沉井在泵站工程中的应用

Application of Open Caisson in Pumping Station Engineering

该文以杭州某污水厂进水管中的提升泵站工程为例,介绍了沉井施工技术在泵站工程中的应用。在施工方案优化的基础上,在粉砂地质条件下沉井下沉技术作了其重点、难点的分析,并提出一系列相应的对策。其成果为同类型沉井施工技术积累了宝贵的经验。

Taking the lifting pumping station project in the influent pipeline of a wastewater treatment plant as an example, the article introduces the application of open caisson construction technology in the pumping station engineering. On the basis of construction scheme optimization, the article analyzes the keynote and difficulty of the open caisson sinking technology under the condition of silt geology, and proposes a series of relative countermeasures. The result can be referred for the construction of similar open caissons.
