Three-dimensional imaging tunnel geological advance forecaster and forecasting method

Abstract

The invention provides a three-dimensional imaging tunnel geological advance forecaster and a forecasting method. The three-dimensional imaging tunnel geological advance forecaster comprises a host control terminal, a master station, an acquisition station and a triggering station; the master station is used as the management unit of a station, performs communication with the acquisition station, the triggering station and the host control terminal through wireless WiFi so as to transmit sampling data, and manages the triggering time of the triggering station and the acquisition state to be synchronous through a wireless communication manner; and a master station power management unit comprises a charging and discharging management module, a voltameter and a lithium ion battery. The three-dimensional imaging tunnel geological advance forecaster has the advantages that: all data interaction is carried out through wireless transmission, compared with the traditional wired data acquisition system needing a lot of cables and difficult in field wiring, the three-dimensional imaging tunnel geological advance forecaster does not need a lot of cables, and is convenient to install, small, portable and simple in field configuration; the synchronous sampling time error range of multiple acquirer is within 1-3 sampling points; and requirements of the tunnel geological advance forecaster on the time precision are satisfied.

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...
