A Variant Bridge Applicable to Different Water Levels

Abstract

A modified bridge suitable for different water levels disclosed by the present invention includes a main body arranged symmetrically on the left and right sides. The rotation axis on the left and right sides is fixedly connected with the rotation axis, and the ends of the main body on the left and right sides away from the rotation axis are respectively provided with arched bridge chambers with openings far away from the rotation axis. In the present invention, by first deforming and then locking, the main body is rotated upwards to obtain a space for ships to pass through, preventing the ships from being impassable due to excessive height of the ship or rising water level, and then driving the arched bridge to rise while the main body rotates Finally, the method of fixing it through threaded sleeve rods solves the disadvantage that the bridge can only pass through ships but not vehicles due to the deformation of the bridge, and prevents the problem of hindering ground traffic due to the passage of ships.

Description

technical field [0001] The invention relates to the technical field of bridge engineering, in particular to a modified bridge suitable for different water levels. Background technique [0002] With the development of railways, the carrying capacity of vehicles has gradually increased, and the load that bridges can bear has also doubled. However, general bridge engineering focuses on the carrying capacity of the bridge itself. The passage of ships only increases the height of the bridge, but in In some special waters, the rise and fall of the water level is more obvious. The rise of the water level will drive the height of the ship to rise, which will cause the ship to fail to pass the bridge normally. The general solution is to realize the folding or translation of the bridge during the bridge design process to give way to the ship. However, it hinders the traffic on the road and is relatively inconvenient. A modified bridge suitable for different water levels described in t...

[0002] With the development of railways, the carrying capacity of vehicles has gradually increased, and the load that bridges can bear has also doubled. However, general bridge engineering focuses on the carrying capacity of the bridge itself. The passage of ships only increases the height of the bridge, but in In some special waters, the rise and fall of the water level is more obvious. The rise of the water level will drive the height of the ship to rise, which will cause the ship to fail to pass the bridge normally. The general solution is to realize the folding or translation of the bridge during the bridge design process to give way to the ship. space for passage, but it hinders the traffic on the road surface, which is relatively inconvenient. A modified bridge suitable for different water levels described in the present invention can solve the above problems
