Description
Technical field
The present invention relates to tunnel cross-section instrument.
Background technology
Excavation is the critical process of constructing tunnel duration and cost, backbreaks not only due to go out the quantity of slag and lining cutting amount increases and improves construction costs, also can backbreak generation problem of stress concentration because local and directly affect surrounding rock stability.Owe to dig, directly affect lining thickness, hidden danger is produced for construction quality and safety.Various data show, out break controls that reliability and the economic benefit of tunnel structure are had material impact.Tunnel cross-section instrument is for quickly accurately measuring tunnel cross-section.Its core component is angular transducer and diastimeter.
Ranging information has important function in tunnel cross-section scans.According to range measurement principle, it is possible to be divided into trigonometry, impulse method, phase method.Trigonometry is that beam of laser is irradiated on object, and part diffuse-reflectance laser is through prism imaging on photoelectric detection equipment.Trigonometry has a lot of positional parameter requirement in application, very loaded down with trivial details and time-consuming on measurement device is demarcated, if a certain parameter cannot accurately obtain in system during actual measurement, will make measurement data generation error.When measurement device has small variations, in system, each parameter all must be demarcated again.See that perhaps the intelligence Sun Changku that admires writes, " 3D reverse-engineering " (China Measuring Press 2002 April the 1st edition) p16.
Consider the environment in tunnel, general inapplicable trigonometry.He Baoxi edits, and the Yellow River water conservancy publishing house publishes its " total station survey technology " chapter 2 second section in August, 2005, describes the range measurement principle of current total powerstation, mainly impulse method, ranging phase method, is required for the complicated electronic system of correspondence.Impulse method is found range, and the pulse that directly mensuration diastimeter sends comes and goes the time of tested distance.According to Ye Xiaoming, Ling Mozhu, publishing house of Wuhan University publishes it " total powerstation errors of principles " p8 in March, 2004, even if the clock frequency for timing has atomic little error, also results in very big measurement error.Such as clock frequency is 100MHz, even if there being ± the frequency error of 1Hz, range error is also up to ± 1.5m.So impulse method certainty of measurement is low, it is mainly used in long-range low measure of precision.Ranging phase method, its principle is that the phase place change produced by measuring continuous print modulation signal to come and go on testing distance carrys out the indirect determination propagation time, thus trying to achieve propagation distance.Ranging phase method, relate to control and the computing of complexity, such as survey chi conversion and control, light path converting control, dim light automatically controls, survey phase rhythm (sequencing contro), phase place distance transform, coarse-fine chi distance Linking operation etc. (see Ye Xiaoming, Ling Mozhu, publishing house of Wuhan University publishes it " total powerstation errors of principles " p15 in March, 2004).The electronic system measured is complicated more than impulse method.Thus can cause a lot of problem.Ye Xiaoming, Ling Mozhu, publishing house of Wuhan University publishes it " the total powerstation errors of principles " p42 the 3rd chapter in March, 2004 and has analyzed, same frequency photoelectricity in such as circuit harasses the circular error that signal causes, the error that inner quartz crystal oscillator temperature influence causes.Li Guangyun, Li Zongchun edit, and Mapping Press publishes it " industrial measuring system principle and application " p134 in January, 2011, also mentions actual range frequency and the inconsistent range error problem caused of design frequency.
Having a problem that range accuracy is most important, no matter pulse ranging or phase ranging, its range accuracy both depends on the accurate measurement to the light velocity in air.And in actual measurement process, the light velocity is subject to the situation impacts such as atmospheric temperature, humidity, air pressure, it is necessary to measure these meteorologic parameters in advance, and carry out the atmospheric correction being correlated with.Editing according to Li Zeqiu, publishing house of Wuhan University of Technology publishes it " total station survey technology " p22 in July, 2012, the atmospheric correction of total powerstation also with this total powerstation used by the find range wavelength of light wave relevant.
