Abstract

The invention discloses a rock wear resistance digital drilling test system. The rock wear resistance digital drilling test system comprises a digital drilling device for drilling a hole in a rock tobe tested, a rock fixing device, a rotating device, a digital sensor arranged on the digital drilling device and a rack. The digital drilling device is mounted at the upper part of the rack. The rockfixing device is mounted at the lower part of the rack and is aligned with the digital drilling device. The rotating device is installed below the rock fixing device so that the rotating device can drive rock fixed to the rock fixing device to rotate when working. The invention also relates to a rock wear resistance digital drilling test method. By monitoring the digital response information of the drilling tool, the unit drilling displacement in the rock drilling process is obtained and used for evaluating the abrasion resistance of rocks of different qualities, so that the hard rock tunnel boring machine is guided to reasonably select hob parameters, the construction efficiency is improved, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of tunnels and underground engineering, in particular to a digital drilling test system and method for rock wear resistance of different qualities. Background technique [0002] The safe and rapid excavation of the full-face tunnel boring machine (TBM) is gradually becoming a frontier hot issue in the field of tunnel engineering. During the TBM construction of hard rock tunnel engineering, the hob will be damaged due to the reaction of the rock. The life of the hob and the tunneling efficiency often depend on the in rock wear resistance. Engineering experience shows that in the case of mastering the rock wear resistance, setting the hob stiffness reasonably and optimizing the hob spacing will greatly increase the life of the TBM hob. Moreover, TBM construction prediction models usually take rock wear resistance as an important parameter. Therefore, pre-evaluating rock wear resistance is of great significan...
