FIELD: construction.SUBSTANCE: onto an earth strip directly adjacent to embankment foot, with width of 2.5-3.0 meters, fertile soil is moved in one-two trips of a grader from a strip located at the distance of 4.0-7.0 meters from the slope foot, to produce a layer of 15-20 cm. Then earth is ploughed up with full layer turnover for depth of 50 cm. At the same time it is tilled, and fertile layer is moved to the depth of 20-50 cm, and layer of low-fertility soil reaches the surface, further preventing intense development of weed plants. Then, using a tree planter, low-growing or trailing creeping-rooted shrubs are planted into the prepared soil, and its roots, getting during planting into fertile soil, which is periodically wetted with precipitation flowing off the road bed, develop intensively and produce root shoots, which populate the entire embankment slop to its border.EFFECT: increased efficiency of motor road embankment slopes fixation due to soil strengthening with durable and strong branched roots of shrubs. |
