After a recent storm in Stevensville, Maryland, some telephone and electrical power posts experienced movement from the rough winds and rising water. The poles were not damaged to the point of replacement; however, remedial action was required to insure that there would be no further damage or movement. Helical Piles were chosen as a tie-down system. They were selected since they were the least intrusive method of deep foundation piling in a wetland area as well as the ease of getting them installed to the correct angle to attach them to the power posts.
Project Summary:
- Helical Pile Type: RS 4500.337
- # of Helical Piles: 12
- Location: Stevensville, MD
- Installation Depth: 130′
- Ultimate Pile Capacity: 70 kips
- Equipment Used: Long Reach Kobelco Excavator, 16K Drive Head
- Challenge/Unique Aspect: Intrusion into the sensitive wetland environment was discouraged. The installation needed to be done from the road to avoid any disturbance. A large, long reach boom excavator with a drive head was able to reach out over the road and install the anchors used to tie-down the poles.
