Active Risk Management
The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Other soil samplers may be used for sampling these soil types.
This document cannot replace education or experience and should be used in conjunction with professional judgment.
Subsurface geotechnical explorations should be reported in accordance with Practice D Active view current version of standard. The sample depth of the sampler should coincide with the drilled depth.
Disturbance and sample quality can be evaluated by looking at recompression strains in the One-Dimensional Consolidation test see Andressen and Kolstad 5. This sampling method is not recommended for sampling soils containing gravel or larger size soil particles cemented or very hard soils.

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.
This sampling method is not recommended for sampling soils containing coarse sand, gravel, or larger size soil particles, cemented, or very hard soils. This sampling method is not recommended for sampling soils containing coarse sand, gravel, or larger size soil particles, cemented, or very hard soils.
Such samplers include driven split f1587 samplers and soil coring devices Test Methods D, D, and Practice D 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. This is because once the core is in contact with the steel tube, there are galvanic reactions between the tube and the soil which generally cause the annulus core to harden d11587 time.
The recommended combinations of A rcutting angle, and C r are given below also see 6. The push equipment should provide a smooth continuous vertical push. Du abonnerer allerede dette emne.
d1857 These samplers use high C r tubes of 1. Link to Active This link will always route to the current Active version of the standard. The piston sampler Practice D uses a thin-walled tube. Wall thickness may be changed 5. They are most often used in fluid rotary drill holes Guide D and holes using hollow-stem augers Practice D Tubes with a diameter of 2 in. Thin-walled tubes used in piston, plug, or rotary-type samplers should comply with Section 6.
The printed version is available asstm half price when you buy the electronic version. Advanced tests, such asrm consolidated, undrained triaxial compression Test Method D testing, coupled with one dimensional consolidation tests Test Methods D and D are performed for better understanding the relationship between stress history and the strength and compression characteristics of the soil as d15587 by Ladd and Degroot, 4.
The one to two week period is just guideline typically used in practice. Longer time periods may be allowed depending on logistics and the astk assurance requirements of the exploration plan. It is not possible to buy in the shop – please contact us. The double-tube samplers are thicker walled and require special considerations for an outside cutting shoe and not the inner thin-walled liner tube.
Proper lengths to be determined as suited to field conditions. Continue shopping Proceed to checkout. For more information on preservation and transportation process of soil samples, consult Practice D Soft clays require C r of 0 or less than 0.
The quality of the d15877 produced by this standard is dependent on the competence of the personnel performing it, and the suitability of the equipment and facilities used. Extruded cores can be preserved by encasing the cores in plastic wrap, tin foil, and then microcrystalline wax to preserve moisture. Please choose number of devices you want to open the document on.
ASTM D – 00 Standard Practice for Thin-Walled Tube Sampling of Soils for Geotechnical Purposes
This practice does not address environmental sampling; consult D and D for information on sampling for environmental investigations. The outside cutting edge of the end of the tube is machined-sharpened to a cutting angle Fig. Sands are much more difficult to penetrate and may require use of smaller diameter tubes. The word “Standard” in the title of this document means only that the document has been approved through the ASTM consensus process. For information on appropriate use of other soil samplers refer to Practice D 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.
Such samplers include driven split barrel samplers and soil coring devices Test Methods DDand Practice D This practice provides guidance on proper sampling equipment, procedures, and sample quality evaluation that are used to obtain intact samples suitable for laboratory testing.
Do not show this again. This practice discusses some aspects of sample preservation after the sampling event. Are you sure you want to unsubscribe? Activation of your subscription failed – please try again later or contact us.
