摘要： PURPOSE:To prevent the turbidity of ocean during the construction period of a temporary revetment by a method in which the periphery of a steel framework of a trapezoidal cross section is covered with sail cloth on the sea surface to be reclamated between a breakwater and the main revetment, and sand and gravel are packed into the framework to form a temporary revetment. CONSTITUTION:A temporary revetment 9 is formed between a breakwater 5 and the main revetment 6, in which the periphery of a steel frame 12 formed by vertically connecting many blocks 10 of a trapezoidal cross section is covered with sail cloth 14 and the frames 12 are horizontally connected to form a given reclamating section. Filler 13, e.g., sand or crushed stone, etc., is packed into the blocks 13 to construct a temporary revetment 9. A pollution preventer 11 is provided on the upper end of the revetment 9 to prevent the overflow of pollutants generated during temporary reclamation period over the upper end of the revetment 9. The temporary revetment free of turbidity of sea water can thus be constructed.

摘要： PURPOSE:To form uniform sand layers on soft ground continuously by a method in which a box-like frame whose inside is divided into many small compartments is set on a sheet, sand is packed into the small compartments, the frame is set on the soft ground, and only the frame is pulled up. CONSTITUTION:A sheet S is set on the deck of a working ship, and a box-like frame F having many small compartments 3 whose upper and lower parts are opened by a latticed wall 2 is set on the sheet S. Sand 2 is packed into the compartments 3 and the frame F and the sheet S are hung together by the crane of the working ship and set on soft ground(b). Only the frame F is pulled up by leaving the sheet S and sand on the soft ground. A uniform thickness of sand layer can thus be laid on soft ground and diffusion of sludge during operation can also be prevented.
