Abstract:
PROBLEM TO BE SOLVED: To provide a method of removing organic matter in a removed submarine sludge containing an organotin compound, which is carried out at the same time when the high-water-content dredged soil containing the organotin compound is separated into surplus water and earth and sand and the organotin compound is removed from each of the separated surplus water and the separated earth and sand. SOLUTION: This method includes a step to convey the high-water-content dredged soil containing the organotin compound to a flocculating/settling basin 5, a step to add a flocculant to the basin 5, agitate the dredged soil with the added flocculant and separate the dredged soil into earth and sand, flock-settled sediments and seawater, a filtration step to supply the separated seawater and floating flocks to a sand filtration tank and an activated carbon adsorption tank 9 and remove the suspended matter and the organotin compound contained in the separated seawater, a step to withdraw the earth and sand and the flock-settled sediments from the basin 5 and dry them, and further, a step to stick the organotin compound in the floating flocks of a fixed amount of the organotin compound contained in the dredged soil to a polyethylene sheet 7, which is carried out before the filtration step.

PROBLEM TO BE SOLVED: To provide a form panel for coating an existing structure and a coating method for the existing structure coating method capable of easily carrying out repair of the surface part of the existing structure by a laminated sheet, maintenance and repair of the external appearance or the like with high degree of accuracy. SOLUTION: The form panel 1 for the existing structure coating is so constituted that a projection 11a consisting of an attachment or a transplantation type fibrous material, a mesh of knitting fabric and a mineral particle or a synthetic resin particle is provided to the inside and that the outside of the laminated sheet 1a consisting of a resin layer 11 fixed to the existing structure in a state to closely fill the circumference of the projection 11a with a hardener (without being illustrated) and a coating layer 12 having one or more layers fixed to the outside of the resin layer 11 through an adhesive and having the outermost layer with a stain-proof function is stuck on the inside of the usual form panel 1b in a detachable manner.

PROBLEM TO BE SOLVED: To provide a laminated sheet for covering a structure, which can maintain an appearance by preventing the deterioration of the structure over a long period of time after covering the structure. SOLUTION: This laminated sheet 1 for covering the structure (not shown in the figure) includes: a synthetic resin layer 11 inside which protrusions 22, composed of a transplanted bristle-like fiber material, are provided and which is fixed to the structure in a state in which a solidifying material 15 is infilled around the protrusions 22 with no space in between; and at least one coating layer 12 which is fixed to the outside of the layer 11 via an adhesive and whose outermost layer has a stainproof mechanism.
