Abstract
PURPOSE: To purify running water in a stage where the water flows through a drainage canal by laminating a subbase work as the lowest layer, a purifying stone layer as an intermediate layer or a top layer, or a water permeable cement concrete layer as a top layer or an intermediate layer. CONSTITUTION: Subbase soil consisting of simple grain crushed stone No.6 is formed as a foundation layer, on which SD light is spreaded all over as an intermediate layer. Then for the top layer, portland cement of 300 to 400 kg per 1 m<2> of cement concrete mixture, 0.008 to 0.04 wt.% of a binder and 0.3 to 0.45 wt.% of water per 1 wt.% of cement and, for the remaining portion, an aggregate having sand and No.7 crushed stone of 5:95 to 20:80 in wt.% is mixed. The mixture thus obtained is flowed or cast molded and a water permeable cement concrete layer solidified is obtained. In this way, effective utilization of wastewater or the like flowing through the drainage canal can be made extremely easier.
