Air curtain waterproof device and method for subsea tunnel
The invention discloses an air curtain waterproof device and method for a subsea tunnel, and relates to the technical field of tunnel waterproofing. The air curtain waterproof device comprises a steel reinforcement framework grid cover, an inflation pipeline, a collision sensor, an air box and a central controller, the steel reinforcement framework grid cover is arranged on the outer side of the subsea tunnel, the collision sensor is fixed to the steel reinforcement framework grid cover, and the central controller with an alarm is arranged on the inner wall of the tunnel. A plurality of air boxes are arranged in the tunnel waterproof layer, pressure gauges are arranged in the air boxes and communicated with the inflation pipeline through connecting pipes, control valves are arranged on the connecting pipes, the inflation pipeline is externally connected with a high-pressure air source, and the collision sensors, the pressure gauges and the control valves are connected with the central controller. The invention further provides an air curtain water-proof method for the subsea tunnel, the air curtain water-proof device is used for forming an air curtain, seawater is prevented from entering the tunnel through cracks, the water-proof protection effect is achieved, and safe operation of the subsea tunnel is effectively guaranteed.
本发明公开了一种用于海底隧道的空气帷幕隔水装置及方法，涉及隧道防水技术领域。本发明的空气帷幕隔水装置包括钢筋骨架网格罩、充气管道、碰撞感应器、空气箱和中央控制器，钢筋骨架网格罩设置在海底隧道外侧，碰撞感应器固定在钢筋骨架网格罩上，隧道内壁设有带报警器的中央控制器，隧道防水层内设有多个空气箱，空气箱内设有压强计并通过连接管与充气管道连通，连接管上设置有控制阀门，充气管道外接高压气源，碰撞感应器、压强计和控制阀门分别与中央控制器相连接。本发明还提出了一种用于海底隧道的空气帷幕隔水方法，利用空气帷幕隔水装置形成空气帷幕，隔绝海水经裂缝进入隧道内，起到了隔水防护的作用，有效保障了海底隧道的安全运行。
