How to perform Bitumen Penetration Test - Procedure, Method, Significance & Uses
Standard Penetration Test (SPT) of Soil – Procedure, Tools, Precautions.
Further, it should be ensured that the three legs of the tripod are firmly supported on the ground i. In certain circumstances, it can be useful to continue driving the sampler beyond the distance specified, adding further drilling rods as necessary. The soil can be reconstituted for some advanced laboratory tests. Please enter your comment!
You know, lots of people are looking round for this information, you could help them greatly. The blow count provides an indication of the density of the ground, and it is used in many empirical geotechnical engineering formulae. Therefore, the closest spacing for typical practice of SPT is 2. As the standard does not provide any technical guidelines as far as how to execute an actual pentest, we have also created a technical guide to accompany the standard itself. Personal tools Log in.
The great merit of the test, and the main reason for its widespread use is that it is simple and inexpensive. This is driven into the ground at the bottom of a borehole by blows from a slide hammer with a mass of The test is extremely useful for determining the relative density and the angle of shearing resistance of cohesionless soils. From Wikipedia, the free encyclopedia. By pulling the rope down, the drive weight, guide pipe assembly, A-drill rod and the split spoon sampler will get vertically erected. Thus, since the SPT itself requires 1.
