Abstract

The invention discloses a TBM tunnel face front rock mass integrity drilling device and method. The drilling device comprises a drilling assembly, a drilling machine posture control assembly, a data monitoring assembly and a TBM drilling machine platform fixing base. The drilling assembly is connected with a TBM hydraulic system to obtain power, and the alloy drill bit rotates and horizontally moves to drill a rock mass. The drilling machine posture control assembly is used for controlling the angle, direction and position of a drill rod and keeping drilling accuracy and stability. The data monitoring assembly obtains and stores drilling mechanical response signals through a high-precision sensor and a data module so as to analyze rock mass integrity characteristics. The TBM drilling machine platform fixing base is used for achieving TBM carrying of a drilling device. The rock mass integrity parameters in front of the tunnel face of the TBM are interpreted through drilling and mechanical response information of the drilling device, the in-situ device and method are used for obtaining engineering geological survey data, and important support is provided for safe and efficient tunneling of the TBM.

Description

technical field [0001] The invention relates to the field of tunnels and underground engineering, in particular to a device and a method suitable for advanced engineering geological exploration of open and shield TBMs and integrity measurement of rock masses in front of tunnel faces. Background technique [0002] Full-face tunnel boring machine (TBM) technology is currently widely used in the domestic tunnel and underground engineering fields, especially in the construction of deep and long tunnels. However, TBM is more sensitive to the integrity of rock mass. On the one hand, in rock mass with good integrity, TBM is prone to situations such as "digging is not moving, and the speed is slow". On the other hand, in a rock mass with poor integrity, if the exploration of the geological conditions ahead is not clear, TBM is prone to accidents such as jamming and engineering instability. Therefore, the integrity survey of the rock mass in front of the TBM tunnel face is an import...
