Prestress prepressing method for bridge 0 # block construction support
The invention provides a prestress preloading method for a bridge 0 # block construction support. The prestress pre-pressing method for the bridge 0 # block construction support comprises the following steps that S1, bridge design is conducted, specifically, in the first step, a main bridge is designed, the size of a left bearing platform and a right bearing platform of a 12 # pier and the size of a left bearing platform and the size of a right bearing platform of a 13 # pier are both 10.6 m * 10.6 m * 3.5 m, the height of the 12 # pier is 15 m, the height of the 13 # pier is 14.5 m, and bridge pier information is shown in the figure 1-4; secondly, the heights of pier bodies of a 12 # pier and a 13 # pier of a main bridge of the bridge are 15 m and 14.5 m respectively, the overall length of a 0 # section is 12 m, each side is suspended out of the pier body by 4 m, and 820 consolidation steel pipe steel stand columns are welded to a support through embedded parts on a bearing platform. The prestress pre-pressing method for the bridge 0 # block construction support has the advantages that the prestress pre-pressing method is simple and convenient, high in safety and more superior for projects with high bridge piers and narrow construction sites, and therefore the prestress pre-pressing method can be more suitable for carrying out stress testing on the pressure bearing capacity of various pressure bearing pieces.
本发明提供一种用于桥梁0#块施工支架的预应力预压方法。所述用于桥梁0#块施工支架的预应力预压方法包括以下步骤：S1.桥梁设计，所述桥梁设计如下：第一步骤、主桥设计：12#墩、13#墩左右幅承台尺寸均为10.6m×10.6m×3.5m，12#墩高为15m，13#墩高14.5m，桥墩信息如图1－4所示；第二步骤、大桥主桥12#、13#墩墩身高度分别为15m、14.5m，0#段全长12m，每边悬出墩身4m，支架利用承台上预埋件焊接820固结钢管钢立柱。本发明提供的用于桥梁0#块施工支架的预应力预压方法简单便捷，安全性高，且对于桥墩高、施工场地狭小的项目更具优越性，进而可以更加适合对各种承压件的承压能力进行受力验的优点。
