Dismantling method for bridge close to existing expressway and over-crossing navigation channel
The invention discloses a demolition method for a bridge close to an existing expressway and crossing a navigation channel. The demolition method for the bridge close to the existing expressway and spanning the navigation channel comprises a demolition method for the bridge spanning the highway and a demolition method for the bridge spanning the navigation channel, and the demolition method for the bridge spanning the navigation channel comprises preparation before construction and bridge demolition. Bridge dismantling comprises dismantling of a first bridge floor accessory structure, dismantling of a first T-beam, dismantling of a first lower structure and dismantling of a first connecting beam and a pile foundation, and dismantling of the first T-beam is conducted, specifically, a floating crane ship and a truck crane are adopted for combined operation, and the cut cross-channel T-beam is hoisted to a bridge floor which is not dismantled through a reverse method; and then transporting to a temporary crushing site in sections for crushing. According to the bridge demolition method, the floating crane ship and the truck crane are combined to hoist the T-shaped beam, the specification of the floating crane ship can be correspondingly selected according to the size of the water surface construction area beside the channel-crossing bridge, bridge demolition under different construction conditions can be met, and limitation is small.
本发明公开了一种临近既有高速公路及上跨通航航道的桥梁拆除方法。该临近既有高速公路及上跨通航航道的桥梁拆除方法包括跨公路的桥梁拆除方法和上跨通航航道的桥梁拆除方法，其中，上跨通航航道的桥梁拆除方法包括：施工前准备和桥梁拆除，桥梁拆除包括第一桥面附属结构物拆除、第一T梁拆除、第一下部结构拆除和第一连系梁及桩基拆除，第一T梁拆除：采用浮吊船和汽车吊联合作业，采用倒退法将切割后的跨航道T梁吊运至未拆除的桥面，然后再分段运输至临时破碎场地进行破碎。本发明提供的桥梁拆除方法采用浮吊船和汽车吊联合吊运T梁，可根据跨航道桥梁旁水面施工区域的大小对浮吊船的规格相应选择，可满足不同施工条件的桥梁拆除，局限性小。
