Compared with prior art, the beneficial effects of the invention are as follows：It is originally and geodetic coordinates is collected by live total powerstation, so
Then and design comparison out break on machine plotting to computer, then is seen according to coordinate by Hou Hui offices.Now by in-site measurement,
Out break is calculated by calculator at once as a result, achieving the purpose that the out break for solving the problems, such as scene in time.
Specific implementation mode
This method is applied on 4850 calculator of Casio 4800 or Casio, main to consider that being applied to power station presses
Construction lofting (setting-out of peripheral position when penstock is installed) before the excavation of hydraulic piping inclined shaft part, periphery has been excavated later
It backbreaks or owes to dig and check and processing measures, when use must be with mileage for x, and line width is the construction coordinate system of y.
In the methods of the invention, N=0 then inputs known date；N ≠ 0 carries out Setting-out procedures input.
Given data X0(S ＞ 0 (above flat section), Z ＜ 0 (straightway), X ＞ 0 (lower flat section)), survey station point x coordinate (unit
Rice) (Fixed Initial Point), lower horizontal section setting-out is carried out for timing, straight pipe setting-out is carried out when being negative.
(Fixed Initial Point pile No. (pressure pipeline mileage (unit rice) at point of contact), H (QIE, DIAN) (are started K0 (QIE, DIAN)
Select center of circle elevation (unit rice)).
Bend pipe central angle (using 10 system of radian) on A (s ＞ 0, z ＜ 0, x ＜ 0), the angles A are timing, carry out bend pipe and put
Sample "≤", upper flat section longitudinal slope angle value, descending is negative, go up a slope for it is positive (must be 10 system of decimal, cannot use ° ' ")；When the angles A are negative
Carry out lower bend pipe, straight pipe setting-out (angle value at this moment is the longitudinal slope angle of inclined shaft straight pipe).
The X-coordinate (unit rice) of construction coordinate system at the point of contact X (QIE.DIAN)；KZ (ZONG.DIAN) carries out straight pipe and puts
Termination mileage when sample；R is pressure pipeline radius (m)；L is upper bend loss or lower bend loss radius；X, Y is that layout point construction is sat
Mark system (i.e. Measured Coordinates)；H is setting-out point height (actual measurement point height)；K0+ is layout point mileage (eyeball mileage pile No.)；
QIAN.WA is to owe to dig, and CAO.WA is to backbreak；＜=or=＞ is the left and right movement value in direction；Lm moves up for D in center pile No. dynamic
It is flat away from；H^ or hv is that elevation moves up and down value, plagioclase data of the layout point to center of circle when excavation.
Note that the uniformity of each portion's coordinate of inclined shaft, it is necessary to be converted into unified coordinate system and carry out setting-out work.(1) vertical disconnected
Since the mileage of inclined shaft is with bend pipe curve on face, straight tube grade line is incremented by, and to be plane be construction coordinate system
System.Must carry out conversion to each other can use program；(2) when being converted, it is necessary to by straight pipe, lower horizontal section point of contact in
Journey is converted into the point of contact construction coordinate system internal coordinate i.e. x (QIE, DIAN).
Setting-out inclined shaft program editing inputs, it is necessary to be inputted according to these symbols on 4800 or 4850 calculators, symbol is not
Can be different, include the following steps：
Step 1, when meeting condition N equal to zero, need to input given data O, Q, Z, RB.Know that starting point pile No. is sat
Mark, starting point point of contact pile No. data, terminal point of contact pile No. data, and if meet starting point pile No. more than zero, it is also necessary to it inputs curved
The radius in road, then inputs white triangle, and expression carries out judging whether to meet condition；If meeting condition, continue to input inclined shaft
The angle oblique angle A, A is just to be more than zero, releases and arrives E, carries out the program of bend pipe, then inputs white triangle and is indicating to be judged whether
Meet condition.
If step 2 is unsatisfactory for N=0 in step 1, carry out lower bend pipe and straight pipe setting-out less than zero, input straight pipe or
Lower horizontal section starting point point of contact data.After inputting white triangle and indicating to judge to determine, into next step.
Step 3 allows C to be equal to absolute value A (angle value is just better to carry out latter step calculating and input), and u is equal to radius, needle
Three variables of measurement are framed with { }, can be repeatedly input, with POL (), (it is polar that pol indicates that known coordinate calculates
Formula), calculate quadrant angle, judge it is positive and negative, when angle is less than zero, then azimuth add 360 ° for positive value, the value cosine value and length
Product obtain the pile No. of the measurement point.
If step 4, O (O indicates the azimuth calculated) are less than zero, release azimuth J subtracts 90 ° and is subtracting inclination angle A
(imparted be equal to C characters after inclination angle A takes absolute value in front) while distance is multiplied by sine；U is equal to zero, obtains stake
Number (point of contact pile No. is multiplied by cosine azimuth plus distance).Input goto2 and white triangle indicate entry into the place of second calculating,
White triangle judges to enter calculating in next step after position is judged.
Step 5, A are more than zero, release azimuth and are equal to S-J；Azimuth is released if being unsatisfactory for A and being more than zero condition to be equal to
Then J-C inputs white triangle expression and needs to carry out judgement selection in this place.
If step 6, M are equal to azimuth J, and J is less than zero and adds 360 ° with regard to releasing azimuth, is calculated after judgement is suitable
W and J, M directly obtain J less than zero and become-J, and after inputting white triangle judgement, M also releases J if it is greater than 180 and is equal to-J；Then lead to
It crosses K=Q+2 π LJ ÷ 360 and pile No. K is calculated.A subtracts 180 equal to J more than zero release M and subtracts S simultaneously, if not just more than zero
Release M subtracts J equal to C and then white triangle input display is judged herein.K pile No. is more than starting point pile No. B and releases goto1 entrance
One step calculates, and white triangle expression will also judge herein.
Step 7, fix3 indicate to retain 3 decimals in display below, aobvious when K " ko+ " expressions calculating is to this
That show is K0Visual representation pile No., quotation marks indicate to need thing to be shown；The black triangle meaning is exactly after calculation is arrived here, to need to show
K (pile No.) is followed by white triangle and also has black triangle, indicate judge after meet condition after, calculate to need exist for show
Black triangle will be marked.
In this counterweight, O indicates that construction coordinate system internal coordinate, that is, point of contact x (QIE, DIAN), survey station point x coordinate are in step 1
Fixed Initial Point (unit rice) carries out lower horizontal section setting-out for timing, and straight pipe setting-out is carried out when being negative.Q is point of contact starting point pile No., Z
It is excavation construction pipeline turning radius data for point of contact starting point elevation, RB, abs is to indicate absolute value, and C is in program counter
C is exactly positive angle, and angle has positive and negative generally in mapping, and negative number representation direction of rotation is different, at the point of contact X (QIE.DIAN)
The X-coordinate (unit rice) of construction coordinate system.
