Zusammenfassung: | To provide an oil recovery system and an installation method of a drain material capable of maintaining a recovery efficiency of oils even when a thickness or a position in a depth direction of an oil layer varies.SOLUTION: An oil recovery system 2 comprises a drain material 3 arranged in the ground 1, a suction hose 5 having one end connected to the drain member 3, and a vacuum suction portion 7 connected to the other end of the suction hose 5. The drain material 3 is divided into drain material 3-1 and 3-2 parallel to a depth direction. The drain members 3-1 and 3-2 are partially formed with water blocking portions 11-1 and 11-2, and the suction portions 9-1 of the drain material 3-1 and the suction portion 9-2 of the drain material 3-2 are different in depth. The suction hoses 5-1, 5-2 are coupled to drain materials 3-1, 3-2, respectively.SELECTED DRAWING: Figure 1
【課題】油層の厚さや深さ方向の位置が変動したときにも油類の回収効率を維持できる油回収システムおよびドレーン材の打設方法を提供する。【解決手段】油回収システム2は、地盤1中に配置されるドレーン材3と、ドレーン材3に一端が連結される吸引ホース5と、吸引ホース5の他端に連結された真空吸引部7とを具備する。ドレーン材3は、深度方向に平行にドレーン材3−1、3−2に区分されている。ドレーン材3−1、3−2の表面には、部分的に遮水部11−1、11−2が形成され、ドレーン材3−1の吸引部9−1とドレーン材3−2の吸引部9−2とは深さが異なる。吸引ホース5−1、5−2は、それぞれドレーン材3−1、3−2に連結される。【選択図】図1 |
