介绍了一种新型的水泥土搅拌桩成桩方法及其应用,包括测量放线定位、长螺旋钻机就位、长螺旋钻机引孔,以确定桩准确位置,松动硬土层,并排除地下障碍物,然后利用长螺旋搅拌机具边钻进边泵送浆液搅拌至设计孔底标高,重复搅拌和喷浆成桩;在完成搅拌桩施工后,利用长螺旋钻具切割该搅拌桩成孔,压灌混凝土后插入钢筋笼施工护坡桩,形成整体帷幕,达到止水与支护合二为一的效果。 This paper introduces a new method and its application of grouting pile with cement and soil, including the measurement of the pay-off location, the long auger bit in place and the long auger drill hole, so as to confirm the exact position of the pile, loosen the hard soil layer and eliminate the underground obstacles And then use the long spiral mixing machine while drilling into the edge of the slurry pumping to the bottom of the design hole elevation, repeated mixing and spraying into the pile; the completion of the mixing pile construction, the use of long auger cut the mixing pile into the hole, the pressure After pouring concrete into steel cage construction slope protection pile, the formation of the whole curtain, to stop the water and support combined effect.
