1995年初铁道部设计鉴定中心批准中国铁路工程总公司和铁道部第四勘测计院共同在京九线阜九段选点开展OH—COAT技术科学试验。课题组利用OH液稀释喷洒于撒有草籽的路基坡面上,防止坡面和草籽在雨季为雨水冲蚀,保护草籽发芽生长,形成良好植被防护。该组广泛搜集、吸收国内外有关技术资料、试验确定了OH液和草籽的各项施工参数、制定了施工工艺,经在京九及麻武联络线上分别对采用黄粘土及风化红砂岩填筑的两处路堤试验,其中最大的一天暴雨量为232mm,边坡状态完好,与相邻路段用干砌片石骨架内铺草皮防护护坡,冲刷坍塌、损失惨重情况相比,有显著的成效。
At the beginning of 1995, the Ministry of Railways Design and Approval Center approved that China Railway Engineering Corporation and Ministry of Railways IV Survey and Survey Institute jointly carry out OH-COAT technical scientific experiment at the election site of Fujiu of Beijing-Kowloon Line. The research team used OH liquid to dilute and spray on the slopes of grass-covered roadbed to prevent rainwater erosion on the slope and grass seeds in the rainy season and protect the germination and growth of the grass seeds to form a good vegetation protection. The group extensively collected and absorbed relevant technical data both at home and abroad, experimentally determined various construction parameters of OH liquid and grass seeds, and formulated construction technology. By using the yellow clay and the weathered red sandstone Two embankment tests, including the largest one day rainfall of 232mm, the state of the slope intact, with the adjacent sections of dry masonry skeletons within the protection of slope protection, erosion collapse, the case of heavy losses compared to the significant results.
