城市综合管廊和海绵城市建设,其载体都需要地下混凝土箱涵、混凝土雨水集水沟、蓄水槽、钢筋混凝土排水管来承担,而工厂化生产的高强度、抗渗漏、耐久性好、成本低、质量优、便于安装的的预应力钢筋混凝土制品配套产品,符合国家有关环保、低碳、节能、高效的绿色建材产业发展政策。文章详述了适宜管廊和海绵城市建设的工厂化生产的各种预应力预制混凝土新产品的结构特点、性能和技术优势,以及与传统产品对比的经济性和可行性及研究结果。
Urban integrated pipe gallery and sponge city construction, the carrier needs underground concrete box culvert, concrete rainwater catchment, water storage tank, reinforced concrete drainage pipe to bear, and factory production of high strength, anti-leakage, durability, Low cost, high quality, easy to install prestressed reinforced concrete products supporting products, in line with national environmental protection, low carbon, energy saving, efficient green building materials industry development policy. The article details the structural features, performance and technical advantages of various prefabricated precast concrete products suitable for industrialized production of pipe galleries and sponges in urban construction, as well as the economics and feasibility of the comparison with traditional products and the results of the research.
