Focus on XCMG twice“The world's first diamond”Participate in the construction

Construction of Xihoumen Rail-cum-Road Bridge on Yongzhou-Zhoushan Railway

The world's largest highway and railway cross-sea bridge——Xihoumen Rail-cum-Road Bridge，The Xihoumen Waterway in Zhoushan, Zhejiang，The water here is deep and swift.，Poor environment and construction conditions，Currently under construction。 

In the past, the maximum water depth of the cross-sea bridge was only 40 meters.，The water depth of Pier 5 of Xihoumen Rail-cum-Road Bridge is 60 meters.。For this reason，Designed with 18 PCs of 6 dia..3 m bored pile，This is the largest diameter bored pile foundation for bridges in the world.。 

In the CCTV lens，XugongXR1600ETowering drilling platform on the river surface，Burrowing into the rocks beneath the seabed.，Spud diameter 6.3m pile foundation。In the gale、Rapids、Bare rock、In the complex marine environment of deep water.，Construction of super-large diameter bored pile，Yes, even with“The world's first diamond”It's calledXR1600EIt's not easy for me。 

XugongXR1600EMulti-gear mode of rotary drilling rig relying on power head、Drill pipe visualization、Dual power system and many other intelligent technologies，Comfortable and smooth driving experience，Not afraid of complex marine environment“Deep water、Bare rock、6.3mExtra large diameter”Drilling challenge，Aggressive drilling。

XR1600EIn less than 3 days，Drilling depth near 90m，Superior efficiency，As required by the Construction Project Department，It took the lead in completing the drilling construction for lowering the 8 m diameter casing.，“The hardest bone in the project has been gnawed.”，It lays a good foundation for the subsequent super-large diameter pile pore-forming construction。

XugongXR1600ERotary drilling rig has attracted great attention in the industry since it came out.，ItsMaximum drilling diameter 7.5m，Maximum drilling depth 190m，Be known as“The world's first diamond”。Specifically for 6mAbove extra large diameter，100mThe above super-deep piles，Can satisfy 100MPaConstruction of the above super-hard pile foundation，Its appearance marks various complex working conditions in the field of bridge and tunnel construction worldwide.，It can deal with it easily.。

Other than that，XR1600EModular design is adopted，YesAt present, it is the first rotary drilling rig in the world that can be transported in all parts.，After disassembly，Each module does not exceed 50 tons.，Construction sites in mountainous areas or even at higher altitudes，It is easy to enter.。

Rock hard pile large flow turbulence，Rotary drilling and cutting are in full swing。Since 2012，XCMG has successfully developed 60 types of rotary drilling rigs.，Participated in the construction of nearly 20,000 bridges，The length of the bridge and tunnel is over 100,000 kilometers.，Successfully solved the Hong Kong-Zhuhai-Macao Bridge、Deep and medium passage、Extra large diameter of river-crossing and sea-crossing bridges such as the Sichuan-Tibet Railway、Difficult construction of super deep pile。XCMG is committed to using sophisticated equipment to achieve“A bridge flies north and south.，The natural moat becomes a thoroughfare”A beautiful blueprint。
