摘要
在预制混凝土箱涵装配式人行地下通道结构中,防水技术是影响结构安全性和耐久性的重要因素,而拼接缝是预制拼装结构的薄弱节点,尤其是当预制拼装结构管节带纵向拼接缝时,使得可能发生渗漏水的位置大大增加,如果拼接缝处的防水措施不合理,将给结构的正常使用和安全性带来巨大隐患。本文以哈尔滨市某地下过街通道建设工程为背景,对预制混凝土箱涵装配式人行地下通道拼接缝处和结构整体防水性能进行探索,通过室内及现场试验证明研究结构的有效性和可靠性。
The waterproof property is the most important factor for the safety and the durability of the precast concrete box culvert fitting underpass. The juncture is weak for the precast fitting structure, and it would increase the possibility of water leakage especially when the vertical juncture is set. It would threaten the structure if the waterproof for the juncture is not reasonable. Based on the practical underpass engineering in Harbin, this paper researched on the juncture and the waterproof of the precast concrete box culvert fitting underpass. The result was proved to be effective and reliable by the experiment inside and outside.
