Detail Instruction
1.roof-bolt head: the head of the barbs  anchor bolt may be positioned in the drilled hole, and to ensure a good rod  centered.
2.roof-bolt body: assembly of the most  important building in the anchorage and support plays a major role.
3.grouting stopper: In the process of  maintaining the grouting pressure grouting, the slurry sufficiently fill the  gap into the surrounding rock.
4.plate: withstand greater stress of  surrounding rock.
5.the nut: the rock stress concentration to  the backing plate.
Characteristic
1.take the anchor and grouting pipe  function combined when grouting,it is grouting pipe, after the end note pulp  becomes an anchor without allocation.
2.the hollow design allows the functions to  achieve the grouting pipe, to avoid the traditional construction process  grouting mortar tube allocate the loss caused.
3.full grouting pressure grouting and to  achieve improved project quality.
4.due to the role of various accessories,  the centering rod is very good, mortar anchor body length can be wrapped to  avoid the risk of corrosion, to achieve the purpose of long-term support.
5.easy installation, no on-site processing  thread, you can easily install plate and nut.
6.combined with supporting special  injection pump and bolt grouting process, is the only completely solve the  traditional anchor supporting many problems anchoring system.
Construction technics
1) Drilling: Drilling and drilling machines  with ordinary hole clean
2)Insert roof-bolt: the installed anchor  head insertion hole hollow grouting anchor, anchor bolt head barb immediately  caught.
3)Install grouting stopper, plate and nut.
4)Connect grouting machine: through rapid  grouting joints will end and the selected anchor grouting machine connection.
5)Grouting: Grouting start the machine,  such as the need for improved pressure grouting rock structure, just to be  increased to the design pressure gauge pointer when you can.
