Abstract

PURPOSE:To eliminate the necessity for using a relief valve or the like at pressurization and improve reliability at embedding work of a machine, by erecting a pipe for obtaining required pressure, conducting the pipe into the inside of a casing, utilizing pressure of a head of water filled in the pipe and holding internal pressure in the casing. CONSTITUTION:A pipe 7, having its height required for obtaining embedding pressure, is mounted to a test cylinder 3 of exposed part. A valve 6 is opened, and a hydraulic pump 4 is operated till the filled water has overflowed to come out from the upper part of the pipe 7, thus embedding pressure can be easily obtained. Under this condition, embedding concrete 12 is cast in place. A decreased of pressure due to a fine amount of leak water from an enclosed part can be covered only be supplying water to always overflow from the upper part of the pipe 7, then a load of operating the pump 4 can be decreased, in this way, embedding pressure can be held easily for a long period.
