In the hearts of customers, XCMG Shuanglun stirred Qingdao Metro to build a water-stop curtain!

Recently，XugongXCM25、XCM40Double Wheel Milling MixerConstruction of the second phase of Qingdao Metro Line 7。Following last NovemberXCM25 First entry of XCMG double-wheel agitator，The excellent construction performance has led to the re-introduction of Qingdao Metro Waterstop Curtain Project.XCM40，XCMG team grows again。

The total length of the project line is about 16.877km，Strata in the construction area“Soft at the top and hard at the bottom”，The stratum often causes the problem of water leakage during the excavation of foundation pit due to insufficient depth into the rock.。

Compared with other waterproof curtain construction method，Double wheel stirringStir deeplyConstruction methodAnd that cost is low、And that work efficiency is high、Adapting to the site and becoming the preferred construction method of waterproof curtain。The deep mixing technology of double-wheel mixing method uses two groups of milling wheels to rotate around the horizontal axis.，Forming rectangular reinforced water stop wall，The rigidity of the wall is high、Low noise，It has good impermeability，PerfectAnd that problem of wat leakage is solved.。

Face hardness up to10-20MpaThe rock formation，XCMG double-wheel deep mixing into rock stratum，Strong cutting，Crush the rock formation，Use local materials，Delivery high pressure water pump，Stir well。At present, construction has been completedDepth 4.5m-25mNot equal、Thickness 0.8mThe cutoff wall，Construction efficiency 6 slots per day，Fully meet the construction requirements。

The efficient completion of the project is inseparable from the super performance of the equipment.

The efficient completion of the project is inseparable from the super performance of the equipment.。XugongXCM25、XCM40 double-wheel mixer adopts mature main machine of Rotary Drilling Rig.，Can be realized quickly“One machine for two purposes”；Quare guide rod type milling device structures，Ensure the construction accuracy；Milling head can realize cylinder pressurization，Double-oil cylinder drill rod clam structure and guide structures，Improve the rock mixing capacity；Real-time monitoring and control of cement slurry injected during construction，High pressure air flow and velocity，Meet the visualization requirements。

After the customer uses the XCMG double-wheel mixing product，A sincere boast：The overall performance of XCMG equipment is stable，Durable and easy to use milling wheel，The maintenance cost is low，It is our best choice for construction.。

Under the dual guidance of technological innovation and customer demand，XCMG Foundation will surely live up to its mission，With“Leading technology、Use without destruction”Build the most important tool of the country，Be a pioneer in technological innovation，Continuously improve the intelligence of products、Level of digitization，Help urban infrastructure。
