Recently，In Qingdao Electric Power Pipe Gallery Pipe Jacking Project

XugongXDN3000-RPipe jacking machine

Refreshed the pipe jacking machine of XCMG big bore.

Record of the highest hardness of rock crossing

It sets a new benchmark for the field of Trenchless engineering.

 

 

Qingdao{ Challenge the limits，One top to the bottom }

 

Qingdao Power Pipe Gallery Pipe Jacking Project

Total length of construction: 57m，The pipe diameter reachesDN3000

Facing the narrow construction site and complex geological conditions

XugongXDN3000-RPipe jacking machineWith an amazing performance.

The fastest single-day footage reached 10 meters.

Successful crossing hardness up to 160MpaRock strata

 

 

XugongXDN3000-RPipe jacking machine

The reason why we can be in such a harsh environment

Shine brilliantly

It is inseparable from its advanced technology configuration.

 

The machine is equipped with high-power cutterhead and high-torque reduction gearbox.

Excellent rock breaking ability

The main roof system has a fine adjustment mode.

Realize millimeter-level precision control

Ensure accurate and efficient construction

In addition，Its sludge feeding and discharging system is flexible and changeable.

Ffectively solve that problem of slag and stone deposition、Difficult problems such as large frictional resistance of pipelines

It provides a solid guarantee for the smooth construction.

 

 

In the course of construction

The XCMG service team showed

High sense of responsibility and professionalism

Facing the complex environment of the site and its surroundings

Xu workers are on standby 24 hours a day.

Provide technical support and solutions at any time

Ensure smooth construction

 

Donglin{ Act according to one's own circumstances，Make another success }

If the success of the Qingdao project is

A demonstration of XCMG's technical strength

So the Donglin substation supporting the power tunnel project

Smooth progress

It is a leap in XCMG's innovation.

 

 

XugongXDT31×Cantilever pipe jacking machine

In a weathered rock formation up to 102 meters long

Stiff“Chisel”Make a path.

It not only saves working hours and manpower,

It also creates a new type of cantilever pipe jacking machine.

The pioneer of underpass national highway operation

 

 

Facing the frozen soil、Weathered rock formations and

Multiple challenges such as soft soil soaked by water

The XCMG team did not flinch.

They draw lessons from the working principle of drilling shearer.

ForXDT31×The 30 pipe jacking machine is tailored

Super Long、Superhard bit

Successfully overcome the difficulties in the construction.

 

Final，In less than a month.

Safe crushing of 950 cubic meters of rock

It has won high recognition from customers.

 

 

Power Tunnel from Qingdao Power Pipe Gallery to Donglin Substation

XCMG pipe jacking machine is famous for its excellent performance and excellent service.

It has set new industry records again and again.

For urban construction and livelihood projects

Contribute one's own strength

 

Future

XCMG will continue to focus on market and customer needs

Continuous innovation of technology、Improve quality

For the smooth implementation of more major projects

Escort

Let's look forward to it together

More wonderful performances of XCMG pipe jacking machine
