Core Viewpoint - A giant white dome in Jinan, Shandong, known as a "giant pillow," is being used as a protective measure during the construction of a large commercial complex to minimize dust and noise pollution in the surrounding area [1][5]. Group 1: Environmental Impact - The dome, officially called a "gas-supported foundation membrane," can block 90% of dust and reduce construction noise by 80% [5]. - It serves as a "green protective cover" that can withstand wind, rain, and snow, allowing construction to continue even during adverse weather conditions [5]. Group 2: Safety and Technology - The internal control system of the dome continuously monitors air pressure and temperature, ensuring a safe working environment [7]. - Four large air volume fans provide fresh air circulation, and plans include installing spraying facilities to control dust within the dome [9]. - The membrane material, made of PVDF, blocks 90% of UV rays and has a high thermal reflectivity and dissipation rate, with a B1 fire rating for enhanced safety [9]. Group 3: Future Applications - After the project is completed, the dome will be dismantled, but this eco-friendly construction model is expected to be promoted in municipal engineering and historical district renovations in Jinan [11].

Group 1 - The giant white dome in Jinan, Shandong, is a "gas-supported foundation membrane" designed to minimize dust and noise during the construction of a large commercial complex [4][2] - The dome, approximately 50 meters high and covering an area equivalent to 2.5 football fields, can block 90% of dust and reduce construction noise by 80% [4] - The dome's structure allows for a spacious interior without the need for load-bearing beams or columns, facilitating the entry of large construction machinery [6] Group 2 - The internal control system of the dome continuously monitors air pressure and temperature, ensuring a safe working environment [9] - The membrane material used is PVDF (polyvinylidene fluoride), which blocks 90% of UV rays and has a high thermal reflectivity and dissipation rate, along with a B1 fire rating [9] - After the project completion, the dome will be dismantled, but this eco-friendly construction model is expected to be promoted in municipal engineering and historical district renovations in Jinan [11]
