Embodiment Construction

[0013] like figure 1 As shown, the buoyancy adjustment box 2 is rigidly fixed below the floating tunnel body 1 through the connecting device 4 . The anchoring system consists of a cable 3 and an underwater foundation, and the floating tunnel body 1 and the buoyancy adjustment box 2 are fixed in the water area through the cable 3 .

[0014] like figure 2 As shown, the cables 3 are symmetrically arranged on both sides of the suspension tunnel body 1 and the buoyancy adjustment box 2 . The different water levels are shown in the figure, namely the high water level a and the low water level a'. When the water level changes to the low water level a', part of the floating tunnel body 1 is exposed to the water surface and loses part of its buoyancy. At this time, the water level in the buoyancy adjustment tank 2 can be adjusted to provide additional support for the floating tunnel body 1 to offset the floating tunnel. The lost buoyancy of tube body 1.

Abstract

The invention discloses a submerged suspension tunnel with adjustable buoyancy, comprising a tunnel tube body, an anchoring system and a buoyancy adjusting system. The tunnel tube body is steadily suspended in water through the anchoring system; the buoyancy adjusting system is composed of a gas compressor, a gas tube and a buoyancy adjusting box. The buoyancy adjusting box is rigidly connected with the tunnel body and is provided with a water gate, and the buoyancy of the tunnel tube body can be adjusted by controlling the water intake amount of the buoyancy adjusting box through the gas compressor. The buoyancy adjusting box of the submerged suspension tunnel with adjustable buoyancy can provide extra support to the tunnel tube body when the tunnel tube body loses part of the buoyancy, thus getting rid of the influence of the water level change to the safety of the floating tunnel.

Description

technical field [0001] The invention relates to an underwater floating tunnel capable of adjusting its own buoyancy. Background technique [0002] The underwater floating tunnel, also known as the Archimedes bridge, is a new traffic solution across waters. It is submerged below the water surface and uses buoyancy to support the weight of the tunnel and the traffic load. For areas where the span of the water area is too large or there are environmental protection requirements, the floating tunnel in the water is the preferred way to connect across the water area. From the perspective of dynamic stability, the buoyancy of the floating tunnel in water is greater than the sum of gravity and traffic load, and the remaining buoyancy (ie buoyancy minus gravity and traffic load) is borne by the cables connected to the tunnel and the underwater foundation. The basic structure of the floating tunnel is as follows: the tunnel is connected by segmented pipe bodies, and the pipe body ge...
