the two parallel tunnels. It is very convenient to use and is convenient for vehicles to change lanes.
