一种输变电线路基础成孔垂直导向与除尘两用装置 技术领域
本发明涉及一种垂直导向与除尘两用装置，具体讲涉及一种输变电线路基础成孔垂直导向与除尘两用装置。
背景技术
输电是用变压器将发电机发出的电能升压后，再经断路器等控制设备接入输电线路来实现。按结构形式，输电线路分为架空输电线路和电缆线路。架空输电线路由线路杆塔、导线、绝缘子、线路金具、拉线、杆塔基础、接地装置等构成，架设在地面之上。
山区岩石地段的输电线路工程中,岩石锚杆基础发挥了原状岩体的力学性能,具有较好的抗拔性能,是值得推广的一种新型环保基础。水泥砂浆或细石混凝土与锚筋注入岩孔内形成的输电线路岩石锚杆基础，使得锚筋与岩体胶结成整体，承受上部结构荷载。岩石锚杆基础减少了基础混凝土用量、土石方开挖量，降低了水泥、砂石、基础钢材及弃土的运输量，能显著降低运输工程量，特别适用于地形复杂的高山地区。同时，也因显著减少了人工开挖或爆破作业对基础周围岩石基面、林木植被的损害，具有较好的环保效益。
但是，在山区输变电线路施工过程中，环境条件相对较恶劣，导致很多设备无法运抵施工现场，因此在锚杆孔的开挖过程中缺少相应的设备来保证锚杆孔的施工质量。
目前，在锚杆孔的钻孔过程中，孔的垂直定位需要施工人员手扶导正，钻孔的垂直度也无法保证，会对施工人员的人身安全构成了隐患，；同时，钻孔过程中产生的大量灰尘无法得到有效的收集和处理，对施工人员的健康造成危害。
