WithXugongXTR4/260 cantilever tunnel boring machineYes

Out of the hole

Total length 715mThe Miaozi Tunnel was successfully completed.

It has opened up a key link for the whole project construction.

XugongXTR4/260 entered the hole in late March     Daily footage of tunneling construction 8-15mMonthly footage not less than 200mThe construction progress is one and a half months ahead of schedule.The construction progress of the project is greatly advanced.

 

The tunnel as a wholeIV、VClass I surrounding rock is the main type，3 widem，High 2.8mSmall-section water conservancy tunnel，The construction efficiency of traditional drilling and blasting method is low.，High cost。It is finally adopted after the research of the project department.The fuselage is only 2..1mWide XCMG latest modelXTR4/260 cantilever tunnel boring machineCarry out construction。

 

 

XugongXTR4/260 Tunnel Boring MachineMachineThe narrowest body in the country，Equipped with large taper cutting head，The cutting force is large、Strong rock breaking ability、The cutting vibration is small，EspeciallyAtOver-owingIn terms of diggingGood control，A large amount of spray concrete can be saved。The packing base is adoptedSpiral seal structure，Ffectively prevent dust from entering，Improve product reliability。AdoptExcavation by mechanical method，It effectively reduces the labor intensity for the front-line workers.。

 

 

It is reported that，The project is determined by the State Council."172"Major water conservancy projects，It is also Sichuan Province"Five horizontal and six vertical"An important part of the ecological water network for water diversion and replenishment。Efficient construction of XCMG roadheader，Received unanimous praise from customers.，It has won praise for Xugong brand.。
