Bridge construction method of unbalanced continuous beam
The invention provides a bridge construction method for an unbalanced continuous beam, which comprises the following steps of: under the condition that a hanging basket is moved to a lower section after a symmetric section is constructed, performing construction in a manner of pre-pressing and balancing the weight of the previous section before pouring so as to balance the stress on two sides of a cantilever twice, and comprising the following steps of: constructing a 0 # block and a 1 # block on a stand column of a bridge; the bridge buttress with the starting section is obtained; a stand column of the 0 # block serves as a temporary buttress, a temporary support is installed on the temporary buttress, and a temporary support system is formed; the bridge buttress with the starting section is tensioned, so that hanging baskets are assembled on the two sides of the bridge buttress; standard segment construction is conducted, and the hanging basket is moved; the side span closure sections are constructed on the standard sections; the middle span section is constructed on the side span closure section; and the temporary support system and the balance weight are dismantled.
本发明提供了一种不平衡连续梁的桥梁施工方法，包括：在对称段施工完挂篮移至下节段的情况下，采用浇筑前对上一段节进行预压配重的方式进行施工，以平衡悬臂两次两侧的受力，包括如下步骤：对桥梁的立柱上进行0#块和1#块的施工，得到具有起步节段的桥梁支墩；以所述0#块的立柱为临时支墩，在所述临时支墩上安装临时支架，形成临时支架系统；对所述具有起步节段的桥梁支墩进行张拉，以在所述桥梁支墩两侧拼装挂篮；进行标准节段施工并移动挂篮；在所述标准节段上对所述边跨合龙段进行施工；在所述边跨合龙段上对中跨段进行施工；拆除所述临时支架系统和所述配重。
