Hammer Boring! by EBI Drilling Services at www.ebidrillingservicesmn.com
What is Hammer Boring by EBI Drilling Services?
Hammer Boring is a casing advancement system that uses a down the hole (DTH) air hammer system to pull a casing through the ground. This type of underground drilling system is far superior to Horizontal Directional Drilling (HDD) and Jack and Bore Systems when the ground conditions become unfavorable (Rocky, Cobbles, Bedrock, Mixture of everything, etc.)
Why would you use this style system over typical Horizontal Directional Drilling (HDD) or Jack and Bore System?
When rocky conditions or cobble conditions arise in the bore path, typical HDD rigs have a hard time steering during the creation of the initial pilot hole, rocks get stuck between the reamer and pipe and cause equipment failure, or the pipe to get stuck, etc.
When solid rock or mixed rocky conditions occur during the Jack and Bore process, the drilling slows way down, the machine requires greater push force at the entrance pit, the rocks can clog the drill head, etc.
Using the Hammer Bore System by EBI Drilling Services, the Down Hole Air Hammer (DTH) is full proof! The air hammer pulls the casing through the ground instead of pushing it, like a jack and bore system, and no matter the ground conditions, the casing will continue to advance forward as the DTH air hammer moves forward. No more digging unfavorable ground conditions or re-routing of pipe lines!
EBI Drilling Services has had multiple successful casing installations with their Hammer Boring solution under roadways, railways, paralleling roadways, Rivers, Bridges, etc.
