Model project! XCMG Pipe-Jacking Machine is a long-distance pipeline network for nuclear heating.

Break through 140 MPa hard rock

XCMG Rock Pipe Jacking Machine Successfully Passes Through Hard Rock

Refreshing XCMG big bore Pipe Jacking Machine Crossing Rock

Highest hardness record

Nuclear heating long-distance pipeline network project from Haiyang, Yantai to Rushan, Weihai，It is the first long-distance nuclear heating pipeline network project across prefecture-level cities in China.，Cross-regional interoperability and sharing of zero-carbon heat sources will be realized.，To promote the coordinated development of double carbon economy in Yanwei region、The integrated development of Jiaodong economic circle is of great significance.。

This section of pipe jacking project is quite representative.，Yes“Long distance、Cross-regional”Nuclear Heating Model Project，Not only the rock hardness is high,，And that single-section high-hardness Jack distance is long.，The difficulty of construction has also increased.。

XugongXDN1800-R Rock jacking machineCross Provincial Highway 202、Into the mountain，The whole section of jacking formation is hard rock.（Granite）And a few weakly weathered rock strata.，Rock hardness is 120~140MPa Left and right，Single-stage jacking 210m，Jacking diameter 1.8 meters、2m long cement pipe，The final time is 58 days，Get out of the hole smoothly。

It was Xugong who conquered the hard rock of the mountain.XDN1800-R Rock jacking machine，Adopt composite rock cutter head，The equipment has the function of secondary crushing，Facing the weathered rock、Hard rock and other geology，Daily footage of up to 6 meters，Up to 8 meters。

In the process, XCMG technicians gave construction suggestions in time.，Finally, XCMG pipe jacking machineFrom construction efficiency、Construction qualityHanded in a satisfactory answer to the construction side.，Nuclear heating for Yantai Rushan in Haiyang City, Yantai City, Shandong Province（Haiyang）The pipe jacking construction of the project contributed to the strength of XCMG.。
