ISO Automatic Trip Hammer For Standard Penetration Test Soil Sampling

Soil Sampling Equipment, Automatic Trip Hammer for Standard Penetration Test Soil Sampling

Soil Sampling Equipment
 

Soil sampling equipment for obtaining soil samples at or near the surface in environmental sampling and monitoring and geotechnical testing applications.
 

Our samplers range in length from 18" to 24", the "Lynac" sampler head has coarse threads which make assembly/disassembly much faster and all shoes for samplers are heat treated to withstand continued heavy use.
 

A ball check feature prevents a washout of material when retrieving a finished sampler. Split-spoon samplers are used in geotechnical analysis which don’t require undisturbed samples, and chemical analysis. Liners are used with split spoon samplers which allow for collection of samples suitable for chemical analysis of many types of contaminants. Split spoon samplers consist of a barrel attached to a drive tip; obtain samples by attaching the split spoon to the end of a drill string, lowering it to the bottom of a borehole, and then driving it into the soil with a geotechnical hammer.

Complete Sampler Assemblies:

. Standard: 1-1/2” – 4”
. Lynac Standard & Heavy Duty: 2” – 4”
. Stainless: 2” – 3”
. California Modified: 2” – 4”

The Standard Penetration Test (SPT) and Cone Penetrometer Test (CPT) have become industry standards for subsurface geotechnical investigations using small diameter (<8-in. [20-cm]) borings and soundings. Both procedures have evolved over a period of 100 and 70 years, respectively, and have been adopted as ASTM standards. Each procedure has certain advantages over the other, but both can elicit incorrect data under particular subsurface conditions that are often overlooked, depending on the experience of field personnel operating or logging the tests. This paper seeks to explain the operative assumptions employed in both procedures, highlight the various corrections that are commonly employed, and warn the reader of common errors in interpretation.
The article concludes by stating that, under most conditions, the joint employment of SPT and CPT together has the greatest potential for characterizing sites correctly.
