| 摘 要： | 传统的疏干管井通常采用负压真空辅助降水,但受到结构密封性的限制,真空度往往不能连续维持.该文针对传统真空管井降水的不足,研究开发一种新型的超强真空降水工法(英文缩写SVD),弥补传统真空管井的不足,大幅度提高降水效果,降低人工劳动强度.

| Abstract: | The traditional water-discharge tube well usually uses the negative pressure to aid the dewatering,but is limited by the structural airtightness.The vacuum degree can not continuously keep.A new super-strong vacuum dewatering process is researched and developed for the shortage of the traditional vacuum tube well,which makes up for the shortage of the traditional vacuum tube well,greatly enhances the dewatering effect and reduces the labor strength of the workers. |
