Ice-resisting and wave-dissipating device for pile column

Abstract

The invention discloses an ice-resisting and wave-dissipating device for a pile column. The ice-resisting and wave-dissipating device comprises an upper cone and a lower cone which are in upper-down symmetric, wherein a sleeve is arranged at the central positions of the upper cone and the lower cone; the top of the sleeve is connected to the top of the upper cone; the bottom of the sleeve is connected to the bottom of the lower cone; the middle part of the sleeve and the buckled part of the upper cone and the lower cone are welded and fixed by a supporting plate; through holes are formed in the upper cone, the lower cone, the sleeve and the supporting plate; a wave dissipating chamber is jointly formed by the upper cone, the lower cone, the sleeve and the supporting plate; by using the slopes of the surfaces of the upper cone and the lower cone, the condition that sea ice is bent and damaged when the upper cone and the lower cone and the sea ice mutually act is avoided.

Description

technical field [0001] The invention relates to an anti-icing device for marine structures in ice regions, in particular to an anti-icing and wave-eliminating device installed on piles. Background technique [0002] In low-temperature sea areas, a large amount of sea ice is formed every winter. Sea ice drifts across the ocean's surface under the influence of tides, currents and winds. Drifting sea ice exerts compressive forces on marine structures when it encounters them. In areas with serious sea ice, the sea ice load is the control load in the design of marine structures, which poses a great threat to the safety of marine structures. In order to reduce the effect of ice load, the current common measure in the engineering field is to install ice-resistant cones on the piles of marine structures. The traditional anti-ice cone is a combination structure of forward cone, inverted cone or forward inverted cone, and the surface of the cone is usually closed. This structural ...

Problems solved by technology

In recent years, some scholars have begun to study the anti-ice cone structure with wave dissipation function. The cone adopts a number of inclined struts to replace the original closed surface. Although this structure reduces the effect of wave load to a certain extent, due to The gap between the struts is large, which often causes drift ice or floating objects on the sea to "block" the gap of the cone, thus affecting the anti-ice or wave dissipation effect
