Hoisting process of extra-large asymmetric steel structure bridge
The invention relates to a hoisting process of an extra-large asymmetric steel structure bridge. The hoisting process comprises the following specific steps that S1, a three-dimensional space solid model of the asymmetric steel structure bridge is established; S2, cross beams are horizontally and outwards laid at the same side ends of two bridge piers; S3, a gantry crane enters into a field and lifts the asymmetric steel structure bridge, one end, away from an electric hoist, of a rope is fixed to a corresponding lifting lug, and the asymmetric steel structure bridge is lifted so that the height of the asymmetric steel structure bridge can be consistent with the height of cross beams of the two bridge piers; S4, the two ends of the asymmetric steel structure bridge are provided with sleeve bodies of a U-shaped structure in a sleeving mode; and S5, the electric hoist is started, and the lower portion of the asymmetric steel structure bridge is placed on the two bridge piers. The hoisting process has the advantages that a gravity center of the asymmetric steel structure bridge and positions of the lifting lugs are accurately positioned, so that hoisting balance is guaranteed, and meanwhile, two sides of the bridge are connected with a sliding device in the hoisting process and then slide on the cross beams to further guarantee the hoisting balance.
本发明涉及一种特大不对称钢结构桥梁的吊装工艺，具体步骤包括：S1、建立不对称钢结构桥梁的三维空间实体模型；S2、在两桥墩的同侧端水平向外均铺设有横梁；S3、龙门式起重机进场并起吊不对称钢结构桥梁，并将绳索远离电动葫芦的一端与对应的吊耳固定，并起吊不对称钢结构桥梁使不对称钢结构桥梁与两桥墩的横梁的高度一致；S4、在不对称钢结构桥梁的两端套上U形状结构的套体；S5、启动电动葫芦，将不对称钢结构桥梁下放置两桥墩上。本发明具有如下优点：精确定位不对称钢结构桥梁的重心以及吊耳的位置，从而保证吊装平衡，同时吊装过程中将桥梁两侧与滑动装置连接后在横梁上滑动来进一步保证吊装的平衡性。
