Description

Technical Field

[0001] The present application relates to the field of municipal roads, and in particular to a municipal road paving structure and a paving method thereof. Background Art

[0002] Municipal engineering is an urban infrastructure construction project that serves the supporting facilities used by residents in their daily lives, such as municipal pipelines, municipal roads, greening facilities, etc. Municipal roads are mainly composed of carriageways and sidewalks, and are mainly used to provide transportation within the city and pedestrian walking. Sidewalk pavements using permeable bricks as the surface layer have become very popular.

[0003] For example, the invention patent with patent announcement number CN112211056B discloses a municipal road paving structure and a paving method thereof, which includes a base layer and curbstones arranged on the edges of both sides of the base layer. The curbstones are laid along the length direction of the sidewalk. The base layer is located between the two curbstones and a rectangular mesh frame is laid. The rectangular mesh frame includes a bottom plate laid on the base layer and long side plates vertically arranged on the edges of the two long sides of the bottom plate. The long side plates are against the side walls of the curbstones. A number of partitions are vertically arranged on the base plate and evenly spaced along its length direction. The two ends of the partition are respectively connected to the two long side plates. A accommodating groove for laying seepage bricks is formed between two adjacent partitions. A plug-in piece for plugging into the two ends of the seepage bricks is vertically inserted between the two adjacent partitions.

[0004] When using the above-mentioned municipal road paving structure, when laying the partitions, since the same spacing distance must be maintained between each partition, the laying position of the partitions needs to be measured when laying the partitions. This operation is relatively troublesome and needs to be improved. Summary of the Invention

[0005] In order to improve the problem that it is troublesome to measure the laying position of the partitions when laying the partitions, the present application provides a municipal road paving structure and a paving method thereof.

[0006] In a first aspect, the present application provides a municipal road paving structure, which adopts the following technical solution:

[0007] A municipal road paving structure comprises a base layer and curbstones arranged on both sides of the base layer, wherein the base layer is provided with a rectangular mesh frame between two curbstones, wherein the rectangular mesh frame comprises a bottom plate arranged on the base layer, long side plates arranged on the bottom plate, and a plurality of splicing plates, wherein the bottom plate is provided with drainage holes, the long side plate is located along one long side edge of the base plate, and the plurality of splicing plates are distributed along the length direction of the long side plate and in a direction perpendicular to the length direction of the long side plate;

[0008] The L-shaped plate has an L-shaped portion which is located at the side of the L-shaped plate away from the first plug-in block, and the L-shaped plate has an L-shaped portion which is located at the side of the L-shaped plate away from the first plug-in block.

[0009] By adopting the above technical solution, when building a rectangular mesh frame, the dovetail block is slid into the slide groove to realize the installation of the splicing plate, and then the plug block 1 on the splicing plate is inserted into the groove / slot 1, and the plug block 2 on the splicing plate is inserted into the slot 2 on the adjacent splicing plate. Repeat the operation to complete the construction of the rectangular mesh frame. Since the splicing plates have the same size, after the rectangular mesh frame is built, the size of the obtained accommodating groove can be guaranteed to be the same, without the need for measurement, making road paving more convenient.

[0010] When building the two ends of the rectangular mesh frame along the length direction, the plug block 1 on the L-shaped plate 1 is inserted into the groove at the end of the long side plate, and the L-shaped plate 2 corresponding to the above-mentioned L-shaped plate 1 is inserted into the slot 2 on the splicing plate at the other end of the long side plate, so that the size of the accommodating grooves at both ends of the long side plate is consistent with the size of the accommodating grooves at the middle of the long side plate, so that only one size of permeable bricks needs to be prepared, and there is no need to equip molds of other sizes to prepare permeable bricks of different sizes, which is conducive to reducing costs. Moreover, through the separate setting of the L-shaped plate 1 and the L-shaped plate 2, when building the ends of the rectangular mesh frame, there is no need to cut the splicing plate, making it more convenient to build the rectangular mesh frame.

[0011] Optionally, the leveling layer includes a crushed stone cushion layer laid on the base plate and a coarse sand layer laid on the crushed stone cushion layer.

[0012] Optionally, the water-permeable brick includes an upper brick body and a lower brick body, and the upper brick body is located above the lower brick body.

[0013] By adopting the above technical solution, the permeable bricks are arranged into upper and lower parts. Since the upper brick body is located above the lower brick body, the upper brick body will be crushed by motor vehicles and non-motor vehicles and will break before the lower brick body. When it is crushed by motor vehicles and non-motor vehicles again in the future, the broken upper brick body will squeeze the leveling layer through the lower brick body, thereby reducing the problem of local squeezing of the coarse sand layer after the permeable brick breaks, causing the coarse sand layer to sink, and then causing potholes on the road surface to affect driving safety.

[0014] Optionally, a convex edge is provided on the upper brick body, and the convex edge is located above the splicing plate and is arranged around the outer circumference of the upper brick body.

[0015] By adopting the above technical solution, a convex edge is provided, and the convex edge abuts the splicing plate to cover the gap outlet between the seepage brick and the side wall of the accommodating tank, which is beneficial to reduce the loss of coarse sand through the gap between the seepage brick and the side wall of the accommodating tank.

[0016] Optionally, a limiting block is provided on one side of the L-shaped plate 1 and the L-shaped plate 2 facing away from each other, the limiting block is located in the accommodating groove, and a limiting groove for accommodating the limiting block is opened on the lower brick body.

[0017] By adopting the above technical solution, a limit block and a limit groove are set, and the lower brick body is limited by the limit block abutting the inner wall of the limit groove. When the broken upper brick body squeezes the lower brick body, the lower brick body can move downward smoothly without tilting, further suppressing the formation of depressions in the coarse sand layer.

[0018] Optionally, retaining walls are formed by pouring concrete at both ends of the two curbstones along the length direction, and the rectangular mesh frame is installed between the two retaining walls.

[0019] By adopting the above technical solution, the construction of the retaining wall can improve the stability of the rectangular mesh frame installation.

[0020] In a second aspect, the present application provides a method for laying a municipal road paving structure, which adopts the following technical solution:

[0021] A method for laying the above-mentioned municipal road paving structure comprises the following steps:

[0022] S1. Lay curbstones and level and compact the base layer;

[0023] S2, install the bottom plate and the long side plate, move the L-shaped plate 1 so that the dovetail block slides and fits into the slide groove to realize the splicing of the L-shaped plate 1 and the L-shaped plate 2, then insert the plug-in block 1 on the spliced ​​splicing plate into the groove / slot 1, and insert the plug-in block 2 into the slot 2 on the adjacent splicing plate, repeat the above operation to complete the construction of the rectangular net frame, when constructing the two ends of the rectangular net frame along the length direction, insert the plug-in block 1 on the L-shaped plate 1 into the groove at the end of the long side plate, and insert the L-shaped plate 2 corresponding to the above L-shaped plate 1 into the slot 2 on the splicing plate at the other end of the long side plate, and then lay the leveling layer in the accommodating groove;

[0024] S3. Lay permeable bricks on the leveling layer.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. The rectangular frame is constructed by splicing long side panels and several splicing panels. Since the splicing panels have the same size, the resulting accommodating grooves are guaranteed to have the same size after the rectangular frame is constructed, eliminating the need for measurement and making road paving more convenient. Furthermore, the separate arrangement of the first and second L-shaped panels eliminates the need to cut the splicing panels when constructing the ends of the rectangular frame, making the construction of the rectangular frame even more convenient. There is no need to equip molds of different sizes to produce permeable bricks of different sizes, which helps reduce costs.

[0027] 2. By setting the permeable bricks into upper and lower parts, the problem of local squeezing of the coarse sand layer after the permeable bricks break, causing the coarse sand layer to sink, and then causing potholes on the road surface that affect driving safety, is reduced;

[0028] 3. By providing a convex edge and abutting the splicing plate through the convex edge, the gap outlet between the seepage brick and the side wall of the accommodating tank is covered, which is helpful to reduce the loss of coarse sand through the gap between the seepage brick and the side wall of the accommodating tank.
