Description

TECHNICAL FIELD

[0002] Bridge refers to the building for crossing natural or artificial obstacles, which is generally composed of five large components and five small components. The five large components refer to the bridge span upper structure and the lower structure that bear the transportation load of cars or other vehicles, which are the guarantee of the safety of the bridge structure, mainly including bridge span structure (or bridge hole structure, upper structure), bridge support system, pier and abutment, pile cap and excavation well or pile foundation. The five small components refer to the components directly related to the service function of the bridge, which are called bridge deck structure in the past, including bridge deck pavement, waterproof and drainage system, railing, expansion joint and light illumination. In some large bridges, the auxiliary structures also include bridge head fort, approach bridge and other structure settings. The above structures are generally referred to as bridge structural components, and the bridge is completed by installing these structural components.

[0003] In order to ensure the service life of the bridge, most of the bridge structural components need to be sprayed with one or more layers of rust-resistant, wear-resistant or waterproof coating on the surface after production.
