The project must involve the road, the traffic does not delay! XCMG pipe jacking machine is really "jacking"

How to be safe without affecting traffic、Cross smoothlyGThe pipe jacking project of a mine in Shandong Province on the 18th Expressway has been accomplished.

And this project's“The main character”Namely——XugongXDN1800-RPipe jacking machine

The construction scope of the project isG18 Rongwu Expressway Building Control Area，Connect with the reserved pipeline of Weiyan Railway。AdoptPipe jacking technology construction，It can ensure the normal traffic of the expressway.，Save the cost of land acquisition and demolition，It has remarkable economic and social benefits.。

The crossing rock stratum of this pipe jacking is highly weathered gneiss.，And the most of the overlying sand layerThe small thickness is only 1m，There is a large risk of collapse during jacking.。In order to ensure the safety of pipe jacking，The customer purchased the domestic advanced Xugong by itself.XDN1800-R“Mud-water balance”Rock jacking equipment。

Due to the different shapes of flanges for railway reserved pipelines,，It has caused a lot of difficulties for the pipeline closure.。XCMG Technology、The service personnel and the construction party have made many on-site measurements.，Made3D model，Final adoptionCustomized processing and on-site adjustment of XCMGWay to complete the pipe connection.。

The construction process is carried out by two construction teams in shifts for 24 hours.，After nine days and nights，On average20 per daymThe pipe jacking operation was completed with high speed and efficiency.。

XugongXDN-RSeries pipe jacking machine is electric drive rock pipe jacking machine.，Primarily for gravel、Pebbles、A few boulders and rock strata。

The cutter head has high power，Strong rock breaking ability，Fine adjustment mode on the main roof，AchievableMillimeter-per-minute accuracy regulation，Meet the construction requirements of extremely hard rock stratum；The sludge feeding and discharging system can be realizedInside、External circulation、Bypass、External water supply、Straight rowFive mud circulation modes，Ffectively solve that problem of slag and stone deposition、Large frictional resistance of the pipeline and the like.；EquippedTelescopic anti-rotationDevice，Avoid the problem that the machine head is easy to rotate in the rock stratum construction process.。

This project is the first self-owned equipment of the project party.、Self-constructed pipe jacking project，“Efficient、Safe、Reliable、Easy to use”，This is the highest praise from the construction side for XCMG's pipe jacking machine.。At present，XCMG Pipe Jacking Machine in Egypt、Successfully applied in many key projects such as Brazil，Safety and reliability of equipment、Technical advancement and professionalism of service personnel、Dedication，It has won praise for Xugong brand.。
