缝管锚杆

日期:2020-06-09 19:12:18 / 人气:82

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.

Friction stabilizer (slit rock bolt)has many advantages  such as initiative reniforce,surrounding rock with full bolt,reinforce anchor immediately and etc. The bolt is installed in a hole which has smaller diameter than it. It can immediately process radial pressure to the hole to prevent rock falling. When surrounding rock is shaked by explosion, anchor capacity increasesed higher and supporting effect is perfect.

使用方法

Manual

(1)依据设计要求确定锚杆孔位,用钻机具打孔。

drill a hole According to the requirement of design

(2)用压风吹尽孔内岩粉。

Clean rock powder in the hole with compress air

(3)杆体装上锚盘,用冲击钻将锚杆打入孔中。

Mounting plate through rod,then push rod into hole with shock drill machine

技术优点
