[0059] first part: figure 1 pattern drawing

[0060] figure 1 The pattern drawn is a one-story driveway. There are six lanes No. 1, 2, 5, 6, 7, and 8. No. 1 is a straight lane from south to north, No. 2 is a straight lane from north to south, No. 5 is a right-turning lane from south to east, and No. 6 is a straight lane from south to east. North to west right turn lane, No. 7 is east to north right turn lane. No. 8 turns right from west to south.

[0061] the second part: figure 2 pattern drawing

[0062] figure 2 The pattern is the direction of each lane on the second-story bridge deck and the third-story bridge deck. The bridge deck on the second floor is set with 4 straight lanes from west to east, 10 left-turn lanes from north to east, 13 U-turn lanes for southbound traffic, 14 U-turn lanes for northbound traffic, 15 U-turn lanes for eastbound traffic, and U-turn lanes for westbound traffic. 16. The last part of lane 9 turning left from south to west, the last pa...

Abstract

The invention relates to an overpass which is a ramp-free three-layer overpass with two bridge floors at a crossroad. The overpass has three layers. The first layer is provided with two north-south straight lanes and four right turning lanes. And the second layer is provided with a west-to-east straight lane, a north-to-east left-turning lane, a south-coming vehicle U-turn lane, a north-coming vehicle U-turn lane, an east-coming vehicle U-turn lane, a west-coming vehicle U-turn lane, a last part of a south-to-west left-turning lane, a last part of an east-to-south left-turning lane and a last part of a west-to-north left-turning lane. And the third layer is provided with an east-west straight lane, a front half part of an east-south left-turning lane, a front half part of a west-north left-turning lane and a front half part of a south-west left-turning lane. The overpass is provided with sixteen lanes including four right turning lanes, four straight lanes, four left turning lanes and four turning lanes.

Description

technical field [0001] The present invention relates to a kind of overpass bridge, more specifically, the present invention relates to a kind of three-storey overpass bridge with two bridge decks and no ramps at the intersection which is different from existing overpass bridges. Background technique [0002] Most of the overpasses at crossroads in my country are ramp overpasses. Due to the existence of ramps, the safety of overpasses is marked with a big question mark. For example, the Balitai Overpass in Tianjin has several accidents of falling from the bridge. The ramp in the ramp overpass means that it is necessary to turn and go uphill or downhill. Turning and going uphill or downhill should be done at the same time, which means that bridge accidents are prone to occur. However, ramps have the benefit of solving both turns and weaving between lanes on each level. There are four left-turning lanes in the overpass, and the weaving problem is easily solved. Very conveni...
