In Soil Boring with wash boring method, a piece of 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 ground. The casing is provided with a chopping bit fastened on the lower end of a wash pipe that is inserted inside the casing in order to remove the soil inside the casing. At first water is forced through the wash pipe which emerges along the chopping bit through a small opening with a high velocity. Due to the high velocity of water, the soil is cut into fragments and soil water slurry comes up through the annular space between the wash pipes and casing. As shown in figure 1, the T-connection fixed at the top aids the collection of wash water in a sump made nearby. During boring a hole, the wash water thus collected is again pumped through a hose into the wash pipe. As the process continues, a borehole is developed and additional casing pipe and drill rods are added. A swivel head provided between the water hose and water pipe so that the wash pipe and chopping bit can be twisted and pressed down whereby the borehole is advanced further into the soil. But, while we drive the casing into the soil, the swivel head is removed. Following the same process repeatedly, a borehole of required depth is obtained.
