Suspension bridge front anchor chamber approaching construction method
The invention relates to a suspension bridge front anchor chamber approaching construction method which comprises the following steps: step 1, digging a foundation pit of a front anchor chamber at a preset position, building anchors, enabling two ends of a plurality of steel cables to penetrate through a gantry of a suspension bridge and then respectively hoisting the steel cables to front anchor surfaces of the anchors at two ends of the suspension bridge; secondly, the two ends of a plurality of steel cables penetrate through front anchor face anchor bearing plates of anchors at the two ends of the suspension bridge respectively and are anchored to the anchors; thirdly, the multiple steel cables are folded to form a main cable of the suspension bridge; fourthly, scaffolds are erected on the scattered steel cables at the ends of the main cables, transverse supporting beams are erected at the top of the foundation pit where the steel cables are dense, and the scaffolds continue to be erected on the basis of the supporting beams; fifthly, a top cover formwork is erected on the top of the scaffold; and sixthly, concrete is poured into the top cover formwork to form a top cover to seal the foundation pit, and a front anchor chamber is formed. The construction method has the effects that the scaffold is conveniently erected above the dense main cable position, so that the top cover is poured above the front anchor chamber, and the safety of the top cover template structure is improved.
本申请涉及一种悬索桥前锚室贴近法施工方法，其施工方法包括：步骤一：在预定位置挖出前锚室的基坑并建造锚锭，将若干根钢索两端穿过悬索桥的门架后分别吊运至悬索桥两端锚锭的前锚面处；步骤二：将若干根钢索的两个端部分别穿过悬索桥两端锚锭的前锚面锚垫板并锚固于锚锭；步骤三：将若干根钢索合拢形成悬索桥的主缆；步骤四：在主缆端部散开的钢索上架设脚手架，在钢索密集处的基坑顶部搭设横向的支撑梁，以支撑梁为基础继续搭设脚手架；步骤五：在脚手架顶部架设顶盖模板；步骤六：在顶盖模板内浇筑混凝土形成顶盖封闭基坑形成前锚室。本申请具有便于在主缆密集处上方架设脚手架从而在前锚室上方浇筑顶盖，提升顶盖模板结构安全性的效果。
