Offshore grouting leakage preventing structure and method
The invention discloses an offshore grouting leakage preventing structure and method. The offshore grouting leakage preventing structure comprises a grouting outer pipe, a grouting inner pipe and a sealing partition plate, wherein one end of the grouting inner pipe stretches into the grouting outer pipe, an annular grouting channel is formed between the outer wall of the grouting inner pipe and the inner wall of the grouting outer pipe, a seal ring used for sealing and blocking the grouting channel is arranged between the grouting inner pipe and the grouting outer pipe, the sealing partition plate is arranged at one side, away from the grouting channel, of the seal ring and provided with at least one vent hole, and a net-shaped grid is arranged in each vent hole. The offshore grouting leakage preventing method includes the following steps that the seal ring is fixed outside the grouting inner pipe; the sealing partition plate is fixed in the grouting outer pipe; after pile sinking of the grouting outer pipe reaches the design elevation, the grouting inner pipe stretches into the grouting outer pipe and grouts mortar into the grouting channel. The offshore grouting leakage preventing structure and method can effectively ensure smooth construction of an offshore wind turbine foundation.
