TOPIC : HOW TO SOIL SAMPLING (HAND AUGER)

INTRODUCTIONSoil samples are often categorized as being either disturbed or undisturbed. Hand augers are commonly used for obtaining disturbed soil samples at or near the surface and for boring to depths where samples may be obtained with a soil sampler or soil core sampler. The augers are rotated into the ground until they are filled, and then lifted out of the borehole to be emptied. A different auger can be used for each formation (soil)type. The hand auger may be used till the depth of about 6 meters ( or more if required).

THE STEPS(PROCUDERS).First, the handauger andT-handling was fixup correctly.

Seconds, the hand auger waspress down intothe ground androtated the handle clockwise until the hand auger sink to the ground at the specified area.

Thirdly, when the hand auger sink intothe ground, the handle was pullout slowly to takeout the sample of soil from the hand auger.

4) Then, the hand auger waspush down back into thedredge hole, and continue turning the handling and obtain the sample of the soil at another depth.

5) After that, do the same stepuntil you have fourdifferent samples from thesame hole at different depth.

6) Finally, the soil stratas thickness and get the value of water contents of soil was determine.DOS AND DONTS DOSDONTSDOconsider patterns of behavior or similar situations that have occurred in yourorganization when determining appropriate remediation.Do not do any experiments without your teachers permission2) DOtreat all parties with respect. Studies show that employees who feel they are treatedunfairly during their employment are five times more likely to file a claim.2) DONTrush. Create a plan for your investigation by identifying what issue(s) you are tryingto resolve, what documents to review and who to interview.

3) Keep the site and laboratory clean and tidy.3) DONTmake assumptions. As an investigator, you must remain impartial and avoidrushing to judgment. If you dont think you can do this, find someone who can.

CONCLUSIONFrom the activity in this laboratory work, we have learnt and applied two methods of soil sampling known as disturbed and undisturbed. The undisturbed soil sample was obtained using a sampling tube and has little effect on the properties of the soil. From this sample, we have determined the moisture content of soil. From visual examination , the type of soil assumed is sandy clay with some mineral content due to the sand particles present in the soil after drying. The mineral content orpeat is seen in the soil represented by some black soft patches. However, visual examination is indefinite and unreliable
