摘要
Provided is a crossroads structure to facilitate re-modelling of an established crossroads, wherein two low tunnels (3, 4) with a height of no lower than 2 metres and no higher than 3 metres are provided at two ends of a first artery (1) near the centre of an interchange; the road surface of the first artery (1) on the surface is divided by the low tunnels into left and right surface lanes (5, 6) able to be used by large vehicles and the travelling directions of which run counter to each other; and the road surface above the low tunnels forms a platform for turning around (7) able to be used by large vehicles and stretching across between the two surface lanes. The structure is extremely convenient for re-modelling an established crossroads without needing to make any change to a second artery and without needing to construct a flyover on the first artery. Using two low tunnels (3, 4) and two platforms for turning around (7) enables split-flow for large and small vehicles and for vehicles travelling in each direction, making changing crossroads smoother. Further provided is a half-sunk/half-elevated tunnel structure, making construction easier and reducing use of resources.
