浅谈气幕法沉井在防汛排水工程中的应用

Brief Talk about Application of Air Screen Method Sunk Well in Flood Control Drainage Engineering

结合工程实例对气幕法沉井工艺有效减低井周土体扰动的原理,有利于减少沉井工程周边管线与构筑物搬迁,降低沉井工程的成本等优势及该工艺的应用进行分析和探讨,总结了一些经验,认为该工艺是在城市化地区沉井施工中一种值得采用的施工措施。

In the combination with the project example the paper analyzes and approaches to the following aspects: the principle of effectively reducing soil body disturbance around well by air screen sunk well process; the advantages such as to help improve reducing removal of piping and structures around sunk well project, to reduce the cost of sunk well project etc. as well the application of the process. It also summaries some experience and thinks that the process is a construction measure used in sunk well construction of citified area.
