Drilling Rig for Construction of SMWBored Pile Drilling Rig

Drilling Rig for Construction of SMWBored Pile Drilling Rig

Product Features:

 

SMW, which is short of 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.
 SMW method has the following advantages:
1.Low cost. Foundation retaining using SMW method with three-shaft auger machine is much more competitive in price than traditional method when constructing underground continuous wall.
2.Shorter construction period. SMW method consumes much less time than other methods. Under normal geographical conditions, it could build 70-80m² walls per shift.
3.Good seal quality. The wall is continuous without any cracks. Hydraulic conductivity can reach as much as 10-7cm/s.
4.No disturbance in nearby soils. SMW method would not cause hazards like ground subsidence, building inclining, road cracks or shift of underground facilities.
5.Wide range in use. It can be applied on cohesive soil, silt , sandy soil, gravel soil.
6.the waste soil is far less than other construction methods.
