一、概述混凝土和钢筋混凝土工程发生裂缝或剥落现象,在维修过程中不论水上水下多半采用外包法(使用胶结材料在建筑物外部包起),这样既不影响建筑物的使用又不破坏建筑物本身的强度,自重压力堆石灌浆法是一种快速简便而又保证质量的方法,现就某桥桩修复工程为例作一介绍(见图1)。 First, an overview of concrete and reinforced concrete cracks or spalling phenomenon, in the maintenance process regardless of underwater and underwater most of the use of outsourcing (using cementitious materials in the building outside the package), so that neither affect the use of buildings without damaging the building The strength of the material itself, self-weight rockfill grouting method is a quick and easy but also to ensure the quality of the method, is a bridge repair project as an example (see Figure 1).
