Methods of Soil Investigation and Soil Exploration and,

Drilling a hole and visually examining the cuttings coming out from different depths; Lifting the soil samples from different depths by using mechanical devices called samplers. Methods of boring. 1. Auger boring. This is simplest method of boring a hole by hand drilling.Geotechnical investigation - Wikipedia,Small-diameter borings are frequently used to allow a geologist or engineer to examine soil or rock cuttings or to retrieve samples at depth using soil samplers, and to perform in-place soil tests. Soil samples are often categorized as being either "disturbed" or "undisturbed;" however, "undisturbed" samples are not truly undisturbed.NOTES on the STANDARD PENETRATION TEST,Origins of the Standard Penetration Test Around 1902 Colonel Charles R. Gow, owner of the Gow Construction Co. in Boston, began making exploratory borings using 1
