Tower packer for packing cement slurry of jacket

A tower packer for packing cement slurry of a jacket located between a steel pile and an inner sleeve, comprising:

• a supporting ring, a plurality of sealing rings, a waterproof skin, and a limiting ring, wherein the supporting ring and the limiting ring are installed on an outer surface of the inner sleeve in the steel pile,
• the plurality of sealing rings stacked from top to bottom along a sleeving direction of the inner sleeve are arranged between the supporting ring and the limiting ring,
• each of the plurality of sealing rings is hermetically and slidably connected along a radial direction,
• a bottom sealing ring at the bottom of the plurality of sealing rings is affixed to and supported by the supporting ring,
• a top sealing ring at the top of the stacked plurality of sealing rings is affixed to a lower surface of the limiting ring, and
• wherein, in operation, the inner sleeve is inserted into the steel pile, an outer surface of the sealing ring with a maximum outer diameter hermetically abuts against an inner surface of the steel pile, and the sealing rings between the top sealing ring and the bottom sealing ring slide to adapt along the radial direction as a distance between the outer surface of the inner sleeve and the inner surface of the steel pile changes, and
• wherein the waterproof skin is annular in shape, an outer edge of the waterproof skin is hermetically connected to the inner surface of the limiting ring, and an inner edge of the waterproof skin is hermetically connected to the sealing ring with the maximum outer diameter or hermetically connected to the sealing ring having a minimum outer diameter.
