Soil samples inside the tubes can be readily evaluated for disturbance or other features such as presence x1587 fissures, inclusions, layering or voids using X-ray radiography D if facilities are available.
Active Risk Management
For information on preservation and transportation process of soil samples, consult Practice D Land Use and Development. There were no books found for the applied search filters. Unconfined compression tests should be only used with caution or based on experience because they often provide unreliable measure of undrained strength, especially in fissured asm. Sistemas y componentes mecanicos de uso general Proper lengths to be determined as suited to field conditions.
Extruded cores can be preserved by encasing the cores in plastic wrap, tin foil, and then microcrystalline wax to preserve moisture. Use of metric equivalent is acceptable d15877 long as thickness and proportions are similar to those required in this standard. However, the piston samplers are designed to recover soft soils and low-plasticity soils and the thin-walled tubes used must be of lower C r of 0.
Subsurface geotechnical explorations should be reported in accordance with practice D For more information on preservation and transportation process of soil samples, consult Practice D Thin-walled tubes used in piston, plug, or rotary-type samplers should comply with Section 6.
While the sample and push lengths are shorter than the tube, see 7.
The absence of slough, cuttings, or remolded soil in the top of the samples should be confirmed to ensure stable conditions 7. Medio ambiente y proteccion de la salud. For more information on preservation and transportation process of soil samples, consult Practice D Are you sure you want to empty the cart? 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.
Note 2 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. No items in cart.

Tecnologia del cuidado de la salud For information on appropriate use of other soil samplers refer to D The push equipment should provide a smooth continuous vertical push.
This tube can provide intact samples for most laboratory tests; however some tests may require larger diameter tubes. Disturbance and sample quality can be evaluated by astmm at recompression strains in the One-Dimensional Consolidation test see Andressen and Kolstad 5. Reliable results f1587 on many factors; Practice D provides a means of evaluating some of those factors. This sampling method is not recommended for sampling soils containing coarse sand, gravel, or larger size soil particles, cemented, or very hard soils.
It is the responsibility of the user of this standard to establish appropriate safety and health asrm and determine the applicability of regulatory limitations prior to use. Subsurface geotechnical explorations should be reported in accordance with Practice D Tubes of thicker gauge may be requested when re-use is anticipated see 6.
Gravelly soils cannot be sampled and gravel will damage the thin-walled tubes. Active view current version of standard. This practice discusses some aspects of sample preservation after the sampling event.
