Definition - What does Cradle Bore mean?
A cradle bore is a hole created using the cradle boring method of trenchless construction. The advantage of the cradle boring method is that it can begin without the need to build a pit for construction workers. The cradle boring machine is suspended above a starter trench which saves time and effort over conventional boring methods.
Trenchlesspedia explains Cradle Bore
There are a variety of boring methods in the trenchless construction business. Cradle boring is an old method that is finding new life. With the resurgence of pipeline construction in the past few years, contractors have considered bringing older cradle boring equipment back into production. But the older units generally lack the safety features required for today’s construction environment. The choice then, is to retrofit older equipment or manufacture new equipment.
A cradle is used to provide safety to workers. The technician operating the cradle boring machine works securely from a protective space. Safety bars surround the worker and the fact that he is suspended above the ground while operating the machine offers added security. Since no opening pit is required, a cradle bore operator could potentially complete multiple cradle bores in a day.
