摘要
以陕西汉中龙岗大桥为例,介绍其副塔上端锚室密封防护施工方案,重点阐述了环保材料的使用和施工工艺的改进。在工程施工中,采用环保型聚氨酯灌注胶代替传统非硫化密封胶,性能优良,能起到优异的密封防护效果。
The article took Shaanxi Hanzhong Longgang Bridge as an example to introduce the sealing and protecting construction scheme of the anchor chamber, and elaborated application of environmental friendly material and improvement of construction technology. During project construction, the traditional non-vulcanization sealant was substituted by environmentally friendly polyurethane pouring sealants, which had excellent performance and good sealing-protection effect.
