月29日,高强C120混凝土从标有“1800米”字样的管道口汩汩涌出,输送进不停搅拌着的混凝土运输车中,这标志着徐工与双龙集团模拟620米超高层泵送试验圆满成功。 On October 29, the high-strength C120 concrete gushed out from the pipe port marked with "1800 meters" and was transported into the continuously stirred concrete transport vehicle, which marked the simulation of XCMG and Ssangyong Group's 620-meter high-rise pumping test A complete success. This is a leap forward in the technical field of the concrete industry in Jiangsu Province.

According to estimates, the successful pumping of C120 concrete through a horizontal coil of 1800 meters means that the vertical height of concrete pumping can reach 620 meters, which is equivalent to the height of 155 floors. Previously, the maximum pumping height during the construction of Zifeng Building, the tallest building in Nanjing, was only 381 meters, which also indicates that XCMG has taken another step in the field of high-strength concrete high-rise pumping.

The increase in concrete strength also poses challenges for pumping high-rise buildings. The strength level of the concrete pumped by this test was increased from C100 to C120. High-strength concrete has strong performance, but high viscosity and easy to block pipes, so this is a new challenge of extremely high difficulty.

The XCMG V7 series HBC10040V ultra-high-pressure vehicle pump used in this test is the product of the perfect integration of XCMG's experience and German technology through the complementary advantages of XCMG's acquisition of German Schweining Company in 2012. In order to meet the special requirements of this experiment, XCMG Shi Weiying also set up a guarantee team composed of pumping technical experts to provide professional technical support for the entire process of pumping construction by using an independently developed intelligent pumping data monitoring system.

XGMG Shi Weiying's general manager and party secretary Wang Gui said, "XCMG's strong strength and leading level in the field of ultra high-rise pumping provides a strong guarantee for the construction of this high-rise project. XCMG has always been committed to providing customers with high-quality concrete machinery sets Solutions. "

Since XCMG's ultra-high pressure vehicle pumps landed in the Nanjing market in 2017, it has assisted in the construction of ultra-high-rise projects such as Nanjing Global Trade Plaza (302 meters), German World Trade Center (321 meters), and Golden Eagle World (368 meters). Pumping construction experience.

Prior to this, XCMG Germany Schwein Company always maintained a global leading position in concrete ultra-high pressure pumping technology. Its equipment has participated in the construction of many supertall buildings around the world: Kuala Lumpur Twin Towers (452 meters), Taipei 101 Building (504 meters), New York Freedom Tower (540 meters), Saudi King Tower (1007 meters) and other major projects, setting a world record !! Continuously provide high-quality complete sets of concrete machinery solutions for global customers!
