土体加固高压旋喷灌浆工艺试验

Construction Technology Test for High Pressure Jet Grouting of Soil Reinforcement

穿黄工程北岸竖井土体加固采用高压喷射灌浆施工方案,加固深度超过50 m,设计指标严格,合理选用高压喷射灌浆施工工艺和施工技术参数十分关键。介绍了新三管法和双高压浆液三管法等高喷灌浆工艺方法的试验施工情况、质量检查和试验成果,以及对试验成果进行的分析和评价。

The north bank shaft across the Yellow River project adapts the construction technology of high pressure jet grouting for soil reinforcement, and reinforced depth is over 50m. It is crucial to select reasonable construction technology of high pressure jet grouting and technological perimeters. The paper introduces the construction technology test and construction condition of high pressure jet grouting for new three-pipe method and double high pressure three-pipe jet grouting, then describes quality examination and test findings, and evaluate the test result.
