Helping the Construction of Sichuan-Tibet Railway

The Sichuan-Tibet Railway is hailed as a miracle of human engineering.，It is the second railway to Tibet in China.，It is also a key national planning project.，Far more difficult to build than the Qinghai-Tibet line。

Where is the country in need?，Where does the figure of XCMG equipment appear?。Since the construction of the Sichuan-Tibet Railway started,，XCMG is deeply involved in many kinds of equipment，Quality and service has been well received.，Among them, the occupancy rate of new XCMG Rotary Drilling Rigs from Litang to Nyingchi is as high as 90 percent%Above，It covers a variety of models ranging from 24 tons to 70 tons.，It can be said to be an all-star family attack.。

Recently，The bridge piles on the west bank of the Boduizangbu Bridge on the Sichuan-Tibet Railway have been basically completed.，More than 70,000 meters in total。This is after the successful pile test of XCMG Rotary Drilling Rig in 2022.，XCMG Rotary Drilling Rig Group Overcomes Cold、High altitude，Give full play to cold resistance、Technical advantages of hard rock breaking，The fruitful results of a year's struggle。

It is understood that，Bodui Zangbute Bridge is located in Bomi County, which is known as the National Geopark.，Altitude 3000mLeft and right，Total length 13.9 kilometers，It is the longest bridge between Changdu and Linzhi on the Sichuan-Tibet Railway.。

The east bank of the river is close to the mountain.，The formation is more complex，Covered with cobblestones and accompanied by large floating stones，Pile diameter 1.25 meters，Pile depth 30-50 meters，The floating stone is composed of granite.，The hardness is 120MpaLeft and right，The hardest one can reach 150.Mpa，So that that drill of the traditional Pile Driver is extremely difficult，Low rock breaking efficiency，Construction progress is affected。

Face this“Tough bones”，The project team unanimously decided，Let Xugong take the lead。So XugongXR280EStrong approach of rotary drilling rig，Its power head has standard mode and rock entry mode.，Respectively for soil and rock operations，Equipped with automatic rotation function，Rotating speed can be adjusted continuously in standard mode and rock-entering mode.，Ensure efficient drilling，The actual application effect in the construction site of Sichuan-Tibet Railway is1-Hole-forming in 2 days，Be excellent at one time，It has won the unanimous praise of customers and project departments.。

“XCMG rotary drilling rig is very convenient for daily maintenance，BasicFull attendance，It has always maintained efficient operation.。”The project manager praised it.，“XCMG also providedStationed services，Escort the normal progress of equipment and projects，We are very satisfied。”

As an important part of China's medium and long-term railway network planning.

Sichuan-Tibet Railway and the Economic and Social Development of the Western Region

Play a vital role.

XCMG will spare no effort

For the smooth progress of major national projects such as the Sichuan-Tibet Railway

Keep delivering more“Efficient、Safe、Reliable”Construction machinery
