Hydraulic lifting type overpass

Abstract

The invention relates to a hydraulic lifting type overpass which comprises a bridge deck, a floor surface and multiple oil cylinders, wherein a section of lifting bridge deck is arranged at the road surface; the two ends of the bridge deck are movably connected with the road surface; the floor surface parallel with the road surface is arranged below the bridge deck; a hydraulic lifting system is arranged below the floor surface; the bottom side of the bridge deck is correspondingly connected with the multiple oil cylinders in the hydraulic lifting system; and the bottom side of the floor surface is correspondingly connected with the multiple oil cylinders. The hydraulic lifting overpass provided by the invention can be lifted for use during rush hours and retracted through the oil cylinders when not in use, thereby being favorable for lifting and flexible use according to the traffic conditions and maintaining plane traffic; as the overpass can be lifted for use, the overpass can be set high enough to allow cars lower than 2m to pass, and trucks higher than that height can pass through the plane after the overpass is lowered in a time staggering manner; meanwhile, vehicles exceeding weight limit are not allowed to pass through the bridge deck, therefore the overpass can be built to be light and thin without considering the access of large-tonnage trucks, and the gradient can be greater.

Description

technical field [0001] The invention relates to an overpass, in particular to a hydraulic lift type overpass. Background technique [0002] In order to solve the traffic problem in the city, build a large amount of overpasses usually. Because the overpass is fixed, its construction height and strength must consider the passage of all vehicles, so the bridge is built high, long and heavy, resulting in high construction costs; at the same time, the overpass in the urban area will affect the buildings on both sides of the bridge. Landscape and lighting, the longer and higher the bridge, the greater its impact. Therefore, the bustling city center of many countries does not build bridges, but the resulting traffic jam phenomenon has always had no good solution. Contents of the invention [0003] In view of the above defects, the present invention provides a hydraulic lift overpass that is conducive to the flexible use of lifting according to traffic conditions, does not affec...
