盾构空推过矿山法隧道施工工法是一种适用于盾构机通过中风化、微风化、未风化硬岩段地层时的隧道施工工法。该工法应用于城市地铁隧道施工时,在地铁隧道线路上方地面没有障碍物的情况下,结合地面灌浆空隙充填技术,能够显著提高盾构管片的防水效果,大大改善隧道施工质量。该工法由深圳市市政工程总公司、中铁隧道集团有限公司编制,并通过了广东省住房和建设厅组织的成果鉴定,被批准为2013度
The construction of a hollow tunnel through the mine method is a suitable method for tunnel construction when the shield passes through weathered, slightly weathered and unweathered hard rock formations. The method is applied to the construction of urban subway tunnels. When there is no obstacle on the ground above the subway tunnel line, combined with the filling technology of ground grouting voids, the method can significantly improve the waterproof effect of the shield tunnels and greatly improve the construction quality of the tunnels. The method by the Shenzhen Municipal Engineering Corporation, China Railway Tunnel Group Co., Ltd. prepared by the Guangdong Provincial Housing and Construction Department of the results of appraisal organized and was approved as 2013 degrees
