3D Imaging Tunnel Geological Advanced Forecasting Instrument and Forecasting Method

Abstract

The invention provides a three-dimensional imaging tunnel geological advance forecaster and a forecasting method, including: a host control terminal, a master station, a collection station, and a trigger station; the master station, as a management unit of the station, communicates with the collection station, the trigger station, and the host through wireless WiFi The control terminal communicates and transmits the sampling data, and manages the trigger time synchronization of the trigger station and the collection station through wireless communication. The power management unit of the master station includes a charging and discharging management module, a fuel gauge and a lithium-ion battery. The advantages are: all data interactions are transmitted wirelessly. Compared with the traditional wired data acquisition system that requires a large number of cables and difficult on-site wiring, this equipment does not require a large number of cables, and is easy to install, small and portable, and simple on-site layout. The error range of the synchronous sampling time of multiple collectors is 1-3 sampling points, which meets the time accuracy requirements of the tunnel geological advanced forecaster.

Description

technical field [0001] The invention belongs to the technical field of tunnel geological advance forecasting, and in particular relates to a three-dimensional imaging tunnel geological advance forecasting instrument and a forecasting method. Background technique [0002] Accompanied by the construction of a large number of tunnel projects, geological advance forecast, as an important link in tunnel construction, is playing an increasingly important role. The advanced prediction technology of tunnel geology can understand the geological conditions of the tunnel surrounding rock in advance in terms of time and distance, so as to provide reliable guidance for subsequent construction, reduce the blindness of construction, and reduce the risk of construction. The elastic wave method is currently one of the most commonly used and most effective methods for tunnel geological advance prediction. It can more accurately predict the geological conditions in front of the working face, a...
