2. INTRODUCTION
Soil nailing is a technique used to
reinforce and strengthen existing ground
Soil nailing consists of installing closely
spaced bars into a slope or excavation as
construction proceeds from top down
The grouted nails increases shear strength
of overall soil mass.
3. TYPES OF SOIL NAIL
Screw anchor soil nail
Grouted soil nail
4. PROCEDURE OF SOIL NAILING
Excavate small cut
Drill hole for nail
Install & grout nail
Place drainage strips, initial shotcrete
layer & install bearing plates
Repeat process to final grade
Place final facing on permanent walls

6. IDEAL CONDITIONS FOR SOIL
NAILING
Height of excavation
Excavation Face Inclination
Type of soil
Nail length
Nail inclination
Nail diameter
Grouted hole diameter
11. COMPARATIVE STUDY OF SOIL

14. CONCLUSION
Soil nailing is a potential solution of
landslide problems as it is economical and
also applicable in seismic zones.
It can solve the problem of residential
area up to a great extent.
It can be used in wide soil types.
