Choosing Between Inflatable Rubber Dam and Air‑Shield Dam: A Clear Guide to Cost and Service‑Life Comparison
In river landscape water storage, watershed ecological restoration, flood‑control regulation and water‑environment improvement projects, inflatable rubber dams and air‑shield dams are two widely‑adopted low‑carbon flexible water‑retaining facilities. Compared with traditional concrete sluice‑gates and dams, both types feature less civil‑engineering work, shorter construction periods, unobstructed flood discharge and minor disturbance to river ecology. They are well‑suited for green water‑conservancy construction and long‑term watershed governance under the carbon‑neutrality initiative. Nevertheless, notable differences exist in structural characteristics, service life, construction cost, operation‑maintenance requirements and operating performance in practical engineering applications. Selecting the appropriate dam type according to project working conditions is critical to controlling project costs, lowering operation‑and‑maintenance energy consumption and guaranteeing long‑term wate
