self brilling anchor bar

self brilling anchor bar adopts good thick-wall seamless steel pipe material, perfect and quick surface thread forming process and well-made accessories, truly realizing the unity of self-drilling bolt drilling, grouting, anchoring and other functions.

1) There is a drill with strong penetrating force in front of the bolt, which can easily penetrate all kinds of rocks under the action of general rock drilling machinery.

2) The anchor bolt has continuous international standard wave thread, which can be used as drill pipe with drill bit to complete the drilling into anchor holes.

3) The bolt body as drill pipe does not need to be pulled out, in which the empty can be used as a grouting channel, from the inside to the outside for grouting.

4) The high-efficiency stop plug can make the grouting maintain strong grouting pressure, fully fill the void, and fix the broken rock mass. The high-strength backing plate and nut can evenly transfer the stress of deep surrounding rock to the surrounding rock, so as to achieve the purpose of mutual support between surrounding rock and bolt.

5) The high strength coupling sleeve processed by mechanical cutting technology makes the self-drilling bolt have the characteristics of lengthening while drilling, so that it can be applied to the relatively narrow construction space, and realizes the design idea of strengthening the surrounding rock with long bolt.

6) Due to the trinity function of the bolt, the anchor hole can be formed and the effect of anchoring and grouting can be ensured without special techniques such as casing wall protection and pre-grouting during construction under various surrounding rock conditions.
