¡ï SMW drilling machine
SMW, which is short for Soil Mixing Wall, is a construction method developed in Japan in 1976. Now it consists 50% of underground continuous wall constructions in Japan, and widely adopted in countries in southeast Asia, the United States, France etc. In Shanghai, Hangzhou, Nanjing and other cities of China, SMW becomes quite popular after its introduction years ago.
SMW uses multi-shaft auger to drill soil in situ, meanwhile pumps cement grout from the tips of the augers into the drilled holes. After sufficient mixing of the grout, H-shaped steel or other types of steel are embedded into the columns before the soil-cement mixture hardened, forming a underground continuous wall with rigidity and intensity. The wall could be used as retaining support or water seal. Three-shaft auger machine is commonly used.
