Construction and Installation Technology of Large-span Super-high Single-story Steel Structural Factory Building

摘要:

结合公铁并行条件下某一级公路软基施工的案例，针对场地范围内软土分布广且深厚的情况，保证公路施工及运营期间对城轨的影响降至最低，软基处理采用碎石注浆桩加固处理，充分发挥其对既有建筑及基础的影响较小及施工安全可靠的优势，阐述碎石注浆桩的施工方法和监测。其成果对碎石注浆桩在公铁并行条件下公路工程的施工具有参考应用价值。

Abstract:

Through the construction of a large-span steel structural factory building of a cold rolling project second tender section in a large iron and steel group in China, combined with the successful experience of steel structure construction and installation of previous projects, the installation and construction methods of large-span super-high single-story steel structure factory building are expounded. Under the premise of ensuring the safety and quality, the scientific construction methods are used to quicken the engineering progress and solve the difficulties in the construction of large-span super-high single-story steel structural factory building, which can provide the corresponding reference for the construction of similar projects.
