According to the gantry crane jacking method for assembling the TBM in the limited space of the underground engineering cavern, a hydraulic oil cylinder drives a jacking beam to move, and gradual climbing of a main beam on a stand column is achieved. According to the method, firstly, a hydraulic jacking mechanism is installed on a stand column, then a main beam is installed on the hydraulic jacking mechanism, and a first jacking beam is gradually lifted and fixed by pulling out a plug pin and starting a hydraulic oil cylinder. And then, by pulling out the plug pin, the hydraulic oil cylinder is started, and the second jacking beam is made to move and be fixed. And the steps are repeated until the main beam is driven by the hydraulic jacking mechanism to reach the designed installation height. By the adoption of the jacking method, the mode that a TBM assembly chamber is excavated in a drilling and blasting expanding mode is avoided, and installation work of the jacking gantry crane device is achieved.

    本发明提供了地下工程洞室有限空间内组装TBM的龙门吊顶升方法,通过液压油缸驱动顶升梁的运动,实现主梁在立柱上的逐步爬升。该方法首先将液压顶升机构安装在立柱上,再将主梁安装在液压顶升机构上,通过拔出插销、启动液压油缸,逐步升起第一顶升梁,并将其固定。随后,通过拔出插销、启动液压油缸,使第二顶升梁移动并固定。重复这些步骤,直至主梁在液压顶升机构的驱动下达到设计安装高度。采用这种顶升方法,避免了使用钻爆扩挖TBM组装硐室的方式,实现了顶升门吊装置的安装工作。
