摘要
A fluid extraction well comprising a wall body made of porous media with multiple pores for remediation of contaminated underground space is provided to make it difficult for fine soil to penetrate into the well in a process of injecting and penetrating a fluid into a suction well, and to reduce a pore closing phenomenon substantially by greatly increasing the area of the well contacted with soil as compared with a conventional well. A fluid extraction well or a fluid injection well used in a process for in-situ remediation of contaminated underground space comprises manufacturing steps of: (a) manufacturing a cylindrical wall body with variable sized pores by using a porous media with a large pore size as a material for an outer wall body and by using a porous media with a small pore size as a material for an inner wall body; (b) sealing upper and lower ends of the cylindrical wall body manufactured in the step(a) with lids respectively; and (c) installing a fluid extraction pipe on the upper lid that has been installed in the step(b) to form a fluid extraction well or a fluid injection well.
