岩土施工技术在污染场地治理中的应用研究

Study on Application of Geotechnical Construction Technology in Contaminated Site Management

摘要:

本文介绍了采用高压旋喷注浆法和深层搅拌法在南京燕子矶传统老工业集中地区大面积、大深度、重污染场地治理的机理、工艺、施工要点和使用的施工机械、主要参数等。工程实践证明，采用这2种岩土施工技术治理污染场地，质量高、效果好、工期短、投资低，值得推广应用。分析了存在的问题，提出了进一步研究完善的建议。

Abstract:

This paper introduces the mechanism, process, key construction points and construction machinery as well as main parameters in large area, large depth and heavy contaminated site management by high pressure rotary jet grouting and deep mixing methods. The engineering practice proved that these two geotechnical construction technologies have advantages of high quality, good effect, short duration and low investment. The existing problems in the construction were analyzed with suggestions for further study.
