Traditional excavation construction often faces environmental problems such as dust, noise, and rainfall erosion, etc. Especially against the backdrop of increasingly stringent environmental regulations, traditional protective measures are no longer sufficient to meet these demands. Excavation airsupported membrane technology utilizes a membrane structure supported by air pressure to create a fully enclosed construction space, thereby reducing disturbances to the surrounding environment at the source. It exhibits advantages such as environmental friendliness, energy efficiency, intelligent control, rapid deployment, and strong adaptability. Through its fully enclosed airsupported membrane structure, this technology effectively addresses the problems of dust, noise, and environmental pollution associated with traditional excavation construction, demonstrating particularly outstanding results in densely populated urban areas.
