PROBLEM TO BE SOLVED: To provide a dross covering member, by which a rod is not distorted by the high-pressure injection pressure of solidifying-material slurry, the underwater diffusion of dross is prevented and the solidifying-material slurry is not diluted when dross deposited on the bottom of the water is solidified and treated by a high-pressure jet mixing method.;SOLUTION: The dross covering member 40 used for a high-pressure jet mixing method has a circular or polygonal top wall section 42 with an opening section 46 inserting the rod 30 to a central section, a collar section 44 disposed on the periphery of the top wall section 42 and at least two soil-pressure resistance plates 48 radially disposed towards the collar section 44 from the opening section 46 of the top wall section 42 for inhibiting the distortion of the rod 30 by the reaction of the high-pressure injection energy of a ground curing material.;COPYRIGHT: (C)2004,JPO
