Description

Technical Field

[0001] The present invention relates to the technical field of municipal road construction, and in particular to a highly durable and crack-resistant roadbed. Background Art

[0002] Municipal roads include motor vehicle lanes, non-motor vehicle lanes, sidewalks, etc. Usually, the motor vehicle lanes are mostly referred to.

[0003] On the motor vehicle lanes of highways or on the express lanes beside some residential houses, walls are usually built on both sides to block noise and also to block the flying gravel during driving. In particular, such walls must be provided for underpass roads, which not only play the role of blocking noise and gravel, but also support the upper layer of the road as a supporting roadbed. However, the flying gravel is easy to scratch the paint on the wall surface. To maintain the urban appearance and beauty, the paint on the wall surface usually needs to be repaired regularly. When there are some severe impacts, although the cement is hard, some potholes will inevitably appear, all of which need on-site construction repair. During the construction, the road needs to be occupied, which is more inconvenient and takes more time. Summary of the Invention

[0004] To solve the problems that the flying gravel is easy to scratch the paint on the wall surface, when there are some severe impacts, although the cement is hard, some potholes will inevitably appear, affecting the durability of the roadbed, and all of them need on-site construction repair, which is more inconvenient and takes more time and affects traffic, the present application provides a highly durable and crack-resistant roadbed, and the specific solution is as follows.

[0005] A highly durable and crack-resistant roadbed includes an upper roadbed and a lower roadbed. A plurality of support walls are arranged between the upper roadbed and the lower roadbed. The upper end of the support wall is fixedly connected to the upper roadbed, and the lower end of the support wall is fixedly connected to the lower roadbed. An installation frame is arranged on the side wall of the support wall. The installation frame surrounds the support wall. A plurality of protection plates are arranged on the installation frame. The protection plates are detachably connected to the installation frame. The protection plates can completely cover the support wall. Honeycomb aluminum is embedded in the protection plates. Positioning strips are arranged on the installation frames on the left and right sides of the protection plates. Embedding grooves corresponding to the positions and shapes of the positioning strips are arranged on the protection plates. A plurality of positioning studs are arranged in the positioning strips. The positioning studs are threadedly connected to the positioning strips and cannot be removed from the positioning strips. Positioning rods corresponding to the positioning bolts are also arranged in the positioning strips. The positioning rods are slidably connected to the positioning strips. The positioning studs are arranged perpendicular to the positioning rods. Positioning grooves are opened on both sides of the embedding grooves corresponding to the positioning rods. When the positioning studs move, they can push the positioning rods to move towards the positioning grooves.

[0006] By adopting the above technical solutions, the setting of the supporting wall can effectively separate the upper and lower layers of the roadbed, ensuring the stability of the road structure. The detachable design of the protection board facilitates installation and maintenance. At the same time, the embedding of honeycomb aluminum improves the strength and sound insulation performance of the protection board. The cooperation between the positioning strip and the embedding groove realizes the precise positioning of the protection board, and the linkage structure of the positioning stud and the positioning rod ensures that the protection board is firmly fixed and prevents loosening. Moreover, with this installation method, there is no need to carry various installation materials such as bolts additionally when disassembling and installing the protection board. Just by adjusting the positioning bolts set on the positioning strip, the convenience and efficiency of installation can be improved, and the impact on traffic can be reduced.

[0007] Optionally, a return spring is arranged on the positioning rod. One end of the return spring is fixedly connected to the positioning rod, and the other end of the return spring is fixedly connected to the positioning strip. The return spring has a tendency to pull the positioning rod towards the positioning strip.

[0008] By adopting the above technical solutions, the setting of the return spring enables the positioning rod to automatically reset when not under external force, and the protection board can be removed more smoothly when the protection board is removed, further improving the convenience of disassembly and assembly. And the tendency of the return spring to pull the positioning rod towards the positioning strip can ensure that the positioning rod always maintains a stable state when not pushed by the positioning stud, reducing the problem of loosening of the positioning rod caused by vibration or other external forces, thereby enhancing the connection stability between the protection board and the mounting frame. When the protection board is installed, the return spring can also play a damping effect to a certain extent.

[0009] Optionally, a conical member is arranged at one end of the positioning stud. The conical member is fixedly connected to the positioning stud. The conical member can abut against the positioning rod, and the cross-sectional area of the conical member near the positioning rod is smaller than the end far from the positioning rod.

[0010] By adopting the above technical solutions, the setting of the conical member enables the positioning stud to more conveniently push the positioning rod to move when rotating, so as to realize the quick locking of the positioning rod and the positioning groove. The cross-sectional area of the conical member near the positioning rod is smaller than the end far from the positioning rod. This structural design reduces the initial resistance when the conical member contacts the positioning rod, improving the convenience of operation. In addition, this design effectively improves the stability and reliability during the installation process of the protection board.

[0011] Optionally, anti-slip lines are arranged on the conical member corresponding to the positioning rod, and the anti-slip lines are used to increase the friction between the conical member and the positioning rod.

[0012] By adopting the above technical solutions, the anti-slip patterns provided on the conical member can effectively increase the friction force between the conical member and the positioning rod, thereby reducing the slipping phenomenon when the conical member pushes the positioning rod and improving the stability and reliability of the movement of the positioning rod. In addition, the design of the anti-slip patterns can also ensure the firmness of the positioning rod in the positioning groove, further enhancing the stability of the installation of the protection plate.

[0013] Optionally, each of the positioning rods is provided with an arc surface, and the arc surfaces can abut against each other correspondingly.

[0014] By adopting the above technical solutions, the provision of the arc surfaces enables the positioning rods to come into contact and separate more smoothly when they abut against each other, effectively reducing the wear between the positioning rods. At the same time, the design of the arc surfaces helps the positioning rods to distribute stress evenly when subjected to external forces, thereby improving the stability and reliability of the overall structure.

[0015] Optionally, a plurality of the protection plates are vertically arranged along the mounting frame. The protection plate is provided with a lapping plate facing another protection plate, and the other protection plate is correspondingly provided with the same lapping plate. Lapping grooves are formed on the lapping plates, and the lapping plates can be mutually inserted into the lapping grooves of the corresponding lapping plates.

[0016] By adopting the above technical solutions, the protection plates are connected to each other by providing lapping plates and lapping grooves, and the lapping grooves formed on the lapping plates can make the two protection plates fit tightly. This structure not only improves the connection stability between the protection plates, but also makes the installation of the protection plates more convenient, reducing the possible misalignment problems during the installation process. At the same time, this design helps to form a complete protection barrier, effectively shielding the supporting wall and enhancing the overall aesthetics and protection effect.

[0017] Optionally, an expansion core is arranged between the lapping plates. The expansion core is arranged in the lapping groove and is used to abut against the lapping plates on both the upper and lower sides, and the expansion core can expand when heated.

[0018] By adopting the above technical solutions, the expansion core is arranged in the lapping groove and is used to abut against the lapping plates on both the upper and lower sides, making the connection between the protection plates tighter. When the ambient temperature rises, the expansion core expands when heated, further enhancing the sealing performance between the lapping plates, effectively preventing the two lapping plates from contacting and expanding due to heat and being damaged, and at the same time improving the tightness of the connection between the lapping plates.

[0019] Optionally, a flexible enclosure is wrapped around the outer side of the expansion core, and the flexible enclosure is fixedly connected to the expansion core.

[0020] By adopting the above technical solutions, the flexible enclosure can protect the expansion core and prevent it from being damaged externally during transportation or installation. At the same time, the flexible enclosure makes the contact between the expansion core and the lapping plate softer, reducing material wear caused by hard contact. In addition, the flexible enclosure can also adapt to the volume change of the expansion core during thermal expansion, ensuring that the expansion core can function properly without being affected by external constraints during the expansion process.

[0021] Optionally, a deformation groove is further provided on the protective plate. The deformation groove is opened beside the lapping groove, and the protective plate can be bent along the deformation groove.

[0022] By adopting the above technical solutions, the deformation groove endows the protective plate with a certain degree of flexibility, enabling it to bend along the deformation groove under the action of external pressure or vibration, thereby effectively alleviating the damage to the overall structure of the protective plate caused by external impact forces. This design not only improves the impact resistance of the protective plate but also extends its service life. In addition, the deformation groove is located beside the lapping groove, reducing the influence of the expansion core on the protective plate during expansion.

[0023] Optionally, a cement partition is provided on the upper roadbed, and the same mounting brackets and protective plates are also provided on the cement partition.

[0024] By adopting the above technical solutions, the effect of setting the mounting brackets and protective plates on the cement partition of the upper roadbed is achieved. This design enables the cement partition area to have the same protective function as the lower roadbed, further enhancing the safety and aesthetics of the entire municipal road, while ensuring the consistency and integrity of the road structure.

[0025] In summary, the present application has at least the following beneficial effects: 1. The present application solves the problem that flying gravel is likely to scratch the paint on the wall surface. To maintain the urban appearance, the paint on the wall surface usually needs to be repaired regularly. When there are some severe impacts, although the cement is hard, there will inevitably be some small pits, which all require on-site construction repair, which is relatively inconvenient and time-consuming and affects traffic. By setting a protective plate with honeycomb aluminum on the outer side of the supporting wall and adopting a detachable connection method, it can not only effectively resist external impact and corrosion but also facilitate quick replacement and maintenance, significantly improving the safety and durability of the supporting wall.

[0026] 2. The present application can effectively compensate for the gap generated by thermal expansion and contraction by setting lapping plates and expansion cores between the protective plates, further improving the stability and adaptability of the overall structure.

[0031] The following further details this application through specific embodiments in conjunction with the accompanying drawings.

[0032] A highly durable and crack-resistant roadbed, as Figure 1 and Figure 2 shown, includes an upper roadbed 1 and a lower roadbed 2. A plurality of support walls 3 are arranged between the upper roadbed 1 and the lower roadbed 2. The upper end of the support wall 3 is fixedly connected to the upper roadbed 1, and the lower end of the support wall 3 is fixedly connected to the lower roadbed 2. In specific implementation, a carbon reduction type pavement base material gradation design method is adopted, and industrial solid waste is used to replace traditional Portland cement, thereby improving the strength of the carbon reduction type pavement base and reducing the cracking situation that is likely to occur in the carbon reduction type pavement due to the need to set up a underpass road.

[0033] As Figure 1 and Figure 2 shown, a mounting frame 31 is arranged on the side wall of the support wall 3. The mounting frame 31 surrounds the support wall 3. A plurality of protection plates 32 are arranged on the mounting frame 31. The protection plates 32 are detachably connected to the mounting frame 31. The protection plates 32 can completely cover the support wall 3. Honeycomb aluminum is embedded inside the protection plates 32. In specific implementation, the honeycomb aluminum can effectively improve the strength of the protection plates 32. When impacted, the protection plates 32 can reduce the damage situation. When the protection plates 32 are damaged, they only need to be removed for replacement.

[0034] As Figure 2 and Figure 3As shown in the figure, positioning strips 311 are provided on the mounting brackets 31 on both the left and right sides of the protective plate 32. Embedding grooves 321 are provided on the protective plate 32 corresponding to the positions and shapes of the positioning strips 311. A plurality of positioning studs 312 are provided in the positioning strips 311. The positioning studs 312 are threadedly connected to the positioning strips 311 and cannot be removed from the positioning strips 311. Positioning rods 313 are also provided in the positioning strips 311 corresponding to the positioning bolts. The positioning rods 313 are slidably connected to the positioning strips 311. The positioning studs 312 are arranged perpendicular to the positioning rods 313. Positioning grooves 322 are provided in the two side positions of the embedding grooves 321 corresponding to the positioning rods 313. When the positioning studs 312 move, they can push the positioning rods 313 to move towards the inside of the positioning grooves 322. During specific implementation, the positioning rods 313 are respectively arranged on both sides of the positioning studs 312. When the positioning studs 312 move towards the middle of the positioning rods 313, the positioning rods 313 can move towards the positioning grooves 322 on both sides of the positioning strips 311. When the positioning rods 313 are embedded in the positioning grooves 322, the positioning studs 312 can lock the positioning rods 313. By the cooperation of the positioning rods 313 and the positioning grooves 322, the protective plate 32 can be locked, making disassembly and assembly more convenient.

[0035] As Figure 2 and Figure 3 shown, a return spring 314 is provided on the positioning rod 313. One end of the return spring 314 is fixedly connected to the positioning rod 313, and the other end of the return spring 314 is fixedly connected to the positioning strip 311. The return spring 314 has a tendency to pull the positioning rod 313 to move towards the positioning strip 311. During specific implementation, when the positioning studs 312 are withdrawn from between the positioning rods 313, the positioning rods 313 can be withdrawn from the positioning grooves 322 under the pulling of the return spring 314, making it more convenient to remove the protective plate 32 and improving the convenience of disassembly and assembly.

[0036] As Figure 2 and Figure 3 shown, a conical part 315 is provided at one end of the positioning stud 312. The conical part 315 is fixedly connected to the positioning stud 312. The conical part 315 can abut against the positioning rod 313. The cross-sectional area of the end of the conical part 315 close to the positioning rod 313 is smaller than the end far from the positioning rod 313. Anti-slip lines 316 are provided on the conical part 315 corresponding to the positioning rod 313. The anti-slip lines 316 are used to increase the friction between the conical part 315 and the positioning rod 313. Arc-shaped surfaces 317 are provided on each of the positioning rods 313. The arc-shaped surfaces 317 can abut against the arc-shaped surfaces 317 of the corresponding positioning rods 313. During specific implementation, the cooperation of the arc-shaped surfaces 317 and the conical part 315 can more effectively push the positioning rods 313 towards both sides from between the positioning rods 313, and the anti-slip lines 316 can reduce the slipping situation, further improving the stability during and after installation.

[0037] As Figure 2 andFigure 3 As shown, a plurality of protective plates 32 are vertically arranged along the mounting frame 31. The protective plate 32 is provided with a lapping plate 323 facing another protective plate 32. The same lapping plate 323 is correspondingly arranged on the other protective plate 32. Lapping grooves 324 are formed on the lapping plates 323. The lapping plates 323 can be mutually embedded into the lapping grooves 324 of the corresponding lapping plates 323. An expansion core 325 is arranged between the lapping plates 323. The expansion core 325 is arranged in the lapping groove 324 and is used for abutting against the lapping plates 323 on both the upper and lower sides. The expansion core 325 can expand when heated. A flexible enclosure 326 is wrapped around the outer side of the expansion core 325. The flexible enclosure 326 is fixedly connected to the expansion core 325. In specific implementation, the expansion core 325 can serve as a support between the lapping plates 323 and can also improve the connection tightness between the protective plates 32 when the temperature rises.

[0038] As Figure 2 and Figure 3 shown, a deformation groove 327 is also formed on the protective plate 32. The deformation groove 327 is formed beside the lapping groove 324. The protective plate 32 can be bent along the deformation groove 327. In specific implementation, when the protective plate 32 expands due to heat, the deformation groove 327 can provide a certain deformation space, and when the expansion core 325 expands, it can also provide a deformation space.

[0039] As Figure 1 shown, a cement partition 11 is arranged on the upper layer of the roadbed 1. The same mounting frame 31 and protective plate 32 are also arranged on the cement partition 11.

[0040] Working principle: By arranging a protective plate 32 with honeycomb aluminum on the outer side of the support wall 3 and adopting a detachable connection method, it can not only effectively resist external impacts and corrosion, but also facilitate quick replacement and maintenance, significantly improving the safety and durability of the support wall 3.

[0041] The above is the preferred embodiment of the present application. It does not limit the protection scope of the present application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
