Close to the vast East China Sea Large and small islands dot the landscape.

“The world's first diamond”XugongXR1600E

The first charge  Concentrate on drilling“Rock”!

Help one“The best in the world”Rise from the ground

Ending the History of Zhoushan Islands without Railway

XugongXR1600EThe rotary drilling rig participated in the construction of the Xihoumen Highway and Railway Bridge.，The project is a common cross-sea bridge for Yongzhou Railway and Yongzhou Expressway to cross Xihoumen Waterway.，The main span is 1488 meters，YesCable-stayed bridge with the largest span under construction in the world—Cable-suspended cooperative system bridge，Yeah, tooAt present, it is the largest highway and railway bridge in China.。

Such a large span，Moreover, the wind is strong and the waves are high in the bridge site area，The water is deep and swift.，There are also broken bare rock layers under the water.……XugongXR1600EThe main tower foundation on the side of Cezi Island of the bridge participated in the construction（Foundation of Pier 5）Water depth up to 60 meters，The maximum water depth of the cross-sea bridges built in China is only 40 meters.，This is a great challenge for the construction of the bridge foundation.。

For this reason，Adopted by the builder18 diameters6.3 meters、84-meter-long super-large diameter bored pile，This is also the largest diameter bored pile foundation of bridge in the world.。

XugongXR1600ERotary drilling rigThe maximum drilling depth can reach 190 meters.，The maximum drilling diameter can be up to 7.5 meters，It is a super high-rise building、High-speed railway、River-crossing and sea-crossing bridge、The preferred model for offshore wind power and other super-large pile foundation projects。

In order to facilitate transportation，XR1600EAdoptIndustry's first split drive station，Working performance of the whole machine、Construction efficiency、Function expansion、Structural strength、Security protection、Service life、Routine maintenance、The appearance of the whole machine has been upgraded in an all-round way.，With more than 20 invention patents，It represents the new level of global pile foundation construction equipment.。

Under the specially equipped drill pipe，XR1600EThe rotary drilling rig is fully competent for the ultra-large diameter 6 of water seepage bare rock in the complex marine environment..A 3-meter challenge，The construction of the pile foundation is proceeding as planned.。

It is understood that，After the completion of Xihoumen Highway and Railway Project，It will directly fill the gap of no railway in Zhoushan.，Railway in the middle of the bridge，The design speed is 250km/h，On both sides are expressways，The design speed is 100km/h，Zhejiang Province will be completed“Provincial 1-hour high-speed rail traffic circle”And“The city is connected to the high-speed railway”The last short board，To realize the 30-minute railway access from Ningbo to Zhoushan。
