Abstract

The invention relates to a single-floor non-jam overpass in the shape of butterfly, which is characterized in that: one overpass in the height of one floor is at the direction of AA; each side in the direction of BB has an overpass in the height of half floor; the part of A overpass at half-floor height is connected to the top circular arc of B overpass. The invention realizes the non-jam of automobile, pedestrian, and bicycles in the crossroad. Said inventive overpass solves the problem of full functional overpass, since the narrow roads in the city. It occupies less ground with beautiful appearance and substantial reduction of cost.

Description

[technical field] [0001] The invention belongs to the technical field of road and bridge construction. [technical background] [0002] At present, there are traffic congestion problems in cities all over the country. With the continuous increase of vehicles, the congestion problem is becoming more and more serious. Status quo: Overlapping multi-layer overpasses are used at crowded intersections. Due to large investment, large land use, and high space occupation, they are only suitable for construction in the suburbs of cities or places far away from cities, and are not suitable for installation in urban core areas at all. At present, intersections in urban core areas are places where traffic congestion is the most concentrated, and signals are used to control straight and left traffic. 1 / 4 time driving, 3 / 4 time staying. The crossing efficiency of right-hand traffic and pedestrians and bicycles is extremely low. is the main cause of congestion. The new bridge type was in...
