Telescopic waterproof device for immersed tube tunnel and tunnel waterproof connecting structure
The invention relates to the technical field of immersed tunnel equipment, and discloses a telescopic waterproof device for an immersed tunnel and a tunnel waterproof connecting structure, the telescopic waterproof device comprises a flexible sleeve and supporting rings, the supporting rings are axially arranged in the flexible sleeve at intervals, the flexible sleeve is used for sleeving a tunnel pipe joint, and positioning holes are formed in the two axial ends of the flexible sleeve; the multiple positioning holes are formed in the circumferential direction of the flexible sleeve at intervals, and embedded positioning screws on the tunnel pipe joint penetrate through the positioning holes for connection. The flexible sleeve is supported by the supporting ring, the stability of the cross section is supported, the flexible sleeve is prevented from falling and being abraded, and the waterproof performance is guaranteed; the flexible sleeve can be directly manufactured and formed in a factory and is directly arranged on a tunnel pipe joint in a sleeving mode during construction, vulcanization construction on site is not needed, and the construction efficiency is improved; the positioning holes have a positioning function, nuts can be assembled on the pre-embedded positioning screws for fixing, the flexible sleeve is anchored on a tunnel pipe joint, and the flexible sleeve deforms to be in close contact with a tunnel in the nut crimping process, so that the waterproof effect is ensured.
本发明涉及沉管隧道设备技术领域，公开了一种用于沉管隧道的伸缩防水装置及隧道防水连接结构，包括柔性套筒和支撑圈，柔性套筒内轴向间隔布置有支撑圈，柔性套筒用于套装在隧道管节上，柔性套筒的轴向两端均设有定位孔，定位孔沿柔性套筒的周向间隔布置有多个，定位孔用于供隧道管节上的预埋定位螺杆穿过连接。支撑圈对柔性套筒进行支撑，支撑横截面的稳定性，避免柔性套筒下坠磨损，保证防水性能；柔性套筒可在工厂内直接制作成型，施工时直接套装在隧道管节上，不需要在现场硫化施工，提高施工效率；定位孔具有定位功能，预埋定位螺杆上可装配螺母固定，柔性套筒锚固在隧道管节上，螺母压接过程中柔性套筒变形与隧道紧密接触，确保防水效果。
