It is reported that，Xihoumen Rail-cum-Road Bridge is a sea-crossing bridge of Yongzhou-Zhoushan Railway and Yongzhou-Zhoushan expressway.，Connecting Jintang Island and Cezi Island in Zhoushan。Large scale of the project、High technical content，It is also affected by the change of water flow and tidal range.，Construction is extremely challenging。

Development of Super Engineering Traction Super Equipment，Sunward intelligenceSWDM1280 super Rotary Drilling Rig is specially designed for super engineering。The equipment has sufficient power.，For aperture⼤⼩Nope⼀、The depth of pile foundation varies.、The formation is complex and varied.⼯Condition，According to the actual load⾃Dynamic selection。It is equipped with⾃Assemble and disassemble the crawler chassis，Edge beam mining⽤Double-pin type⾃Movable inserting and pulling pin structures，Convenient disassembly and assembly，Convenient transition；At the same time，Adopt⾼Strength drill pipe，Bending and torsion resistance，Pass⼒Reliable。

“It can be drilled up to 7 meters in diameter.，The depth of the borehole is more than 170 meters.，Can meet the requirements of the rock-socketed pile with the ultra-large diameter deep hol。”Relevant personnel said，To ensure the smooth drilling of the first pile，Sunward Intelligence Carefully Deployed Expert Team，Provide technical support and safety training for pile foundation construction，Lay a solid foundation for successful spudding of the first pilot。

After the completion of the project，It will become a landmark project of China's high-speed railway cross-sea bridge.，It will also become the world's largest span highway and railway bridge and the world's widest cross-sea bridge.。At the same time，To improve the layout of the railway network，Promote the development of tourism along the line，Realize the integration of Ningbo and Zhoushan、Development in the same city，Accelerate the integration of Zhoushan and Ningbo“The Belt and Road”And the Yangtze River Economic Belt.。
