The four corners of the first section 91 are provided with a third slot 93 and a third fixing ring 94. The first section 91 is also provided with a snap-fit ​​for engaging with aluminum sheets. The last section 92 is provided with a fourth slot 95 and a fourth fixing ring 96. No other layers are laid on the top and bottom of the last section 92. In this way, the customized paving can form a buffer ramp, which is suitable for use at the beginning and end of the tactile paving.

[0040] Vacuum screws 7 are installed on the first slot 63, the second slot 81, the third slot 93, and the fourth slot 95. The first fixing ring 64 and the third fixing ring 94 are connected to the extension part 8 by the vacuum screws 7, respectively. The eight holes on the first section 91 are connected to the ground by vacuum screws. The extension part 8 ensures that the side of the tactile paving forms a slope with the ground, making the connection between the tactile paving and the ground more harmonious and aesthetically pleasing. The vacuum screw 7 includes a top cap 71, a first support rod 72, a second support rod 73, and a base 74. The top of the top cap 71 is flat. The inner wall of the top cap 71 is a magnet 75, and the outer surface of the top cap 71 is made of hard rubber. The first support rod 72 is fixed to the top of the second support rod 73. The first support rod 72 is made of metal, and the second support rod 73 is made of hard rubber. The bottom of the base 74 is provided with a suction cup 76.

One side of the four equilateral triangular pieces is connected to each other to form a square, and the remaining sides point to the axial direction of the circular base plate.

[0041] In this embodiment, two steel pipes 42 are provided on the bottom layer 4; the bottom layer 4, the middle layer 5, and the top layer 6 are provided with a first buckle 46 and a second buckle 47 that cooperate with each other at both ends. The first buckle 46 and the second buckle 47 are provided on both sides of the end, with the first buckle 46 on the outside and the second buckle 47 on the inside, so that a seamless connection can be formed when connecting. The first layer 1, the second layer 2, and the third layer 3 are all connected by the cooperation of the first buckle 46 and the second buckle 47.

[0042] In this embodiment, the inner diameter of the pipe 41 is matched with the outer diameter of the steel pipe 42. Preferably, the inner diameter of the pipe 41 is 0-1 mm larger than the outer diameter of the steel pipe 42.

[0043] In this embodiment, the protrusion 61 is a circular protrusion or a strip-shaped protrusion.

[0044] In this embodiment, the height of the opening 44 on the side closer to the pipe 41 is less than the height on the other side.

[0045] In this embodiment, the first support rod 72 is made of iron or steel. During installation, the first support rod 72 is installed inside the top cap 71, and the magnet 75 attracts the first support rod 72. The second support rod 73 is installed inside the base 74. An anti-slip device 77 is installed on the second support rod 73. The anti-slip device is installed between the bottom layer and the vacuum screw vacuum cover, which allows the entire suspended tactile paving to be suspended in the air, allowing each panel to be grounded by the vacuum screw. This can maximize the conversion of the weight of the person passing by into the pressure of the vacuum cover to fix it more firmly to the ground.

[0046] In this embodiment, the first paving 1, the second paving 2, and the third paving 3 are independent of each other and have a width and length of 300*600mm or 400*800mm. The size of the tactile paving bricks on the market is usually 300*300mm or 400*400mm. The length of the bricks in this application is twice that of ordinary tactile paving bricks, which makes them more convenient and faster. The suspended tactile paving is composed of several first paving 1, second paving 2, third paving 3, extension part 8, and customized paving.

[0047] In this embodiment, the outer surfaces of the first layer 1, the second layer 2, the third layer 3, the extension section 8, and the custom layer are all covered with hard rubber, and different blocks are painted with different colors.

[0048] The present invention is a suspended tactile paving system. During construction, it is constructed by splicing together several first paving 1, second paving 2 and third paving 3 according to the road surface conditions. Custom paving can be used at the beginning and end of the road to form a buffer zone with the bottom surface, making it convenient for blind people to step into and out of the tactile paving.

[0049] The outer surfaces of the slides and other components involved in this invention are all covered with rubber, which is non-slip, wear-resistant, sound-absorbing, moisture-proof, flame-retardant, elastic, and not easily corroded. Walking on them is also comfortable. The structure of this invention mostly adopts a hollow design, making it easy to clean. The bottom layer has a steel structure, providing good fault tolerance and being suitable for uneven surfaces, creating a gap between the surface and the bottom layer for greater walking comfort. The tactile paving of this invention uses a splicing design, making construction and installation convenient. Because of the mostly hollow design, it has good drainage performance, allowing for rapid drainage in rainy weather and keeping the surface dry. Each block is painted with a different color, serving as a warning to bystanders and providing good anti-interference performance. This invention uses vacuum screws to fix the tactile paving to the ground. The bottom of the vacuum screw is a suction cup; stepping on the tactile paving strengthens the vacuum screw, without damaging the ground. It can be widely used in existing pavements such as those in shopping malls and parks, eliminating the need for reconstructing the pavement.
