综合防治水技术在立井井筒掘进中的应用

Application of Comprehensive Water Control Technology in Driving Vertical Shaft

立井井筒掘进过程中产生涌水,水压较大,竖向裂隙较发育,注浆堵水难度大,严重影响施工安全和施工进度。通过采用综合防治水技术,严格执行“有疑必探、先探后掘”,采用防、堵、排、截的综合治理原则,实现了立井井筒过强含水层的安全、高效施工,同时取得了很好的经济效益。

Aiming at the serious influence of high water pressure,developmental vertical crack and difficult sealing grouting caused by water inflow on construction safety and progress in driving vertical shaft,the paper presents the comprehensive water control technology with principle of"detecting with doubt and driving before detecting"followed strictly together with"prevention,sealing,drainage and interception",which can realize the safety and efficient construction in crossing strong aquifer with good economic benefits.
