Cast-in-place construction method for large-span diamond-shaped bent cap of high pier
According to the cast-in-place construction method for the large-span diamond-shaped bent cap of the high pier, cast-in-place construction of inclined legs and the bent cap is achieved through a two-part supporting system, in the first part, a combined supporting system is formed through 45a double-spliced I-shaped steel, a channel steel bracket and a slope bracket, and cast-in-place constructionof an inclined leg supporting bent cap structure is achieved; and in the second part, a fastener type steel pipe full framing is erected at the hollow structure on the tie beam which is poured and solidified, square timbers and formworks are laid, and cast-in-place construction of the cross beam is achieved. The construction method is a very simple, effective, safe, reliable, rapid and economicalconstruction scheme for viaducts and municipal bridges constructed under the complex conditions of high piers crossing rivers, valleys crossing, soft soil foundations crossing and the like. By the adoption of the construction technology, the defects that a traditional bracket is difficult to construct, long in construction period, high in cost, large in risk, multiple in potential safety hazard and the like are overcome.
本发明为一种高桥墩大跨度钻石造型盖梁现浇施工方法，采用两部分支撑体系实现斜腿、盖梁现浇施工，第一部分通过45a双拼工字钢、槽钢托架以及斜面托架形成组合支撑体系，实现了斜腿支撑盖梁结构的现浇施工；第二部分是在已浇筑固结的系梁上空心结构处搭设扣件式钢管满堂支架、铺设方木、模板，实现横梁现浇施工。本发明施工方法对于高墩跨河、跨山谷、跨软土地基等复杂条件下施工的高架桥、市政桥梁是一种非常简单、有效、安全、可靠、快速、经济的施工方案。采用本发明施工技术，避免了传统支托架施工难、工期长、成本高、风险大、安全隐患多等弊端。
