In the field of water conservancy projects, continuously innovating technologies and structures have brought new possibilities for water resource management and utilization. As a new type of water-retaining structure, the air shield dam has attracted much attention in recent years. Among its many advantages, the characteristics of simple structure and easy installation are particularly prominent, which are profoundly changing the construction mode of water conservancy projects. This structural advantage is not just empty talk, but is practically reflected in every link of engineering practice. The structural design of the air shield dam is unique, mainly composed of shield plates, inflatable airbags and control systems. This unitized and modular structural mode enables it to show unparalleled advantages in the construction process. The fact that no large-scale construction equipment is needed means that the construction of the air shield dam can still proceed smoothly in complex environments such as limited construction sites and inconvenient transportation. Different from traditional water conservancy projects that often require large lifting equipment and professional excavating machinery, the installation of the air shield dam relies more on manual cooperation, which greatly reduces the demand for special equipment. This feature directly leads to significant savings in human, material and financial resources. In terms of human resources, it reduces the dependence on professional equipment operators. Ordinary construction workers can participate in the installation work after simple training, which reduces labor costs and at the same time reduces safety risks caused by improper equipment operation. In terms of material resources, there is no need to deploy large-scale equipment, avoiding a series of tedious tasks such as equipment transportation, leasing and maintenance, thus reducing the investment in material resources. In terms of financial resources, the reduction in equipment use costs, the decrease in labor costs and the improvement in construction efficiency have all led to a substantial drop in the overall construction cost. According to relevant data statistics, compared with traditional dam types, the air shield dam can save about 50% of the cost during the construction process. The short construction period is also a major highlight of the air shield dam. The construction of traditional water conservancy projects often takes a long time, and each link, from the preliminary equipment preparation and site leveling to the main structure construction, is time-consuming. However, due to its simple structure and convenient installation, all components of the air shield dam are prefabricated and can be quickly assembled after being transported to the site. Taking small and medium-sized air shield dam projects as an example, it only takes 5 months from the start of construction to completion, while traditional dam projects of the same scale take at least about 15 months. The significantly shortened construction period of the air shield dam not only enables the water conservancy project to be put into use faster, playing its due functions such as flood control, irrigation and water supply, but also reduces the impact on the surrounding environment and residents' lives during the project construction period. In addition, the later maintenance of the air shield dam is simpler due to its modular design. When a certain module has a problem, it can be directly replaced or repaired without large-scale overhaul of the entire dam, which reduces maintenance costs and difficulty. With its advantages of simple structure, easy installation and short construction period, the air shield dam has shown strong competitiveness in water conservancy project construction. With the continuous promotion and application of the technology, it is believed that the air shield dam will play a more important role in the field of water conservancy projects in the future, providing a solid guarantee for the rational development and utilization of water resources.
