The present invention belongs to the technical field of offshore wind power construction and particularly relates to a system and a method for sealing expanded polymer-based pile shoes for a jacket. The system comprises a jacket disposed on a seabed, several pile shoes arranged around a lower end of the jacket, and several steel pipe piles inserted into the seabed, wherein the steel pipe piles are inserted into the corresponding pile shoes. The system is characterized in that gaps between the pile shoes and the steel pipe piles are respectively filled with concrete and an expanded high polymer from top to bottom, an annular elastic diaphragm is further connected to the inner walls of the pile shoes, and the expanded polymer is wrapped by the elastic diaphragm, such that the expanded polymer is isolated from the steel pipe piles and the concrete.
A system for sealing expanded polymer-based pile shoes for a jacket, comprising a jacket (3) disposed on a seabed (4), several pile shoes (2) arranged around a lower end of the jacket (3) and several steel pipe piles (1) inserted into the seabed (4), the steel pipe piles (1) being inserted into the corresponding pile shoes (2), wherein the system is characterized in that gaps between the pile shoes (2) and the steel pipe piles (1) are respectively filled with concrete (13) and expanded polymer (10) from top to down, an annular elastic diaphragm (7) is further connected to an inner wall of the pile shoes (2), and the expanded polymer (10) is wrapped by the elastic diaphragm (7), such that the expanded polymer (10) is isolated from the steel pipe piles (1) and the concrete (13).
