山区特高压输电线路钻探设备应用探讨

Discussion on Application of Drilling Equipment of UHV Transmission Lines in Mountainous Area

近年来,随着我国西电东送特高压输电线路发展规模扩大,新建线路勘察设计工作量大幅增加。其中西部地区输电线路主要沿山区走线,具有地形起伏大、高差大、交通条件差、水源缺乏等限制因素,结合山区特高压输电线路岩土工程勘察钻探作业的特点及相关规范规程,通过采用绍尔背包钻机及TGQ-15浅层取样钻机进行钻探作业,在实际应用中取得了良好的效果。

In recent years, the workload of investigation and design of power transmission lines has increased significantly along with the expansion of the development of the UHW power transmission project from West to East in China. The transmission lines in western region go mainly across mountainous and hills, of which there are terrain undulation and high difference with poor traffic, and water shortage of restricted factors. With combined characteristics of geotechnical engineering investigation and drilling operation in UHV transmission lines of mountainous area and relevant rules and regulations, the drilling operation is carried out by the Shaw backpack drill and the TGQ-15 shallow sampling drill. Good results have been achieved in practical application.
