Mechanical wet deep soil mixing In Keller's deep soil mixing method a special mixing tool is inserted into the soil on site. This mixing tool comprises a drilling rod, transverse beams and a drill end with a head. The drilling causes no vibrations, and is assisted by cement slurry outflow from nozzles purposely located at the end of the soil ...

Based on the insitu tests, Fig. 8 shows the relationship between the shear strength and the normal stress of the test samples. The shear strength parameters of the soil were φ=° and c=173 kPa. After mixing rock blocks, the shear strength parameters of S–RM were φ=° and c=138 kPa.

Lime can stabilize finegrained subgrade or subbase. Subgrade stabilization usually involves in situ mixing of soil and stabilizer, and generally requires 3 to 6 per cent of lime by weight of the dry soil. If quicklime is used as a form of lime in soil stabilization, it chemically reacts with water and releases heat.

2. CDM method mixes soft soil in situ with cement slurry without any jetting. The soil should have mineral soils like sand and clay for hydration product with cement. 3. Because of a series of overlapping augers, it saves soil mixing time and labor while maintaining efficiency in comparison with previous method. 4.

The appropriate vane is chosen for the expected strength of the soil to be tested. The T 174 vane can be used both in situ and in the laboratory for soils having Cu = 24 t/sqm (240 kpa). The T 174 is particularly suitable in soft to medium cohesive soils where other tests do not provide adequate accuracy.
