Continuous beam swivel dismantling method
The invention discloses a continuous beam swivel dismantling method, which belongs to the technical field of bridge construction, and comprises the following steps: erecting a spherical hinge slideway bracket and a side span bracket, constructing a 0 # block bracket, and mounting a spherical hinge on the pier top; the cranes are installed on the two sides of the mid-span closure section, and the mid-span closure section is transversely cut and lowered to the ground; the side span cast-in-place section and the side span closure section are cut and removed to form a T-shaped structure, and the cut side span cast-in-place section and the cut side span closure section are lowered to the ground; the 0 # block permanent support is dismantled, and the spherical hinge is stressed; the two sides of the T-shaped structure are weighed and counterweighted; a rotation jack is installed to push the T-shaped structure to rotate; a pier beam temporary consolidation structure is installed, and locking of the 0 # block is completed; the T-shaped structure section is segmented and cut from the two ends to the middle, and is lowered to the ground to be dismantled and carried away; and the 0 # blocks are segmented and dismantled one by one, and dismantling of the cross-road bridge structure is completed.
本发明公开了一种连续梁转体拆除方法，属于桥梁施工技术领域，包括：搭设球铰滑道支架和边跨支架，0#块支架施工，并在墩顶安装球铰；中跨合龙段两侧安装吊机，横向切割中跨合龙段并下放至地面；切割拆除边跨现浇段和边跨合龙段形成‘T’构，并将切割下来的边跨现浇段和边跨合龙段下放至地面；拆除0#块永久支座，使球铰受力；‘T’构两侧进行称重并配重；安装转体千斤顶推动‘T’构进行转体；在安装墩梁临时固结结构，完成0#块的锁定；‘T’构段由两端向中间进行分段切割，并下放至地面拆除运走；逐块分割拆除0#块，完成跨道路桥梁结构的拆除。
