Abstract：
According to the external wall waterproof design requirements of this project, in order to avoid the large amount of bricks and the time-consuming problems of ordinary bricks and molds, lightweight prefabricated walls have been introduced to replace the traditional brick molds. In this paper, combined with the construction technology of waterproofing prefabricated wall in the project of the Changsha State Gold Center project, how to ensure the construction progress of the underground outdoor wall is discussed. The process, installation and effect of the prefabricated wall construction technology for the underground outdoor wall are introduced in detail.
