Against the backdrop of growing demands for quality improvement and efficiency enhancement in water conservancy engineering, air-shield dams have quickly become an industry highlight due to their core advantages of high efficiency, intelligence and eco-friendliness. Their construction technologies and standardized solutions have also attracted widespread attention from all sectors. With years of in-depth expertise in water conservancy equipment and rich practical engineering experience, we hereby conduct a comprehensive breakdown of the entire standardized construction process for air-shield dams. Through professional interpretation, we break down technical barriers and deliver practical, implementable guidelines for practitioners and project demanders, ensuring the safe and efficient delivery of every water conservancy project.
Foundation treatment is the fundamental prerequisite for the safe and stable operation of air-shield dams, as well as the top priority in construction. In the early construction stage, we complete precise surveying and setting out to define the construction boundary scope thoroughly. We then fully remove debris, broken concrete and sharp protrusions from the dam foundation, clean the base surface with high-pressure water, and drain all accumulated water to ensure the foundation meets dry and solid construction standards. Meanwhile, we implement steel bar planting and reinforcement for the original foundation. Professional steel bar detectors are used to accurately locate existing steel bars to avoid interference during reinforcement work. All anchor bolts strictly comply with industry standards in pull-out resistance, laying a solid foundation for subsequent dam installation.
Modular construction is our core advantage in air-shield dam projects, which effectively improves construction efficiency and shortens the construction period. Key components including alloy shield plates, pressure-resistant airbags and intelligent control systems are prefabricated in factories in accordance with unified standards. After being delivered to the construction site, they are assembled following standardized procedures. We strictly adhere to the standardized workflow of "survey positioning — component placement — anchoring fixation — pressure testing and inspection". With mechanical assistance, the installation of a single-span dam can be completed within several days, effectively reducing adverse impacts of weather and other external factors on the construction schedule.
After installation, comprehensive equipment commissioning is carried out to guarantee the intelligent and compliant operation of the air-shield dam. We install air compressors, intelligent control cabinets, water level sensors and pressure sensors in a standardized manner, with precise connection of inflation and deflation pipelines. Graded inflation pressure testing is adopted, with each pressure level maintained for 30 minutes to fully inspect the sealing performance of the dam and eliminate leakage risks. Upon successful commissioning, the dam supports remote control, automatic water level adjustment and rapid lifting, which greatly enhances the intelligent operation level of the project and reduces manual operation and maintenance costs.
We always prioritize construction quality and safety, and implement standardized management throughout the whole process. During construction, a three-inspection system — initial inspection by construction teams, re-inspection by technical staff, and final inspection by quality supervisors — is strictly enforced. Full-process supervision is applied to material incoming inspection, key construction procedures and concealed works acceptance, ensuring a 100% one-time acceptance rate for unit projects. In addition, we formulate complete construction safety specifications and special emergency plans for flood seasons, fully protecting the personal safety of construction personnel and the overall quality of the project.
In conclusion, our air-shield dam construction solutions integrate high efficiency, safety and intelligence. Every procedure from foundation treatment to equipment commissioning strictly follows industry standards and technical specifications, balancing project quality and construction efficiency.
