Embodiment Construction

[0013] As shown in the figure, a large-character crossing full-interchange overpass is composed of the original ground road and a bridge deck elevated in the air. A bow-shaped high-span bridge (5) is erected on the original large-character crossroad (2), with the highest point of the bow The clearance from the ground is the height that allows motor vehicles to pass under the bridge; in addition, a pair of long-handled fishing hook-shaped high-span ramps (6) lie on the outside of the original crosswalk, and the entrance starts from the first lane (14) on the right side of the crossroad, going up to When non-motor vehicles are allowed to pass, turn right and enter the sky above the sidewalk (13) and continue upward until motor vehicles are allowed to pass, cross the vertical road surface parallel to the road surface after crossing the large-shaped vertical road surface, turn left at the bridge head of the horizontal high-span bridge, cross the cross road surface, and turn to down...

Abstract

The invention is an all intercommunicating cross intersection with DA-shaped junction, erecting an arch large-span bridge on the original DA-shaped crossing so that all motor vehicles which come and go and straight run on and under the bridge are unblocked. In addition, a pair of long- handle hook-like large-span ring roads transversely lie outside the original crossing, and a pair of short-handle hook-like large-span ring roads is adjacent to the insides of the long-handle hook-like large-span ring roads, which solves the left-turning difficulty of longitudinal and transverse vehicles; in addition, four arch small-span bridges directly solve the right-turning difficulty. A U-shaped bending ruler is built on the right-falling road of the DA-shaped junction, thus solving the left-turning difficulty of vehicles coming from the left-falling road; besides, a bending ruler ring road is built, adjacent to the left inside of the U-shaped ring road, thus solving the difficulty that vehicles turn left from the right-falling road onto the left-falling road but do no intersect those on the other roads.

Description

technical field [0001] The invention relates to an overpass. In particular, it relates to a full-interchange overpass. Background technique [0002] At present, the known overpass covers a large area and has many layers. For example, Chinese Patent No. 02222131.X semi-submerged four-level overpass, 02222231.6 semi-submerged inner ring type overpass A, B type, not only for four floors, the approach bridge is long, but also To dig tunnels, most of them can only be built in the suburbs. As for the large-shaped multi-limb overpass, basically there is only a turntable overpass, which cannot solve the problem of weaving traffic jams. Contents of the invention [0003] In order to overcome the above-mentioned shortcoming, the present invention provides a kind of brand-new technical scheme: erect a bow-shaped high-span bridge on the original large-shaped intersection crosswalk. The clearance between the highest part of the arched back and the ground is the height that allows th...
