【In-depth Discussion on Modular Installation of HaiChuan】Steel Structure Modules for the 17 ZhongAn United Gasification Framework

Successful lifting of the first steel structure module for Zhong’an United gasification framework http://china.chemnet.com/ 2017-12-07 10:28:22 Sinopec News Network (Zhao Tianqi) On December 5, the first steel structure module for the gasification framework of Zhong’an United’s gasification unit was lifted successfully in just one attempt. The steel structure module to be lifted this time is a large-scale steel framework that has been assembled on the ground; it features three axes, two spans, and six columns. The total length of the module is 22 meters, with a width of 11 meters, and it consists of two floors. The total weight of the steel structure itself is 186.9 tons. When additional equipment such as steel grilles for the platforms, safety measures, anti-corrosion treatments, fire protection layers, and lighting fixtures are taken into account, the overall weight rises to over 200 tons. 　　To ensure that this massive structure weighing over 200 tons could be safely lifted and installed on a platform 66 meters high, the Project Management Department of Zhongan United, together with the project construction unit, carried out thorough planning prior to the construction work. In light of specific challenges such as the huge size of the structure to be lifted, the confined working environment, and numerous concurrent tasks, a on-site command team for modular lifting was established. A detailed lifting plan was developed and its feasibility was assessed, and guidance documents for the modular lifting of the gasification framework steel structure were prepared. During the lifting operations, strict on-site command and coordination were maintained, and the lifting procedures were followed carefully, which ensured the successful installation of the first steel structure module of the gasification framework for the gasification unit. The lifting of the remaining three steel structure modules for this framework will also be completed in the coming days. 　　Modular lifting can minimize work at heights, reduce safety risks, effectively ensure construction quality, and shorten the project timeline. The successful completion of the lifting of the first steel structure module for the gasification framework has provided valuable experience for the modular construction of large-scale structures in the Zhongan United Coal Chemical Project.

The assembly of the steel structure modular floor saves time on lifting operations at heights.
