1: Straight-shaped raised bricks are used to pave straight roads. The straight-shaped protrusions point to the direction of the blind road, that is, walk along the straight-shaped protrusions when walking. Each strip is 5mm above the ground, and the width should be 0.3-0.6m, which can make the blind stick and the sole of the foot feel, and is convenient to guide the visually impaired to walk in a straight line safely.
2: Point-shaped raised bricks are used for laying corners. It is in the shape of dots, each dot is 5mm above the ground, and the width should be 0.3-0.6m, which can make the blind stick and the sole of the foot feel, so as to inform the visually disabled person that the space environment of the front route will change.
Blind material
Precast concrete blind road bricks; rubber and plastic blind road slabs; other materials (stainless steel, PVC, etc.) blind road profiles.
