Description
Technical Field
The invention belongs to the technical field of bridge protectors, and particularly relates to a rotary floating type anti-collision device for a bridge.
Background
Along with the rapid development of traffic industry, the bridge is largely constructed due to the characteristics of crossing rivers, bringing convenience to the connection of two banks, shortening road mileage and the like, and meanwhile, the development of the water route transportation industry also enables the number and tonnage of ships to be continuously increased. These two factors cause the probability of the ship striking the bridge to be greater and greater, which threatens bridge safety and personnel life on the bridge.
In order to improve the safety of the bridge after the ship collides with the bridge, the existing method mainly comprises two steps, namely reinforcing the self resistance of the bridge pier and arranging an anti-collision device on the bridge pier. The method simply depends on the method of strengthening the self resistance of the bridge pier, so that the economic cost of bridge construction needs to be increased, the saving is not facilitated, and the method still faces the crashed ending.
The existing pier collision avoidance devices are divided into a direct mode and an indirect mode, wherein the direct mode comprises an elastic deformation mode (a buffer material mode and a rope mode), a compression deformation mode (a buffer work mode) and a deflection mode (a gravity mode), and the indirect mode comprises an elastic deformation mode (a pile mode), a compression deformation mode (a caisson mode and an artificial island mode) and a deflection mode (a floating mooring rope mode). The collision-preventing mode of the pier collision-preventing device mostly weakens the impact force brought by ships and the like through the buffer materials, realizes the safety of the pier, and mostly concentrates efforts on the type and form structure of the buffer materials so as to prolong the stress time and reduce the impact force born by the pier. This approach of only setting and changing the cushioning material is impractical to withstand the large impact forces from objects such as boats, which typically reach tens to hundreds of MN, in an effort to completely rely on the cushioning material to withstand the large impact forces as opposed to striking a stone with a pebble.
In addition, the existing bridge pier protection device only removes the protection bridge pier from a single side, is easy to damage a ship passing through, has a certain potential safety hazard, namely the existing bridge pier protection device cannot realize bidirectional protection, and has the defects of high cost and high secondary maintenance cost.
