1、Designation: D5782 18Standard Guide forUse of Direct Air-Rotary Drilling for GeoenvironmentalExploration and the Installation of Subsurface Water-QualityMonitoring Devices1This standard is issued under the fixed designation D5782; the number immediately following the designation indicates the year o
2、foriginal adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope*1.1 This guide covers how direct (straight) air-rotary drill-
3、ing procedures may be used for geoenvironmental explorationand installation of subsurface water-quality monitoring de-vices.NOTE 1The term direct with respect to the air-rotary drilling methodof this guide indicates that compressed air is injected through a drill-rodcolumn to a rotating bit. The air
4、 cools the bit and transports cuttings to thesurface in the annulus between the drill-rod column and the borehole wall.NOTE 2This guide does not include considerations for geotechnicalsite characterizations that are addressed in a separate guide.1.2 Direct air-rotary drilling for geoenvironmental ex
5、plora-tion will often involve safety planning, administration, anddocumentation. This guide does not purport to specificallyaddress exploration and site safety.1.3 The values stated in SI units are to be regarded asstandard. The values given in parentheses are for informationonly.1.4 This standard d
6、oes not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety, health, and environmental practices and deter-mine the applicability of regulatory limitations prior to use.1.5 All observed a
7、nd calculated values are to conform to theguidelines for significant digits and rounding established inPractice D6026. The procedures used to specify how data arecollected/recorded or calculated in this standard are regarded asthe industry standard. In addition, they are representative of thesignifi
8、cant digits that generally should be retained. The proce-dures used do not consider material variation, purpose forobtaining the data, special purpose studies, or any consider-ations for the users objective; and it is common practice toincrease or reduce the significant digits of reported data to be
9、commensurate with these considerations. It is beyond the scopeof this standard to consider significant digits used in analysismethod or engineering design.1.6 This guide offers an organized collection of informationor a series of options and does not recommend a specificcourse of action. This docume
10、nt cannot replace education orexperience and should be used in conjunction with professionaljudgment. Not all aspects of this guide may be applicable in allcircumstances. This ASTM standard is not intended to repre-sent or replace the standard of care by which the adequacy ofa given professional ser
11、vice must be judged, nor should thisdocument be applied without consideration of a projects manyunique aspects. The word “Standard” in the title of thisdocument means only that the document has been approvedthrough the ASTM consensus process.1.7 This international standard was developed in accor-dan

20、Data3. Terminology3.1 DefinitionsFor definitions of common technical termsused in this standard, refer to Terminology D653.3.2 Definitions of Terms Specific to This Standard:3.2.1 bentonite, nin drilling, the common name for drill-ing fluid additives and well-construction products consistingmostly o
21、f naturally occurring montmorillonite. Some bentoniteproducts have chemical additives which may affect water-quality analyses.3.2.2 cleanout depth, nin drilling, the depth to which theend of the drill string (bit or core barrel cutting end) hasreached after an interval of cutting. The cleanout depth
22、 (ordrilled depth as it is referred to after cleaning out of anysloughed material in the bottom of the borehole) is usuallyrecorded to the nearest 0.1 ft (0.03 m).3.2.3 drawworks, nin drilling, a power-driven winch, orseveral winches, usually equipped with a clutch and brakesystem(s) for hoisting or
23、 lowering a drilling string.3.2.4 drill hole, nin drilling, a cylindrical hole advancedinto the subsurface by mechanical means. Also known as aborehole or boring.3.2.5 drill string, nin drilling, the total rotary-drillingassembly under rotation including bit, sampler/core barrel, drillrods, and conn
24、ector assemblies (subs). The total length of thisassembly is used to determine drilling depth by referencing theposition of the top of the string to a datum near the groundsurface.3.2.6 air rotary drill string, nin drilling, the total directair-rotary drilling assembly under rotation including bit,s
