[0002] Environmental protection projects have adopted a variety of advanced technologies and equipment in noise prevention and control. Among them, foundation pit air membrane, as an innovative and efficient solution, has been widely used in construction sites in recent years. The foundation pit air membrane forms a closed or semi-closed building space through the internal and external pressure difference, effectively blocking the propagation path of construction noise, thereby achieving the purpose of noise reduction. This air membrane material is mostly made of new building materials such as PVDF, which is strong, durable, fire-resistant, and resistant to high temperature and ultraviolet rays. It has excellent sound insulation performance. The inner and outer membranes are designed to be a sandwich and hollow structure, which not only enhances the sound absorption and sound insulation effect, but also effectively blocks the dust generated during the construction process, further improving the construction environment foundation pit air membrane.

[0003] The existing foundation pit air film has obvious defects during long-term use. For example, a light-transmitting film is generally set on the top of the existing foundation pit air film to allow light to penetrate into the interior. However, due to the strong sunlight at noon or in the afternoon, the light may cause the temperature inside the foundation pit air film to be too high, causing discomfort to the construction workers and even affecting the health and work efficiency of the construction workers. Moreover, it is difficult for traditional foundation pit air films to grasp the status of the air film and its fixing ropes in real time. Once the tension is unbalanced, the air film structure may be damaged or even collapsed, posing a safety hazard. Utility Model Content
