High-Efficiency Grinding Disc Drilling Rig for Large-Diameter Water Well Projects
Product Introduction of 1000 Rotary Disc Drilling
The grinding disc drilling rig is a type of water well drilling equipment with a rotary disc (grinding disc) as the core power output component. It drives the drill rod and drill bit to rotate and break the formation through the rotary disc, and carries rock debris with the help of mud positive circulation flushing. At the same time, it relies on the hoisting system to achieve drilling tool lifting, depressurization drilling and other operations. The power can be selected from diesel/electric motors, and the structure is mostly loose. It can also be customized as a crawler/vehicle mounted self-propelled type.

The advantages are as follows:
1. Outstanding large-diameter drilling capabilityAs a core advantage, the maximum drilling diameter of the grinding disc drilling rig can reach 1.8-3m, far exceeding conventional water well drilling rigs. It can meet the needs of large aperture operations such as high flow water wells (such as farmland irrigation, centralized water supply), engineering pile holes, etc., and the single well water output is more stable.
2. Multi layer adaptation, strong adaptability to working conditions
Relying on the strong torque output driven by the rotary table and the mud positive circulation wall protection technology, it can cope with complex formations such as Quaternary soil layers, soft rocks, and gravel layers, and is not prone to hole wall collapse problems. It can operate stably in different terrains such as mountains, plains, and hills.
3. Mature structure, low threshold for operation and maintenance
Adopting a classic mechanical transmission structure, the core components (turntable, winch, drill rod) have strong universality, simple operation process, and ordinary operators can get started after short-term training; Post maintenance does not require specialized equipment, the cost of purchasing accessories is low, and troubleshooting is convenient.
4. Flexible power, adaptable to multiple work environments
Supporting dual power switching between diesel and electric, diesel power is suitable for remote outdoor construction sites without grid coverage, while electric power meets the energy-saving and low-noise needs of power supply scenarios such as factory areas and villages, with more controllable usage costs.
5. High cost-effectiveness, one machine with multiple uses
Compared to high-end equipment such as rotary drilling rigs, the procurement cost is lower; At the same time, it has functions such as drilling, hydrogeological exploration, and small-scale engineering pile foundation drilling. One equipment can cover multiple types of operational needs, improve equipment utilization, and reduce comprehensive investment costs.
6. Customizable and easy to transition
The basic model is a bulk structure, which is easy to disassemble and transport; It is also possible to customize tracked or vehicle mounted chassis according to needs, enabling self movement and transfer, reducing the cost and time of lifting and trailer transportation.
Scope of adaptation:
1. Construction of agricultural irrigation wells
This is its most core application scenario. Large diameter drilling (up to 1.8-3m) can ensure high flow of water from a single well, meet the irrigation needs of large-scale crops such as farmland, orchards, and greenhouses, and adapt to agricultural water conservancy construction in various terrains such as plains and hills.
2. Centralized water supply project for villages and towns/factory areas
For the living and production water needs of rural settlements and small and medium-sized factories, medium to deep wells (300-1000m) can be drilled, with stable water output that can meet the requirements of large-scale water supply, and equipment and construction costs are much lower than high-end drilling equipment.
3. Hydrogeological exploration drilling
Used for hydrological survey operations in geological exploration units, it can drill rock cores, detect groundwater levels and water quality, provide basic geological data for water conservancy planning and engineering construction, and adapt to complex strata such as soil layers, soft rocks, and gravel layers.
4. Construction of small engineering pile foundation/dewatering hole
It can undertake pile foundation drilling for small rural bridges and low rise buildings, as well as auxiliary engineering operations such as foundation pit dewatering holes and ventilation holes, replacing the functions of some rotary drilling machines and reducing the construction cost of small projects.
