Reinforced Cut Slope Structures (RCSS)

RCSS is defined as Reinforced Cut Slope Structure. RCSS emphasizes the installation of Soil Nails and Self- drilling Anchors for stabilizing the slope.

Soil Nailing consists of reinforcing the soil mass by introducing a series of thin elements called ‘Nail’s to resist tension, bending, and shear forces. The reinforcing elements are made of round cross-section steel bars called Nails. Nails are installed sub- horizontally or horizontally into the soil mass in pre-bored holes, which are grouted along their total length to form ‘Grouted Nails’ or simply driven into the ground, called ‘Driven Nails’. It is proposed to have grouted nails at this project site.

The Self-Drilling Hollow Bar Anchor System is comprised of a hollow threaded bar with an attached drill bit that can perform drilling, anchoring, and grouting in a single operation. The hollow bar allows air and water to freely pass through the bar during drilling to remove debris and then allow grout to be injected immediately after drilling is completed. Grout fills the hollow bar and completely covers the entire bolt. Couplers can be used to join hollow bars and extend the bolt length while nuts and plates are used to provide the required tension.
