Large-span bent cap few-support closure construction method for underneath pass of existing bridge
The construction method comprises the steps that a cross beam installation area is divided into a limited area and an unlimited area, an outer wrapping plate is installed on the top of a pier stand column, concrete is poured on the inner side of the outer wrapping plate, and then a supporting structure and a first jack are installed on the outer side of the outer wrapping plate; a vertical support is built in the open area, a traction assembly is installed on the top of the vertical support, the cross beam is lifted to the position above one pier stand column in the limited area, a first jack on the top of the pier stand column supports the bottom of the cross beam, and the traction assembly draws the cross beam; when the cross beam moves to the position above the two pier stand columns in the limited area, the first jack shrinks downwards, and the cross beam is erected to the cast-in-place sections of the two pier stand columns; and the cross beams are hoisted to the tops of the pier stand columns in the open area, and closing construction is conducted on the cross beams in the limited area and the open area. The method has the effect of reducing the occupation of the lower traffic road surface.
本申请公开了一种下穿既有桥梁大跨度盖梁少支架合龙施工方法，通过将横梁安装区域划分为受限制区域和无受限区域，在桥墩立柱顶部安装外包板，在外包板内侧浇筑混凝土，然后在外包板外侧安装支撑结构以及第一千斤顶，在开放区域处搭建竖向支架，并在竖向支架的顶部安装牵引组件，将横梁起吊至受限区域处的其中一个桥墩立柱的上方，桥墩立柱顶部的第一千斤顶对横梁底部进行支撑，牵引组件对横梁进行牵拉，直至横梁移位至受限区域处的两个桥墩立柱上方，第一千斤顶向下收缩，使横梁架放至两个桥墩立柱的现浇段；将横梁吊放至开放区域的桥墩立柱顶部，并对受限区域以及开放区域的横梁进行合拢施工。本申请具有减少对下部通车路面的占用的效果。
