The other day，With Sunward Intelligent Super Rotary Drilling RigSWDM1280 Drilling of the first pile of Pier 5 of Xihoumen Rail-cum-Road Bridge on Yongzhou Railway，It marks an important stage progress in the construction of the main pier foundation of the world's largest span highway and railway bridge.。

Timeline

In January this year，Sunward Intelligent Super Rotary Drilling RigSWDM1280 Xihoumen Rail-cum-Road Bridge。

February ，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，Spud at the first pile of Pier 6，Become the world's largest rotary drilling rig in actual combat，Breaking the Sunward IntelligenceSWDM1000 records of rotary drilling rig。

At present，After the successful completion of the pile foundation construction of Pier 6，The equipment was successfully transferred to Pier 5.，Continue to escort the project construction。

It is understood that，Pier No.5 of Xihoumen Rail-cum-Road Bridge Project is the main pylon pier，The construction area is windy and rough.，The geology is complex，And the water depth is more than 60 meters.，It is difficult to locate the platform and drive the supporting piles.。Yongzhou Railway Project Department of China Railway Bridge Engineering Group Co., Ltd.，An offshore floating steel truss drilling platform is developed，Its area is equivalent to the size of 31standard basketball courts.。

△Sunward Intelligent Super Rotary Drilling Rig was previously constructed at Pier 6.。

At the same time，China Railway Major Bridge Engineering Group Co., Ltd. and Sunward Intelligence、Construction Environment of Pile Foundation of Xihoumen Rail-cum-Road Bridge in Lecheng, Wuhan、Pile type、Stratigraphic characteristics，Used up to 6 dia..3 m super-large diameter engineering pile，Its diameter is the largest in the world bridge engineering pile at present.。Sunward Intelligent Super Rotary ExcavationSWDM1280 First drilling at Pier 5，It means that it has once again refreshed the previous record of 4..Record of maximum borehole diameter of 5m，Gen 6.A new record of 3 m diameter borehole。

The Xihoumen Rail-cum-Road Bridge has been progressing smoothly since it won the bid in October last year.，The construction party plans to complete the bored pile construction of the main tower pier by the end of this year.，It is expected that the civil works of the whole bridge will be completed by the end of April 2028.。As an important bid section of Yongzhou Railway Project，Xihoumen Rail-cum-Road Bridge will speed up the integration of Zhoushan and Ningbo“The Belt and Road”And the Yangtze River Economic Belt.。

Sunward Intelligence is the leading enterprise of piling machinery.，Adhere to“Pilot innovation”Idea，For a long time, it has insisted on the development of engineering traction equipment.，Realization of Engineering Supported by Equipment，In the future, we will do our best to help build it.“Yongzhou Railway Project”And other major projects，Lead the industry development。
