摘要
连云港近海区域工程地质条件较差,属于海淤沉积软土地质,沉井施工普遍存在难度高、风险大、工期长、容易产生偏沉及超沉等问题。连云港市徐圩新区应急备用水源取水泵站工程吸水井属于超大沉井,为保证施工安全和下沉稳定可控,各参建单位积极探索沉井施工工艺方法,经严格设计论证并采取有效措施,取得了较好的实际效果,对同类型工程施工具有一定的借鉴意义。
The engineering geological conditions of Lianyungang offshore area are poor,which belongs to the soft soil geology of sea deposition.The open caisson construction generally has some problems,such as high difficulty,high risk,long construction period,prone to partial settlement and over settlement.The suction well of the emergency standby water intake pump station project in Xuwei new area of Lianyungang City belongs to a super large open caisson.In order to ensure the construction safety and stable and controllable sinking,all participating units actively explore the open caisson construction technology and methods.After strict design demonstration and taking effective measures,good practical results have been achieved,which can be used for reference for the construction of similar projects.
