摘要
The present invention relates to a revegeration method using long fiber in the special geologic region generating acid drainage. In the present invention, penetration of acid drainage and acidification of an artificial soil generated from acid drainage are suppressed by forming a multiple layered membrane in the slope in which vegetation quality securing and vegetation environment improving are hard due to acid drainage generated in the special geologic region like mudstone, and by spraying a revegeration soil mixed with neutralization treatment additives, the long fiber and the seed thereby inducing an improvement of scenery and ecological function through growing the plant in the slope of the special geologic region. The present invention to accomplish the previously mentioned objective comprises the following steps: a step of spraying dolomitic limestone forming a dolomitic limestone layer by spraying a dolomitic limestone after diluting in the water on the slope generating acid drainage; a step of installing curing bag preventing an outflow of acid drainage by installing a curing bag on the dolomitic limestone layer; a step of spraying calcium phosphate neutralizing acid drainage, and block the outflow of acid drainage to upper side of the curing bag by forming calcium phosphate coating layer on the curing bag through spraying calcium phosphate after diluting in the water on the curing bag; a step of installing fixing net installing a fixing net on the calcium phosphate coating layer; a step of spraying vegetation base material forming a vegetation base layer by spraying a vegetation base material, seed and long fiber on the calcium phosphate coating layer to reclaim the fixing net.
