Products advantages

1.Remove aging structures

Hollow grouting anchor rods can help remove damage in aged structures and achieve rapid reinforcement and recovery.

2.reinforced structure

The advantages of hollow grouting anchor rods in strengthening structures are very obvious. It can fix the surrounding soil layer by injecting grout and connect it to the foundation concrete, thereby increasing the bearing capacity of the structure.

Products use

Mainly used for systematic support of surrounding rocks with moderately good geological conditions.
In hard rock, horizontal bedding of rock layers, open joints and fissures with mud or groundwater development situations, steel expansion shell anchor rods can quickly form initial support, control surrounding rock deformation, ensure stability of surrounding rock, and then inject permanent anchoring. After drilling the hole with a rock drill to the designed depth of the anchor rod, install the steel anchor head onto the anchor rod body and place it into the hole. After installing the grout stop plug, cushion plate, and nut, reverse the anchor rod to make the expansion shell anchor head expand and grasp the hole wall, and then proceed with grouting
