| 首先是根据洪水计算和调洪演算得出应泄流量确定排水系统类型和尺寸（计算的泄流量大的用排水井（框架式、窗口式）—涵管（或隧洞），稍小的用斜槽—排水管（还要看地形合不合适），如果确定选用排水井，那高度直径之类的，当然根据实际需要结合图集；） First of all, the type and size of drainage system (drainage well (frame type, window type) - culvert pipe (or tunnel) for large discharge, and chute drainage pipe (depending on the terrain) for small discharge) are determined according to the flood calculation and flood regulation routing calculation. If the drainage well is selected, the height and diameter are determined, of course, according to the actual needs combined with the atlas; ) 放置距离…这个，具体放哪合适得看你的地形图，反正得留出干滩长度，满足澄清距离。 Place distance... This, which is suitable depends on your topographic map, anyway, you need to set aside the length of dry beach to meet the clarification distance. 进水构筑物为多个排水井时， 第一个井要满足初期使用时的澄清距离要求且能尽快排出澄清水，后期排水井位置逐步增高，且要使井筒有一定的高度重叠（一般1m左右） When the intake structure is multiple drainage wells, the first well shall meet the requirements of clarification distance in the initial use and clear water shall be discharged as soon as possible. In the later stage, the position of drainage wells shall be gradually increased, and the shaft shall have a certain height of overlap (generally about 1 m). |
