Rapid crushing and digging construction method for power tower foundation pit in mountainous area
The invention belongs to the technical field of electric power construction, and discloses a mountainous area electric power tower foundation pit rapid crushing and digging construction method which comprises the steps that firstly, a down-the-hole percussion drill is adopted, and a plurality of continuous side holes are drilled along the edge of a foundation pit area; and then a plurality of splitting holes are drilled in the foundation pit area, and the splitting holes are distributed at intervals. According to the method, drilling can be conducted to the designed depth at a time, the labor cost is saved, and the drilling construction efficiency in the foundation pit digging process is greatly improved; according to the construction method, the construction sequence of firstly drilling the continuous side holes and then drilling the splitting holes is adopted, so that a flat foundation pit wall can be conveniently obtained in a foundation pit area, and the influence of subsequent rock splitting on the stability of a rock stratum around the foundation pit is ensured.
本发明属于电力施工技术领域，公开了一种山区电力塔架基坑快速破碎掏挖施工方法，先采用潜孔冲击钻机，沿基坑区域边缘钻连续的多个边孔；然后在基坑区域内部钻多个劈裂孔，多个劈裂孔间隔分布。本发明能够一次钻孔至设计深度，节省人工成本，且极大提高基坑掏挖过程中的钻孔施工效率；本发明采用先钻连续边孔，再钻劈裂孔的施工顺序，便于在基坑区域获得平整的基坑壁，并确保后续的岩石劈裂影响基坑周边岩层的稳固性。
