Under conditions of a complex mountain relief the pioneer method of damming a river channel with one-sided narrowing of the gap is the best and most economical.
|
| 2. |
Closing of the gap on small and medium rivers by placing preliminarily stockpiled soil by powerful bulldozers or in combination with transporting of the soil by heavy-duty dump trucks makes it possible to increase the rate of filling by 2–5 times compared with the usual methods.
|
| 3. |
The high rate of filling (1000–1200 m3/h and more) of the layerwise fractionated soil and correct technology of closing the gap markedly reduce its erosion and evacuation by the flow.
