In the secret recesses of a bustling city
The tunnel project connects every corner of the city.
Tunnel construction, however, needs to overcome not only
The geological conditions are complex、Poor construction environment and other problems
Select stable equipment to ensure construction safety
It is also the most important thing
It is more than 40 meters underground from the surface of the Yangtze River.
Xiao Ke received such a difficult task.

Wuhu Chengnan River-crossing Tunnel
Wuhu Chengnan River-crossing Tunnel
There are service items this time.“The first tunnel along the Wanjiang River”Wuhu Chengnan River-Crossing Tunnel，The tunnel connects Weiyi Road, Erba Town, Jiujiang District, Wuhu City in the north.，Under the Yangtze River，South to Dagongshan Road, Yijiang District, Wuhu City。Total length of tunnel section 4.94km，Wherein the length of the shield tunnel section is 3.95km。
At high pressure、The space is narrow、Under the muddy surface of the Yangtze River，Shield propulsion needs to crack the sand、Stone、Earth，Uneven hardness、Super sticky、Super hard、Crossing of more than ten kinds of complex strata such as fracture zone，A little carelessness may cause slurry at the bottom of the river.、Water and sand gushing in tunnel，In this case, the requirements for various parameter control and tools are very strict.。
Tunnel construction shield driving
Shield Machine is the key equipment in tunnel construction.，In order to ensure that its operation is always in a healthy state,，According to the change of the cutter monitoring system and the tunneling parameters of the Shield Machine,，Formulate the tool change plan。When replacing the cutter head for the Shield Machine，The cutter head of the shield machine shall be locked by compressed air.，Ensure that the shield machine remains stationary during the cutter head replacement，So as to ensure the safety of construction personnel.。So in this project,，The selection of air Compressor equipment is very important.。
Key points for selection of air Compressor equipment
Sufficient gas
Air Compressor needs to be placed on the ground，Laying pipes to enter the tunnel，Connect the air intake point of the shield machine to provide support，The air compressor is required to have strong power output.。
And that performance is stable
When replacing the cutter head，The cutter head of the shield machine shall not swing at all.，Therefore, the air compressor gas supply to ensure absolute stability.。
XAHS710E
Look for pressure and plenty of gas.
Air compressor equipment with stable performance
The client chose Ke's.

See how this energy-efficient partner successfully solved the problem？
StableGas Volume，Escort
XAHS710EElectrically driven mobile air compressor
Two Atlases were selected for the project.·Copco
XAHS710EElectrically driven mobile air compressor
For gas supply，In the course of use，
XAHS710EThe air compressor shows excellent performance.，
It can continuously provide the gas volume needed by customers.，
To ensure the smooth replacement of the cutter head of the shield machine，
Win customer recognition with various advantages。
Advantage one：Motor protection class isIP55
The displacement reaches 21.5 m³/min，Pressure up to 12 bar，Insufficient pressure or flow problems are swept away。
ByIP55 degree of protection、FPowered by high performance motors with insulation grades，The use is more reassuring。
Advantage two：The performance is not stable“Drop the chain”
AdoptIP65 electric control cabinet with high protection performance，Provide a short circuit、Overload dual protection。
With Atlas·Kopko screw rotor，And that reliability is high，And that service life is long，And provide reliable guarantee for that replacement of the cutter head of the shield machine.。
Advantage three：Free movement and more efficient construction
The whole machine is compact in structure，Flexible and light，Strong mobility on site。
Integrated controller provides various display and alarm functions，And that construction efficiency is greatly improve.。
Advantage four：Energy saving and emission reduction“The Green Guard”
Its electric drive design makes the air compressor more energy-saving and environmentally friendly in the operation process.，In line with the concept of green development。
Ability to significantly reduce operating costs，Bring high economic benefits to customers。
Have such a long service life、Low breakdown and maintenance costs、The operation cost is low、But also free from dependence on fossil fuels.，Greatly reduce energy costsXAHS710EElectrically driven mobile air compressor，It can not only meet the needs of the project，There is another obvious advantage.——Total cost of ownership of equipment(TCO）Lower，Help you complete projects more confidently and economically！
