Use deep soil-cement mixing equipment with a single shaft or multiple shafts with multiple augers configured in one straight line. Uniformly inject cement grout through the bottom of the assembly. Advance mixing equipment through in-situ
To perform the vane shear test, a vane is pushed di-rectly into a soil layer and rotated until the soil fails. The torque required to fail the soil along the vertical and horizontal edges of the vane is a relatively direct measure-ment of the shear strength. On this study the field vane shear tests were performed using the Geonor vane equipment
Take the soil specimen in container which is generally 75 mm in height and 37.5 mm in diameter. Level the soil surface on the top and mount the container on the base of vane shear test apparatus using screws provided. Lower the vane gradually into the soil specimen until the top of vane is at a depth of 10 to 20 mm below the top of soil specimen
5. Dry soil mixing:A ground treatment system used to improve the engineering properties of soft clays, peats and other weak soils, by mechanically mixing them with dry cementitious binder to create a soil-cement mix. 6. Mixing Tool: Equipment used to disaggregate the soil and distribute and mix the binder with the soil

The efficiency of the DSM equipment and ground treatment construction time may be factors in determining the quantity of binder required. Within each Test Area, the Contractor must propose three trial mixes to determine the production mixing parameters

Deep Soil Mixing (DMM, CDM, CDSM, DSM) • Deep Soil Mixing (DSM) is an in situ soil treatment technology whereby native soils are blended in situ with cementitious materials, typically Portland cement. • Geotechnical -The soil-cement mixture created by DSM has increased strength, lower permeability and reduced compressibility
This vane shear test kit is an instrument dedicated to measuring the natural shear strength of saturated soft clay on site
Standards:IS 4434-1967. Specification: The apparatus is designed for conducting in situ vane shear test from bottom of a bore hole in saturated cohesive deposits for determining their in place shearing resistance. The equipment consists of a torque applicator assembly mounted on a base, a gear wheel, which is marked in degrees, holds a torque ring and is geared to a crank, the

They all include a peak hold. ... This apparatus is designed for conducting in-situ Vane Shear test
advanced into the soil, grout is pumped through hollow drill shaft and injected into the soil at the pilot bit. The cutting edges and mixing blades blend the soil and grout with a shearing motion. When the design depth is reached the auger head is raised to expose the mixing blades at the surface and then allowed to readvance to the bottom
The Vane Shear Set provides a rapid check of the stability of foundations, excavations and trenches in clay. The total range is 0 to 260kPa (0 to 2.6 ton/sq. ft.). The scale built into the handle holds the peak value until reset. Accuracy is 10%
DEEP SOIL MIXING is a soil improvement technique used to construct cutoff or retaining walls and treat soils in-situ. This is accomplished with a series of overlapping stabilized soil columns (typically 36-inch diameter). The stabilized soil columns are formed by a series of mixing shafts (2 to 4) guided by a crane supported set of leads. As
The design is very similar to the well known 'Geonor' shear vane. It consists of a cylindrical body containing a torsional spring and three interchangeable vanes of different sizes. The appropriate vane is chosen for the expected strength of the soil to be tested. It can be used both in situ and in the laboratory for soils having Cu = 24 t/sqm (240 kpa)

POWER & DURABILITY TO MIX SOIL Soil Mixers are able to effectively mix a variety of materials including: clay, silt, peat, sludge, sediment, dredged material, and contaminated soil
mixing tool. The mixing drums penetrate and mix a variety of material in place or insitu. Materials can be mixed anywhere the excavator can go, capitalizing on the excavator's mobility and articulation to reach difficult or soft areas. Binders or chemical agents are delivered to the area of the highest mixing shear

SOIL. Soil is one of the oldest forming structures that our planet is formed from. Soil is a loose rocky material that is vastly used in the construction industry. Hence, it is very important to test the ground soil before construction and to know the type and classification of the soil before any project. The type of soil can be identified by
