An Intelligent Positioning and Measuring Method for the Excavation Line of Tunnel Face

Abstract

The invention relates to a method for intelligently positioning and measuring an excavation line of a tunnel face. Intelligent positioning and measurement of the excavation line of the tunnel face arecompleted through interaction of a total station connected by a data communication module and a computer installed with a tunnel section measuring and setting system; the total station consists of anelectronic angle measuring device, an electronic distance measuring device, a calculation and storage module, a motor driving device and an ATR module capable of automatically searching a prism center, and is installed on the computer through C++ language development-based tunnel section measuring and setting system software; the tunnel section measuring and setting system software is operated toinput data; the corresponding relation between line mileage in the line as well as line plane coordinates and altitude data in the line is generated; the three-dimensional coordinate information of adesign point on the excavation line of the tunnel face to be set out is transmitted to the total station through the data communication module; and the total station completes the setting-out task ofthe tunnel face, so that the tunnel excavation line can be positioned and measured rapidly and accurately, operation is simple and the intelligent degree is high.

Description

technical field [0001] The invention relates to the field of tunnel construction, in particular to an intelligent positioning and measuring method for an excavation line of a tunnel face. Background technique [0002] With the development of social economy and the improvement of engineering design level, in the fields of transportation, water conservancy, national defense and other fields, the architectural structure of the tunnel has been widely adopted. When excavating the tunnel, it is necessary to determine the tunnel face, the tunnel face The face refers to the working face where the excavation tunnel is constantly moving forward, to be precise, it is facing the working face that the construction workers are constantly moving forward. The quality of the excavation line at the tunnel face is directly related to the quality and Efficiency. Existing methods for setting out the excavation line of the tunnel face include the center line method, the five-inch platform method,...

[0002] With the development of social economy and the improvement of engineering design level, in the fields of transportation, water conservancy, national defense and other fields, the architectural structure of the tunnel has been widely adopted. When excavating the tunnel, it is necessary to determine the tunnel face, the tunnel face The face refers to the working face where the excavation tunnel is constantly moving forward, to be precise, it is facing the working face that the construction workers are constantly moving forward. The quality of the excavation line at the tunnel face is directly related to the quality and Efficiency. Existing methods for setting out the excavation line of the tunnel face include the center line method, the five-inch platform method, and the method of first determining the section and then drawing the arc. Due to the influence of the up and down not being perpendicular to the horizontal plane, it is impossible to set out the line accurately and quickly. The method of setting out the excavation line on the face of the tunnel shows the disadvantages of long time consumption and low efficiency.
