大型沉井在软弱地基及周边环境复杂工况条件下的预处理施工技术措施
|
摘要
以浙能镇海电厂燃煤机组搬迁改造项目中的循环水泵房大型沉井施工为研究对象。在沉井制作前,通过改良地基承载力、加强现场监督管理、建立稳妥的监测系统等预处理施工技术措施,确保了周边环境安全,同时为后续循环水泵房沉井制作及下沉提供了可靠的保证。可供今后类似复杂工况下大型沉井施工参考。
The construction of large caisson of circulating water pump house in the relocation and reconstruction project of coal-fired units of Zheneng Zhenhai Power Plant is taken as the research object.Before the caisson fabrication,the surrounding environment is ensured by improving the foundation bearing capacity,strengthening the on-site supervision and management,and establishing a good monitoring system,and other pretreatment construction technology measures.At the same time,it provides a reliable guarantee for the subsequent caisson fabrication and sinking of circulating pump house.It can provide reference for large caisson construction under similar complex working conditions in the future.
