Recently，6 developed by China Railway Construction Heavy Industry.6m Slurry Balance Shield Machine in Bangalore Metro Phase II, IndiaVellaraThe station came out of the hole smoothly.，It has become the first equipment for the whole line of the project to run through the tunnel.。

“Mother Earth”Slurry Balance Shield Machine Helps India's Bangalore Metro Project Complete

The equipment is one of the four slurry balance shield machines used by China Railway Construction Heavy Industries in Bangalore Metro, India.，The customer names it.“Avni”，It means“Mother Earth”。The total length of the first tunneling section of the equipment is 1085 meters.，It was successfully completed on January 6 this year.。The second section of this excavation is 1131 meters long.，The geological conditions are complex，It has to pass through many residential areas and several centuries-old temples.，Extremely high requirements for land subsidence control。

  

Localized service team escorts shield machine

 For the above construction difficulties，Railway Construction Heavy Industry R & D and Design Team Tailored for Equipment“China Programme”。Aiming at high strength of rock stratum、There are a large number of boulders and uneven hardness of the formation.，The shield machine is equipped with high-strength composite cutter head and large-size hob.，Optimized hob trajectory、And that structure of the cutterhead panel is reinforce.，Anti-loosening measures for hob are added，Achieve efficient rock breaking。At the same time, it is equipped with gas-liquid independent balance control.、Fficient slurry circulation system、Advanced technologies such as synchronous double-liquid grouting system，It has effectively solved the construction problems in the construction of Bangalore Metro Tunnel.，Make it easy for equipment to cope with complex geological environment。

  

Equipment acceptance is offline

Since its launch in early 2020，The excellent performance and performance of the equipment have been fully proved by practice.，Highly praised by customers and owners，It highlights the advantages and strength of Railway Construction Heavy Industries in the South Asian Metro market.。
