Ice-resistant structure of single column foundation

Abstract

The invention discloses an ice-resistant structure of a single column foundation. The ice-resistant structure comprises a single column, a large diameter column, a plurality of ice-resistant pieces, afirst suction barrel foundation, a plurality of second suction barrel foundations, a shaft sleeve, a plurality of spring rods and a plurality of stability-enhancing floating barrels, wherein the first suction barrel foundation is arranged at the bottom end of the single column; the large diameter column is arranged at the upper end of the single column; the plurality of ice-resistant pieces are uniformly distributed in the periphery of the large diameter column; the ice-resistant pieces are connected to the periphery of the large diameter column; the ice-resistant edge, far from the large diameter column, of each of the ice-resistant pieces is composed of two concave arc-shaped sections; rhombic shock absorbing holes are formed in the main body of each ice-resistant edge; the shaft sleeveis arranged on the single column concentrically and is separately connected to the plurality of second suction barrel foundations uniformly distributed in the periphery of the first suction barrel foundation through the spring rods; and the plurality of stability-enhancing floating barrels are uniformly distributed in the periphery of the single column and are connected to the single column through arms of force. The ice-resistant structure disclosed by the invention is simple and novel in structure, and the impact force of sea ice to a petroleum platform can be reduced effectively.

Description

technical field [0001] The invention relates to an ice-breaking structure on the sea surface, in particular to an anti-ice structure with a single column foundation. Background technique [0002] Sea ice is a complex mixture composed of solid ice, brine, air, etc. Its physical and mechanical properties are mainly controlled by many factors such as temperature and salinity, and its interaction with structures is extremely complicated. The safety of the structure poses a serious threat. Driven by marine environmental factors such as wind and current, a large area of ​​sea ice can produce a continuous and huge extrusion effect on vertical structures. [0003] The single-column single-pile foundation (hereinafter referred to as the single-pile foundation) is usually composed of a single steel pipe with a diameter of more than 4m. The lower part of the single-pile foundation goes deep into the soil to provide bearing capacity; It is connected to the fan tower through the groutin...
