Anti-freezing device for concrete joint water stop structure of concrete faced rockfill dam in cold region
The invention belongs to the technical field of anti-freezing and deicing of water stop structures of concrete faced rockfill dams in cold regions, and particularly relates to an anti-freezing device for a water stop structure of a concrete joint of a concrete faced rockfill dam in cold regions, which comprises an electric tracing band, an electric tracing band fixing plate, a heat insulation plate and an arc-shaped metal cover plate, the electric tracing band is wound on the electric tracing band fixing plate; the arc-shaped metal cover plate is arranged above the electric tracing band and is used for providing physical protection for the heating unit and facilitating uniform heat transfer of the electric tracing band after heating; the heat insulation plate is arranged below the electric tracing band and used for isolating the electric tracing band from the water stop structure, and the phenomenon that organic materials in the water stop structure are aged and fail due to high temperature is avoided. According to the invention, the electric heat tracing structure is utilized to realize active deicing and anti-freezing functions; meanwhile, the danger and difficulty degree of concrete faced rockfill dam construction are comprehensively considered, the anti-freezing structure and the construction process are optimized, consumed manpower and material resources are reduced, and the danger and difficulty degree of construction are reduced, so that the long-term reliable and stable deicing effect is provided for the water stopping structure.
本发明属于寒区面板坝止水结构防冻除冰技术领域，具体涉及一种寒区面板坝混凝土接缝止水结构抗冻装置，包括电伴热带、电伴热带固定板、隔热板和圆弧形金属盖板；电伴热带缠绕安装在电伴热带固定板上；圆弧形金属盖板设置在电伴热带的上方，用于为发热单元提供物理保护以及方便电伴热带发热后的均匀传热；隔热板设置在电伴热带的下方，用于隔绝电伴热带与止水结构，避免止水结构中的有机材料因高温出现老化失效。本发明利用电伴热结构实现主动除冰防冻功能；同时综合考虑到对于面板坝施工的危险性和困难程度，优化防冻结构和施工过程，减少耗费的人力物力，降低施工的危险性和困难程度，从而为止水结构提供长期性能可靠、稳定的除冰效果。
