The function of Rock bolt nut in geotechnical engineering mainly includes the following aspects ‌ :

‌ applying preload ‌ : The bolt nut exerts preload on the bolt by pressing the plate to ensure that the bolt can be firmly fixed in the rock and soil mass after installation. This kind of preload can effectively control the deformation of surrounding rock and enhance the stability of supporting structure ‌

‌ transfer stress ‌ : when the surrounding rock deformation occurs, the bolt nut transfers the load to the bolt body through the support plate, increases the working resistance of the bolt, and thus controls the further deformation of the surrounding rock. This stress transfer mechanism enables the bolt system to provide sufficient support when the surrounding rock deforms ‌

‌ ensure solid connection ‌ : The bolt nut is made of high-strength alloy material and has excellent tensile, shear and fatigue resistance after precision forging and heat treatment. Its surface has been specially treated to enhance the corrosion resistance, ensure the tight fit between the nut and the anchor rod, and effectively prevent the risk of loosening and falling off ‌

to meet different engineering requirements ‌ : bolt nuts can be customized according to engineering requirements to meet different geological conditions, different bolt specifications and different support requirements. This flexibility allows bolt nuts to play an important role in a variety of complex geotechnical engineering ‌
