Construction method for dismantling continuous beam old bridge on navigation channel of inland river
The invention belongs to the field of bridge demolition construction, and particularly discloses a continuous beam old bridge demolition construction method on an inland river navigation channel, and the demolition construction method specifically comprises the following steps: carrying out segment division on a continuous beam old bridge to be demolited, and dividing the continuous beam old bridge into a bridge deck system, a midspan middle segment, a midspan side segment and a side span segment; dismantling a bridge deck system in a hoisting mode of a truck crane; the midspan middle section is dismantled in a floating crane hoisting mode; the side span sections are temporarily supported, and then the middle span side sections on the two sides are dismantled in a floating crane hoisting mode; and finally, the side span section is directly crushed and dismantled. According to the method, the continuous beam old bridge is subjected to segment division, and the continuous beam old bridge is dismantled in different modes according to the division result, so that the time of single-time navigation closure can be effectively shortened, the influence on the operation of a navigation channel is reduced, and the risk of collision of passing ships due to incomplete salvage is avoided.
本申请属于桥梁拆除施工领域，具体公开了一种内河通航航道上连续梁老桥拆除施工方法，该拆除施工方法具体为：将待拆除的连续梁老桥进行节段划分，分成桥面系、中跨中段、中跨边段和边跨段；采用汽车吊吊装的方式进行桥面系的拆除；采用浮吊吊装的方式进行中跨中段拆除；对边跨段进行临时支撑，然后采用浮吊吊装的方式对两侧的中跨边段进行拆除；最后直接对边跨段进行破碎拆除。本申请提出将连续梁老桥进行节段划分，并根据划分结果采用不同的方式进行拆除，能够有效降低单次封航的时间，进而减小对通航航道运行的影响，避免因打捞不彻底导致出现过往船只碰撞的风险。
