Problems solved by technology

Does not apply to non-equipped dual-shield TBMs
[0006] The inventor found in the research that the geophone is an important part of the seismic wave method. In the drill and blast method or the open TBM tunnel, the vertebral fixed geophone was inserted through the anchoring agent or drilled in the side wall, but in the double-shield TBM tunnel In the middle, due to the impact of the segment, the installation of the geophone is limited, and the geophone cannot be installed directly on the surrounding rock, and there is a gap between the segment and the surrounding rock, and there is a strong reflection interface, which seriously affects the data quality. Segment installation signal is not good

Abstract

The invention provides an auxiliary signal acquisition device and system for seismic wave advanced detection of a double-shield TBM. The device comprises a duct piece and a conduction rod, the duct piece is provided with a pouring hole, one end of the conduction rod is directly attached to surrounding rock through the pouring hole, and the other end of the conduction rod exceeds the inner wall ofthe duct piece to the outer side. According to the technical scheme, the auxiliary signal device suitable for seismic wave advanced detection of a double-shield TBM not only needs to fully utilize anexisting segment structure of a double-shield TBM, but also needs to be easy and convenient to operate and not to affect the construction progress of the TBM.

Description

technical field [0001] The disclosure belongs to the field of seismic exploration, and in particular relates to an auxiliary signal acquisition device and system for double-shield TBM seismic wave advance detection. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] During the construction of tunnels and underground projects in transportation, water conservancy, municipal engineering, etc., due to the complex and changeable geological conditions and the limitation of the existing technical level, the initial level of exploration cannot fully detect the unfavorable geology on the excavation axis. Especially in TBM construction tunnels, the adaptability of the roadheader to geological conditions is poor, and accidents such as machine jams frequently occur due to failure to adopt a reasonable construction plan in unfavorable geological sections...
