凿岩台车在水电工程地下厂房施工中应用已经很普遍,其高效、安全、可靠且机动灵活的特性已经成为不可或缺的重要手段。由于各种原因,国内水电工程施工中的台车用于地下工程开挖较少,主要用于系统锚杆支护造孔和随机锚杆支护造孔。文章总结了清远抽水蓄能电站地下厂房系统主副厂房锚杆造孔施工中凿岩台车应用的成功经验。
Drilling rigs have been widely used in the construction of underground powerhouse hydropower projects. Their high efficiency, safety, reliability and flexibility have become indispensable tools. Due to various reasons, the trolley used in the construction of hydropower projects in China is used for excavation of underground works and is mainly used for making holes in system bolts and making holes in random bolts. This paper summarizes the successful experience of rock drilling trolley application in the construction of anchor rod in the main and auxiliary plant of underground powerhouse system of Qingyuan Pumped Storage Power Station.
