Description

Technical Field

[0001] The utility model relates to the technical field of road structures, in particular to an assembled sidewalk paving structure. Background Art

[0002] Sidewalks are an important part of the urban transportation system, aiming to provide pedestrians with a safe, continuous and comfortable walking environment.

[0003] The existing sidewalk paving structure usually uses sidewalk bricks, cement concrete, cement stabilized gravel, etc., which need to be poured or paved on site. The construction and maintenance period is long, and it is impossible to open traffic quickly. During the construction period, it not only interferes with the surrounding traffic, but also its dust and noise will affect the surrounding environment. At the same time, the soil foundation under the sidewalk usually has urban pipelines buried. With the continuous advancement of urban renewal, a large number of sidewalks need to be dug up and buried or repaired and reinforced every year. There are problems such as low efficiency of excavation or repair construction, cumbersome process, and non-reusable materials.

[0004] In addition, in order to improve the slippery condition of sidewalks on rainy days and improve the walking safety and comfort of pedestrians, permeable sidewalk paving is becoming more and more widely used. However, traditional permeable sidewalks usually use permeable bricks or permeable concrete, which mainly use the pores inside the material to penetrate water, but have the problems of poor permeability and easy clogging.

[0005] Therefore, how to improve the construction efficiency of the sidewalk pavement structure and improve the water permeability efficiency of the sidewalk pavement structure has become a technical problem that technical personnel in this field urgently need to solve. Utility Model Content

[0007] In order to achieve the above technical purpose, the utility model provides an assembled sidewalk paving structure, which is characterized by comprising a permeable surface layer, a leveling layer, a permeable layer, a permeable base layer, a waterproof layer, a cushion layer and a soil base arranged in sequence from top to bottom;

[0008] A drainage pipe is arranged in the permeable base layer;

[0009] The rainwater is collected into the permeable base layer through the permeable surface layer, the leveling layer and the permeable layer, and then discharged into the rainwater well through the drainage pipe.

[0010] Furthermore, the permeable base layer is assembled from a plurality of prefabricated base layer blocks;

[0011] Two through and mutually intersecting drainage holes are arranged at the bottom of the base prefabricated block, and the adjacent and same-direction drainage holes are connected. Drainage pipes are arranged in the plurality of drainage holes, and the drainage pipes are connected to the rainwater well in the sidewalk. The infiltrated rainwater is finally discharged into the rainwater well through the drainage pipes.

[0012] Furthermore, a hole is formed on the top of the base prefabricated block and passes through to the bottom of the base prefabricated block.

[0013] Furthermore, the permeable surface layer is assembled from a plurality of tiles;

[0014] Tenons are respectively arranged on the four side surfaces of the tiles, and adjacent tiles are interlocked and fixed by means of the corresponding tenons.

[0015] Furthermore, the leveling layer is composed of coarse sand with a particle size greater than 2 mm.

[0016] Furthermore, the permeable layer is made of permeable geotextile.

[0017] Furthermore, the waterproof layer is made of waterproof geotextile.

[0018] Beneficial effects of the utility model:

[0019] 1. Due to the above structural design, the utility model has an assembled sidewalk paving, which is simple and fast to construct, convenient and quick to dismantle and repair, and can be reused, effectively reducing the project cost and reducing the interference with the surrounding traffic and environment; the sidewalk components can be prefabricated in the factory, with high efficiency, stable and controllable quality, and no concrete pouring and maintenance are required for on-site construction, which improves construction efficiency.

[0020] 2. Use the gaps between the tiles and the holes in the prefabricated blocks of the base to achieve water permeability, so that the sidewalk can drain smoothly, which can effectively reduce blockage problems and ensure the water permeability of the sidewalk; by setting up a waterproof layer and drainage pipes, it can effectively prevent rainwater from seeping into the soil base and reduce the problem of soil base softening when exposed to water.

[0027] The concept, specific structure and technical effects of the present invention will be further described below in conjunction with the accompanying drawings to fully understand the purpose, characteristics and effects of the present invention.

[0028] Example:

[0029] like Figure 1 As shown, the assembled sidewalk pavement structure includes a permeable surface layer 1, a leveling layer 2, a permeable layer 3, a permeable base layer 4, a waterproof layer 5, a cushion layer 6 and a soil base 7 arranged in sequence from top to bottom;

[0030] A drainage pipe 8 is provided in the permeable base layer 4;

[0031] The rainwater is collected into the permeable base layer 4 through the permeable surface layer 1, the leveling layer 2 and the permeable layer 3, and then discharged into the rainwater well through the drainage pipe 8.

[0032] The main innovation of the utility model is that the sidewalk paving adopts an assembled structure, the construction is simple and fast, the dismantling and maintenance are convenient and quick, and it can be reused, which effectively shortens the construction period and reduces the project cost, and reduces the interference with the surrounding traffic and environment.

[0033] Specifically:

[0034] like Figure 2 As shown, the permeable base layer 4 is assembled from a plurality of prefabricated base layer blocks 9;

[0035] like Figure 3 As shown, two through and intersecting drainage holes 11 are provided at the bottom of the base prefabricated block 9, and the adjacent and same-direction drainage holes 11 are connected. Drainage pipes 8 are arranged in the multiple drainage holes 11, and the drainage pipes 8 are connected to the rainwater well in the sidewalk. The infiltrated rainwater is finally discharged into the rainwater well through the drainage pipes 8.

[0036] A hole 10 is provided on the top of the prefabricated base block 9 and extends to the bottom of the prefabricated base block 9. The hole 10 can be backfilled with materials such as gravel and construction waste. The hole 10 provides sufficient runoff channels for rainwater infiltration, thereby achieving rapid water permeability.

[0037] like Figure 4 and Figure 5As shown, the permeable surface layer 1 is assembled from a plurality of tiles 12; tenons 13 are respectively provided on the four side surfaces of the tiles 12, and adjacent tiles 12 are interlocked and fixed by means of corresponding tenons 13, thereby limiting the displacement of the tiles 12 and ensuring that sufficient joint gap space is formed between the tiles 12, providing sufficient runoff channels for rainwater infiltration and achieving rapid water permeability.

[0038] Furthermore, the leveling layer 2 is composed of coarse sand with a particle size greater than 2 mm, thereby ensuring the water permeability of the leveling layer 2.

[0039] The permeable layer 3 is made of permeable geotextile, which allows rainwater to seep in and prevents the coarse sand of the leveling layer from falling into the base layer.

[0040] The waterproof layer 5 is made of waterproof geotextile, which can prevent rainwater from penetrating into the soil base and reduce the softening problem of the soil base 7 when it comes into contact with water. On the other hand, it can prevent gravel, construction waste and other materials in the holes 10 of the base prefabricated blocks 9 from falling into the cushion layer 6.
