Embodiment Construction
[0028] A method for constructing a lateral seepage-overflow system in a sub-dam area of a floodplain river, including a siphon water intake system, a river bank lateral seepage system, and a river bank overflow system.
[0029] S1: Build a siphon water intake system, siphon the upstream water of the dam to the river beach on both sides of the dam through the siphon device;
[0030] S2: Construct the side seepage system of the river beach, excavate the side seepage ditch in the river beach, the side seepage ditch is parallel to the flow direction, and the side seepage ditch extends from the river beach slope to the water surface, including the first level side seepage ditch, the second level side seepage ditch, and the third level side seepage ditch Seepage ditch... Nth level side seepage ditch;
[0031] S3: Construct a river beach overflow system. The interval between adjacent side seepage ditches is the flood area. Pebbles are placed in the flood area, and emergent plants a...
