摘要： A drilling device for surveying front rock-mass intactness of a tunnel face for a tunnel constructed by a TBM and a method using the same are provided. The drilling device includes a drilling assembly, a drill-attitude control assembly, a data monitoring assembly and a TBM-platform fixing seat. The drilling assembly is connected to a TBM hydraulic system to obtain power, to drill the rock mass by an alloy bit through rotation and translation thereof. The drill-attitude control assembly controls an angle, a direction and a position of a drill rod and maintains drilling accuracy and stability. The data monitoring assembly acquires and stores a drilling dynamic-response signal by a high-accuracy sensor and a data recorder, to analyze an intactness characteristic of the rock mass. The TBM-platform fixing seat mounts the drilling device on the TBM.

摘要： An advanced monitoring device and an implementation method for a whole-process deformation curve of a surrounding rock during tunnel excavation is disclosed, comprising a steel pipe elastic body, a cathetometer structure and an embedded optical fiber, and an implementation step; the cathetometer is an equidistant series structure, and fixed in the steel pipe; the embedded optical fiber is encapsulated in the surface slot of the steel pipe; the cathetometer and the embedded optical fiber and the steel pipe form a deformation coordination structure, and the deformation of the surrounding rock can be deduced by calculating the variation of the cathetometer and the deformation of the optical fiber. The invention can test and calculate the deformation curve of the surrounding rock in front of the excavation face during tunnel excavation, and provide support for engineering dynamic design, construction and safety.
