Integral drill rod

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.
