Successful application of XCM80 double-wheel mixer in super-deep mixing wall of Pudong Airport!
September 21, 2022
Recently，XCMG double wheel agitatorXCM80 arrived in Shanghai and participated in Shanghai Pudong AirportT3 Terminal construction。Pudong International Airport is 4FClass a civil airport，It is one of the three major gateway hubs in China.，Member of Yangtze River Delta International Air Cargo Hub Group，Member of East China Airport Group，The largest hub airport in East China、Gateway Airport。

XugongXCM80 double-wheel mixing still belongs to the piling industry.“Rookie”，When the construction party is evaluating whether the Pudong Airport can use the double-wheel agitator.，It is also the deduction of several schemes.，Many discussions from the construction scheme to the process and method，XugongXCMIn the early stage of 80 double-wheel stirring, 20 pairs were carried out with a depth of 80.--Construction of 85m mixing wall，It is necessary to extract cores after the wall is formed to determine whether the equipment has the construction capacity of the project.。
If it works，The design Institute will be based on XugongXCM80 Double wheel agitator has developed a new process method and industry standards and popularized them throughout the country.。
Can XCMG's double-wheel stirring be a hit?？
XugongXCM80 isStructure of the First Domestic Suspension Milling Device for Wire Rope，Special main engine and wide-spread crawler chassis，Compare with pile-frame type double-wheel stirring，Balance stability and mobility，Security has been greatly improved。The construction depth is 85 meters.，It is the depth of double-wheel mixing construction in China.“The ceiling”，Combined with XCMG Double Wheel Milling technology，Meet the construction requirements of ultra-deep and ultra-hard diaphragm wall mixing wall。Real-time Milling State Detection of Milling Head，And correct that deviation in real time according to the attitude.。
XugongXCMThe main engine height of 80 is no longer limited by the construction depth.，The height of the whole machine is controlled atBelow 18 meters，The powerful Cummins engine continuously outputs surging power for the whole machine.，Rexroth Hydraulic System and Engine Power Optimization Match，Higher engine utilization。
The geology of Shanghai is mostly soil layer，Optimized Structure of XCMG Double Wheel Mixer Full Section Non-blind Area Swing Milling Mixing Wheel，On the premise of fully ensuring the mixing capacity, the rock entering capacity is further improved.，Formation adaptability is more prominent，Easy to win the first opening，Washover the middle width is no problem.，Comprehensive construction efficiency increased year on year30%Above。
At Shanghai Pudong AirportTDuring the construction of Terminal 3，XugongXCM80 Double Wheel Zero Stirring Fault、And that construction is efficient。Under the condition that the construction depth of the test tank is 85m，The completion time of each slot is about 8 hours.，The downcut process is at 4.-About 5 hours，Lifted into a wall at 2-3 hours，Average milling mixing speed over 20 meters per hour。
After the wall is formedNo broken core during coring，The hardness is much higher than the design requirement of 0.8MPa.It has been praised by customers, general conTractors and owners.。
XugongXCM80 double-wheel mixer is an innovation and breakthrough based on the development of double-wheel Milling Machine by XCMG for many years.，Use deep technical accumulation，Blend new construction technology and method，Weed out the old and bring forth the new，It has aroused widespread concern and strong crowd in the industry.。XCMG Foundation will live up to expectations，Work for a long time、Steady and far-reaching，Develop more new products，Helping Global Infrastructure Construction。
