湖北英山养路段,几年来对水毁防治工作抓得早、抓得细、抓得狠、抓得好。因此,虽然公路修通不久(1958年修通),基础薄弱,但从未造成严重水毁。每年的水毁防治工作,除抓清沟排水、整修桥涵外,还着重地抓稳定路基。稳定路基的主要方法就是抓草皮护坡,草皮护肩(路肩):一、草皮护坡1.满植草皮护坡:将它处的草皮,移植于填方边坡上,整个边坡面积栽上一层,这种方法适用于大填方、新路基、及草皮来源较多的地段。其效果好,但不够经济。如芭茅较多地区,满植芭茅也很好。2.花植草皮护坡:将草皮栽植成鱼鳞形、方格形……等,适用于小填方或挖方上坡,对缺草地方这种方法更现实,它费工少非常经济。另一种花植办法是:对特别缺草地方可切挖较宽 Yingshan Road, Hubei section of the past few years, prevention and control of water damage caught early, carefully, grasping ruthless, well grasp. Therefore, although the road was repaired shortly after the completion of the road in 1958, the foundation was weak but no serious water damage was caused. Every year, water damage prevention and control work, in addition to grasping ditch drainage, renovation of bridges and culverts, but also focus on the stability of subgrade. The main way to stabilize the subgrade is to take the grass turf and the turf shoulder (shoulder): First, the turf slope protection 1. Full turf slope protection: the turf it is transplanted to the fill side slope, the entire slope area planted with a layer , This method is suitable for large fill, new roadbed, and turf source more lots. The effect is good, but not economical enough. As Batik more areas, full of plantain is also very good. 2. Flower grass sod protection: the turf planted into a fish-shaped, square-shaped ... ..., apply to a small fill or dig uphill, the lack of grass where this method is more realistic, it is less laborious and very economical. Another way to plant flowers is: a special lack of grass can cut a wide area
