Title:
地盤の透水性を低下させる方法
Document Type and Number:
Japanese Patent JP3600892
Kind Code:
B2
Abstract:
To provide a method for lowering the water permeability for the purpose of spring water prevention of the sand ground or gravel ground and improvement of the weak ground.
Two or more kinds of aqueous solutions which permeate easily into the sand ground or the gravel ground, i.e., an aqueous solution containing + bivalent or + trivalent iron ions, and an aqueous solution which oxidizes it, are simultaneously or separately poured into the ground and mixed to react in the ground. Fine deposits sparingly water-soluble are thereby produced in the ground to lower the water permeability of the ground.
