XCMG Rotary Drilling Rig for China's Bridge and Tunnel Industry in the Past 10 Years

Refreshed record

Ten Years of the New Era，Open the way in every mountain，Bridge in water“Longest、Highest、Max”The record is constantly written into the history of bridge and tunnel construction in the world, and in the process of super bridge and tunnel construction.、Super deep、Pile foundation construction in superhard stratum is a key step to lay a good foundation.

 

Xugong rotary drilling rig is often the first large equipment to enter the site, which has laid a solid foundation for each super project to break the ground.“China Bridge、China Tunnel”Constantly refreshing the world's understanding.

 

“Three, two, one，Spud……”In Xinyang City, Henan Province，The newly started Mingji Expressway is under intensive construction.，It is surrounded by mountains on three sides.，Residents expect the construction of the bridge to open up a road to prosperity.。

Construction of pile foundations on granite with a hardness of up to 180 MPa，Its strength is 6 times that of ordinary concrete.。

 

Compared with the beginning of the project，It took 46 days to percussively drill a two-meter diameter core.，Two hammers were undone.，To become a pile.。After mobilization of large-tonnage rotary drilling rig of XCMG，NowFour piles can be driven in a month.，The speed of hole formation is 6 to 7 times faster than before.，Efficiency has increased several times.。

 

However, ten years ago, the scene of efficient construction of rotary drilling rig was not common.。

Ten years ago，The market share of domestic rotary drilling rigs in China is less than 10%，Impact hammers are mainly used in domestic infrastructure construction.、Reverse circulation drilling rig，A large amount of mud is needed during construction.，Not only pollute the environment，The construction efficiency is also at least four to five times lower than that of the rotary drilling rig.。Facing hard rock，They can only dig holes by hand.。And at the time，Open the way and build the bridge，It has become an urgent need for China's economic development.。

 

Zhang Zhonghai, Chief Designer of XCMG Rotary Drilling Rig Project：

The Yangtze River、Some offshore construction projects such as the Yellow River，A large number of bridges need to be built.。The key technology is that you can't buy it.、I can't get it，We must take the road of independent research and development.。

For ten years，With the high-speed railway、Urban viaduct、The appearance of the cross-sea bridge，New requirements are put forward for the construction capacity of rotary drilling rig.，XCMG rotary drilling rig has also been realized.From small tonnage to large tonnage、Super large tonnageA butterfly change。

  

In July this year，“The world's first diamond”XR1600EGet off the line in XCMG Glory，This rotary drilling rigMaximum drilling diameter 7.5 meters，Maximum drilling depth 190m，Its appearance marks various complex working conditions in the field of bridge and tunnel construction worldwide.，It can deal with it easily.。

At present，China's infrastructure construction has entered a new stage of high-quality development.，In order to allow the rotary drilling rig to reach remote areas,，Adapt to the sea bridge、Offshore wind power、Superhard formation、High altitude and other extreme working conditions，This requires“The world's first diamond”Not only to be able to cut through the thorns.，And be able to cross mountains。

 

Sun Yu, designer of rotary drilling rig of XCMG：

XR1600EIt is the first rotary drilling rig in the world that can be transported in all parts.，Each module does not exceed 50 tons after disassembly.，Many steep construction sites in mountainous areas and even at high altitudes，XugongXR1600EIt's easy to enter.。

 

Since 2012，XCMG has successfully developed 45 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、Construction problem of super deep pile。

 

So far，More than 10,000 XCMG rotary drilling rigs are working on the front line of bridge and tunnel construction in more than 80 countries around the world.，On the Hanyun Industrial Internet Platform independently built by XCMG，The operation of all equipment is monitored in real time.，The construction data is clear at a glance。

 

For ten years，Xugong has achieved a leap from 11th to 3rd in the global construction machinery ranking.，It has ranked first in the domestic industry for 33 consecutive years.，Products are exported to more than 190 countries and regions.。

 

This decade，XCMG has manufactured products that enjoy a good reputation in the industry.“The world's first crane”、“The first dig in China”、“The world's first diamond”And so on more than 100 domestically produced first set of major equipment.，Solve the key projects in the global market、Difficulties in the construction of major projects。China's construction machinery represented by XCMG，It is continuously promoting the high-quality development of manufacturing industry.，Enabling China's economy。
