通过滨海地区某深基坑降水工程,重点介绍了截、降结合技术方法在滨海地区深基坑降水中的应用。通过高压旋喷桩截水,坑内外管井降水相结合的方法,成功地达到降水设计要求,并介绍了一些因地制宜的成功经验。 Through a deep foundation pit dewatering project in the coastal area, the application of the technology of cutoff and drop combined with deep foundation pit dewatering in the coastal area is mainly introduced. Through the combination of high pressure rotary jet grouting, dewatering inside and outside the pit and tube wells, the design requirements of precipitation were successfully met, and some successful experiences based on local conditions were introduced.
