Problems solved by technology

At present, the detection method is the "inverted level gauge method", which has relatively high accuracy, but the operation is relatively cumbersome, and parts need to be embedded on the top of the tunnel; the tunnel is generally dark, which affects the reading accuracy of the level gauge; the muck is excavated in the tunnel The process will cause each other's work to be delayed, and this method is time-consuming and laborious

Description

technical field [0001] The invention belongs to the technical field of measurement, and in particular relates to a tunnel settlement convergence detector and a detection method thereof. The rapid detection of tunnel settlement convergence is realized through the combined application of a laser interference ranging device and a gravity sensing device. Background technique [0002] Tunnel clearance is a very key control factor in tunnel construction. In excavation control, the size of tunnel clearance affects the amount of excess and underexcavation, and also has a great impact on the thickness of the secondary lining in the future; directly in the secondary lining It is related to whether the cross-sectional clearance of the formed tunnel is violated. Therefore, the settlement convergence of the tunnel is an essential inspection, which can make a judgment on the stability of the tunnel, give an early warning of unsafe factors in the tunnel, and prevent accidents. At present,...
