当泥水盾构通过岩层破碎带时,块石未经刀具碾磨直接进入土仓,会经常堵塞采石箱、泵、管路等,从而严重影响盾构的掘进。本文通过工程实例介绍泥水盾构过破碎岩带的一些技术措施,以供同仁参考。 When the slurry shield passes through the crust of rock strata, the rock mass directly enters the silo without cutter grinding, and will often block the quarry, pump, pipeline and so on, which will seriously affect the tunneling. In this paper, some engineering measures are introduced to introduce some technical measures of mud-water shield over broken rock belt for reference of colleagues.
