(6) Water environmental protection

(6) Water environmental protection measures. The mitigation measures in the design period are that the construction of farmland irrigation and drainage facilities must be completed before subgrade construction, and the design scale should not be lower than the current level, and the flood discharge area should meet its maximum flood discharge standard. At the same time, arrange the construction period reasonably, and complete the irrigation canal before the irrigation period; The spillway system was completed before the flood arrived. At the same time, this project has passed through many water sources. In order to prevent pollution to water sources, emergency ditches and sewage storage tanks are set on both sides of the subgrade of water sources, ceramic waterstops are set on the edge of roads, and comprehensive drainage systems are set on bridges to avoid polluting water bodies, oil stains, dangerous goods, etc. from seeping into the ground during operation and causing pollution to water sources.
