Problems solved by technology

However, most of the existing vertical lifting open bridges are vertical lifting open girder bridges. In order to realize the opening, it is necessary to build additional tall bridge towers, which not only greatly increases the construction cost, but also destroys the entire bridge construction to a certain extent. aesthetics

Abstract

The invention discloses a vertical lifting open arch bridge, which comprises a main arch and a main girder. The main arch is divided into two arch foot sections and a middle arch section. The fixed beam section is spliced ​​from front to back. The vertical lifting system is installed on the middle arch section. The opening hole beam section is hoisted under the vertical lifting system. The counterweight trolley that translates the bridge forward and backward. At the same time, the invention also discloses a method for opening and closing an arch bridge, which includes two steps of moving the counterweight trolley to the mid-span and lifting the beam section of the opening hole when opening, and including lifting the beam section of the opening hole downward and the counterweight trolley when closing Translate two steps toward the beam end. The invention is reasonable in design, convenient in implementation, safe and stable in the process of opening and closing, and has good use effect. The vertical lifting system for opening is installed on the main arch and the beam section of the opening hole, and the opening and closing of the bridge is realized by relying on the main arch to provide support. .

Description

technical field [0001] The invention belongs to the technical field of bridge construction, and in particular relates to a vertical lifting open arch bridge and an opening and closing method thereof. Background technique [0002] At present, an open bridge is a bridge in which the upper structure of the bridge can move or rotate so that ships can pass smoothly in order to take into account the needs of waterway and land transportation. When the land transportation is not very busy, and there are ships sailing on the river and the fixed bridge cannot be built above the navigation clearance, it is necessary to build an open bridge to solve the water and land transportation problem. When the ship needs to pass, the land traffic is interrupted, and the open bridge is opened; after the ship passes, the open bridge is closed, and the land traffic resumes. [0003] At present, the opening methods of the opening bridge include horizontal rotation, vertical rotation, vertical lift a...
