Embodiment 1
[0020] Seasonal flood standard area 1000km 2 Peak flow is 500m 3 For floods below / s, a tree-like three-level utilization method is established, and the same level can be used multiple times, and each level can be used once. Specific reference figure 2 :
[0021] First-level utilization mode: the interception dam has 6 rows of interception piers, the first row is composed of 6 interception piers, and the number of subsequent interception piers decreases in turn; build a reservoir and a silt area under the last row of interception piers;
[0022] Two-level utilization mode: the interception dam has 5 interception piers respectively, the first row is composed of 5 interception piers, and the number of interception piers in the subsequent rows decreases in turn; build a reservoir and a silt area under the last row of interception piers;
[0023] Three-level utilization mode: the interception dam has 4 rows of interception piers, the first row is composed of 4 interception pie...
Embodiment 2
[0029] Seasonal flood standard area 1000km 2 The flood peak flow is 500~1000m 3 / s flood, establish a tree-like four-level utilization method, and the same level can be used multiple times, and each level can be used once. Specific reference image 3 :
[0030] First-level utilization mode: the intercepting dam has 8 rows of intercepting piers, the first row is composed of 8 intercepting piers, and the number of subsequent intercepting piers decreases in turn; build a reservoir and a silt area under the last row of intercepting piers;
[0031] Secondary utilization mode: the interception dam has 6 rows of interception piers, the first row is composed of 6 interception piers, and the number of subsequent interception piers decreases in turn; build a reservoir and silt area under the last row of interception piers;
[0032] Secondary utilization mode: the intercepting dam has 5 rows of intercepting piers, the first row is composed of 5 intercepting piers, and the number of su...
