Novel pavement deceleration strip for municipal engineering
The invention discloses a novel road surface speed bump for municipal engineering. The novel road surface speed bump comprises a rubber protection layer, a polymer air bag and a non-Newtonian fluid speed reduction layer, the rubber protection layer wraps the outer surface of the non-Newtonian fluid deceleration layer, and the rubber protection layer is filled with the macromolecule air bag. The radial section of the deceleration strip is in an arc shape, the radius of the arc shape is r, the vertical distance between the highest point of the arc shape and the bottom edge is d1, 0.2 r is equal to d1-0.3, and d1 is larger than or equal to 1 cm and smaller than or equal to 1.5 cm. The thickness of the rubber protection layer is d2, d1 = k * d2, and k is larger than or equal to 3 and smaller than or equal to 4. The polymer air bag is made of foaming polyurethane. The non-Newtonian fluid deceleration layer is obtained by adding polyethylene glycol 200 into nano silicon dioxide to obtain a shear thickening material and then mixing the shear thickening material with thickening xanthan gum and lamellar filler. The compressive strength and the tensile strength of the deceleration strip can be effectively improved, the non-Newtonian fluid deceleration layer can be promoted to be rapidly recovered after deformation, and deceleration and damping are effectively conducted on follow-up vehicles.
本发明公开了一种新型市政工程用路面减速带，包括：橡胶保护层、高分子气囊及非牛顿流体减速层；橡胶保护层包覆在非牛顿流体减速层外表面，高分子气囊填充在橡胶保护层内；所述减速带的径向截面为弧形，弧形半径为r，弧形最高点与底边的垂直距离为d1，则0.2r＝d1‑0.3，1cm≤d1≤1.5cm。橡胶保护层厚度为d2，d1＝k×d2，3≤k≤4。高分子气囊采用发泡聚氨酯制成。非牛顿流体减速层为采用纳米二氧化硅加入聚乙二醇200得到剪切增稠材料，再将剪切增稠材料与增稠黄原胶、片层填料混合得到。本发明可有效提高减速带抗压强度与抗拉强度，还可促使非牛顿流体减速层在变形后快速复原，有效对后续车辆进行减速减震。
