Embodiment Construction

[0014] The invention provides an anti-collision energy dissipation ring, which is a rectangular ring-shaped anti-collision energy dissipation ring formed by connecting several energy dissipation units 2 through bolts 3, and each energy dissipation unit 2 is provided with a through hole 4 , the through hole 4 runs through the two sections 5 of the energy dissipation unit 2, and the direction of the through hole 4 is consistent with the structural direction of the energy dissipation unit 2, and a closed loop rope 6 passes through the passage of each energy dissipation unit 2 in turn. Hole 4 connects each energy dissipation unit 2,

[0015] Because the volume and weight of the energy dissipating unit 2 are generally relatively large, the connection strength is not ideal if it is only connected by several bolts 3. In addition, the thread is easy to be ground during use, and the bolt connection will be loosened. However, after the energy dissipation units 2 are connected through th...

Abstract

The invention belongs to the technical field of bridge safety, particularly relates to a pier protection device and discloses an anti-collision energy dissipation ring. The anti-collision energy dissipation ring is formed by a plurality of energy dissipation units which are connected through bolts; every energy dissipation unit is provided with a through hole; the through holes penetrate two sections of the energy dissipation units; the trends of the through holes are in accordance with the structural trends of the energy dissipation units; a closed ring-shaped rope sequentially penetrates the through holes of the energy dissipation units to enable the energy dissipation units to be connected. According to the anti-collision energy dissipation ring, the energy dissipation units can be bound and concentrated in the periphery of the pier through the rope to form into the anti-collision energy dissipation ring when the bolts which are used for connecting and fixing the energy dissipation units lose efficacy due to the fact that the closed rope connects the energy dissipation units, separation of the energy dissipation units is avoided, and the pier is exposed to the exterior.

Description

technical field [0001] The invention belongs to the technical field of bridge safety, in particular to a protective device for bridge piers. Background technique [0002] With the advancement of science and technology and society, the size and tonnage of ships, as well as the density of ships crossing the bridge have increased significantly, and the speed of ships has also increased significantly. Accidents of ships colliding with bridge piers frequently occur. On June 15, 2007, the Jiujiang Bridge in Jiangmen, Guangdong Province was broken by a sand transport ship, and the middle section of the bridge fell about 160 meters into the river completely, causing serious economic losses and casualties. Therefore, more and more attention has been paid to the safety and design of bridge piers. [0003] There are many kinds of anti-collision facilities for bridge piers in the prior art, among which anti-collision energy-dissipating rings are more common, and anti-collision energy-d...
