Ⅰ. Application Of Hydraulic Water Well Drilling Rig
Hydraulic water well drilling rig is mainly suitable for the construction of water well drilling rigs and geothermal hole construction. It is also suitable for the construction of large-aperture vertical holes or unloading holes in geotechnical engineering such as hydropower stations, railways, highways, and urban foundations; grouting reinforcement holes; small foundations pile hole; micro-pile, etc.
Hydraulic water well drilling rig uses a variety of techniques, such as conventional down-the-hole hammer drilling, long auger drilling, mud circulation drilling, follow-pipe drilling, roller cone drilling, hydraulic hammer drilling, etc.
Ⅱ. What Are The Characteristics And Advantages Of The Hydraulic Water Well Drilling Rig?
1. The main shaft of the power head of the hydraulic water well drilling rig has a floating function, which effectively protects the drill pipe thread; the casing power head doubles as a pipe screwing machine, which can realize the mechanization of drilling tool unloading;
2. The hydraulic motor, operating valve, and oil pump of the hydraulic water well drilling rig adopt international famous brand products, and other components are selected from high-quality products, so that the performance of the whole machine is stable, reliable and long-lived;
3. The hydraulic water well drilling rig is a dual-power head drilling rig, and no active drill pipe is required; the extended 7m stroke greatly reduces the number of guide rods, improves the drilling efficiency, and reduces the accident rate in the hole; and can achieve full stroke compression or decompression drilling.
