  • Construction of Anchor Cable Holes at Yunnan Xiaowanshui Electricity Station


    Construction of Drainage Holes for Electricity Station in Longtan Water, Guangxi

  • Introduction The YG-80 engineering drilling rig is a fully hydraulic driven power head drilling rig. For high-tech products in Jiangsu Province. Suitable for the construction of large tonnage prestressed anchor holes and drainage holes in water electrical stations, railways, and highway slopes, as well as for the prevention and control of geological disasters such as landslides and rock collapses. It is also suitable for the construction of small water wells and high-pressure rotary jet drilling. At Xiaowan in Yunnan, Longtan in Guangxi, Nuozhadu and Jinghongshui Electric Stations, Xiluodu Water Electric Station, Xiangjiaba Water Electric Station, and Jinanqiao Water Electric Station in the upper reaches of the Yangtze River, Hongjiadu Water Electric Station and Goupitan Water Electric Station on the Wujiang River, Laxiwa Water Electric Station and Gongboxia Water Electric Station on the Yellow River, and Jinping Water Electric Station on the Yagong River, a large number of electric stations have been used, The YG-80 anchoring drilling rig has become the main model in the geotechnical anchoring engineering of domestic water electrical stations.

    Main features ● The drilling rig has strong drilling ability and a wide range of applications; Fast drilling speed, strong accident handling ability, and high drilling efficiency.
    ● The output shaft of the drilling rig's power head is equipped with a telescopic mechanism, which can effectively protect the drilling tools. The direction of the power head and orifice plate can be adjusted, allowing for direct drilling of upward holes, greatly increasing the range of drilling angles.
    ● The front of the drilling rig frame is equipped with up and down adjustable columns and huff, which can adjust the height of the mast, making the hole position quick and convenient during construction.
    ● The drilling rig orifice plate adopts an open and close core type, which can be quickly relocated and passed through a large-diameter down-hole impactor or a pipe following drilling tool.
    ● The drilling rig structure is split type, with good detachablity and convenient relocation and installation speed; And it can be remotely operated, completing porous construction in one relocation; The operating staff have a good working environment and low labor intensity.
    ● The hydraulic motor, pump, and quick connector of the drilling rig are made of international products, while other main components are selected from well-known domestic products to ensure stable, reliable, and long service life of the entire machine. The standardization and serialization of vulnerable parts in drilling rigs are high, and they have good interchangeability.
    ● The drilling rig is fully hydraulic driven and can achieve stepless speed regulation. It is easy to operate, easy to maintain, and has fewer vulnerable parts.
    ● Drilling rigs can be used with various drilling techniques, such as alloy rotary drilling, spiral drilling, down hole hammer drilling, and pipe following drilling.
