Jackhammer loud Stock Photos and Images

October 2017: Here is a photo of the 11-ton impact hammer crews use to secure the last ten feet of each steel support column into place. The impact hammer sounds like a loud, monster-sized jackhammer. To reduce noise, crews use a quieter vibratory hammer to vibrate 90 percent of the pile deep into the sea bed first before finishing it off with the louder impact hammer. Each steel pile is up to 150-feet tall and 3-feet wide. They are designed to make Colman Dock safer in a major earthquake. Pile driving impact hammer 23965381938 o Stock Photo
