Hole, jacket installation are inserted under engineering pile in pilot hole with engineering pile.
A kind of jacket pile pipe pitching pile technique of the present invention, the surrounding of the upper auxiliary stake holes, which is provided on engineering pile, to be oriented to
Slot, and guide groove is corresponded with pilot hole under engineering pile on engineering pile, engineering pile is in guide groove on engineering pile；To
Guide groove carries out guide-localization in utilizing works stake, guarantees to keep vertical perpendicular during engineering pile vertically squeezes into marine rock layer
To insertion.
A kind of jacket pile pipe pitching pile technique of the present invention, the open top end of pilot hole is set as loudspeaker under the engineering pile
Mouthful.
Compared with prior art, the beneficial effects of the present invention are:
The present invention avoids the situation that platform is sunk in ooze by knockdown operation platform and technique, so that
It meets China's sea situation and constructs, and overall structure is simple, is steel construction piece, and cost substantially reduces, and is more suitable for carrying out big
The application of scale reduces site operation cost, improves construction efficiency, facilitates the market competitiveness for increasing construction enterprises.
