 Easy operation Sampling & Standard Penetration Test Equipment for sale  

1. Concept:

The Standard Penetration test (SPT) is a common in situ testing method used to determine the geotechnical engineering properties of subsurface soils. It is a simple and inexpensive test to estimate the relative density of soils and approximate shear strength parameters.

2.SPT equipment includes:

1. auto trip hammer 63.5kg/140lb

2. split barrel

3. soil sampler

4. tugger 

5. dynamic probe

6. hammer lever

3. Features

Easy operation,convenient to use

Can work with drilling rig directly

Applied in clayey soil, sandy soil,wide application

clayey soil, sandy soil

4.Standard Penetration Test Prcess

SPT, involves driving a standard thick-walled sample tube into the ground at the bottom of a borehole by blows from a slide hammer with standard weight and falling distance. The sample tube is driven 150 mm into the ground and then the number of blows needed for the tube to penetrate each 150 mm (6 in) up to a depth of 450 mm (18 in) is recorded. The sum of the number of blows required for the second and third 6 in. of penetration is reported as SPT blowcount value, commonly termed  "standard penetration resistance" or the "N-value".
