METHOD FOR CONSTRUCTING PERMEABLE PURIFICATION BODY AND GROUNDWATER COLLECTION STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a method for constructing a permeable purification body in which a tubing material disposed in the body does not easily move.SOLUTION: A method for constructing a permeable purification body P comprises: an excavation step of forming a vertical shaft 9 in the ground containing contaminated groundwater W; and a filling step of filling the vertical shaft 9 with a purification material 1 for purifying contaminated groundwater W, and installing a tubing material 3 for collecting the groundwater and a support member 2 holding the lower end portion of the tubing material 3 in the vertical shaft 9. The filling step comprises: a first step of filling the purification material 1 to the installation height of the support member 2; a second step of placing the support member 2 on the upper surface of the purification material 1 filled in the first step; and a third step of filling the purification material 1 on the support member 2.SELECTED DRAWING: Figure 2
