| 摘 要： | 钻斗钻机具有孔内直接旋挖取土、快速穿越卵石土层和强风化岩层的功能，配上汽车潜孔锤和全套管跟进，可快速嵌入岩层。若同时采用优质泥浆护壁、气举反循环清渣、履带吊车一次吊放长钢筋笼和大料斗灌注桩身砼等工艺，则完全可实现优质、高速钻孔成桩。

| Abstract: | Funnel drilling machine has following functions such as spiral excavating soil directly in the hole, piercing through cobble stone and weathering strongly rock layer, if matching hidden hole hammer of automobile and complete set tube, drilling machine can embed in the rock layer. Meanwhile if high quality muddy wall-protection, anti-circulation cleaning by air, creeper crane hanging and putting long steel reinforcement cage once can be used, high quality and high speed drilling to pile can be realized. |

| Keywords: | funnel drilling machine cobble stone layer swiftly embedding into rock anti-circulation cleaning sediment by air |
