Description

TECHNICAL FIELD

[0001] The present application relates to the field of road maintenance equipment, in particular to a road pit repair construction device with an adaptive structure and a repair construction method. BACKGROUND

[0002] Cement concrete pavement refers to the pavement with cement concrete as the main material for the surface layer, which is simply referred to as concrete pavement. Due to the increase of traffic load and the influence of pavement construction quality and other factors, the cement concrete pavement is prone to pit, crack and other diseases. Some diseases may even further deteriorate. If not maintained in time, under the coupling action of vehicle load and rainwater, the disease development speed will accelerate, and even the pavement base will be further damaged, leading to serious diseases such as serious mud pumping, wrong table, uneven settlement of the surface plate, which seriously affects the driving comfort and safety.

[0003] The current common pit repair methods for broken plate corners, broken plates and pits include filling repair and excavation repair. The repair material can be a cement-based composite repair material same as the original pavement, or an asphalt concrete repair material. The insufficient bonding force between the new material and the old material in these methods will affect the quality of the repaired road. To solve the above technical problems, patent CN114960337B discloses a three-dimensional mesh pad for repairing road pits. The two-dimensional planar network and three-dimensional nodes in the three-dimensional mesh pad provide two-dimensional and three-dimensional lateral constraints for the new repair material. The mesh and the repair material produce interlocking effect, which limits the movement of the repair material, improves the stability of the mixed material at the bonding surface and the bonding force of the contact surface, and improves the road quality and prolongs the service life of the pavement. However, the two-dimensional planar network used in this patent is a regular polygon structure. In actual application, basically all road pits are irregular. Placing the regular polygon two-dimensional planar network in the patent into the pit will inevitably cause the problem of too large spacing between the two-dimensional planar network and the inner edge of the pit, which further leads to insufficient two-dimensional and three-dimensional lateral constraints for the new repair material in this part of the spacing area. Therefore, this patent is not suitable for the treatment of concrete pavement corner fracture, broken plate and pit diseases.

[0004] Therefore, how to provide a three-dimensional mesh pad for repairing road pits that can adapt to irregular road pit shapes is a technical problem that needs to be solved by those skilled in the art. SUMMARY

[0005] The purpose of the present application is to provide a road pit repair construction device with an adaptive structure and a repair construction method to solve the problems existing in the prior art, and to realize the adaptation of the three-dimensional mesh pad to the irregular road pit shape.

[0006] To achieve the above-mentioned purpose, the present application provides the following solutions: the present application provides a cement concrete pavement pit repair construction device, which comprises:

[0007] A connecting block, one end of which extends outward to form a snap-fit ​​portion, the snap-fit ​​portion having a first mounting hole extending through the upper and lower surfaces, the other end of which is recessed inward to form a locking portion, the locking portion extending from top to bottom to form a second mounting hole; the snap-fit ​​portion of one connecting block can be snapped into the locking portion of another connecting block and the first mounting hole can correspond to the position of the second mounting hole; there are multiple sets of connecting blocks, and the multiple sets of connecting blocks have the same height, different lengths and / or widths, and the same size for the first and second mounting holes; one set of connecting blocks is snapped together end to end and laid in a circle close to the inner edge of the pit, and the remaining one or more sets of connecting blocks are laid on the inner side of the set of connecting blocks close to the inner edge of the pit;

[0008] A first connecting plate has multiple third mounting holes extending through its upper and lower surfaces. Two of the third mounting holes correspond to the positions of the second mounting holes of two different connecting blocks in two adjacent groups, and the first connecting plate is located above the connecting blocks.

[0009] The second connecting plate is detachably connected to the two adjacent first connecting plates;

[0010] The road surface engineering nail is inserted into the ground by passing through the third mounting hole, the second mounting hole, and the first mounting hole from top to bottom.

[0011] Furthermore, the second connecting plate has multiple fourth mounting holes through its upper and lower surfaces, wherein two of the fourth mounting holes correspond to the positions of the third mounting holes of two adjacent first connecting plates, and the second connecting plate is located above the first connecting plate. The road construction nail passes through the fourth mounting holes and the third mounting holes from top to bottom and is inserted into the ground.

[0012] Furthermore, the height of the connecting block is 3mm, the thickness of the first connecting plate is 1mm, and the thickness of the second connecting plate is 1mm.

[0013] Furthermore, the connecting block, the first connecting plate, and the second connecting plate are made of carbon fiber or glass fiber.

[0014] Furthermore, it also includes a support rod, the upper and lower ends of which are respectively fixedly connected to two identical connecting blocks, and the second mounting holes of the two identical connecting blocks are positioned correspondingly.

[0015] Furthermore, the height of the support rod is 2mm.

[0016] This invention also provides a method for repairing potholes in pavement with an adaptive structure, comprising the following steps:

[0017] S1: Measure the depth and extent of the pothole to confirm the deepest depth and repair area.

[0018] S2: Leveling the pits and grooves;

[0019] S3: Place multiple sets of connecting blocks into the pit from the outside in; place the first connecting plate on top of two adjacent sets of connecting blocks, so that the third mounting hole of the first connecting plate corresponds to the second mounting hole of the connecting block; insert road engineering nails, which pass through the third mounting hole, the second mounting hole, and the first mounting hole from top to bottom and are inserted into the ground;

[0020] S4: Align the two fourth mounting holes of the second connecting plate with the positions of the three mounting holes of the two adjacent first connecting plates, and insert the road construction nails from top to bottom through the fourth mounting holes and the third mounting holes and into the ground.

[0021] S5: Fill the pothole with cement concrete repair material, ensuring even spreading while filling. The height of the repair material should be 1cm to 3cm higher than the surrounding road surface. Scrape and compact the part of the repair material that is higher than the road surface.

[0022] Furthermore, step S2, which involves leveling the pit, specifically includes the following steps: leveling the bottom of the pit to its deepest point, and leveling the inner edge of the pit until the bottom and top of the pit are vertical.

[0023] Furthermore, in step S3, the process of placing multiple sets of connecting blocks into the groove from the outside in specifically includes the following steps:

[0024] Based on the pothole range confirmed in step S1, select the length and width of the first group of connecting blocks. After the first group of connecting blocks are snapped together end to end, lay them around the inner edge of the pothole. During the laying process, whenever the laying position of a connecting block in the first group is determined, align the third mounting hole of a first connecting plate with the second mounting hole of the first group of connecting blocks. Then, insert the road construction nails from top to bottom through the third mounting hole, the second mounting hole, and the first mounting hole and into the ground to pre-fix the connecting blocks until all the connecting blocks in the first group are pre-fixed. The pre-fixed connecting blocks cannot be moved, and the first connecting plate can rotate along the road construction nails.

[0025] After confirming the remaining pit area after laying the first set of connecting blocks, select the length and width of the second set of connecting blocks according to the remaining pit area. After the first and second sets of connecting blocks are snapped together end to end, lay them around the inside of the first set of connecting blocks. During the laying process, whenever the laying position of a second set of connecting blocks is determined, rotate the nearest first connecting plate to the top of the second set of connecting blocks so that the third mounting hole of the first connecting plate corresponds to the second mounting hole of the second set of connecting blocks. Then, the road construction nail is inserted from top to bottom through the third mounting hole, the second mounting hole, and the first mounting hole and into the ground to pre-fix the connecting block until all the connecting blocks of the second set are pre-fixed.

[0026] Repeat the above steps until the innermost set of connecting blocks is close to the center of the pothole. Confirm that the position of each connecting block is correct, and then drive the road surface nails deep into the ground to complete the laying of multiple sets of connecting blocks.

[0027] Furthermore, during the pre-fixing process of the road surface nails, a gap of at least 1 mm is left between the lower surface of the nail head and the upper surface of the first connecting plate.

[0028] The present invention discloses the following technical effects:

[0029] 1. Multiple sets of connecting blocks can be laid close to the inner edge according to the specific shape of the pit, which is highly adaptable to the actual pit. The small gap between the connecting block and the inner edge of the pit can avoid insufficient two-dimensional and three-dimensional lateral constraint force provided by the new repair material in the gap area.

[0030] 2. The first connecting plate, the second connecting plate, and the connecting block are located at different horizontal heights. Therefore, this application can achieve three-dimensional lateral constraints without setting three-dimensional nodes. At the same time, a two-dimensional constraint mesh is formed between the connecting block and the first connecting plate, and another two-dimensional constraint mesh is formed between the second connecting plate and the first connecting plate. Therefore, the overall three-dimensional lateral constraint force is very reliable, has strong stability and good support, and can better improve road quality and extend the service life of the road surface.

[0031] 3. Since the connecting blocks can be laid close to the inner edge of the pit, the group of connecting blocks near the inner edge of the pit can function as a two-dimensional planar mesh on the sidewall in the prior art. Therefore, this application does not require setting a two-dimensional planar mesh on the sidewall of the pit. Before repairing the pit, the bottom of the pit is leveled to its deepest depth, and the edge of the pit is leveled to a vertical state. This ensures that the outermost first group of connecting blocks can directly contact the inner edge of the pit, improving the three-dimensional lateral constraint force at the inner sidewall of the pit.

[0032] 4. Two identical connecting blocks can be fixedly connected by support rods. When multiple sets of connecting blocks are equipped with support rods, the overall height of the connected blocks after laying can be increased, adapting to various pit depths. After the support rods are installed, multiple sets of connecting blocks form a three-dimensional frame structure similar to a steel cage, which can further improve the three-dimensional lateral constraint force compared with the existing technology.

Detailed Implementation

[0040] 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.

[0041] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0042] Example 1

[0043] Reference Figures 1-3This invention provides an adaptive road pothole repair construction device, comprising: a connecting block 1, one end of which extends outward to form a locking portion 101, the locking portion 101 having a first mounting hole 1011 extending through its upper and lower surfaces; the other end of the connecting block 1 being recessed inward to form a locking portion 102, the locking portion 102 extending from top to bottom to form a second mounting hole 1021. The inwardly recessed position of the connecting block 1 is approximately located in the middle of the connecting block 1, thus forming locking portions 102 at both the upper and lower positions of the connecting block 1. Correspondingly, both the upper and lower locking portions 102 are provided with the same second mounting hole 1021; the locking portion 101 of one connecting block 1 can be locked into the locking portion 102 of another connecting block 1, and the first mounting hole 1011 can correspond to the position of the second mounting hole 1021. Figure 1 As shown, the first mounting hole 1011 is located near the left side of the snap-fit ​​part 101, and the second mounting hole 1021 is located near the right side of the engaging part 102. Therefore, when the first mounting hole 1011 and the second mounting hole 1021 are aligned, the snap-fit ​​part 101 is not fully inserted into the engaging part 102. At this time, the other connecting block 1 can be rotated to adjust the specific angle during installation while maintaining the alignment of the first mounting hole 1011 and the second mounting hole 1021. There are multiple sets of connecting blocks 1, and the height of the multiple sets of connecting blocks 1 is the same, while the length and / or width are different. The size of the first mounting hole 1011 and the second mounting hole 1021 is the same. The multiple sets of connecting blocks 1 can be prepared by proportionally reducing the size. For example, the scale of the first set of connecting blocks 1 is 1, the scale of the second set of connecting blocks 1 is 0.9, and so on. In actual use, the selection is based on the range of the pothole 6; one set of connecting blocks 1 are sequentially snapped together and laid around the inner edge of the pothole 6, and the remaining one or more sets of connecting blocks 1 are laid on the inner side of the set of connecting blocks 1 near the inner edge of the pothole 6; the first connecting plate 2 has multiple third mounting holes 201 through its upper and lower surfaces, two of which correspond to the positions of the second mounting holes 1021 of two different connecting blocks 1 in two adjacent sets, and the first connecting plate 2 is located above the connecting blocks 1; the second connecting plate 3 is detachably connected to the two adjacent first connecting plates 2; the road construction nail 4 passes through the third mounting hole 201, the second mounting hole 1021, and the first mounting hole 1011 from top to bottom and is inserted into the ground.

[0044] like Figure 3 As shown, the second connecting plate 3 has multiple fourth mounting holes 301 through its upper and lower surfaces. Two of the fourth mounting holes 301 correspond to the positions of the third mounting holes 201 of the two adjacent first connecting plates 2, and the second connecting plate 3 is located above the first connecting plate 2. The road construction nail 4 passes through the fourth mounting holes 301 and the third mounting holes 201 from top to bottom and is inserted into the ground.

[0045] In this embodiment, the height of the connecting block 1 is 3mm, the thickness of the first connecting plate 2 is 1mm, and the thickness of the second connecting plate 3 is 1mm. The connecting block 1, the first connecting plate 2, and the second connecting plate 3 are made of carbon fiber or glass fiber.

[0046] The following describes the pothole repair method in detail with reference to the cement concrete pavement pothole repair equipment disclosed in Example 1, including the following steps:

[0047] S1: Measure the depth and extent of pit 6. The specific shape of pit 6 is as follows: Figure 3 As shown, the deepest depth and repair range of the pit 6 are confirmed. In this embodiment, the deepest depth of the pit 6 is 8mm. The pit 6 is roughly rectangular in shape, with a length of about 1 meter and a width of about 0.6 meters.

[0048] S2: Level the pit 6, level the bottom of the pit 6 to the deepest depth of the pit 6, and level the inner edge of the pit 6 until the bottom and top of the pit are vertical.

[0049] S3: Select the length and width of the first set of connecting blocks 1 according to the range of the pit 6 confirmed in step S1. In this embodiment, the length of the first set of connecting blocks 1 is 0.2 meters and the width is 0.08 meters. After the first set of connecting blocks 1 are snapped together end to end, they are laid close to the inner edge of the pit 6. During the laying process, the side of the connecting block 1 is made to contact the inner side wall of the pit 6 as much as possible. Whenever the laying position of a first set of connecting blocks 1 is determined, the third mounting hole 201 of a first connecting plate 2 is aligned with the second mounting hole 1021 of the first set of connecting blocks 1. Then, the road construction nail 4 is inserted from top to bottom through the third mounting hole 201, the second mounting hole 1021, and the first mounting hole 1011 and inserted into the ground to pre-fix the connecting block 1 until all the connecting blocks 1 of the first set are pre-fixed. The pre-fixed connecting block 1 cannot be moved. There is a gap of at least 1 mm between the lower surface of the nail head of the road construction nail 4 and the upper surface of the first connecting plate 2. The first connecting plate 2 can rotate along the road construction nail 4.

[0050] After the first set of connecting blocks 1 is laid, the remaining pit 6 is roughly rectangular, with a length of about 0.8 meters and a width of about 0.4 meters. Based on the remaining pit 6, the length and width of the second set of connecting blocks 1 are selected. In this embodiment, the length of the second set of connecting blocks 1 is 0.16 meters and the width is 0.064 meters. The second set of connecting blocks 1 is sequentially snapped together end-to-end and laid close to the inner side of the first set of connecting blocks 1, forming a ring. During the laying process, whenever a second set of connecting blocks 1 is positioned, the nearest first connecting plate 2 is rotated above the second set of connecting blocks 1, aligning a third mounting hole 201 of the first connecting plate 2 with a second mounting hole 1021 of the second set of connecting blocks 1. Then, road construction nails 4 are inserted from top to bottom through the third mounting hole 201, the second mounting hole 1021, and the first mounting hole 1011, and into the ground to pre-fix the connecting blocks 1 until all the second set of connecting blocks 1 are pre-fixed. It should be noted that, as Figure 3 As shown at point A, the first and last connected blocks 1 in the first group of connected blocks 1 cannot be directly engaged via the snap-fit ​​part 101 and the engaging part 102, therefore the first connected plate 2 cannot be installed normally here. To improve structural strength, this embodiment provides a special third connected plate at this point, which is partially cut off and abuts against the last connected block 1. Figure 3 As shown at point B, due to the influence of its own size and the range of the pit, the number of the first set of connecting blocks 1 and the second set of connecting blocks 1 are not completely corresponding. Therefore, the first set of connecting blocks 1 located at point B is not connected to the second set of connecting blocks 1 through the first connecting plate 2. In the subsequent process, the road construction nails 4 can be directly inserted into the ground from the second mounting hole and the first mounting hole of the connecting block at point B.

[0051] After the second set of connecting blocks 1 is laid, the "ring" formed by the second set of connecting blocks 1 is very flat, and the gap in the middle is too small to set the third set of connecting blocks 1. It can be considered that the connecting blocks 1 are laid tightly and reach the center of the pit 6. Confirm whether the position of each connecting block 1 is correct, and drive the road construction nail 4 deep into the ground to complete the laying of multiple sets of connecting blocks 1; Connecting block 1 pit 6 first connecting plate 2 connecting block 1 first connecting plate 2 third mounting hole 201 connecting block 1 second mounting hole 1021 road construction nail 4 road construction nail 4 third mounting hole 201 second mounting hole 1021 first mounting hole 1011;

[0052] S4: Align the two fourth mounting holes 301 of the second connecting plate 3 with the positions of the three mounting holes 201 of the two adjacent first connecting plates 2, and insert the road construction nails 4 from top to bottom through the fourth mounting holes 301 and the third mounting holes 201 and into the ground; Figure 3As shown at point C, the angle between the first connecting plate 2 and the adjacent first connecting plate 2 is roughly perpendicular. If a second connecting plate 3 is provided, the second connecting plate 3 will be basically parallel to the first connecting plate 2, and a frame structure cannot be formed. Therefore, the second connecting plate 3 can be omitted here.

[0053] S5: Fill the pothole 6 with cement concrete repair material, ensuring even spreading while filling. The height of the repair material should be 1cm higher than the surrounding road surface. Scrape and compact the part of the repair material that is higher than the road surface.

[0054] Experiments have shown that the construction equipment and method for repairing potholes in cement concrete pavement disclosed in Example 1 of this application can effectively improve pavement quality and extend pavement life by more than 36%.

[0055] Example 2

[0056] like Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that it also includes a support rod 5. The upper and lower ends of the support rod 5 are fixedly connected to two identical connecting blocks 1, respectively. The second mounting holes 1021 of the two identical connecting blocks 1 correspond to each other, and the height of the support rod 5 is 2mm. In actual application, each group of connecting blocks 1 is synchronously combined and heightened using the support rod 5. Accordingly, the road construction nails 4 used should be of an extended type to ensure that the connecting blocks 1, the first connecting plate 2, and the second connecting plate 3 after the support rod 5 is installed can be smoothly fixed. The height of the repair material is 2.3cm higher than the surrounding road surface.

[0057] Experiments have shown that the cement concrete pavement pothole repair equipment disclosed in Example 2 of this application can effectively improve pavement quality and extend pavement life by more than 58%.

[0058] In other embodiments, multiple support rods 5 can be provided to fix multiple identical connecting blocks 1 together, thereby combining and increasing the height of the connecting blocks 1 as a whole, which greatly improves the range of depths of the pits 6 that can be adapted. If the pits 6 are deep, the height of the support rods 5 can be appropriately increased to reduce the number of connecting blocks 1 and the repair cost. This method will not significantly reduce the overall three-dimensional lateral constraint force.

[0059] Example 3

[0060] The difference between this embodiment and embodiment 1 is that when more than two sets of connecting blocks 1 are used, the third set of connecting blocks 1 and the second set of connecting blocks 1 are still connected by the first connecting plate 2. The first connecting plate 2 between the third set of connecting blocks 1 and the second set of connecting blocks 1 can be stacked on the first connecting plate 2 between the first set of connecting blocks 1 and the second set of connecting blocks 1, so that the two third mounting holes 201 correspond (generally, 2-4 sets of connecting blocks 1 can completely cover the pit, this method will increase the thickness of the first connecting plate 2 by an extra layer but does not affect the overall repair construction quality), or the third set of connecting blocks 1 is not connected to the second set of connecting blocks 1 but is connected to the fourth set of connecting blocks 1, the connection method is the same as the connection method between the first set of connecting blocks 1 and the second set of connecting blocks 1.

[0061] This invention discloses a repair equipment and method for potholes 6 in cement concrete pavements. Multiple sets of connecting blocks 1 can be laid close to the inner edge according to the specific shape of the pothole 6, exhibiting strong adaptability to actual potholes 6. The small spacing between the connecting blocks 1 and the inner edge of the pothole 6 avoids insufficient two-dimensional and three-dimensional lateral constraint forces provided by the new repair material in the gap area. The first connecting plate 2, the second connecting plate 3, and the connecting blocks 1 are located at different horizontal heights, thus this application can achieve three-dimensional lateral constraint without setting three-dimensional nodes. Simultaneously, a two-dimensional constraint mesh is formed between the connecting blocks 1 and the first connecting plate 2, and another two-dimensional constraint mesh is formed between the second connecting plate 3 and the first connecting plate 2. Therefore, the overall three-dimensional lateral constraint force is highly reliable, stable, and provides good support, which can better improve road quality and extend pavement service life. Since the connecting blocks 1 can be laid close to the inner edge of the pothole 6, a set of connecting blocks 1 near the inner edge of the pothole 6 can function as a two-dimensional planar mesh located on the sidewall in the prior art. Therefore, this application does not require setting a two-dimensional planar mesh on the sidewall of the pothole 6. Before repairing the pit 6, the bottom of the pit 6 is leveled to its deepest point, and the edges of the pit 6 are leveled to a vertical position. This ensures that the outermost first set of connecting blocks 1 can directly contact the inner edge of the pit 6, improving the three-dimensional lateral constraint force at the inner wall of the pit 6. Two identical connecting blocks 1 can be fixedly connected by support rods 5. When multiple sets of connecting blocks 1 are equipped with support rods 5, the overall height of the laid connecting blocks 1 can be increased to accommodate various pit depths. After adding support rods 5, multiple sets of connecting blocks 1 form a three-dimensional frame structure similar to a steel cage, which further improves the three-dimensional lateral constraint force compared to existing technologies.
