Abstract

The invention relates to a developing and governing method for a sandy wide channel canal / shoal / pool. A narrow river channel is formed by two main dikes (new flood dikes) which are constructed between the prior flood dikes at two sides of a sandy channel segment along the riverway trend, and large dams are constructed at the upstream and the downstream. A water supply and sand diversion canal is constructed at the inside or outside of at least one of the main dikes in the narrow river channel. A conveyance and navigation canal is constructed outside one or two sides of the narrow river channel. The conveyance and navigation canal is adjacent to the water supply and sand diversion canal or the conveyance and navigation canal, or the conveyance and navigation canal is a split type. The bottomland and the pool surrounded by the diking are changed from the shoal area between the main dike or canal dike and the prior flood dikes. The bottomland can be a permanent site for living, production, construction and development. The long-term reserved pool is capable of storing water resource and supplying water in non-flood season, storing floodwater and replenishing dryness in flood season, and detaining and storing the flood. The developing and governing method for the sandy wide channel canal / shoal / pool effectively prevents from flood, treats and uses slit, ensures the security in flood prevention, and supplies enough rinsing water source; the water service cost is low, and the method is capable of developing and utilizing the resources such as hydraulic power, shipping, and tourism, etc. in the channel segment, and the method has a positive meaning in improving environment.

Description

1. Technical field:

[0001] The invention relates to a method for development and management of sandy river sections in the technical field of water conservancy engineering, in particular to a method for development and management of canal channels and beach reservoirs in wide sandy river sections. 2. Background technology:

[0002] In 1855, the lower reaches of the Yellow River diverted at the Tongwaxiang breach, taking the Daqing River into the Bohai Sea in Kenli County, Shandong Province to form the current channel. The channel is 878km long, with a drop of about 118m. The river channel is wide at the top and narrow at the bottom, the gradient is steep at the top and slow at the bottom, and the flood discharge capacity is large at the top and small at the bottom. There are 3544km of beaches in the river 2 , Accounting for 84% of the river area, more than 1.8 million people live in Henan and Shandong provinces. Over the past 150 years, when the Yellow River was still a na...

Examples

Embodiment 1

[0054] Embodiment one: see figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 , a method for the development and management of channel channels and beach reservoirs in wide sandy river sections. The original flood control dike 9 is built at a certain width on both sides of the sandy river section, and two main dikes 3 are built along the direction of the river in the center of the original flood control dike 9 to form a narrow River channel 4, building dams 1 and 2 on the upper and lower reaches of the sandy river section, gate groups D1 and D2 are respectively provided at the intersections of the narrow river channel 4 and the upper and lower dams 1 and 2, A water supply and sand diversion canal 12 is built on the outside of each main dike 3, and a single water supply and sand diversion canal 12 shares a main embankment 3 with the narrow channel 4,...

Embodiment 2

[0063] Embodiment two: see Figure 15 , Figure 16 , Figure 17 , Figure 18 , Figure 19 , numbering is identical with embodiment one, and meaning is the same, does not repeat, and difference is: water delivery and shipping canal 7 and narrow river channel 4 are split type or partial split type, and water delivery and navigation canal 7 has both sides dikes (shipping dikes) 6. There is a part of reserved area 26 between the shipping embankment 6 on one side and the water and sand diversion channel embankment 13. This embodiment is mainly suitable for river courses that may bend and turn due to the terrain, but the water delivery and shipping channel 7 should be kept as flat as possible. It is advisable to be straight, so the water delivery and shipping canal 7 is not necessarily completely parallel to the narrow river channel 4, that is, the water delivery and navigation canal 7 can be kept straight with the narrow river channel 4 as a whole, and partially adjacent to the ...

Embodiment 3

[0065] Embodiment three: the figure is not drawn, meaning is basically the same as embodiment one, and the similarities are not repeated. The difference is that the water supply and sand diversion channel is built on the inside of the two main embankments of the narrow river channel, so that the water delivery and navigation channel and the narrow river channel A common embankment.
