同步注浆材料配合比设计与试验研究

Design and Experiment Study of Synchronized Grouting Material Ratio

介绍了工程地质概况、盾构机注浆设备配制情况及施工特点,并依此讨论了同步注浆材料配合比设计和室内试验内容、方法与试验依据。根据室内试验结果选择了同步注浆材料与合理的浆液配合比,根据现场应用中存在的问题进行了优化与调整,取得了经济合理的浆液配合比。

In this article,the author firstly introduces the geologic situation,preparation of the grouting equipment of shield machine,and construction features of the Yuesan section project,and then discusses the synchronized grouting material ratio design,content,method and basis of the indoor experiment.On the basis of the indoor experiment result,he selects scientific and economical synchronized grouting materials and proper material liquid ratio.Finally,according to problems existing in practical application,he optimizes and adjusts the ratio to achieve an economical material liquid ratio.
