Rapid construction method of camouflage type long-span automatic rapid-extension emergency bridge

Abstract

A rapid construction method of a camouflage type long-span automatic rapid-extension emergency bridge is disclosed. The camouflage type long-span automatic rapid-extension emergency bridge comprises asupporting truss and two sets of rapid-extension bridge systems, wherein the two sets of rapid-extension bridge systems are symmetrically arranged on front and rear banks of a river; the supporting truss is arranged at the middle of the river; the rapid-extension bridge system positioned at the rear side comprises a bridge box; the front side of the bridge box is open and the open part is provided with a box cover; a downhill guide plate assembly is arranged inside the front side of the bridge box; a hydraulic station and two sets of multi-stage telescopic oil cylinders are fixed inside the bridge box; the two sets of multi-stage telescopic oil cylinders are arranged alongside each other in the left-right direction; the length direction of each set of multi-stage telescopic oil cylinder is arranged in the front-rear horizontal direction; and telescopic hydraulic supporting devices are fixed between the lower sides of the ends of same-stage telescopic arms of each set of multi-stage telescopic oil cylinder. In conclusion, the camouflage type long-span automatic rapid-extension emergency bridge is reasonable in structural design. In the event of an emergency, the temporary emergencybridge can be quickly constructed so as to facilitate the passage of people and vehicles.

Description

technical field [0001] The invention belongs to the technical field of bridge equipment, and in particular relates to a rapid construction method of a camouflage-type large-span automatic rapid-stretching emergency bridge. Background technique [0002] Bridges generally refer to structures erected on rivers, lakes and seas to allow vehicles and pedestrians to pass smoothly. When bridges in some places are damaged due to a long period of time or sudden accidents or natural disasters, it is necessary to quickly build emergency bridges to ensure supplies For transportation and personnel travel, some existing emergency bridges are unstable in structure and cumbersome to install. Contents of the invention [0003] In order to solve the deficiencies in the prior art, the present invention provides a rapid construction method of a camouflage-type large-span automatic fast-stretching emergency bridge that can quickly build an emergency bridge in case of an emergency. [0004] In ...
