Recently，With Sunward IntelligenceSWDMThe 1280 super Rotary Drilling Rig successfully completed the graded drilling of pile 12 of Xihoumen Rail-cum-Road Bridge on Yongzhou Railway.，The pile foundation construction of the bridge was successfully completed.，Much earlier than the planned construction period，It marks a phased victory in the construction of the bridge.。
The bridge is flying fast“ Growth ”，It is inseparable from the strong technical support and scientific management of the construction party.，Can't live without us.“A great power weighs heavily”——Sunward intelligenceSWDMPowerful Power of 1280 Super Rotary Drilling Rig。It has performed the project with dauntless valor.，Fight again and again，Conquer again and again，Set new records again and again。
Go to war in the first battle！February 18, 2023， Super “Pile”Prepare to help build a super project，Sunward intelligenceSWDMDrilling of the First Pile of Xihoumen Rail-cum-Road Bridge with 1280 Super Rotary Drilling Rig，It marks the beginning of the foundation construction of the main tower pier of the bridge.，It also meansSWDM1280 Super Rotary Drilling Rig becomes“The world's largest rotary drilling rig in actual combat”。
The strength is beginning to show！April 19, 2023，Sunward Intelligence Successfully Held“The World's First Diamond Sunward IntelligenceSWDM1280 Super Rotary Drilling Rig Promotion Meeting”。Customer representatives of pile foundation industry from all over the country、 technical specialist 、Nearly 100 media reporters gathered in Ningbo, Zhejiang，The construction process of super rotary drilling rig was observed at the site of Xihoumen Rail-cum-Road Bridge project.，Everyone lamented the shock of the operation scene.。
Far ahead！June 10, 2023，With Sunward IntelligenceSWDM1280 Super Rotary Drilling Rig was used to drill the first pile of No.5 Pier 18 Anchor Pile of Xihoumen Rail-cum-Road Bridge，It marks that the construction of the main project of the bridge has changed from a single point to a whole line.，It also means that Sunward Intelligence has once again refreshed its own 4..Record of maximum borehole diameter of 5m，Tron“6.3m super-large diameter borehole”A new record。July 19, 2023，Sunward intelligenceSWDM1280 completed the world's largest diameter of 6.Drilling of the first pile of 3m rotary excavation pile，It has achieved a major breakthrough in super-large diameter drilling of rotary drilling rigs in China.。
The hard core shines the sword！August 17, 2023，After nearly 20 hours of continuous fighting,，Sunward intelligenceSWDM1280 Super Rotary Drilling Rig Completed the First Piece at No.5 Main Tower Pier“6.3m super-large diameter bored pile”Concrete pouring task，It marks that the main tower pier on the water of the project has entered the pile foundation construction stage in an all-round way.。
It is reported that，The first pile of this construction is No.15 pile of No.5 main tower pier.，Pile diameter 6.3 meters，Pile length 84m，Type is end bearing pile，AdoptSWDM1280 super rotary drilling rig graded pore-forming。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，And encounter several typhoons dure that drilling process.，It is also affected by the change of water flow and tidal range.，Construction is challenging。SWDM1280 Super Rotary Drilling Rig with Advanced Technology、Stable performance and reasonable construction method，Overcome“The wind is strong、The waves are high、Depth of water、The current is rapid、Bare rock”And other difficult problems。
This time, the first pile was bored and the underwater concrete pouring was successfully completed.，It not only provides reliable technical parameters for the construction of large diameter pile foundation,，Mark and make sample for the pile foundation construction of the project，It fills in the blank of construction technology of super-large diameter bored piles in deep water in China.，It's more revealing“Made in China”Construction of underground engineering equipment at a water depth of more than 60 meters in complex marine environment“Chinese power”。
Perfect ending！December 29, 2023，Sunward intelligenceSWDM1280 Super Rotary Drilling Rig Successfully Completed the Pile Foundation Construction of Xihoumen Rail-cum-Road Bridge。
It is reported that，Xihoumen Rail-cum-Road Bridge is 3118 meters long.，The bridge is a cable-stayed suspension cooperative system bridge with a main span of 1488 meters.，It is the largest highway and railway bridge in the world.，It is a control project of Yongzhou Railway under construction.，Connecting Jintang Island and Cezi Island in Zhoushan。After the completion of the project，To speed up the integration of Zhoushan and Ningbo“The Belt and Road”And the Yangtze River Economic Belt.。
July 2020，Sunward Intelligence and China Railway Bridge Engineering Bureau、Wuhan Lecheng Team aims at the construction environment of pile foundation of Xihoumen Rail-cum-Road Bridge、Pile type、Stratigraphic characteristics，Combine“Deep and medium passage”Construction experience of offshore pile foundation project，Start research on super rotary drilling rig and construction technology，Twelve expert technical workshops were held in the early part of the programme。January 2022，Under the leadership of He Qinghua, chief expert of Sunward Intelligence，The R & D team has conquered the construction stability of large-scale equipment.、Convenience of loading, unloading and transportation、Riveting and welding deformation of oversize parts、There are many technical difficulties in the machining accuracy of super-large machined parts.，SWDM1280 Super Rotary Drilling Rig officially rolled off the production line。
During the construction of Xihoumen Rail-cum-Road Bridge，Sunward intelligenceSWDM1280 Super Rotary Drilling Rig lasted less than 1 year，Successfully completed the construction of several ultra-large diameter deep-sea piles.，Among them, the deepest construction is 116 meters.，Fully demonstrated“A great power weighs heavily”The strength of。
Coming up，Sunward Intelligence will continue to play a leading role in innovation.，Development of traction equipment in engineering、Under the concept of realization of equipment support engineering，At the cutting edge of technology、Continuous efforts have been made in the research of advanced construction methods.，Build a complete set of solutions for underground engineering equipment，Contribute to the infrastructure of the motherland and even the world。
