Abstract

The invention discloses an outer sleeve movable type suspension tunnel pipe joint. The outer sleeve movable type suspension tunnel pipe joint comprises a pipe joint body, wherein a movable outer sleeve sleeves the outer wall of the pipe joint body; the movable outer sleeve moves along the length direction of the outer wall of the pipe joint body; and notch parts are arranged at two end parts of the movable outer sleeve. The movable outer sleeve on the outer wall of the tunnel pipe joint has the effects of resisting local leakage and strengthening a weak section; and meanwhile, a function of cleaning floating impurities on the outer surface of the suspension tunnel pipe joint can be realized.

Description

technical field [0001] The invention relates to a pipe joint of a movable floating tunnel with an outer sleeve. Background technique [0002] After decades of development, floating tunnels, as a new cross-sea traffic structure, have been gradually accepted by engineers at home and abroad. The floating tunnel uses the buoyancy of its own closed pipe joints and tension anchor cables to balance the entire system, which makes the structural span independent of environmental conditions. At the same time, compared with traditional immersed tubes and buried tunnels, the relative longitudinal slope of floating tunnels is smaller, which also has the advantage of low project cost per unit length. Therefore, promoting the key technology of floating tunnels is of great significance to the construction of future cross-sea passages. [0003] Generally speaking, the span of the floating tunnel can be as long as tens of kilometers, and it is composed of a series of standardized prefabrica...
