Jacking of Long Pipe Section Beneath a Highway
An awareness of the critical factors and proper design aided a contracting company to pass a 1/2‐inch thick, 66‐inch diameter steel shell beneath a six‐lane highway in Queens, New York. The job was done without mishap or settlement of the road above. The 102‐ft pipe was held to a 1‐in. line and grade tolerance without difficulty, and cleared a 48‐in. overhead sewer by 8 in. at the receiving end. Although the contractors were prepared to sink a shaft at midpoint and jack from both ends, this was not necessary. Sufficient jacking force was made available to push the pipe through without excessive deviation; the pipe was made heavy enough to withstand buckling. The steel pipe acted as a cylinder through which a 48‐in. concrete water line passed. The space between pipes was later grouted.
