Next, a processing operation for creating pipe line data such as a pipe division drawing and a pipe division table by the multi-thread pipe line designing device having the above configuration will be described.

FIG. 2 shows an example of the pipeline planning drawing which is the basis of the data input by the data input unit 1.

This pipeline design drawing exemplarily shows one relay point to the next relay point of the whole. However, between the relay points, a part of two straight pipe sections, which will be described later, is omitted.

In the drawing, what is linearly shown at the uppermost part is a plan view of the pipe line 23, and a portion partially shown by a curve is rightward or left when viewed in plan. It shows that it is curved by that angle in the direction. Therefore, after bending, it is originally necessary to draw the conduit continuously from the end point after the bending, but in this drawing, the conduit is shown as a straight line for the sake of drawing.

Further, what is shown in the central portion of the drawing is a vertical cross-sectional view of the pipe line 23 (a cross-sectional view taken along the arrangement direction of the pipe line) from the manhole 21 which is one relay point to the next. Pipeline 23 arranged up to the manhole 22 which is a relay point
Is shown. Then, consecutive numbers (No33 to No54) are given as ward points to each of the vertical cross-sectional views, and as a general rule, the distance between the ward points (hereinafter,
It is called a single distance. ) Is used as a standard to create pipe division data. The reference numeral 20 in the drawing indicates the level of the ground.

Below the longitudinal sectional view of the pipeline, the pipeline 23
The horizontal cross-sectional view (cross section orthogonal to the direction in which the conduit is arranged) is shown at two locations. In this embodiment, the number of pipelines 23 is four (23a to 23d). From the drawing, ward point No.
The pipelines 23a to 23d arranged in a horizontal row between 47 and the division point No. 48 are arranged in two rows and two stages between the division point No. 52 and the division point No. 53. This is the section where the ward point No. 51 will be described later, and each pipeline 23a is in this section.
It is shown that the arrangement of 23d is changed from the horizontal example to two rows and two stages. Regarding the numerical values entered below, EL indicates the planned transmission line height, and small letter l indicates the distance of the section.

Further, in the lower part of this drawing, a list of numerical values shown in FIG. 3 is shown along a vertical sectional view of the central portion. However, in this embodiment, due to the relation of drawing, FIG. 2 and FIG.
It is shown divided into and.

Each numerical value shown in this list indicates the planned height of the transmission line, the height of the pipeline, the ground height, the additional distance (cumulative distance from the starting point), the single distance, the measuring point, and the curve from the top. There is. Here, Nos given at fixed distances in the field of measurement points are measurement division points, and the distance between the division points is usually set to 20 m. Next, based on the above-mentioned pipeline design drawing,
A processing procedure for creating pipeline data will be described.

The operator inputs necessary data from the data input unit 1 using the input sheet shown in FIG. 4 in order to input each data of the above-mentioned pipeline design drawing. However,
Exemplarily shows one relay point (No4: corresponding to manhole 21 in FIG. 2) to the next relay point (No5: corresponding to manhole 22 in FIG. 2). ing.

In the figure, in the condition setting field 31, the condition shown on the right side of the condition is numerically selected and input. In the present embodiment, "2,2,2,2,3,1" is set from the top, and the next "0.5" is set to the condition "3" in the fifth condition setting from the top. (That is, Bellmouth (B
Since the condition that M) is used is set), the length is set to 0.5 m. Further, the next "2.5" and "1.5" respectively set specific angles.

When the setting of the condition setting column 31 is completed in this way, the process moves to the data input in the lower stage. First, enter the manhole number in the Manhole No. (MHNo) field. In this embodiment, No. 4 which is No. of the manhole 21 shown in FIG.
And fill in. Next, each ward point is input in the ward point column. This ward point No. is automatically input in sequence after the ward point of the starting section is input. Next, enter No. 5 of the manhole 22. In this example,
It is assumed that No33 to No54 are input as No. Also, at this time, in the manhole width (MH width) column,
Enter the width of the manhole.

Next, a single distance is entered in the single distance field. Here, for the short distance, the division point No 33 is set to 0.000 and the distance between the division points is input. Next, regarding the measurement point field, since the setting of the condition setting field 31 is short distance “2”, in this case, the measurement point number of the starting point and the distance from the measurement point are input. As a result, the station number and the station distance are automatically entered.

Next, the additional distance (cumulative distance from the starting point of the entire pipeline) is entered in the additional distance field. In this case, since the condition setting field 31 is set to the single distance “2”, the short distance additional distance is automatically input. In addition, the ground height column and the soil cover column are not entered because the setting of the condition setting column 31 is the pipe top height "2", and the pipe top height of each ward point is input in the next pipe top height column. .

Next, when there is a plane bend at an arbitrary division point,
Enter RNo, mR, and bend angle in the plane bend field. In this embodiment, the curvature can be used up to 200 mR. Also,
The display of mR is -mR if it turns left when viewed from the previous ward point.
Enter. For example, when mR is -5.0, a left bend of 5 mR is shown, and when mR is 5.0, a right bend of 5 mR is shown. Since the angle is necessary for drawing, enter the degree (degree).

Next, in the column for the number of holes, the number of holes required for the beginning of the pipeline and the changing portion is entered. Further, in the vertical section S column, "1" is input at a position where the vertical displacement is to be processed by the S curve. However, if the vertical angle is within the allowable range set in the condition setting field 31, the process is not performed. Also, in the flexible section column, enter "1" only when using a flexible joint. In addition, enter No in the pipe collapse section in the pipe collapse section. This No. is a continuous No. from the starting point, and in this embodiment, the pipe collapse No. 5 is input to the division point No. 37.

Next, in the combination pattern / temporary division point column, the combination pattern No. and provisional division (C1 to C
4) and the temporary division point (No 40, 42, 44, 46) are input. The provisional division points are input according to the rules therefor so that they can be processed by the composite section division data creation unit 6 described later. In this case, the temporary ward points (No40, 42, 4
For the single distance of 4, 46), enter 0.000 and do not enter the pipe top height.

With the above, the data input by the input sheet is completed.

The pipe division data creating section 2 fills in the necessary numerical values in the necessary items of the pipe division tables shown in FIGS. 5 and 6 based on the numerical data thus input from the pipeline design drawing.

That is, the manhole (MH) No, ward point, and manhole (MH) width columns are automatically copied from the input sheet, and the measurement point column is automatically determined in consideration of the measurement point intervals on the input sheet. calculate. In the survey distance column, the survey extension is automatically calculated, and in the pipe height column, it is automatically copied from the input sheet.

As for the inlet direction column, since the condition setting column 31 is set to "not reverse at intermediate joint (BM tolerance)", the inlet of the pipe faces right (-<) or left. (>-) Is judged and displayed. As a general rule, the direction of the socket shall be rightward from the starting point toward the piping direction. Therefore, in the receiving direction column, all facing right (-<) is displayed. In the middle joint column, 1 is automatically displayed at the last division point between manholes. The propulsion / vertical shaft column and the hole number column are automatically copied from the input sheet.

In the section type column, the section type is automatically determined from the information on the input sheet. In addition, the pipe collapse No. is automatically copied from the input sheet, and the flat bend / large bend columns are automatically copied with RNo, mR, and angle from the input sheet.

On the other hand, in the straight pipe section pipe division data creating section 3, since the sections indicated by the division points No. 34, 36, 41, 47, 50, 54 are straight pipe sections, the target pipes of these straight pipe sections are set. Automatic pipe division is performed using the path length.

That is, since the target pipeline length of the straight pipe section immediately after the starting point indicated by the division point No. 34 is 1.5 m, in this case, one 0.5 m bell mouth (BM) and 1 m straight pipe are used. One and are used to construct the section. Also, the ward point
Since the target pipeline length of the straight pipe section indicated by No. 47 is 10.0 m, in this case, 2 1 m straight pipes and 2 m straight pipes 4
Combine with a book (eg 1m straight pipe, 2m straight pipe, 2
Connect m straight pipe, 2m straight pipe, 2m straight pipe, 1m straight pipe in this order. ), Which constitutes the section. Moreover, since the target pipeline length of the straight pipe section indicated by the ward point No. 50 is 80.0 m, in this case, two 1 m straight pipes, three 2 m straight pipes and four 4 m straight pipes are combined. (For example, 1 m straight pipe, 2 m straight pipe × 2, 4 m straight pipe × 18, 2 m straight pipe, 1 m straight pipe are connected in this order.), And the section is configured. In addition, ward point No5
The target pipeline length of the straight pipe section immediately before the end point indicated by 4 is 32.
Since it is 5m, in this case two 1m straight pipes and 2m
3 straight pipes and 6m straight pipes and 0.5m bell mouth (B
M) in combination with one (for example, 1 m straight pipe, 2 m straight pipe x 2,4 m straight pipe x 6, 2 m straight pipe, 1 m straight pipe, 0.5 m
Connect them in the order of Bell Mouse (BM). ), Which constitutes the section.

In this way, the numerical values of the pipe division data of each straight pipe section obtained by the calculation in the straight pipe section pipe division data creating unit 3 are sequentially entered in the pipe division table shown in FIG.

In the plane bend section division data creating section 4,
Since the sections indicated by the ward points No. 42 and 45 are plane curved sections, automatic pipe division is performed using the curvature of each plane curved section and the surveying single distance. When using a 2m pipe in a flat bend section, divide the pipe according to the rule that the surveying single distance is 3m or more, and connect 1m R pipe at each end or 1m R pipe at the back. To do.

That is, since both the division point No. 42 and the section No. 45 have a single distance of 6.0 m and a curvature (mR) of 10.0 m in the plane bending section shown, in this case, 1 m of 10 mR These sections are configured by combining two tubes and two 2 m 10 mR tubes (for example, connecting 1 m 10 mR tube, 2 m 10 mR tube × 2, 1 m 10 mR tube in this order). However, when there are multiple combinations, 3 of them
Approximately 4 cases are displayed on the screen and can be input by operator's selection.

In this way, the numerical values of the pipe division data of each plane bend section calculated by the plane bend section pipe division data creating unit 4 are sequentially entered in the pipe division tables shown in FIGS. 5 and 6. .

Although not shown in this embodiment, in the large bend section of 40 mR to 120 mR in the plane bend section, the pattern is selected based on the large curvature conduit type selection table (not shown). For curvatures that are not entered in the selection table, pipe division data shall be created in principle according to the following rules. In other words, the curvature that is not entered in the selection table is the same as the curvature immediately after that, and is automatically divided from the surveyed single distance. As for the pipeline structure, in principle, the number of straight pipes used / 2 + the number of curved pipes used + the remaining straight pipes is used, and this pattern is repeated. In addition, both straight and curved pipes are 1
The m pipe shall be used, and when there is a fraction, a 1 m straight pipe shall be connected behind.

FIG. 7 shows an example in which a plurality of large bend pipe division patterns are displayed according to such a rule. In this example, as a combination when the curvature (mR) is 40.00 and the single distance (m) is 10.50,
It displays the pattern of the type. That is, the number 1 is
When constructing by connecting 11 m straight pipes while bending them little by little, the number 2 is a combination of 1 m straight pipe and 1 m 20 mR pipe repeated 5 times to connect, and finally 1 m straight pipe 1 When connecting and constructing a book, the number 3 is 1m straight pipe 1
When the combination of a book, two 20mR tubes of 1m and one 1m straight tube is repeatedly connected twice, and finally three 1m straight tubes are connected, the number 4 is one 1m straight tube. 1m 2
It shows a case where a combination of three 0 mR tubes and two 1 m straight tubes is repeatedly connected once, and finally five 1 m straight tubes are connected. The operator will select and input one of the four displayed patterns.

In the vertical section division data creation section 5,
Since the sections indicated by Nos. 35, 38 and 39 are vertical sections, the vertical section angle is obtained from the difference in the height of the pipe tops of these vertical sections. If the obtained vertical section angle is larger than the allowable vertical section angle set in the condition setting field 31, the R pipe is automatically selected using the following equation.

[0070]

## EQU1 ## R = 180 × nL / πθ (1) where nL is the length of the curved tube.

Here, when the R tube of 2 m is used, the configuration of the R tube is one R tube of 1 m at each end or 1 m behind.
Connect one R tube of. In addition, pipe division is performed according to a rule such as automatic straight pipe division for the front straight portion.

That is, since the vertical angle of the vertical section indicated by the division point No. 35 is 2.63 degrees and the single distance is 9.5 m, in this case, in this embodiment, one 1 m straight pipe and 2 m straight pipe 4 are used.
Combine a book with a 1m 20mR tube (for example,
Connect 1m straight pipe, 2m straight pipe × 4, 1m 20mR pipe in this order. ), Which constitutes the section. In addition, ward point No38
The vertical angle of the vertical section indicated by is 2.6 degrees and the unit distance is 1
Since it is 3.5 m, in this case, 1 m in this embodiment.
Combining one straight pipe, six 2m straight pipes and one 1m 20mR pipe (for example, connecting 1m straight pipe, 2m straight pipe × 6, 1m 20mR pipe in this order), the section. Constitute. In addition, since the longitudinal angle of the longitudinal section indicated by the ward point No. 39 is 3.1 degrees and the single distance is 50.0 m, in this case, in this embodiment, 1 m straight pipe and 2 m straight pipe and 4 m A combination of 10 straight pipes and one 1m 20mR pipe (for example, 1m straight pipe, 2m straight pipe × 2,4m straight pipe × 10, 2m
Straight pipe x 2, 1m 20mR pipes are connected in this order. ),
Configure the section. However, when there are a plurality of combination patterns, about 3 to 4 examples of them are displayed on the screen and can be input by the operator's selection.

FIG. 8 shows an example in which a plurality of pipe division patterns are displayed according to the rule of the vertical section. In this example, the vertical angle is 4.236 and the single distance is 20.
As a combination in the case of 000, three types of patterns are displayed. That is, number 1 is 1m, 15m
If it consists of only one R tube, the number 2 is 2m, 25m
If it is composed of only one R tube, the number 3 is 1m 25m
The case where two R tubes are connected is shown. The operator selects and inputs one of the three displayed patterns.

In this way, the numerical values of the division data of each vertical section, which are calculated by the vertical section division data creating unit 5, are sequentially entered in the division table shown in FIG.

Although it does not appear in this embodiment, in the longitudinal section S of the longitudinal section (section that bends in the so-called S shape), from the single distance, the difference between the pipe height and the longitudinal angle, The R pipe and the straight pipe are automatically selected using the above (1) and the following equation (2).

[0076]

## EQU00002 ## Remaining straight pipe distance = target pipe length-2nL (2) Here, the pipe line configuration is limited to the R pipe, the straight pipe, and the R pipe, and the two front and rear R pipes have exactly the same configuration. And Further, when the R tube of 2 m is used, the configuration of the R tube is such that one R tube of 1 m is connected to both ends or one R tube of 1 m is connected to the back. In addition, pipe division is performed according to a rule such as automatic straight pipe division for the front straight portion.

If there are several patterns when selecting the R tube, about 3 to 4 examples of them are displayed on the screen as in FIG. 8 and can be input by the operator's selection.

In the composite section pipe division data creating section 6,
Since the sections indicated by Nos. 43 and 44 are composite sections, automatic pipe division is performed using the curvature of each of these composite sections and the vertical angle obtained from the difference between the surveying single distance and the pipe top height.

Here, the patterns to be combined are limited to the three patterns shown in FIGS. 9 to 11 in this embodiment. That is, when the vertical bending point is within the plane bending section as shown in FIG. 9 (the four ranges indicated by the broken lines on the right side of the combined piping range in this case are set). As shown in 10, when the vertical bending point is the same as the start point or the end point of the plane bending (in this case, the two ranges surrounded by broken lines are set on the right side of the combined piping range). As shown in FIG. 11, when the vertical bending point is outside the flat bending section and the processing bending pipe enters and exceeds the flat bending pipe (as a synthetic piping range in this case, surrounded by a broken line on the right side thereof) Indicated 2
Set two ranges. ) Are three patterns.

9 to 11, C1 to C4 are input as temporary division points. Further, the type and range of the combined piping range can be selected and input from the menu. Then, based on that value, the R pipe is displayed when the synthetic angle and piping are possible,
The operator selects and inputs from the display. After this,
Necessary temporary ward points are converted into main ward points, and unnecessary temporary ward points are deleted.

That is, since the composite angle of the composite section indicated by the division point No. 43 is 12.0 degrees and the single distance is 1.0 m, in this case, one 1 m 10 mR tube is used. , Compose the section. In addition, the synthetic angle of the synthetic section indicated by the division point No44 is 12.0 degrees, and the single distance is 1.0 m.
Therefore, in this case also, in this example, 10
The section is constructed using one mR tube.

In this way, all the numerical values of the pipe division data created by the pipe division data creation units 3 to 6 are entered in the pipe division table shown in FIG. It is stored as a pipe data file.

The section indicated by the ward points Nos. 37 and 51 is a pipe collapse section, but the pipe division table shown in FIG. 4 indicates that the section is a pipe collapse section (this No. is for all pipelines). Only consecutive numbers from the starting point).

Next, the processing operation for creating pipe division data for this pipe collapse section will be described.

FIG. 12 shows a pipe collapse table, and FIG. 13 shows pipe division data and a material summary table for the pipe collapse section.

In the pipe-breaking section pipe-dividing data creating section 7, since the sections indicated by the division points Nos. 37 and 51 are pipe-breaking sections, each pipeline in each of these pipe-breaking sections (in this embodiment, four pipes 23a- 23d), each value of the actual processing length, the pipeline direction and the inclination angle versus the X axis (inclination angle with respect to the X axis) is calculated.

In FIG. 11, each of the pipelines 23a-23d is No1.
It is represented by ~ 4. Then, for each pipeline No., the pipeline position before the displacement and the pipeline position after the displacement are input by the XY coordinate display. Further, the planned displacement distance is input as horizontal (X coordinate) and vertical (Y coordinate) for each pipeline No.

The pipe-breaking section pipe division data creation unit 7 obtains the total (Z) in the planned displacement distance column based on these input data, and also the total (Z ') and difference (Z) in the actual processing length column. -Z ') and processing distance (L) are numerically calculated for each item. Then, the pipeline direction of each pipeline obtained as a result is indicated by an arrow and the inclination angle with respect to the X axis is entered. However, with respect to the pipe line direction, the direction when viewed in a cross section (direction orthogonal to the pipe line arrangement direction) is shown.

Each of the pipelines (No. 1 to No. 1) thus obtained
Based on the numerical data of 4), pipe division data creation processing is performed in each pipe division data creation unit 3 to 6 for each pipeline as needed, and the result is entered in each column of FIG. In addition, the total of the pipe types used for each pipeline is entered in the material totaling column, and the total number of pipes for each pipe type is entered in the bottom row.

In this way, the pipe breaking data shown in FIG. 12 and the pipe dividing data and material summary table shown in FIG. All numerical values are entered, and pipe division data storage unit 9
It is stored as a data destruction file in.

Further, in the pipe division data storage unit 9, FIG.
The material summary table shown in is stored as a material summary file. This material totaling file is data in which the pipe allocation table shown in FIG. 5 and the pipe allocation data shown in FIG. 13 and the pipe types used in the material totalization table are totaled for each ward point (No33 to No54). .

By the above processing, all the pipe division data can be obtained. Therefore, the site worker looks at the pipe allocation table shown in FIGS. 5 and 6 and the pipe allocation table of the pipe collapse section shown in FIG. It is possible to perform the piping in accordance with the pipeline plan drawing only by sequentially performing the piping work using the number and the number.

When a drawing for supplementing such a pipe allocation table is required, the output unit 11 receives a drawing instruction from a keyboard (not shown) or the like, and the output of the output unit 11 is shown in FIGS.
Create and output the pipe division drawing and pipe collapse drawing shown in.
The splitting drawings shown in FIGS. 15 and 16 correspond to the numerical data of the splitting tables shown in FIGS. 5 and 6, and the pipe collapse drawings shown in FIGS. 17 and 18 are the splitting data shown in FIG. It also corresponds to the numerical data of the material summary table. It should be noted that, in FIG. 15 and FIG. 16, overlapping sections are shown to make the connection relationship between the two drawings easy to understand. Further, FIG. 17 shows a plan view on the upper side and a vertical sectional view on the lower side.
