Description

A kind of full straight overpass bridge
Technical field
The utility model relates to a kind of overpass bridge, especially relates to a kind of full straight overpass bridge that is used for the crossroad.
Background technology
Traffic congestion is the disadvantage of urban development, and incommutation peak time, it is outstanding that the problem of blocking up more shows, and the crowded blockage problem of urban highway traffic has become the restriction economic development, reduces people's living standard, weakened one of bottleneck of economic vitality.
Urban traffic blocking is often caused by the intersection, and is particularly outstanding at the parting of the ways.Mostly existing city cross road is usual friendship traffic lights form, and the great crossing of the part traffic volume is provided with overpass bridge, and clearly, grade separation can effectively be alleviated crossroad access and block up.The existing conventional overpass bridge has been realized the full intercommunication such as no red green grade of crossroad, can alleviate the crossroad access problem of blocking up, and improves the urban traffic present situation.But its shortcoming is also apparent in view:
1, floor space is bigger: existing overpass bridge floor space great majority are all more than hundreds of mu, and are limited for crossroad, city reconstruction overpass bridge feasibility;
