摘要
Abstract
The vertical shaft of Xianglushan Tunnel in Dali Section I of Central Yunnan Water Diversion Project is a newly added passage.The vertical shaft passes through dolomite limestone and andesite basalt from top to bottom,with prominent problems of karst water inrush and seepage,and high external water pressure.By using directional drilling to implement ground pre grouting for advanced water blocking and reinforcement of the vertical shaft,the safe and rapid excavation of the vertical shaft is ensured.The vertical shaft of Xianglushan Tunnel is constructed using 600m directional drilling.Currently,all drilling has been completed,and the inclination deviation is controlled within 3‰.The technology is feasible and the economic benefits are good.关键词
