Description

Technical fields:

[0001] This invention relates to the field of saline-alkali land improvement technology, and in particular to a greening improvement device and method for high salinity slope protection in the Hetao Irrigation Area. Background technology:

[0002] Northwest China is located in the mid-temperate semi-arid zone, characterized by year-round drought and low rainfall, high evaporation rates, and high soil salinity. Meanwhile, numerous irrigation canals exist within abandoned saline-alkali land to improve this land. Introducing high-quality freshwater resources could significantly optimize industrial and agricultural production in the region, which suffers from freshwater scarcity. However, it also brings considerable inconvenience to local residents, ultimately impacting the region's long-term development.

[0003] Therefore, the construction of the Hetao Irrigation Area is an important measure for the sustained and positive development of the region's economy and society. However, the saline-alkali soil on the slopes of the Hetao Irrigation Area cannot be planted with vegetation until it is improved. The introduced freshwater resources, carrying surface salts from the soil, pollute the water source used to improve the saline-alkali wasteland. This can easily lead to an increase in salt concentration in freshwater sources that meet chloride ion concentration standards when passing through the Hetao area for saline-alkali land improvement. Furthermore, landslides are highly likely to occur on the unvegetated slopes, further increasing the pollution of the freshwater source. Therefore, fundamentally improving the saline-alkali wasteland requires first improving the saline-alkali soil on the slopes of the Hetao area, thereby fundamentally improving the pollution-free nature of the introduced freshwater resources. Summary of the Invention:

[0004] Therefore, it is necessary to design a greening improvement device and method for high salinity slopes in the Hetao Irrigation Area, to improve the soil salinity of the slopes in Hetao, thereby reducing the risk of landslides and preventing the pollution of high-quality freshwater resources.

[0005] In a first aspect, this application provides a greening improvement device for high salinity slopes in the Hetao Irrigation Area. The greening improvement device for high salinity slopes in the Hetao Irrigation Area includes: a diversion channel set at the top of the slope, multiple first improvement components set laterally along the slope, and multiple second improvement components connected between any two adjacent first improvement components.

[0006] After multiple second improvement components and multiple first improvement components are interconnected, the slope protection is divided into multiple rectangular improvement zones, and the surface of each rectangular improvement zone is covered with desalination cloth.

[0007] Each first improved component includes multiple transverse pipes connected in a mortise and tenon joint; each transverse pipe includes: a lower first irrigation layer, a middle first steam layer, and a top drip irrigation layer;

[0008] Both the first irrigation layer and the first steam layer are buried in the saline-alkali soil of the slope protection.

[0009] Above each rectangular improvement zone, there are multiple drip irrigation pipes that communicate with the drip irrigation layer;

[0010] Each of the second improved components includes a connecting pipe, which has a second irrigation layer communicating with the first irrigation layer and a second steam layer communicating with the first steam layer; both the bottom of the first irrigation layer and the second irrigation layer are provided with seepage holes, and both sides of the first steam layer and the second steam layer are provided with steam diffusion holes;

[0011] The diversion channel has an upper water intake channel communicating with the drip irrigation layer and a lower water intake channel communicating with the first irrigation layer and the second irrigation layer.

[0012] The first steam layer and the second steam layer are connected to a heat source steam generator.

[0013] The first and second improvement components are used to leach water onto the saline-alkali soil via drip irrigation. At the same time, a salt-suppressing layer seeps out from the lower layer of the saline-alkali soil. After leaching, the water in the saline-alkali soil is evaporated by superheated gas evaporation. Meanwhile, desalination cloth is used to desalinate the soil, effectively improving the saline-alkali soil.

[0014] In one specific implementation scheme, the plurality of first improvement components are arranged at equal intervals along the slope surface of the slope protection. This allows for thorough leaching of the saline-alkali soil on the slope protection.

[0015] In one specific implementation scheme, the drip irrigation layer has a drainage channel; multiple arc-shaped limiting clips are arranged on both sides of the drainage channel, and both ends of the drip irrigation pipe are provided with positioning rings that cooperate with the corresponding arc-shaped limiting clips. This facilitates the detachable and fixed installation of the drip irrigation pipe.

[0016] In one specific implementation scheme, each of the transverse pipes has an overlapping portion at its first end and a fastening portion at its second end.

[0017] The interlocking parts between any two horizontally adjacent pipe fittings are fastened onto the overlapping part. This achieves a mortise and tenon connection, making installation faster.

[0018] In one specific implementation scheme, the diversion channel is connected to a water source irrigation component;

[0019] The water source irrigation component draws water from the upper water intake channel and then drips it through multiple drip irrigation pipes to the multiple rectangular improvement zones. By using fresh water, the saline-alkali soil in the rectangular improvement zones is desalinated and improved.

[0020] In one specific implementation scheme, each of the transverse pipes is provided with a connecting part on both sides that is inserted and mated with the corresponding connecting pipe.

[0021] The first irrigation layer is connected to the second irrigation layer through the connecting part;

[0022] The first steam layer is connected to the second steam layer via the connecting part. The connecting pipe allows for the diversion of water to the irrigation layer and the diversion of heat source gas to the steam layer.

[0023] In one specific implementation, the connecting part includes: a first protruding pipe and a second protruding pipe disposed on a first side of the transverse pipe; the first protruding pipe communicates with the first irrigation layer, and the second protruding pipe communicates with the first steam layer;

[0024] The first end of the connecting pipe fitting is provided with a first assembly hole and a second assembly hole; the first assembly hole communicates with the second irrigation layer, and the second assembly hole communicates with the second steam layer; wherein...

[0025] The first protruding tube is inserted into the first mounting hole, and the second protruding tube is inserted into the second mounting hole. The installation method is simple and has a high efficiency in diverting water and guiding gas.

[0026] In one specific implementation, the water source diverted by the irrigation component to the lower water intake channel seeps through the first irrigation layer and the second irrigation layer to form a salt-suppressing layer at the bottom of the plurality of rectangular improvement zones. The seeping water follows the slope of the slope protection to form the salt-suppressing layer.

[0027] In one specific implementation, the heat source steam generator evaporates the moisture in the saline-alkali soil by passing heat source gas through the first steam layer and the second steam layer, thereby desalinating the soil, and the salt is absorbed by the desalination cloth. Rapid desalination is achieved through the desalination cloth.

[0028] Secondly, a method for greening and improving high-salinity slopes in the Hetao irrigation area includes the following steps:

[0029] The factory prefabricates multiple horizontal pipes, multiple connecting pipes, diversion channels, and drainage channels made of PVC material in the designed dimensions.

[0030] The soil is cultivated to a depth of 20cm to 50cm along the slope. Multiple horizontal pipes, multiple connecting pipes, diversion channels, and drainage channels are laid in sequence in the saline-alkali soil of the slope to form multiple rectangular improvement zones.

[0031] Desalination cloth is laid sequentially on the surface of each rectangular improvement area, and multiple drip irrigation pipes are laid between any two adjacent transverse pipes along the slope of the slope protection until multiple rectangular improvement areas are completely covered.

[0032] The water source irrigation component is used to inject water with a chloride ion concentration into the diversion channel, and the water flow rate of the upper water intake channel is greater than that of the lower water intake channel.

[0033] The water from the drip irrigation layer is dripped and rinsed on the slope through multiple drip irrigation pipes. The water from the first and second irrigation layers forms a salt-suppressing layer in the deep-cultivated saline-alkali soil.

[0034] After the rinsing is completed, the water source irrigation components are turned off, and the heat source steam generator is started. The heat source steam generator evaporates the water in the alkaline soil through the first steam layer and the second steam layer, and the desalination cloth absorbs the salt and alkaline substances in the water.

[0035] The soil salinity was tested, and if the desalination target value was not reached, the water source irrigation components and heat source steam generator were repeatedly turned on.

[0036] Once the desalination target value is reached, multiple horizontal pipes, multiple connecting pipes, diversion channels, and drainage channels are removed. The deeply cultivated soil is compacted, and greenery is planted to improve the slope protection.

[0037] This method effectively improves the desalination rate of saline-alkali soil, reduces water pollution, and ensures the protective strength of slope protection. Attached image description:

[0055] Drainage channel - 900. Detailed implementation method:

[0056] See Figure 1 and Figure 2 As shown, Figure 1 This is a schematic diagram showing the distribution and installation of a greening improvement device for high salinity slopes in the Hetao Irrigation Area provided by the present invention. The greening improvement device for high salinity slopes in the Hetao Irrigation Area includes: a diversion channel set at the top of the slope 100; multiple first improvement components 700 arranged laterally along the slope 100; and multiple second improvement components 800 connecting any two adjacent first improvement components 700. In this application, the slope 100 is deeply tilled to a depth of 20-50 cm, and the first improvement components 700 and second improvement components 800 are pre-buried in the deeply tilled saline-alkali soil. In a specific embodiment, the deep tillage depth of the saline-alkali soil is 30 cm, then the height of the first improvement components 700 and second improvement components 800 is above 35 cm, and the pre-buried depth is 30 cm.

[0057] Multiple first-stage improvement components 700 are arranged at equal intervals along the slope surface of the slope protection 100. They thoroughly wash the saline-alkali soil of the slope protection 100. Furthermore, multiple second-stage improvement components 800 and multiple first-stage improvement components 700 are interconnected to divide the slope protection 100 into multiple rectangular improvement zones. Each rectangular improvement zone has a desalination cloth 200 laid on its surface. After deep tilling the saline-alkali soil of the slope protection 100, the soil is divided into multiple rectangular improvement zones, allowing for small-area sequential improvement in a segmented manner, thereby improving the desalination efficiency of the saline-alkali soil.

[0058] Combination Figure 3 As shown, each first improved component 700 includes multiple transverse pipes connected sequentially by tenon and mortise joints; each transverse pipe includes: a lower first irrigation layer 701, a middle first steam layer 702, and a top drip irrigation layer 703. The diversion ditch has an upper water intake channel 600 connected to the drip irrigation layer 703, and the upper water intake channel 600 is connected to the drip irrigation layer 703 through multiple drip irrigation pipes 710. Furthermore, in the specific installation of the first improved component 700, because the slope protection 100 of the Hetao irrigation area is relatively long, this application uses multiple split transverse pipes connected sequentially by tenon and mortise joints, thereby achieving the sequential connection of factory-prefabricated PVC transverse pipes to construct a complete first improved component 700. Specifically, the drip irrigation layer 703 has drainage channels; multiple arc-shaped limiting clips 707 are arranged on both sides of the drainage channels, and both ends of the drip irrigation pipe 710 are provided with positioning rings 712 that cooperate with the corresponding arc-shaped limiting clips 707. This facilitates the detachable and fixed installation of the drip irrigation pipe 710. Each horizontal pipe fitting has an overlapping portion 705 at its first end and a fastening portion 704 at its second end; the fastening portion 704 between any two adjacent horizontal pipe fittings fastens onto the overlapping portion 705. This achieves a tenon-and-mortise connection, making installation faster.

[0059] Therefore, it can be seen that a water source irrigation component 300 is connected to the diversion channel; this water source irrigation component 300 can be a deep well or a rainwater storage tank. The water source diverted from the water source irrigation component 300 to the upper water diversion channel 600 flows through multiple drip irrigation pipes 710 into the diversion ditch in the transverse pipe fittings, and the water source continues to flow into the interior of the drip irrigation pipes 710 in the diversion ditch. Combined with... Figure 4 As shown, both ends of the drip irrigation pipe 710 are equipped with positioning rings 712 that cooperate with the corresponding arc-shaped limiting clips 707. Furthermore, the drip irrigation pipe 710 is densely covered with drip irrigation holes 711, allowing water with the appropriate chloride ion concentration introduced from the upper water intake channel 600 to be drip-irrigated through multiple drip irrigation pipes 710 to wash the deeply tilled saline-alkali soil, achieving desalination and improvement of the saline-alkali soil in the rectangular improvement area by using fresh water.

[0060] Continue reading Figure 3 and Figure 5Both the first irrigation layer 701 and the first steam layer 702 are buried in the saline-alkali soil of the slope protection 100. By pre-burying them, the first irrigation layer 701 and the first steam layer 702 are located within the saline-alkali soil. After leaching the saline-alkali soil, the first irrigation layer 701 forms a salt-suppressing layer by flowing downstream along the slope of the slope protection 100, preventing salt from rising due to soil dryness. The first steam layer 702 is dehydrated again after leaching and desalination of the saline-alkali soil. After dehydration, the salt rises to the desalination cloth 200, which is made of geotextile and can be washed and replaced after repeated desalination over a long period.

[0061] Each of the second improvements includes a connecting pipe fitting, which has a second irrigation layer 820 communicating with the first irrigation layer 701 and a second steam layer 810 communicating with the first steam layer 702; such as Figure 7 As shown, the bottom of the first irrigation layer 701 and the second irrigation layer 820 are provided with seepage holes 823, the first steam layer 702 is provided with first steam diffusion holes 706 on both sides, and the second steam layer 810 is provided with second steam diffusion holes 811 on both sides.

[0062] When connecting the first irrigation layer 701 to the second irrigation layer 820 and the first steam layer 702 to the second steam layer 810 to achieve overall connectivity, each transverse pipe has a connecting part on both sides that plugs into the corresponding connecting pipe. The first irrigation layer 701 is connected to the second irrigation layer 820 through the connecting part; the first steam layer 702 is connected to the second steam layer 810 through the connecting part. The connecting pipes facilitate the diversion of water from the irrigation layers and the diversion of heat source gas from the steam layers.

[0063] Combination Figure 6 As shown, the connecting part includes: a first protruding pipe 708 and a second protruding pipe 709 disposed on the first side of the transverse pipe; the first protruding pipe 708 communicates with the first irrigation layer 701, and the second protruding pipe 709 communicates with the first steam layer 702; the first end of the connecting pipe is provided with a first mounting hole 822 and a second mounting hole 813; the first mounting hole 822 communicates with the second irrigation layer 820, and the second mounting hole 813 communicates with the second steam layer 810; the first protruding pipe 708 is inserted into the first mounting hole 822, and the second protruding pipe 709 is inserted into the second mounting hole 813. The installation method is simple and has a high effect on diverting water and guiding gas. It can be seen that the second end of the connecting pipe is correspondingly provided with a third protruding pipe 821 and a fourth protruding pipe 812, and the second side of the transverse pipe (not shown in the figure) is correspondingly provided with a third mounting hole and a fourth mounting hole, the third protruding pipe 821 is inserted into the third mounting hole, and the fourth protruding pipe 812 is inserted into the fourth mounting hole.

[0064] Water from the irrigation component 300 is diverted to the lower irrigation channel 500 and then seeps through the first irrigation layer 701 and the second irrigation layer 820 to form a salt-suppressing layer at the bottom of multiple rectangular improvement zones. The seeping water follows the slope of the slope protection 100 to form the salt-suppressing layer.

[0065] Therefore, the diversion channel has an upper water intake channel 600 connected to the drip irrigation layer 703, and a lower water intake channel 500 connected to the first irrigation layer 701 and the second irrigation layer 820. Water is pumped into the diversion channel through the water source irrigation component 300 box. The water in the upper water intake channel 600 flows through multiple drip irrigation pipes 710 and then washes the slope 100. A drainage channel 900 is installed at the bottom of the slope 100. Washing is carried out for 2 to 10 days until the soil salinity measured by sampling is ≤0.4%, at which point washing is stopped. The water in the lower water intake channel 500 simultaneously flows through the first irrigation layer 701 and the second irrigation layer 820, forming a salt-suppressing layer with high moisture content in the uncultivated hard soil layer to prevent salt increase due to dry weather later. After washing is completed, the first steam layer 702 and the second steam layer 810 are connected to a heat source steam generator 400. The heat source steam generator 400 evaporates the moisture in the saline-alkali soil by passing heat source gas through the first steam layer 702 and the second steam layer 810, thereby desalinating the soil. The salt is then absorbed by the desalination cloth 200. Rapid desalination is achieved through the desalination cloth 200.

[0066] In this invention, water is drip-irrigated to wash saline-alkali soil through the first improved component 700 and the second improved component 800. At the same time, a salt-suppressing layer seeps out from the lower layer of the saline-alkali soil. After the washing is completed, the water in the saline-alkali soil is evaporated by superheated gas evaporation. Meanwhile, desalination cloth 200 is used for desalination, which effectively improves the saline-alkali soil.

[0067] refer to Figure 8 This invention also provides a method for greening and improving high-salinity slopes in the Hetao Irrigation Area, comprising the following steps:

[0068] S1. Factory-prefabricated PVC multi-horizontal pipe fittings, multi-connecting pipe fittings, diversion channels, and drainage channels of the designed dimensions.

[0069] S2. Deeply cultivate the slope to a depth of 20cm to 50cm, and then lay multiple horizontal pipes, multiple connecting pipes, diversion channels, and drainage channels in sequence in the saline-alkali soil of the slope to form multiple rectangular improvement zones.

[0070] S3. Lay desalination cloth on the surface of each rectangular improvement area in sequence, and lay multiple drip irrigation pipes between any two adjacent transverse pipes along the slope of the slope protection until the multiple rectangular improvement areas are completely covered.

[0071] S4. Water source irrigation components are used to inject water with a chloride ion concentration into the diversion channel, and the water flow rate of the upper water intake channel is greater than that of the lower water intake channel.

[0072] S5. The water source of the drip irrigation layer is dripped and rinsed on the slope through multiple drip irrigation pipes. The water source of the first irrigation layer and the second irrigation layer forms a salt-suppressing layer in the deep-cultivated saline-alkali soil.

[0073] S6. After rinsing, turn off the water source irrigation components and start the heat source steam generator. The heat source steam generator evaporates the water in the alkaline soil through the first steam layer and the second steam layer, and the desalination cloth absorbs the salt and alkaline substances in the water.

[0074] S7. Detect soil salinity. If the desalination target value is not reached, repeat steps S2-S6 and continue to turn on the water source irrigation components and heat source steam generator.

[0075] S8. When the desalination target value is reached, remove multiple horizontal pipes, multiple connecting pipes, diversion channels, and drainage channels, compact the deeply cultivated soil, and plant greenery to improve the slope protection.

[0076] This method effectively improves the desalination rate of saline-alkali soils, reduces water pollution, and ensures the protective strength of slopes. Furthermore, during periods when no water source flows through the Hetao region, cash crops can be planted, increasing the utilization value of the Hetao irrigation area.
