摘要 介绍了北京地铁五号线某区间暗挖隧道在富水饱和土体中施工时,在隧道地面两侧施做竖向旋喷桩,形成隔水桩墙,结合洞内施做水平旋喷桩形成隔水围幕,最终达到了“改良地层,控制变形;形成隔离,抑制水患;综合治理,保障安全”的目的。 During the construction of a running tunnel on Line 5 of Beijing Metro located in water-rich saturated ground, vertical jet grouting piles are installed on both sides of the tunnel from the ground surface to create water-stopping pile wails and horizontal jet grouting piles are installed from inside the tunnel to create water-stopping curtains so as to consolidate the ground and control the deformation, to create water barriers and eliminate the water risks and to take comprehensive countermeasures and guarantee the construction safety. The construction technology of the described jet grouting piles is presented in the paper.
