A current state map, a road plan map, and the like are displayed. Thereafter, prior to drawing a pipe route for burying a telephone line, a power line, or the like as an underground line, that is, a pipeline indicating the route of the underground line, the keyboard 12 is operated to change the pipeline name. Input (S10). Thereafter, the user operates the mouse 14 to draw a conduit at an arbitrary position on the screen of the CRT 18 (S11). The pipeline at this time is drawn as a straight line or a curve by the operation of the operator. When the pipeline is drawn as a straight line, for example, as shown in FIG. 4, the section from the start point to the end point of the pipeline is divided into a plurality of measurement points, for example, at a pitch of 20 meters, and as information on the position of each point, A position on the map, that is, XY coordinates is generated as pipeline information. On the other hand, when a part of the pipeline is drawn as a curve, for example, as shown in FIG. 4 and No. No. 5 is a curved line. 4 and a straight line belonging to No. 4. An intersection (IP2) at which the straight line belonging to No. 5 intersects is determined, and curve specifications at this intersection are calculated. At this time, an arc tangent to each straight line is determined from the two straight lines and the input radius, and the center point, the start angle, the end angle are calculated from the obtained arcs, and the intersection angle, the tangent length, the arc length, and the outer line length are calculated. Is done. This allows

When the earth cover, the separation, the excavation width, the excavation depth, the ground height, and the like are input, these information are stored in the memory 16 as pipeline section measurement information relating to the location of the pipeline in the ground and the cross-sectional shape of the pipe ( S12).

When the pipe section measurement point information is input for each measurement point, the window is closed. Thereafter, when an operation for arranging auxiliary pipe elements related to the configuration of the pipe, such as manholes and power poles, is performed on the pipes on the display screen, together with the pipes constituting the pipes, the planes of the manholes and power poles are displayed. Information on the shape and the position on the pipeline is stored in the memory 16 as auxiliary pipeline plane measurement point information (S13, S14). For example, the measurement point No. When an operation for installing a manhole in the vicinity of 4 is performed, the planar shape and the position on the pipeline of the designated manhole are registered (stored). Thereafter, when it is necessary to register the depth of another pipe, for example, when it is necessary to register the depth of a drain pipe, the depth of the drain pipe is registered together with its shape (S15). Next, based on the pipe length, the pipe type, the shape of the manhole, and the pipe information, plane dimension line information relating to the plane dimensions and dimension lines of the pipe and each part of the manhole is generated, and the plane dimension line information is stored in a memory. 16 (S16).

Then, a process for creating such information is performed (S21). Next, while plotting information for each measurement point (S22), plotting is performed on the curve of the pipeline (S23). Further, based on the pipeline information of the pipeline and the pipeline information of the pipeline, a curve is drawn which indicates whether or not the pipeline is bent left or right with respect to a designated point. Next, when a curve is included in the pipeline, details of the curve are drawn based on the specifications (S24). Subsequently, a ground line indicating the ground height (elevation) is drawn based on the map information of the pipeline (S25).

Next, information on the vertical cross-sectional shape of the manhole and the position on the pipeline, that is, information on the auxiliary pipeline longitudinal cross-section, is generated based on the auxiliary pipeline flat-surface measurement information on the manhole planar shape and the position on the pipeline. The manhole MH is drawn according to this information (S26).

When the shape of the manhole MH is changed, information related to the shape of the manhole is updated. When the plan view information related to the pipeline to which the manhole MH belongs is updated, the plan view is changed and displayed according to the pipeline information and the auxiliary pipeline plane measurement point information among the updated (changed) plan view information. For example, as shown in FIG. 9B, the position of the manhole MH on the plan view is displayed in an updated state. In this case, the manhole MH at the original position is deleted, and the manhole MH is displayed at a new position (S44). When the plan view information is further updated, the longitudinal sectional view information is updated based on the updated plan view information, and the longitudinal sectional view is changed and displayed according to the updated longitudinal sectional view information (S45). That is, FIG.
The manhole MH shown in (a) is shifted to the position shown by the broken line, and the manhole MH at the original position is deleted.

According to the present embodiment, when the shape or position of the manhole MH is changed in the image-displayed vertical sectional view of the pipeline, the vertical sectional view and the plan view are changed in accordance with the change. Correction work can be easily performed.

Next, the drawing process of the cross sectional view will be described with reference to the flowchart of FIG.
