What is Characteristics of Self drilling Anchor Rod?
The self drilling hollow grouting anchor rod adopts good thick walled seamless steel pipe material, perfect and fast surface thread forming technology, and well crafted accessories, truly realizing the unity of self drilling anchor rod drilling, grouting, anchoring and other functions.
There is a strong penetrating drill bit in front of the self inserting hollow grouting anchor rod, which can easily penetrate various types of rocks under the action of general rock drilling machinery.
With continuous international standard waveform threads, it can be used as a drill rod to complete drilling and anchor holes with drill bits.
The anchor rod body of the drill rod does not need to be pulled out, and the empty space can be used as a grouting channel for grouting from the inside out.
The high-efficiency grout stopper enables the grouting to maintain a strong grouting pressure, fully fill the gaps, and fix the fractured rock mass. The high-strength pad and nut can evenly transmit the stress of the deep surrounding rock to the surrounding rock, achieving the purpose of mutual support between the surrounding rock and the anchor rod.
