摘要
针对在上海市上中路隧道工程施工的Φ14.87 m超大直径泥水气平衡盾构,介绍了其液压推进系统的功能、泵组控制、分区设计、单个分区的液压控制方式。结果表明:盾构液压推进系统满足了盾构总推力及速度控制要求,提高了管片拼装效率;比例减压控制策略满足了工程需要。
The function, pump package control, partition design and hydraulic control mode for single partition of hydraulic propulsion system are introduced in terms of Ф14.87 m exceed diameter mud-water-air balance shield machine used in Shangzhong Road Tunnel of Shanghai. The study shows that the hydraulic propulsion system meets needs of the gross propulsion and speed control, enhances the assembly efficiency of duct pieces; the strategy of pressure reducing by proportions satisfies project needs.
