Joint structure of floating tunnel pipe joint
The invention relates to a floating tunnel pipe joint connector structure, and belongs to the technical field of floating tunnel connection. The device is arranged under the horizontal plane, is fixed on an anchoring structure on one side far away from the horizontal plane through an anchor cable, and comprises a first pipe joint and a second pipe joint which are connected, and a joint structure arranged at the joint of the first pipe joint and the second pipe joint; the joint structure comprises a first water-stop belt, a second water-stop belt, a shear key and a prestressed reinforcement, the first water-stop belt is fixed to the joint of a first pipe joint and a second pipe joint through a hoop and a bolt, the shear key is wrapped with a cushioning material, and the prestressed reinforcement penetrates through the first pipe joint and the second pipe joint. The two ends of the prestressed steel bar extend out of the pipe sections towards the containing cavity, the extending parts are fixed through anchor seats and anchors, and a spring connecting the first pipe section and the second pipe section is further arranged in the middle of the prestressed steel bar. The structure provided by the invention has good water tightness and deformation resistance, and can meet the requirements of vibration and deformation generated by the underwater floating tunnel joint in a complex marine environment.
本发明涉及一种悬浮隧道管节接头结构，属于悬浮隧道连接技术领域。设置在水平面下，通过锚索固定在远离水平面一侧的锚固结构上，包括相连接的第一管节和第二管节，以及设置在二者连接处的接头结构；其中接头结构包括第一止水带、第二止水带、剪力键以及预应力钢筋，第一止水带通过套箍和螺栓固定在第一管节和第二管节的连接处，剪力键上包裹设置有缓震材料，预应力钢筋分别贯通第一管节和第二管节，预应力钢筋的两端朝容纳腔方向伸出管节，伸出部分通过锚座和锚固将其固定，预应力钢筋的中部还设置有连接第一管节和第二管节的弹簧。本发明的结构具有良好的水密性和抵抗变形能力，能够满足复杂海洋环境下水中悬浮隧道接头所产生的振动和变形。
