However, the currently used overpass has a complex structure, a long construction period and a high manufacturing cost, in the previous design, the upper and lower bridge structures are one of effective ways for ensuring the smoothness, the design is easy to design for straight going and right turning, but the difficulty of left turning design can not be solved, so that the simple and small-sized cross overpass which has the advantages of simple structure, simple structure and low cost and can be used for motor vehicles and pedestrians without stopping and running on the right and left.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a simple cross overpass to solve the problem of road traffic jam.
In order to achieve the purpose, the utility model provides the following technical scheme:
a simple cross overpass is composed of a downward straight lane, a right-turning lane, a left-turning lane, an upper straight lane and a pedestrian path, wherein the upper straight lane and the pedestrian path are three-dimensionally crossed with the downward straight lane.
Compared with the prior art, the utility model has the following beneficial effects:
the crossroads are crossed and turned at the right angle of 270 degrees to realize left turning, straight lanes can be turned around through two left turning lanes, the crossroads are low in cost and easy to reform and build, the traffic jam state of the existing crossroads and T-shaped road roads is overcome, the traffic safety is improved, motor vehicles and pedestrians can go on the right way without stopping, the traffic efficiency of the roads is improved, and the crossroads are simple in structure and low in cost.

Any obvious modifications or variations can be made to the present invention without departing from the spirit or scope of the present invention.
In one embodiment, as shown in fig. 1-8, a simple crossroad overpass is composed of a downward straight lane 1, a right-turning lane 2, a left-turning lane 3, an upward straight lane 4 perpendicular to the downward straight lane 1, pedestrian lanes 5 and green belts 6, wherein the number of the left-turning lanes 3 is four, and the left-turning lanes are symmetrically distributed on two sides of the upward straight lane, two ends of the left-turning lane 3 are respectively communicated with the upward straight lane and the downward straight lane, and the upward bridge can be turned by 270 degrees to enter the perpendicular straight lane through the left-turning lane 3; after entering another vertical straight lane through the left-turning lane 3, the vehicle can return to the original lane again through the other left-turning lane 3, so that the straight lane can turn around; the number of the right turning lanes 2 is four, and two ends of the right turning lane 2 are respectively communicated with the upper straight lane 4 and the lower straight lane 1.
In one embodiment, as shown in fig. 1, the overpass is a double-layer structure, the downward straight lane 1 is a transverse driving lane and passes through the bottom of the upward straight lane 4, the downward straight lane 1 and the upward straight lane 4 form a cross straight lane, a downward bridge 101 and an upward bridge 401 are respectively arranged at the cross point position of the cross straight lane, the downward bridge 101 is arranged below the ground and is communicated with the downward straight lane 1, the upward bridge 401 is arranged above the ground and is communicated with the upward straight lane 4, and slopes 7 are arranged at both ends of the downward bridge 101 and the upward bridge 401.
In one embodiment, as shown in fig. 1, the pedestrian lane 5 is a non-motor lane, the down-going straight lane 1 and the up-going straight lane 4 are motor straight lanes, and the right-turning lane 2 and the left-turning lane 3 are motor turning lanes.
