Core Viewpoint - The article highlights the innovative use of a "balloon" structure, known as a pit gas membrane, at the Honglou 1905 construction site in Jinan to mitigate dust and noise pollution during construction activities [2][3]. Group 1: Project Overview - The Honglou 1905 project is located in a sensitive area near Shandong University and other institutions, necessitating measures to minimize environmental impact [3]. - The gas membrane covers an area of approximately 20,000 square meters, with dimensions of over 150 meters in length, over 100 meters in width, and about 50 meters in height, totaling a surface area of around 30,000 square meters [3]. Group 2: Environmental Impact Mitigation - The gas membrane structure is designed to achieve "three protections": it can reduce dust by approximately 90%, lower construction noise by over 80%, and prevent rainwater infiltration, thus ensuring environmental protection, noise reduction, and operational capability during rainy seasons [3][4]. - The membrane is made of PVDF material, which is only 1 millimeter thick but blocks over 90% of ultraviolet rays, and features ventilation systems to maintain a comfortable internal environment [5]. Group 3: Construction Timeline and Technology - The project is expected to begin earthworks by the end of June, primarily involving mechanical operations until the end of September, with underground foundation work starting in October [4]. - The gas membrane incorporates advanced technology, including a PLC intelligent control system that allows for real-time adjustments of internal conditions, ensuring safety and efficiency during construction [5].
