The decision-making module executes the decision under the following requirement: a, b, and c satisfy the following formula:
[0029] d = a + b + c (1)
[0030] 2Y≥a≥1.5Y (2)
[0031] c≥X1+Y (3)

[0036] The collected wheel track widths and wheel widths are sorted from smallest to largest. The first 50% of wheel track widths are determined as the wheel track widths of small vehicles, and the last 50% are determined as the wheel track widths of large vehicles.
[0037] Preferably, when making the decision, Y is set to 30cm, and the other parameters are set to:
[0038] c = X1 + Y

[0042] (III) Beneficial Effects
[0043] This invention designs farm roads with a three-lane structure, allowing regular small vehicles to travel on the wide lane, while larger vehicles travel on the wide and narrow lanes. The wide and narrow lanes are designed based on the road width and the wheelbase of regular vehicles in the area. A calculation system is built based on data surveys, and the system uses a mathematical model for data analysis, resulting in a scientific and rational approach. While ensuring that rural vehicles can travel on concrete roads as much as possible, the width of the concrete pavement is minimized. Infill materials are used locally, greatly conserving resources. The road shoulders collect and store rainwater for planting forage grass, helping to reduce costs, protect the environment, and improve economic efficiency. Attached Figure Description

[0048] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0049] Please see Figure 1-3 The present invention provides a technical solution:
[0050] Please see Figure 1 A farm road based on wheel track design includes: a roadbed 1, a road surface 2 and a shoulder 3 built on the roadbed 1. The road surface 2 has a three-lane structure, wherein the left lane is a narrow concrete lane 21, the right lane is a wide concrete lane 23, and the middle lane is a fill lane 22. The roadbed 1 includes a plain soil compaction layer 11 and a 3:7 lime-soil layer 12 arranged from bottom to top. Biological culverts 13 are arranged at intervals in the upper part of the plain soil compaction layer 11. The two ends of the biological culverts 13 penetrate the shoulders 3 on both sides. The road surface 2 is laid on the upper part of the 3:7 lime-soil layer 12.
[0051] By setting up a three-tiered structure, the middle filler path 22 is not paved with concrete, reducing the hardening rate of the road surface 2 and saving resources. The biological culvert 13 provides shelter for animals and allows them to cross the road. Simultaneously, during agricultural irrigation, irrigation hoses can be laid through the biological culvert 13, preventing damage caused by crossing the road. The design of the narrow concrete path 21 and the wide concrete path 23 ensures that the wheels of conventional small vehicles generally travel on the wide path, while the wheels of large vehicles are distributed on both the wide and narrow paths. The design of the narrow concrete path 21 and the wide concrete path 23 is based on the width of the road surface 2 and the wheelbase of conventional vehicles in the area, aiming to minimize the width of the concrete road surface 2 while ensuring that rural vehicles can travel on it. The filler path 22 utilizes locally sourced materials as much as possible.
[0052] Furthermore, the shoulder 3 is filled with plain soil, the slope ratio of the shoulder 3 is 1:1, the road surface width d of the farm road is 3-6m, the base of the concrete narrow road 21 and the concrete wide road 23 is made of C25 commercial concrete, and a permeable concrete layer 211 is provided on the top, the permeable concrete layer 211 slopes from the connection with the filling road 22 towards the shoulder 3.
[0053] In order to reduce water accumulation on the road surface 2 and prevent scouring of the road shoulder 3, a permeable concrete layer 211 is installed to allow water to seep into the road shoulders 3 on both sides, thereby reducing the scouring force, protecting the road shoulders 3 and making use of them.
[0054] Preferably, the compacted soil layer 11, the 3:7 lime-soil layer 12, and the road surface 2 are arranged in a stepped manner, and the width of the compacted soil layer 11 is greater than the sum of the widths of the road surface 2 and the upper parts of the shoulders 3 on both sides.
[0055] The stepped layout, with the bottom layer always wider than the top layer, and the width of the compacted soil layer 11 being specified, is similar to a pyramid structure. This effectively ensures the stability of the road structure.
[0056] Preferably, please refer to Figure 2 A rainwater collection trough 31 is provided on the shoulder 3 close to the permeable concrete layer 211. A water outlet hole is provided on the inner wall of the rainwater collection trough 31 on the side away from the road surface 2. A water outlet pipe 32 is inserted into the water outlet hole. The water outlet pipe 32 is buried inside the shoulder 3 and extends to the outside of the shoulder 3. A drip irrigation pipe 33 is connected to the outer outlet of the water outlet pipe 32.
[0057] Rainwater seeping through permeable concrete is collected and utilized by setting up rainwater collection troughs 31. The outlet holes are typically located about one-third of the depth of the collection trough 31 from its bottom to allow for sedimentation and prevent silt from clogging the outlet pipe 32. It is best to install a filter screen, preferably made of cotton or geotextile, at the inlet of the outlet pipe 32. This serves two purposes: filtering and slowing the water flow into the outlet pipe 32, thus creating a slow release effect at the drip irrigation pipe 33 and improving water resource utilization. At intervals along the rainwater collection trough 31, a sand discharge pipe is recommended. This pipe connects to the bottom of the rainwater collection trough 31, runs through the road shoulder 3, and extends into the field. Regular flushing is necessary to prevent clogging and ensure normal operation. The rainwater collection trough 31 also serves to allow for manual water replenishment during the dry season. Water is then supplied to the plants on the road shoulder 3 through the outlet pipe 32 and drip irrigation pipe 33, saving the time and labor costs of laying separate irrigation pipes.
[0058] Preferably, the upper part and both sides of the road shoulder 3 are sown with green forage grasses, the types of which include grasses and leguminous forage grasses, mainly one or more of ryegrass, alfalfa, timothy grass, fescue, and foxtail grass.
[0059] Planting forage grass not only prevents soil erosion and greens the environment, but also makes comprehensive use of the land on the road shoulder. After the forage grass matures, it is harvested and used to feed cattle, sheep and other forage animals.
[0060] Preferably, the filling material of the filling channel 22 is one or a mixture of soil, sand, construction waste, and fly ash.
[0061] The filling materials are selected and matched according to the actual situation to achieve comprehensive utilization of waste, while also taking into account the reduction of transportation costs.
[0062] This invention provides a construction method for agricultural roads based on wheel track design, comprising:
[0063] S1. Pre-construction preparation: Before construction begins, the traverse lines, center lines, and benchmarks will be re-measured, and additional traverse lines and benchmarks will be added as needed based on the actual site conditions. After the measurement results are approved by the supervising engineer, the lines will be laid out according to the drawings, marking the center line of roadbed 1, the toe of the slope, and the location of side ditches. Weeds, tree roots, organic debris, and garbage within the construction area will be cleared manually or mechanically. The soil will be loosened to 10-15cm using a bulldozer, and then leveled using a grader.
[0064] S2, Construction of the plain soil compaction layer 11: First, use an excavator to cover the soil on the upper part of the foundation, and then use a road roller to compact it back and forth. After that, lay the biological culvert 13 on the plain soil compaction layer 11, continue to use an excavator to cover the soil, and use a road roller to compact it back and forth. Each compaction should be no less than 4 times, with a wheel overlap of no less than 50cm. The edges and corners should be compacted manually or with a frog-type rammer, and the compaction degree should be no less than 93%.
[0065] S3, Construction of the 37% lime-soil layer 12: Excavate and sieve the soil, the soil particle size is not greater than 15mm, the organic matter is less than 5%, the moisture content is 15%-18%, the lime is fully slaked and sieved, the particle size is not greater than 5mm, use a lime-soil mixer to mix, after the mixing is completed, spread on the top of the plain soil compaction layer 11, use a road roller to roll back and forth, roll at least 4 times, and the wheel overlap is not less than 50cm;
[0066] S4, Construction of Concrete Pavement 2: Includes the following steps:
[0067] ① Reinforcing Cage Fabrication: Fabricate and lay the reinforcing cage; prepare a reinforcing bar detailing based on the concrete slab type, and fabricate the reinforcing bars according to the detailing, ensuring accuracy in dimensions, quantity, and type. Label each type of semi-finished product to facilitate classification and construction by the binding personnel. The reinforcing bars are bound to form a reinforcing cage or mesh. The grade, diameter, quantity, and spacing of the reinforcing bars must meet the design requirements as specified in the drawings. The bound reinforcing bar skeleton must not be deformed or loosened, and deviations must not exceed the specifications.
[0068] ② Formwork construction: Install formwork for the left and right sections respectively, with steel formwork used for the sides and ends. Install side formwork to prevent formwork displacement, and ensure that the end formwork supports are firm and correctly positioned. After the formwork is assembled, check for lateral bending and verticality.
[0069] ③ Pouring and Vibration: Strictly control the slump during construction, do not add water arbitrarily, and prevent segregation. Concrete that has exceeded its initial setting time must not be used. Use both immersion and plate vibrators simultaneously for pouring and compaction to ensure the concrete is dense and reduce the generation of air bubbles on the sides.
[0070] The following points should be noted when pouring concrete:
[0071] The vibrator should be pulled out slowly to avoid creating voids.
[0072] When vibrating, the scale should be controlled to prevent under-vibration and over-vibration, so as to thoroughly compact the concrete, but the time should not be too long, so as to cause segregation.
[0073] In areas where immersion vibrators cannot reach, avoid contact with formwork, reinforcing bars, and embedded parts, and do not apply vibration directly through the reinforcing bars;
[0074] In corners of the formwork and areas that cannot be reached by a vibrator, a stake should be used for tamping to ensure a smooth and dense concrete surface.
[0075] The concrete must not be subjected to vibration for 24 hours after it has been compacted.
[0076] During the pouring process, close attention should be paid to the deformation of the formwork and grout leakage. Any occurrences should be corrected immediately.
[0077] Formwork removal: The formwork can only be removed after the concrete has reached a certain strength.
[0078] If a permeable concrete layer 211 is to be laid during construction, ordinary concrete is laid first, and the permeable concrete is made to slope towards the shoulder 3 by vibration. Then the permeable concrete is laid and vibrated a second time.
[0079] ④ Smoothing: After the water is absorbed, smooth it immediately with a coarse trowel. Finally, check the flatness of the road surface with a straightedge. If it meets the requirements, smooth it manually with a trowel.
[0080] ⑤ Grooving: After the surface is finished, perform horizontal texture treatment on the surface; when grooving, the dryness and humidity of the concrete surface should be well controlled. On-site inspection can be done by pressing with your hand. After the concrete is determined to be appropriate, place a channel steel on the formwork on both sides, with the flat side of the channel steel facing down and the concave side facing up, to provide a track for the grooving machine.
[0081] ⑥ Curing: After the grooving is completed, set up a fence to prevent people and vehicles from damaging the road surface. On rainy days, cover it with straw bags. Remove the formwork and carry out curing 12 hours after the concrete is poured.
[0082] ⑦ Cutting: Transverse contraction cut using a saw cut, 6cm deep and 5mm wide;
[0083] ⑧ Crack filling: Pour polyvinyl chloride sealant into the saw cut. Before filling, remove any temporary sealing material from the crack. The top of the crack should be flush with the road surface.
[0084] S9. Construction of infill pavement: Use transport machinery to evenly dump infill material onto infill pavement 22, use bulldozers to level it, and then use road rollers to compact it repeatedly and add infill material. Compact it no less than 4 times, with wheel overlap of no less than 50cm, so that the infill pavement is flush with the concrete pavement.
[0085] It should be noted that the shoulders 3 on both sides should be constructed simultaneously during the construction of the compacted soil layer 11 and the 3:7 lime-soil layer 12. The shoulders 3 on both sides should be filled after the road surface 2 is completed.
[0086] Please see Figure 3 This invention provides a system for designing the width of farm roads, comprising a data collection module and a decision-making module. The data collection module collects information including the wheelbase and width of conventional electric tricycles, conventional motorized tricycles, conventional agricultural four-wheelers, and wheelbase and width specifications for both tricycles and four-wheelers. The collected vehicle data is used for decision-making to meet the driving requirements of most vehicles. The decision-making module makes decisions based on the collected information and the input farm road width d, outputting widths a, b, and c. The decision-making module executes the decision under the following condition: a, b, and c satisfy the following formula:
[0087] d = a + b + c (1)
[0088] 2Y≥a≥1.5Y (2)
[0089] c≥X1+Y (3)
[0090] b≤X2-Y (4)
[0091] X2≥X1 (5)
[0092] In the formula: a is the width of the narrow concrete lane 21, b is the width of the infill lane 22, c is the width of the wide concrete lane 23, X1 is the average wheel track of small vehicles, X2 is the average wheel track of large vehicles, and Y is the average wheel width.
[0093] When implementing the decision, the width d of the farm road surface is determined manually based on road specifications and actual needs;
[0094] The collected wheel track widths and wheel widths are sorted from smallest to largest. The first 50% of wheel track widths are determined as the wheel track widths of small vehicles, and the last 50% are determined as the wheel track widths of large vehicles.
[0095] Small vehicles, which are also the type of vehicles most affected by road conditions in terms of driving experience, will primarily travel on the wide concrete road 23 after road surface 2 is constructed. Large vehicles will have their left and right wheels travel on the narrow and wide roads respectively. Only a very small number of large tricycles may have their middle wheels travel on the fill road 22, but this has little impact on the driving experience. Of course, this design cannot guarantee that all vehicles' wheels will travel on the concrete road surface, but it considers economic efficiency and caters to the travel needs of most vehicles, making it worthy of widespread adoption. The width values determined by the system can be manually adjusted according to actual needs.
[0096] The concrete narrow lane 21, especially for vehicles with narrow wheels, must at least ensure the required wheel width. The average wheel width is selected, and the concrete narrow lane 21 should be 1.5-2 times the average width. This is sufficient for narrow tires and generally adequate for wide tires. Even if the maximum wheel width is not reached, due to the size of the vehicles with large wheels, the slightly excessive portion can be used on the shoulder 3 or the fill lane 22 without affecting the driving experience. Furthermore, large vehicles generally do not operate on the road in rainy weather, so the phenomenon of large machinery creating muddy lanes does not need to be considered.
[0097] Preferably, when making the decision, Y is set to 30cm, and the other parameters are set to:
[0098] c = X1 + Y
[0099] b = X² - Y
[0100] X1 = X2.
[0101] Generally, 30cm is sufficient to meet the average wheel width requirement, and this value yields good design results. In the design process, the first 50% of the average wheel width is determined as the wheel width for small vehicles, and the second 50% as the wheel width for large vehicles. The middle 50%, which is exactly the value that reaches 50%, can be considered as a special case. Assuming that the traffic in the area is completely uniform, this value can be used as the wheel width for both large and small vehicles. When the middle 50% is used as the wheel width for both large and small vehicles, the probability of different vehicle models traveling on concrete roads is relatively high.
[0102] The present invention provides a computer device comprising a memory, a processor, and a computer program stored in the memory and executable on the processor, characterized in that the processor, when executing the computer program, performs the calculation of the system described above for designing the width of a farm road surface.
[0103] By using computers to perform data analysis and calculations, the width of road surface 2 can be calculated, which helps designers quickly determine the width of the three lanes of road surface 2.
[0104] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.

Pre-construction preparation: Lay out the lines, clear debris from the construction area, loosen the soil by bulldozing 10-15cm, and then level it with a grader; S2. Construction of the compacted soil layer: First, use an excavator to cover the soil on the upper part of the foundation, and then use a road roller to compact it back and forth. After that, lay the biological culvert on the compacted soil layer, continue to use an excavator to cover the soil, and use a road roller to compact it back and forth. Each compaction should be no less than 4 times, with a wheel overlap of no less than 50cm. The edges and corners should be compacted manually or with a frog-type rammer, and the compaction degree should be no less than 93%. S3, Construction of 37% lime-soil layer: Excavate and sieve the soil, the soil particle size is not greater than 15mm, the organic matter is less than 5%, the moisture content is 15%-18%, the lime is fully slaked and sieved, the particle size is not greater than 5mm, use a lime-soil mixer to mix, after the mixing is completed, spread on the top of the plain soil compaction layer, use a road roller to roll back and forth, roll for no less than 4 times, and the wheel overlap is not less than 50cm. S4. Concrete pavement construction: includes the following steps: ① Reinforcing cage fabrication: Fabricating and laying reinforcing cages; ② Formwork construction: Install formwork for the left and right sections respectively, with steel formwork used for the sides and ends; after the formwork is erected and assembled, check for lateral bending and verticality. ③ Pouring and Vibration: Pouring and vibration are carried out simultaneously using immersion vibrators and plate vibrators to ensure the compaction of the concrete and reduce the generation of air bubbles on the sides. ④ Smoothing: After the water is absorbed, immediately smooth the surface with a coarse trowel, and finally check the flatness of the road surface with a straightedge. ⑤ Grooving: After the surface is smoothed, a horizontal texture treatment is applied to the surface; ⑥ Curing: After the grooving is completed, set up a barrier to prevent people and vehicles from damaging the road surface; 12 hours after the concrete is poured, remove the formwork for curing. ⑦ Cutting: Transverse contraction cut using a saw cut, 6cm deep and 5mm wide; ⑧ Crack filling: Pour polyvinyl chloride sealant into the saw cut, with the top of the crack flush with the road surface; S5. Construction of infill pavement: Use transport machinery to evenly dump infill material into the infill pavement, use bulldozers to level it, and then use road rollers to compact it repeatedly and add infill material. Compact it no less than 4 times, with wheel overlap of no less than 50cm, so that the infill pavement is flush with the concrete pavement.
