TYPICAL UNDERWATER TUNNEL BRIDGE

摘要

Typical underwater tunnel-bridge belongs to the underwater structures and is designed to reduce the time and material costs in the construction of traffic routes and pipelines under water obstacles. It comprises concreted sections interconnected by a waterproof lining, with cavities filled with concrete between the concrete sections. New same therein is that the concrete sections are situated on an underwater bridge support containing bridge girder bridge, which are installed and fixed concrete sections, between which security gateways, on the coast of continental thereto cut out of the tunnel. The technical result is to simplify and reduce the cost of construction of the underwater tunnel.
