This document discusses different methods of boring including auger, auger and shell, wash, percussion, and rotary boring. It provides details on each method such as the types of soil they are used in, how they operate both manually and mechanically, and their applications. The main methods discussed are auger boring which is used in sandy and soft soils, wash boring which uses water jets to disintegrate soil, and rotary boring which uses diamond or shot bits to take undistributed soil samples from hard and rocky areas. In conclusion, boring methods are used for soil testing, studying soil strata, and obtaining information about fossils, minerals, and other subsurface materials.

- 1. BORING
- 2. PRESENTATION ON BORING By :- Mital Damani
- 4. INTRODUCTION PITS – small/large hole on land. BORING is one type of Pit. Y??????
- 6. AUGER BORING Mostly used in Sandy soil, soft soil, clayey soil. It can operated Manually (6m) as well as Mechanically (15m). Mostly is Driven Vertically .
- 8. AUGER & SHELL BORING Mostly used in Soft Clay. This AUGER Is different from other auger : Cylindrical in shape having diameter of 75 to 200mm,hollow tube with cutting edge at bottom. Operated Manually (25m) as well as Mechanically(50m).
- 9. PHOTOS OF AUGER AND SHELL
- 10. WASH BORING Mostly it is used in Soft Stiff Cohesive & Sandy Soils. The operation caring out : By using Casing Pipe ,through which a hollow drilled rod with a sharp chisel Or Chopping bit is inserted at lower end . The main role play in this is WATER.
- 11. WASH BORINGS
- 12. WASH BORING
- 13. WASH BORING.. The Chopping & jetting action of the bit & water disintegrate the soil. Also cutting action is used . From this method SOIL STRATIFICATION is judged.
- 14. PERCUSSION BORING Mostly used in Rocky area & soil having Boulders. This is only method in which material state is converted other that is from PULVERISED TO SLURRY.
- 17. ROTARY BORING Mostly used in Hard & coursed as well as in Rocky area. This only method of boring in which UNDISTRIBUTED Sample is taken out. Operation carried out : Hollow steel tube is used for SUCKING out the MATERIAL. Cutting bits makes annual cut in strata & leaves a cylindrical core of the material in the hollow tube.

- 22. TYPES OF ROTARY BORING Diamond -> INDUSTRIAL DIAMOND Shot -> CHILLED STEEL
- 23. APPLICATION Land excavation Water For extract out PETROLIUM PRODUCT Testing of soil sample For checking soil capacity.
- 24. CONCLUSION We are use for testing of soil sampling To study soil strata For getting info.of fossil ,mineral,etc…
