multi functional water permeability drainpipe using porous concrete

摘要

The present invention relates to a drainage pipe having excellent water collection and permeability, wherein the entire body portion 13 is composed of porous concrete with a drainage pipe formed of porous concrete having excellent water permeability and a part of the trunk portion 10 composed of conventional general concrete. The permeable layer 14 is formed to be divided into a composite drain pipe having excellent structural stability. The coupling groove 12 and the coupling protrusion 11 are formed to be connected to the other continuum continuous back and forth when connecting a plurality of other structures in the longitudinal direction of the structure, and the characteristics of the installation area according to the rainy season drainage To prevent the swelling of rainwater, and to infiltrate and absorb some of the rainwater, so that the rainwater is absorbed and retained, and maintains the function of flowing during the dry season. It can prevent the flooding of rivers and prevent the desertification of the soil to restore the soil ecosystem and provide a multifunctional permeable drain pipe for artificial drainage and natural drainage.
