Porous bellows that can be used to soil in -situ remediation

The utility model belongs to the environmental engineering field, the porous bellows that can be used to soil in -situ remediation in in particular to washing type soil in -situ remediation field. This porous bellows includes makes the body by carbon steel or alloy constructional steel, the body lie in the intermediate position lateral wall on the equidistance be equipped with a plurality of through -holes, is the diameter of through -hole 3 5mm. Due to the adoption of the technical scheme, the utility model discloses the method provide one kind pollution -free, directional, hang down into local earth in -situ remediation material, compare other restoration method, based on porous corrugated steel pipe's the soil method of restorationing with cheap cost, flexibility control, realize soil in -situ remediation, wide application prospect has. Deformability is strong for corrugated steel pipe geology, and corrugated steel pipe restores the construction period weak point, can carry out batch production production,
