Embodiment approach

[0009] People walk on the sidewalk on the ground; vehicles go straight to the left and right, and follow the standard bridges and roads; vehicles turn back, and turn back on the ground under the bridge between the right bridges; avoid the sidewalk. This scheme is applicable to the left-hand system, as long as the entrance and exit are reversed.

[0010] Implementation Effect:

[0011] Compared with the alfalfa bridge, the hyperbolic bridge has one less level, no right-turning circle, less land occupation, direct left-hand traffic, no detours, unimpeded intercommunication, and excellent efficiency and safety. Compared with the multi-layered bridge, the traffic efficiency They are the same, two floors less, lower construction costs, no demolition, built in the core area of ​​the city, hyperbolic bridges can be turned back, but multi-storey bridges do not have this function, the turning function is a powerful auxiliary technology for smooth traffic, the Clover Bridge, Although i...

Abstract

The invention relates to a technology for unblocking intersection traffic, in particular to a satellite-type hyperbolic full-reverse unblocked overpass which is formed by combining two reverse straight left bridges which are respectively arranged at two longitudinal ends. Each reverse straight left bridge is formed by combining a straight left bridge, a longitudinal left bridge and a transverse left bridge. A hyperbolic direction changing technology is applied to achieve reverse passing of straight left passing and direct left passing and decrease overpass layers, a bridge (ground) surface hyperbolic section and a ground (bridge) surface hyperbolic section are applied to omit an intersection, straight left lanes of same-directional roads and the same at-grade intersection between the straight left lanes of an X-shaped overpass in a road section are omitted, the intersection between longitudinal and transverse left lanes is omitted, and unblocked straight passing and left passing of theintersection are achieved. Only two layers are needed, a main road intersection in a core area can be built without dismantling, straight, left, right and return unobstructed passing and pedestrian passing ground sidewalks can be achieved, and the intersection passing demand is met.

Description

Technical field: [0001] The invention belongs to the field of highway construction, in particular to a "satellite" hyperbolic full retrograde unimpeded overpass. Background technique: [0002] Urban traffic is congested, and "clover type" interchange bridges and multi-layered interchange bridges are commonly used now. The Clover Bridge has three floors in total, and the left direction is an interchange path, which has an impact on safety and efficiency. The multi-layered overpass bridge has four floors in total, and it goes directly to the left, and the traffic effect is very good. However, due to geographical restrictions, most of the urban core areas cannot be set up. Now it is proposed to invent a new overpass technology with good effect and suitable for construction in the core area. Invention content: [0003] A new technology for smooth traffic at urban crossroads: "satellite" hyperbolic full retrograde traffic bridge. (referred to as hyperbolic bridge) figure 1 ...
