Embodiment Construction

[0005] A kind of most economical overpass bridge, it is by one-way lane (1), turning lane (2), straight lane bridge (3), non-motor vehicle crossing bridge (4), turning lane (5), line-merging area (6) ), the one-way turning lane (7) is formed, the vehicle that enters the intersection from each direction through the two-way lane passes through 4 one-way turning lanes (7) separated by 500-1000 meters (or depending on the actual situation), and passes through the turning lane (5 Or 2) merge into the normal two-way lane after entering the merging area (6) or entering the one-way turning lane (7), so as to realize the purpose of going their own way at the intersection of two-way lanes without interfering with each other.

Abstract

The invention provides a most-inexpensive overpass bridge which consists of four common straight bridges (3), eight common turning paths (2, 5) and four one-way roads (1) and (7) and is characterized in that a two-way crossroad is changed into four one-way crossroads, so that when vehicles running on the two-way crossroad approach the crossroad, the crossroad is respectively separated into four respective one-way roads which respectively have certain distances (being favorable for steering and forming one lane) from one another, so that the two-way crossroad is changed into four one-way crossroads; and after passing through the four straight bridges and eight common ground steering paths, the vehicles enter respectively required directions so as to enter respective two-way lanes, thus finishing the intersection process of the two-way lanes.

Description

Technical field [0001] It belongs to the field of road and bridge design, especially involving a most economical overpass Background technique [0002] The present flyover design is either a three-layer large ring type, or a double-layer large-angle turning design, and its common point is that the curves are all characterized by large-scale long bridge overhead bridges. The construction cost is high, and the floor area is large, so it is not suitable for application in cities. Contents of the invention [0003] In order to solve the above-mentioned problems, the present invention provides an overpass bridge design scheme with extremely low construction cost and very little land occupation, which can be applied to urban centers. The intersection is separated at a certain distance and turned into 4 one-way lanes, so that each lane maintains a certain distance between 500-1000 meters, so that two two-way lane intersections become 4 one-way lane intersections, A total of 4 o...
