Description

[0002] To meet the needs of direct irrigation in fields, fully utilize water resources, and improve farmland irrigation efficiency, canals are currently constructed in fields and lined with rigid concrete linings. However, this traditional canal construction method presents several problems: First, during canal construction, most of the earthwork is taken from the fields, resulting in the loss of significant fertile soil resources; second, the canal cross-section occupies a large area, and seepage water is lost through the canal embankments and channel beds, resulting in a reduction in effective arable land and a waste of irrigation water resources; third, the short construction components and long construction cycles make it difficult to ensure construction quality, seriously hindering the standardization and assembly process; fourth, in seasonally frozen areas, the canals face frost heave and thaw settlement, resulting in poor durability, water resource loss, and high subsequent maintenance costs. Furthermore, cracks are common in the rigid linings of field canals, causing significant irrigation water leakage, reducing irrigation water utilization, and potentially leading to a series of problems such as farmland infiltration and secondary salinization.

[0033] The present invention has the following beneficial effects:

[0034] 1. Based on the DFMA assembly design concept, this invention designs each field channel structure into standardized components with clear dimensions. These components can be prefabricated in the factory according to actual construction requirements and then transported to the farmland for direct installation. While ensuring the field channel's normal water conveyance function, this minimizes excavation and reduces construction steps, significantly shortening the construction period while ensuring construction quality.

[0035] 2. Each component of this invention is standardized with clearly defined design dimensions. The installation process is simpler and faster than traditional methods, with a shorter construction period. Given my country's vast territory and the widespread distribution of agricultural land resources, this technology offers broad potential for promotion and application, demonstrating its feasibility and foresight in wider-scale implementation. Furthermore, this technology offers significant room for future upgrades, such as increased convenience in automated water delivery, distribution control, and monitoring, providing broad prospects for further advancements in both technical capabilities and application effectiveness.

[0036] 3. Each component of this invention is designed to be environmentally friendly and lightweight without sacrificing its original functionality and strength requirements. For example, the water supply standard components are cut or 3D-printed from PE materials, while the telescopic support standard components and the curved lattice support standard components are primarily steel structures. Compared to traditional concrete structures, these are environmentally friendly, lightweight, and offer greater strength, making them easier to transport and install.

[0037] 4. The water supply standard parts of the present invention have standard parts of different sizes. The appropriate size can be selected for installation according to the specification parameter table according to the requirements of farmland irrigation, and the later maintenance is convenient; the telescopic support standard parts can also be flexibly increased or decreased in height according to the requirements of farmland irrigation to meet the water supply requirements of farmland under different irrigation conditions.

[0038] 5. The water delivery channel of the present invention adopts PE material, which avoids channel water leakage and improves the utilization rate of irrigation water compared with traditional concrete-lined channels. In addition, the cross-section of the water delivery standard parts in the invention is designed to be nearly circular with an opening on the top. Compared with the traditional U-shaped, trapezoidal and other fully open cross-section designs, the radiation heat exchange surface is reduced compared with the traditional cross-section, effectively suppressing evaporation during the water delivery process.

[0064] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0065] Example 1:

[0066] like Figure 1 As shown, the present invention provides a lattice-assembled near-field channel structure, comprising a plurality of concrete pier standard components 1 arranged sequentially along the channel line. The concrete pier standard components 1 are prefabricated reinforced concrete structures, and a water channel is provided above the concrete pier standard components 1. This abandons the previous practice of requiring large-scale earthwork when constructing channels, and instead only installs the pier standard components on cultivated land, thereby minimizing the area occupied by farmland and effectively ensuring the production efficiency of farmland. Because the channel is constructed using piers, passages are formed between the piers, breaking the traditional closed linear pattern of field channels. This helps improve the passage conditions for small animals in farmland, ensuring their life safety, and thus better protecting the ecological environment.

[0067] like Figure 2As shown, a telescopic support standard part 3 is installed on the upper part of the concrete pier standard part 1, and an arc-shaped lattice support standard part 4 is provided on the upper part of the telescopic support standard part 3. By adjusting the height of the telescopic support standard part 3, the height of the arc-shaped lattice support standard part 4 is adjusted, thereby realizing the height adjustment of the water transfer channel, thereby ensuring that the water transfer channel has a certain slope; the water transfer channel is formed by sequentially bonding a plurality of water transfer standard parts 2, and a nested standard part 6 is provided on the outer side of the bonding seam of the upper part of the two water transfer standard parts 2. By providing the nested standard part 6, the connection between the two water transfer standard parts 2 is made tighter; the bonding position of the two adjacent water transfer standard parts 2 is set inside the arc-shaped lattice support standard part 4, preferably in the middle. The support of the arc-shaped lattice support standard part 4 can avoid the connection being interrupted due to gravity during water transfer; water outlets 22 are provided on both sides of the water transfer standard part 2, and water is discharged outward through the water outlet 22 for farmland irrigation;

[0068] like Figure 2 and 3 As shown, in order to ensure the stability of the water supply standard component 2, first anchor bolt interfaces 21 are provided on both sides of the upper part of both ends of the water supply standard component 2, and second anchor bolt interfaces 41 are provided at the four corners of the arc-shaped lattice support standard component 4. The corresponding first anchor bolt interfaces 21 and second anchor bolt interfaces 41 are connected by an anchor bolt chain 5. The fixing effect of the anchor bolt chain 5 can cope with different water flow conditions and effectively avoid the shaking of the water supply standard component 2 caused by water flow.

[0069] The dimensions of each of the aforementioned standard components are set according to actual needs. The concrete pier standard component 1, telescopic support standard component 3, curved lattice support standard component 4, anchor chain 5, and the water supply standard component 2 that constitutes the water supply channel are all prefabricated in the factory and assembled on-site. The components are well-made and of stable quality, allowing for flexible channel layout tailored to farmland in diverse geographical conditions, ensuring project quality and improving construction efficiency. The standardized construction process facilitates subsequent maintenance and dismantling, reducing overall maintenance costs.

[0070] Example 2:

[0071] On the basis of Example 1, Figure 2 and 4As shown, the telescopic support standard component 3 is assembled from pressed steel and includes a column foot 31, wherein a fixed outer component 32 is provided on the upper portion of the column foot 31, and a telescopic inner component 34 is provided inside the fixed outer component 32. Corresponding reserved slots are provided on both sides of the fixed outer component 32 and the telescopic inner component 34. The relative positions of the fixed outer component 32 and the telescopic inner component 34 can be adjusted by inserting height adjustment bolts 33 into the reserved slots. The height can be flexibly adjusted according to the actual irrigation conditions of the farmland, thereby controlling the gradient to ensure the irrigation quota and irrigation efficiency. The arc-shaped lattice support standard component 4 is pressed from steel. The top of the telescopic inner component 34 is welded to the bottom of the arc-shaped lattice support standard component 4. The fixed height adjustment bolts 33 ensure that the telescopic inner component 34 does not move downward due to pressure during water delivery.

[0072] In a preferred embodiment, the height adjustment bolt 33 has a specification of M12 and a length of 145 mm. Other parameters such as Figure 4 shown.

[0073] Example 3:

[0074] Based on Examples 1 and 2, the upper portion of the water transfer standard component 2 is pre-reserved with openings, each sized to double the radius of the selected water transfer standard component 2 model. Water outlets 22 are preferably located at the quarter-point on either end of the water transfer standard component 2, and the length of the water transfer standard component 2 is preferably 6000 mm. The water transfer channel is symmetrically arranged with freely openable outlets 22 at intervals to facilitate irrigation. The water transfer channel's cross-section is designed to be nearly circular, which reduces the radiant heat exchange surface compared to traditional cross-sections, effectively suppressing evaporation of irrigation water during the transfer process.

[0075] like Figure 5 As shown, the inclination angle of the bonding seam between the two water supply standard parts 2 is 15°, which is cut in the factory using special equipment. During installation, the adjacent water supply standard parts 2 are first connected by using nested standard parts 6, and then bonded at the cutout of the water supply standard parts 2.

[0076] Example 4:

[0077] On the basis of Examples 1, 2 and 3, as Figure 6 and 7 As shown, a set of pre-embedded anchor bolts 11 are pre-embedded at each of the four upper corners of the concrete pier standard component 1, with each set consisting of four anchor bolts. The specification of the pre-embedded anchor bolts 11 is M12. There are four telescopic support standard components 3, which are respectively placed on the upper part of each set of pre-embedded anchor bolts 11. The telescopic support standard components 3 are fixed by the anchoring effect of the pre-embedded anchor bolts 11. Figure 8 As shown, a bottom plate is provided at the lower portion of the column foot 31 , and the bottom plate is 4 mm thick. The embedded anchor bolts 11 pass through the bottom plate and are fixed to the lower portion of the column foot 31 .

[0078] In a preferred embodiment, the concrete pier standard component 1 is 500mm long, 500mm wide, and 350mm high. The reserved groove is 150mm high. The interior of the concrete pier standard component 1 is reinforced with four Q235Φ16 vertical bars arranged longitudinally and two Q235Φ10 square stirrups arranged from bottom to top. The longitudinal bars are 50mm away from the outer side of the concrete on both sides. The concrete cover thickness outside the stirrups is 20mm, and the upper and lower stirrups are 100mm away from the top surface. The embedded anchor bolts 11 are 200mm long and embedded to a depth of 150mm. This rational reinforcement layout ensures structural stability. At the same time, the appropriate size ensures maximum cost reduction while ensuring application.

[0079] Example 5:

[0080] Based on the above embodiments, Figure 9 As shown, the anchor chain 5 consists of two bolts and one anchor chain. One end of the bolt is connected to the anchor chain, and the other end passes through the first anchor interface 21 or the second anchor interface 41 and is padded with a 2mm thick pad and fixed by a nut. Figure 10 As shown, the arc-shaped lattice support standard component 4 is a field-shaped hollow structure, the central angle corresponding to the arc is 120°, the radius is preferably 500mm, and the side length when viewed from above is preferably 884mm, which can be applied to different models of water supply standard components 2.

[0081] Example 6:

[0082] Based on the above embodiment, the selection of the water delivery standard part 2 follows the principles in Table 1. It can ensure that the irrigation target is achieved while saving materials and reducing costs. The material of the water delivery standard part 2 is preferably PE. Compared with traditional field channels, it can avoid unnecessary leakage problems, save water resources, and improve the utilization rate of irrigation water. At the same time, it has low roughness, fast and stable flow rate, and improves the irrigation efficiency of large areas of farmland. Figure 12 and 13 As shown, in a preferred embodiment, the radius of the water delivery standard part 2 is 250mm, the material thereof is PE material, the thickness is 15mm, and the length is 6000mm; Figure 14 As shown, in a preferred embodiment, the nested standard member 6 is in the shape of a hairpin, with a thickness of 10 mm on one side, and is arranged on the water delivery standard member 1 as shown in FIG. Figure 11 shown.

[0083] Table 1 Parameters of water delivery standard parts

[0084]

[0085] Based on different embodiments, the flow rate change and flow rate increment ratio of the PE channel of the present invention compared with the traditional concrete channel under different flow rates and different channel roughness conditions were measured, such as Figure 17As shown. After the irrigation water flows through a certain distance, the channel of the present invention significantly increases the flow rate of the irrigation water at the end, thereby improving the irrigation efficiency. Based on different embodiments, the stress and deformation changes of the PE channel of the present invention compared with the traditional concrete channel under different thicknesses, flow rates, and lateral wind conditions were measured. Figure 18 and Figure 19 As shown. When the thickness of the channel component of the present invention is greater than 15mm, the overall deformation of the channel is significantly reduced under the action of water flow and crosswind, and the deformed channel component can meet the water supply needs. Based on different embodiments, the change of water evaporation over time under different evaporation areas of the channel is measured, as shown in FIG. Figure 19 When the opening of the channel component is reduced according to the method of the present invention, the evaporation of irrigation water during transportation can be effectively reduced, and the irrigation water efficiency can be effectively improved.

[0086] Example 7:

[0087] Based on the above embodiments, Figure 15 and 16 As shown, the water outlet 22 includes a water outlet hole, and the water outlet is controlled by an opening and closing plate. A grip is provided on the upper part of the opening and closing plate, and the water outlet 22 is opened and closed by lifting or lowering the grip. Figure 15 and 16 Specific dimensions of a set of preferred embodiments are shown.

[0088] Example 8:

[0089] like Figure 1-16 As shown in the figure, a set of specific design parameters of a preferred embodiment are shown. The dimensions in the figure are all in mm and will not be elaborated in detail in the text.

[0090] The above embodiments 1-8 can be freely combined according to actual needs and are all within the scope disclosed by the present invention.

[0091] Example 9:

[0092] Based on the above-mentioned lattice assembled near-field channel structure, the present invention provides a construction method, comprising the following steps:

[0093] S1. Processing and producing standard parts in the factory, including concrete pier standard parts 1, telescopic support standard parts 3, curved lattice support standard parts 4 and different types of water supply standard parts 2;

[0094] S2. Mark the field channel layout route in the farmland according to the irrigation plan and mark the pre-embedded point of each concrete pier standard part 1;

[0095] S3. Excavate and level each marked pre-embedded point, and then select an appropriate burial depth according to the pre-designed burial depth requirements to pre-embed each concrete pier standard component 1;

[0096] S4. All concrete pier standard parts 1 are buried in the ground at the predetermined location. After the burial is completed, the surrounding land and debris are leveled;

[0097] S5. Then, four telescopic support standard parts 3 are installed on the first concrete pier standard part 1. Each telescopic support standard part 3 is installed on the anchor bolt reserved on the concrete pier standard part 1. Four telescopic support standard parts 3 are installed in sequence until the installation is completed on the last concrete pier standard part 1.

[0098] S6. Adjust the height of the telescopic support standard part 3 in sequence to meet the irrigation requirements;

[0099] S7, then sequentially install the arc-shaped lattice support standard parts 4 on the installed four telescopic support standard parts 3;

[0100] S8. Select a suitable model of water delivery standard component 2 according to the irrigation flow of the farmland at the construction site, and then horizontally place both ends of the selected model of water delivery standard component 2 on the arc-shaped lattice standard component 4;

[0101] S9, fixing the two ends of the anchor chain 5 of appropriate length to the first anchor interface 21 and the second anchor interface 41 in sequence;

[0102] S10, a nested standard component 6 is clamped on the outer portion of the upper portion of the bonding seam between two adjacent water delivery standard components 2, and then the two water delivery standard components 2 are bonded; thus, the construction of a lattice assembled near-field channel structure is completed.

[0103] The above-mentioned construction steps can be staggered and adjusted according to actual needs, with the main purpose of reducing construction difficulty and improving construction efficiency. Each structure of the field channel is designed as a standard part with clear dimensions, so that each standard part can be prefabricated in advance in the factory according to actual construction needs and finally transported to the farmland for direct installation. Through the construction method of the present invention, while ensuring the normal water conveyance function of the field channel, earth excavation is avoided to the greatest extent, the construction steps are reduced, and the construction quality is guaranteed while significantly shortening the construction period.
