Construction method of six-span continuous mixed beam bridge
The invention relates to the technical field of beam bridge construction, and discloses a construction method of a six-span continuous mixed beam bridge, which comprises the following steps of: 1, simultaneously constructing five bridge piers positioned at a middle section, and constructing a concrete beam body on the bridge piers; secondly, a temporary steel supporting platform is erected in water, and the large-section steel beams are assembled on the steel supporting platform; thirdly, the spliced large-section steel beams are sequentially installed on the concrete beam body from the two ends to the middle through a deck crane; and fourthly, after the large-section steel beam is installed, the deck crane is dismantled, and construction of a bridge accessory structure is conducted. The problem that in the prior art, construction of the six-span continuous mixed beam bridge needs to solve the overall construction method and the construction sequence of the concrete beams and the steel beams in the mixed beams is solved, the construction efficiency of the mixed beam bridge is improved, the construction risk is reduced, and the construction cost is reduced.
本发明涉及梁桥施工技术领域,公开了一种六跨连续混合梁桥的施工方法,包括:步骤一、同时施工位于中间段的五个桥墩,在所述桥墩上施工混凝土梁体;步骤二、在水中搭设临时钢支撑平台,在所述钢支撑平台上对大节段钢梁进行拼装;步骤三、通过桥面吊机对拼装后的所述大节段钢梁按从两端至中间的顺序依次安装在所述混凝土梁体上;步骤四、待所述大节段钢梁安装完成后,拆除所述桥面吊机,进行桥梁附属结构的施工。本发明解决了现有技术中六跨连续混合梁桥的施工需要解决混合梁中混凝土梁和钢梁的总体施工方法和施工顺序问题,提高混合梁桥的施工效率、降低施工风险、减少施工成本。
