Self-Drilling Anchor Bolts

To buy Self-Drilling Anchor Bolts refers to a slender rod body that penetrates deep into the rock and soil and controls the deformation of the rock and soil, and may include components such as pads and nuts. As a tensile member deep into the stratum, Self-Drilling Anchor Bolts are connected to the engineering structure at one end and deep into the stratum at the other end. The whole anchor bolt is divided into a free section and an anchor section.

We can produce and supply various specifications of Self Drilling Anchor Bolt, please feel free to inquire us.

Product Description

The anchor body of Self-Drilling Anchor Bolts is the grouting pipe. After the grouting liquid is injected, it can not only anchor the rod body, but also some of the grouting liquid will penetrate into the cracks of the anchor hole when the grouting pressure is high, playing a role in reinforcing the surrounding rock. The upward hole should be equipped with a grout stopper and an exhaust pipe. Its function is to increase the bonding and friction between the anchor body and the soil layer, increase the pressure bearing effect of the anchor body, and transmit the tension of the free section to the deep soil.

As a tensile member deep into the stratum, Self-Drilling Anchor Bolts are connected to the engineering structure at one end and deep into the stratum at the other end. The whole anchor bolt is divided into a free section and an anchor section. The free section refers to the area where the tension at the anchor bolt head is transmitted to the anchor body, and its function is to apply prestress to the anchor bolt; the anchor section refers to the area where the cement slurry bonds the prestressed tendons to the soil layer, and its function is to increase the bonding friction between the anchor body and the soil layer, increase the bearing pressure of the anchor body, and transmit the tension of the free section to the depth of the soil.
Self-Drilling Anchor Bolts are used for system support of surrounding rocks with moderately good geological conditions.
