快速钻机在隧道施工地质预报中的应用研究

在隧道工程开挖阶段施工中,如何能提前预报前方地质情况,从而采取有效的施工方案,能最大限度地规避隧道施工事故的发生。目前我国预报手段主要分为为物探和钻探。物探和钻探各有利弊:物探速度快,但是易受到周边环境的影响;钻探速度较缓慢,影响施工进度较明显。经过大量的比较,在小断面施工条件下,使用RPD-150C快速钻机,可以较好地解决钻机钻进速度慢、自动化程度不高的问题。

Application of Fast Drilling Machine in Tunnel Construction Geological Forecast

In the excavation period of the tunnel engineering,forecasting the geological condition so as to carry out an effective construction plan can avoid tunnel construction incidents at the utmost degree.At present,our country's forecasting methods are geophysical prospecting and drilling.Each has its merits and drawbacks: geophysical prospecting is fast but fragile to the influence of environment;drilling is slow and affects the construction process.Through a large amount of comparisons,in small section constru...
