深水码头港池干开挖深井降水设计

深井降水是一种设备简单、排水效率高的降水方法,在地下工程的施工中受到广泛应用。文章以埃及苏赫纳第二集装箱码头项目超大港池深井降水干开挖为例,对于地层主要为砂卵砾石层,开挖深度大,降水面积大等特点,阐述了降水设计、实施和运行过程,为类似地质条件、码头设计的工程施工作为参考和借鉴。

Deep well dewatering is a dewatering method with simple equipment and high drainage efficiency,which is widely used in the construction of underground engineering.Taking the dry excavation of deep well dewatering in the super-large port pool of the second container terminal project in Suhena,Egypt as an example,this paper expounds the design,implementation and operation of dewatering for the characteristics of sand-gravel layer,large excavation depth and large dewatering area,which can be used as a reference for the engineering construction of similar geological conditions and wharf design.
