Abstract

The invention discloses a combined-type tunnel boring machine (TBM) for achieving geological exploration, and a geological exploration tunneling method, and relates to the field of tunnel and underground engineering construction. The combined-type TBM for achieving geological exploration comprises an advance TBM body and an expanding excavation TBM body; the expanding excavation TBM body surroundsthe outer side of the advance TBM body; the advance TBM body is carried with a ground-penetrating radar device, a geological drilling rig, an acoustic exploration device and a micro-seismic monitoring device; through excavation of the advance TBM body, the geological situation in front of the tunnel face can be directly exposed; and the advance TBM body can be carried with various advance geological exploration devices, the geological situation in front of the tunnel face of the advance TBM body can be forecasted, and the geological environment in front of the tunnel face of the expanding excavation TBM body can also be forecasted. According to the geological exploration tunneling method, various advance geological exploration is conducted during excavation, the engineering geological andhydrology geological structures in front of and around the tunnel face are accurately forecasted, thus geological disasters of TBM construction engineering are effectively avoided, the construction safety is guaranteed, the progress is accelerated, and the cost is saved.

Description

technical field [0001] The invention relates to the field of tunnel and underground engineering construction, in particular to a combined TBM (Tunnel Boring Machine, full-section tunnel boring machine) for realizing geological exploration and a geological exploration and excavation method. Background technique [0002] At present, the prevention and control of geological disasters in tunnel and underground engineering construction is an urgent technical problem to be solved. The deep burial conditions of deep tunnels determine the complexity of their geological conditions, and the corresponding survey is difficult. Advanced geological prediction is One of the key technologies to solve this technical problem. Advanced geological prediction refers to the detection of geological conditions around the tunnel and in front of the tunnel face before excavation and during construction, to identify and predict the engineering geological and hydrogeological structures in front of and ...
