The DMiningwell RD400 water well drilling rig is a remarkable piece of machinery. It is a multifunctional hydraulic drilling equipment designed to excel in the toughest conditions, such as the mountainous areas with harsh environments and complex rock formations for water extraction. The entire vehicle's movements are powered by hydraulic systems, ensuring low labor intensity. With a reasonable vehicle size design, large front and rear outrigger spacing, and high stroke, it can be self-loaded and unloaded without the need for hoisting. The operation is made simple with all control handles integrated into the console, providing a clear interface for real-time monitoring of the rig's operation. The electrical system features integrated wiring with high waterproof rating, and the enclosed outrigger design prevents sediment backflow. Its unique features like the chain wheel with cylindrical roller bearings and skeleton oil seals reduce maintenance costs, and the engine air intake system with 2 - 3 times of filtration strictly protects the engine. The rig also allows for easy maintenance of the engine and hydraulic system through the lifting of the engine compartment by the sliding frame. The smooth and reasonable layout of the hydraulic pipeline extends the service life of the hydraulic hose. The special wear-resistant angle steel structure of the power head's propulsion and lifting track enables adjustable clearance and stable drilling with low resistance. Built with renowned domestic and international core components, the DMiningwell RD400 ensures stable performance and is a top choice for drilling operations.

The cofferdam project is a large-aperture pile hole construction plan. 1000mm and 1200mm diameter casings need to be inserted into the rock formation for 5-6 meters, the total depth of the pile holes is 25-30 meters, 300 piles with a diameter of 1200mm, and 280 piles with a diameter of 1000mm. This solution is expected to allow the port to obtain a load capacity of 500,000 tons, thereby increasing the throughput of the Chulai port.
On January 31, the project’s first casing pipe pile test pile was successful. Under the condition of rock hardness of 100-150Mpa, 6 meters into the rock was completed within 4 hours, laying a solid foundation for the second phase expansion of Chulai Port.
