Abstract
The invention discloses a simple method for measuring the height of a theodolite. A steel tape is used to lead out two rays from a measurement control point, and the two rays and the extending line of the collimation axis of the theodolite under a horizontal state form a planar triangle in space, and a universal bevel protractor is used to measure the included angle between the two rays, namely one interior angle value of one triangle. The length of rays (two edges of the triangle) can be read directly from the steel tape, and the length of each edge of the triangle and corresponding opposite angle can be calculated according to the cosine law, law of sines, and the Pythagoras theorem, and finally the height of the theodolite can be accurately calculated. The calculation principles are clear, the measurement precision is high, the equipment used is simple, and the operation is convenient and easy to grasp. The measurement efficiency is high, and the engineering utilization is convenient.
Description
Technical field
The invention belongs to engineering surveying and engineering application technical field, particularly to a kind of surveyor's transit height of instrument
Short-cut method.
Background technology
Theodolite used in engineering survey, instrument outer wall is labeled with a horizontal line, this horizontal line and instrument scale center
Level, the measurement of instrument height is the oblique distance directly marking horizontal line with tape measure control point on instrument mostly, then in basis
Experience and total powerstation volume size deduction certain numerical value（About 1.5 ~ 2.0cm）And obtain.The method is simple to operate, with extensive,
But measure error is big, and slant height measurement process artifical influence factor is larger.Not yet have so far a kind of simple to operate and
Reliable theodolite height of instrument measuring method.
Content of the invention
It is an object of the invention to provide a kind of short-cut method of surveyor's transit height of instrument, to overcome above-mentioned background skill
The problem proposing in art.
Concretely comprise the following steps：
(1) theodolite centering leveling have been set up according to the regulation of Code for engineering surveying at measurement control point.
(2) draw two rays with steel tape from measurement control point and intersect at different two from the collimation axis extended line of theodolite
Point, obtains the angle between two rays with universal protractor measurement.
Article (3) two, ray and the collimation axis extended line of theodolite surround a plane triangle in space, because ray is long
Degree can directly read from steel tape, can calculate each edge lengths of triangle and its diagonal according to the cosine law, sine
Angle.
(4) draw in the right angled triangle that ray surrounds in the vertical line of theodolite, collimation axis extended line, steel tape, utilize
Pythagorean theorem can accurately calculate the height of instrument of theodolite；Because draw two rays from measurement control point, so can
Calculate two height values of theodolite, take its mean value to be theodolite height of instrument.
(5) it is to improve certainty of measurement, repeat step (2) ~ (4) further, multigroup theodolite instrument height number of degrees can be obtained
Value, takes its mean value to be theodolite height of instrument.
Computing Principle of the present invention is clear, simple to operate understandable, and certainty of measurement is higher than slant height mensuration, and the geographical ring to measurement
Border no particular/special requirement；The precision of steel tape is higher, and the height of instrument that this method records is also higher.
