Abstract

The invention discloses an offshore grouting auxiliary device and a construction method, and belongs to the field of offshore wind power engineering. The offshore grouting auxiliary device comprises a first plugging piece, a plurality of second plugging pieces and a baffle, the second plugging pieces are arranged on the inner wall of a sleeve in a sliding mode and can slide in the radial direction of the sleeve, when the second plugging pieces are tightly attached to the outer wall of the steel pipe pile, the second plugging pieces plug gaps between the first plugging pieces and the steel pipe pile; the baffle is positioned at the upper end of the second plugging piece, the sleeve, the first plugging piece, the second plugging piece and the baffle define a containing cavity of the outer wall, the grouting pipeline is communicated with the containing cavity, the second plugging piece is tightly attached to the outer wall of the steel pipe pile, an opening is formed in the upper end of the containing cavity, and the containing cavity is communicated with an annular space between the sleeve and the steel pipe pile through the opening. According to the offshore grouting auxiliary device, the second plugging piece is firstly driven to clamp the steel pipe pile, temporary fixing of the jacket and plugging of the grouting bottom are completed, and an operator does not need to dive into water for additional operation.

Description

technical field [0001] The invention relates to the field of offshore wind power engineering, in particular to an auxiliary device for offshore grouting and a construction method. Background technique [0002] Wind energy is a clean and pollution-free renewable energy, so wind power generation is increasingly valued by people. Wind power generation has high requirements on wind power and wind speed, and the construction of wind power facilities on the sea can make full use of the advantages of fast wind speed, stable wind power and no occupation of land resources on the sea. However, the construction of wind power facilities at sea requires the construction of offshore wind power foundations on the seabed first. [0003] At present, in the construction of offshore wind power foundation, the jacket is usually placed on the seabed first, then the steel pipe piles are driven through the sleeve at the bottom of the jacket and driven into the seabed, and finally cement slurry is...
