随着我国加快城市化进程,土地资源越来越稀缺,因而建筑物或构筑物的发展方向就转向地下和空中,尤其是地下工程迅速发展起来。地下施工一般要求质量高、速度快等。对于体量很大的地下基础工程,按照结构设计规范常常设置大量的后浇带,如采用加强带无缝浇筑施工取代后浇带方案,可实现超长构筑物的连续浇筑作业,混凝土一次成型,增加了混凝土的密实度,提高了混凝土的强度及抗裂、防渗性能,同时还能缩短工期,效益显著。
As China accelerates the process of urbanization and its land resources become increasingly scarce, the direction of the development of buildings or structures turns to the underground and the sky, especially the underground projects are rapidly developing. Underground construction generally require high quality, fast and so on. For a large amount of underground foundation works, according to the structural design specifications often set a large number of post-pouring tape, such as the use of reinforced seamless pouring construction instead of pouring after the program can be achieved long pouring continuous construction operations, a concrete forming, Increase the density of concrete, improve the strength of concrete and cracking, impermeability, but also shorten the construction period, significant benefits.
