【摘要】 随着近年来大型渠道引调水工程、灌区渠道改造工程的开工建设，输水渠道渠坡及底板混凝土衬砌大量采用，由于地下水对衬砌面板破坏力较大，任何局部的边坡失稳、衬砌结构的破坏都将可能影响渠道正常输水。故此，大型渠道工程永久排水设施的重要性应引起高度重视，合理有效的排水设施，可以极大减少地下水对渠道混凝土衬砌面板的破坏，保证渠道混凝土面板稳定，关系到后期输水运行的可靠安全。现场监理应加强施工过程中的工序控制，严格检查、报验制度，确保排水设施的施工质量满足设计要求。更多还原

【Abstract】 In recent years, the utilization of concrete lining for slope and floor in water transmission channels has become increasingly prevalent due to the implementation of large-scale channel water diversion projects and channel reconstruction projects in irrigation areas. The potential damage caused by groundwater to the lining panel may disrupt the smooth water transmission of the channel, as any local slope instability and structural impairment can have a detrimental impact. Therefore, the significance of permanent drainage facilities for large-scale channel projects should be highly valued. The implementation of reasonable and effective drainage facilities can significantly mitigate the detrimental impact of groundwater on the concrete lining panel of channel, thereby ensuring the stability and integrity of the channel concrete panel. It is crucial for guaranteeing the reliability and safety of later water delivery operations.The on-site supervision should enhance the process control during the construction process, implementing a rigorous inspection and evaluation system to ensure that the drainage facilities meet the design requirements.更多还原
