At the construction site of Jianghan Shiqiao Project in Wuhan，Orderly construction by staff，Non-stop operation of construction machinery，Three XCMG rotary drilling rigs are carrying out pile foundation construction，From time to time, there was a sense of vibration under his feet.。

Jianghan Shiqiao is connected to Caidian.、Hanyang and Qiaokou are the main channels across the Hanjiang River.。The total length of the project is 4123 meters，The main bridge across the Hanjiang River is 855 meters long.，Two-way 6-lane design，The arch of the bridge is like a“Steel Rainbow”。

And support this.“Steel Rainbow”The pile diameter is 2 meters.，Pile depth 82-97m pile foundation，The geological strongly weathered conglomerate where the pile foundation is located、Moderately weathered conglomerate, etc，Rock hardness over 100MPa。

Introduced by XCMG for hard rock formationXR580HDLarge tonnage drilling rig，HavePowerful、High pore-forming quality and strong rock penetration ability，Hole forming time of single equipment 3-About 4 days，Overcome difficulties for major projects with absolute hard-core strength。

Xugong is still under construction.XR580HDRotary drilling rig not only has good construction performance，It is also full attendance and low failure.“Pacesetter”，The super stability of almost zero failure on site ensures the construction of the project.“Keep on gear”，The high working performance and piling efficiency are frequently praised by the project team.！

Takeoff rainbow、Cross the river，XCMG Rotary Drilling Rig Will Continue to Develop Bridge Foundation Construction，Tamping the foundation and erecting the steel and iron beam of a powerful transportation country。
