以赣江堤防工程金滩堤段高喷钻灌施工为背景,通过高喷钻灌一体机在砂砾石及粉砂地层中钻孔灌浆的应用所反应出来的三个技术难题,结合自己的工程实践,提出了高喷一体机在类似地层中严重制约钻孔及喷浆的施工处理措施,为类似地层高喷一体机应用提供了良好的借鉴。本项目的处理未见国内外相关资料或报道,仅供其它类似工程参考。 Taking the high jetting and drilling construction of Jiantan section of Ganjiang embankment project as the background, three technical problems that are reflected by the application of drilling grouting in sand, gravel and silt formations by high jetting and drilling integrated machine are analyzed. Combined with their own engineering Practice and put forward the construction and treatment measures of the high jetting one machine that seriously restrict the drilling and shotcrete in similar stratum and provide a good reference for the application of similar stratum high jet integrated machine. The project has not been dealt with relevant information or reports at home and abroad, only for other similar projects.
