DRAINAGE METHOD BY USE OF NEGATIVE PRESSURE OF VACUUM SUCTION AND NATURAL JETTING FORCE

摘要

PROBLEM TO BE SOLVED: To provide a drainage method which is designed to drain water not under water but on water as much as possible with a seawater drainage facility, the method being found accidentally, resulting in the following advantages: there is little difference between work on sea and work on land, repair and addition is simplified, technology progresses quickly, the method contributes to overall progress of underwater power generation, and the amount of discharged seawater and a vacuum suction drainage facility can be simply and strongly enhanced.;SOLUTION: An underwater space part is arranged under a vacuum suction drainage facility, thereby significantly reducing an unnecessary lifting labor part.;COPYRIGHT: (C)2013,JPO&INPIT
