Descriptionof SMW (Soil Mixing Wall):
SMW is the abbreviation of soil mixing wall, this foundation technology isapplied to build secant and retaining wall.

Procedureof SMW (Soil Mixing Wall):
1. Three shafts soil mixing rig has to be used to drill the certain depthaccording to the design, the multi shaft augers can blended the soil and injectthe concrete formula into the bore pile.
2. Each unit of bore pile has to be secant, finallythe continuous underground wall can be built.
3. Before the cement setting, the H beam need to beinserted into the soil mixing wall to reinforce the wall.
4. After the cement setting, the soil mixing wall will be continuous, highstrength, and water tight underground wall.
5. After finish the complete construction, the H beam can be removed from thecontinuous wall to use again at the next site or either remains there as thecontinuous wall to be used.

Advantageof SMW (Soil Mixing Wall):
Very much less vibration to the surroundings, the following circumstances canbe avoided: ground sink, building inclining, and road break etc comparing tothe traditional underground continuous wall.
Higher water tight level, the coefficient of permeability is 10-7 to 10-8CM/s
H beam can be reused again and again for the temporally underground continuouswall. It will be very much cost efficient and environmental friendly.
