仪征市三元沟泵站工程管井的探讨

Discussion of Engineering Tubular Well in Yizheng Sanyuangou Pumping House Project

仪征平原地区为软土地基,地下水丰富,在仪征平原地区,进行水利工程和其他建筑工程施工,排水、降水是施工的关键。仪征水利工作者在平原地区水利工程施工中,积累了丰富的降水施工知识。本文通过三元沟泵站这一工程实例,总结了软土地基采用管井降低地下水的施工经验,就管井降水与轻型井点降水的应用条件、降水管井的计算与施工进行了探讨,以作为类似工程施工的借鉴。

Yizheng plains are provided with soft soil foundation and rich groundwater.Water drainage and elimination are important for constructing water conservancy projects and other construction works in Yizheng plains.Yizheng water conservancy construction workers have accumulated a wealth of knowledge in the aspect of construction precipitation from water conservation project construction in the plains.In this paper,the construction experience of reducing underground water by tubular well in soft soil foundation is summed up with Sanyuangou pumping house as an engineering example.The application condition of tubular well water elimination and light-type well water elimination,calculation and construction of water elimination tubular well are discussed,thereby providing reference for constructing similar projects.
