Abstract

The invention discloses an overpass which is formed by overlapping three cross-shaped bridge surfaces, ramps of the three cross-shaped bridge surfaces, and one layer of ground surface. The overpass comprises four through-traffic lanes, four right turning lanes, four left turning lanes, four U-turning lanes, and four pedestrian passageways, and is composed of a first-layer ground surface, a second-layer bridge surface, a third-layer bridge surface, a fourth-layer bridge surface, and ramps of the surfaces, wherein each of the first-layer ground surface and the second-layer bridge surface is provided with two through-traffic lanes, two U-turning lanes and two pedestrian passageways, and each of third-layer bridge surface and the fourth-layer bridge surface is provided with two right turning lanes and two left turning lanes. According to the overpass, a method of turning lane pairing and grouping is used, so that the eight turning lanes are divided into four pairs and two groups, and the eight turning lanes can be reasonable set. By using the overpass disclosed by the invention, a crossroad with branch lines, or branch lanes of a multi-line staggered junction can be communicated with the lanes of the overpass in all directions. By adopting the overpass disclosed by the invention, a separation type overpass or an overpass with a two-layer structure can be transformed to the overpass with the structure having the three bridge surfaces and the four layers. Most of the bridge surfaces of all layers and the respective ramps are positioned on a roadbed, so that when the overpass disclosed by the invention is built, houses are not required to be removed, and the removal compensate is saved.

Description

Technical field [0001] The present invention relates to an overpass. More specifically, the present invention relates to an overpass with a four-layer structure with three decks, which is different from the existing overpass. Background technique [0002] The "Judge Harry Preggson" overpass in Los Angeles is the most complex overpass in the world. The Griffith Overpass in Birmingham, UK is also very complicated and is nicknamed "Spaghetti Crossing". There are also many complex overpasses similar to "spaghetti crossing" in our country. For example: Xinzhuang overpass in Shanghai, Huqingping overpass, Xizhimen overpass in Beijing, and Wulidian overpass in Chongqing. There are two reasons why these complex overpasses are complicated: 1. The curve of the left-turning lane is too long, the turn around is too large, and the curve becomes a winding road. 2. There are branch lines, which increase the complexity of the overpass. [0003] These complex overpasses can be simplified. For ...
