Multifunctional flooding irrigation reservoir system and construction method

Abstract

The invention relates to the technical field of water resource protection, and discloses a multifunctional flooding irrigation reservoir system and a construction method. The first function is irrigation, water flows in all water delivery lines, power does not need to be provided, the cost of water for irrigation is reduced, rain in a planting region can flow to one or more planting regions whichdo not have rain and are same in altitude through the water delivery lines, the water content of a mountain is reduced, occurrence of landslide and debris flow in the rainstorm period is reduced, theriver reserve irrigation water volume is increased, the amount of water seeping into the ground is increased, the underground water level reserve and emergency drought-resistance water source is improved, the manufacturing cost is low, a reservoir has the function of automatically cleaning away silt to protect the reservoir capacity, the maintenance cost is low, distribution is uniform, the quantity is large, more villages combine the irrigation system with tourism, aquaculture, livestock farming and poultry framing, the construction and maintenance cost of the irrigation is shared, and the reservoir can be constructed to achieve the purposes that water can overflow the reservoir, the reservoir cannot be damaged, and silted sediment can be washed away. Multiple layers of planting regions are divided according to different altitudes, and water can automatically flow to the planting regions low in altitude from the planting regions high in altitude. Water in multiple planting regions same in altitude can flow automatically and mutually. The altitude in the independent planting region is the same, and water can mutually and automatically flow in the delivery lines.

Description

Technical field [0001] The invention relates to the technical field of water resources protection, and in particular to a multifunctional flood irrigation reservoir system and a construction method. Background technique [0002] Reservoir is a widely used engineering measure for flood control and irrigation in my country. The geological conditions on the river are surveyed to build a reservoir at a location suitable for dam construction. The reservoir capacity is used to store floods and reduce peak flow. It has the functions of flood discharge and flood storage, thereby improving the navigation performance of the river and increasing the number of floods. In order to increase power generation, reduce flood disasters, and ensure irrigation water, in order to increase power generation, reduce flood disasters on a larger scale, and ensure more irrigation water, the reservoir capacity and dam height are becoming larger and larger, and the irrigation canals supporting the reservoi...

Problems solved by technology

[0002] Reservoirs are widely used engineering measures for flood control and irrigation in China. The geological conditions on the river channel are surveyed and the location of the dam is suitable for the construction of the reservoir. The reservoir capacity is used to store the flood, reduce the peak flow of the flood, and have the functions of flood discharge and flood storage, so as to improve the navigation performance of the river channel and increase the In order to increase power generation, reduce flood disasters and ensure irrigation water, the storage capacity of the reservoir and the height of the dam body will become larger and larger, and the irrigation canals supporting the reservoir will be larger and larger. The water lifting stations on the irrigation canal are getting bigger and bigger and more and more, and the power consumption of the water lifting stations is increasing. Large and super large reservoirs guarantee the storage of irrigation water, but increase the price of irrigation water and the construction cost of irrigation facilities. There is water available but the construction cost of irrigation facilities cannot be afforded. The construction cost of irrigation facilities has been solved. The construction of irrigation facilities has been completed, but farmers cannot afford the water and electricity costs for irrigation. Now the reservoir system and construction method on the river are not functionally irrigation The first function is that the supporting irrigation canals and water lifting stations are greatly restricted by geographical conditions in irrigation, especially the impact of altitude drop is the greatest. In plain areas, the altitude drop is small and the water and electricity costs for irrigation are less. The water and electricity costs for small irrigation vary from big to small, and the impact is medium. In mountainous areas, the altitude difference is the largest. The highest irrigation water and electricity costs are also the most influential. In some areas, the altitude difference is too large. The proportion of irrigation water and electricity costs to farming income is too high, and the irrigation function is lost. Application No. 2012104453124 Publication A point-type reservoir can be used in any place where there is rainfall. It can automatically store precipitation and serve as a water source during drought. However, after the stored water reaches the storage capacity, the excess rainfall cannot be transported to areas without rainfall for irrigation. Application No. 2015104325628 discloses a hilly mountainous reservoir system and its construction method. In the ravine and hillside surface of the existing reservoir catchment area, a water storage unit system is built to collect rainwater during heavy rains, increasing the soil on the ravine surface and the hillside surface. The amount of water infiltration in the soil can reduce the storage pressure of the reservoir, delay the time when the rainwater reaches the reservoir, and reduce the amount of rainwater entering the reservoir. However, the water cannot but enter the reservoir and be transported to areas without rainfall, in the soil on the surface of ravines and on the surface of hillsides The increase in water seepage will induce landslides and debris flows. Under the premise of satisfying the growth of mountain plants, the smaller the water seepage in the soil on the surface of the valley and the soil on the surface of the hillside, the stronger the mountain
