[0018] The embodiments of the present application have the following advantages:

[0019] The present application provides a highway which, by using crushed stone as a base material, can ensure that the accumulated water in the roadbed is discharged in time during the later road operation, and can help dissipate heat in winter and alleviate the problem of frost heave.

[0020] In addition, the design of the first grid layer not only improves the overall strength of the highway, but also reduces the risk of uneven settlement caused by thawing frozen soil. Specifically, the top of the first connection node abuts against the gravel at the bottom of the gravel layer, which enhances the interlocking and integrity of the structure, thereby effectively restraining the occurrence of local deformation. That is, it not only ensures a good contact surface, but also enhances the interlocking performance of the entire structure, helps to disperse vehicle loads, reduces direct pressure on the base layer, and prevents overloaded vehicles on the road from damaging the base layer and affecting the safety of the road.

[0021] In simple terms, the first connection node of the first grid layer is mainly used to collect loads. After the top of the first connection node contacts the base layer, the first connection node can transfer the concentrated load on the top downward to the structure at the bottom (such as the roadbed layer mentioned below). The bottom of the first connection node can be a cross-shaped structure, which effectively transfers the load, making the load at the bottom one-fourth of the concentrated load, which can greatly reduce the damage and impact of stress concentration on the roadbed. Obviously, when the first connection node is subjected to load, the load will be dispersed and transferred to the cable at the first connection node in the first grid, and then the cable will form a pulling force on the first connection node, effectively increasing the load-bearing capacity, making the base layer more integrated, and restraining the occurrence of local deformation.

[0022] Furthermore, since the first grid mesh is located below the base layer, when the road surface layer collapses, grouting can be injected into the first grid mesh at the collapsed area to fill the collapsed area and strengthen the structure of the collapsed area, which is beneficial to later maintenance.

The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0038] In the relevant technology, there are often a large amount of permafrost and seasonal frozen soil in high-cold and high-altitude areas, such as Tibet. With the gradual expansion of the scale of engineering construction, the permafrost is increasingly disturbed, and the permafrost faces a huge risk of melting. After being disturbed, the permafrost will produce uneven settlement. The uneven settlement in the roadbed will affect the base layer in the road. The deformation of the base layer will directly cause the road surface to crack, forming horizontal cracks, longitudinal cracks and road slurry and other diseases, affecting the normal use of the highway. The reason is that in the later operation of the highway, it often experiences complex meteorological conditions, the road surface will crack and the side slope of the roadbed will have problems. Once rainwater enters the fill roadbed soil, it cannot be removed in time. After the saturation of the roadbed fill increases, the deformation of the road will increase; and when the water in the roadbed is not discharged in time, the roadbed will often produce frost heave disease during the sudden drop in temperature in winter, accompanied by new engineering problems, which directly affect the safe operation of the road.

[0039] like Figure 1 and Figure 2As shown, in order to solve the above-mentioned technical problems, an embodiment of the present application provides a highway, which includes a base layer 200, a first grid mesh layer and a road base layer 500. The base layer 200, the first grid mesh layer and the road base layer 500 are arranged in sequence from top to bottom. The first grid mesh 400 layer includes a first grid mesh 400. The first grid mesh 400 has a first connection node, the top of the first connection node is extended upward, and the bottom of the first connection node is extended downward; wherein the base layer 200 is a gravel layer, the top of the first connection node and the gravel at the bottom of the gravel layer are abutted, and the bottom of the first connection node and the top of the road base layer 500 are abutted.

[0040] In these embodiments, the present application provides a technical solution for highway structures in high-cold and high-altitude areas, especially in areas with a large amount of permafrost and seasonally frozen soil. The purpose is to solve the problem of uneven settlement caused by the permafrost layer being disturbed by engineering construction, and to prevent the resulting road diseases, such as transverse cracks, longitudinal cracks and road mudslides.

[0041] The highway structure includes a base layer 200, a first grid layer and a roadbed layer 500 arranged in sequence from top to bottom. The base layer 200 is composed of crushed stone, has good drainage performance, helps to reduce water accumulation in the roadbed, and reduces damage to the roadbed caused by freezing and expansion of water.

[0042] The first grid mesh layer includes a first grid mesh 400 having first connection nodes extending upwards. The first connection nodes are in contact with the bottom of the gravel layer, thereby enhancing the stability of the overall structure, helping to disperse the load and reducing the risk of uneven settlement.

[0043] The road base layer 500 is located at the bottom layer and supports the basic support function of the entire highway structure.

[0044] It should be noted that by using crushed stone as the base material 200, it can ensure that the accumulated water in the roadbed is discharged in time during the later road operation, and help dissipate heat in winter to alleviate the frost heave problem.

[0045] Moreover, the design of the first grid mesh layer not only improves the overall strength of the highway, but also reduces the risk of uneven settlement caused by thawing frozen soil. Specifically, the top of the first connection node abuts against the gravel at the bottom of the gravel layer, which enhances the interlocking and integrity of the structure, thereby effectively restraining the occurrence of local deformation. That is, it not only ensures a good contact surface, but also enhances the interlocking performance of the entire structure, helps to disperse vehicle loads, reduces direct pressure on the base layer 200, and prevents overloaded vehicles on the road from damaging the base layer 200 and affecting the safety of the road.

[0046] In simple terms, the first connection node of the first grid mesh layer is mainly used to collect loads. After the top of the first connection node contacts the base layer 200, the first connection node can transfer the concentrated load on the top downward to the structure at the bottom (such as the roadbed layer 500 described below). The bottom of the first connection node can be a cross-shaped structure, which effectively transfers the load, making the load at the bottom one-fourth of the concentrated load, which can greatly reduce the damage and impact of stress concentration on the roadbed. Obviously, when the first connection node is subjected to load, the load will be dispersed and transferred from the first grid mesh 400 to the cable at the first connection node, and then the cable will form a pulling force on the first connection node, effectively increasing the load-bearing capacity, making the base layer 200 more integrated, and restraining the occurrence of local deformation.

[0047] Furthermore, since the first grid mesh 400 is located below the base layer 200, when the road surface layer 100 collapses, grouting can be injected into the first grid mesh 400 at the collapsed area to fill the collapsed area and strengthen the structure of the collapsed area, which is beneficial to subsequent maintenance.

[0048] like Figure 1 and Figure 2 As shown, in some embodiments, the crushed stone particle size of the crushed stone layer is the same as the diameter of the top of the first connection node.

[0049] In these embodiments, when the crushed stone particle size of the crushed stone layer is the same as the diameter of the top of the first connection node, the interlocking performance of the structure can be significantly enhanced. This design enables the first grid mesh 400 to be better embedded in the crushed stone layer to form a more compact overall structure.

[0050] The same size design helps achieve a more even load distribution. The pressure generated by vehicles passing over the road surface can be more effectively transferred to the entire base 200 structure, reducing local stress concentrations and thus reducing the risk of uneven settlement.

[0051] By accurately matching the crushed stone particle size and the diameter of the top of the connection node, the first grid mesh 400 can be effectively prevented from displacement or deformation during use, which not only enhances the overall stability of the road, but also extends its service life.

[0052] Simply put, the setting of the first connection node provided is close to the particle size of the gravel used in the roadbed. Its main function is to ensure a good bite force between the first connection node and the gravel, and to prevent the shear surface from being generated on the contact interface between the gravel and the first grid mesh 400 during the shearing process. The setting of the first connection node greatly improves the bearing capacity of the entire roadbed structure.

[0053] The selection of crushed stone requires special attention to the consistency of its particle size to ensure that it matches the diameter of the top of the first connection node. In addition, the manufacturing of the first grid net 400 and its first connection node also requires high precision to ensure seamless connection in actual construction.

[0054] During the construction process, the gravel layer must be laid strictly according to the design requirements, and it is ensured that the top of the connection node of the first grid mesh 400 is in full contact and abutment with the gravel at the bottom of the gravel layer. Specific tools and techniques are required to ensure the quality of construction.

[0055] Obviously, by precisely matching the crushed stone particle size and the diameter of the top of the connection node, the stability and deformation resistance of the entire road structure are enhanced. Uniform load distribution can reduce local stress concentration and reduce the risk of base 200 damage caused by vehicle overload or other factors. Reducing the occurrence of uneven settlement and local deformation helps to extend the service life of the highway and reduce maintenance costs.

[0056] For example, the mesh size of the first grid net 400 is smaller than the particle size of the gravel, and such a setting can further improve the stability of the road. Optionally, the mesh size of the first grid net 400 is filled with gravel of smaller size to further improve the stability.

[0057] like Figure 2 and Figure 3 As shown, in some embodiments, the first grid mesh 400 includes multiple first cables and multiple first support members, and the multiple first support members are distributed in the first grid mesh 400 layer at intervals, and any two adjacent first support members are connected by the first cable, so that the first support members form a first connection node.

[0058] In these embodiments, the first grid mesh 400 includes a plurality of first cables and a plurality of first supports, which work together to form a strong and stable structure.

[0059] The first cable is the main connecting element and is usually made of high-strength material (such as steel wire rope) with good tensile strength and durability.

[0060] The first support members are distributed at intervals in the first grid mesh 400 layer to play a supporting and fixing role. The support members can be various shapes, such as round, square or other geometric shapes, depending on the design requirements and application scenarios.

[0061] Any two adjacent first support members are connected by first cables to form a grid-like structure. This not only enhances the overall stability, but also enables the first support members to form first connection nodes, further improving the strength and anti-deformation ability of the structure. In other words, the top of the first support member abuts against the gravel, and the bottom of the first support member abuts against the top of the roadbed 500.

[0062] Obviously, by connecting the first supporting members through the first cables, the entire first grid net 400 forms a compact integral structure. This design helps to disperse the vehicle load and reduce local stress concentration, thereby reducing the risk of uneven settlement.

[0063] Furthermore, the presence of the first connection node enhances the interlocking performance of the structure, so that the first grid mesh 400 can be better embedded in the gravel layer to form a more solid overall structure, which helps prevent the first grid mesh 400 from being displaced or deformed during use.

[0064] Furthermore, this grid structure not only provides good drainage performance, but also helps dissipate heat in winter and alleviates the problem of frost heave. The moisture in the gravel layer can be discharged through the gaps in the grid, reducing the damage to the roadbed caused by freezing and expansion.

[0065] Exemplarily, the first cable is made of high-strength steel wire rope or other similar materials to ensure that it has sufficient tensile strength and corrosion resistance.

[0066] The first support member can be made of stainless steel or other corrosion-resistant materials to ensure stability and durability for long-term use.

[0067] During the construction process, it is necessary to lay the first grid mesh 400 in strict accordance with the design requirements and ensure that the connection between the first cable and the first support is firm and reliable. The specific installation steps include:

[0068] Exemplarily, the design of the first grid mesh 400 is as follows:

[0069] The first cable is a high-strength steel wire rope with a diameter of 8 mm and a tensile strength of more than 1500 MPa. The first support member is a stainless steel cylinder with a diameter of 50 mm, which is distributed in the first grid mesh 400 layers at intervals. Any two adjacent first support members are connected by the first cable to form a first connection node. The entire structure forms a tight grid shape, ensuring the stability and drainage performance of the road base 500.

[0070] Exemplarily, the first support member is connected to the steel wire rope via a lock, and the main function of the lock is to lock the steel wire rope to prevent it from sliding, thereby ensuring the stability of the grid in the first grid mesh 400 and preventing the grid from deforming due to excessive stress.

[0071] like Figure 2 As shown, in some embodiments, a plurality of first support members are distributed in the first grid mesh 400 layer in a rectangular array at intervals.

[0072] In these embodiments, the plurality of first support members are spaced apart and distributed in a rectangular array. This means that the distance between each support member is fixed and forms a regular rectangular grid, that is, the grid of the first grid mesh 400 is a square grid. Of course, in other embodiments, the grid may also be set to a triangular grid, a pentagonal grid, etc.

[0073] like Figure 1 As shown, in some embodiments, drainage ditches 300 are respectively provided on both sides of the base layer 200, and the bottom of the drainage ditch 300 is connected to the first grid mesh 400 layer.

[0074] In these embodiments, drainage ditches 300 are respectively arranged on both sides of the base layer 200, and the bottoms of these drainage ditches 300 are connected to the first grid mesh 400. This design can significantly improve the drainage performance of the road structure, reduce the impact of water accumulation on the roadbed and road surface, and is particularly suitable for environments with a large amount of permafrost and seasonal frozen soil in high-cold and high-altitude areas.

[0075] Drainage ditches 300 are respectively arranged on both sides of the base layer 200 . The main function of these drainage ditches 300 is to collect and drain rainwater or other water sources flowing down from the road surface to prevent moisture from penetrating into the road base layer 500 .

[0076] The bottom of the drainage ditch 300 is connected to the first grid mesh 400 layer, so that the water filtered through the gravel layer can flow smoothly into the drainage ditch 300 and be discharged in time, which not only enhances the drainage effect but also reduces the damage to the roadbed caused by the freezing and expansion of water.

[0077] The drainage ditch 300 not only improves the drainage performance, but also enhances the stability of the entire road structure. By draining water in time, it can effectively prevent water from penetrating into the roadbed and reduce the problem of uneven settlement caused by water.

[0078] The presence of the drainage ditch 300 also helps to dissipate heat in winter and further alleviate frost heave disease. By draining excess water, the pressure on the roadbed caused by water freezing and expansion is reduced, and it is also beneficial to dissipate heat and maintain the stability of the roadbed.

[0079] Exemplarily, the drainage ditch 300 is made of concrete or prefabricated components to ensure that it has sufficient strength and durability.

[0080] like Figure 1As shown, in some embodiments, the highway also includes a road base layer 500, which is located at the bottom of the first grid mesh 400 layer, and the bottom of the first connection node is abutted against the top of the road base layer 500; wherein the road base layer 500 includes an upper road base layer 510, a buffer layer 520 and a lower road base layer 550, and the upper road base layer 510, the buffer layer 520 and the lower road base layer 550 are arranged in sequence from top to bottom, and the buffer layer 520 is a block stone layer.

[0081] In these embodiments, the structure of the highway includes not only the base layer 200 and the first grid mesh 400 layer, but also a road base layer 500 located at the bottom of the first grid mesh 400 layer. The road base layer 500 is further subdivided into an upper road base layer 510, a buffer layer 520, and a lower road base layer 550. This multi-layer design is intended to improve the overall stability and durability of the road, and is particularly suitable for environments where there is a large amount of permafrost and seasonal frozen soil in high-cold and high-altitude areas.

[0082] The roadbed layer 500 is located at the bottom of the first grid mesh 400 layer and is the basic support layer of the entire road structure. The bottom of the first connection node abuts against the top of the roadbed layer 500, ensuring close contact and force transmission between the upper and lower layers.

[0083] The uppermost layer of the roadbed 500 is directly in contact with the first grid mesh 400 layer, playing a role of transition and support. The buffer layer 520 is a block stone layer, located between the upper roadbed 510 and the lower roadbed 550, and is a drainage structure set in the fill area of ​​the roadbed 500. It is mainly composed of large blocks of stone. Paving a block stone layer of a certain thickness can effectively prevent the roadbed 500 from producing uneven settlement, greatly improving the bearing capacity of the roadbed. At the same time, larger blocks of stone are not easy to form capillary water, and are not easy to produce frost heave during the rapid drop in temperature in winter, which prevents the capillary water from rising underground. It has good drainage performance and buffering effect, and can effectively absorb and disperse the pressure from the upper part. By setting the buffer layer 520, the vehicle load can be effectively absorbed and dispersed, and the local stress concentration can be reduced, thereby reducing the risk of uneven settlement. At the same time, the bottom of the first connection node abuts against the top of the roadbed 500, which enhances the connection strength between the upper and lower layers and improves the anti-deformation ability.

[0084] The lower road base layer 550 is located at the bottom of the road base layer 500 and provides basic support for the entire highway structure. The multi-layered road base layer 500 significantly enhances the overall stability of the highway. The upper road base layer 510, the buffer layer 520 and the lower road base layer 550 each have different functions and work together to ensure the stability of the road structure.

[0085] For example, the upper road base layer 510 is made of a material with good bearing capacity and stability, such as graded crushed stone or lime-stabilized soil.

[0086] The buffer layer 520 (rock layer) is made of rock material with a moderate particle size and good drainage performance and buffer effect.

[0087] The lower road base 550 uses soil materials with high compaction degree, such as natural gravel or improved soil, to ensure the stability and bearing capacity of the foundation.

[0088] During the construction process, it is necessary to lay each layer in strict accordance with the design requirements and ensure close contact and force transmission between the layers. The specific installation steps include: laying the lower roadbed 550 and compacting it to ensure that it has sufficient bearing capacity. Laying the buffer layer 520 (block layer) on the lower roadbed 550 to ensure its drainage performance and buffering effect. Laying the upper roadbed 510 and connecting it to the first grid mesh 400 layer to ensure that the bottom of the first connection node is in close contact with the top of the roadbed 500.

[0089] For example, the upper road base 510 is made of graded crushed stone material with a thickness of 30 cm to ensure good bearing capacity and stability. The buffer layer 520 is made of block stone material with a particle size of 10-30 cm and a thickness of 50 cm, which has good drainage performance and buffering effect. The lower road base 550 is made of natural gravel material with a thickness of 60 cm, which is fully compacted to ensure the stability and bearing capacity of the foundation.

[0090] It should be noted that during the operation of the highway, in the collapsed area of ​​the highway, the road can be quickly repaired by injecting grout into the buffer layer 520 .

[0091] like Figure 1 and Figure 4 As shown, in some embodiments, the road base layer 500 also includes a second grid mesh 530 layer, the second grid mesh 530 layer is located between the buffer layer 520 and the lower road base layer 550, the second grid mesh 530 layer includes a second grid mesh 530, the second grid mesh 530 has a second connection node, the top of the second connection node is extended upward, the bottom of the second connection node is extended downward, the top of the second connection node is abutted against the block stone at the bottom of the block stone layer, and the bottom of the second connection node is abutted against the top of the lower road base layer 550.

[0092] In these embodiments, the road base layer 500 also includes a second grid mesh 530 layer, which is located between the buffer layer 520 (block layer) and the lower road base layer 550, further enhancing the stability and deformation resistance of the road structure, and is particularly suitable for environments in high-cold and high-altitude areas where there is a large amount of permafrost and seasonal frozen soil.

[0093] The second grid mesh 530 layer is located between the buffer layer 520 (rock layer) and the lower roadbed 550, and plays a role in enhancing structural stability and dispersing loads.

[0094] The second grid mesh 530 includes a plurality of second connection nodes and second cables, the second connection nodes having a configuration in which the top portion extends upward and the bottom portion extends downward.

[0095] The top of the second connection node abuts against the block stone at the bottom of the block stone layer, ensuring close contact and force transmission between the upper and lower layers. The bottom of the second connection node abuts against the top of the lower roadbed 550, further enhancing the stability of the entire roadbed structure.

[0096] Obviously, the design of the second grid mesh 530 layer significantly enhances the overall stability of the road. By abutting the top of the second connection node with the block stone at the bottom of the block stone layer, and abutting the bottom with the top of the lower roadbed 550, a solid overall structure is formed.

[0097] In addition, the stone layer as a buffer layer 520 has good drainage performance, and the design of the second grid mesh 530 layer further enhances this effect. The top of the second connection node is in contact with the stone at the bottom of the stone layer, which can better guide the water to drain and reduce the impact of water on the lower roadbed. At the same time, it helps to dissipate heat in winter and further alleviate frost heave disease.

[0098] The top and bottom extension design of the second connection node can effectively absorb and disperse the pressure from the top, reduce local stress concentration, and thus reduce the risk of uneven settlement. At the same time, it also improves the deformation resistance of the entire structure.

[0099] Exemplarily, the second grid mesh 530 layer uses high-strength steel wire ropes and stainless steel nodes to ensure that it has good tensile strength and corrosion resistance.

[0100] In some embodiments, the diameter of the top of the second connection node is equal to the particle size of the rocks in the rock layer.

[0101] In these embodiments, the top diameter of the second connection node is equal to the particle size of the block of the block layer. This design helps to enhance the integrity and stability of the structure and optimize the drainage performance.

[0102] The second connection node is a key component of the second grid mesh 530 layer, and its top extends upward and abuts against the block stones at the bottom of the block stone layer. The diameter of the top of the second connection node is equal to the particle size of the block stones in the block stone layer. This precise matching design can ensure better contact surface and interlocking effect, thereby improving the stability and integrity of the entire structure.

[0103] That is, when the diameter of the top of the second connection node is equal to the particle size of the block stone layer, the interlocking performance of the structure can be significantly enhanced. This design enables the second grid mesh 530 to be better embedded in the block stone layer to form a more compact overall structure. The design of the same size helps to achieve a more uniform load distribution. The pressure generated when the vehicle passes through the road surface can be more effectively transmitted to the entire base 200 structure, reducing local stress concentration, thereby reducing the risk of uneven settlement.

[0104] Furthermore, by accurately matching the diameter of the top of the second connection node with the particle size of the block stones in the block stone layer, the second grid mesh 530 can be effectively prevented from displacement or deformation during use, which not only enhances the overall stability of the road, but also extends its service life.

[0105] Moreover, this design further optimizes drainage performance. Due to the good contact and interlocking between the second connection node and the block stone layer, moisture can be quickly drained through the grid gaps, reducing the damage to the roadbed caused by water freezing and expansion.

[0106] For example, the mesh size of the second grid net 530 is smaller than the particle size of the block stone, and such a setting can further improve the stability of the highway. Optionally, the mesh size of the second grid net 530 is filled with smaller crushed stones or blocks of stone to further improve the stability.

[0107] like Figure 4 As shown, in some embodiments, the second grid mesh 530 includes multiple second cables and multiple second support members, and the multiple second support members are distributed in the second grid mesh 530 layer at intervals, and any two adjacent second support members are connected by a second cable, so that the second support members form a second connection node.

[0108] In these embodiments, the plurality of second cables and the plurality of second supports form a strong and stable structure through a specific arrangement and connection method, aiming to enhance the overall stability and drainage performance of the road.

[0109] The second cable is the main connecting element and is usually made of high-strength material (such as steel wire rope) with good tensile strength and durability.

[0110] The second support members are distributed at intervals in the second grid mesh 530 layer to play a supporting and fixing role. The support members can be various shapes, such as round, square or other geometric shapes, depending on the design requirements and application scenarios.

[0111] Any two adjacent second support members are connected by a second cable to form a second connection node, which not only enhances the overall stability but also enables the second support members to form a second connection node, further improving the strength and deformation resistance of the structure.

[0112] By connecting the second supporting members through the second cables, the entire second grid net 530 forms a compact integral structure. This design helps to disperse the vehicle load and reduce local stress concentration, thereby reducing the risk of uneven settlement.

[0113] Furthermore, the presence of the second connection node enhances the interlocking performance of the structure, so that the second grid mesh 530 can be better embedded in the block stone layer to form a more solid overall structure, which helps prevent the second grid mesh 530 from displacement or deformation during use.

[0114] Furthermore, this grid structure not only provides good drainage performance, but also helps dissipate heat in winter and alleviates the problem of frost heave. The moisture in the block layer can be discharged through the gaps in the grid, reducing the damage to the roadbed caused by freezing and expansion.

[0115] For example, the second cable is made of high-strength steel wire rope or other similar materials to ensure that it has sufficient tensile strength and corrosion resistance. Optionally, a high-strength steel wire rope with a diameter of 8 mm is used, and the tensile strength reaches more than 1500 MPa.

[0116] The second support member can be made of stainless steel or other corrosion-resistant materials to ensure stability and durability for long-term use. Optionally, the second support member is a stainless steel cylinder with a diameter of 50 mm, distributed in a rectangular array.

[0117] During the construction process, it is necessary to lay the second grid mesh 530 in strict accordance with the design requirements and ensure that the connection between the second cable and the second support member is firm and reliable.

[0118] Optionally, the second support member is connected to the second cable via a lock, and the main function of the lock is to lock the second cable to prevent the second cable from sliding, thereby ensuring the stability of the grid in the second grid mesh 530 and preventing the grid from deforming due to excessive stress.

[0119] like Figure 1 As shown, in some embodiments, the highway also includes a composite pipeline 600, which includes a straight pipe 620 and a curved pipe 610. The straight pipe 620 is located below the second grid mesh 530 layer, and the straight pipe 620 is extended along the width direction of the highway. The two ends of the curved pipe 610 are respectively connected to the corresponding ends on the straight pipe 620, and the middle part of the curved pipe 610 is located in the upper road base layer 510; wherein, a plurality of straight pipe 620 inlets are distributed on at least one upward side of the straight pipe 620, and a plurality of curved pipe 610 inlets are distributed on at least one upward side of the curved pipe 610.

[0120] In these embodiments, the drainage performance of the road is enhanced and it is ensured that moisture can be drained quickly and effectively, thereby reducing the impact of water accumulation on the roadbed and road surface.

[0121] The composite pipeline 600 is composed of a straight pipe 620 and a curved pipe 610, and is mainly used for drainage and guiding water flow. The straight pipe 620 is located below the second grid mesh 530 layer, extending along the width direction of the highway, and is used to collect water from the base layer 200 and the buffer layer 520, and the two ends of the straight pipe 620 extend out of the road base layer 500, so that it can be directly discharged. The two ends of the curved pipe 610 are respectively connected to the corresponding ends on the straight pipe 620, and the middle part is located in the upper road base layer 510, which is used to guide the water from the straight pipe 620 to the designated drainage position.

[0122] For example, at least one side of the straight tube 620 facing upward is provided with a plurality of straight tube 620 inlets for collecting water infiltrating from above. Of course, in other embodiments, the straight tube 620 inlets may be distributed on the entire surface of the straight tube 620. For example, the diameter of each straight tube 620 inlet is 10 cm and the interval is 5 meters.

[0123] For example, at least one side of the curved pipe 610 facing upward is also provided with a plurality of curved pipe 610 inlets for collecting water flowing in from different directions. Of course, in other embodiments, the entire surface of the curved pipe 610 may also be provided with curved pipe 610 inlets. For example, the diameter of each curved pipe 610 inlet is 10 cm and the interval is 5 meters.

[0124] Obviously, the design of the composite pipe system 600 significantly enhances the drainage performance of the road. Through the combination of the straight pipe 620 and the curved pipe 610, water can enter from multiple directions and be quickly discharged, reducing the impact of water accumulation on the roadbed and road surface. The inlet design of the straight pipe 620 and the curved pipe 610 ensures that water can quickly enter the pipeline system, preventing water from being retained in the base layer 200 and the buffer layer 520 for a long time, and reducing the damage to the roadbed caused by water freezing and expansion.

[0125] Furthermore, the straight pipe 620 is extended along the width direction of the road, and the curved pipe 610 guides the water from the straight pipe 620 to the designated drainage position, thereby optimizing the water flow path and ensuring that the water can be discharged smoothly.

[0126] The straight pipe 620 and the curved pipe 610 are made of corrosion-resistant materials, such as HDPE (high-density polyethylene) or PVC (polyvinyl chloride), metal stainless steel pipes, etc., to ensure that they have good durability and corrosion resistance.

[0127] Optionally, the inlet of the straight pipe 620 and the inlet of the curved pipe 610 should have a certain filtering function to prevent larger impurities from entering the pipeline system and affecting the drainage effect.

[0128] During the construction process, it is necessary to lay the composite pipeline 600 in strict accordance with the design requirements and ensure the close connection between the various parts. The specific installation steps include: laying the lower roadbed 550 and compacting it to ensure that it has sufficient bearing capacity. Lay the second grid mesh 530 layer on the lower roadbed 550 to ensure that the bottom of the second connection node is in close contact with the top of the lower roadbed 550. Install the straight pipe 620 to ensure that it extends along the width of the highway and the inlet of the straight pipe 620 faces upward to collect the infiltrated moisture. Install the curved pipe 610 to ensure that its two ends are connected to the straight pipe 620, and place the middle part in the upper roadbed 510, while ensuring that the inlet of the curved pipe 610 faces upward to facilitate the collection of moisture. Lay the block stone layer (buffer layer 520) on the second grid mesh 530 layer to ensure that the top of the second connection node is in full contact and contact with the block stone at the bottom of the block stone layer.

[0129] like Figure 5 As shown, in some embodiments, a spiral blade is disposed on the outer side of the curved pipe 610 .

[0130] In these embodiments, the drainage performance and structural stability of the composite pipe 600 system are further enhanced, and it is particularly suitable for application scenarios that require efficient drainage and prevention of blockage.

[0131] The outer side of the curved pipe 610 is provided with spiral blades, which are distributed in a spiral along the outer wall of the curved pipe 610, thereby enhancing the overall strength of the pipe, and helping to guide the direction of water flow and improve drainage efficiency.

[0132] Furthermore, the spiral blades increase the rigidity and compression resistance of the elbow 610, making it more durable under complex geological conditions. Among them, the spiral blades help guide the water flow, reduce turbulence and resistance, and ensure that the water can flow smoothly and avoid blockage.

[0133] like Figure 1 As shown, in some embodiments, the highway also includes a highway monitoring system 700, which includes a remote control terminal, a plurality of deformation sensors and a data acquisition module 730. The plurality of deformation sensors are buried and distributed in the road base layer 500. The deformation sensors are used to detect the deformation amount of the road base layer 500. The data acquisition module 730 is electrically connected to the plurality of deformation sensors respectively, and the data acquisition module 730 is also electrically connected to the remote control terminal. The data acquisition module 730 is used to collect the detection data of the deformation sensor and transmit it to the remote control terminal.

[0134] In these embodiments, the monitoring system can monitor the deformation of the roadbed 500 in real time and transmit the data to the remote control terminal for timely analysis and processing.

[0135] The remote control terminal is the hub of the entire monitoring system, responsible for receiving, storing and analyzing data from the data acquisition module 730, and issuing instructions or alarms as needed. For example, the remote control terminal can be a computer, which is manually monitored.

[0136] A plurality of deformation sensors are buried and distributed in the roadbed 500 to detect the deformation of the roadbed 500. These sensors can monitor the settlement, displacement and other deformation conditions of the roadbed in real time.

[0137] The data acquisition module 730 is electrically connected to the plurality of deformation sensors, and is responsible for collecting the detection data of each sensor and transmitting the data to the remote control terminal. The data acquisition module 730 is usually highly accurate and reliable, ensuring the accuracy and integrity of the data.

[0138] The deformation of the roadbed can be monitored in real time by the deformation sensor embedded in the roadbed 500. Once an abnormal change (such as uneven settlement or displacement) is found, the system can immediately issue an alarm to remind relevant personnel to take measures to prevent potential safety hazards.

[0139] The remote control terminal can analyze the collected data and generate detailed reports and charts to help engineers and managers better understand the status of the roadbed and make scientific and reasonable maintenance and management decisions. The real-time monitoring system can promptly detect and deal with potential problems, reduce road damage and safety hazards caused by roadbed deformation, and improve the overall safety and service life of the road.

[0140] For example, the deformation sensor uses a high-precision strain gauge or displacement sensor with good durability and anti-interference ability.

[0141] The data acquisition module 730 uses industrial-grade data acquisition equipment with high precision, high reliability and anti-interference capabilities to ensure the accuracy and integrity of the data.

[0142] The remote control terminal can be a computer system that integrates data analysis and communication functions, or it can be a management system based on a cloud platform.

[0143] During the construction process, it is necessary to bury the deformation sensors in strict accordance with the design requirements and ensure that the electrical connection between the data acquisition module 730 and the remote control terminal is stable and reliable. The specific installation steps may include: according to the design requirements, bury multiple deformation sensors at different positions of the roadbed 500 to ensure that they can cover the key areas of the entire roadbed. Install the data acquisition module 730 in a suitable position and electrically connect it to each deformation sensor to ensure the stability of data transmission. Configure the remote control terminal, set parameters such as data acquisition frequency and alarm threshold, and test the operation of the system.

[0144] Exemplarily, the deformation sensors are buried in different key positions of the road base layer 500, such as the junction of the upper road base layer 510, the buffer layer 520 and the lower road base layer 550, and below the second grid mesh 530. In this embodiment, the deformation sensor is disposed in the buffer layer 520.

[0145] like Figure 1 As shown, in some embodiments, the first grid mesh 400 and the second grid mesh 530 are respectively connected to the steel meshes of the slopes on both sides of the highway to further improve the integrity of the highway.

[0146] like Figure 1 As shown, in some embodiments, the road base layer 500 further includes a water-blocking layer 540, which is disposed at the bottom of the buffer layer 520 and located at the top of the lower road base layer 550. For example, the water-blocking layer 540 is made of a flexible water-proof geotextile, which can timely block the accumulated water above the buffer layer 520 to prevent the accumulated water from further infiltrating, and can effectively prevent the water under the ground from moving upward to cause roadbed damage.

[0147] like Figure 1 As shown, in some embodiments, a solar panel 710 and a battery 720 are additionally provided to power the entire system in daily use, mainly to power the deformation sensor buried in the roadbed 500 and the data acquisition module 730; the battery 720 stores the electricity generated by the solar panel 710 in a timely manner as a backup power source.

[0148] like Figure 1 As shown, in some embodiments, the data acquisition module 730 is electrically connected to the remote control terminal via a wireless transmission module to achieve wireless data transmission, and further cooperates with the solar panel 710 to effectively reduce the laying of cables.

[0149] like Figure 6 As shown, in some embodiments, a repair device 800 for repairing a road is further provided, the repair device 800 includes a movable body 810, and the movable body 810 is provided with:

[0150] The camera 820 is mainly used for automatic identification and positioning during the entire repairing process, and for monitoring the construction process after the position is determined, which is an important basis for the full automation of the entire system. For example, the camera 820 is an industrial camera 820.

[0151] Aggregate box 830: The main function is to store materials. It reserves materials of a certain grade according to demand for use in the later repair process.

[0152] Material transport drive system 840: The main function is to transport the material to a predetermined location for repair during the repair process of the repair structure. For example, the material transport drive system 840 is a screw conveyor or a conveyor belt, etc.

[0153] Slurry pumping system 860: The main function is to perform grouting after the gravel backfill enters the predetermined position of the buffer layer 520, and to use the adhesion of the slurry material to enhance the overall stability of the repaired part and further improve the repair strength. For example, the slurry pumping system 860 includes a slurry pump, a delivery pipeline and a storage tank, and the storage tank is connected to the delivery pipeline through the slurry pump.

[0154] Data integration control terminal 850: The main function is to automatically control the repair process, including the identification, positioning, and repair of large deformation positions of the roadbed, and transmit the data to the indoor terminal in real time. At the same time, it monitors the material situation in the aggregate box 830 and issues an alarm in time when there is a shortage of materials.

[0155] Repair shovel 870: The main function is to push the repair shovel 870 into the buffer layer 520 under the continuous advancement of the repair structure. After reaching the predetermined position, the stone is squeezed into the deformed position in the buffer layer 520 to enhance the bearing capacity of this part and prevent secondary deformation or damage in the later stage.

[0156] The data integration control terminal 850 automatically reaches the predetermined position after receiving the alarm signal from the monitoring system, and repairs the entire road and structure by repairing the buffer layer 520. The second grid mesh 530 layer in the buffer layer 520 can connect the buffer layer 520 into an integral structure during the repair process. After the repair shovel 870 lifts the entire structure, aggregates will appear at the bottom. After the aggregates enter the predetermined position, the slurry pumping system 860 performs grouting to complete the repair process. The entire process is automated, which greatly saves manpower and material resources, improves repair efficiency, and ensures the safety of construction workers.
