Floating tunnel joint water stop and vibration reduction structure and method
The invention relates to a floating tunnel joint water-stopping and vibration-reducing structure which is connected between adjacent pipe sections of a floating tunnel, comprises a plurality of layers of water-stopping structures which are connected with the adjacent pipe sections in a sealing manner, and is characterized by further comprising friction dampers which are hinged between the adjacent pipe sections and are adjustable in friction force, and the friction dampers are arranged on the inner sides of the plurality of layers of water-stopping structures; and sliding friction motion is formed along with relative motion of adjacent pipe joints. The frequent impact of the long-term dynamic working condition of the floating tunnel on the multi-layer water stop structure is relieved, the fatigue working condition of the multi-layer water stop structure is improved, the fatigue life of the multi-layer water stop structure is prolonged, the durability of the multi-layer water stop structure is improved, the failure risk of the multi-layer water stop structure is reduced, and the service life of the multi-layer water stop structure is prolonged. And the friction damper is arranged on the inner side of the multi-layer water stop structure, so that overhaul and maintenance are facilitated, and the practicability is high. The invention further provides a floating tunnel joint water stop and vibration reduction method.
悬浮隧道接头止水减振结构，连接在悬浮隧道相邻的管节之间，包括密封连接相邻管节的多层止水结构，其特征在于：还包括铰接在相邻管节之间且摩擦力可调的摩擦阻尼器，摩擦阻尼器设置在多层止水结构的内侧，随相邻管节的相对运动而形成滑动摩擦运动。本发明缓解悬浮隧道长期动态工况对多层止水结构造成的频繁冲击，改善多层止水结构的疲劳工况，延长多层止水结构的疲劳寿命，提高多层止水结构的耐久性能，降低多层止水结构的失效风险，提高悬浮隧道接头处密封止水的稳定性和可靠性，摩擦阻尼器设置在多层止水结构的内侧，方便进行检修维护，实用性高。本发明还提供一种悬浮隧道接头止水减振方法。
