The Changsha Municipal Government StationLeifengdadao Station mined section on ChangshaZhuzhouXiangtan intercity railway has to cross underneath Xiyuan Hotel on the ground. A series of technologies, including using hydraulic fracturing machine,milling machine, hydraulic hammer and submersible drilling rig + hydraulic hammer, have been adopted and put into comparison. In the end, the method of submersible drilling rig + hydraulic hammer is chose, and the safety of building is guaranteed.
