Packer device for jacket pile leg grouting and mounting method of packer device

Abstract

The invention discloses a packer device for jacket pile leg grouting and a mounting method of the packer device and belongs to the technical field of ocean platform jacket installation. The packer device comprises jacket leg columns, jacket piles, an upper waterproof sealing piece assembly, a positioning guide block, a spring packing assembly, a bottom packing assembly and the like. According to the packer device for jacket pile leg grouting and the mounting method of the packer device, the upper waterproof sealing piece assembly is arranged on a packer, so that seawater is effectively prevented from entering a jacket pile; the positioning guide block is arranged in the middle of the packer and is guided into a jacket leg column, so that the jacket leg column can be conveniently arranged at a balanced stress position during grouting; the spring packing assembly is adopted, and efficient sealing can be achieved through the elastic force of a spring; the bottom packing assembly is installed on the lower portion of the packer, the seawater on the lower portion can be prevented from entering the jacket pile, and under the first-pile working condition, the jacket leg column can be supported while the bottom packing assembly makes contact with a seabed, and secondary sealing is formed; and the packer device for jacket pile leg grouting and the mounting method of the packer device is reasonable in layout, consumables are reduced, the packing efficiency is effectively improved, and the packer device for jacket pile leg grouting and the mounting method of the packer device has good research significance and research prospects.

Description

technical field [0001] The invention belongs to the technical field of offshore platform jacket installation, and relates to a packer device for grouting jacket legs and an installation method thereof. Background technique [0002] The installation of the jacket of the offshore platform in marine engineering is very important, especially the isolation of seawater in the ocean when the casing is injected into the concrete during the installation of the pile legs and the guarantee of the concentration of the injected concrete are very important. In order to ensure the grouting project The research and development of the jacket leg grouting packer is very meaningful. [0003] The Chinese invention with the application number CN201910491359.6 discloses a tower packer for sealing the cement slurry of the jacket. The tower packer is located between the steel pile and the inner sleeve and the inner sleeve is inserted into the steel pile. During the process, the outer surface of th...
