厦门海沧大桥混凝土裂缝补强灌浆处理

Consolidation grouting for concrete cracks at Xiamen Haicang Bridge

大型混凝土结构浇注过程中遇气温骤降 ,难免会产生收缩裂缝。采用 EFN系列弹性环氧补强固结灌浆材料对厦门海沧大桥箱形基础裂缝进行灌浆处理 ,效果良好。详述了浆材选择、注浆压力设定。

In a large scale pouring concrete structure,contruction cracks can hardly be avoided as temperature suddenly drops.It achieved good results that the cracks of the box foundation of Xiamen Haicang Bridge were treated by using the EFN elastic epoxy consolidation grouting material.The material selection,grouting pressure set up, construction technology and result detection are represented in detail in the paper.
