Anti-collision device for cross-sea bridge

Abstract

The invention relates to the technical field of bridge anti-collision, in particular to a cross-sea bridge anti-collision device. Comprising a first air bag and a second air bag which are arranged on a bridge pier in a wrapping mode, the first air bag and the second air bag are filled with buffering media, the buffering media enable the first air bag and the second air bag to be in an expansion state, and the first air bag and the second air bag are each provided with a plurality of water inlet and outlet openings. A plurality of water inlet and outlet pipes are arranged between the first air bag and the second air bag, the two ends of the water inlet and outlet pipes communicate with the interiors of the first air bag and the second air bag correspondingly, the end of the water inlet and outlet pipe connected with the first air bag is arranged on the upper portion of the first air bag, and the water outlet pipes are arranged close to the surface of the bridge floor. A throttling mechanism is arranged on the water inlet and outlet pipe and comprises a conical barrel. According to the technical scheme, the problems that in the prior art, the buffering effect of a pier anti-collision device on collision acting force is not ideal enough, and a pier is prone to being damaged are solved.

Description

technical field [0001] The invention relates to the technical field of bridge anti-collision, in particular to an anti-collision device for a cross-sea bridge. Background technique [0002] With the rapid development of the transportation industry, the number of large bridges spanning navigable rivers, port areas and straits recently built in my country has gradually increased, and the number of ships on the waterway has also continued to increase and the ship types tend to be large, making bridges and ships The contradiction between them is becoming more and more prominent, so the accidents of ships colliding with bridge piers are also increasing. Ship-bridge collision accidents will lead to the loss of life and property, have a serious impact on human activities, social stability and the natural environment, and directly endanger the safety of water transportation, roads, and railways. Serious ones will destroy the ship and bridge, causing heavy casualties and property los...
