GZQ型潜水工程钻机,是一种电动回转式钻机,钻孔时主机连接钻头潜入孔中作业。它适用于淤泥质土、粘性土、砂性土、风化页岩及含有少量砾石的砂砾石土层等地层的钻进,广泛应用于工民建、港口、桥梁等基建基础工程作为灌注桩的成孔机械,亦可将数台主机组合成群钻,用作地下连续墙 GZQ-type submersible drilling rig is an electric rotary drilling rig. When drilling, the main engine is connected with the drill to dived into the hole. It is suitable for the drilling of silty clay, cohesive soil, sandy soil, weathered shale, and gravel soil layer containing a small amount of gravel. It is widely used as a cast-in-place pile in civil engineering construction, ports, bridges and other infrastructure foundation projects. Hole-forming machine can also combine several hosts into a group drill to use as underground continuous wall
