Hollow Bar Soil Nails made by Sinorock for civil work
is a method of earth reinforcement. It can be used as foundation repair or construction of soil slopes.
Advantages of soil nailing:
1.Installation is practically free from vibration. Less noise and fewer traffic obstructions.
2.The drill rigs can install soil nails at any angles. This is ideal for tight spaces engineering.
3.Soil nail can be used on new constructions, as temporary structures or remedial measure to treat unstable natural soil slopes.
4.Soil Nailing is relatively rapid and uses typically less construction materials than ground anchor walls.
Action principle:
The shear strength of soil is very low, and its tensile strength almost can be ignored.
Soil-nailed wall technology is a kind of soil reinforcing method by placing with steel reinforcing bars and concrete rods.
In comparison of cohesive soil slopes, soil-nailed wall can avoid sudden collapse while loading. Soil nail walls not only postpone plastic deformation, but also have obvious progressive deformation and cracking failure.
Self-drilling Hollow Bar Soil Nailing:
In general, the reinforcing bars are installed into a pre-drilled hole and then grouted into place. For , the drilling and grouting are simultaneous.
If the soil strengthened systems are used as permanent structures, the ductility of hollow bar soil nails is also required. Infrastructure construction always emphasizes safety and stability.
