Description

Background technique

Highway and bridge engineering refers to the planning, design, construction, maintenance, and repair of structures that cross waters, valleys, and all traffic passages. In deep valleys with large elevation differences, or across other traffic lines, bridges need to be erected in order to keep traffic flowing, and bustling urban areas sometimes need elevated roads composed of viaducts. The side mountain route is sometimes built with a viaduct instead of a roadbed, either because of the huge excavation of the roadbed, or because of the unstable geological structure, or because of the protection of the landscape.

In the usual sense, the construction platform is a steel frame structure system built by scaffolding to assist in the construction of the construction project. However, in the construction process of the bridge, in addition to the steel frame structure system, it is also necessary to erect drainage pipes on the outside of the viaduct The construction of power lines and other power lines requires the use of special movable construction platforms for auxiliary construction, which is convenient for the staff to erect and construct.
