ASTM D – 00 Standard Practice for Thin-Walled Tube Sampling of Soils for Geotechnical Purposes

Active view current version of standard. While the sample and push lengths are shorter than the tube, see 7. The tubing tolerances presented in are from sources available in North America. Other soil samplers may be used for sampling these soil types. The double-tube samplers are thicker walled and require special considerations for an outside cutting shoe and not the inner thin-walled liner tube.

Such samplers include driven split barrel samplers and soil coring devices Test Methods DDand Practice D You must be logged in to sign up for monitoring You must be logged in to sign up for subscription. This axtm cannot replace education or experience and should be used in conjunction with professional judgment.

Sands are much more difficult to penetrate and may require use of smaller diameter tubes. Users of this practice are cautioned that compliance with Practice D does not in itself ensure reliable results.

Soil samples inside the tubes can be readily evaluated for disturbance or other features such as presence of fissures, inclusions, layering or voids using X-ray radiography D if facilities are available.

Subsurface geotechnical explorations should be reported in accordance with practice D See Appendix X1 for recommended techniques. Unconsolidated undrained tests are more reliable but can still suffer from disturbance problems. This practice provides guidance on proper sampling equipment, procedures, and sample quality evaluation that are used to obtain intact samples suitable for laboratory testing.

Agencies that meet the criteria of Practice D are generally considered capable astn competent and objective sampling. Low-plasticity silts can be sampled but in some cases below the water table they may not be held in the tube and a piston sampler may be required to recover these soils.

For information on appropriate use of other soil samplers refer to Practice D Disturbance and sample quality can be evaluated by looking at recompression strains in the One-Dimensional Consolidation test see Andressen and Kolstad 5. Figure 2 shows the standard sampler with a ball check valve in the head, which is used in fluid rotary drilled holes. Activation of your subscription failed – please try again later or contact us.

The quality of the result produced by this standard is dependent on the competence of the personnel performing it, and the suitability of the equipment and facilities used. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

Lengths of tubes shown are illustrative. Consolidation test specimens are generally larger diameter than those for strength testing and larger diameter soil cores may be required. Longer time periods may be allowed depending on logistics and the quality assurance requirements of the exploration plan.

Thin-walled tubes used in piston, plug, or rotary-type samplers should comply with Section 6.

This practice discusses some aspects of sample preservation after the sampling event. Proper lengths to be determined as suited to field conditions. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Du abonnerer allerede dette emne.

The SI values given in parentheses are provided for information purposes only. Such samplers include driven split barrel samplers and soil coring devices Test Methods D, D, and Practice D Historical Version s – view previous versions of standard.

Aztm tubes are also usually supplied with a machine-beveled inside cutting edge which provides the Clearance Ratio C r.

The most commonly used tube is the 3-in. Other soil samplers may be used for sampling these soil types. One variation is a R1587 thin-walled sampler that is capable of holding a vacuum on the sampler to improve recovery 12. These samplers use high C r tubes of 1. If samples are taken in uncased boreholes the cores should be inspected for any sidewall contamination.

A piston sampler Practice D must be used to ensure that there is no fluid or sidewall contamination that would enter an open sampling tube. The printed version is available at half price when you buy the electronic version. For information on appropriate use of other soil samplers refer to D Subsurface geotechnical explorations should be reported in accordance with Practice D This sampling method is not recommended for sampling soils containing coarse sand, gravel, or larger size soil particles, cemented, or very hard soils.

The absence of slough, cuttings, or remolded soil in the top of the samples should be confirmed to ensure stable conditions 7.
