Problems solved by technology

At present, for the measurement of the convergence deformation of the surrounding rock, when the drill and blast method is used, the convergence meter, photoelectric range finder and other methods can be used; while when the TBM construction is used, the above method fails due to the lack of measurement space and effective measurement methods, resulting in At present, during TBM construction, there is basically no monitoring of the convergence deformation of the surrounding rock

Abstract

The invention discloses a monitoring system for deformation of TBM surrounding rock. The monitoring system for deformation of TBM surrounding rock includes: a displacement sensor, which is installed in the TBM shield shell to monitor the radial deformation data of surrounding rock and can radially expand against the shield shell; a data-collecting device, which is electrically connected with displacement sensor and is used t collect radial deformation data; a controller, which is electrically connected with the data-collecting device and is used to receive the radial deformation data collectedby the data-collecting device or controls the data-collecting device; and a data-processing device, which is used to process the radial deformation data, so as to the correspondent data information of a tunnel. The monitoring system for deformation of TBM surrounding rock can achieve the monitoring of the radial deformation of the surrounding rock and can provide prediction for people to avoid that the radial deformation of the surrounding rock is so large that a tunnel-boring machine might break down as a result of the surrounding rock's pressure on the shield shell.

Description

technical field [0001] The invention relates to the field of tunnel excavation construction, in particular to a monitoring system for surrounding rock deformation in TBM construction. Background technique [0002] Before the tunnel (tunnel) is excavated, the rock mass is in the initial equilibrium state; after the tunnel (tunnel) is excavated, due to the unloading of the excavation, the stress of the rock mass is adjusted, and the stress-strain state of each point around the tunnel changes, resulting in the formation of surrounding rock Convergent deformation. At present, for the measurement of the convergence deformation of the surrounding rock, when the drill and blast method is used, the convergence meter, photoelectric range finder and other methods can be used; while when the TBM construction is used, the above method fails due to the lack of measurement space and effective measurement methods, resulting in At present, during TBM construction, the convergence deformati...
