The "concrete" heart makes great achievements again! Zoomlion Spreader Helps Cap the Outer Dome of Sanao Nuclear Power Unit 1

November eleventh，The outer dome structure of Unit 1 of CGN Zhejiang Sanao Nuclear Power Project was successfully capped.，It marks the completion of the main structure of Unit 1.，It has laid a solid foundation for the follow-up test.。At the scene，Zoomlion's spreader and other equipment efficiently and reliably complete the construction task，Assist“Hualong One”Mass construction has taken another solid step.。

As the first in the Yangtze River Delta region,“Hualong One”Nuclear Power Project，Six sets of Sanao nuclear power plants are planned to be built“Hualong One”Unit，Unit 1 adopts an advanced double-layer containment design.，The outer containment consists of a cylindrical structure,、A hemispherical dome structure and an externally hung wat tank.。Concrete pouring technology is used in the capping work of the hemispherical dome structure.，After completion, the safety and tightness of the unit will be greatly improved.。

During casting in place，Zoomlion's multiple Spreaders with superior performance and efficiency，It provides strong support for the smooth progress of the project.。The overall height of the outer dome structure reaches 63.4 meters，At this height，The placing machine of Zoomlion can still carry out the pouring task stably.，Provide complete solutions for customers，Finally, high quality is ensured at the same time of rapid concrete forming.，It is appreciated by the project party and the construction party.。

“Our spreader products are installed in a variety of ways.，Be able to adapt to various complex construction environment，It uses a reinforced pipe tower structure.，So that that deformation of the top of the tow body is reduced by 20 percent%-25%，Thereby improving the precision of concrete pouring.，Reduced hose wiggle，And ensure that pouring quality.。The main structure of the boom and underframe of the spreader has passed the fatigue test of 450,000 m3 bench.，And that fatigue life is long，By using special materials and process design，The service life of pipe fittings has also been significantly improved.，Ensures the stability and durability of the equipment。”The person in charge of Zoomlion Concrete Machinery introduced.。

Since this year，Zoomlion's various equipment continues to be active in the front line of nuclear power construction，Participated in the completion of Zhangzhou Nuclear Power Unit 3、Changjiang Nuclear Power Unit 3、Important nodes of major projects such as Unit 1 of Huaneng Shidaowan Nuclear Power Base Expansion Phase I Project，Helping China's independent third-generation nuclear power“Hualong One”New breakthroughs have been made in unit construction.。
