Jinan，An ancient cultural city with a long history

With“Spring City”Be famous in the world

Subway，Push the city forward

It is a symbol of the development of the times.

Recently，Several XCMG Pump Trucks Gathered“Spring City”

Helping the Construction of Jinan Urban Rail Transit Line 6

Jinan Urban Rail Transit Line 640.1km，Construction has33 underground stations，It is the east-west backbone line running through the main urban area of Jinan.，It is also an important line in the second phase construction planning of Jinan Rail Transit.。The project construction is of great significance.，There are many difficulties in construction，It poses a severe challenge to the quality and performance of concrete machinery.。

● Jinan is rich in groundwater resources.，The geological environment is complex；

● The rail line runs through the main urban area，Limited construction area；

● AdoptCustomized high strength concretePouring，High strength、High viscosity，High requirements for pouring process；

Construction site，Configuration of XCMG concrete pump truckThe third generation of intelligent arm support technologyArt，Boom responds faster，Pumping is more stable；AdoptLarge displacement main pump、Large diameter climbing pipe，Higher pumping efficiency，Easy to deal with high intensity、Mass concrete construction。

Why is it cold and dry in winter?，The construction site of Jinan Rail Transit Line 6 can be constructed continuously in large quantities.？How to Solve the Problem of Concrete Construction and Curing in Winter？

It is well known，Temperatures below 0 degrees Celsius freeze the water in the concrete.，Destroy the concrete structure，Cause it to appear“It breaks at the touch.”The state of，Seriously affect the quality of the project。
