西咸新区某污水处理厂粗格栅沉井工程降水设计优化与分析

OPTIMIZATION AND ANALYSIS OF DEWATERING DESIGN FOR COARSE-GRID CAISSON PROJECT OF A SEWAGE TREATMENT PLANT IN XIXIAN NEW DISTRICT

作为地下大型循环水泵房沉井施工的基础工程之一,沉井开挖支护及降水的设计施工质量是整个工程的关键。以西咸新区某地下工程为例,介绍沉井支护及降水施工设计方案,从施工可行性、经济性和质量安全可靠性三方面进行分析,以期为相关技术人员提供设计参考。

As one of the basic projects for the construction of the caisson of a large underground circulating water pump house,the design and construction quality of the excavation,support and precipitation of the caisson is the key to the entire project.Taking an underground project in Xixian New District as an example,the design plan for caisson support and dewatering construction is introduced,and the analysis is caried out from three aspects of construction feasibility,economy,and quality,safety and reliability,in order to provide design references for relevant technical personnel.
