Temporary counterweight control method and system for concrete bridge cantilever closure construction
The invention relates to the technical field of bridge construction, in particular to a temporary counterweight control method and system for concrete bridge cantilever closure construction. Comprising the following steps that S1, the mass of a counter weight is determined according to the weight of a closure section, and the counter weight with the adjusted mass is hoisted to the position of a main pier on a main beam; s2, a counter weight is driven to move to the cantilever end of the main beam from the main pier in the bridge direction; and S3, closure section concrete is poured, the counter weight is driven to move towards one side of the main pier in the bridge direction according to the concrete pouring condition, and the deflection of the cantilever end of the main beam is kept unchanged all the time till closure section construction is completed. The concrete bridge cantilever closure construction temporary counterweight mode is very simple, the deflection of the cantilever end of the main beam is controlled by moving in the bridge direction, the concrete pouring stability of the closure section is improved, the pouring quality of the closure section is greatly improved, the overall adjustment precision is very high, and the concrete bridge cantilever closure construction temporary counterweight has great popularization value.
本发明涉及桥梁建设技术领域，具体地指一种混凝土桥梁悬臂合龙施工临时配重控制方法及控制系统。包括以下步骤：S1、根据合龙段重量确定配重物质量，将调整好质量的配重物吊装到主梁上主墩位置；S2、驱动配重物沿顺桥向从主墩移动至主梁的悬臂端；S3、开始浇筑合龙段混凝土，并且根据混凝土浇筑情况驱动配重物沿顺桥向向主墩一侧移动，使主梁的悬臂端挠度始终维持不变，直至完成合龙段施工。本申请的混凝土桥梁悬臂合龙施工临时配重方式非常简单，通过顺桥向移动的方式对主梁悬臂端的挠度进行控制，提高了合龙段混凝土浇筑的稳定性，大幅度提升了合龙段的浇筑质量，整体调节的精度极高，具有极大的推广价值。
