The construction method of using excavators to advance pipelines primarily relies on directional drilling technology. This technique, which uses pre-drilled pilot holes to pull the pipeline back underground, is highly efficient and precise.
A directional drill drill drills the pilot hole according to the designed trajectory, and the drill bit's position is adjusted in real time via a wireless directional control system.
A reaming drill bit is attached to the end of the drill pipe to enlarge the hole diameter, and the pullback force then pushes the pipeline underground. In soft formations, pipe jacking can be combined to assist in traversing obstacles.
Directional drilling shortens construction time and is not restricted by season, making it particularly suitable for laying pipelines for power, gas, and telecommunications. It eliminates the need for excavation and is suitable for laying pipelines for power, gas, and telecommunications.
It reduces surface damage, noise, and dust pollution during construction. This technology is highly adaptable to ground conditions, but still presents challenges when crossing hard rock formations or large-diameter pipes over long distances.
