Detailed explanation-1: -Push probes, hammer probes, and bucket augers (Figure 1) are commonly used because they are capable of taking uniform samples with depth. Figure 1. Examples of soil sampling equipment: a soil push probe, hammer probe, and bucket auger. Along with a probe, a clean plastic bucket should be used.

Detailed explanation-2: -Disturbed samples are usually taken from the bucket of the excavator, or from the side of a shallow pit. Undisturbed samples may be obtained by hand‐cutting blocks of soil in shallow pits, but it is more common to use sample tubes (described in Section B. 2.2) to obtain standard undisturbed samples.

Detailed explanation-3: -The soil samples whose natural structural integrity gets changed, during the process of collection, to a considerable amount is called disturbed soil samples. These changes could be in the soil structure, in the stress condition, in its texture, in the water content and void ratio, in chemical properties, etc.

Detailed explanation-4: -April, 30 2022. Soil is one of the most important natural resources on earth and the foundation in many construction projects like roads, buildings, and other infrastructure. Geotechnical soil sampling is a process used by engineers and soil consultants to assess soil properties.
