Beijing Tianma Intelligent (SH:688570) Bei Jing Ri Bao Ke Hu Duan·2025-12-03 11:23Core Insights - The Beijing Tianma Intelligent Control Industrial Base Phase II EPC project has reached a significant milestone with the successful application of the pit air membrane, marking the first instance of this technology in the Shunyi District, showcasing a breakthrough in innovative and green construction methods [1][3]. Group 1: Technology and Innovation - The air membrane covering system features both airtightness and intelligent control functions, effectively reducing dust, maintaining temperature, and lowering energy consumption during winter, thus creating a controllable "indoor environment" for subsequent pit operations [3]. - The air membrane technology is characterized by its large span, high efficiency, and intelligent features, providing a new solution for complex construction environments [3]. - The main structure of the air membrane is made from high-strength PVDF material, supported by a crisscross steel cable system, creating a highly stable load-bearing system capable of withstanding natural disasters, including typhoons up to level 12 and snow loads of 50 centimeters [3]. Group 2: Environmental Impact and Standards - The air membrane system acts as a fully enclosed, intelligent "protective cover" for the pit operation area, transforming traditional open pit work into a controllable "indoor factory" production, significantly improving the construction environment and reducing dust pollution [3]. - The successful application of the air membrane technology not only ensures the progress and quality of winter construction but also establishes a benchmark for the green and technological transformation of the local construction industry [3].
