Beijing Xinyuan Yijia Membrane Structure Technology Co., Ltd. has specialized in the field of membrane structures for many years, accumulating deep professional expertise. The movable track-based foundation pit air-rib system is a direct result of Xinyuan Air Dome's technological advancements. This innovative product integrates two core elements: air-ribs and a track system.
The air-rib component is crafted from specialized membrane material into curved tubular shapes. Once inflated, these tubes gain both rigidity and stability, forming a robust supporting structure. The track system provides mobility to the entire apparatus, allowing the air-ribs to move flexibly along the tracks.
In late 2024, the Long'ao Building Station project of Jinan Metro Line 7 became the first to utilize this technology. The station's location is particularly sensitive, being adjacent to the Jinan Municipal Government and situated alongside a main urban road. This meant that construction faced extremely stringent environmental protection requirements. The movable track-based foundation pit air-rib system proved highly effective here; it tightly enclosed the foundation pit, effectively preventing construction dust from escaping and minimizing interference with ambient air quality. Simultaneously, it reduced the outward transmission of construction noise, creating a relatively quieter environment for the surrounding area.
