Geophysical exploration, if required. t. Conducting all the necessary tests on the samples of soil/rock and water collected. Preparation of drawings, charts, etc. -. Analysis of the data collected. Preparation of report. 3.2 BORNG OF HOLES. Auger Method. Hand operated augers. Auger boring is the simplest of the methods.
The purpose of a soil investigation program. 3. 1. Selection of Establishment of construction methods for changing subsoil conditions. Page 4. Exploration Program. 4. The purpose of the exploration program is to determine, within practical limits, the stratification and engineering properties of the soils underlying the site.
Introduction. • Methods of investigation. • Methods of boring. • Soil samplers and sampling. • Location and number of pits and borings. • Penetration tests. • Borehole logs. • Geophysical methods
The several exploration methods for sample recovery*. Disturbed samples taken. Method. Depths. Applicability. Auger boringt. Depends on equipment and time. All soils. Some difficulty may be available, practical depths being encountered in gravelly soils. Rock up to about 35 m requires special bits, and wash boring is.
3 Sep 2010 Soil investigation and soil explorations are conducted for the purpose of site investigation to get clear information about the soil properties and hydrological conditions at the site. Site Reconnaissance Site reconnaissance is the inspection of the site and study of topography to get a proper information about
