Easy navigation type over-sea floating bridge

Abstract

The easy navigation type oversea floating bridge includes successively connected floated sections, underwater anchoring blocks, connecting sections and easy navigation pipe. The easy navigation pipe has several passages, each of which has middle part is suspended under the water surface and in the certain depth and two ends on the water surface connected to floating bridge. Train and automobile can pass through the floating bridge and the easy navigation pipe, while ship can navigate in the water over the easy navigation pipe conveniently. Compared with submarine tunnel, the oversea floating bridge has much lower construction cost and short construction period.

Description

technical field [0001] The invention belongs to bridge structure arrangement in the transportation field. Background technique [0002] In the prior art, there are many kinds of pontoon bridges, the most common of which is the "floating body connection type pontoon bridge", which connects the floating bodies with a certain buoyancy one by one, and erects them on the water surface to connect the two banks. Let vehicles and pedestrians pass through the bridge to realize direct communication between the two sides. Practice has proved that this floating bridge has been widely used in practice because of its simple structure, low cost and short construction period. However, this kind of pontoon also has some disadvantages. First of all, because the design of the pontoon bridge is relatively narrow and the stability is poor, it is generally only suitable for use in inland rivers with little wind and waves, and is not suitable for use in inland rivers wit...

AI Technical Summary

Problems solved by technology

[0003] Cross-sea transportation is an old problem. At present, human beings have many ways to realize direct and indirect communication between the two sides of the strait. Some good methods are building submarine tunnels, cross-sea bridges and strait ferries. At present, these methods can satisfy However, the implementation and use of these methods are generally limited by some conditions, such as the high cost of subsea tunnels, the constraints of geological conditions for cross-sea bridges, and the low efficiency of ferries, etc.
