介绍已引进和准备引进的二种日本高压喷射注浆工艺,和已引进的MJS工法在上海的应用情况。考察这二种先进高压喷射注浆工艺的工艺原理、技术参数和施工设备,并与国内常用高压喷射注浆工艺比较。这二种先进工艺在传统工艺基础上做的改进,从不同角度提高了高压喷射注浆工艺的施工能力,拓宽了其应用范围,能更好地满足工程建设的需要,研究此二种工艺可为今后的工程建设提供参考和借鉴。
Introduce the two kinds of high-pressure jet grouting technology introduced and prepared for introduction in Japan and the application of the imported MJS method in Shanghai. Investigation of these two kinds of advanced high-pressure jet grouting process technology principles, technical parameters and construction equipment, and compared with the domestic high-pressure jet grouting process. The improvement of these two kinds of advanced technology on the basis of traditional technology has improved the construction capability of high-pressure jet grouting technology from different angles, broadened the scope of its application and better meets the needs of engineering construction. The two kinds of processes can be studied For the future construction of the project to provide reference and reference.
