Sinorock® self drilling rock anchor system can be used as dust ejector tube before grouting. It can eliminate dust in the drilling hole. Grout slurry can be erupted out from drill bit, then it can fill surrounding drill hole and stratum fracture. It makes self drilling rock anchor combine with surrounding soil texture, forms concrete column with steel pipe,and then has the effect of reinforcement. Nuts is a part of Sinorock® self drilling rock anchor bolt system，which consists of rock anchor, plate, nut, coupling, drill bit and centralizer.
1. It adapts to several projects, such as mine, hydro-junction, slope, bridge base, river bank, high-rise building, construction reinforcement and so on.
2. The management of geological disaster, such as: ground subsidence, collapse, landslide and so on.
3. The reinforcement of coal mine, metallurgy and war industry projects.
1. Mechanical processing, high precision, stable quality
2. The strength is equal to the self drilling rock anchor.
3. T-thread nut adopts collar design, which is more easier for installation on-site construction.
4. According to the construction needs, Sinorock provides various nuts for the customers to choose.
Hex nut: For the construction occasion where the direction of drilling is perpendicular to the rock surface or the deviation angle is about ±7°.
Spherical nut: For the construction occasion where the the deviation angle of drilling direction and the rock is about ±20°.
