主要阐述了地下工程混凝土结构存在的渗漏问题,以及早期智能养护技术在地下混凝土结构中的应用对策。通过长沙地铁4号线一期工程的实践,得到的结论是:早期智能养护技术可以广泛应用于地下工程的混凝土养护中,不但大大减少了混凝土的裂缝,提高了结构的耐久性和安全性,而且节约了大量的工作量。
Mainly described the leakage of concrete structures underground engineering problems, as well as early intelligent maintenance technology in underground concrete structures in the application of countermeasures. Through the practice of the first phase project of Changsha Metro Line 4, it is concluded that the early intelligent maintenance technology can be widely used in the concrete curing of underground works, not only greatly reducing the concrete cracks and improving the durability and safety of the structure, And save a lot of workload.
