Abstract

The invention discloses a bridge self-adjusting protection device under severe sea conditions and a control method. The bridge self-adjusting protection device comprises a main body structure arrangedaround a bridge pier structure and a water injection and drainage adjusting structure arranged inside a bridge pier. The main body structure is mainly composed of metal outer frames and rubber bags.The number of the metal outer frames is two, the metal outer frames wrap the wave facing face and the wave backing face of the bridge pier respectively, at least three rubber bags are arranged in themetal outer frames side by side, one side of each rubber bag is tightly attached to the bridge pier, and the other side of each rubber bag is tightly attached to the inner side of the corresponding metal outer frame. The water injection and drainage adjusting structure injects water into or drains water from the rubber bags to adjust the size of the bridge pier. The bridge self-adjusting protection device is high in applicability, simple in structure, durable, diverse in application and capable of effectively protecting bridge safety under severe sea conditions.

Description

technical field [0001] The invention belongs to the technical field of marine engineering bridges, and in particular relates to a self-adjusting protection device and control method for pier under severe sea conditions. Background technique [0002] The sea-crossing bridge is a large-scale marine transportation project in my country and a transportation guarantee for the development of the marine economy. In recent years, with the continuous development of the ocean and the rapid development of my country's transportation industry, more and more cross-sea bridges have been built, and the plan is to continue to develop in outer sea areas and deep sea areas. At present, many cross-sea bridges have been built, such as the Hangzhou Bay Bridge, the Hong Kong-Zhuhai-Macao Bridge, etc. The water depth of these bridges is mostly about 10m to 40m, while the water depth of the Bohai Bay Channel, Qiongzhou Strait Channel and Taiwan Strait Channel currently planned Most of them are abo...
