结合国内首次引进的全方位高压旋喷注浆工法(MJS)的设备,介绍了设备的构造和施工原理。通过工程试验,对垂直旋喷桩和45°旋喷桩施工进行土体变形和孔隙水压力的监测和分析,为今后在特殊工况下该工法的施工提供了依据。
With the introduction of the first full-scale high-pressure rotary jet grouting method (MJS) equipment, introduced the equipment structure and construction principle. Through the engineering test, the monitoring and analysis of soil deformation and pore water pressure on the vertical jet grouting pile and the 45 ° grouting pile construction provide the basis for the construction of this method in special working conditions in the future.
