Floation type section-changeable bridge-pier/tower column anti-collision device

Abstract

The invention discloses a floating variable-section pier / tower pile anticollision device, especially relating to a floating anticollision device able to protect variable-section piers / tower piles, where an anticollision body is separated into two left and right independent box bodies between which there is at least a guiding component running through vertical dividing surface and forming dynamic connection that the box bodies goes up and down with water level and are disconnected and connected at the dividing surface, and the two box bodies are connected into a whole, and the two box bodies slide along the outer surfaces of the protected piers / piles and always surround the protected piers / tower piles; and the guiding component is composed of guide pile and guide sleeve; the positions of the inner surfaces of the two box bodies corresponding to the outer surfaces of the piers / piles are equipped with isolating components. And the invention has features of reasonable design, simple structure and achieving remarkable technical effects. And it can be applied to anticollision protection to various variable-section piers / tower piles. And it can prevent the sailing ships or other floaters from colliding piers / tower piles, having long service life and convenient to maintain and repair.

Description

technical field [0001] The invention relates to a floating anti-collision device, in particular to a floating anti-collision device capable of protecting bridge piers / towers with variable cross-sections. Background technique [0002] At present, most of the bridge piers / towers in the existing domestic navigable rivers are not equipped with anti-collision devices. They only try to prevent the piers / towers from being located in navigable waters or restrict navigable ships, or even increase the height of the piers / towers. The impact resistance of the column itself is used to prevent collision damage. These methods place additional constraints on the design of navigable vessels and bridges, and there is still a risk of damage to piers / pillars in the event of a collision in which the constraints fail. In the existing bridge pier / tower column anti-collision technology, there are already anti-collision protection devices for equal-section bridge piers. Since variable cross-sectio...

AI Technical Summary

Problems solved by technology

Since variable cross-section piers / pylons have Y-shaped, inverted Y-shaped, A-shaped, vase-shaped, etc., it is more difficult to protect variable cross-section piers / pylons in waters with high water level drop and narrow channel waters. Floating anti-collision devices without protection for variable cross-section piers / pillars
