在盾构施工中,每台盾构都有其特定的适应范围。在绝大多数情况下,是在特定适应范围的基础上通过对现有盾构进行或维修改造或升级扩容以求达到对工程实际情况的全面适应性。本文针对盾构环流系统能力不足的情况,在现有设备的基础上通过合理的设计系统、配置硬件和软件系统使之有效地运行起来,成功实现了环流系统的升级扩容,解决了环流系统运力不足的情况,满足了工程实际情况的需要。 In the shield construction, each shield has its own specific range of adaptation. In the vast majority of cases, the existing shields are retrofitted or upgraded to meet the actual conditions of the project on the basis of a specific scope of adaptation. In this paper, in view of the lack of capacity of the shield circulation system, based on the existing equipment, through the reasonable design of the system, the configuration of the hardware and software system to make it operate effectively, the circulation system has been successfully upgraded and expanded to solve the problems of circulation system capacity Insufficient situation, to meet the needs of the actual situation of the project.
