混凝土建筑物水下补强加固技术研究

Study on remedial technique for fractured concrete structure in water

本文针对混凝土水下病害整治中传统围堰干法施工的缺陷， 结合工程实例， 提出水下补强加固新技术．由现场模拟施工试验并经工程实际应用表明， 这一结合防渗、整体补强水下施工技术切实可行， 水下浇筑薄层不分散混凝土各项力学性能指标， 满足工程加固设计要求， 新老混凝土结合良好．

The technique for remedy of fractured concrete structure in water is suggested. A new type of concrete, which will not scatter during poured in water, is developed. The engineering practice shows that thhe technique is effective and feasible.
