Cable-stayed bridge dismantling construction method
The invention discloses a cable-stayed bridge demolition construction method, and relates to the technical field of bridge demolition. Comprising the steps that a main beam and a cable bent tower of a bridge are detected, and the cable bent tower comprises an upper tower column and a lower tower column; a temporary pier is arranged below the side span main beam connected with the bridge abutment; the main beam and the upper tower column are fixedly connected to increase the overall rigidity of the bridge, and the stability of the bridge in the dismantling process is improved; the cable-free area is firstly dismantled, and a first cable-stayed bridge structure and a second cable-stayed bridge structure which are independent and symmetrical are formed; when the first cable-stayed bridge structure is dismantled, the mid-span beam body is firstly dismantled, then the upper tower columns are dismantled, then the side-span beam bodies are dismantled, and finally the lower tower columns, the temporary piers and the bridge abutments are dismantled; when the second cable-stayed bridge structure is dismantled, similarly, the midspan beam body is dismantled firstly, then the upper tower column is dismantled, then the side span beam body is dismantled, and finally the lower tower column, the temporary pier and the bridge abutment are dismantled. The method is unique and novel, convenient and efficient in construction, low in cost and capable of meeting modern construction requirements.
本发明公开了一种斜拉桥拆除施工方法，涉及桥梁拆除技术领域；包括对桥梁的主梁及索塔进行检测，其索塔包括上塔柱和下塔柱；在与桥台相接的边跨主梁下设置临时墩；将主梁和上塔柱固结以增加桥梁整体刚度，提升桥梁拆除过程中的稳定性；先拆除无索区，形成独立且对称的第一斜拉桥结构和第二斜拉桥结构；拆除第一斜拉桥结构时，先拆除中跨梁体，再拆除上塔柱，然后拆除边跨梁体，最后拆除下塔柱、临时墩和桥台；拆除第二斜拉桥结构时，同样先拆除中跨梁体，再拆除上塔柱，然后拆除边跨梁体，最后拆除下塔柱、临时墩和桥台。本方法独特新颖，施工方便高效，成本低，符合现代化施工要求。
