【摘要】 我国地下水污染已呈现从点状污染向带状和面状污染发展的态势,原位钻进注入方法无需开挖、扰动小、成本低,已成为地下水修复的发展热点和方向。本文对国内外功能修复材料原位钻进注入工艺方法和设备进行了调研,重点介绍了直推式钻进注入、喷射注入、压裂注入等工艺方法,总结了各种工艺方法的特点、适用性和局限性,并分析了原位功能材料钻进注入的难点与关键技术,可为该项技术的进一步开发利用提供参考。更多还原

【Abstract】 Groundwater pollution in China has shown a development trend from point pollution to zonal and planar pollution.The in-situ drilling and injection method has become a hot spot and direction of groundwater remediation because it has many advantages such as no open-cut,small disturbance and lower costs.This paper is based on an investigation of in-situ drilling and injection technology and equipment for functional repair materials at home and abroad.At first,it mainly introduces injection with direct push technology,jet injection,fracturing injection and so on.Second,it summarizes the characteristics,applicability and limitations of various methods,and analyzes the difficulties and key technologies of drilling and injection.Finally,it puts forward suggestions for the further development of this technology.更多还原
