How to Package and Store Pipe Spacing Anchors?

Tubular bolt anchors are commonly used in underground operations to prevent the slippage of surrounding rock. Made of steel pipes, they feature a crack at the pipe end, which allows them to fit into drilled holes smaller than their diameter. Upon application of force, the crack expands to create friction, effectively securing the surrounding rock.

Tie rods are typically packaged in bundles, with each bundle containing 10 rods. Naturally, the trays are also tied together in groups; generally, trays are bundled in groups of 50.

After securing the tie rods and plates, timely waterproofing and anti-corrosion measures should be taken to prevent the rods from suffering corrosion.

Modern tube bolt products often suffer from corrosion, significantly reducing their effectiveness. This is primarily due to the bolts' long-term exposure to air, compounded by the influence of a humid environment, which easily leads to rusting. Additionally, some manufacturers may cut corners during the production of tube bolt products, resulting in a decline in product quality.

To address these issues, the problem can be resolved during construction by injecting mortar into the anchor bolt holes, which effectively reduces crack shrinkage. During the injection process, it is important to ensure that the mortar is not too wet to prevent leakage.

Additionally, regular inspections of ground pressure in mines are required. If cracks in the formed mortar are detected, the application of grout should be repeated immediately. This method is highly effective in addressing the corrosion issue of pipeline bolt anchors.
