STUDY ON GROUND CONDITION FOR EARTHQUAKE-PROOF ADAPTABILITY OF WATER SERVICE PIPELINE

Abstract

It is important that making the water service pipeline earthquake-proof provide the priority level. It is in the situation to which the water-supply corporation is worrying about the judgment of so-called'Good the ground' intended for the underground water service pipeline. This paper focuses on earthquakeproof adaptability of ductile cast iron pipe with K-type joint. The relation between the damage during the recent severe earthquakes and ground condition was examined. The ground condition that earthquake-proof adaptability of ductile cast iron pipe with K-type joint is recognized was clarified.
