摘要

The anti-crane device for reinforcing soft ground at sea according to the present invention is installed to be fixed by a coupling structure 81 at the tip of the anti-ship vessel 10 such as a barge on which the leader 20 is installed, and a removable sleeve pipe therein. The fixed sleeve pipe 80 having a large diameter so that the 90 can penetrate up and down, and is connected by a wire rope 93 at the upper portion to move up and down along the inside of the fixed sleeve pipe 80, and a casing therein. The pipe 30 is characterized in that it comprises a sleeve structure consisting of a movable sleeve pipe 90 which serves to protect the casing pipe by moving up and down. The sleeve structure is a means for fixing the movable sleeve pipe 90, a hydraulic fixing device 92 is installed above the fixed sleeve pipe (80).
