Problems solved by technology

[0003] The treatment of floods containing a large amount of sediment is a difficult water conservancy problem in the world. This is because it is difficult to intercept a large amount of fierce floods. Even if the floods containing a large amount of sediment are stored in the reservoir after the dam is built to intercept the sediment naturally, there is still a need to build a stockpile of water. Large reservoirs are sufficient to accommodate floods. However, the construction of such reservoirs requires a large investment and often takes years to build. It also needs to occupy a large amount of farmland and immigrants in the reservoir area, and more importantly, the reservoir area after completion It can only store water, and cannot cultivate fields for replanting and production
On the other hand, the flood that contains a large amount of sediment slowly deposits in the reservoir area, which will quickly reduce the volume of the reservoir area for large reservoirs, shorten the service life of the reservoir, and often require a huge amount of money to discharge sediment
And from the perspective of water conservancy, areas with large amounts of sediment-containing floods are not conducive to building dams and reservoirs.
For small reservoirs, the storage capacity determines that the flood that can accommodate a large amount of sediment cannot be allowed to slowly deposit naturally in the reservoir area, otherwise the flood will overwhelm or wash away the dam body, losing the role of flood control

Embodiment Construction

[0029] A method for water and soil separation to control water and create fields for environmental protection is:

[0030] Set water control area;

[0031] In the area of ​​flood control and land reclamation, use the slope of the terrain to find the confluence of surface runoff formed by natural rainfall, or the confluence of floods. Build the dam body, the inner and outer dam slopes, and the water control and land reclamation area surrounded by the outer dam slope and surrounding mountains for the reservoir area. The number of dam bodies is set according to the topography of the water control area, and a downstream reservoir is set on the outside of the main dam body at a suitable position lower than the ground in the reservoir area to store the water discharged from the reservoir area.

[0032] A water-soil separation structure is provided at the bottom of the reservoir area surrounded by the slope body of the inner dam and the surrounding terrain, or a water-soil separatio...

Abstract

The invention belongs to a method for water control and farmland building for environmental protection through water and soil separation and a water and soil separation structure. The method comprises the following steps of: setting a water control and farmland building area; building a dam body and internal and external dam slope body dam bodies in the water control and farmland building area, and taking the water control and farmland building area enclosed by an external dam slope body and a surrounding hill as a reservoir area; and simultaneously arranging water and soil separation structures at the inner bottom of a reservoir area enclosed by an internal dam slope body and the surrounding terrain and on the internal dam slope body to fast separate turbid water containing a lot of sediment in the reservoir area, leading separated water out of the reservoir area, storing the separated water in a downstream reservoir, and forming farmland by the precipitated sediment. The water and soil separation structure comprises a water permeable sand bed, a water permeable pipe, a water collecting channel and a water drainage channel. The invention can realize fast water and sediment separation for waterflood containing a large amount of sediment in the reservoir area, has double functions of farmland building and water storage to enable the precipitated sediment in the dam to be used for planting and production, and has the advantages of being less in investment and good in water and soil conservation, improving the ecological environment, preventing the occurrence of drought and flood, creating good conditions for the growth of crops, and increasing both production and income.

Description

technical field [0001] The invention relates to a method for separating water and soil for water control and field production and environmental protection and a separation structure thereof. Background technique [0002] my country's geographical environment determines a heavy rain, the rainwater rolls up the surface sediment and flows down, converging into a large amount of ferocious floods, destroying farmland and houses along the way, blocking the river, not only causing serious damage to human property for a long time, but also destroying the ecological environment , Water and soil were lost along the way of the flood, the rocks were exposed, the land was barren, and no grass grew. [0003] The treatment of floods containing a large amount of sediment is a difficult water conservancy problem in the world. This is because it is difficult to intercept a large amount of fierce floods. Even if the floods containing a large amount of sediment are stored in the reservoir after ...
