00:00Who would have thought riverbank road collapse repair works like this?
00:03First step, excavator clears all damaged guardrails and loose collapsed road debris completely.
00:07Then steel sheet piles driven in blocking river water out.
00:10Water blocked, formwork assembled, rebar skeleton laid, concrete poured directly
00:14reinforcing the entire collapse section. Once concrete sets, formwork removed,
00:19cutting machine trims all edges clean. Sand base layer spread, large crushed stone laid,
00:24road roller compacts repeatedly, hot asphalt paved and pressed flat, new and old road surfaces level
00:28together. Road now more resistant to erosion, more stable and durable. Next, rural main road collapse
00:34repair. Large scale sinkhole appears in the middle of the road. Workers excavate directly down to solid
00:39base, rebar mesh laid, concrete poured locking the entire foundation in one pour. Once fully cured,
00:45crushed stone spread, road roller compacts repeatedly, standard road construction completes the surface,
00:50entire two-way main road successfully restored and reopened. This approach won't fail for 10 years.
00:55Finally, a muddy pothole country laying beside a stream, even off-road vehicles slip easily.
01:00Construction team first installs formwork on the water side, pours concrete retaining wall
01:04stabilizing the road edge and blocking water erosion. Sand transported and filling all potholes,
01:08road roller compacts repeatedly building a solid base layer. Crushed stone laid and compacted again
01:13further increasing load capacity, standard road construction completes the surface,
01:16smooth comfortable country road is finished.
