Sectional island type self-balancing Archimedean bridge

Abstract

The invention relates to a sectional island type self-balancing Archimedean bridge which belongs to a new form of submerged floating tunnels in water and comprises a right bridge, an approach bridge and a monitoring management system, wherein the right bridge comprises a sectional island, a connecting bridge segment, a standard bridge segment, tyre type seal rings, a restriction ring, a vibration insulating device and other devices (such as a safe escape device and the like), and the sectional island type self-balancing Archimedean bridge is characterized in that the restriction in up, down, left and right directions can be supplied for the bridge segment by the sectional island through the restriction ring. Through the structure, the submerged weight ratio of the bridge segment can be controlled to be within 0.9 to 1.1 and still keep stable, thereby overcoming the deficiency of one-way restriction by using anchor line and upright post supports. The restriction ring is sleeved outside the end part of the bridge segment and can move along the axial direction to realize the connection with or separation from the sectional island or other bridge segments. When necessary, the bridge segment can be disengaged from the restriction and floated on the water surface so as to be convenient for rescue or maintenance and replacment. The tyre type seal rings are fixed in seal grooves at both ends of the bridge segment, and high pressure gas or liquid can be filled into the tyre type seal ring to realize the seal between the bridge segment and the restriction ring, transfer restriction force and insulate dynamic responses.

Description

technical field [0001] The invention relates to a tunnel suspended in water, namely the Archimedes bridge. Background technique [0002] Since the Archimedes Bridge was put forward in the 1880s, it has been accepted as a new traffic concept. Many countries in the world have invested heavily in research and have achieved a lot of scientific research results. Fantasy is gradually becoming reality. However, because the traffic concept of the Archimedes bridge involves a wide range of fields and there are many problems to be solved, a practical Archimedes bridge has not been built so far in the world. [0003] The archimedes bridge structure that has been proposed for vehicle traffic problems is as follows: the top surface of the archimedes bridge is located 20-40 meters below the water surface; It is composed of the connection part with the two sides and the anchoring system; the pipe body is constrained and positioned by the cables anchored on the anchor piles of the bottom ...

AI Technical Summary

Problems solved by technology

The body weight of this kind of structural tube is greater than the buoyancy, and the buoyancy-to-weight ratio is generally less than 0.8. Also, under unfavorable working conditions, the load is large and the construction cost is high.

There are also completely free, buoy-anchored and float-over types, which are not suitable for solving large-flow transportation problems (such as railway transportation) due to poor stability.
