The GK 200 Core Drilling Rig is a lightweight, efficient, multi-functional surface drill rig primarily designed for water wells, agricultural irrigation wells, geothermal air conditioner holes, and similar applications. This versatile drilling rig operates effectively across different strata and incorporates advanced hydraulic technology with a high-torque hydraulic rotary motor and large-diameter hydraulic cylinder propulsion.

• Oil pressure automatic feeding mechanism ensures high drilling efficiency
• Centralized handle design for convenient operation and enhanced safety
• Compact configuration with drilling rig, shifting base, and diesel engine all mounted on the same underframe
• Lightweight and modular design for easy transportation and mobility, suitable for both plains and mountainous terrain

After completing a well, pumping tests should be conducted to verify results. A large drawdown pumping test should typically last at least eight hours with stable water level measurements. The drilling site must maintain proper drainage, making rainy conditions unsuitable for operation.

Note: During excavation work, maintain proper slope angles (typically 1:1.5) based on soil characteristics. Ensure adequate distance between spoil piles and excavation openings. For wells with shaft wall water inflow, properly install and maintain inlet holes and filter layers according to design specifications.
