Machine tool for cutting off anchor rod (anchor cable) in deep foundation pit of subway station and construction process
The invention discloses a machine tool for cutting off an anchor rod (anchor cable) in a deep foundation pit of a subway station and a construction process. The machine tool comprises a hooking pulling piece, a cutting tool used for cutting the anchor rod (anchor cable) is arranged on the top end face of the hooking pulling piece, an insertion opening is formed in the bottom of the inner wall of the hooking pulling piece, the cutting tool is in insertion fit with the insertion opening and is in clearance fit with the insertion opening, and a hydraulic cylinder used for driving the cutting tool to perform cutting in a reciprocating mode up and down is arranged on the top end face of the hooking pulling piece. According to the machine tool, the situation that due to the fact that the anchor rod (anchor cable) is large in diameter and stable in material, when the anchor rod (anchor cable) is twisted off directly through a rotary drilling rig, a foundation pit collapses can be avoided; the problems that at present, when the anchor rod (anchor cable) is twisted off directly through the rotary drilling rig, time is consumed, more energy is consumed, and the safety is poor are solved; and the hooking pulling piece and the cutting tool can be repeatedly used, and compared with a rotary drilling rig which forcibly twists off the anchor rod (anchor cable), the hooking pulling piece and the cutting tool are less in abrasion and high in utilization rate.
本发明公开了一种地铁车站深基坑内锚杆(锚索)切断机具及施工工艺，包括钩拉件，所述钩拉件的顶端面上安装有用于裁剪锚杆(锚索)的剪切刀，所述钩拉件的内壁的底部上开设有插接口，所述剪切刀与所述插接口插接适配并与之间隙配合，所述钩拉件的顶端面上安装有用于驱动剪切刀沿上下往复裁剪的液压缸；本发明中能够避免因锚杆(锚索)自身直径较大材质稳固直接使用旋挖钻对锚杆(锚索)进行扭断导致基坑塌孔的状况，解决了目前使用旋挖钻直接扭断锚杆(锚索)耗费时间较长、消耗能源较多以及安全性不佳的问题；且钩拉件和剪切刀能够重复使用，相对于旋挖钻强制对锚杆(锚索)进行扭断，钩拉件和剪切刀的磨损少，利用率高。
