水利是农业的命脉,灌区为河南的农业生产、粮食供给提供了坚固的灌溉用水保障,为河南作为中国粮食核心区做出了重要贡献。但河南省灌区多为上世纪六七十年代建设,年久失修、淤积严重、效益锐减。近年来,党和政府加大水利事业的投入,对病险水利工程及设施、设备进行维修和除险加固,灌区续建配套与节水改造项目也在其中。随着灌区改造项目的进展,许多工程受农作物灌溉季节影响及施工工期制约,冬季施工不可避免。文章结合作者工作经验,根据灌区冬季施工特点,分析探讨灌区续建配套与节水改造工程项目混凝土冬季施工保温措施。
Water conservancy is the lifeblood of agriculture. Irrigation areas provide solid irrigation water security for Henan’s agricultural production and food supply and make an important contribution to Henan as the core area of China’s grain. However, most irrigation areas in Henan Province were built in the 1960s and 1970s, and they were disrepair after a long period of sedimentation. In recent years, the party and government have increased investment in water conservancy projects, repairing and reinforcing hazardous disease water conservancy projects and facilities and equipment, as well as the project of rebuilding and water-saving projects in the irrigation districts. With the progress of the irrigation area reconstruction project, many projects are affected by the crop irrigation season and construction period constraints, and winter construction is inevitable. According to the author’s work experience, according to the characteristics of winter construction in irrigation district, this paper analyzes the winter construction insulation measures of concrete construction in the Irrigation District.
