[0002] In the related art, the Chinese patent with the application number CN202022290953.X proposed a spatial composite utilization structure combining water conservancy dikes and farmland renovation. Based on the original farm road, the water conservancy dike project was heightened and rebuilt. Terraced fields were newly built in the areas of permanent basic farmland that might be involved on both sides of the dike, and the terraced fields were used to replace the dike slopes in the original water conservancy project without occupying the area of permanent basic farmland.

[0003] The above-mentioned related technology has the following defects: When it rains or during irrigation, the water flow at a high place cannot be effectively guided and controlled. The water flow may carry sediment and directly scour the lower terraced fields, resulting in an exacerbation of soil erosion. This will lead to a decline in soil fertility, affecting the growth and yield of crops; and the long-term scouring may cause the soil at the edge of the terraced fields to loosen and collapse, thereby destroying the integrity of the entire terraced field system; at the same time, it will also cause waste of water resources.

Horizontal drainage channels are arranged along the side away from the guide channels of the first-level terraced fields, the second-level terraced fields, and the third-level terraced fields. Vertical drainage channels for enabling water to flow from the guide channels to the horizontal drainage channels are connected between the guide channels and the horizontal drainage channels, and a first sluice is arranged between the guide channels and the vertical drainage channels.

[0007] Furthermore, the vertical drainage channels are vertically arranged between the guide channels and the horizontal drainage channels, and multiple vertical drainage channels are arranged along the newly built dike.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The technical solution of the present application will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts belong to the scope of protection of the present application.

[0020] An embodiment of the present application discloses a spatial composite utilization structure combining a water conservancy dike and farmland renovation. Referring to Figure 1 and Figure 2 , a spatial composite utilization structure combining a water conservancy dike and farmland renovation includes a newly built dike 1 and multiple terraced fields. The multiple terraced fields are specifically the first-level terraced field 2, the second-level terraced field 3, and the third-level terraced field 4 that are simultaneously arranged on both sides of the newly built dike 1. Guide canals 11 are arranged along both sides of the top of the newly built dike 1. Specifically, the guide canals 11 are of concrete structure and are connected to irrigation systems such as surrounding pumping stations. Horizontal drainage canals 6 are horizontally arranged along the side of the first-level terraced field 2, the second-level terraced field 3, and the third-level terraced field 4 that is far from the guide canals 11. Specifically, the horizontal drainage canals 6 are of concrete structure. A longitudinal drainage canal 7 for allowing water to flow from the guide canals 11 to the horizontal drainage canals 6 is connected between the guide canals 11 and the horizontal drainage canals 6. Specifically, the longitudinal drainage canal 7 is of concrete structure, and a first sluice 111 is arranged between the guide canals 11 and the longitudinal drainage canal 7.

[0021] In this way, when irrigating, the first sluice 111 is opened, and the water in the guide canals 11 flows through the longitudinal drainage canal 7 to reach the horizontal drainage canals 6 of the first-level terraced field 2, the horizontal drainage canals 6 of the second-level terraced field 3, and the horizontal drainage canals 6 of the third-level terraced field 4 in sequence; when it rains, the accumulated water in the first-level terraced field 2, the second-level terraced field 3, and the third-level terraced field 4 is respectively drained through the horizontal drainage canals 6 of the first-level terraced field 2, the horizontal drainage canals 6 of the second-level terraced field 3, and the horizontal drainage canals 6 of the third-level terraced field 4, avoiding the situation where the water flow at a high place is not effectively guided and controlled, resulting in a large amount of sediment being directly washed to the lower terraced fields, exacerbating soil erosion and at the same time causing a decline in soil fertility and affecting the yield of crops.

[0022] Specifically, referring to Figure 1 and Figure 2 , the longitudinal drainage canal 7 is vertically arranged between the guide canals 11 and the horizontal drainage canals 6, and multiple longitudinal drainage canals 7 are arranged along the newly built dike, reducing the waste of water resources while facilitating irrigation.

[0023] And referring to Figure 2 and Figure 3 , a catch basin 8 is arranged at the intersection of the horizontal drainage canal 6 and the longitudinal drainage canal 7. Specifically, the catch basin 8 is of concrete structure. The setting of the catch basin 8 can effectively relieve the impact force of the water flow flowing downward from a high place, and at the same time can also play a role in balancing the water flow.

[0024] A water pump 81 connected to the surrounding pumping station is provided in the catch basin 8 that is close to the surrounding pumping station and located within the third-level terraced field 4. In this way, when the remaining irrigation water flows back to the catch basin 8 with the water pump 81 through the lateral drainage channel 6 and the longitudinal drainage channel 7, the water pump 81 can be turned on to pump the returned irrigation water back to the surrounding pumping station, realizing the efficient recycling of water resources.

[0025] Furthermore, referring to Figure 2 and Figure 3 , a second sluice gate 82 is provided at the connection between the catch basin 8 and the longitudinal drainage channel 7, and a third sluice gate 83 is provided at the connection between the catch basin 8 and the lateral drainage channel 6. When needed, the direction and flow rate of the irrigation water can be controlled by closing the second sluice gate 82 and the third sluice gate 83, ensuring the uniform distribution of the irrigation water to meet the irrigation requirements of different areas of the first-level terraced field 2, the second-level terraced field 3, and the third-level terraced field 4. At the same time, the irrigation water can be effectively utilized, reducing water resource waste.

[0026] In addition, screens 84 are provided at the connection parts between the catch basin 8 and the lateral drainage channel 6 and the longitudinal drainage channel 7, which can effectively filter out the sundries in the drainage channels. While facilitating the cleaning of the sundries in the water, it can also effectively prevent the lateral drainage channel 6 and the longitudinal drainage channel 7 from being blocked by sundries.

[0027] Meanwhile, two slots 841 with opposite opening directions are provided at the connection part between the catch basin 8 and the lateral drainage channel 6 or the longitudinal drainage channel 7, and the screen 84 is inserted into the two opposite slots 841 to facilitate the installation of the screen 84 and the replacement of the damaged screen 84.

[0028] The implementation principle of the spatial composite utilization structure combining a water conservancy dike and farmland renovation in the embodiment of the present application is as follows:

[0029] When irrigating, the first sluice gate 111 is opened, and the water flow in the water diversion channel 11 reaches the lateral drainage channels 6 of the first-level terraced field 2, the lateral drainage channels 6 of the second-level terraced field 3, and the lateral drainage channels 6 of the third-level terraced field 4 in sequence through the longitudinal drainage channel 7, ensuring the uniform distribution of the irrigation water to meet the irrigation requirements of different fields, effectively utilizing the irrigation water, reducing water resource waste, and at the same time preventing the water flow on the high terraced fields from directly scouring the low terraced fields, resulting in the aggravation of soil erosion. When it rains, the accumulated water in the first-level terraced field 2, the second-level terraced field 3, and the third-level terraced field 4 is drained through the lateral drainage channels 6 of the first-level terraced field 2, the lateral drainage channels 6 of the second-level terraced field 3, and the lateral drainage channels 6 of the third-level terraced field 4 respectively, avoiding the situation where the water flow at a high place is not effectively guided and controlled, carrying a large amount of sediment and directly scouring the low terraced fields, resulting in the aggravation of soil erosion and the decline of soil fertility, affecting the crop yield.
