  1、一般采用轻型手持式凿岩机钻凿锚杆孔。

  2、钻孔作业一般宜采用自上而下的施工顺序进行,在此过程中可对尚未完全清除的影响施工安全的坡面浮土、浮石进行再次清除。

  3、一般应在钻孔前或钻孔的同时,在孔口处凿一满足设计要求的凹坑,其作用主要在于使穿过该位置处锚杆外露环套的支撑绳能贴紧坡面,因此,其尺寸大小能使锚杆外露环套的顶部内缘不高出孔口处地面即可。以下两种情况下是不必人工开凿凹坑的,一是锚孔本身处于满足要求的天然凹坑处,二是监近锚孔间的坡面凸起或为孤危石时,因为在这一情况下即使锚孔处的支撑绳将悬空,但在跨越凸起体时它也是能贴紧坡面的。

  1、钢丝绳锚杆的安装与普通钢筋砂浆锚杆相似,为保证砂浆体与孔壁的良好黏结以及对锚杆体的握裹,同样需要进行洗孔和杆体对中。由于钢丝绳锚杆的柔性和扁平特征,在锚固深度不大于3m的情况下,可以很容易地通过人工搅动杆体来使孔内浆体均匀饱满,当锚固深度更大时,一般应考虑采用机械注浆。

  2、理论上讲,支撑绳的长度是可以不受限制的,甚至为了减少固定点数量,其长度越长越好,但是,由于成都边坡防护网孔口凹坑的存在,张紧状态下的支撑绳并不是一根直线,过长的支撑绳可能形成过大的张拉阻力而很难张紧,为此,一般宜将单根支撑绳的最大长度控制在30m左右;此外,当纵横支撑绳设计规格不同时,单根支撑绳应在同排或同列中安装,只有在设计规格相同时,为避免边角处过短的支撑绳造成材料浪费并留下过多的固定连接点,可以考虑从排转向列或从列转向排来安装。

  3、对于围护系统,由于并不要求张紧支撑绳,因此在易于搬运和安装的前提下,可以使单根支撑绳尽可能地长。

  1、从施工安全和减少裁剪工作量考虑,格栅的铺挂一般应从上向下进行,网块间应重叠一至两排网孔宽度并用扎丝扎结(扎结间距一般为1m左右),应使网块尽可能平展并紧贴坡面。
