Definition - What does Rod Pushing mean?
Rod pushing is the trenchless method of driving a closed end pipe through the earth in order to form a pilot bore. The material is simply displaced, or the head is left open and the soil is collected inside the pipe. This process suffers from a lack of accuracy due to limited or no steering or monitoring capabilities.
This method is also known as thrust boring.
Trenchlesspedia explains Rod Pushing
Rod pushing is not usually recommended 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, rod pushing is inexpensive and can usually needs a short installation time. It is best suited for lengths less than 60 feet.
