砾石破碎型泥水平衡顶管机的选型方法

Selection of GravelBreakup Type Slurry Balance Pipe Jacking Machine

结合西气东输黄河顶管的施工,通过工程地质要求、设备性能要求、泥水平衡方式、刀盘刀具等破碎技术的阐述,介绍超长距离、大深度、大口径、高精度、砾石破碎型泥水平衡顶管机的选型方法。黄河顶管工程的成功穿越,充分证明砾石破碎型泥水平衡顶管机的选型是成功的,取得了预期的社会经济效益。

With the Yellow River pipe jacking project in “West-East Gas Transmission” scheme as the background and according to the engineering geological conditions, equipment performance requirements, slurry balance mode, cutter head and crushing technology etc., the paper introduces how to select the high precision gravel breakup type slurry balance pipe jacking machine for the long distance, deep, large diameter drive under complicated geological conditions. The completion of Yellow River pipe jacking fully proves that the type-choosing of gravel breakup type slurry balance pipe jacking machine is successful with the expected social and economic benefits acquired.
