This is the Sunward Intelligent SWDM450V rotary drilling rig that undertakes the pile foundation task at the Xiangfu Double-Line Extra Large Bridge of Guinan High-speed Railway. Since the construction of the site for one month, 450V has only completed 3 piles, but it has received repeated praise from the customer, Mr. Zhu.

The Guinan High-speed Railway, connecting Guiyang and Nanning, is one of the "eight vertical and eight horizontal" high-speed railway main passages in my country's railway network planning. Among them, the Xiangfu Double-Line Bridge in Duan County, Hechi, Guangxi, is a key project part of the entire line. Constructed by China Railway 11th Bureau Group. The bridge pile depth is designed to be 93 meters, and the poor geological conditions of the lava in the area greatly increase the difficulty of pile foundation construction!

Mr. Zhu, who undertook this construction task, knew the difficulty of the project well. After many visits in the early stage, he had an in-depth understanding of the industry bridge pile foundation project, and finally found a rotary drilling rig that meets the requirements-Sunward Intelligent SWDM450V super-large multifunctional rotary drilling rig. Mr. Zhu said, “During my visit, I learned that Sunward Intelligent, as a leading enterprise in the field of underground engineering and an expert in underground complete solutions, has more than 20 years of experience and technology accumulation. It is located in the Shenzhen Middle Channel of Guangdong and the Feiyun River in Wenzhou. A series of super projects such as the Sea Crossing Bridge, the Sanmenxia Mongolia-China Railway Crossing the Yellow River Bridge, and the Huaisho Heng High-speed Railway Zijiang Bridge, have successful cases of super-large and super-deep pile foundation construction. I believe that the selection of Shanhe must be right!"

After the equipment arrived at the construction site, the construction team led by Sunward Intelligent professional operator and Mr. Zhu immediately went into the intense construction. In early May, after overcoming 6 to 7 layers of karst caves and super-hard limestone oblique rock, Sunward’s intelligent SWDM450V rotary drilling rig successfully drove the first drilling of ultra-deep piles, which also marked the most difficult piece of “hard rock” on the entire Guinan high-speed rail line. "Has been breached! This super equipment, overcoming huge construction difficulties in the next month, drilled 91 to 96 meters and completed the construction of 3 piles, which also fully guaranteed the project to be completed on schedule!

Customer Mr. Zhu gave us feedback, “I have used many brands of equipment, but Sunward’s rotary drilling capability is the strongest, the most efficient, and the hole-forming effect is very good! Sunward’s intelligent rotary drilling rig deserves its name.” Mr. Zhu Said that after the drawings for the next tender section are released, they will work closely with Sunward to purchase multiple Sunward intelligent rotary drilling rigs!Editor/Baohongying
