随着水利建设标准要求的不断提高,水利枢纽的防洪标准也在不断提高,邓州市境内小型水库多建于上世纪70年代,由于建库初期受历史条件限制,其工程质量较差,水库经过多年运行,部分设施老化破坏,其防洪标准已无法满足目前的防洪要求,对张岗等小水库进行除险加固是十分必要的。
With the continuous improvement of water conservancy construction standards and flood control standards for water conservancy hubs, the small reservoirs in Dengzhou City were mostly built in the 1970s. Due to the historical conditions at the initial stage of the construction of reservoirs, the quality of the works was rather poor. After many years of operation, some of the facilities are aged and destroyed, and the flood control standards have failed to meet the current flood control requirements. It is necessary to reinforce Zhanggang and other small reservoirs.
