探析桥梁墩柱混凝土外观质量缺陷及防治措施

Exploration on the Appearance Quality Defects and Prevention Measures of Bridge Pier Column Concrete

桥梁墩柱混凝土保护是确保桥梁质量的重要保障,也是混凝土与结构的共同工作的先决条件。桥梁工程作为重要的交通基础建设,其墩柱自身质量对结构的稳定性有着重要的作用。为解决这个问题,相关建设工作人员应从桥梁墩柱混凝土构件的外观质量问题出发,是指通过建立表面泌水率起沙、混凝土分层浇筑、混凝土离析等问题形成原因,从而找到外观品质施工控制方法,以充分发挥桥梁墩柱混凝土墩柱结构作用。

The protection of bridge pier concrete is an important guarantee for ensuring the quality of the bridge, and is also a prerequisite for the joint work of concrete and structure. As an important transportation infrastructure, the quality of the piers and columns in bridge engineering plays an important role in the stability of the structure. To solve this problem, relevant construction personnel should start from the appearance quality issue of bridge pier concrete components, which refers to establishing the causes of surface bleeding rate, sand formation, layered pouring of concrete, and concrete segregation, in order to find construction control methods for appearance quality and fully play the role of bridge pier concrete pier structure.
