Highway engineering cement soil roadbed cushion layer and construction technology thereof
The invention discloses a highway engineering cement soil subgrade cushion layer which comprises cement, soil, water and stones, and the mass ratio of the cement to the soil is 6%. P.O42.5 general-purpose Portland cement is selected as the cement, and the alkali content in the cement is less than or equal to 0.60%; the selected soil plasticity index is 10-26, and the water content is 15-25%. The epoxy resin protective layer, the reinforcing mesh layer and the spring steel are arranged, and the epoxy resin protective layer is provided with a high polymer of a three-way net structure and has excellent insulating property, mechanical property, chemical stability and the like; the reinforcing mesh layer is a mesh formed by arranging longitudinal reinforcing steel bars and transverse reinforcing steel bars at certain intervals, forming right angles with each other and welding all cross points together, so that the crack resistance of concrete is enhanced, the engineering quality of the reinforcing steel bars is remarkably improved, and spring steel has excellent metallurgical quality, good surface quality and accurate appearance and size; the problems that combination among cement, sand and stone can be enhanced, the using effect is good, and the road quality can be improved are solved.
本发明公开了一种公路工程水泥土路基垫层，包括水泥、土、水和石，其中，水泥和土的质量比为6％；水泥选择采用P.O42.5通用硅酸盐水泥，水泥中的碱含量≤0.60％；土质选择塑性指数10‑26、含水率15％‑25％。通过设置环氧树脂防护层、钢筋网片层、弹簧钢，环氧树脂防护层具有三向网状结构的高聚物，其具有优良的绝缘性能、力学性能及化学稳定性等，钢筋网片层是纵向钢筋和横向钢筋分别以一定的间距排列且互成直角、全部交叉点均焊接在一起的网片，增强混凝土抗裂能力，显著提高钢筋工程质量，弹簧钢具有优良的冶金质量、良好的表面质量、精确的外形和尺寸，解决了能够增强水泥、沙子、石头之间的结合，使用效果好，可以提高公路质量的问题。
