Driven type single-column and single-pile offshore anemometer tower foundation

Abstract

The invention discloses a driven type single-column and single-pile offshore anemometer tower foundation comprising a lower steel pile and an upper block, wherein the lower steel pile comprises a soil foundation steel pile and a transition tapered section with a large-diameter lower part and a small-diameter upper part; the small diameter of the upper part of the transition tapered section is connected with the diameter of a stand column at the bottom of the upper block in a matched manner; the top of the transition tapered section is provided with a driving section and the driving section is connected with a pile hammer; a deck is arranged at the top of the upper block; the upper block comprises a single-column structure and an inclined strut structure; the upper end of the single-column structure is connected with the deck and the lower end of the single-column structure is connected with the small diameter of the transition tapered section; the deck is provided with four deck stand columns and the inclined strut structure is a four-inclined-strut structure; four inclined struts are supported on the stand columns and are connected with the four deck stand columns; flange discs are arranged at the tops of the four deck stand columns; and the flange discs are connected with an upper anemometer tower frame. The driven type single-column and single-pile offshore anemometer tower foundation has the advantages of simple structure, low construction resource requirements, easiness for installation, short construction period and easiness for forming standardization, can be suitable for different sea areas through adjusting a pile diameter and a pile length, and can be popularized and applied to a plurality of sea areas.

Description

technical field [0001] The invention relates to the technical field of offshore wind-measuring towers, in particular to a driven-in type single-column, single-pile offshore wind-measuring tower foundation. Background technique [0002] At present, the offshore wind-measuring towers that have been implemented in China all adopt the truss-type wind-measuring tower structure, and their foundations are all high pile caps, which are mainly composed of steel piles, horizontal and oblique supports, and conversion decks. The foundation generally has three to four steel inclined piles, and the steel piles are composed of the foundation section into the mud and the riser section above the mud surface. The horizontal and diagonal supports are located above the water surface, and the top of the steel piles is the transfer deck. This type of structure has strong overall stability, but offshore construction is complicated. The driving of steel piles requires a professional piling ship to...
