Embodiment Construction

[0013] figure 1 Among them, one, in the vertical direction of the longitudinal road 1 on the original ground, a horizontal underpass tunnel 11 is set, and the underpass tunnel 11 is set at the height of allowing motor vehicles to pass through, about 5 meters. The two ends of the underpass tunnel start at the ground level and connect with the horizontal road in the vertical direction of the original intersection. Second, the right lane of the original longitudinal road is set as a vertical left and right turning ramp 2 that gradually goes downward, before the intersection of the vertical and horizontal sidewalks on the ground , crossing the ground sidewalk obliquely downward to the right, and after meeting with the horizontal underpass tunnel, it is divided into two roads: one road merges into the underpass tunnel and goes up, and completes the right-turning function of the lane; the other way goes along the right side of the underpass tunnel and is parallel to the ground level....

Abstract

The invention relates to an underground intercommunicated overpass which relates to the technical field of overpasses. A transverse downwards penetrated tunnel 11 is arranged in the vertical direction of an original ground longitudinal road 1, a longitudinal original road right lane is set as a gradually downward longitudinal left-turning and right-turning ramp 2, and the longitudinal left-turning and right-turning ramp and the transverse downwards penetrated tunnel are converged and then divided into two paths: one path is converged into the downwards penetrated tunnel and upwards advances; and the other path advances along the right side of the downwards penetrated tunnel and parallel to a ground plane, enters an underground left-turning ramp entrance 6, transversely downwards penetrates through a transverse road to an exit at the opposite side, then turns and advances along the other side thereof and converges with the transverse tunnel at a low position. A transverse downwards penetrated tunnel right lane 10 obliquely downwards penetrates through a sidewalk and is then divided into twp paths: one path is a transverse right-turning ramp 5 upwards advancing along the right side of a longitudinal road and intersecting with the ground, and the other path is an underground left-turning ramp, which advances at the outer side of the right-turning ramp 5 and parallel to the ground, enters the underground left-turning ramp entrance 6, transversely penetrates through the longitudinal road to an exit at the other side from the underground, turns and upwards advances along the other side and converges with the longitudinal road at the position below the ground.

Description

technical field [0001] The invention relates to the technical field of overpasses. Background technique [0002] At present, known all-intercommunication overpasses all bridge over the ground, such as the inline full-interchange single-layer overpass that Chinese Patent No. is 200510022194.6. But for some tourist cities or world heritage protection cities and regions, it is not allowed to destroy the landscape by building bridges on the ground, such as Hangzhou, the existing all-interchange overpass just cannot solve its traffic congestion problem. Contents of the invention [0003] In order to overcome the above disadvantages, the present invention provides an underground full-interchange overpass, which can achieve the purpose of not destroying the landscape and alleviating traffic congestion. [0004] The technical solution of the present invention to solve its technical problems is: an underground full-interchange overpass composed of the original ground road, the und...
