Definition - What does Thrust mean?
Thrust is a reactive force that propels an object in a linear fashion. In the context of trenchless technology, it is the force applied to a pipe or casing, through jacking or other means, to push it further into the ground. Thrust is an important concept in the formal science of physics, and in trenchless construction. It can be calculated using well-established mathematical methods.
Trenchlesspedia explains Thrust
Thrust is related to the Newton’s third law of motion. The opposite reaction involved in thrust is directly proportional to the amount of force acted upon it. Understanding thrust is essential to directional drilling and pipe jacking. Trenchless construction workers need to know precisely how much force is required to advance pipe or casing through the ground or to move forward with a drill. It is essentially a force directed in a straight line. A related term is torque, which is a twisting force. Thrust and torque are the forces used in drilling.
