Building a Tall Self-Standing Retaining Wall into a Steep Slope with Pressed-In Pipe Piles
Steel pipe piles can form deep and robust excavation support during construction and subsequently reliable earth retaining walls. In the case of the Orio Railway Grade Separation Project in the densely populated urban area of western Japan, a 14.8 m (48.5 ft) high cantilevered earth retaining wall was built with 1,000 mm (39.4 in.) diameter and 6.0–19.5 m (20–64 ft) long pipe piles. They were installed into a very steep slope where the construction access was very limited. Each pile was rotated and simultaneously pressed into a sandstone layer through a shotcrete surface with a cutting shoe at the pile tip, enabling this otherwise very difficult piling work. Both the piling machine and its support crane moved forward and backward on the already installed piles by using the line of the piles as a secure and safe construction staging area as well as an access path on the steep slope, while trains were passing by on the rail tracks at the bottom of the slope.
