应用于污染场地原位修复的旋喷工艺研究

Research on Rotary Jet Grouting Technology Applied in Situ Remediation of Contaminated Site

摘要:

从原位修复需求、旋喷技术特点等方面分析高压旋喷注浆技术在污染场地原位修复中的应用前景。根据污染场地原位修复需要，有针对性地对传统二重管法旋喷工艺参数进行改进设计，以提高旋喷技术在污染场地原位修复中的适用性，并开展现场试验研究以验证参数设计合理性，为后续此类工程推广应用提供技术借鉴。

Abstract:

In this paper, the application prospect of high pressure rotary jet grouting technology in in-situ remediation of contaminated site was analyzed in the remediation demand and jet grouting technical characteristics. According to the requirements of the contaminated site in situ remediation, the improved design have been pertinently made on technological parameters of traditional double-pipe rotary jet grouting to enhance the applicability of high pressure rotary jet grouting in situ remediation of contaminated site. Moreover, field test was carried out to verify the feasibility of parameters design and provide technical references for similar projects in future.
