Integrated DTH drilling rig D470A

A machinery exhibition with the theme of "Machinery and Technology" was held in Hangzhou, Zhejiang from September 25 to 27, 2024, and Zhejiang Mining Supply Chain Management Co., Ltd. became the highlight of the exhibition. Its booth at the exhibition attracted a lot of attention. The mechanical products displayed were integrated with scientific and technological achievements. From drilling equipment to power transmission devices, the company's technical strength was fully demonstrated. The professional team explained the products in detail. In addition, the company also communicates and interacts with all parties through various forms to enhance its visibility and lay the foundation for cooperation. This exhibition demonstrates its strength and delivers innovative development signals, which is expected to promote industry progress.

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.
