- W2354263694 abstract "A bridge to be dismantled is located over river.It is a reinforced concrete double-curvature arch bridge,with 255 meters in length and 16 meters in width.It has 8 spans over the river with 30 meters per span,and 1 span over the riverbank.The bridge needs demolition and reconstruction due to the bridge aging and urban development,but both the bridge piers as well as the heat pipe which is 500 millimeters in diameter and 1.5 meters away from the bridge need to be preserved.The explosive demolition method is applied after the failure of mechanical removal method.According to force feature of the bridge,the drilling holes are designed at the bottom of the arch rib beam to break the bridge body.At the same time,the inter-connected reinforced concrete structure and the structure on pier top are cut by blasting.Bridge deck is an integral reinforced concrete structure,so the piers need to be cut off artificially firstly.The preventive method of fly-rock controlling is effectively by hanging out straw-filled sacks and bamboo sheet,or placing sand bags on surface." @default.
