The invention relates to the field of submerged tunnels and provides a submerged tunnel ventilation shaft and a submerged tunnel ventilation system. The submerged tunnel ventilation shaft comprises afloating platform, a shaft body and a plurality of first anchor cables. The shaft body is of a flexible bendable structure. The bottom of the shaft body communicates with an air duct of a submerged tunnel. The top of the shaft body extends out of the water surface and is connected with the floating platform. One ends of the first anchor cables are connected with the water bottom, the other ends ofthe first anchor cables are connected with the floating platform, and the multiple first anchor cables are distributed on the floating platform in the circumferential direction. The shaft body arrangement mode has less impact on the marine environment, the construction cost, operational cost, implementing difficulty, construction risks and operational risks are lowered, and the situation that artificial island construction damages the water ecological environment is avoided.
本发明涉及水下隧道领域,提供了一种水下隧道通风竖井和水下隧道通风系统,所述水下隧道通风竖井包括漂浮平台、竖井本体和多条第一锚缆,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,所述竖井本体的顶部伸出水面、并与所述漂浮平台连接;所述第一锚缆的一端与水底连接,另一端与所述漂浮平台连接,多个所述第一锚缆在所述漂浮平台的周向上均有分布。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。
