Research on the Integration of Structural Design of Urban Irrigation Buildings and Water Saving Technology Based on the Concept of Sustainability

Abstract

In the process of urban development, the shortage of water resources has brought obstacles to urban development, and it is urgent to realize the structural innovation design of urban irrigation buildings and the effective application of water-saving technical measures. This paper establishes a structural system of urban irrigation buildings by combining the concept of sustainable development with highly efficient water-saving irrigation technology as an entry point. For the comprehensive benefits of water saving under this structural design, the evaluation index system of water saving benefits of irrigation buildings is designed, and the weights of the evaluation indexes are solved by the improved entropy weighting method. Combining the improved entropy weight method with the close value method, an evaluation model for the comprehensive benefits of water conservation of urban irrigation building structures was established, and the relevant factors affecting the structural design and water conservation benefits of urban irrigation buildings were analyzed through the obstacle degree factor model. The weight of each evaluation index of water saving benefits of urban irrigation building structures varies greatly, among which the weight of social benefits accounts for the largest proportion of 0.2049. After the implementation of the irrigation building structure system in the sample cities, their comprehensive benefits of water saving showed an overall increasing trend during 2015-2023. The social and economic benefits become important factors hindering the deep integration of urban irrigation building structure design and water-saving technology. Therefore, further development of high-standard urban irrigation building structure design, combined with sustainability impact assessment and increased investment in irrigation building structure renovation, is needed to provide a guarantee for realizing the improvement of water-saving benefits of urban irrigation building structures.
