    Innovative Air Supported Solutions for Foundation Pit Engineering

    2025-11-13

    Air-supported structures are not only used in large venues like warehouses and sports stadiums, but also demonstrate unique advantages in underground parking garages, building foundations, and underground archaeology. Traditional foundation pit construction is often limited by weather changes, dust pollution, and noise disturbances. The emergence of Liri Air-Supported Structures offers a new fully enclosed construction solution for underground engineering that is efficient, safe, and environmentally friendly. Excellent Environmental Performance, Creating a Clean Construction Environment. By forming a fully enclosed construction space, air-supported structures effectively contain construction dust and prevent impact on surrounding air quality. Meanwhile, their excellent sound insulation significantly reduces construction noise and minimizes disturbance to nearby residents, truly achieving a combination of green construction and environmental protection. Upgraded Safety Protection, Coping with Complex Construction Environments Foundation pit engineering has extremely high safety requirements, and air-supported structures, with their excellent structural stability and protective performance, provide a solid guarantee for construction. Their excellent rain and snow protection performance ensures structural stability even in severe weather, preventing rainwater and snow accumulation from affecting the foundation pit. Furthermore, air-supported structures possess excellent wind and fire resistance, effectively mitigating natural disasters and unforeseen risks, minimizing construction delays and economic losses. Intelligent System Control Ensures Stable and Efficient Operation Modern air-supported structures are equipped with intelligent control systems that monitor key data such as internal air pressure, temperature, and wind speed in real time. The system automatically adjusts air pressure and fresh air volume based on monitoring results, ensuring the structure remains in a safe and balanced state. This intelligent control not only improves structural stability but also provides continuous and safe operational support for complex foundation pit construction. Efficient Space Utilization Meets Diverse Construction Needs Air-supported structures adopt large-span designs without any internal column supports, providing great convenience for the movement of…

    Foundation pit air dome covering construction site for dust and noise reduction

    Can a air dome reduce pollution at construction sites?

    2025-08-27

    Foundation pit construction has traditionally been an open-air operation, where wind, rain, dust, and noise often affect both progress and the surrounding environment. With the development of the foundation pit air dome, this conventional method has gradually shifted toward a new stage of indoor construction. 1. Weather Resistance: Enabling All-Weather Construction In the past, foundation pit construction was significantly constrained by weather. Rainy and snowy days turned construction sites muddy, making it difficult for machinery to operate, increasing worker safety risks, and frequently delaying progress. The air dome fully covers the construction site, protecting the internal environment from wind, rain, and snow. Even under adverse conditions, the construction process can continue smoothly, significantly improving schedule stability. 2. Reducing Pollution: Less Noise and Dust Dust and noise are two major problems in urban construction management. The enclosed structure of the foundation pit air dome can block approximately 90% of dust, significantly improving surrounding air quality. It can also reduce noise by about 80%, minimizing the impact on nearby residents and creating a more harmonious relationship between construction sites and communities. 3. Structural Advantages: Creating a Spacious Open Space The foundation pit air dome is an air-supported structure without beams or columns. It relies on the pressure difference between the inside and outside of the membrane to maintain stability. This not only simplifies the construction process but also provides a large open space—over 50 meters in height—allowing large machinery and equipment to enter and operate more easily, thereby improving construction efficiency. 4. Material Performance: Multiple Protections of PVDF Membrane The PVDF membrane, the core material of the air dome, offers outstanding performance. It blocks about 90% of UV rays, protecting staff and equipment. It also provides excellent thermal insulation and heat dissipation, reducing heat in summer and retaining warmth in winter, thus…

    What problems can a foundation pit air dome solve on construction sites (4)

    What problems can a foundation pit air dome solve on construction sites?

    2025-08-05

    In today’s rapidly advancing urbanization, dust and noise issues at construction sites not only affect the quality of life of surrounding residents but also become a focus of social attention. The shortcomings of traditional foundation pit construction methods in terms of environmental protection and efficiency have put greater pressure on construction companies in terms of environmental protection and project schedule. In response to this pain point, Liri Dome has innovatively launched the foundation pit air dome technology with rich experience in environmental space solutions, providing a new mode of environmental protection, efficiency, and safety for construction sites. Control dust and noise Traditional foundation pit construction often leads to complaints from surrounding residents due to dust and noise issues, especially in urban core areas where environmental management is more difficult. The foundation pit air dome adopts a fully enclosed design to control dust and noise from the source. In the construction area covered by air dome, the amount of dust overflow can be reduced by 90%, and the construction noise can also be reduced to below 50 decibels, which is equivalent to the quietness level of a library. This quiet and environmentally friendly construction environment not only reduces the impact on the surrounding environment, but also allows construction companies to cope more calmly under environmental pressure. Efficient construction around the clock The foundation pit is equipped with an advanced intelligent monitoring system inside the air dome, which can monitor the temperature, humidity and other environmental data inside and outside the air dome in real time, and automatically adjust the internal environment. For example, in hot summer or cold winter, the system will maintain a constant temperature within the air dome to ensure a more stable construction environment. In addition, the sealed design of the air dome effectively isolates external wind and…
