The design is suitable for road reconstruction of all multi-lane roads from four bidirectional lanes, the whole vehicle traffic capacity of the reconstructed road is 5-7 times of that of the original traffic light control road, the reconstructed road can provide more than 700 underground parking spaces per kilometer, the flood storage capacity of more than 20 ten thousand cubic meters per kilometer, and the specific design content is as follows:
1. the two crossing main roads on the urban ground are both roads with the total width of a bidirectional four-lane road not more than 32 meters and special roads on which ground bridges are not allowed to be built.
1) The ground is designed to be the crossroad to control traffic by traffic lights, and other ground road sections are designed to pass freely; the crossroad is about 100 meters towards four directions (the distance is determined according to specific conditions), and ground one-way ramp connecting channels are built on motor lanes adjacent to non-motor lanes on two sides of the road to connect the ground and the underground layer.
2) The underground first floor is designed to climb to the underground first floor through the underground second floor expressway straight lane of the secondary main road and cross the underground second floor expressway straight lane of the main road at the position of the crossroad; the underground one-way ramp connecting channel is built underground on the ground non-motor vehicle lane and is connected with the underground one-way ramp connecting channel and the underground two-layer; the two ground one-way ramp connecting channels and the two underground one-way ramp connecting channels are respectively connected with the inlet and the outlet of the semicircular double-loop turning area on the underground layer, and the semicircular double-loop turning area is an anticlockwise annular lane; between the semicircular double-loop-turn-around area and the corresponding semicircular double-loop-turn-around area of the next crossroad of the same trunk road, a one-way straight-going connecting road of the next layer is built at the underground position of the ground non-motor vehicle road to connect the two semicircular double-loop-turn-around areas between the two crossroads; an underground parking lot A is built in the open space between the two unidirectional straight connecting roads, and a road middle section passing underground pedestrian passageway is built between the underground parking lot A and the semicircular double-ring-road turning-around section; an underground parking lot B is built in the vacant space between the semicircular double-loop turning area and the crossroad, and four communicated underground pedestrian passages are built in four directions beside the crossroad.

5) Because the total width of the primary and secondary main road ground roads is not more than 32 meters, the turning area of the semicircular double-loop road on the underground layer has a limit to the turning radius of the vehicle entering the vehicle, and the specific limit value is determined according to the width of the road. The vehicles running on the express way of the underground second floor can run straight and turn right on the underground second floor, the vehicles needing to turn left can drive into the underground first floor through the underground one-way ramp connecting road, after the vehicles meeting the limit value of the semicircular double-loop U-turn area turn around through the U-turn area, the vehicles can drive into the underground second floor through the underground one-way ramp connecting road and turn right to realize the left turn, and also can drive into the ground through the ground one-way ramp connecting road after turning around and then turn right to realize the left turn; the overlong vehicle which does not meet the limit value of the semicircular double-loop U-turn area must directly run on the ground to realize left turn through a red and green light at a ground crossroad.
2. The total width of a main road in two crossed main roads on the ground of the existing urban road is more than 32 meters, and the total width of a secondary main road is not more than that of the main road.
1) The ground of the two crossed main roads is designed into a ground express way, a ground express way straight lane and a right-turn lane are on the ground, and a secondary main road ground straight lane at the crossroad climbs to the ground layer to cross with the main road ground straight lane. The crossroad is about 100 meters towards four directions (the distance is determined according to specific conditions), and ground one-way ramp connecting channels are built on motor lanes adjacent to non-motor lanes on two sides of the road to connect the ground and the underground layer.
2) The underground first floor is designed to climb to the underground first floor through the underground second floor expressway straight lane of the secondary main road and cross the underground second floor expressway straight lane of the main road at the position of the crossroad; the underground one-way ramp connecting channel is built underground on the ground non-motor vehicle lane and is connected with the underground one-way ramp connecting channel and the underground two-layer; the two ground one-way ramp connecting channels and the two underground one-way ramp connecting channels are respectively connected with the inlet and the outlet of the semicircular double-loop turning area on the underground layer, and the semicircular double-loop turning area is an anticlockwise annular lane; between the semicircular double-loop-turn-around area and the corresponding semicircular double-loop-turn-around area of the next crossroad of the same trunk road, a one-way straight-going connecting road of the next layer is built at the underground position of the ground non-motor vehicle road to connect the two semicircular double-loop-turn-around areas between the two crossroads; an underground parking lot A is built in the open space between the two unidirectional straight connecting roads, and a road middle section passing underground pedestrian passageway is built between the underground parking lot A and the semicircular double-ring-road turning-around section; an underground parking lot B is built in the vacant space between the semicircular double-loop turning area and the crossroad, and four communicated underground pedestrian passages are built in four directions beside the crossroad.
3) The main and secondary main roads are designed as urban expressways on the underground second floor, and the straight lanes and the right-turn lanes are on the underground second floor.
4) The ground vehicle goes straight through the ground one-way ramp connecting road to enter the underground first floor, goes straight through the one-way straight connecting road of the underground first floor, and then goes straight through the underground one-way ramp connecting road of the front crossroad to enter the underground second floor express way for running; and on the contrary, the underground two-layer vehicle enters the ground and runs in the same direction.
