    • PROBLEM TO BE SOLVED: To achieve the improvement of landfill disposal efficiency and laying ease, the shortening of a laying period, the saving of a laying cost, and the like, by suppressing to a low level effects of a hydrostatic pressure due to a difference in the water level between the inside and the outside of an impervious structure, and the water pressure due to waves.
      SOLUTION: The sea surface waste disposal yard utilizes an inner water area B closed by a sea wall 2 as a landfill disposal area 1 of waste, and has the impervious structures 8 and 10 including an impervious sheet laid on the sides and bottom face of the inner water area B. A submersible pump 12 and a water pressure sensor 13 are buried near the slope base of the sea wall 2. When the water pressure increases near the slope base of the sea wall 2 due to a rising tide level or wave effects in the outer water area, the submersible pump 12 is activated in accordance with a signal from the water pressure sensor 13 to forcibly discharge to the sea the brine which penetrates the sea wall 2, a sea bottom terrain 3, or the like gradually reaching the back of the impervious structures 8 and 10. Thus, the water pressure applied by the hydrostatic pressure and the wave force acting upon the impervious structures 8 and 10 is reduced to stabilize the structures 8 and 10.

    • 要解决的问题:为了达到提高垃圾填埋场处置效率和放置容易度,缩短铺设期间,节省敷设成本等,通过抑制由于流体静力压力的低水平影响 对于不透水结构的内外的水位差和由于波而产生的水压差。 解决方案:海面废物处理场利用由海墙2封闭的内水区域B作为废物的填埋处理区域1,并且具有不透水结构8和10,其包括放置在侧面和底部的不透水板 内部水域B的表面。潜水泵12和水压传感器13被埋在海墙2的斜坡底部附近。当由于潮汐水位升高而在靠近海墙2的斜坡底部的水压力增加时 或波浪效应,潜水泵12根据来自水压传感器13的信号被激活,强制地向海中排放穿过海墙2,海底地形3等的盐水 逐渐到达不透水结构8和10的背面。因此,通过静水压力施加的水压力和作用在不透水结构8和10上的波浪力减小,以稳定结构8和10.版权所有( C)2004,JPO
