Water-permeable divided gutter

Abstract

Abstract PURPOSE:To obtain a water-permeation type divided block which changes acidic rain to weak acidic rain by vertically dividing the inside by a partitioning plate having an opened port part and accommodating the broken stones containing alkali into the lower space and forming a water-permeable hole in the lower part of the side wall. CONSTITUTION:The inside of the side wall of a divided block 1 which possesses the water collecting function and is used as drain pipe is divided by a connecting plate 4 having an opened port part 13, and a space 5 is formed vertically. The broken stones consisting of igneous rocks containing limestone and alkali are accommodated into the lower space 5, and a water-permeable hole 7 is formed in the lower part of the side wall. The upper space 5 is covered by a cover 12, and connected with a rain-water introducing pipe. Therefore, the acidic rain can be changed to weak acidic rain, and the soil improving effect can be secured.
