Drainage device of floating tunnel
The invention relates to the technical field of subsea tunnels, and particularly discloses a drainage device of a floating tunnel. The drainage device comprises a water accumulation system, water transportation systems and a drainage system, the water accumulation system is arranged in the tunnel, the drainage system is arranged on a pontoon, the water transportation systems are respectively arranged in the tunnel and the pontoon, a steel cable is arranged between the tunnel and the pontoon, and pipelines of the water transportation systems are fixed to the steel cable. Water is gathered into the water accumulation cavity of the tunnel from the tunnel through two slope angles, water located underwater is led out of the tunnel into the pontoon through a water pump and a pressurization mode, the pressure of water and air is larger than the external atmospheric pressure by changing the size of the pontoon, the water can be discharged out of the pontoon, a purification structure is arranged, water is prevented from polluting sponge or a river surface, whether water in the pontoon needs to be discharged or not is judged through a water level detection structure, and the problem that the pontoon sinks to cause tunnel sinking due to gravity increase of the pontoon caused by excessive water is avoided.
本发明涉及海底隧道技术领域，具体公开了一种悬浮隧道的排水装置，包括积水系统、水运输系统和排水系统，积水系统设于隧道内，排水系统设于浮舟上，水运输系统分别安置于隧道和浮舟内，隧道与浮舟之间设置有钢索，水运输系统的管道固定于钢索上。本发明通过两个斜坡角度使得水从隧道上汇聚至隧道的积水腔内，又通过水泵和加压的方式使得位于水下的水从隧道内引出至浮舟内，在通过改变浮舟的体积，使得水加空气的压力大于外接大气压，使得水能够从浮舟内排出，并且设置有净化结构，避免水污染海绵或河面，通过水位检测结构来判断浮舟内的水是否应该排出，避免了水过多导致浮舟的重力增加从而导致浮舟下沉使得隧道下沉的问题。
