The core detection equipment of Jiangmen Zhongmei Experimental Detection Equipment Stainless Steel Structure smoothly completes the installation

The staff is installed in the main structure of stainless steel in the core detection equipment of the Jiangmen neutron experiment.

Jiangmen Daily News (Text/Picture Reporter/Zhang Haoyang Correspondent/Sun Zi French Liu Yuexiang) Reporter learned from the Institute of High Energy Physics of the Chinese Academy of Sciences (hereinafter referred to as the "High Energy Institute of the Chinese Academy of Sciences") on June 24. The core detection equipment of the sub -experiment -the last assembly unit of the main structure of the central detector stainless steel is lifted together, marking the successful completion of the central detector stainless steel main structure.

The detector of the Jiangmen Zhongmei Experiment Center is located in the center of a 44 -meter -deep pool in the underground experimental hall. Its main structure design of the stainless steel structure adopts a spherical mesh structure of a diameter of about 41 meters, also known as the stainless steel mesh. structure. It will carry 35.4 meters of organic glass balls, 20,000 tons of liquid flashing body, 20,000 20 -inch photoelectric pipes, 25,000 3 -inch photoelectric pipes, cables, anti -magnetic coils, and light panels.

The main structure of the stainless steel of the Jiangmen Zhongmei Experiment Center is composed of prefabricated welded H -shaped steel stitching through 120,000 sets of high -strength bolts. The structural manufacturing accuracy requirements are very high. It is currently China's largest single stainless steel main structure. Since the establishment of the item in 2013, the Chinese Academy of Sciences has collaborated with the design and production enterprises to overcome many process technical problems, solve the problem of welding deformation of large stainless steel complicated structures, and complete the high -precision pre -assembly of all components in the factory through special workflows and construction methods. At the same time, stainless steel surface coarse technology has been developed, and a high -strength stainless steel short -tailed groove rivet is developed aiming at the special needs of Jiangmen's neutron experimental projects.

He Wei, the head of the main structure of the stainless steel structure of the Jiangmen neutralized stainless steel, said that the main structural design and pre -research process of the main structure of stainless steel obtained a number of technical invention patents, which has also driven the innovation and development and comprehensive strength of related manufacturing companies. Among them, the stainless steel short -tailed groove rivet technology was identified by the China Machinery Performance Industry Association. It was first used in the field of stainless steel and steel. The relevant standards were released accordingly, filling the domestic gap.

The Chinese Academy of Sciences High Energy pointed out that the combination of the main structure of the stainless steel also means that the installation of organic glass balls on the spot is about to begin. The organic glass ball in Jiangmen Zhongmuzi Experiment Center detector structure is 35.4 meters, the wall thickness is 120 mm, and more than 600 tons. There is no precedent for production and construction in the world's largest organic glass structure in the world today. How to break through traditional craftsmanship and successfully complete this sphere construction in the short term is another huge challenge facing the project team.
