| Глоссарий по проходческим щитам (тоннелингу) |
The loss of drilling fluid, including slurry and lubrication, from the slurry or lubrication system. a special form of inadvertent return, where the fluid exceeds the strength and confining pressure of the ground and reaches the surface or waterway, is called a hydrofracture or frac-out.

Return cargo, английский
- A cargo which enables a ship to return loaded to the port or area where her previous cargo was loaded.
- Обратный груз
Return cause, английский
Lubrication, английский
- The control of friction and wear by the introduction of a friction-reducing film between moving surfaces in contact. the lubricant used can be a fluid, solid, or plastic substance.
- Смазка
- On no account should oil be used to lubricate pin-tumbler cylinders. graphite is the conventional lubricant for this mechanism.
- Смазка (действие)
- The act of injecting a fluid, normally bentonite and/or polymers, to reduce the skin friction and jacking forces on the jacking pipe during installation. the fluid fills the annular space.
- Means of reducing friction either around a pipe being jacked or a shaft being sunk into the ground.
- The control of friction and wear between two moving, touching surfaces by placing a friction-reducing substance between them.
- Control of friction and wear by the introduction of a friction reducing film between moving surfaces in contact. the film may be fluid, solid or plastic.
- Reduction of friction or wear between two load-bearing surfaces by the application of a lubricant; includes boundary lubrication (thin or interrupted fluid film, especially bearings where wear occurs); mixed film, where some liquid pools support the load; elastohydrodynamic (high-pressure loads increase the lubricant’s viscosity and load-carrying capacity, especially in gears); hydrodynamic (a thick fluid film lubrication, especially in journal bearings) and hydrostatic (external pump pressure used to form a thick fluid film, as in start-up of journal bearings).
Hydrofracture, английский
- A special form of inadvertent return in which drilling fluid reaches the surface or waterway. also called a frac-out.
- The inadvertent loss of drilling fluid from the borehole annulus to the surrounding soil as a result of excess downhole fluid pressure.

N-value, английский
The number of blows per foot required to drive a standard penetration test (spt) soil sampler into the ground during geotechnical exploration. the n-value is often used to estimate in situ consistency of clays and silts and relative density of sands.
Maximum allowable jacking force, английский
The largest jacking force that can be applied to the jacked pipe, allowing for an appropriate factor of safety.
