管缝式锚杆系列
slit wedge tubing bolt series
管缝式锚杆又名缝管锚杆,该锚杆是主动加固围岩全锚固立即承载等优点,安装于比管径稍小的钻孔中,可立即在全长范围内对孔壁施加径向压力防止围岩下滑.在爆破振动围岩位移情况下,锚固力明显增大,支护效果更加理想.
slit wedge tubing bolt , also known as seam anchor bolt has many advantages such as consolidate a surrounding rock on self"s own initiative, active reinforcement anchorage and immediately bearing etc. the bolt is installed in a hole which has smaller diameter than it. it can immediately impose full range radial pressure on the wall of the hole to prevent rock fall. in case of blasting vibration displacement of surrounding rock, anchoring increases significantly, and supporting effect is ideal.
该产品主要销往澳大利亚、美国、印尼、菲律宾等国家。
the products are mainly exported to australia, the united states, indonesia, the philippines and other countries.

管缝式锚杆钻孔孔径推荐计算方法：
the best consumption of feed tube diameter drilling anchor
岩层中：
the rock stratum
钻孔直径=（0.9-0.95）×锚杆直径
borehole diameter=（0.9-0.95）×bolt diameter
锚杆钻孔深度:锚杆长度+100mm
anchor drilling depth: anchor length+100mm
钻孔偏斜率＜1%
drilling partial slope＜1%
煤层中：
coal seam
钻孔直径=(0.9-1.00)×锚杆直径
borehole diameter =（0.9-1.00）×bolt diameter
锚杆钻孔深度:锚杆长度+200mm
anchor drilling depth: anchor length+200mm
钻孔偏斜率<1.5%
drilling partial slope＜1.5%

使用方法
method of application
(1)依据设计要求确定锚杆孔位，用钻机具打孔。
according to the re of design, drill a hole with punching
(2)用压风吹尽孔内岩粉。
use wind pressure to blast the rock powder of the hole
(3)杆体装上锚盘，用冲击钻将锚杆打入孔中。
rod anchor plate fitted with a shock will bolt into the hole drill
技术优点
technical advantages:
高强托盘其承载力大于杆体承载力，挡环拉脱力大于杆体的承载力。
high-strength tray bearing capacity, the rod body than retaining ring pull off the bearing force than pole
