Rock anchors fail when there is a loss of tension, corrosion, or inadequate installation. The hanger and bolt that make up the anchor assembly play a crucial role in maintaining the strength and stability of the anchor.
Stainless steel hangers are commonly used in rock anchors as they have excellent corrosion resistance properties. However, it is important to ensure that the stainless steel used is of high quality and meets the required specifications. Low-quality stainless steel can corrode quickly, leading to premature failure of the rock anchor.
The bolt used in the rock anchor is also critical. Wedge type expansion bolts are a popular choice as they provide strong anchorage and can be installed easily. However, the bolt must be installed correctly to ensure the expansion of the wedge is uniform and sufficient to provide secure anchorage.
Inadequate installation is a common cause of rock anchor failure. It is important to follow the manufacturer's instructions carefully and ensure that the anchor is installed to the required torque, depth, and alignment. Failure to do so can result in a loss of tension, which compromises the strength of the anchor.
Corrosion is another common cause of rock anchor failure. In addition to using high-quality stainless steel, it is important to ensure that the anchor is protected from exposure to corrosive materials. This can include coatings, such as zinc or epoxy, or the use of sacrificial anodes.
