基坑气膜为海绵城市建设树标杆

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].
