城市地下道路明挖预制拼装工艺研究与实践

Study and Practice on Excavation Prefabricated Assembly Process of Urban Underground Road

主要介绍1种下穿通道双向预制拼装工艺和实践案例。在城市浅埋地下道路施工中,该工艺相比常规明挖现浇施工,在施工工期、交通干扰、环境影响、质量保证等方面体现出较大的优势。该工艺在实际案例中实现了良好的效果,证明了工艺的可行性与推广价值。

this paper introduces a two-way prefabricated assembling process and practice case of under passes.In the construction of shallow buried underground road in city,the technology has more advantages than the conventional open excavation construction in construction period,traffic interference,environmental impact,quality assurance and so on.The process achieves good results in practical cases,and proves the feasibility and popularization value of the process.
