Problems solved by technology

The triangulation method requires a lot of positioning parameters in the application, and it is very cumbersome and time-consuming in the calibration of the measuring equipment. If a certain parameter in the system cannot be accurately obtained during the actual measurement, it will cause errors in the measurement data
The measurement electronics are far more complex than the pulse method

Abstract

The invention discloses a simple type tunnel section instrument which comprises a horizontal base and a frame.A horizontal main transverse shaft capable of rotating around the central axis is arranged on the frame, a first main observation device is fixed onto the main transverse shaft, a shaft bracket is further fixed onto the main transverse shaft, an auxiliary shaft capable of rotating around the central axis is arranged on the shaft bracket, a first auxiliary observation device is fixed onto the auxiliary shaft, and a first main observation line and a first auxiliary observation line are positioned in the same plane; a main dial is mounted between corresponding positions of the main transverse shaft and the support, and an auxiliary dial is mounted between corresponding positions of the auxiliary shaft and the shaft bracket; the main transverse shaft and the auxiliary shaft can electrically rotate.The simple type tunnel section instrument has the advantages that the simple type tunnel section instrument can be directly used for measuring sections of tunnels without tedious time-consuming calibration in advance, influence of factors such as external temperatures on equipment can be reduced to a great extent, requirements on distance measurement precision can be completely met, and the simple type tunnel section instrument is convenient to operate.

Description

technical field [0001] The invention relates to a tunnel profiler. Background technique [0002] Excavation is a key process of tunnel construction period and cost. Over-excavation not only increases the project cost due to the increase of slag discharge and lining volume, but also directly affects the stability of surrounding rock due to stress concentration caused by local over-excavation. Under-excavation will directly affect the thickness of the lining and cause hidden dangers to the quality and safety of the project. Various data show that the control of overbreak and underbreak has an important influence on the reliability and economic benefits of the tunnel structure. Tunnel profilers are used for fast and accurate measurement of tunnel sections. Its core components are angle sensors and range finders. [0003] Ranging information plays an important role in tunnel section scanning. According to the principle of ranging, it can be divided into triangulation method,...
