Recently，XugongXDN1650-RPipe jacking machineEquipment Helps Construction of High-speed Railway Water Pipeline in Qingdao City, Shandong Province，From construction efficiency、The construction quality has handed over a satisfactory answer to the construction side.。

The crossing geology of the construction pipeline is sandstone、Strongly weathered mudstone、Slime, etc。Saturated uniaxial compressive strength of rock20-30MPa，Some of them are soft rock，VGrade surrounding rock，Rock uniaxial saturationThe compressive strength is 10-20MPa，It will soften into mud when it meets water.，It is easy to cause problems such as pasting the cutter head and high jacking pressure.，AndThe jacking pipe is cement pipe.，The difficulty of construction has also increased.。

XugongXDN1650-R Rock pipe jacking machine equipment withSecondary crushing function，Good performance and quality in sandstone formation，Cutter headSpeed is fast，The torque is large，The slag is melon-seed schistose rock，And that slag discharge speed is high.，High jacking efficiency。

 

XugongXDN1650-R Cutting outer diameter of rock jacking machine cutter headφ2080mm，Torque 294kN·m，Rotating speed4.8r/min，Weight of complete machine22.5t。Optimize the protection of the internal sensing part of the equipment，Equipped with composite rock cutter head，Multi-mode mud flushing system；Equipped with field handle function，Workers can operate the oil cylinder to extend and retract by themselves when lowering the pipes。

 

Inner diameter of jacking steel pipe for constructionDN1650mm，Length2m/Root，During site construction，Jacking speed up to1.2 meters/Hour，The equipment performs well and all functions meet the customer's construction requirements.。

At presentXCMG has a coverage of 300-4000mmPipe jacking machine with full range of pipe diameter，In Brazil、Tanzania、Indonesia、Successfully applied in many overseas key projects such as Malaysia。Rain and Sewage Diversion Project in Fengming Road, Xuzhou，The XCMG pipe jacking machine has successively passed through the full-section rocks.、Boulders、All clay formation，Rock hardness up to 120MPa，Fastest daily footage 4~6m，Breaking through the construction difficulties of extremely complex strata in the single jacking section of micro-pipe jacking in China。

With the gradual improvement of domestic basic engineering,，XCMG pipe jacking machine has good performance in terms of construction performance, equipment safety and stability.，XCMG Foundation will continue to focus on market and customer needs，Contribute to the Construction of People's Livelihood Projects。
