Pile body sealing device

Abstract

The invention discloses a pile body sealing device. The pile body sealing device comprises a pile shoe, and further comprises an isolation structure and a sealing structure; the isolation structure comprises an isolation piece, and the isolation piece seals one end of the pile shoe; the sealing structure comprises a sealing ring for sealing a gap formed by the pile shoe and a pile body, the interior of the sealing ring is hollow, an inflation pipe is arranged outside the pile shoe, and one end of the inflation pipe communicates with the interior of the sealing ring. Compared with the prior art, the sealing device has the advantages that the sealing ring with the active sealing function can perfectly cope with the problems encountered by the pile body, for example, due to the pile body is not installed in a centering mode, the sealing effect is invalid, seabed surface soil can be effectively prevented from entering a grouting area, the grouting quality is guaranteed, and the sealing effect is excellent.

Description

technical field [0001] The invention relates to the technical field of pile body sealing, in particular to a pile body sealing device. Background technique [0002] The jacket structure is one of the main types of foundation structures for offshore wind turbine foundations, offshore booster station foundations, and offshore oil production platform foundations. top priority. [0003] In practical engineering applications, since the thickness of the sealing ring is slightly larger than the gap between the pile and the sleeve of the grouting sealing device of the booster station, if the eccentric control is not good during the underwater pile insertion process, the pile will directly squeeze the rubber On the one hand, the rubber ring may be damaged, and on the other hand, the gap on one side of the rubber ring may be too large to cause slurry leakage. [0004] Once the grouting device of the booster station fails, measures need to be taken to repair leaks underwater. The con...

Problems solved by technology

[0003] In practical engineering applications, since the thickness of the sealing ring is slightly larger than the gap between the pile and the sleeve of the grouting sealing device of the booster station, if the eccentricity control is not good during the underwater pile insertion process, the pile will directly squeeze the rubber On the one hand, the rubber ring may be damaged; on the other hand, the gap on one side of the rubber ring may be too large to cause slurry leakage

[0004] Once the grouting device of the booster station fails, measures need to be taken to repair leaks underwater, which is extremely difficult to construct and will cause serious economic losses
