Ten Years of the New Era

XCMG Foundation has been successfully developed.

45 models 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.

Help China's Traffic Open the Way in Every Mountain，Bridge in water

In the process of super bridge and tunnel construction, XCMG rotary drilling rig“Super large、Super deep、Superhard formation“Construction performance
It's also escalating.、Refresh

Super deep hole：143m

Jiaojiang Bridge on Hangzhou-Shaoxing-Taiwan Railway

Four large-tonnage rotary drilling rigs of XCMG appeared on the same stage in the construction project of Jiaojiang Bridge on Hangzhou-Shaoxing-Taiwan Railway，AmongXR550DConstruction depth of rotary drilling rigUp to 143m！

 

XugongXR550DRotary drilling rigSatisfiableMaximum drilling diameter3.5m、Maximum drilling depth 146mThe construction of。Use XCMG first during constructionXR400D、XRS1050 Drilling 100mDepth，And then useXR550DCarry out relay construction。High construction quality of the project，Verticality is less than 0.3%，Its high-quality piling effect has been highly recognized by the project department and users.。

Superspeed：145 days

Huangmaohai Bridge

Huangmaohai Bridge, one of the control projects of Huangmaohai Cross-sea Passage，Pile group foundation is adopted for the main pier，3 meters in diameter，Pile length 110m XCMGXR550DAndXR580HDRotary drilling rig faces tens of meters of granite.，By virtue ofEfficientConvenient、Super deep pile、Super largeHoles and other technical advantages and product performance，102 pile foundations of main tower，XCMG rotary drilling rig completed the pile foundation construction of this super project in only 145 days.，IThe proportion of similar piles has reached 100%，The quality of the project is excellent。

 

Superhard rock：2m high core

Linhuaiguan Bridge across Huaihe River

Linhuaiguan Bridge across Huaihe River，Facing the main pier36 piles，Maximum drillingDiameter 2.8m，MaxDrilling depth 94mLeft and right，The construction conditions of the rock layer into the rock are the weathered gneiss.。

 

6 sets of XCMGXR580HDRotary drilling rig relies on the excellent performance of equipment and professional customized construction technology.，Take out at one timeDiameter 1.5m，High 2.0mLeft and right intact cores，Defend the field with hard-core strength“Overlord”Status。 

Extra large diameter：4m

Maanshan Yangtze River Rail-cum-Road Bridge

Total Height of Main Pier of Maanshan Changjiang Rail-cum-Road Bridge 345m，The tallest bridge tower in the world。60 piles with diameter of 4 are adopted for the foundation of main piermBored pile，It is the largest and largest diameter bored pile in the world.。Xugong55 tons per meterAlmost all of the above types of rotary drilling rigs are assembled here.，The average monthly working hours of each vehicle areMore than 500 hours，Full load continuous operation。

  

The No.3 pier of the bridge consists of 68 cast-in-place piles.，Diameter 3m，Borehole length 95m，Pore-forming depth up to 122.5m，Rock penetration depth 71.4m，The pile bottom shall enter the medium cemented argillaceous sandstone layer.。XCMG rotary drilling rig groupRealize 1 pile per day，Effectively guarantee the project duration node。

Super large tonnage：XR1600E

“The world's first diamond”Borehole diameter 7.5m，Depth 190m

This July，“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.。

  

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.，Modular design makes this“Behemoth”It can also adapt to the bridge on the sea.、Offshore wind power、Superhard formation、High altitude and other extreme working conditions。
