Anti-collision method and device for isolated double protection pier with auxiliary pier

Abstract

An isolated double protection bridge pier anti-collision method and device with auxiliary piers, on both sides of the bridge pier, one or more auxiliary piers are arranged on both sides of the bridge pier along the bridge direction, the anti-collision device is installed on the auxiliary pier, the anti-collision device is not connected with the auxiliary pier The protected pier acts directly to prevent the impact force from being directly transmitted to the protected pier, and the main body of the anti-collision device adopts a buoyant structure, which can float up and down with the change of the water level, and can give sufficient protection in the vertical direction of the main pier; the use of the anti-collision device The anti-collision double protection for the protected pier is achieved by itself and the auxiliary pier; and guide wheels are installed at both ends of the outer anti-collision buoyancy tank. When the ship is colliding with the end of the anti-collision device, the guide wheel can adjust the direction of the bow to disperse the impact force , to protect the pier while reducing the damage to the anti-collision device. The invention is an anti-collision device for bridge piers with sufficient protection for bridge piers, elegant appearance, small occupied water area, low cost, easy installation and maintenance.

Description

technical field [0001] The invention relates to a bridge safety protection method and device, in particular to an isolated double protection bridge pier anti-collision device used for auxiliary piers with protective belts. Background technique [0002] With the construction of a large number of bridges in waterway and land transportation, the possibility of ship-bridge collision accidents is also increasing. Once a ship-bridge collision occurs, it is likely to cause a series of serious consequences such as bridge collapse, ship destruction and human death, and environmental pollution. When a large ship hits a bridge pier at a certain speed, according to the momentum theorem, due to the extremely short collision time, the instantaneous impact force is quite large. Blindly relying on thickened pier "hard resistance" is neither beautiful nor economical. Building anti-collision piers has limited effect, and it is difficult to repair after collision damage.
