管缝式锚杆概述

管缝式锚杆是一种全长锚固,主动加固围岩的新型锚杆,它立体部分是一根纵向开缝的高强度钢管,当安装于比管径稍小的钻孔时,可立即在全长范围内对孔壁施加径向压力和阻止围岩下滑的摩擦力,加上锚杆托盘托板的承托力,从而使围岩处于三向受力状态,并实现岩层伟大。在爆破振动围岩锚移等情况下,后期锚固力有明显增大,当围岩发生显著位移时,锚杆并不失去其支护抗力,它比涨壳式锚杆有更好的特性。 

管缝式锚杆规格

1、外径(毫米):Φ30,Φ33,Φ40,Φ43(±0.5);
2、长度(毫米):12001500180020002500
3、材质:Q23516Mn20 Mnsi

管缝式锚杆工作原理

将管缝式锚杆安装于比管径小一些的钻孔中,这时,将对围岩施加三种力,一种是在管缝式锚杆全长范围内对孔壁的径向压力,一种是摩擦力,用以阻止围岩下滑,还有一种是管缝式锚杆托盘托板的承托力,这三种力使得围岩更加稳固。

管缝式锚杆技术特点

l、原料采用高强合金带钢;
2、安装简单;
3、无需锚固剂;
4、锚杆与岩体的摩擦力大;
5、具有很高的抗碱、抗拉强度;
6、配有高强托盘,托盘受力均匀;
7、巷道高度大于锚杆长度。

管缝式锚杆技术要求

1、缝管锚杆表面应平整,无严重拉伤,锈蚀。焊缝应无裂纹,无气孔夹渣,不允许烧穿管壁。托盘在杆体上应能自由移动。挡环接口与管缝开口相互错位170o190o为宜。
2、挡环焊缝拉脱力≥80kN,杆体极限抗拉力≥110kN,初锚力≥25kN/m,托盘承载力≥65kN.

管缝式锚杆技术性能

1、初始锚固力:3~7吨;
2、管环拉脱荷载:8~10吨;
3、锚杆管抗拉断能力:12~13吨;
4、耐腐蚀性能比A3钢高20~30%,利于长期使用。

管缝式锚杆使用方法

1、依据设计要求确定锚杆孔位,用钻机具打孔。
2、用压风吹尽孔内岩粉。

3、杆体装上锚盘,用冲击钻将锚杆打入孔中。
