Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The embodiment discloses a sidewalk structure, as shown in fig. 1, including a roadbed layer 1, a cement mortar layer 2, a pavement layer 3, and a curb 4 buried at one side of the pavement layer 3 along the length direction of the sidewalk. Wherein the pavement layer 3 is composed of a lower brick layer 32 and an upper brick layer 31 which are sequentially paved on the cement mortar layer 2.

As shown in fig. 1 and 2, the lower brick layer 32 is formed by mutually splicing and laying a plurality of base bricks 321, the base bricks 321 are in the shape of a geometric body left after a conical body with a downward tip is dug at each of four corners of the upper end surface of a regular quadrangular prism, and the four dug conical bodies are all straight quadrangular pyramids with a square bottom surface (the straight quadrangular pyramids with the square bottom surface are obtained by cutting the bottom surface of one regular quadrangular pyramid into four squares along the center line). The straight edge of the right rectangular pyramid coincides with one side edge of the right rectangular prism, and the side length of the bottom surface of the right rectangular pyramid is half of the side length of the bottom surface of the base brick 321, so that the top of the base brick 321 forms a roof similar to two crossed arrangements, and a groove formed by splicing the four base bricks 321 by taking any one angle as the center is a tabling groove 322 matched with the paving brick 311.

As shown in fig. 2 and 3, the upper brick layer 31 is formed by fitting a plurality of tiles 311 into the fitting groove 322, and the tiles 311 include a fitting portion 3111 that is completely fitted into the fitting groove 322 and a step portion 3112 that is integrally formed at the upper end of the fitting portion 3111. The fitting portion 3111 is a rectangular pyramid having the same shape as the fitting groove 322, the step portion 3112 is a rectangular parallelepiped having a bottom surface extending upward, and the fitting portion 3111 and the step portion 3112 are integrally cast. When the upper brick layer 31 is subjected to a vertically downward force, the bottom of the stressed paving brick 311 is abutted against the inner wall of the embedding groove 322, the vertically downward force can be dispersed towards the inner wall of the embedding groove 322, and then the four base bricks 321 forming the embedding groove 322 transmit the component force in the horizontal direction to the periphery by extruding other base bricks 321, so that the pavement layer 3 can bear heavy pressure without sinking, and the pavement layer 1 is prevented from deforming to generate pits. Moreover, since the fitting portion 3111 is completely fitted into the fitting groove 322, when the fitting portion 3111 is fitted into the fitting groove 322, the adjacent stepping portions 3112 can be engaged with each other substantially without a gap, so that the pedestrian can walk on the upper brick layer 31 more smoothly and comfortably. And four base bricks 321 extrude the laminating from four even directions and the bottom of the blanket brick 311, make the upper brick layer 31 have good steadiness, and the blanket brick 311 bottom is the taper, compares that the positive and negative is planar current ceramic tile, has good structural strength, is difficult for breaking.

As shown in fig. 2 and 3, when the base bricks 321 receive the horizontal component force dispersed by the covering bricks 311, other base bricks 321 are pressed all around, and if the arrangement between the base bricks 321 is not compact enough, four base bricks 321 directly stressed are displaced all around, so that the fitting grooves 322 are enlarged, and the covering bricks 311 sink. Therefore, the treading part 3112 higher than the highest point of the base brick 321 is arranged, so that the base brick 321 is prevented from being directly stressed after the paving brick 311 sinks, and the force cannot be dispersed all around; if the floor tile 311 sinks due to a long-term force, a certain gap may be formed between the step portion 3112 of the floor tile 311 and the adjacent step portion 3112, or between the fitting portion 3111 and the fitting groove 322. In order to avoid water accumulation between the paving brick 311 and the embedding groove 322, a transversely extending and through drainage groove 3211 is formed on two side walls of the base brick 321 perpendicular to the sidewalk direction in a pouring manner, and the drainage grooves 3211 on the two side-by-side base bricks 321 are communicated with each other; and a through groove 3212 which penetrates upward and communicates with the drain groove 3211 downward is integrally formed on each of the four side edges of the base brick 321. In rainy days, rainwater enters the gap, flows to the bottom of the fitting groove 322 along the gap between the tiling brick 311 and the fitting groove 322, and enters the drainage groove 3211 through the holes formed by the four through grooves 3212 to be discharged.

As shown in fig. 3, a drain hole 3113 is integrally formed at the center of the upper end surface of the step portion 3112 and communicates downward with the through groove 3212, and the drain hole 3113 can enhance the drainage effect of the road surface.

As shown in fig. 1 and 2, since the curb 4 is disposed in a sidewalk direction, one end of the drainage channel 3211 extends to the curb 4. A confluence groove 41 communicated with any one of the drainage grooves 3211 is integrally formed on the side wall of the kerbstone 4 close to the pavement layer 3, and a drainage port 42 communicated with the confluence groove 41 is integrally formed at the bottom of the kerbstone 4, so that rainwater flowing out of each drainage groove 3211 can be gathered together by using the confluence groove 41, and the drainage port 42 is communicated with a drainage pipeline or a sewer at the bottom of the ground to achieve the drainage effect. And the kerb 4 has dug one grooving 11 on the roadbed 1 of position, buries the bottom of kerb 4 in grooving 11 underground, can consolidate and spacing kerb 4, recycles kerb 4 and hinders the displacement of base brick 321 towards this side direction, makes base brick 321 difficult to separate each other to make the tiling brick 311 can not sink easily.
