Vehicle-mounted tunnel geological sketch device and application method thereof

Abstract

The invention provides a vehicle-mounted tunnel geological sketch device and an application method thereof. The vehicle-mounted tunnel geological sketch device comprises a data acquisition unit, wherein the data acquisition unit is arranged on a rail car in a tunnel and comprises shooting and scanning equipment, laser scanning distance-measurement equipment and infrared thermal-induction scanningequipment, the shooting and scanning equipment is arranged at two sides of the rail car and is configured to acquire an inner hole wall image of the tunnel, the shooting and scanning equipment at a single side covers the whole side wall from a vault intermediate line to one corresponding side, the laser scanning distance-measurement equipment is used for acquiring a distance from the laser scanning distance-measurement equipment to a tunnel wall, the infrared thermal-induction equipment is used for acquiring a temperature of a tunnel wall stratum, the data acquisition unit is used for transmitting the temperature to a data analysis system by a wireless transmission system, and the data analysis system is configured to analyze joint position and size and positions and sizes of a collapse cavity region and a block falling region according to a distance, acquired by the laser distance-measurement equipment, from the rail car to the tunnel wall, provide the whole three-dimensional space diagram of a tunnel, identify tunnel lithology by a trained model according to image characteristic and judge basic lithology of the stratum in the image.

Description

technical field [0001] The disclosure belongs to the field of geological map sketching, and relates to a vehicle-mounted tunnel geological sketching device and a using method. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] Before the official construction of the tunnel, the design unit needs to conduct a detailed survey of the hydrological and geological conditions in the area where the tunnel is located, and provide a detailed hydrological and geological report (including groundwater conditions, strata, lithology, structural zones, etc.), which will provide support for the later tunnel construction. Excavation provides guidance. At present, in the preliminary exploration process, geophysical exploration and drilling are mostly used to explore the underground geological conditions. Although this is the most scientific and widely used me...

AI Technical Summary

Problems solved by technology

At present, in the preliminary exploration process, geophysical exploration and drilling are mostly used to explore the underground geological conditions. Although this is the most scientific and widely used method at present, it still cannot fully grasp the underground geological and hydrological conditions. Therefore, after tunnel excavation, It is necessary to further observe and describe the geological conditions of the excavated section in detail. Through comparative research with the previous exploration data, the accuracy of the later tunnel construction can be continuous
