For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0018] See also Figure 1 , Figure 1 The underground road structure according to the utility model is schematically shown.

[0019] A novel underground road structure is characterized in that it includes a U-shaped groove 1 arranged in a soft soil area below a carriageway 6 and pressed on the top of the underground structure, a bottom plate 5 is arranged on the bottom surface of the U-shaped groove 1 for bearing lateral unidirectional force, and supporting piles 2 arranged oppositely are connected on both sides of the bottom surface of the bottom plate 5, and supporting piles 3 arranged oppositely are connected downward on both side surfaces of the U-shaped groove 1.

[0020] Among them, the utility model is suitable for open sections of underground roads in deep soft soil areas.

[0021] Furthermore, the lower end of the bottom plate 5 and the oppositely arranged support piles 2 are reinforced by setting a foundation pit passive zone 4.

[0022] Among them, the passive zone 4 of the foundation pit reinforces the surrounding passive zones to reduce the impact of foundation pit deformation and ground settlement.

[0023] Furthermore, the U-shaped groove 1, the supporting piles 2 and the guard piles 3 are all made of reinforced concrete structures.

[0024] Among them, reinforced concrete structures have the advantages of strong compressive resistance, convenient construction, good durability and large bearing capacity.

[0025] Furthermore, the passive zone 4 of the foundation pit is cement-soil mixing piles.

[0026] Among them, the use of cement-soil mixing piles improves construction efficiency while also greatly improving the bearing capacity or retaining capacity of the pile body.

[0027] Furthermore, the cross-section of the underground road structure is a groove type.

[0028] Furthermore, support piles 2 are arranged on both sides of the U-shaped groove 1, and multiple support piles 2 are arranged along the road direction, with each support pile 2 being spaced between 5 and 6 meters.

[0029] Among them, Figure 1 As shown, the support piles 2 are only arranged on both sides of the U-shaped groove 1. A plurality of support piles 2 are longitudinally arranged along the road direction below the U-shaped groove 1. The spacing between the support piles 2 is 5-6 meters. Through the arrangement of a plurality of support piles 2, the gravity and buoyancy of the entire structure are borne by the support piles.

[0030] The beneficial effects of the utility model are as follows: the utility model adopts the structural form of U-shaped groove 1 and supporting piles 2, uses the supporting piles 2 to bear the gravity and buoyancy of the structure, and uses the bottom plate 5 of the U-shaped groove 1 to bear the lateral unidirectional force, thereby effectively avoiding the need for foundation treatment in the early stage, saving costs, and speeding up the construction progress. The pile foundation of the utility model adopts supporting piles 2 and supporting piles 3, which can significantly reduce settlement after construction and improve water leakage in deformation joints.
