DETAILED DESCRIPTION
[0017] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.
[0018] Please refer to Figs. 1-2The utility model provides a sidewalk interlocking block, including body 1 and support structure, the support structure sets up in the four around of body 1, the body 1 is provided with a plurality of drainage pipeline 2, and the top of body 1 is provided with the water collecting tank 3, the bottom of water collecting tank 3 is connected with the top of drainage pipeline 2, and the bottom of body 1 is equipped with a plurality of positioning cone 4, and drainage pipeline 2 penetrates body 1 and positioning cone 4, the bottom of drainage pipeline 2 is set up in the bottom of positioning cone 4, the bottom of positioning cone 4 is provided with a plurality of drainage port 5 along the axial annular array, one end of drainage port 5 is connected with the bottom of drainage pipeline 2, and one end is connected with the outside, and drainage port 5 is provided along the axial radial of positioning cone 4.
[0019] Positioning cone 4 can improve the stability of interlocking block in soil, and positioning cone 4 can provide a certain effect of stabilizing soil, so as to avoid the subsidence of sand layer.
[0020] The support structure includes the vertical setting partition plate 6, the partition plate 6 is arranged on the edge of the body 1, and the partition plate 6 is arranged between each interlocking block body, the top of the partition plate 6 is provided with a water baffle 7, the water baffle 7 is inverted triangle, the edge top of the body 1 is provided with a sputtering groove 8, the inclination direction of the sputtering groove 8 is same with the inclination direction of the edge of the adjacent water baffle 7, the bottom of the partition plate 6 is provided with a support strip 9, the support strip 9 is arranged between the bottom of two interlocking block bodies, and is used for supporting and limiting the body 1 in the soil. When the accumulated water flows in the gap between the body 1 and the body 1, due to the integrated structure of the partition plate 6, the water baffle 7 and the support strip 9, the sand soil loss caused by the filling reduction of the partition plate 6 cannot flow with the flowing water, even if the sandstone loses, the lower end of the water baffle 7 is smaller than the upper end, the narrow space structure is formed between the water baffle 7 and the sputtering groove 8, when the accumulated water flows through the space, due to the limitation of the water baffle 7, the direction of the accumulated water spray can only go out at a small inclination angle, so when the pedestrian treads the body 1, the accumulated water is prevented from splashing vertically upward to the shoes of the people, thereby avoiding the inconvenience brought to the pedestrians.
[0021] The side surface of the body 1 is provided with a plurality of water retaining structures, the water retaining structure is provided with a plurality of concave surfaces 10 communicated in sequence from top to bottom in the vertical direction, the concave surface 10 includes a straight surface adsorption surface 11 and a curved surface adsorption surface 12, the straight surface adsorption surface 11 extends obliquely upward to the inside of the body 1, the top of the straight surface adsorption surface 11 is fixedly connected with the bottom of the curved surface adsorption surface 12, an upward channel is arranged between the curved surface adsorption surface 12 and the bottom of the next straight surface adsorption surface 11, and the curved surface adsorption surface 12 and the next straight surface adsorption surface 11 form a convex surface 13.
[0022] When the pedestrian walks on the body 1, the foot has a downward pressure on the body 1, and the accumulated water under the body 1 is extruded, and the extruded accumulated water can only overflow from the edge of the body 1. The pressure of the foot on the surface of the body 1 is greatly affected by the speed of the foot, and the faster the speed, the greater the extrusion force of the accumulated water under the body 1, and vice versa. When the extrusion force of the accumulated water is large, the speed of the accumulated water overflowing from the edge of the body 1 is faster. The gap between the two adjacent bodies 1 is very limited, and when a certain fluid flows through a limited cross-sectional space, the greater the extrusion force, the faster the fluid flows. Because the edge of the body 1 is provided with the water retaining structure of the concave surface 10 and the convex surface 13, first of all, according to the characteristics of the fluid, that is, the difference in the size of the surface tension of the fluid and the adhesion between the contact surfaces, the surface tension of the fluid has a force to minimize its surface area, and the adhesion between the fluid and the contact surface prevents the area from shrinking. When the accumulated water flows through the concave surface 10 and the convex surface 13, it will show a corresponding concave liquid surface or convex liquid surface. The accumulated water tends to be close to the contact surface when flowing, and the accumulated water flows along the surface area of the lower convex surface 5 to the concave surface 10. Since the concave surface 10 is inwardly recessed, if the accumulated water continues to flow upward, it will avoid colliding with the inner wall of the concave surface 10. The collision between the accumulated water and the inner wall of the concave surface 10 will affect its kinetic energy, which will consume the kinetic energy, and the kinetic energy of the accumulated water flowing upward will decrease, and the speed of the accumulated water flowing through the convex surface 13 will be greatly reduced. The inwardly recessed concave surface 10 can block part of the accumulated water that cannot pass through the concave surface 10. The accumulated water flowing through the straight surface adsorption surface 11 is attracted by the adsorption force of the fluid to make the accumulated water closer to the straight surface adsorption surface 11. The accumulated water that flows through the curved surface adsorption surface 12 after reaching the straight surface adsorption surface 11 will hit the accumulated water flowing upward, further blocking the accumulated water flowing upward, and further reducing the kinetic energy of the accumulated water flowing upward.
[0023] The accumulated water will eventually be sprayed out of the arc-shaped splash groove. The convex surface 13 is arc-shaped and protruding. According to the characteristics of the fluid flowing through the surface of the object and the trajectory after being sprayed, the angle at which the accumulated water is sprayed out of the upper end of the convex surface 13 must be an oblique angle. If the position of the pedestrian's foot is close to the edge of the body 1, and the shoe has a certain height and thickness, and the edge of the shoe itself has a waterproof design, the obliquely sprayed water stains will directly act on the edge of the side of the shoe sole, and the water stains cannot be directly sprayed to the upper to cause it to be wet.
[0024] If the pedestrian's foot is far from the edge of the body 1, the water stains sprayed at a parabolic angle will have a longer path and a lower height due to their initial speed and angle. Assuming the initial speed is the same as that of the traditional paving structure, the inclined spray has a longer path but a lower height. The speed of the structure is smaller due to the convex surface 5, concave surface 10, and convex surface 13 structure, which consumes a certain amount of kinetic energy, so the effect on the pedestrian is very limited.
[0025] As an example, the drain 5 is inclined upward to prevent soil expansion and blockage of the horizontal pipeline. The top of the drain 5 is provided with a mud angle 14 to further prevent soil from blocking the drain 5.
