摘要
预应力钢丝绳-聚合物砂浆加固法是一种新型的混凝土结构加固技术,其原理是在梁底采用预应力钢丝绳施加预应力,并采用聚合物砂浆对钢丝绳进行包裹。由于该加固技术在湖南属于首例,在技术方案及施工工艺方面有待优化改善。本文结合现场实际情况,对预应力钢丝绳-聚合物砂浆加固技术进行了完善,对施工工艺提出详细的要求。
The reinforcement method of Prestressing wire rope-Polymer mortar is a new concrete structure reinforced technology, The principle is that prestressed with prestressed steel wire rope in the bottom of beams, and wrapped wire rope with polymer mortar. As the first of its kind reinforcement technology in Hunan, in terms of technical solutions and construction techniques to be optimized and improved. This article combined with the actual situation, carried out to improve on the reinforcement method of Prestressing wire rope-Polymer mortar, and made details demands of the construction process.
