A-type leaning tower construction method
The invention relates to the technical field of bridge construction, and particularly discloses an A-type leaning tower construction method which specifically comprises the following steps: according to the overall height of a tower column, the connecting position of a cross brace in the horizontal direction of the tower column is obtained through structural checking calculation; the two tower columns are symmetrically and synchronously constructed in a segmented mode; wherein in the construction process of the two tower columns, the cross brace is installed according to the connecting position, so that the two ends of the cross brace are connected with the two tower columns correspondingly, and jacking force is applied to the two tower columns through the cross brace; after the tower columns are constructed to the installation height of a temporary inhaul cable, the temporary inhaul cable is installed and tensioned; the construction is finished; and a permanent inhaul cable is installed, and the cross brace and the temporary inhaul cable are dismantled. The jacking force value of the cross brace and the cable force value of the temporary inhaul cable can be adjusted in real time according to the actual stress state of the tower column in the construction process, and it is ensured that the stress state of the whole leaning tower column in the construction stage is within the controllable range.
本发明涉及桥梁施工技术领域，具体公开了一种A型斜塔施工方法，具体包括以下步骤：根据塔柱整体高度，通过结构验算得到横撑在塔柱水平方向的连接位置；采用分段对称同步施工两根塔柱；其中，在两根塔柱施工过程中根据连接位置进行横撑安装使得横撑的两端分别两根塔柱连接并通过横撑对两根塔柱施工顶力；在塔柱施工到临时拉索安装高度后，进行临时拉索安装并张拉；施工完毕；安装永久拉索，拆除横撑和临时拉索。本发明能够在施工过程中根据塔柱的实际应力状态，实时调整横撑的顶力值及临时拉索的索力值，确保施工阶段整个斜塔塔柱的应力状态在可控范围之内。
