Mountainous area power transmission line iron tower foundation construction equipment and method
The invention discloses construction equipment and method for a power transmission line iron tower foundation in a mountainous area, the construction method comprises two working conditions of drilling an anchor rod hole with the diameter of phi 90-150 mm and excavating a large-diameter base hole, and drilling of the anchor rod hole with the diameter of phi 90-150 mm is completed by directly utilizing a pneumatic down-the-hole impact hammer in the state that a drill arm is used; the large-diameter base hole excavation comprises the following steps that (1) according to the diameter requirement of an excavated foundation pit, circumferential drilling is completed through a drilling machine, and rock needing to be excavated in the middle is isolated from surrounding rock; (2) a drill arm is replaced with a mechanical arm, a breaking hammer is installed, and middle rock is broken; (3) the breaking hammer is replaced by a grab bucket, and broken stones are grabbed out; and (4) the step (2) and the step (3) are repeated until the foundation pit with the set depth is completed. When a large-diameter base hole is excavated, the workload is large, the working efficiency can be greatly improved by utilizing the equipment, and the construction safety is guaranteed.
本发明公开了一种山区输电线路铁塔基础施工设备及方法，其施工方法包括φ90‑150mm锚杆孔钻孔和大直径基孔开挖两种工况，对于φ90‑150mm锚杆孔钻孔，是在使用钻臂状态下，直接利用气动潜孔冲击锤完成；大直径基孔开挖包括如下步骤：(1)按照开挖基坑直径要求，用钻机完成周圈钻孔，将中间需要开挖的岩石与周边岩石孤立；(2)将钻臂替换成机械臂，安装破碎锤，将中间岩石破碎；(3)将破碎锤换成抓斗，将碎石抓出；(4)重复操作步骤(2)、(3)，直到完成设定深度的基坑。大直径基孔开挖时，工作量大，利用本发明的设备可以极大的提高工作效率，并且保证了施工的安全性。
