Meanwhile, protective measures should be taken on both sides of the culvert to reduce the erosion of steel corrugated culvert port and bottom cushion layer, so as to improve the service life and anti-corrosion ability of steel corrugated culvert pipe.
3. There must be no cracks in the concrete poured by the culvert end; otherwise, water will break the hole and the whole bridge surface will collapse over time.
