Injecting Cement Grout during Horizontal Directional Drilling (HDD) Pullback
New Pipeline Technologies, Security, and Safety, 2003A 24-inch diameter natural gas pipeline traversed the Sacramento-San Joaquin River Delta in 2001 and included three HDD crossings of elevated rivers or sloughs. Crossing lengths varied from 1400 to 1800 feet. Typical profiles provided for 75 feet of cover beneath the channel bottom resulting in total depths of about 100 feet beneath the entry and exit ...
