Hollow grouting anchor rods, compared to conventional cement mortar anchor rods,

Hollow Grouting Anchor BoltEarly research was conducted internationally, and was later introduced to our country.In the late 1990s, and across the nation, we focused on improvement and development. In recent years, our services have been extensively utilized to support the country's design and construction of hydropower and water projects, making underground chambers and high边坡 projects more cost-effective and safer. We hold priority in the design and construction advice for high-rise buildings in projects related to water and electricity, rail, and highway infrastructure.
Compared to ordinary cement mortar anchor rods, this product saves additional grouting pipes and exhaust vents, drilling, Integrated buoy and anchor, the construction process is simple and safe, reducing labor costs.
Hollow grouting bolt and shotcrete combined system support, offering both rigidity and flexibility. Moderate combination optimizes the support and bracing capabilities of anchor shotcrete support. The role of consolidated rock. This has significantly reduced the construction cost.
Hollow grouting bolt versus a standard cement mortar bolt with the same cross-section. The slurry can fully encase the anchor rod, with its surface enveloping the surrounding rock, exceeding the bending and shearing forces it is designed to bear. The adhesive strength is greater. Self-grouting and pre-stressed hollow grouting anchor rods can apply pre-stress to the surrounding rock, effectively preventing the deterioration of surrounding rock strength due to unloading.
