400' River/Rock Bore in Darlington, OH

Utilizing an Astec 3238 and the Astec HDD50 Air Hammer, ClearPath completes a 400' rock bore under Moxahala Creek. The terrain on the project proved to be challenging. On the west side the setup area was restricted due to an active rail track. Then at approximately 250' the west wall of the creek dropped off 30' to the surface of the water. The creek was approximately 80' in width with a 15' rise on the east side and the exit needed to be done as soon as possible. Due to the limited steering that is typical with rock bores, the elevation changes and the desire to keep the project within budget, ClearPath incorporated the use of the Atlas Bore Planner to profile and plan the bore to 400' in length.

The Bore plan proved instrumental in completing the bore due to off air interference with the Eclipse locating system. The interference prevented us from receiving full readings and only providing us with an occasional pitch reading. However with the bore plan, we were able to bore using only the pitch changes. The bore plan had a target depth of 10' at the water edge and our exact depth was 10'1".
