Soil boring with wash boring process service active standard ASTM D1587, Casing with a diameter about 50 to 100 mm and to a depth of 1.5 m to 3.0 m is directly driven into the soil surface. The casing is full of chopping bit tied on lower end of a wash pipe inner the casing in mandate to take away the soil. At first water is compulsory through the wash pipe that appears adjacent the chopping bit through a small starting with a high speed. Due to the high rapidity of water, the soil is slashed into oddments and soil water gets up through ring area between the wash pipes and casing. the T-connection fixed at the top aids the assemblage of wash water in a pond made handy.
Soil boring a hole, the wash water again compiled is anew pumped through a hose into the wash pipe. As the method continues, a borehole is advanced and further casing pipe and drill rods are extra. A swivel head equipped between the water hose and water pipe so that the wash pipe and chopping bit can be distorted and pressured down whereby the borehole is advanced further into the soil of soil boring. But, while civil engineer drive the casing into the soil, the swivel head is eliminated. Following the same method frequently, a borehole of essential depth is obtained. This type of method of soil boring test is appropriate for all types of soil other than gravels and boulders.
And, to include more this process is very swift. For clayey soil, casing is unnecessary. Observing the slurry streaming out of the hole, civil engineer can predict the type of soil. Likewise, the change of color in the wash water predicts the change in rock strata layers of the soil.
Soil boring and soil samples are taken from the materials settled in the cesspit. But, the soil samples thus taken would be extremely disturbed and equips only a irregular forecast of the soil type. For adequate accuracy of the samples taken, we follow a suitable sampling procedure at any desired depth by replacing the chopping bit with a sampling tube.
For sufficient exactitude of the samples taken, we follow a appropriate sampling method at any imposed depth by substituting the chopping bit with a sampling tube. Mainly, this method is used for the preparatory soil boring moment of the exploration.
Wash boring is soil boring test implement by water injection passing drilling rod through borehole with high pressure water pump and flow to chopping bit for soil impingement or soil mastication. Soil was damaged until size of soil is smaller which soil is moved up at the borehole wall by water and flowed down in portable slush that is side of the borehole for coarse grain Soil precipitation and then some water is pumped for water reuse. This Soil boring test method is necessary for protection damage of borehole wall from casing hammering down into soft clay layer. In case for soil boring is deeper than sand layer which is essential to use bentonite for borehole collapse.
Motorized drilling machine is easy for transposition and installation. You can observe soil layer variation by soil classification such as sand or gravel and color of water overflow from top soil and stickiness or plasticity index of soil layer each soil provoke time that is useful for transfiguration of soil. Soil classification will be difficult, If slush is mixed bentonite.
This is the soil boring test with rotary drilling rig by each setting of speed. It has the hole for the water injection by pumping from water tank and resemble with wash boring but it is action so cold with your hand on drilling rod which is hard for forecast of soil layer changing while rotary drilling rig is operating, you shall be observed differentiation of hydraulic pressure and flow rate of drilling rod. Rotary drilling method by used pressure of water pump is injected soil while operating and you are going to observe following depth level specification and then auger bit is brought up from bore hole and represented with regular auger. It is necessary to keep undisturbed samples full capacity. Soil boring test with rotary rotary drilling rig is good for hard clay, gravel, gravelly sand and decomposed rock because it is easy for auger bit changing follow soil condition. If you discover the hard rock, you are necessary to use diamond bit.

Soil boring to determine the capacity of the soil. Civil engineering tests to determine the capability of the soil to support proposed improvements or to determine the strength and properties of a required building foundation. Expansive clay soil or rock outcroppings may affect the required foundation.
