SEMI-WATER PERMEABLE IMPERVIOUS PLATE WITH CLEANING FUNCTION, GROUND WATER CLEANING STRUCTURE, AND CONTAMINATED GROUND WATER CLEANING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a semi-water permeable impervious plate with a cleaning function, which plate has functions of both of a water impermeable wall and a cleaning wall and can control three, i.e., cleaning, flow velocity and flow direction of contaminated ground water, a ground water cleaning structure disposed therewith in the ground and a cleaning method for the contaminated ground water using the same. SOLUTION: The semi-water permeable impervious plate is annexed with a cleaning section 2 packed with cleaning materials 5 in a frame 6 in at least a portion of one surface 16 of a substrate 1, in which the impervious plate provided with a first aperture 3 for inflow or outflow of the ground water on the surface 15 of the substrate 1 facing the cleaning section 2 and provided with a second aperture 4 for inflow or outflow of the ground water in the frame 6 of the cleaning section 2 is built like a continuous wall into the ground.
