Cost-Benefit Analysis: Why Rubber Dams Save More Engineering Budget
In modern hydraulic engineering bidding and construction, cost control and long-term benefit evaluation are the core factors that engineering purchasers and construction units focus on. Many traditional water retaining facilities have low initial investment on the surface, but they have high maintenance costs, short service life and poor adaptability, resulting in extremely high comprehensive cost in the whole life cycle. Through systematic cost-benefit analysis, inflatable rubber dams have become the most economical and cost-effective hydraulic water control facility in various engineering scenarios, which can effectively save the overall budget of water conservancy projects. First of all, in terms of initial construction cost, rubber dams adopt modular industrial production, with standardized finished products and supporting accessories, no complex on-site pouring and building construction procedures, and the construction cycle is only 1/3 of that of traditional concrete dams. It saves a lot of construction materials, mechanical equipment investment and manual construction costs, and the overall initial investment is far lower than traditional rigid dams. Secondly, in terms of transportation and installation costs, rubber dams can be folded and transported in bulk, with low transportation volume and convenient handling, no need for large-scale hoisting equipment, which greatly saves transportation and construction auxiliary costs. In terms of later operation and maintenance, the advantages of rubber dams are more prominent. The high-strength composite rubber material has super anti-aging, anti-corrosion and anti-wear performance, which can resist long-term water flow scouring, floating object impact and environmental erosion, and will not have structural damage and water leakage failure in 10-15 years of normal use. It does not need regular reinforcement, repair and anti-corrosion treatment like concrete and steel dams, and the annual maintenance cost is almost negligible. In addition, rubber dams have strong reuse value. Portable inflatable rubber dams can be disassembled, folded and stored after the completion of temporary engineering projects, and reused in subsequent different construction scenarios, realizing repeated utilization of resources and further reducing engineering unit cost. From the perspective of whole life cycle benefit, rubber dams have the advantages of low initial investment, low maintenance cost, long service life and reusable performance, which can maximize the economic benefit of hydraulic engineering and is the preferred cost-saving solution for modern water conservancy construction
