摘要
根据超前地质预测预报资料,确定了隧道掌子面前方存在高压富水的断裂破碎带,通过对施工地质条件和施工方法的分析,采用全断面超前帷幕注浆技术进行了堵水和围岩加固,从而保证了施工的安全顺利进行。
According to advance geological forecasting report, the following paper determines that there is zone of fracture with high pressure and high water content in front of the palm. Advance drapery grouting technology is used stop water and reinforce surrounding rocks after analyzing the geological condition and proper methods of construction to ensure the construction running smoothly.
