泥水平衡法和网格水冲法3m顶管费用分析

Cost Analysis of 3 m Pipe Jacking by Grid Water Flush Method and Mud-water Balance Method

根据太原人民路雨水工程特点,对工程地质为富水砂层和粉质粘土层,直径3 m钢筋混凝土管采用泥水平衡式和网格水冲式顶管方法费用进行分析对比,提出哪种方法更经济以及该大直径顶管工程成本控制的关键,为其他类似工程的施工提供参考。

Based on the characteristics of the rainwater project of Taiyuan Renmin Road,the cost of the engineering geology is water-rich sand layer and silty clay layer,and the diameter of the 3 m reinforced concrete pipe is analyzed and compared with the mudwater balance and grid water flushing pipe jacking methods.More economical and the key to the cost control of this large diameter pipe jacking project provides a reference for the construction of other similar projects.
