Water stop structure and method for underwater suspension tunnel pipe joint connector
An underwater suspension tunnel pipe joint water stop structure comprises a first pipe joint, a second pipe joint and a multi-layer water stop structure for connecting the first pipe joint and the second pipe joint in a sealed mode. The multi-layer water stop structure comprises a first water stop belt with an anti-corrosion function, a second water stop belt arranged on the inner side of the first water stop belt, a third water stop belt in a pre-compression shape and a shear key for limiting shearing and tensile deformation of the third water stop belt, and the third water stop belt is fixedly connected with the first pipe joint and the second pipe joint. Excessive stretching and shearing of the water stop belt are avoided, permanent loss of the water stop belt is prevented, breakage of the water stop belt is avoided, the failure risk of the water stop belt during opening and shearing dislocation of the floating tunnel pipe joints is effectively reduced, the sealing water stop function between the pipe joints under the limiting working condition is guaranteed, the sealing water stop service life of the water stop structure is prolonged, and the reliability of the water stop structure is improved. And the use requirements of the floating tunnel pipe joint connector are met. The invention further provides a water stopping method for the underwater floating tunnel pipe joint connector.
水下悬浮隧道管节接头止水结构，包括管节一和管节二、密封连接管节一和管节二的多层止水结构，多层止水结构包括具有防腐蚀功能的第一止水带、设置在第一止水带内侧的第二止水带、呈预压缩状的第三止水带和对第三止水带的剪切、拉伸变形进行限位的剪力键，第三止水带分别与管节一和管节二固接。本发明避免止水带的过度拉伸、剪切，防止止水带的永久性损失，避免止水带断裂，有效降低悬浮隧道管节发生张开、剪切错动时止水带的失效风险，保证极限工况下管节间的密封止水功能，延长止水结构的密封止水寿命和可靠性，满足悬浮隧道管节接头使用需求。本发明还提供一种水下悬浮隧道管节接头止水方法。
