摘要
在昌马水库排沙泄洪洞大塌方处理中采用了管棚法. 该工法包括回填和固结灌浆、管棚加固、控制爆破和喷锚等工序.本抢险工程成功地穿越了长达 85m、开挖直径达 10m的隧洞塌方段,是隧洞塌方处理技术中的一个突破.
The application of the pipe and strut method in treating large collapses during the flood and sluice tunnel excavation for Changma Reservoir.This method consists of the following procedures: backfill, consolidation grouting,reinforcing by the pipe and strut method,controlled blasting and anchor bars.One tunnel stretch of 85m length and 10m diameter has been successfully driven through with this method. This is an important breakthrough in treating tunnel collapses.
