68岁老水闸冬季焕新

Core Viewpoint - The article highlights the ongoing construction of the Liuhua Dam reinforcement project in Liaoyang, which is the largest water gate project in the province, emphasizing the urgency and innovative methods employed to ensure timely completion despite harsh winter conditions [2][3][4]. Group 1: Project Overview - The Liuhua Dam reinforcement project is the largest key project in the province's water gate category, with construction having started on October 30, 2025 [2]. - The project aims to ensure that the dam can store water by the end of March and meet irrigation needs for downstream farmland by the end of April [2][3]. - The original dam, built in 1958, has deteriorated significantly, necessitating its reconstruction to enhance irrigation capabilities and improve water resource management in the region [4]. Group 2: Construction Techniques - A unique construction method involving a heated enclosure has been implemented to facilitate winter construction, allowing for optimal conditions for concrete pouring [3]. - The enclosure uses a combination of "anti-freeze plastic and insulation blankets," with heating provided by stoves and diesel generators [3]. - Additional measures include heating raw materials, using warm water for mixing, and adding early-strength and anti-freezing agents to ensure concrete quality during winter [3]. Group 3: Future Developments - The renovated Liuhua Dam will feature a "digital brain" for real-time monitoring of water levels, flow rates, and structural integrity, enabling automated control of the gates [6]. - This modernization is expected to significantly enhance the management and efficiency of water resources in the region [6].
