Construction process for special-shaped concrete tower column of asymmetric cable-stayed bridge
The invention discloses a construction process for a special-shaped concrete tower column of an asymmetric cable-stayed bridge, the construction process comprises the following steps: step 1, tower base construction: a main tower base is in the form of a prismatic table which is inwards inclined by 45 degrees, a support template pouring concrete construction process is adopted for construction, and a customized steel template with the thickness of 8mm is adopted as a tower base template; the construction process has the beneficial effects that the processes of pouring, climbing, curing and the like in each construction stage of the special-shaped concrete tower column of the asymmetric cable-stayed bridge are strictly controlled before and after construction, so that the construction precision of the special-shaped concrete tower column of the asymmetric cable-stayed bridge is improved; the bending moment phenomenon caused by overlarge self weight or construction load capacity of the tower bridge is effectively avoided, the tower column root is prevented from being fractured due to large tension, meanwhile, the stability of the main tower can further avoid the phenomenon that the design value of the finished bridge root exceeds the standard due to the fact that the side pressure stress exceeds the standard, and the construction efficiency and quality of the special-shaped concrete tower column of the asymmetric cable-stayed bridge are greatly improved and ensured.
本发明公开了一种非对称斜拉桥异形混凝土塔柱施工工艺，它包括以下步骤：步骤1：塔座施工，主塔塔座为内倾45°的棱台形式，施工采用支模板浇筑混凝土施工工艺，塔座模板采用8mm厚定制钢模板。有益效果在于：本发明通过在施工前后严格把控非对称斜拉桥异形混凝土塔柱各施工阶段的浇筑、爬升以及养护等工艺，使得非对称斜拉桥异形混凝土塔柱的施工精度得到提高，有效避免了由于塔桥自身重量或施工负荷量过大而引起的弯矩现象，防止塔柱根部受到较大的拉力而引起的裂断，与此同时，主塔的稳定性还能够避免成桥根部由于侧压应力超标而导致的设计值超标的现象，大大提高确保了非对称斜拉桥异形混凝土塔柱施工效率和质量。
