Referring to fig. 2 to 6, the AB-direction straight tunnel 10 includes a first underground tunnel 11 a straight in the B direction and a second underground tunnel 12B straight in the a direction, the CD-direction straight tunnel 20 includes a third underground tunnel 21C straight in the D direction and a fourth underground tunnel 22D straight in the C direction, and the pair of left-turn tunnels includes a fifth underground tunnel 31 a left-turning in the C direction and a sixth underground tunnel 32B turning left in the D direction, one end of the fifth underground tunnel 31 communicates with the first underground tunnel 11, the other end of the fifth underground tunnel 31 communicates with the fourth underground tunnel 22, one end of the sixth underground tunnel 32 communicates with the second underground tunnel 12, and the other end of the sixth underground tunnel 32 communicates with the third underground tunnel 21.
The first underground tunnel 11 and the second underground tunnel 12 are arc-shaped and symmetrically arranged. The first underground tunnel 11 and the second underground tunnel 12 are arranged to be arc-shaped tunnels, so that underground inner space can be effectively utilized, the first underground tunnel 11 and the second underground tunnel 12 can be prevented from passing through the lower parts of main body engineering of the third underground tunnel 21 and the fourth underground tunnel 22, development difficulty of the underground tunnels is reduced, and the situation that the ground collapses is avoided. Wherein the maximum distance between the first underground tunnel 11 and the second underground tunnel 22 is not less than 300m for better stabilization.
Referring to fig. 2, in the present embodiment, the two ends of the AB-direction straight tunnel 10 are respectively provided with a first open section 51 and a second open section 52, and the two ends of the CD-direction straight tunnel 20 are respectively provided with a third open section 53 and a fourth open section 54, wherein one end of the first underground tunnel 11 and one end of the second underground tunnel 12 are converged at the first open section 51, and the other end of the first underground tunnel 11 and the other end of the second underground tunnel 12 are converged at the second open section 52; one end of the third underground tunnel 21 and one end of the fourth underground tunnel 22 are converged at the third open section 53, and the other end of the third underground tunnel 21 and the other end of the fourth underground tunnel 22 are converged at the fourth open section 54.
The main engineering of the third underground tunnel 21 and the main engineering of the fourth underground tunnel 22 are symmetrically arranged side by side, that is, the whole third underground tunnel 21 and the whole fourth underground tunnel 22 are symmetrically arranged side by side.
If the underground development space is limited, the main structure of the first underground tunnel 11 and the main structure of the second underground tunnel 12 may be passed through the third underground tunnel 21 and the fourth underground tunnel 22 from below, but in order to reduce the difficulty of developing the underground tunnels as much as possible, the main structure of the first underground tunnel 11 may be disposed below the third open section 53, that is, the main structure of the first underground tunnel 11 may be passed through the third open section 53 from below, and the main structure of the second underground tunnel 12 may be disposed below the fourth open section 54, that is, the main structure of the second underground tunnel 12 may be passed through the fourth open section 54 from below, by utilizing the feature that the first underground tunnel 11 and the second underground tunnel 12 are provided in an arc shape and symmetrically. Because the third open section 53 and the fourth open section 54 are the closest parts of the third underground tunnel 21 and the fourth underground tunnel 22 to the ground, if the first underground tunnel 11 and the second underground tunnel 12 pass through from the lower part, the problem of overlarge development difficulty caused by overlarge ground thickness can be avoided, the development cost and the development time are effectively reduced, meanwhile, the underground space structure can be kept stable, and the situation of ground collapse is avoided.
If the actual underground space that develops is enough, then can make the main part engineering of first underground tunnel 11 and second underground tunnel 12 directly bypass third underground tunnel 21 and fourth underground tunnel 22, not only can further reduce the development degree of difficulty of underground tunnel, also can make the structure of underground space further improve stability and fastness simultaneously, avoid the condition that the ground appears collapsing.
