隧道注浆材料的研究与应用

Research on Tunnel Grouting Material and Its Application

当前我国正大规模进行道路改造升级,而我国南方地区多山地丘陵,道路建设中开挖隧道较多,且当地靠近海边,混凝土结构易被离子侵蚀.故本文致力于设计一种堵水效果优良、流动性好、水下抗分散性能强、初终凝间隔短的注浆材料,填充密实衬砌后的缝隙,改善隧道的耐久性,提高我国隧道行业的建设水平.

At present, it is carrying out to upgrade the roads in large-scale in China. However, there are many mountainous and hilly areas in southern China, and many tunnels are excavated during road construction. The local area is close to the sea, and the concrete structure is prone to be eroded by ions. Therefore, this paper aims to design a kind of grouting material with excellent water plugging effect, good fluidity, strong underwater anti-dispersion and short interval between initial and final setting, so as to fill the gap at the back of the lining, improve the durability of the tunnel and enhance the construction level of China ' s tunnel industry.
