摘要
河流穿越工程成功与否的关键工作是施工导流与施工期降排水。辽河穿越工程施工,采用挖掘机结合挖泥船的开挖方案,在保证效率的同时降低了成本;采用井点降水的方式,在理论计算的基础上结合工程经验,合理确定井点降水参数,成功在2.5 km的河床内实现全部干地施工;通过科学合理的导流、降水、开挖方案,成功压缩工期4个月,节约建设成本约300万元。
The key work of the success for river crossing project is the construction diversion and dewatering during construction period. The excavation scheme of excavators combine with dredges is adopted to ensure the efficiency and reduce the cost for the crossing the Liaohe river construction project. Through the theoretical calculations and the engineering experience, the way of the well-point dewatering is adopted to determine reasonably the parameters of the well-point dewatering, then the all construction in dry land is realized successfully in the 2.5 km river bed. Because of the scientific and reasonable construction scheme of the river diversion,dewatering and the excavation, the construction period is shortened by 4 months and the construction costs are saved up to3 million RMB.
