SOLIDIFYING TREATMENT DEVICE FOR SOFT GROUND

摘要

PURPOSE:To perform the solidifying treatment work of soft ground with a high accuracy without being affected by wind pressures and tidal waves by providing a spat to be fixed to the supporting ground to a float provided with a treater moving in vertical and horizontal directions. CONSTITUTION:A rope anchored to a given position on the seabed is wound up or sent out by a winch and then moored after moving a float 1. Spats 2a and 2b provided to the float 1 are penetrated into the supporting ground and the float 1 is fixed. The stirring blade 21 of a stirred solidifying treater 7 is penetrated into soft ground layer and vertically moved, and at the same time a base plate is run in the horizontal direction as needed for a solidifying treatment operation over a fixed range. After the ending of the solidifying treatment operation for a desired position, the float 1 is moved to the adjacent position and fixed, and then the same operations are performed.
