Through the power tunnel, the XCMG pipe jacking machine jacked 30 meters in a single day

Recently，XugongXDN3000-SPipe jacking machine“Steel pangolin”Break through the ground，Wuhan Nanniwan Avenue Power Tunnel Project Successfully Completed。

Nanniwan Power Tunnel Project is the first batch of pilot projects for Wuhan to build a world-class urban power grid.，Total length of tunnel section 6.299Km，Covering depth of pipe jacking 5~15m，There are 22 working wells in total.，The inner diameter of the tunnel is 3.mAnd 2.7m，Construction through complex strata，Pipe jacking construction is extremely difficult.。

Precast circular reinforced concrete pipe shall be used for pipe-jacking tunnel.，The interface adopts"FType"Steel socket，Built-in wedge-shaped rubber water stop ring。

XugongXDN3000–SStrive to be a pioneer in this project，The jacking distance of this section is up to 618m，Jacking up to 30 in a single daym，Efficient and precise jacking is quite recognized by the construction side.。

XugongXDN3000-SThe pipe jacking machine is aHigh performance electric drive pipe jacking machine，The deviceComprehensively improves the cutting coverage rate and the stirring rate, and can be applied to various complex stratums.；Equipped with high-performance power drive device，Sufficient power，And that speed regulation range is wide。

Use of key device power spindle with grease pump，HaveWear resistant、Resistant to corrosion、Reliable operation and the like.，Good sealing performance can be ensured even under poor lubrication conditions.，And that seal reliability and the service life of the deceleration part are greatly improved.。
