R32 Self Drilling Hollow Bar
  • R32 hollow bar anchors consist of hollow bar, drill bit, coupling, packer, plate and nut, combine grouting and drilling together and adapt to several construction situations and different geological conditions.

Function:

1. Instead of the traditional mortar anchor bolt, it is used for radial reinforcement.
2. It can be used to reinforce unstable slope.
3. The foundation reinforcement of construction.

Features:

1. It can solve defects that traditional mortar anchor is unfilled grouting during the construction and can’t grout under pressure.
2. The operation is simple with low cost, convenient construction and an obvious effect.
3. It can realize grouting under pressure and reform foundation surrounding rock conditions.
