摘要
为探讨洵思区间下穿南水北调干渠克泥效工法运用要点,结合工程实例对克泥效试验段施工及克泥效工法的应用要点进行详细分析,并总结具体的应用效果.结果表明:在下穿南水北调干渠的地铁工程施工中,采用克泥效工法可有效补救在地铁盾构施工中发生的沉降、空洞、喷涌等问题,保证施工的安全性,且成本比较低,使用方便快捷,在地铁盾构施工中可起到止水、充填、支撑等多种效果.可为类似工程提供借鉴.
In order to discuss the key points of the application of the mud control efficiency method in Xunsi section of South to North Water Diversion Project,combined with the engineering example,a brief construction analysis on the mud control efficiency test section is first made,then a detailed analysis on the key points of the application of the mud control efficiency method is made as well,and the specific application effect is summarized.The analysis shows that in the construction of the subway project under the south to North Water Diversion trunk canal,the mud control effect method can effectively remedy the settlement,cavity,gushing and other problems in the subway shield construction to ensure the safety of the construction,and the cost is relatively low.It is convenient and fast to use,and can play a variety of effects in the subway shield construction,such as water stop,filling,support and so on.It is worth using for reference in similar projects.
