Deformable bridge suitable for different water levels

Abstract

The invention discloses a deformable bridge suitable for different water levels. The deformable bridge comprises main bodies arranged in bilateral symmetry, the ends, close to each other, of the mainbodies on the left and right sides are in contact connection with each other, the ends, away from the contact center, in the main bodies on the left and right sides are provided with rotating axes penetrating front and back, rotating shafts are fixedly connected in the rotating axes on the left and right sides, and arched bridge cavities with openings away from the rotating axes are formed in ends, away from rotating axes, in the main bodies on left side and right side correspondingly. By means of the mode that deformation is conducted firstly and then locking is conducted, the main bodies arerotated upwards, so that the space for ships to pass through is obtained, and the situation that the ships cannot pass through due to the fact that the ships are too high or the water line rises is prevented; and then the arched bridge is driven to ascend while the main bodies rotate, and finally the arched bridge is fixed through threaded sleeve rods, so that the defect that only ships can passthrough but vehicles cannot pass through due to bridge deformation is overcome, and the problem that ground traffic is hindered due to ship passing is prevented.

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...

Problems solved by technology

[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
