Pre-stressed anchor cable pipe and floating tunnel pipe
The invention discloses a pre-stressed anchor cable suspension tunnel pipe joint connector structure which is characterized in that a pipe joint connector is connected with a pre-stressed anchor cable through a group of pressure-bearing rings arranged in the annular direction, the pressure-bearing rings mounted on a pipe joint connector foundation are different in size and are arranged on the pipe joint connector foundation in a staggered manner, and proper gaps are reserved; the structural form of the pressure-bearing ring is changed, the bearing capacity, especially the torsion resistance, of the pressure-bearing ring is enhanced, and the requirements for stress and displacement deformation between floating tunnel pipe joints under complex environmental loads and working loads can be met. The complexity and diversity of the deep water and wide water crossing problem can be well dealt with, the anti-torsion capacity of the structure can be enhanced while the anti-pressure capacity of the structure is effectively enhanced, and the suspension tunnel is well protected. The pre-stressed anchor cable is additionally arranged, the bending resistance and torsion resistance of the structure can be greatly improved, meanwhile, the structural style is simple, the overall safety performance of the structure can be effectively improved, and structural damage is avoided.
本发明公开一种预应力锚索悬浮隧道管节接头结构，该管节接头通过在环向上设置的一组承压环与预应力锚索连接在一起，安装在管节接头基础上的承压环大小不一，交错布置在管节接头基础上并留有适当间隙，其改变了承压环的结构形式，增强了承压环的承载能力尤其是抗扭能力，能够满足复杂环境荷载与工作荷载下悬浮隧道管节间的受力和位移变形要求。能较好应对深水、宽水跨越问题的复杂性和多样性，在有效增强结构抗压能力的同时，也能增强结构的抗扭转能力，对悬浮隧道起到了很好的保护作用。增设了预应力锚索，不仅能够大大提高结构的抗弯能力与抗扭转能力，同时结构型式简单，能有效提高结构整体的安全性能，避免结构破坏。
