Description

Technical Field

[0001] The invention relates to the technical field of road paving, and in particular to a road paving device for traffic engineering. Background Art

[0002] Road paving equipment is a vital equipment in traffic engineering. It is used to evenly lay asphalt mixture on the road base and form a flat road surface with a certain strength through compaction. With the rapid development of social economy and the increase in traffic flow, asphalt pavement is widely used in the construction of various types of roads due to its good flatness, anti-skid performance and convenient construction. However, under the influence of long-term vehicle rolling and natural environment, rutting is prone to occur on the road surface. The formation of such rutting is mainly due to the plastic deformation of asphalt mixture under repeated heavy load and high temperature conditions, which causes the road surface to gradually sink during vehicle driving and form longitudinal grooves.

[0003] When a vehicle passes through a rutted road, the tires are easily stuck in the ruts, making it difficult to control the direction, reducing the vehicle's driving stability and increasing the risk of traffic accidents. In addition, the ruts will also have an adverse effect on the vehicle's suspension system, resulting in a poor driving experience and increased vehicle driving noise and vibration. Summary of the invention

[0017] If the intersection parameter of the road to be paved and the surrounding roads belongs to the fourth target type, the control module executes a fourth control procedure on the paving machine;

[0018] If the intersection parameters of the road to be paved and the surrounding roads belong to the fifth target type, the control module executes a fifth control procedure on the paving machine.

[0019] Further, if the intersection parameter of the road to be paved and the surrounding roads belongs to the third target type, the control module executes a third control procedure on the paving machine;

[0020] Among them, the third target type is the dead-end intersection; the third control program is used to adjust the arrangement of the compression-resistant blocks in the intersection area of ​​the road to be paved and the surrounding roads.

[0021] Furthermore, the third control procedure includes:

[0022] Obtaining a moving trajectory of the vehicle in an intersection area of ​​a third target type;

[0023] The compression-resistant blocks are set to be arranged in an arc shape in the intersection area of ​​the third target type.

[0039] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below through embodiments and in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0042] like Figure 1 As shown, an embodiment of the present invention provides a road paving device for traffic engineering, which includes an identification module, a paving machine and a control module.

[0043] The recognition module is able to obtain the specifications of the road to be paved.

[0044] Specifically, the specifications of the road to be paved can be divided according to the importance of the road to be paved, and the specifications of the road to be paved can be divided into national roads, provincial roads, county roads and township roads, etc. The specifications of the road to be paved can also be divided according to the type of vehicles traveling on the road to be paved, and the specifications of the road to be paved can be divided into first-class highways, second-class highways, third-class highways, fourth-class highways, etc. The recognition module can accurately obtain the specifications of the road to be paved according to the purpose of the road to be paved. Furthermore, when the road to be paved is planned for construction, the road to be paved has planned drawing information, and the drawing information can obtain specific information such as the width, lanes, and main uses of the road to be paved. The specifications of the road to be paved can be clarified based on the specific information in the drawing.

[0045] The paving machine can lay the substrate layer 130 on the road to be paved, and can also lay the road surface layer 150 on the substrate layer 130 ; the paving machine can set the anti-compression blocks 140 on the substrate layer 130 .

[0046] Specifically, the paving machine can first lay the substrate layer 130 on the road to be paved, wherein the substrate layer 130 is mainly used to prevent the soil of the road to be paved from settling. The substrate layer 130 can be concrete or crushed stone. The substrate layer 130 can form a whole after rolling. The substrate layer 130 can bear the weight of the pavement layer 150 and the moving vehicles. The substrate layer 130 needs to transfer these vertical loads evenly to the foundation below to prevent the road surface from being deformed or damaged due to excessive local force.

[0047] Furthermore, the laying machine can also set anti-compression blocks 140 on the substrate layer 130. When laying the anti-compression blocks 140, multiple anti-compression blocks 140 are set. The hardness of the anti-compression blocks 140 is the same as that of the substrate layer 130. The anti-compression blocks 140 are set directly above the substrate layer 130. The anti-compression blocks 140 form protrusions on the substrate layer 130. There is a gap between any two substrate layers 130. Furthermore, in order to increase the anti-compression ability of the anti-compression blocks 140 in the vertical direction, vertical steel bars are set inside the anti-compression blocks 140, thereby increasing the bearing capacity in the vertical direction.

[0048] Furthermore, the paving machine can also set a pavement layer 150 above the substrate layer 130 and the anti-compression blocks 140, wherein the pavement layer 150 is asphalt, and the upper surface of the asphalt is a plane, so as to ensure that the vehicle can drive smoothly on the pavement layer 150. Asphalt can be filled between two adjacent anti-compression blocks 140, and when the vehicle rolls on the pavement layer 150, the anti-compression blocks 140 can prevent the pavement layer 150 from deforming. At the same time, the anti-compression blocks 140 can prevent the stress concentration of the pavement layer 150, thereby reducing the probability of deformation of the pavement layer 150. Furthermore, when the anti-compression block 140 is not provided, the total contact area between the substrate layer 130 and the pavement layer 150 is the surface area of ​​the pavement layer 150. Since the anti-compression block 140 is in a raised state on the substrate layer 130, the surface area of ​​the pavement layer 150 is smaller than the contact area between the pavement layer 150 and the anti-compression block 140 plus the contact area between the pavement layer 150 and the substrate layer 130. By providing the anti-compression block 140, the stability of the pavement layer 150 is further increased.

[0049] The control module can execute a first control program on the paving machine according to the specifications of the road to be paved, and the first control program includes: formulating a classification standard for the road to be paved; if the specification of the road to be paved belongs to the first target type, adjusting the thickness of the anti-compression block 140 to the first preset thickness; if the specification of the road to be paved belongs to the second target type, adjusting the thickness of the anti-compression block 140 to the second preset thickness; wherein the classification standard for the road to be paved includes at least the type of vehicle traveling on the road to be paved.

[0050] Specifically, first, a classification standard for the roads to be paved is formulated. When the classification standard for the roads to be paved is the type of vehicles traveling on the roads to be paved, the type of vehicles traveling on the roads to be paved can be obtained according to the types of vehicles passing through similar roads in the surrounding areas, and the roads to be paved are classified into a first target type with more heavy-loaded vehicles and a second target type with fewer heavy-loaded vehicles. More heavy-loaded vehicles means that the degree of rolling on the roads to be paved is greater. At this time, the thickness of the anti-compression block 140 is adjusted to a first preset thickness. Fewer heavy-loaded vehicles means that the degree of rolling on the roads to be paved is less. At this time, the thickness of the anti-compression block 140 is adjusted to a second preset thickness, and the first preset thickness is greater than the second preset thickness. After the thickness of the anti-compression block 140 is adjusted, the degree of stress concentration of the anti-compression block 140 on the road surface layer 150 is changed. At the same time, after the thickness of the anti-compression block 140 is adjusted, the cost of laying the anti-compression block 140 is also changed. After the specifications of the roads to be paved are clarified, the thickness of the anti-compression block 140 is reasonably adjusted according to the specifications of the roads to be paved, thereby ensuring that the overall cost of constructing the roads to be paved is controlled when the roads to be paved meet the specified requirements.

[0051] The present invention provides a road paving device for traffic engineering. When it is necessary to construct a road to be paved, the direction and width range of the road to be paved are first determined. The paving machine can lay a base material layer 130 at the position of the road to be paved, and then the paving machine sets anti-compression blocks 140 on the base material layer 130, and sets a certain gap between two adjacent anti-compression blocks 140. The paving machine can lay a pavement layer 150 above the base material layer 130 and the anti-compression blocks 140. When a vehicle rolls over the pavement layer 150, the anti-compression blocks 140 can prevent the pavement layer 150 from being deformed. At the same time, the anti-compression blocks 140 can prevent the stress concentration of the pavement layer 150, thereby reducing the probability of deformation of the pavement layer 150, and further reducing the probability of rutting of the pavement layer 150. Furthermore, by obtaining the specifications of the road to be paved, wherein the specifications of the road to be paved are determined by the classification standard of the road to be paved, and the classification standard of the road to be paved is the type of vehicle traveling on the road to be paved, if the specifications of the road to be paved belong to the first target type, the thickness of the anti-compression block 140 is adjusted to the first preset thickness, and if the specifications of the road to be paved belong to the second target type, the thickness of the anti-compression block 140 is adjusted to the second preset thickness. When the paving machine is laying the anti-compression block 140, the paving machine can be controlled by the first control program in the control module, so that the thickness of the anti-compression block 140 when the paving machine is laying on the substrate layer 130 can be adjusted in time to cope with different specifications of the road to be paved, thereby ensuring that the probability of the pavement layer 150 being rutted can be reduced when the road to be paved has different specifications.

[0052] In one of the embodiments, the control module is also capable of executing a second control program on the paving machine according to the specifications of the road to be paved, and the second control program includes: if the specifications of the road to be paved belong to the first target type, adjusting the anti-compression blocks 140 to be arranged at a first preset density on the substrate layer 130; if the specifications of the road to be paved belong to the second target type, adjusting the anti-compression blocks 140 to be arranged at a second preset density on the substrate layer 130.

[0053] Specifically, first, a classification standard for roads to be paved is formulated. When the classification standard for roads to be paved is the type of vehicles traveling on the roads to be paved, the type of vehicles traveling on the roads to be paved can be obtained based on the types of vehicles passing on similar roads in the surrounding area, and the roads to be paved are classified into a first target type with more heavy-loaded vehicles and a second target type with fewer heavy-loaded vehicles. More heavy-loaded vehicles means that the degree of crushing of the roads to be paved is greater, and conversely, fewer heavy-loaded vehicles means that the degree of crushing of the roads to be paved is less.

[0054] If the specification of the road to be paved belongs to the first target type with more heavy-loaded vehicles, the second control program controls the paving machine to adjust the anti-compression blocks 140 to be arranged at a first preset density on the substrate layer 130, and the first preset density means that the number of anti-compression blocks 140 laid in the preset area is a first preset value. If the specification of the road to be paved belongs to the second target type with fewer heavy-loaded vehicles, the second control program controls the paving machine to adjust the anti-compression blocks 140 to be arranged at a second preset density on the substrate layer 130, and the second preset density means that the number of anti-compression blocks 140 laid in the preset area is a second preset value, wherein the first preset value is greater than the second preset value, that is, when the specification of the road to be paved belongs to the first target type, the number of anti-compression blocks 140 laid in the preset area is greater than the number of anti-compression blocks 140 laid in the preset area when the specification of the road to be paved belongs to the second target type. For example, when the specifications of the road to be paved belong to the first target type, the density of the compression-resistant blocks 140 set on the substrate layer 130 is 5 pieces per square meter. When the specifications of the road to be paved belong to the second target type, the density of the compression-resistant blocks 140 set on the substrate layer 130 is 3 pieces per square meter.

[0055] It can be understood that when the paving machine is laying the anti-compression blocks 140, the paving machine can be controlled by the second control program in the control module, so that the density of the paving machine when laying the anti-compression blocks 140 on the base material layer 130 can be adjusted in time to cope with the different specifications of the road to be paved, thereby ensuring that the probability of the road surface layer 150 being rolled out of ruts can be reduced when the road to be paved has different specifications. After the density of the anti-compression blocks 140 is adjusted, the degree to which the anti-compression blocks 140 hinder the stress concentration of the road surface layer 150 changes. At the same time, after the density of the anti-compression blocks 140 is adjusted, the cost of laying the anti-compression blocks 140 also changes. After the specifications of the road to be paved are clarified, the density of the anti-compression blocks 140 is reasonably adjusted according to the specifications of the road to be paved, thereby ensuring that the overall cost of building the road to be paved is controlled when the road to be paved meets the specified requirements.

[0056] In one of the embodiments, the identification module is also capable of obtaining the intersection parameters of the road to be paved and the surrounding roads, wherein the intersection parameters at least include the type of intersection area between the road to be paved and the surrounding roads; if the intersection parameters of the road to be paved and the surrounding roads belong to the third target type, the control module executes the third control program on the paving machine; if the intersection parameters of the road to be paved and the surrounding roads belong to the fourth target type, the control module executes the fourth control program on the paving machine; if the intersection parameters of the road to be paved and the surrounding roads belong to the fifth target type, the control module executes the fifth control program on the paving machine.

[0057] Specifically, when a vehicle is traveling at a constant speed on the road to be paved, each tire of the vehicle can evenly distribute the weight of the vehicle. When the vehicle brakes, accelerates, or turns, the center of gravity of the vehicle will shift, and the weight of the vehicle borne by each tire of the vehicle will change. Accordingly, the rolling force of each tire of the vehicle on the road surface layer 150 will change. When the road to be paved intersects with the surrounding roads, the road to be paved and the surrounding roads form an intersection area. Generally, in order to reduce the occurrence of traffic accidents, a traffic light is set when the road to be paved intersects with the surrounding roads. When passing through the intersection area, the vehicle generally decelerates first and then accelerates. The deceleration is to prevent sudden situations in the intersection area, and the acceleration is to quickly pass through the intersection area when there are no sudden situations in the intersection area. At this time, when the vehicle travels to the intersection area, the center of gravity of the vehicle shifts multiple times, and the degree of compression of the tires of the vehicle on the road surface layer 150 is further increased. Accordingly, in the intersection area, the probability of wrinkles in the road surface layer 150 is higher.

[0058] Furthermore, the identification module can also obtain the intersection parameters of the road to be paved and the surrounding roads, wherein the intersection parameters are the types of intersection areas between the road to be paved and the surrounding roads, and the types of intersection areas include at least dead-end intersections, cross intersections, and T-intersections. In different types of intersection areas, there are differences in the way that vehicles squeeze the pavement layer 150 when driving into the intersection area.

[0059] Furthermore, when the intersection parameters of the road to be paved and the surrounding roads belong to the third target type, the control module executes the third control program on the paving machine; if the intersection parameters of the road to be paved and the surrounding roads belong to the fourth target type, the control module executes the fourth control program on the paving machine; if the intersection parameters of the road to be paved and the surrounding roads belong to the fifth target type, the control module executes the fifth control program on the paving machine. Specifically, when the intersection parameters of the road to be paved and the surrounding roads belong to different types, the control module executes the corresponding control program on the paving machine to ensure that the paving machine adjusts the way to lay the anti-compression block 140 in the intersection area, so as to ensure that when the vehicle travels to the intersection area, the anti-compression block 140 can increase the probability of preventing the road surface layer 150 from wrinkling.

[0060] In one embodiment, if the intersection parameters of the road to be paved and the surrounding roads belong to the third target type, the control module executes a third control program on the paving machine; wherein the third target type is a dead-end intersection; the third control program is used to adjust the arrangement of the compression-resistant blocks 140 in the intersection area of ​​the road to be paved and the surrounding roads.

[0061] Specifically, the extension direction of the road to be paved and the extension direction of the surrounding roads have an angle to ensure that there is an intersection area between the road to be paved and the surrounding roads. When the road to be paved and the surrounding roads intersect at the end, when the vehicle is driving from the road to be paved to the surrounding roads, the vehicle directly enters the surrounding roads by turning left or right, and the vehicle's travel trajectory in the intersection area is a fixed route, that is, the vehicle's travel trajectory in the intersection area of ​​the road to be paved and the surrounding roads is stable. At this time, the control module executes the third control program on the paving machine to ensure that after the anti-pressure block 140 is laid in the intersection area, the vehicle can accurately roll over the anti-pressure block 140 when driving in the intersection area, so as to prevent the vehicle from rolling over the unlaid anti-pressure block 140 when passing through the intersection area.

[0062] In one of the embodiments, the third control procedure includes: obtaining a moving trajectory of the vehicle in an intersection area of ​​a third target type; and setting the anti-pressure blocks 140 to be arranged in an arc shape in the intersection area of ​​the third target type.

[0063] Specifically, the third target type is a dead-end intersection, and the vehicle's running trajectory in the intersection area is arc-shaped. The anti-compression blocks 140 are set to be arranged in an arc shape in the intersection area of ​​the third target type, thereby ensuring that the wheels of the vehicle can roll over the road surface layer 150 above the anti-compression blocks 140 when the vehicle passes through the intersection area.

[0064] In one embodiment, if the intersection parameters of the road to be paved and the surrounding roads belong to the fourth target type, the control module executes a fourth control program on the paving machine; wherein the fourth target type is a T-shaped intersection; the fourth control program is used to adjust the arrangement of the compression-resistant blocks 140 in the intersection area of ​​the road to be paved and the surrounding roads.

[0065] Specifically, when the road to be paved and the surrounding roads are T-intersected, when the vehicle passes through the intersection area, the vehicle can turn and enter the surrounding roads or continue to drive straight along the road to be paved. At this time, the control module executes the fourth control program on the paving machine to ensure that after the anti-compression blocks 140 are laid in the intersection area, the vehicle can accurately roll over the anti-compression blocks 140 when driving in the intersection area, so as to prevent the vehicle from rolling over the unlaid anti-compression blocks 140 when passing through the intersection area.

[0066] In one of the embodiments, the fourth control procedure includes: obtaining the vehicle's travel trajectory in the intersection area of ​​the fourth target type; setting the arrangement of the anti-pressure blocks 140 in the intersection area of ​​the fourth target type according to the vehicle's travel trajectory; if there is an intersection in the vehicle's travel trajectory in the intersection area of ​​the fourth target type, setting the number of anti-pressure blocks 140 at the intersection point according to the number of intersections of the vehicle's travel trajectory, and adjusting the placement direction of the anti-pressure blocks 140.

[0067] Specifically, the fourth target type is a T-junction. When a vehicle is traveling in the intersection area of ​​the fourth target type, the vehicle can turn from the surrounding road to the road to be paved, or the vehicle can turn from the road to be paved to the surrounding road. There are multiple forms of movement of the vehicle in the intersection area of ​​the fourth target type. Further, when the vehicle is traveling on the road to be paved, the vehicle can turn left to enter the surrounding road, or the vehicle can turn right to enter the surrounding road, or the vehicle continues to travel straight along the road to be paved. When the vehicle is traveling on the surrounding road, the vehicle can turn left to enter the road to be paved, or the vehicle can turn right to enter the road to be paved. Among them, there is an intersection point in the vehicle's travel trajectory in the intersection area.

[0068] Furthermore, when the vehicle travels in the intersection area, there is a straight or curved travel trajectory. Anti-compression blocks 140 are arranged in the intersection area according to the travel trajectory of the vehicle, that is, the anti-compression blocks 140 set in the intersection area are arranged in a straight line and an arc shape, thereby ensuring that the wheels of the vehicle can roll over the road surface layer 150 above the anti-compression blocks 140 when the vehicle passes through the intersection area.

[0069] Furthermore, when the vehicle is traveling in the intersection area, there is an intersection in the vehicle's travel trajectory. The number of anti-pressure blocks 140 is set at the intersection according to the number of intersections of the vehicle's travel trajectory. For easy understanding, if two travel trajectories of the vehicle intersect, two anti-pressure blocks 140 are set at the intersection, and the placement direction of the anti-pressure blocks 140 is adjusted; if three travel trajectories of the vehicle intersect, three anti-pressure blocks 140 are set at the intersection, and the placement direction of the anti-pressure blocks 140 is adjusted, thereby ensuring that the wheels of the vehicle can roll over the road surface layer 150 above the anti-pressure blocks 140 when the vehicle passes through the intersection area.

[0070] In one embodiment, if the intersection parameters of the road to be paved and the surrounding roads belong to the fifth target type, the control module executes the fifth control program on the paving machine; wherein the fifth target type is a cross intersection; the fifth control program is used to adjust the arrangement of the anti-pressure blocks 140 in the intersection area of ​​the road to be paved and the surrounding roads.

[0071] Specifically, when the road to be paved intersects with the surrounding roads at a cross, when the vehicle passes through the intersection area, the vehicle can turn to enter the surrounding roads or continue to drive straight along the road to be paved. At this time, the control module executes the fifth control program on the paving machine to ensure that after the anti-compression blocks 140 are laid in the intersection area, the vehicle can accurately roll over the anti-compression blocks 140 when driving in the intersection area, so as to prevent the vehicle from rolling over the unlaid anti-compression blocks 140 when passing through the intersection area.

[0072] In one embodiment, the fifth control procedure includes: arranging the compression-resistant blocks 140 in a matrix manner in the intersection area of ​​the fifth target type.

[0073] Specifically, since the intersection area of ​​the road to be paved and the surrounding roads is a cross intersection, the vehicle's travel trajectory in the intersection area is relatively complex. If the anti-pressure blocks 140 are laid in the intersection area according to the vehicle's travel trajectory, it is difficult to lay the anti-pressure blocks 140. At this time, the anti-pressure blocks 140 are arranged in a matrix manner in the intersection area, so that there is no situation in the intersection area where no anti-pressure blocks 140 are not laid. Further, when the anti-pressure blocks 140 are arranged in a matrix manner in the intersection area, first, the total area of ​​the intersection area is obtained, and the laying density in the intersection area is set to a first preset density, thereby obtaining the number of anti-pressure blocks 140 laid in the intersection area.

[0074] In one embodiment, the control module can adjust the thickness of the anti-compression blocks 140 laid in the first preset section of the road to be paved adjacent to the intersection area to a third preset thickness; the control module can also adjust the thickness of the anti-compression blocks 140 laid in the intersection area to the third preset thickness.

[0075] Specifically, the control module can adjust the thickness of the anti-compression blocks 140 laid in the first preset section of the road to be paved near the intersection area to the third preset thickness. It is easy to understand that the thickness of the anti-compression blocks 140 laid on the road to be paved begins to be adjusted when the road to be paved is near the intersection area. Further, the anti-compression blocks 140 of the third preset thickness are greater than the anti-compression blocks 140 of the first preset thickness. When the vehicle is near the intersection area, the vehicle will slow down. When the vehicle slows down, the degree of compression of the road surface layer 150 by the tires of the vehicle increases. By adjusting the anti-compression blocks 140 in the first preset section near the intersection area to the third preset thickness, it is prevented that the road surface layer 150 is rolled and wrinkled when the vehicle slows down to enter the intersection area.

[0076] Furthermore, the control module can also adjust the thickness of the anti-compression blocks 140 laid in the intersection area to a third preset thickness. In the intersection area, the vehicle will decelerate, accelerate, turn, etc., and the degree of compression of the vehicle's tires on the road surface layer 150 will increase. By adjusting the anti-compression blocks 140 in the intersection area to the third preset thickness, it is possible to prevent the vehicle from crushing the road surface layer 150 and causing wrinkles when driving in the intersection area.

To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
