Pipeline River Crossing Methods: HDD, Microtunneling, Direct Pipe® & Pipe Jacking
There are four main trenchless methods for pipeline river crossings: HDD (fastest for crossings under 5,000 ft), microtunneling (best for grade-critical and hard ground), pipe jacking (for large diameters with crew access), and Direct Pipe® (one-step bore and install with TBM + pipe feeder simultaneously). The right method depends on pipe diameter, crossing length, and ground conditions. The UNI-PF250 pipe feeder supports all four.
