June 30, 2024，The Shenzhen-Medium Passage, a Super Project in Guangdong-Hong Kong-Macao Greater Bay Area, which attracts worldwide attention，It was officially put into trial operation.。The journey from Shenzhen to Zhongshan has been shortened from about 2 hours to 30 minutes.。

As the world's first episode“Bridge、Island、Tunnel、Underwater communication”It is a cross-sea cluster project.，The Shenzhen-Medium Passage has achieved many technological innovations.，Once again, China's infrastructure business card has been polished.。As the Pearl River Estuary“A”One of the keys to the skeleton of the glyph traffic network“Horizontal”，The Shenzhen-Medium Passage with a total length of about 24 kilometers crosses the Lingdingyang Sea.，Let the east and west banks of the Pearl River Estuary“Shenzhen, Dongguan and Huizhou”And“Pearl River”The two urban agglomerations have been directly connected across the sea.。Its completion and opening will completely change the overall road network pattern of the Pearl River Estuary.，It is of great significance to the economic and social development of Guangdong-Hong Kong-Macao Greater Bay Area.。

 

The Shenzhen-Zhongshan Bridge was officially opened to traffic 

The successful completion of this world-class cross-sea cluster project，It is inseparable from Xugong.、Trinity、Zoomlion、Sunward intelligence、Bao'e、Fogler、Humvee、Deep participation and outstanding contribution of many construction machinery brands such as Zhejiang Zhuma。

As a key force in construction，XCMG with its rotary drilling rig、Concrete pump truck、Oscillating rollers and other equipment drill holes on the seabed.、Concrete pumping and pavement compaction play an important role.。

Sany uses concrete machinery.、Full participation of lifting machinery and excavation machinery，In particular to a steel bridge deck epoxy pavement engineering.，Its efficient and accurate asphalt mixture transportation device and roller equipment escort the construction.。

Zoomlion、Enterprises such as Sunward Intelligence have also contributed a lot to the construction of key nodes such as the West Artificial Island.。The tower crane equipment of Zoomlion is stable and reliable，After many typhoons, it still stands firm.；Sunward Intelligence provides super-large equipment with excellent performance.，It is supported by professional construction method and after-sales service.，It provides all-round guarantee for construction.。

In addition，Double-wheel slot milling machine of Bao'e、Fogler's paver、Hummer's Road Roller and Zhejiang Zhuma'sMAXThe 60 high-speed sweeper also played an important role in the construction of the Shenzhen-Medium Passage.。Widespread use of these devices and technologies，It not only improves the construction efficiency,，It also ensures the high standard of project quality.、Strict requirements。

Xugong Team Fighting World Super Project“Deep and medium passage”

Submarine drilling construction，It is the home of XCMG rotary drilling rig.。The maximum wind speed at sea can reach 40m/s，Hole depth during construction: 85m、Diameter 3m、Enter 28mGranite，Xugong rotary drill said：“Look at me！”

XugongXR550DThe power head has normal mode and rock entry mode.，Respectively for soil and rock operations，And has an automatic rotation function.，The rotating speed is continuously adjustable during construction.。During construction，XCMG even adopts the new construction method of rotary drilling rig.，Operation efficiency is greatly improved，Highlight the heavy weapon of a big country“Depth”。

The pouring link of the support beam in the weir construction section of the east artificial island of the Shenzhen-Medium Passage，XugongV7 series concrete pump truck works day and night，Key breakthroughs have been made in construction。XugongV7 series concrete pump truck completes various pumping tasks efficiently，It has won great praise from the contractor.。

In the pavement of the tunnel，XCMG Road Machinery Plays the Prelude to Victory。Vast and mighty，XugongXD135TOSIVOscillating roller pulls open the last key process of the tunnel pavement works of the project。High temperature and high humidity、Poor ventilation、Ultra-wide and ultra-long，In a relatively closed space of nearly 6 kilometers in the cave.，XCMG Road Machinery Completes New Paving Challenges。

XugongXD135TOSIVThe oscillating roller becomes“Deep and medium passage”The backbone of key construction links。

XugongXGC55 crawler cranes also lead the lifting corps.，It was staged in the construction of the Shenzhen-Medium Passage.“Hoisting contest”。

Sanyi Red Polishes the Brand Made in China

Sany is one of the main construction machinery brands of Shenzhen-Medium Passage Project.，More than 20 SANY crawler cranes、Pump truck、Mixer trucks are stationed all the year round。The tower of Shenzhong Bridge is 270 meters high.，Steel hanging box is the pile foundation of the main tower.“Nut in the sea”，The height of the steel hanging box is 17.6 meters、Outside diameter 41.1 meter，Weight 1800 tons，More than seven Airbus.AA total weight of 380。July 2019，Resultant force of multiple Trinity crawler crane，Will this one“A giant of steel”Take root in Lingdingyang。

March 2020，The project has progressed to the most difficult stage of bridge foundation construction.，Pouring of cable tower bearing platform“The world's king of pumps”Go！The construction party decides，All of them are contracted by Sany Equipment.。

Under construction，The performance of Sany pump truck is perfect.，In succession、There was no failure in the high-intensity operation.，Its construction time is even 10% shorter than that of the scheme％，It has created a record of single concrete pouring volume for the whole project.。
