Horizontal directional drilling (hdd)
| Глоссарий по проходческим щитам (тоннелингу) |
- A surface-launched trenchless technology for the installation of pipes, conduits, and cables. hdd creates a pilot bore along the design pathway and reams the pilot bore in one or more passes to a diameter suitable for the product, which is pulled into the prepared bore in the final step of the process.
- Method for the installation of pipes, conduits and cables using a surface-launched drilling rig. a pilot bore is drilled using a rotating drill string and is then enlarged by a back reamer to the size required for the product pipe. during the pilot bore the direction of the drill string is controlled by the orientation of a slanted face to the drill head, eccentric fluid jets or a combination of these, usually in conjunction with a locator.

Technology, английский
- The use of tools and knowledge to meet human needs.
- Техника; технология
- Техника (означает все знания или неотъемлемую часть знаний о: научных принципах или открытиях; промышленных процессах; материальных и энергетических ресурсах; средствах транспорта и связи, постольку, поскольку эти знания непосредственно касаются развития производства товаров или сферы услуг; документы юнеско)
- N технология speech recognition ~ технология распознава- ния речи3
- Национальный институт стандартов и технологии
- Технология
- The body of knowledge about, and the systematic study of, methods, techniques and hardware applied in the adaptation of the physical environment to man`s needs and wants. the application of scientific knowledge to build or improve the infrastructure of agriculture, industry government and daily life. (technology must not be confused with the very infrastructure it generates). technology has autocatalytic properties. it favores the use of technical devices and processes even in solving social problems, e.g., by using fertilizers to enhance agricultural production rather than a different form of work organization, by using computers for national planning rather than decentralized decision making processes.
- The practical application of knowledge to achieve particular tasks that employs both technical artefacts (hardware, equipment) and (social) information (‘software’, know-how for production and use of artefacts). supply push aims at developing specifi c technologies through support for research, development and demonstration. demand pull is the practice of creating market and other incentives to induce the introduction of particular sets of technologies (e.g., low-carbon technologies through carbon pricing) or single technologies (e.g., through technology-specifi c feed-in tariffs).

- As used in borehole surveying and directional drilling practice, "orientation" refers to the method and procedure used in placing an instrument or tool, such as a deflection wedge, in a drilled hole so that its directional position, bearing, or azimuth is known.
- Placement with respect to the cardinal directions, n, s, e, w; azimuth is the measure of orientation from north.
- In linear polymeric structures, the degree of parallelism of the chain molecules.
- The alignment of an item, such as a control.
- The direction a publication will be printed on a sheet of paper. you can choose either portrait, which is the taller-than-wide orientation, or landscape, which is the wider-than-tall orientation.
- Position of a discontinuity or part or surface in relation to the test surface of the article or ultrasonic beam.

Pipe ramming, английский
- A trenchless installation method whereby a percussive hammer is attached, via an adapter, to an open-end casing, which is then driven through the ground. to create an open casing, the spoils within the casing are removed after the drive is completed, or periodically during the drive.
- Non-steerable method of forming a bore by driving a steel casing, usually open-ended, with a percussive hammer from a drive pit. the soil may be removed by augering, jetting or compressed air. in appropriate ground conditions a closed casing may be used.
