Overview of Shandong Bangxin’s Water Well Drilling Rig Designed for Cobble Formations

Applicable Scenarios
These drilling rigs are suitable for household drinking water wells, farmland irrigation wells, construction site dewatering wells, and geothermal heat pump air – conditioning wells.

Advantages
Track Power: They adopt a crawler chassis, which is convenient for movement and can adapt to various terrains. The chassis is equipped with hydraulic outriggers to reduce vibrations during construction and enhance stability.
Applicable Geological Conditions
They are suitable for drilling in soil layers, quicksand layers, and a small amount of rock – soil layers. They are mainly used for drilling civil drinking water wells, geothermal heat pump air – conditioning wells, engineering dewatering wells, drought – resistant wells, and industrial wells.

Features
Easy Startup: The diesel engine is equipped with an electric starter, reducing the labor intensity of operators.
Sustainable Operation: Based on the hydraulic working principle and equipped with a radiator, the rig can work continuously.
Flexible Power Head: It is equipped with a high – power hydraulic motor, allowing the power head to rotate forward and backward.
Convenient Drill Frame Operation: The drill frame is equipped with hydraulic cylinders, and the hydraulic lifting and lowering can be achieved by operating the handle.
Efficient Slag Discharge and Easy Movement: It comes with a water pump, with a reasonable structure and compact layout, ensuring good slag – discharging effects. It is also equipped with a drawbar and wheel – type traveling mechanism for easy movement. Additionally, it has screw – support outriggers for leveling the rig.
Shandong Binzhou BZC150DF Vehicle – Mounted Reverse – Circulation Well Drilling Rig
Applicable Scenarios
This rig is suitable for drilling various industrial and agricultural water wells, as well as for construction of building foundations, bridge foundations, oilfield casings, high – voltage power line poles, wind turbine base piles, port wharves, and dam foundations in soil, sand, and gravel layers.

Features
Powerful: It uses a vehicle engine as power, with a power of 132kW.
Reverse – Circulation Drilling: It is equipped with a 6BS sand – gravel pump reverse – circulation pump set. Using mud as the flushing fluid, reverse – circulation drilling can be achieved by switching the mud circulation direction. A CB – E532 vacuum pump water – priming system is added to facilitate water priming for the 6BS sand – gravel pump.
High Flexibility: A full – vehicle hydraulic system is added. The power head is hydraulically lifted, the tower is hydraulically raised and lowered, and the four outriggers are hydraulically controlled. Two rear outriggers can extend horizontally. The four outriggers can be operated either simultaneously or individually, facilitating quick leveling of the rig.
Technical Parameters
Power Head Rotation Speed: 11 – 22r/min.
Power Head Torque: 15 — 7.5kN.m.
Jujang Group JDL – 400 Water – Air Dual – Purpose Drilling Rig
Applicable Scenarios
This rig is suitable for all kinds of strata. It especially solves the problems of difficult air – drilling with air down – la – hole hammers in soil layers and low construction efficiency of water – drilling with mud in hard rock layers, gravel, and pebble layers.

Features
Advanced Gearbox: It adopts an AMT automatic – manual integrated gearbox.
Unique Mechanism and Power Head: It uses a long – stroke speed – doubling mechanism and a mechanical power head.
Efficient Hydraulic System: It is powered by a double – pump oil supply system. The hydraulic system uses flow – splitting and merging technology. The main shaft is mechanically driven, and some functional interfaces are reserved in the hydraulic control system.
Technical Parameters
Working Strata: Loose soil layers and bedrock (hardness F6 – 20).
Drilling Method: Top – drive mechanical rotation with hydraulic propulsion, using mud drilling or pneumatic down – la – hole hammer drilling.
Jining Tongzhao Machinery TZ – 100 Slope Crawler – Type Anchoring Drilling Rig
Applicable Scenarios
This rig is suitable for construction, water conservancy, exploration, deep – foundation pit support, slope reinforcement, and other projects. It is especially suitable for foundation pit anchor holes, construction site drilling, and can also drill in pebble layers.

Features
High – Efficiency and Energy – Saving: The drill arm can reach a maximum stroke height of 5.5 meters, with a daily drilling efficiency of up to 1500 meters, greatly saving labor costs.
Flexible Operation: The main arm can pitch within a 90° range, and the drill frame can swing within a 180° range. The unique telescopic arm and rotating arm design enable the rig to perform multi – layer anchoring operations within a 6 – meter height range. The main frame can rotate 360°, enabling dense – hole drilling within a certain range.
Strong Adaptability: It can not only drill quickly in general rock layers but also achieve rapid drilling in gravel and pebble layers. It has strong adaptability to different geological conditions and is suitable for high – density drilling operations.
