Description

Technical Field

[0001] The present application relates to the field of municipal road construction technology, and in particular to a municipal road paving structure with a long service life and a paving method thereof. Background Art

[0002] Municipal roads are engineering facilities for various vehicles and pedestrians to pass through, and sidewalks are mainly for pedestrians to pass through. When building sidewalks, in order to reduce the accumulation of water on the road surface during rain, permeable bricks are usually used as the pavement structure. However, after years of water seepage, the filler at the bottom of the road surface is easily moved by the infiltrated water, causing the bottom of the road surface to be easily concave, and the permeable bricks have poor flexural resistance, causing the permeable bricks to be easily broken and damaged. Summary of the invention

[0003] In order to improve the above problems, the present application provides a municipal road paving structure with a long service life and a paving method thereof.

[0004] In the first aspect, the present application provides a municipal road paving structure with a long service life, which adopts the following technical solution:

[0005] A municipal road paving structure with a long service life comprises a main layer arranged between curbstones on both sides of the road, wherein the main layer comprises, from bottom to top, a base layer, a water storage layer, a crushed stone layer, a gravel layer, a mesh layer, a buffer sand layer, a water-permeable material layer, a leveling layer and a water-permeable brick layer; a plurality of sand-fixing frames are arranged at intervals in the gravel layer, the sand-fixing frames comprise a main frame and convex tips arranged on the top and bottom surfaces of the main frame, the pores of the mesh layer are penetrated by the convex tips, and the water-permeable material layer is penetrated by the convex tips.

[0006] By adopting the above technical solution, the water storage layer stores the water that seeps under the road surface, so that the road surface remains dry; the crushed stone layer and the gravel layer have good water seepage effect and make the roadbed stable; the sand fixing frame in the gravel layer fixes the gravel so that the sand is not easily washed away by the seeping water. The convex tip at the bottom of the main frame makes the main frame difficult to move. The setting of the mesh surface layer allows the gravel to be better limited in the sand fixing frame, while the gravel can still be easily moved on the level where the convex tip on the top surface of the sand fixing frame is located, which is convenient for the gravel to be compacted in real time during use due to vibration, so as to facilitate the gravel layer to remain flat, reduce the breaking force that the seepage bricks have to resist, make the seepage bricks not easily damaged, and increase the service life of the road. The mesh surface layer is pierced and fixed by the convex tip, so that the mesh surface layer is not easy to move.

[0007] The buffer sand layer mainly separates the water-permeable fabric layer and the gravel layer. After the water-permeable fabric layer is pierced by the convex tip, the water-permeable fabric layer is not easy to move, so that the water-permeable fabric layer is not easy to be damaged. The water that penetrates into the ground mainly chooses to penetrate from the water-permeable fabric layer, and the water mainly impacts the buffer sand layer, so that the water is not easy to drive the gravel on the gravel layer to move, thereby ensuring the flatness of the surface and not easy to cause concave phenomenon. The water-permeable fabric layer has a good effect of isolating gravel, so that the gravel is not easy to lose after the water-permeable brick is damaged, keeping the road surface relatively clean, and at the same time preventing the gravel at the bottom of the damaged water-permeable brick from losing and causing the adjacent bricks to be damaged, reducing losses and facilitating maintenance; at the same time, the water-permeable fabric layer also has the function of reducing the impact of water, protecting the underlying structure, and increasing the service life of the road. The leveling layer buries the convex tip for easy compaction.

[0008] Optionally, the main frame includes an outer frame and partition rods that are evenly spaced and arranged in rows inside the outer frame.

[0009] By adopting the above technical solution and setting the dividing rods, water is divided into multiple streams and permeates downwards, thereby reducing the loss of sand and gravel.

[0010] Optionally, the distance between the edge of the side wall of the main frame where the protrusion is located and the root edge of the protrusion is greater than or equal to 1 cm.

[0011] By adopting the above technical solution, after the water-permeable fabric layer is pierced by the convex tip, water will preferentially seep up and down from the holes pierced by the convex tip on the water-permeable fabric layer. The distance between the edge of the convex tip and the edge of the mounting frame is set to be greater than or equal to 1 cm, so that the water flow will preferentially impact the top surface of the main frame after falling, thereby protecting the gravel layer and preventing the gravel from being easily lost.

[0012] Optionally, the water storage layer is formed by laying a plurality of support members, wherein the support members include a bottom plate, a top plate and load-bearing columns connecting the top plate and the bottom plate, and a plurality of seepage holes are arranged on the top plate.

[0013] By adopting the above technical solution, the gap between the top plate and the bottom plate is used to store water, so that the water storage performance of the municipal road is good and the road surface dries quickly.

[0014] In a second aspect, the present application provides a method for laying a municipal road paving structure with a long service life, using the following technical solution:

[0015] A method for laying a municipal road paving structure with a long service life, characterized in that it comprises the following steps:

[0016] S1, laying curbstones on both sides of the road and leveling the road base between the curbstones;

[0017] S2, laying the aquifer, laying a gravel layer on top of the aquifer and leveling it;

[0018] S3, laying of gravel layer, firstly lay sand fixing racks on the gravel layer, pour in coarse sand, level it for the first time, the height of the first leveling is 0.5-1cm less than the height of the tip of the convex point, and then lay the mesh surface layer;

[0019] S4, laying of the buffer sand layer, after pouring coarse sand on the mesh surface layer, perform the second leveling, the second leveling height is 0.2cm less than the tip height of the convex tip;

[0020] S5, laying a permeable fabric layer, and then laying coarse sand and compacting it as a leveling layer;

[0021] S6, laying of the permeable brick layer, bonding and laying the permeable bricks by permeable concrete.

[0022] By adopting the above technical solution, the first leveling height is 0.5-1cm less than the tip height of the convex point, which is convenient for the convex point to penetrate the mesh layer. Then the second leveling height is 0.2cm less than the tip height of the convex point, which is convenient for the convex point to penetrate the permeable fabric, so that the infiltrated water is not easy to cause the gravel on the gravel layer to move, thereby ensuring the flatness of the surface and preventing concave phenomenon from occurring.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. The sand fixing frame is set up to fix the gravel, so that the sand is not easily washed away by the infiltrating water. The sand fixing frame diverts the water flow and infiltrates, so that the gravel is not easy to lose. The convex point pierces the mesh surface layer to fix the mesh surface layer. At the same time, it also makes the mesh surface layer not easily damaged by underground activities, thereby increasing the service life of the road;

[0025] 2. The permeable fabric layer has a good effect of isolating gravel, so that gravel is not easy to lose after the permeable brick is damaged, keeping the road surface relatively clean. At the same time, it also prevents the gravel at the bottom of the adjacent bricks of the damaged permeable bricks from losing and causing the adjacent bricks to be damaged, reducing losses and facilitating maintenance;

[0026] 3. Set the distance between the convex edge and the edge of the mounting frame to be greater than or equal to 1 cm, so that the water flow will first impact the top surface of the main frame after falling, thereby protecting the gravel layer and preventing the gravel from being easily lost.
