【 摘 要 】

Modern approaches to construction of utility lines are reviewed. The hole-making technology of pipe driving can be improved by introduction of concurrent removal of soil plug by batches, which essentially enhances performance efficiency. The minimum air pressure required to separate batches from soil plug and to move it along a pipe is determined. The feasibility of cyclic destruction and removal of soil plug during pipe ramming is experimentally proved.
