摘　　要：沉井施工具有占地面积小、不需板桩支护、对邻近建筑物影响较小、施工安全等优点,在施工技术和施工机械不断改进的今天得到了广泛应用,但是大型不规则双壁沉井在施工中还存在一定难度。结合工程实例,针对排水泵站采用大型不规则双壁沉井作为地下结构,在设计、施工方面应注意的主要问题和一些具体做法进行了详细介绍,重点对大型不规则双壁沉井下沉工艺、下沉监测和垂直、水平纠偏技术作了论述,以供有关人员在今后施工中参考。Caisson construction has many advantages ,such as having a small footprint, no support of sheet pile , little impact on adjacent buildings and security of construction . The caisson technology is widely applied as the developing of the construction technology and machinery today, but some difficulties indeed exist in the construction of the large-scale irregular double-wall caisson. In this paper, some engineering instances are involved. In view of using a large-scale irregular caisson with double walls in a drainage pumping station, this article presents the problems of design and construction, the solutions and its effect during the application . This article also introduces the sinking technology ,monitoring system and the method of vertical correction in detail .
