Covering work of back-filled rubble in landfill side
专利汇可以提供Covering work of back-filled rubble in landfill side专利检索，专利查询，专利分析的服务。并且PURPOSE:To prevent damage to a sheet by making the discharge of air and sea water coming into the lower sheet easier by a method in which the upper end of the lower sheet is connected with a dam to form an opening, the lower back- filled rubble is covered with the lower sheet. CONSTITUTION:A lower back-filled rubble 2 for which the lower water level L.WL of the lower top 1 is set is formed on the landfill side 4 of a dam 3. The upper end of the lower sheet is connected with the dam 3 by a rope 10 to form an opening 5, and the lower rubble 2 is covered with a sand-protecting and flexible lower sheet 7. An upper back-filled mass of rubble 11 is formed on the lower top 1 and covered with an upper sheet 20. Air and sea water brought into the lower rubble by the tidal current go into the upper rubble 11 from the opening 5 and are discharged through the aperature between the upper sheet 20 and the lower sheet 7 to the outside. The breakage of the lower sheet 7 due to repeated long-term flapping can thus be prevented.，下面是Covering work of back-filled rubble in landfill side专利的具体信息内容。
