  • Concealed (inclined) well reverse rig construction
    Concealed (inclined) well reverse rig construction
    Jining Zhuoli dark well (inclined) well reverse rig construction uses low-profile reverse rig construction, which can complete the construction of holes with a diameter of 1m, 1.2m, 1.4m, 1.6m. Features of low-profile reverse rigs: 1. In the slewing system, two parallel low-speed high-torque hydraulic motors are selected, which simplifies the design of the reduction box and also obtains two different speeds and torques. 2. Adopt
  • Pipeline Reverse Drilling Rig Construction
    Pipeline Reverse Drilling Rig Construction
    Jining Zhuoli pipeline backhole drilling rig construction uses low-profile backhole drilling rig construction, which can complete the construction of holes with diameters of 1m, 1.2m, 1.4m, and 1.6m. Features of low-profile reverse rigs: 1. In the slewing system, two parallel low-speed high-torque hydraulic motors are selected, which simplifies the design of the reduction box and also obtains two different speeds and torques. 2.Adopt international
  • Cable hole reverse rig construction
    Cable hole reverse rig construction
    Zhuoli Cable Reverse Drilling Rig construction uses low-profile reverse well drilling rig construction, which can complete the construction of hole diameters of 1m, 1.2m, 1.4m, and 1.6m. The construction of cable hole reverse rigs is mainly divided into four stages: 1) The reverse rig preparation stage. After having the corresponding wind, water and electricity conditions, install the back-drilling rig on the pre-cast concrete foundation and connect the hydraulic system pipes of all parts.
  • Construction of coal chute hole reverse rig
    Construction of coal chute hole reverse rig
    Zhuoli slip coal hole reverse well drilling rig construction adopts low-profile reverse well drilling rig construction, which can complete the hole construction diameter of 1m, 1.2m, 1.4m, 1.6m. The principle of the construction of the reverse well drilling rig The reverse well drilling rig guide method mainly uses the reverse drilling rig drilling principle: the electric motor drives the hydraulic motor, and uses hydraulic power to transmit torque to the drilling tool system, which drives the drilling tool to rotate and lifts up and down.
  • Ventilation hole reverse rig construction
    Ventilation hole reverse rig construction
    The construction of Zhuoli ventilating hole reverse boring rig adopts low-profile reverse boring rig construction, which can complete the work construction with hole diameters of 1m, 1.2m, 1.4m and 1.6m. Key points of precision control of reverse rig construction in complex geology In vertical and inclined shaft construction, pilot hole precision control is the key to the construction of reverse rig guide. The excavation section of Shuibuya Hydropower Station's traffic shafts and bus shafts is large.
  • Underground coal bunker reverse rig construction
    Underground coal bunker reverse rig construction
    Jining Zhuoli underground coal silo reverse well drilling rig construction adopts low-profile reverse well drilling rig construction, which can complete the operation construction with hole diameters of 1m, 1.2m, 1.4m and 1.6m. Jining Zhuoli is a large-scale enterprise specializing in the construction of low-profile reverse rigs in coal mines. The company is mainly engaged in the construction of underground coal silo reverse rigs, concealed (inclined) well reverse rigs, pipeline hole reverse rigs, cable holes. Anti well
