Embodiment 1

[0018] This embodiment is a design method of a water delivery system, the design flow chart is shown in figure 1 shown. The method described in this embodiment has two basic elements: the selection of regulation and storage nodes and the determination of engineering parameters.

[0019] At the end of the water diversion project, there are inconsistencies and out-of-synchronism in the time and flow of incoming water and water demand in the water distribution section. Project accidents occur when there is a surplus of water in the pipe network or channels at the distribution interface section; on the contrary, too little water in the water transfer section and more water in the water distribution section will lead to a decrease in the water supply guarantee rate of the project and cannot meet the expected requirements. Based on this, in the transition process between the water transfer section and the water distribution section, setting up reasonable regulation and storage node...

Embodiment 2

[0035] This embodiment is an improvement of the first embodiment, and it is a refinement of the first embodiment on the analysis of the spatial relationship between the terrain elevation and the regulation and storage nodes. The analysis of the spatial relationship between the altitude and the regulation and storage nodes described in this embodiment is based on the GIS platform and DEM.

[0036] (1) Elevation analysis of regulation and storage nodes

[0037] The water level at the outlet of Huangchigou in the water receiving area of ​​the water diversion project from Han to Wei is 510m. Therefore, considering the operation cost in the process of water transfer, the altitude of each storage node should not be too high. With the help of the GIS platform, the DEM data is used for analysis, and the average altitude of the potential storage nodes is automatically screened to exclude the storage nodes whose average altitude is too high.

[0038] (2) Analysis of node spatial relati...

Embodiment 3

[0042] This embodiment is an improvement of the first embodiment, and it is a refinement of the embodiment regarding the address selection of the regulation and storage nodes. The regulation and storage node in the step of selecting the location of the regulation and storage node described in this embodiment adopts one of centralized regulation and storage nodes or decentralized regulation and storage nodes.

[0043] (1) Arrangement of centralized regulation and storage nodes:

[0044] This scheme is more suitable for establishing large-scale reservoirs, establishing storage nodes, and then transporting them to water distribution nodes in various water receiving areas through pumping stations. The project of this scheme is relatively simple, the technical difficulty is not great, and the operation scheduling is simple and easy. However, it is more difficult to use in densely populated developed areas and requires more immigrants. Affected by the terrain, it is usually diffic...

Abstract

The invention relates to a design method of a water conveyance system. The steps comprise terrain analysis, regulation and storage node site selection, regulation and storage node analysis, engineering parameter confirmation, and water distribution network design parameter selection. The terrain analysis and the regulation and storage node analysis are adopted, the safety and social factors of a regulation and storage node are fully considered, and the design technology problem and related social and environment protection problems of the tail end of a water transfer project are solved to the maximum degree. Meanwhile, a supply and demand balance model is established for solving the contradiction among water transfer, water supply and water use, a roughness factor and the design elements of a water supply network are fully considered, and the regularization process of water transfer project design is achieved.

Description

technical field [0001] The invention relates to a design method of a water delivery system, which is a design method of a large-scale hydraulic engineering project and a design method of a water receiving terminal of a water diversion project. Background technique [0002] For northern China, where water resources are scarce, it is a good choice to transfer the abundant water resources in the south to the arid and rainless areas through hydraulic engineering. But how to store and make full use of the transferred water source is a problem that needs to be solved, which is a systematic project. [0003] First of all, it is necessary to consider how to make full use of the existing natural and artificial water networks in the receiving area to store incoming water, and establish a water storage system with minimal engineering investment. The water storage capacity should not be too low, in order to prevent water abandonment, serious operation accidents will occur, resulting in...
