Construction method for large-span and large-size bent cap of transition pier of superposed beam cable-stayed bridge
The invention relates to a construction method for a large-span and large-size bent cap of a transition pier of a superposed beam cable-stayed bridge. The construction method comprises the following steps that firstly, chiseling is conducted on the top of a pier column; secondly, a support is installed; thirdly, a first bracket and a first embedded part are installed, and a second bracket and a second embedded part are installed; fourthly, the first distributive girder is installed; fifthly, the bailey beams are installed; sixthly, a second distribution beam, a third distribution beam and a bottom die are installed; seventhly, a bent cap steel reinforcement framework and a side mold are installed; eighthly, concrete is poured in a layered mode; and ninthly, the support is dismantled. The first bracket and the second bracket are arranged to support the whole support, the bailey beam is erected on the first bracket and the second bracket, so that the stability of the bailey beam is guaranteed, erecting of the whole support is not affected by the terrain, and good supporting performance can be achieved for construction of a large cover beam.
本申请涉及一种叠合梁斜拉桥过渡墩大跨径、大体积盖梁施工方法，包括以下步骤：步骤一，墩柱顶部凿毛；步骤二，支架安装；步骤三，第一托架、第一预埋件以及第二托架、第二预埋件安装；步骤四，第一分配梁安装；步骤五，贝雷梁安装；步骤六，第二分配梁、第三分配梁以及底模安装；步骤七，盖梁钢筋骨架及侧模安装；步骤八，混凝土分层浇筑；步骤九，拆除支架。本申请通过设置第一托架和第二托架作为整个支架的支撑，贝雷梁的搭建位于第一托架和第二托架上，使得贝雷梁的稳固性得到保证，整个支架的搭建不受地势的影响，能对重大盖梁的施工起到良好的支撑性。
