Abstract

The invention discloses a microseismic monitoring device equipped with an embedded TBM, which comprises a support shoe arranged on a TBM main body, a microseismic module at the support shoe is arranged on the support shoe, an annular slide rail is set on the TBM main machine, and a fixed end of a horizontal oil cylinder Set on the TBM host, the telescopic end of the horizontal cylinder is connected to the circular slide rail, the circular slide rail is connected to the fixed end of the tensioning cylinder, and the telescopic end of the tensioning cylinder is connected to the microseismic module at the shotcrete bridge through a hydraulic damper. The invention can realize continuous microseismic monitoring in the whole process of TBM, and can advance the monitoring interval synchronously following TBM excavation to ensure the accuracy of monitoring results, avoid frequent drilling, installation and disassembly of sensors in traditional drilling monitoring, and reduce loss The efficiency greatly reduces equipment cost and labor cost.

Description

technical field [0001] The invention relates to the field of microseismic monitoring, and more particularly relates to a microseismic monitoring device equipped with an embedded TBM. Background technique [0002] With the continuous improvement of mechanical manufacturing level, tunnel engineering construction is gradually developing towards mechanization and modularization. As a highly integrated mechanized tunnel construction equipment, TBM has the characteristics of fast excavation speed and high safety, and has been widely used in various rock tunnel constructions. [0003] Rockburst is one of the main problems encountered during TBM excavation. For tunnel projects with poor rock quality, well-developed joints and fissures in the rock strata, or large buried depths and high stress, rock bursts are prone to occur when the rock mass is disturbed by excavation, causing TBM jamming, equipment damage, and even major personnel and property losses. Microseismic monitoring has...
