Thrust Boring

Definition - What does Thrust Boring mean?

Thrust boring is the trenchless method of driving a closed end pipe through the earth in order to form a pilot bore. The material is simply pushed out of the way or the head is left open and the soil is collected inside the pipe. Some small diameter models have steering capability achieved by a slanted pilot-head face and electronic monitoring.

This method is also known as rod pushing.

Trenchlesspedia explains Thrust Boring

Thrust boring is not favored because of the likelihood of obstructions and ground heaving as the soil is displaced around the driving rod. If enough space is available, the entire length of the pipe can be welded, installed and driven in one piece. In other cases, the method of welding sections of pipes on site is employed. In general, thrust boring enables an inexpensive and relatively quick installation. It is best suited for lengths less than 60 feet.
