Large-span double-limb thin-wall hollow high pier zero block bracket pre-pressing construction method
The invention provides a pre-pressing construction method for a large-span double-limb thin-wall hollow high pier zero block bracket. The pre-pressing construction method comprises the following steps that S10, a triangular bracket is installed, and a first distribution beam is arranged; s20, a supporting beam bracket and a second distribution beam are arranged; first bailey beams are anchored to the left side and the right side of the upper portion of each single-limb pier body in the transverse bridge direction, first jacks are arranged between the first bailey beams and the first distribution beams on the corresponding sides of the first bailey beams, and the first distribution beams are loaded and pre-pressed through the first jacks; a second bailey beam is anchored over the double-limb pier in the transverse bridge direction, a second jack is arranged between the second bailey beam and the second distribution beam, and the second distribution beam is loaded and pre-pressed through the second jack; and S40, loading pre-pressing construction is carried out. According to the method, the technical problem that the bracket between the two limbs cannot be pre-pressed is solved, the loading and unloading construction efficiency is improved, the construction time is saved, and the early-stage complex and time-consuming process of manufacturing a special counter-force beam is omitted.
本发明提供了一种大跨双肢薄壁空心高墩零号块托架预压施工方法，包括以下步骤：S10:三角托架的安装及第一分配梁的设置；S20：支撑梁托架及第二分配梁的设置；S30：反力贝雷梁的设置：在每个单肢墩身上方左、右侧位置横桥向分别锚固第一贝雷梁，第一贝雷梁和其对应侧第一分配梁之间设有第一千斤顶，通过第一千斤顶对第一分配梁加载预压；在双肢墩正上方横桥向锚固第二贝雷梁，第二贝雷梁和第二分配梁之间布置有第二千斤顶，通过第二千斤顶对第二分配梁加载预压；S40：加载预压施工。本方法解决了双肢间托架无法预压的技术难题，提高了加载、卸载的施工效率，节约施工时间，又免去前期复杂耗时的制作专用反力梁的过程。
