“Prepare to lift!”Accompanied by an order from the site hoisting commander in chief,October 18,The super-large outer dome module of Changjiang Nuclear Power Phase II Unit 3 with a total weight of about 600 tons,It landed safely and smoothly on the top of the nuclear island under the lifting of the 3200-ton Crawler Crane of Zoomlion.,It outlines the magnificent outline of the nuclear power unit.,It also marks that the construction of the main structure of the nuclear island has been basically completed.,It lays a solid foundation for the following installation, commissioning and grid-connected power generation.。
▲Zoomlion Crane Helps Lifting of Outer Dome of Unit 3 of Changjiang Nuclear Power Plant Phase II
In the construction of nuclear power projects,The hoisting of the outer dome module is a key milestone.。The module is located on the top of the nuclear island reactor building.,An irregular hemispherical head,The diameter of the base is about 52 meters.,The height is about 12 meters.,It is mainly used as the formwork for the concrete on the top of the nuclear island shell.,Provide support for subsequent pouring of nuclear island shell dome。The nuclear island shell mainly plays a protective role.,It is an important part of the nuclear island safety protection system.。
The total hoisting load of the outer dome module is about 600 tons.,The outer dome structure has a large size.、Characteristics of heavy weight and thin wall plate,It is very easy to produce deformation in the process of hoisting, which leads to difficulty in positioning.,Zoomlion 3200-ton Crawler Crane with millimeter-level lifting accuracy and smooth and efficient lifting action,The outer dome of Unit 3 of Changjiang Nuclear Power Phase II was precisely placed in the predetermined position.。
▲Hoisting site
Hainan Changjiang Nuclear Power Unit 3 is China's“Fourteen five”The first to start work“Hualong One”Unit。It is understood that,During the construction of Unit 3,Zoomlion Crane has always been fighting in the front line.,The hoisting of ring beam and ring rail was successfully completed.、Hoisting of ring crane main beam、Lifting of inner dome and other important lifting tasks,The smooth construction of the project provides a solid equipment guarantee.。
