R51 Self Drilling Anchor Bolts, diameter is 51mm, the diameter to be chamfered is 55mm, and the chamfer length is 160mm. R51 Self Drilling Anchor Bolts are suitable for underground projects with larger borehole diameters, such as large tunnels, water conservancy projects, etc.
Self Drilling Anchor Bar is a new type of anchoring material. It can drill holes by itself, which greatly reduces the difficulty and labor intensity of installation. Since the self-drilling anchor uses a hydraulic arm to drill deep into the soil layer and then tensions the anchor, it generates self-stress, which greatly improves the bearing capacity of the anchor. The anchoring area of the self-drilling anchor is larger than that of ordinary anchors, and the bearing capacity is higher.
Self Drilling Anchor Hollow Bar R Thread
Features: The top and bottom of the teeth are both arc-shaped, and the thread continues in a wave shape.
Applicable scenarios of Self Drilling Anchor Hollow Bar R Thread:
Mainly used in construction scenarios where drilling and grouting are required, such as tunnel excavation, coal mine tunnel support, etc.
R-type thread has high bending resistance and bearing capacity, and can withstand the impact force during construction to ensure that the rod body will not be broken or plastically deformed.
Self Drilling Anchor System is mainly composed of hollow anchor rod body, nut, pad, connecting sleeve, centerer and drill bit. Self Drilling Anchor System integrates drilling, grouting and anchoring functions. It is suitable for broken and difficult-to-drill surrounding rocks. The casing wall is omitted during construction, which greatly improves the construction efficiency, shortens the construction period and reduces the overall construction cost.
To purchase Self Drilling Anchors Bolts T Thread. As an effective anchoring method, Self Drilling Anchors Bolts T Thread is suitable for complex, loose and broken geological conditions. It is widely used in rock support projects such as pre-support engineering, radial support engineering, slope stabilization, foundation support engineering, tunnel support engineering, soil nail wall, back-tension anchor retaining wall, etc. Self Drilling Anchors Bolts T Thread uses grooved threaded anchor rods, which can effectively bond the hollow rod body with grouting materials. It can be widely used in different projects, such as: mines, tunnels, hydropower stations, civil engineering, etc.
Self-Drilling Anchor Bolts can be divided into R-Thread Hollow anchor Bar and T-Thread Hollow anchor Bar. The outer surface of Self-Drilling Anchor Bolts is covered with continuous R-type or T-type threads, so that the rod body can be extended through a connecting sleeve. We can produce and supply various specifications of Self Drilling Anchor Bolt, if you want to buy or purchase, please feel free to inquire us.
T52 Self Drilling Anchor Bolt is a type of Self Drilling Anchors Bolts T Thread. T52 Self Drilling Anchor Bolt adopts T-thread design, with a concave groove on the top of the thread teeth, forming a double top line structure, and a flat surface connection. This design enhances the adhesion between the anchor body and the slurry and improves the anchoring effect.
T76 Self Drilling Anchor Bolt is a Self Drilling Anchor System designed for broken and difficult-to-drill geological conditions. The hollow rod structure of T76 Self Drilling Anchor Bolt can complete drilling and grouting operations simultaneously. The construction efficiency is about 50% higher than that of traditional steel pipe sheds, and it is especially suitable for large-scale projects such as tunnels and subways.
