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.
D miningwell is a professional enterprise engaged in the research, production and sales of drilling tools.
