The invention relates to the field of underwater tunnels, and provides an underwater tunnel ventilation shaft with overhauling and escaping functions and an underwater tunnel ventilation system. The underwater tunnel ventilation shaft with the overhauling and escaping functions comprises a shaft body and a support structure; the shaft body is of a flexible bendable structure, and the bottom of theshaft body communicates with an air duct of an underwater tunnel; the support structure is fixed underwater and connected with the shaft body so that the top of the shaft body can stretch out of thewater; and the shaft body is internally provided with an overhauling and escape ladder. The underwater tunnel ventilation shaft has the overhauling and escaping functions. The influence of the arrangement mode of the shaft body on the marine environment is small, the project cost, the operating cost, the implementation difficulty, the construction risk and the operating risk are reduced, and the situation that the water ecological environment is damaged by building an artificial island is avoided.
本发明涉及水下隧道领域,提供了一种具有检修、逃生功能的水下隧道通风竖井及系统,所述具有检修、逃生功能的水下隧道通风竖井包括竖井本体和支护结构,所述竖井本体为柔性可弯曲结构,所述竖井本体的底部与水下隧道的风道连通,所述支护结构固定在水底、并与所述竖井本体连接,以使所述竖井本体的顶部伸出水面;所述竖井本体内设有检修逃生梯。该具有检修、逃生功能的水下隧道通风竖井。这种竖井本体的设置方式对海洋环境影响较小,降低了工程造价、运行成本、实施难度、施工风险及运行风险,避免了建设人工岛所造成水生态环境破坏。
