摘要： PROBLEM TO BE SOLVED: To provide an economical multi-layer mat structure dispensing with maintenance and facilitating the purification of bottom sediments in a river and a lake and to provide a purification maintenance method for the bottom sediment. SOLUTION: This multi-layer mat structure 1 for the bottom sediment purification is provided with an intermediate layer including silt 4a having ferric oxide as its main component in an interlayer of a base material composed of a biodegradable sheet or a vegetation mat. In this purification maintenance method for the sediment, the multi-layer mat structure 1 is used instead of a sand covering material and laid on a prescribed region of the bottom. After the sheet for the multi-layer mat structure 1 is fed from a sheet roll unit disposed on a laying pontoon or in water and its end is fixed to the ground, the sheet roll unit is remotely operated, and the multi-layer mat structure 1 is developed and laid on the sediment as covering the bottom sediment, while preventing the dispersion of floating mud.

摘要： PROBLEM TO BE SOLVED: To provide a method of manufacturing a curtain wall which enables execution of manufacture in a narrow place and by one similar form even for several kinds of dimensions. SOLUTION: A form is equipped with a flat base board 51 and the peripheral form 2 that is disposed on the base board 51 and surrounds the periphery of the curtain wall 6 to be manufactured and that can change the dimensions of a sphere to be surrounded. The curtain wall 6 is manufactured by placing a curing material in the form and also disposing a heat insulating three- dimensional wire net. Besides, the curtain wall 6 is manufactured by disposing the form equipped with base board 51 and the peripheral form 2 in a vertical stack in many stage. Since the curtain wall 6 can be manufactured in a plurality in many vertical stages, accordingly, it can be mass-produced even in a place not ensuring a sufficient space. The dimensions of the peripheral form 2 can be changed and therefore the form has a high versatility.
