DESCRIPTION
Threaded Anchor Self Drilling Anchor Bolts Hollow Anchor Bar.
Anchor is the rods system structure for rock and soil reinforcement.
Through the longitudinal tension of the bolts body, the shortcoming that the tensile capacity of rock and soil is far lower than the compressive capacity is overcome.
On the surface, Hollow Anchor Bar seems to limit the separation of rock and soil from the original body.
Macroscopically, Hollow Anchor Rod increases the cohesion of rock and soil mass.
From a mechanical point of view, it mainly improves the cohesion C and internal friction angle φ of the surrounding rock mass.
In essence, the anchor bolt is located in the rock-soil body and forms a new complex with the rock-soil body. The bolts in this complex are the key to solving the low tensile capacity of the surrounding rock mass. As a result, the bearing capacity of the rock and soil itself is greatly enhanced.
Anchor is the most basic part of roadway support in contemporary underground mines. It binds the surrounding rock of the roadway together so that the surrounding rock can support itself.
Anchor rods are not only used in mines, but also in engineering technology for active reinforcement of slopes, tunnels, dams, etc.

Features of self-drilling anchor rod:
1) There is a bit with strong penetration force in front of the anchor rod, which can easily penetrate all kinds of rocks under the action of general rock drilling machinery.
2) The anchor rod has continuous international standard wavy thread, which can be used as drill pipe and drill bit to complete drilling and anchor hole.
3) The anchor rod body used as drill pipe does not need to be pulled out, and the hollow can be used as a grouting channel for grouting from inside to outside.
4) High-efficiency grout stop plug enables the grouting to maintain a strong grouting pressure, fully fill the gap, fix the broken rock mass, and high-strength backing plate and nut can evenly transfer the stress of the deep surrounding rock to the surrounding rock, so as to achieve the purpose of mutual support between the surrounding rock and the bolt.
5) The high-strength coupling sleeve processed by mechanical power cutting technology makes the self-drilling anchor rod have the characteristics of lengthening while drilling, making it suitable for a narrow construction space, and realizing the design idea of strengthening surrounding rock with extra-long anchor rod.
6) Due to the three-in-one function of the anchor rod, it can form the anchor hole and ensure the anchoring and grouting effect without special techniques such as casing wall protection and pre-grouting when it is constructed under various surrounding rock conditions.
