Method for hoisting newly-added pile foundation reinforcement cage in narrow space under bridge reinforcing bridge
The invention discloses a method for hoisting a newly-added pile foundation reinforcement cage in a narrow space below a bridge reinforced bridge, which comprises the following steps of: A, drilling two holes on an original bridge floor, installing an upper carrying pole beam on the bridge floor between the holes, arranging an upper carrying pole beam lifting lug on the upper carrying pole beam, and connecting a first hoisting steel wire rope with a hoisting device after penetrating through the upper carrying pole beam lifting lug; B, arranging a lower carrying pole beam below the original bridge, arranging two lower carrying pole beam lifting lugs on the lower carrying pole beam, and installing a lifting hook in the middle of the bottom of the lower carrying pole beam; C, making a steel wire rope penetrate through the lower carrying pole beam lifting lug to be connected with the upper carrying pole beam; and D, lifting the reinforcement cage by the lifting hook through the steel wirerope. According to the method, hoisting and mounting construction of the reinforcement cage can be completed in a narrow space under the bridge. The method has the characteristics of obviously shortening the construction period, reducing the construction cost and improving the construction safety and quality.
本发明公开了一种桥梁加固桥下狭小空间新增桩基钢筋笼吊装的方法，包括有以下步骤：A.在原桥面上钻两个孔洞，孔洞之间的桥面安装上扁担梁，上扁担梁上设上扁担梁吊耳，第一起吊钢丝绳穿过上扁担梁吊耳与起吊装置连接；B.原桥梁下方设下扁担梁，下扁担梁上设2个下扁担梁吊耳，下扁担梁底部正中间安装吊钩；C.钢丝绳穿过下扁担梁吊耳与上扁担梁连接；D.吊钩通过钢丝绳对钢筋笼实施吊装作业。该方法可在桥下狭小空间内对钢筋笼完成吊、安装施工。具有明显的节约工期、降低施工成本和提高施工安全和质量的特点。
