摘要
上海市白龙港污水排放系统浦东工作井降水工程利用上海市二十多年的降水经验,采用非完整井理论,线性规划设计理念。尤其是在南浦大桥桥堍下,在上海市第一、二、三承压含水层相连通的含水层组中采取此种降水手段,科学设计、施工和管理降水工程保证了顶管前期工作的正常进行,既顺利地配合工作井开挖干封底,又保证了顶管出洞干施工的有效环境,同时还保障了周围环境的安全与稳定,取得了可观的社会、环境和经济效益。
The dewatering engineering at Pudong working well bid site of eilong harbour in Shanhai.We take adventage of the dewaterin experiene for more twenty years in Shanghai to design the dewatering with the non-integrity well theory and linear programming ides.Esecially near the pier of Nanpu bridge and in the confined aquifers which the first,second and third confined aquifer have direct connection each other,dewatering is important to ensure the working well normally and push pipe early to carry out,including the excavation,the bottom,push pipe going out of the working well.At the same time,dewatering has also ensured the environment steady and safty.It has a role on the society,environment and economy.
