May 16, 2014 FRP Hollow Grouting Bar Used in Tunneling Support XY81 - Xuyao Products Made In China, China Manufacturer. INTRODUCTION Hollow self- drill ing bolt is a kind of effective means of anchorage . Hollow grouting bolt is appli ed to geological conditions and other engineers for permanent support and advancing support. We can achieve the aim of c onsolidati ng fractured rock mass,
strength of the rock mass so that it becomes self-supporting. Rock support generally combines the effects of reinforcement, by such elements as dowels, tensioned rock bolts and cables, and support, with shotcrete, mesh and steel sets which carry loads from individual rock blocks isolated by structural discontinuities or zones of loosened rock.

FRP Fiberglass Rock Bolt Used in Mining Support XY60 - Xuyao Products Made In China, China Manufacturer. INTRODUCTION FRP bolt is a kind of bolt which mainly consists of unsaturated resin as the basic materials and fiberglass as composite material s. As we all know, bolts are the fundamental parts of the contemporary coal mine tunnel support, they make the surrounding rock of the tunnel
in the United States. They are rock bolts, steel sets, and shotcrete. Shotcrete is a pneumatically applied large-aggregate concrete. The need for a secondary lining in a tunnel supported by shotcrete depends on the purpose of the tunnel. Table 1 gives pres ent use of the three types of primary support systems for rock tunnels in various rock
Rock bolt reinforcement can be used in any excavation geometry, is simple and quick to apply, and is relatively cheap. The length of the rock bolt can be varied, which is depended on the reinforcement requirements.

Rock bolt assemblies are packaged as complete, ready-to install units. The stud portion of the Rock Bolt Assembly comprises a deformed steel bar with a cold-rolled thread at one end. The Tyta Bolt has a 6mm pitch knuckle thread, with proprietary form, from lengths of
installation. For short term applications the bolts are generally left ungrouted. For more permanent applications or in rock in which corrosive groundwater is present, the space between the bolt and the rock can be filled with cement or resin grout. Dowels or anchor bars generally consist of deformed steel bars which are grouted into the rock.
