Embodiment Construction
[0016] Control attached figure 1 , the ecological restoration method of the concrete revetment slope, a rectangular sand-free concrete sump 4 is arranged on the side of the road at the junction of the road and the bank slope, and a gravel cushion 5 with a diameter of Φ20-50 is laid on the bottom of the groove. Permeable sand-free concrete drainage ditches 2 perpendicular to the sump 4 are arranged at regular intervals on the slope of the concrete revetment 1, and both sides of the drainage ditch 2 are formed of permeable sand-free concrete ridges 9. An impermeable sand-free concrete overflow ridge 6 is set between the rectangular sand-free concrete sump 4 and the permeable sand-free drainage ditch 2, and the sump 4 and the drainage ditch 2 are filled with Φ100-200 gravel. During construction, roughen the slope of the concrete revetment 1, and build a small groove; arrange a geocell 11 on the roughened slope, and lay an 80mm thick slope cell sand and gravel cushion 12 in the ge...
