Sectional type quick mounting and dismounting construction method for front guide beam by incremental launching method
The invention relates to the technical field of bridge construction, in particular to an incremental launching method front guide beam sectional type rapid mounting and dismounting construction method which comprises the following steps: jacking a first section of steel beam and pushing the steel beam towards a tunnel, and when a first bridge section is jacked and pushed, constructing a second bridge section in the tunnel to enable the second bridge section to extend out of the tunnel; and when the first bridge section is close to the sectional type front guide beam and close to the part, extending out of the tunnel, of the second bridge section, the sectional type front guide beam is disassembled section by section, and after the sectional type front guide beam is disassembled, welding between the first bridge section and the second bridge section is completed. According to the incremental launching method front guide beam sectional type rapid mounting and dismounting construction method, the first bridge section and the second bridge section can be constructed synchronously, the overall construction efficiency is improved, and the butt joint difficulty of the first bridge section and the second bridge section is reduced; meanwhile, a crane can be arranged on the part, extending out of the tunnel, of the second bridge section, and the sectional type front guide beam is convenient to disassemble and transport; in addition, the sectional type front guide beam can reduce the hoisting and conveying difficulty and reduce the occupied space when the front guide beam is disassembled.
本发明涉及桥梁施工技术领域，尤其涉及一种顶推法前导梁分段式快速安拆施工方法，包括如下步骤：将首段钢梁顶起并朝向隧道推动，顶推第一桥段时，对隧道内的第二桥段进行施工，使得第二桥段伸出隧道设置；当第一桥段靠近分段式前导梁靠近第二桥段伸出隧道的部分时，逐段拆卸分段式前导梁，分段式前导梁均拆除后，将第一桥段与第二桥段之间焊接完成。本发明的顶推法前导梁分段式快速安拆施工方法，能够同步施工第一桥段和第二桥段，提升整体的施工效率，降低第一桥段与第二桥段对接时的难度；同时第二桥段伸出隧道的部分可以安置吊机，便于拆卸和运输分段式前导梁；此外分段式前导梁能够降低吊装与输送的难度，减少前导梁拆卸时所需占据的空间。
