深浅孔互补注浆法联络通道施工技术研究

Research on the construction technology of depth hole complementary grouting contact channel

以北京地铁6号线某区间防灾联络通道施工为背景,在富水砂卵石地层条件下,采用了"盾构管片临时支撑,通道深浅孔互补注浆"的综合施工技术,并对地面及联络通道区间进行了监测,证明了深浅孔注浆法可以有效防治地表不均匀沉降和水渗透。

Taking a certain section disaster prevention contact channel construction of Beijing Metro Line 6 as the background,under the stratum condition rich of water sandy cobble,used the comprehensive construction technology of“shield segment temporary support,channel depth hole complementary grouting”,and monitored the ground and contact channel interval,proved that the depth hole grouting could effectively prevention and treatment of uneven surface subsidence and water permeability.
