Abstract: To solve the problem of culvert’s bottom plate abrasion in Toutun river reservoir, reinforcement with an average thickness of 10cm was applied at places where the washout area reached 7.5m² on the bottom plate. According to the features of water and sediment in the culvert and the previous measures and experiences, GHJ planting-bar anchorage glue of high strength was used for the anchorage of rebars of 16mm diameter. Through the bonded anchorage, single-layer reinforcement mesh with vertical and horizontal spacing (20cm× 20cm) between rebars of 12mm diameter was integrated with the basal layer as a whole, and then BZK-G grouting material was used for the grouting reinforcement. Two years of practice proved that this technique has good effect on the anti-abrasion of culvert bottom.
