I. Introduction to HOLLOW GROUTED ANCHOR BOLTS 
Hollow grouting anchor bodies are essentially grouting pipes. After injecting grouting fluid, they not only anchor the rod but also, when the grouting pressure is high, some of the grout may seep into the fissures of the anchor hole, reinforcing the surrounding rock. A plug and a vent pipe should be installed in the upward hole.
The main components of hollow anchor rods: consists of hollow anchor rod body, plug, washer, nut, and anchor head (drill bit).
II. Hollow Grouting Anchor Rod Features:
● Hollow design, enabling the function of casting.
● Full grouting, pressure grouting available.
The rod body maintains good centrality; the mortar can fully encase the anchor rod, preventing rust and achieving the purpose of long-term support.
● Easy installation; no on-site threading required for mounting washers and nuts.
● Utilizes upward exhaust anchor heads, completely resolving the hollow anchor rod exhaust issue above the horizontal line.
III. Hollow Grouting Anchor Bolt Range:
Hollow anchor rods are suitable for medium geological conditions, temporary support, and advance support. They are primarily used in projects such as railways, highways, tunnels, mines, hydraulic hubs, slopes, embankments, bridge foundations, riverbank areas, high-rise building foundations, and reinforcement of structures. By pressure grouting through the hollow anchor rod body, it can achieve the purpose of consolidating fractured rock mass, intercepting groundwater, and preventing corrosion of the rod body, allowing for rapid formation of support forces and control of the stability of the surrounding rock.
4. Precautions for the construction of hollow grouting anchor bolts
Grouting workers must wear protective gear.
Thoroughly inspect machinery, equipment, and wiring to prevent electric shock injuries.
● Operators strictly follow the operational procedures.
The grouting worker and grouting pump operator must coordinate well.
Once casting is complete, close the valve first, then attend to the slurry pump.
● No pouring hole is to face people.Product Model Nominal OD*Wall Thickness (mm) Tensile Strength (KN) Yield Strength (KN) Tensile Elongation (%) Thread direction Pitch (mm) Anchor bolt hole diameter (mm) GQ-D25 25*3 ≥150 - ≥6 (No Chinese content provided, so the translation is not applicable.) 12.7 φ40-φ42 GQ-D25 25*5 ≥180 - ≥6 Left/Right-handed 10/12.7 φ40-φ42 GQ-D25 25x5 (Iron Standard) ≥153 ≥102 ≥21 Left/Right-handed 10/12.7 φ40-φ42 GQ-D25 25x7 (Iron Standard) ≥193 ≥128 ≥21 Left/Right-handed 10/12.7 φ40-φ42 GQ-D28 25*8 ≥280 - ≥6 Left/Right-handed 10/12.7 φ48 GQ-D32 32*6 ≥280 - ≥6 Left/Right-handed 10/12.7 φ50 GQ-D38 38*7 ≥350 - ≥6 Left/Right-handed 10/12.7 φ75 GQ-D51 51*8 ≥500 - ≥6 Left/Right-handed 10/12.7 φ80 Note 1.
