Bridge capping beam construction cross-core rod dismantling method
The invention provides a bridge cover beam construction cross-core rod dismantling method which comprises the steps that before a cross-core rod hole is in place, a through inclined hole is formed in one end of a cross-core rod, and a hoisting hole is formed in the other end of the cross-core rod; a pulling rope is arranged in the inclined hole in a penetrating manner, and one end of the pulling rope is knotted and fixed at the end part of the core penetrating rod; a lifting rope is arranged in the lifting hole in a penetrating manner, and one end of the lifting rope is knotted and fixed at the end part of the core penetrating rod; when the hole of the cross-core rod is in place, one end of the cross-core rod and one end of the traction rope are plugged into the pier column preformed hole PVC pipe together; when the cross-core rod is disassembled, firstly, one end, close to the lifting rope, of the cross-core rod is sleeved with a flared pipe, an auxiliary rope is fixed to the flared pipe, and the other end of the auxiliary rope is tied to the top of the cover beam; reserving a certain length of the lifting rope, and tying the other end of the lifting rope on the top of the capping beam; an operator pulls the traction rope at the top of the cover beam, and the cross-core rod is slowly pulled out; after the cross-core rod is pulled out, the cross-core rod is lowered to the ground through the lifting rope. The method has the advantages of simple operation, safety, reliability, high efficiency and the like.
本发明提供的一种桥梁盖梁施工穿心棒拆除方法，包括穿心棒孔洞就位之前，在穿心棒的一端开设有贯穿的斜孔，另一端开设有吊装孔；在所述斜孔内穿设有牵引绳，且所述牵引绳的一端在穿心棒的端部打结固定；在所述吊装孔内穿设有吊绳，且所述吊绳的一端在穿心棒的端部打结固定；穿心棒孔洞就位时，将穿心棒和牵引绳的一端一起塞入墩柱预留孔PVC管内；穿心棒拆卸时，先在穿心棒靠近吊绳一端套设喇叭管，喇叭管上固定有辅助绳，且所述辅助绳的另一端系在盖梁顶；将吊绳预留一定长度，另一端也系在盖梁顶；作业人员在盖梁顶拉动牵引绳，缓慢将穿心棒拔出；穿心棒拔出后，利用吊绳将穿心棒下放至地面。本发明方法具有操作简便、安全可靠、效率高等优点。
