Problems solved by technology

However, the multi-level overpass solution, although the land occupation has been reduced, has greatly increased the bridge construction cost, especially the noise problem caused by driving and the traffic around the overpass is more inconvenient, which makes the commercial value of the buildings around the overpass depreciate greatly, thus losing Is it necessary to build such an overpass without losing its status as a commercial center?

Embodiment Construction

[0018] Combine below figure 1 To specifically illustrate the realization of the driving mode.

[0019] exist figure 1 Among them, the north-south road is the ground floor, and the east-west road is connected by a flyover. The four driving routes starting from the south end are marked as arrow 1, arrow 2, arrow 3, and arrow 4. The four driving routes starting from the north end are marked as arrows 5. Arrow 6, arrow 7, and arrow 8 add up to four directions, and the driving methods in each direction are:

[0020] Arrow 1 is a straight line from south to north, and this line is always heading north;

[0021] Arrow 2 is the left-turn route traveling from south to east, and arrow 3 is the driving route that needs to make a U-turn. When the arrows 2 and 3 drive forward from the first fishhook-type double-line turnaround overpass (A), pass the second fishhook-type turnaround overpass (A) on the traffic area (E) . After the arrow 2 gets off the bridge, turn right and enter the tu...

Abstract

The invention relates to an omnidirectional overpass method for changing lanes at road crossings. It is to build a U-turn ramp in the overhead areas at both ends of the bottom of a general overpass bridge, so that one overpass bridge can undertake the two functions of going straight and turning around. . In addition, a fishhook-shaped overpass will be built on both sides of the overpass, and each fishhook-shaped overpass will be responsible for solving the problem of turning left in two driving directions and turning around in the direction of a main road. When the driver reaches the overpass, he only needs to choose whether to go straight or turn, and the last bridge can complete the lane change in any direction. This overpass bridge can carry out full underground construction completely, and three overpass ramp bridges all solve the omnidirectional overpass problem that needs at least five overpass ramp bridges to solve. It is the simplest and most convenient omnidirectional overpass bridge known at present. It occupies less land, does not demolish roadside buildings, and can carry out construction without affecting traffic, which is very suitable for construction in the city center.

Description

technical field [0001] The present invention relates to a simplified and improved omnidirectional overpass for changing lanes at road crossings. I use three overpass ramp bridges to completely solve the omnidirectional overpass method that currently needs at least five overpass ramp bridges to solve. The simplest and most convenient omnidirectional overpass in the patent. It occupies less land, does not need to demolish roadside buildings, and can carry out construction without affecting traffic, which is very suitable for construction in the city center. Background technique [0002] The existing or under construction omni-directional overpasses in the world now either need to cover an area of ​​nearly 100,000 square meters, or need to build three or even four floors above the road. Multi-layer overpasses with up to a dozen trails. The urban center area is the area with the most serious traffic jams, and it is most in need of building omnidirectional overpasses. Building ...
