Underwater bridge docking system

Abstract

The invention discloses an underwater bridge docking system which comprises internal corner joints and external corner joints. Each internal corner joint and the corresponding external corner joint are arranged on the pipe heads at the two ends of each submarine pipeline. Each submarine pipeline is arranged on underwater bearing tables. The external corner joint of the current submarine pipeline achieves the functions of guide and locating in the submergence process. In the submergence process of the next submarine pipeline, the corresponding external corner joint is in contact with the internal corner joint of the current submarine pipeline in the submergence process, the function of a sliding groove is achieved, so that guide and locating are achieved in the submergence process of the current submarine pipeline and the next submarine pipeline, and the submarine pipelines are submerged in place according to preset accuracy. According to the scheme, the problems that in the prior art,a large submergence ship is utilized for conveying and pipe section underwater submergence, an underwater jack and water pressure of the two sides of a tunnel cavity are utilized for completing docking, a waterstop band is utilized for water stop, and the construction period of a sinking pipe submergence docking process is long can be solved; and the effect of shortening the construction period isachieved.

Description

technical field [0001] The invention belongs to the technical field of underwater transportation, and in particular relates to an underwater bridge docking system, in particular to a construction process for a novel underwater bridge docking joint. Background technique [0002] With the development of global economy and technology, transportation across rivers and straits has gradually increased. In order to meet the needs of production and life, reduce the impact on the surrounding environment, and solve problems such as shipping in large areas of water, underwater tunnel technology has emerged as the times require. The main construction techniques of underwater tunnels are immersed tube method, mine method and shield method. [0003] The total length of the immersed tube method tunnel is significantly shorter than that of the mine method and the shield tunnel method. The section shape of the pipe joint can be selected flexibly. During the construction, each process can be...
