客土喷播在潭邵高速公路石质边坡防护中的应用

Study of spray seeding on outside soil of the rocky slope of Tan-Shao express highway

介绍了潭邵高速公路石质边坡客土喷播生物防护技术的适应情况、施工工艺及工程试验情况,指出了这一防护技术与传统的边坡防护相比较,具有机械化程度高、施工安全、稳定表层边坡、成本低等优点,同时对极陡边坡(1∶0.3～1∶0.75)采用客土与植本地草皮相结合的办法,达到了满意的效果,造价仅为喷混植草的70%,且生长快,绿化效果更好。

Spray seeding on outside soil of the rocky slope of Tan-Shao express highway is introduced, including adaptation, technical process and test of this biological protection technology. Compared with traditional slope protection, it has advantages such as high mechanization degree, safe construction, stable slope surface, low cost etc. At the same time, combining outside soil method with planting local sod yields satisfactory results, 70 percent cost of spray seeding mixture, with speed growth and better virescence effect.
