In the drawings:

[0023] The technical solution of the present invention is further described in detail below through the accompanying drawings and embodiments.

[0024] The present invention provides a floor tile paving structure for urban and rural pedestrian walkways, such as Figure 1 to Figure 3 As shown, a preferred embodiment of the present invention is shown. The paving structure consists of two parts: floor tiles and permeable concrete. The octagonal floor tiles have the characteristics of structural stability, compression resistance and deformation resistance. The four adjacent floor tiles above, below, left and right are interlocked to achieve a stable effect and enclose a permeable area. The area is set as a permeable concrete pavement. The rainwater collected by the floor tile surface layer will be discharged downward through the permeable concrete area.

[0025] Specifically, Figure 1 As shown, the urban and rural pedestrian walkway floor tile paving structure includes regular octagonal floor tiles 1 that are spliced ​​and laid on a base layer and permeable concrete 2 that is laid in the area enclosed by four adjacent floor tiles 1.

[0026] like Figure 2 As shown, the sides of the two non-adjacent sides of the floor tile 1 are inclined from the surface layer and the bottom layer to form a protrusion 3, the highest protrusion height of the protrusion 3 is less than 1 / 8 of the length of the side, and a water guide groove is provided on the inclined surface of the protrusion 3. Preferably, the surface layer and the bottom layer of the floor tile 1 are both regular octagons, with a side length of 10 to 15 cm and a thickness of 6 to 8 cm. The depth of the water guide groove 4 is 0.3 cm, the width is 0.8 cm, and the spacing between adjacent water guide grooves 4 is 0.5 cm.

[0027] like Figure 3 As shown, one end of the protrusion 3 is inwardly depressed in a tetrahedron to form a slot 4, and the depression depth and shape of the slot 4 are the same as the protruding height and shape of the protrusion 3. The surface layer of the floor tile 1 is provided with a downward slope with a slope of 1.5-2% from the center of the regular octagon to the surrounding areas, which is conducive to the rainwater collected by the floor tile surface layer to be discharged downward through the permeable concrete area.

[0028] The right side of each protrusion is sunken inward to form a slot, and the depth and shape of the sunken groove are consistent with the height and shape of the protrusion. On the one hand, the protrusion forms a combined force through the interlocking effect of the slot when two tiles are spliced ​​together, thereby enhancing the stability of the floor tile structure. On the other hand, when the permeable concrete is poured and covered, downward and lateral pressure is formed on the protruding position of the floor tile, which plays a dual role in stabilizing the floor tile structure.

[0029] Furthermore, the floor tile 1 is formed by mixing and shaping 15% to 30% of cement, 15% to 25% of sand, 20% to 55% of aggregate, 3% to 15% of water and 0.1% to 2% of concrete admixture. The aggregate includes a first aggregate, a second aggregate, a third aggregate and a fourth aggregate. The first aggregate is a carbonized coconut shell crushed particle with a particle size of 1 to 2 cm. The retired wind turbine blade material is processed from a glass fiber reinforced thermosetting resin-based composite material, the second aggregate is a glass fiber (which may contain a small amount of resin) coarsely separated from the retired wind turbine blade by crushing and rolling, and the third aggregate is a resin composite material particle-glass fiber mixture coarsely separated from the retired wind turbine blade by crushing and rolling, with a particle size of 1 to 3 cm. The fourth aggregate is construction waste crushed to granular form, specifically, after plastic, metal and wood are screened out of construction waste, only sand, stone, concrete, etc. are retained, and crushed to particles of 1.5 to 3 cm.

[0030] Furthermore, the aggregates of the surface layer of the floor tile 1 are the third aggregate and the fourth aggregate, wherein the volume ratio of the third aggregate to the fourth aggregate is 1:(6-8), and the surface layer height is 2 cm. By adding the resin composite material (containing a small amount of glass fiber) from the retired wind turbine blades and preparing it in a reasonable proportion, the flexibility and elasticity of the floor tile surface layer are increased without affecting the firmness, thereby enhancing the walking comfort. And the surface layer does not need to be polished to a smooth mirror surface, just keep it flat and non-reflective.

[0031] The aggregates of the bottom layer of the floor tile 1 are the second aggregate and the fourth aggregate, wherein the volume ratio of the second aggregate and the fourth aggregate is 1:(10-16), and the height is 1-2 cm. The bottom layer of the brick body has higher requirements for stability. By adding construction waste and glass fiber and preparing them in a reasonable proportion, the stability of the brick body is enhanced as a whole.

[0032] The aggregates of the central layer of the floor tile 1 are the first aggregate, the second aggregate, the third aggregate and the fourth aggregate, wherein the added volume ratio of the first aggregate, the second aggregate, the third aggregate and the fourth aggregate is 1:(0.5-1):(2-3):(10-25), and the height is 3-4 cm. By adding carbonized coconut shell crushed particles, a small molecular pore structure is formed in the brick body, which increases the moisture absorption and heat absorption capacity of the brick body, and greatly alleviates the urban and rural heat island effect. By adding retired wind turbine blade fragments (including glass fiber and composite resin materials) and a reasonable proportion, the brick structure is reinforced, and the flexibility and overall stability are enhanced.

[0033] Furthermore, the base layer includes a first base layer under the floor tile 1 and a second base layer under the permeable concrete 2, the first base layer includes a soil base layer, a cement gravel layer, a concrete layer, and a dry cement mortar layer laid in sequence from bottom to top; the second base layer includes a soil base layer, a cement gravel layer, a graded gravel layer, and a coarse sand and stone layer laid in sequence from bottom to top.

[0034] The blank area adjacent to the side protruding outward of each floor tile 1 is set as the permeable concrete 2 by the enclosed area between each four adjacent floor tiles, and the gap formed by the floor tiles is filled densely. The laying thickness is the same as that of the floor tiles. The second aggregate, the third aggregate and the fourth aggregate are added to the aggregate of the permeable concrete 2, wherein the added volume ratio of the second aggregate, the third aggregate and the fourth aggregate is 1: (2.5-3): (10-20), and patterns, colors, etc. can be set on the floor tiles and the concrete structure surface layer as needed to enhance the aesthetics.

[0035] Based on the above-mentioned urban and rural pedestrian walkway floor tile paving structure, the present invention also provides an urban and rural pedestrian walkway floor tile paving method, and the urban and rural pedestrian walkway floor tile paving structure can be constructed by the following steps:

[0036] 1) Preparation work: Prepare floor tile molds according to design requirements, configure the materials required for brick making, and prepare floor tiles in the required quantity according to the quality standards of sidewalk tiles; prepare permeable concrete and caulking materials according to design requirements.

[0037] 2) The base layer is arranged in accordance with the standard for floor tiles and permeable concrete, corresponding to the upper surface floor tile area and permeable area. Preferably, for ease of construction, the first base layer and the second base layer are arranged in strips at intervals under the floor tiles 1 and permeable concrete 2, and drainage pipelines are pre-buried in accordance with the requirements for permeable paving. Attention should be paid to the gradual transition of the connection area and the integrity of the entire pedestrian walkway structure.

[0038] First base layer laying for floor tile area:

[0039] From the bottom to the surface, lay in order: level and compact the soil base, 10cm cement gravel layer, 15cm concrete layer, 2cm dry cement mortar, floor tiles

[0040] Second base laying of permeable concrete area:

[0041] From the bottom to the surface, lay the following in sequence: level and compact the soil base layer, 10cm cement gravel layer, 15cm graded gravel layer, 2cm coarse sand and gravel layer, and permeable concrete (thickness consistent with floor tiles) to maintain a smooth connection between road surfaces of different materials.

[0042] 3) When laying the surface layer, the floor tiles should be laid first, and they should be correctly spliced ​​according to the interlocking structure. The joints should be filled with cement mortar to ensure the stability of the structure between the floor tiles. After the floor tiles are spliced ​​and meet the construction standards, permeable concrete should be poured into the vacant space according to the construction standards and shaped according to the construction standards.

[0043] 4) Pedestrian walkway maintenance shall be carried out in accordance with the maintenance standards for floor tiles and permeable concrete.

[0044] 5) If the permeable area is blocked, high-pressure water washing can be used to flush the permeable area. Due to the stability of the floor tile structure, high-pressure water washing will not affect the floor tile structure.

[0045] The urban and rural pedestrian walkway floor tile paving structure of the present invention has the characteristics of beauty and comfort through the combination of octagonal floor tiles and permeable concrete. It not only organically combines the advantages and disadvantages of permeable floor tiles and ordinary concrete floor tiles, but also retains the water permeability and moisture absorption performance of permeable bricks and the high strength and solid stability of concrete floor tiles. At the same time, by adding retired wind turbine blades, construction waste, coconut shells and other materials into the floor tile material, it belongs to the recycling of solid waste resources and has the characteristics of low carbon and environmental protection, thereby generating significant ecological benefits, which is of great significance to the construction of a "resource-saving and environmentally friendly" society.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the present invention can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the present invention, which should be included in the scope of the technical solution for protection of the present invention.
