Ситуация:
End of January 2021, the metropolitan area of Santiago endured heavy rainfalls of more than 116 mm. A phenomenon that had not occurred since 1933. This, plus the scarce vegetation in the mountains and a zero isotherm above 3,500 meters, activated several streams and gullies.
In the commune of Lo Barnechea the water affected homes, streets, roads, and infrastructure and caused emergency works.
Описание:
The solution consists of seven dynamic barriers of the VX-type installed in the three streams affected mainly by the floods.
- Seca gully: 1 VX-80-H4 barrier 16 meters wide and 4 meters high
- Ñilhue gully: 1 VX-160-H6 barrier 13 meters wide and 6 meters high and 2 VX-140-H4 barriers 12 meters wide and 4 meters high
- Huallalolén gully: 3 VX-140-H4 barriers 18 meters wide and 4 meters high
The retention capacity of all seven ring net barriers is 6’900 m³.
