Circulating pouring method for UHPC reinforced water pier column concrete
The invention discloses a circulating pouring method for UHPC reinforced water pier column concrete.The to-be-increased section area of a pier column is provided with a concrete pouring formwork, the inner side of the concrete pouring formwork is provided with an articulated chute, and the circulating pouring method comprises the following steps that S1, an overhead rail system is installed at the bottom of a beam body, and a rail running car is slidably connected to the overhead rail system; a hoisting mechanism is connected to the rail running car; s2, the UHPC concrete is conveyed to a bridge floor and unloaded to a hopper; s3, the hopper is hoisted to the cofferdam water diversion tip platform, and connection between hoisting equipment and the hopper is relieved; and S4, the hopper is connected with a hoisting mechanism, the hopper is driven to move to the pouring point through the rail running car and the hoisting mechanism, and concrete is poured to the inner side of the concrete pouring formwork through the articulated chute. According to the invention, the overhead rail system is arranged at the bottom of the beam and is matched with light equipment such as a hoisting mechanism and a sports car, so that water UHPC pouring can be realized, the construction water area is not occupied, and the environmental influence requirements of bridge major and medium repair projects on the water area with important navigation significance are met.
本发明公开了一种UHPC加固水上墩柱混凝土的循环浇筑方法，墩柱待增大截面区域安装有混凝土浇筑模板，混凝土浇筑模板的内侧设置有溜管，包括以下步骤：S1、在梁体底部安装吊轨系统，所述吊轨系统上滑动连接有轨道跑车，所述轨道跑车上连接有起吊机构；S2、UHPC混凝土运送至桥面并卸料至料斗；S3、吊装料斗至围堰分水尖平台上，解除起吊设备与料斗的连接；S4、料斗与起吊机构连接，通过轨道跑车和起吊机构带动料斗移动至浇筑点处，通过溜管向混凝土浇筑模板内侧浇筑混凝土。本发明通过在梁底布置吊轨系统系统，配合起吊机构及跑车等轻型设备即可实现水上UHPC混凝土浇筑，不侵占施工水域，满足具有重要通航意义的水域上的桥梁大中修工程环境影响要求。
