Core 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].

Core Viewpoint - The recent Central Urban Work Conference emphasizes high-quality urban development, focusing on intrinsic development and urban renewal as key strategies for enhancing city aesthetics and characteristics [1] Group 1: Urban Renewal and Technology - The introduction of "pit air membranes" in urban renewal projects aims to reduce dust and noise, achieving a noise reduction of at least 20 decibels and dust isolation of 90% [3] - These membranes create a comfortable working environment for construction workers by continuously monitoring internal air pressure and temperature, ensuring fresh air circulation while filtering out dust [5] - The membranes also allow construction to proceed uninterrupted by adverse weather conditions, thus shortening project timelines [7] - This technology is being widely adopted in various cities for municipal engineering and urban renewal projects, providing a "silent mode" solution for urban construction [9] Group 2: Smart Urban Infrastructure - In Hefei, the implementation of a digital "ID" system for liquefied gas cylinders enhances safety through real-time monitoring and data integration into a smart regulatory platform [10][12] - The city has established a safety monitoring system for essential urban infrastructure, deploying 85,000 sensing devices across critical areas, which has led to over 1,100 early warnings for gas leaks and flooding [14] Group 3: Cultural Heritage in Urban Renewal - Urban renewal efforts include the protection and restoration of historical buildings and cultural sites, revitalizing old structures while integrating them into modern urban life [15][19] - In Harbin, the historical cultural district showcases century-old Russian architecture, blending tradition with contemporary aesthetics [17] - Kaifeng is focusing on the preservation of its ancient city wall, implementing micro-renovations to enhance cultural tourism while maintaining historical integrity [20][22] Group 4: Sports Facilities Integration - Shijiazhuang has integrated sports facility construction into urban renewal, creating nearly 1,000 sports venues, which has expanded recreational space for citizens and attracted various sports events [23][27] - The city has hosted over 1,000 sports events this year, enhancing community engagement and promoting a culture of fitness [29]

Group 1 - The central urban work conference emphasizes high-quality urban development, focusing on intrinsic development and urban renewal as key strategies [1] - Cities are integrating aesthetics and characteristics into urban renewal through careful planning and design [1] Group 2 - The introduction of "pit air membranes" in urban renewal projects, such as in Beijing, serves to reduce dust and noise, achieving a noise reduction of at least 20 decibels and a dust reduction rate of at least 90% [3] - The air membranes create a comfortable working environment for construction workers by continuously monitoring and regulating internal air quality [3] - The use of air membranes allows construction to proceed uninterrupted by adverse weather conditions, potentially saving up to two months in project timelines [4][6] Group 3 - The "silent mode" solution provided by air membranes is being widely adopted in various cities for municipal engineering and urban renewal projects [6]

Core Viewpoint - The implementation of a large-scale air membrane technology in the construction of the new sponge city project in Tongzhou, Beijing, aims to minimize dust and noise pollution, ensuring a better living environment for nearby residents [1][2]. Group 1: Project Overview - The air membrane is not an independent structure but a covering for the construction site of the new sponge city project, which is located in a residential area with over 18,000 residents [1]. - The project manager highlighted that traditional construction methods would significantly impact the daily lives of local residents due to dust and noise pollution [1]. Group 2: Air Membrane Technology - The air membrane technology is a new green construction method that combines dust prevention, noise reduction, energy efficiency, fire safety, and intelligence, supported by internal and external air pressure differences [2]. - The membrane material is made of high-density polyethylene, treated with three layers of special coatings, providing high strength and self-cleaning properties, capable of withstanding heavy rain and strong winds [2]. Group 3: Achievements and Benefits - The air membrane used in the project is the largest in Beijing, measuring 165 meters long, 80 meters wide, and 37 meters high, with a maximum height difference of 60 meters and a total area of 21,000 square meters [2]. - The project is the first in Beijing to use a diagonal net structure for securing the membrane and is the first nationwide to apply the air membrane throughout the entire construction cycle, achieving over 90% dust prevention and a noise reduction rate of over 71% [2]. - The air membrane also provides insulation benefits during winter, allowing construction to continue without delays due to cold weather, thus ensuring the health of workers and maintaining project timelines [3]. Group 4: Project Progress - The main structure of the "regulation pool + pump station" project within the sponge city initiative has been completed, and the project is moving into the electromechanical decoration and commissioning phase [3].
