Build a solid rock foundation for the bridge
August 13，Good news came from the project site of the Xihoumen Rail-cum-Road Bridge on the Yongzhou Railway, which was constructed by China Railway Bridge Bureau.，By Sunward IntelligenceSWDMPile 15 of No.5 main pylon pier constructed by 1280 super Rotary Drilling Rig，After nearly 20 hours, about 2928m³Continuous placement of concrete，Finally successfully completed 6.Pouring of the first pile of the 3m diameter project，The Rotary Drilling Rig pore-forming pile-forming 6 is created.3 meter diameter world record，It has laid a solid foundation for the smooth development of follow-up projects.。
Pile 15 of the first pile of Pier 5 completed in this pouring，It belongs to the main pylon pier project of Xihoumen Rail-cum-Road Bridge on Yongzhou Railway.，Pile diameter 6.3 meters，Pile length 84m，Construction depth: 106m，Type is end bearing pile。The geological condition of the pile is hard.，Weakly weathered rhyolite up to 22.9 meters，Slightly weathered rhyolite up to 7.5 meters，Difficult to drill。The pile was built by Sunward Intelligence on July 5.SWDMFormal opening of 1280 rotary drilling rig，Five-stage drilling process is adopted.，The period will be 6.8m steel casing driven to 8m of bare rock surface of seabed，Drilling process equipment is stable and efficient，And took the lead in completing the first 6 of Pier 5 on July 19..3 m pile hole forming。
As a leading enterprise in the comprehensive field of Piling Machinery，Sunward Adhering to the Concept of Leading Innovation，Actively respond to the country、Market and customer needs，Developed all kinds of high-end、Specialization、Complete set of innovative products。Xihoumen Bridge has a large scale.、The bridge structure is novel、High technology content，It is a super cross-sea project that challenges the limits.，The site working condition has“The wind is strong、The waves are high、Depth of water、The current is rapid、Bare rock”Wait for the situation。It is the super project of Xihoumen Rail-cum-Road Bridge on Yongzhou Railway.，Traction of Sunward IntelligenceSWDMDevelopment of 1280 Super Rotary Drilling Rig。
SWDMThe maximum hole diameter of 1280 rotary drilling rig can reach 7 meters.，The maximum hole depth can reach 176 meters.，With the powerful leading R & D and innovation capability of Sunward Intelligence,，Aim at that stability and drilling technology of ultra-deep large-diameter hard rock drill hol、Convenient disassembly and assembly of large equipment and operation reliability, etc.，Braking force enhancement technology of large inertia slewing platform is developed、Five-key bar high-strength large-diameter drill rod、Large-diameter large-length single-layer rope arranging roller、More than ten innovative technologies such as symmetrical power bolt modular chassis。With these innovative technologies，SWDMThe 1280 rotary drilling rig is in the construction of the No.6 pier before the Xihoumen Rail-cum-Road Bridge and the No.5 main tower pier now.，Stable performance、Reliable、Efficient，It has been fully affirmed by the conTractor China Railway Bridge Bureau and the construction party Wuhan Lecheng.。
In recent years，Piling Machinery industry is in a period of adjustment，However, there is no off-season for R & D.，Sunward Intelligence always adheres to the concept of leading innovation.，Increase investment in innovation and R & D，A super static Pile Driver is developed.、Super Pile Frame、Super rotary drilling rig and other super equipment，And in the deep and middle channels.、Yanji Yangtze River Bridge、Applied in super projects at home and abroad such as China-Thailand Railway，Leading the upgrading and development of the industry。
Future，Sunward Intelligence will further increase R & D investment，Development of traction equipment in engineering、Under the concept of realization of equipment support engineering，Special stratum for foundation construction of driving pile、Special environment、Special pile type scene requirement，Through engineering、Collaborative innovation of construction method and equipment，Continuously leading the Piling Machinery industry to complete sets、Develop in the direction of specialization。
