Hereinafter, in the present embodiment, the case of embedding a pipe which is an example of the embedded object will be described. In the construction relating to the burying of a pipe, it is necessary to bury a pipe of a predetermined diameter at a predetermined position and a predetermined depth. Therefore, the operator of the hydraulic shovel 100 must first excavate a groove for installing a pipe, install the pipe at a predetermined position of the excavated groove, and backfill the groove. Therefore, the design data is TIN (Triangulated Irregular Network) data (hereinafter referred to as design surface data for trench excavation) representing the shape of the trench for installing the tube, and after the trench is backfilled. It includes TIN data representing topography (hereinafter referred to as design surface data for backfilling). TIN data is three-dimensional data in which a surface is defined by a plurality of triangular polygons.

In the present embodiment, the planar position of the construction site means a position specified from the X coordinate and the Y coordinate of the on-site coordinate system represented by the X coordinate, the Y coordinate, and the Z coordinate.

The progress storage unit 233 stores the progress of the construction stage of the partial area in association with each of the plurality of partial areas obtained by dividing the pipe installation and construction area. The progress status of the construction stage is, for example, “not started / during”, “dwelling completed”, “installation completed / backing in progress”, or “backfilling completed”. That is, the progress status of the construction stage is information indicating which construction stage the progress has reached in a region where it is necessary to go through a plurality of construction stages until completion of construction. The plurality of partial areas are an example of a plurality of management points for managing the construction status of the construction area.
"Not started" indicates a stage before digging a ditch for burying a pipe, and "during digging" indicates a stage from the start of digging the ditch to the completion of the digging. “Excavation Completed” indicates a stage in which the trench has not been installed while the excavation of the ditch for embedding the tube is completed. The completion of the ditching means that the ditching has been performed to the depth indicated by the design surface data for ditching. "Installation complete" indicates the stage of installing the pipe in the groove, and "during backfilling" indicates the phase from the start of backfilling of the groove in which the pipe is installed to the completion of the backfilling. "Backfill complete" indicates the stage at which the pipe backfilling work has been completed. The completion of the backfill means that the backfill has been performed to the height indicated by the design surface data for backfilling.

  The map storage unit 234 stores a map image representing the topography of the construction site.

  The embedded object information storage unit 235 associates the embedded work area of the pipe with each of a plurality of divided partial areas and divides the planar position of the pipe embedded in the partial area, the embedded height (depth) of the pipe, the pipe The type, number of pipes, pipe diameter, pipe material, date and time of burial, repair history, and information on buried objects such as owner and builder are stored. The type of pipe is, for example, a water pipe, a gas pipe or the like. In addition, in the case of managing the buried object other than the tube in another embodiment, the type of cable such as an electric wire or an optical fiber cable or the type of accommodation facility such as an information box or an electric wire joint groove may be stored.

  The processor 210 includes a design data acquisition unit 211, a division unit 212, a target point identification unit 213, a measured value acquisition unit 214, a lowermost height identification unit 215, a progress identification unit 216, a progress output unit 217, and a progress acquisition unit 218. .

  The design data acquisition unit 211 acquires, from the design data storage unit 231, design data relating to a pipe embedding and construction area. The design data acquisition unit 211 may acquire design data from the outside of the construction management device 200. Here, "to acquire" is to acquire a new value. For example, "acquire" includes receiving a value, accepting an input of a value, reading a value from a table, and calculating another value from one value.

  The dividing unit 212 divides the pipe embedding work area into a plurality of partial areas based on the design data.

  The target point specifying unit 213 specifies a target point for determining the progress of the construction stage for each of the plurality of partial areas divided by the dividing unit 212. The target point is a point included in each partial area.

  The measured value acquisition unit 214 acquires point cloud data or cutting edge position data from the control device 125 of the hydraulic shovel 100. That is, the measurement value acquisition unit 214 acquires the measurement value of the current height of the object in the target area (the topography of the groove area at the time of digging and backfilling, or the tube at the time of installation).

  The lowest height specifying unit 215 specifies the lowest height of the cutting edge position data for a plurality of plane positions including at least the target point of the construction site based on the measurement value acquired by the measurement value acquisition unit 214. The lowest height identification unit 215 updates the lowest height stored in the lowest height storage unit 232. By updating the lowermost height of the cutting edge position at a plurality of positions, it is possible to specify the height of the excavated surface of the construction site at the “not started / during” stage. When the digging operation continues in the target area, the cutting edge of the bucket 113 gets into the lower part of the topography each time the digging is performed. Therefore, the lowest height in the said object area | region is updated downward at every excavation.

  The progress identifying unit 216 determines the progress status of the construction stage in each partial region ("not started / during", "drilling completed", "completed installation / backed back", "backed back", etc.) Identify if it is. The progress identification unit 216 updates the progress status of the construction stage stored in the progress storage unit 233 based on the identified progress status. The progress specifying unit 216 may, for example, compare the target height of the target point of each partial area with the measurement value of the target point to specify the progress of the construction stage of the partial area. The target height of the target point is the height of the target point in the design surface data for trench excavation. In this case, the progress specifying unit 216 specifies that the progress status is “drilling complete” based on the status of the digging from the “not started / during digging” stage, and updates the progress storage unit 233. Further, as described above, the progress identifying unit 216, instead of or in addition to specifying the progress based on the target height of the target point of each partial area and the measured value, information on the progress status input from the progress acquiring unit 218 The progress status of the construction stage in each partial area may be identified based on

The progress output unit 217 superimposes the progress status of the construction stage stored by the progress storage unit 233 on the map stored by the map storage unit 234 and outputs it. For example, the progress output unit 217 outputs a map representing the progress of the pipe installation and construction stage to another computer 300 via the network. Examples of the other computer 300 include a smartphone owned by an operator or a manager, a tablet terminal, a printer, or a PC installed in an office.
The progress acquiring unit 218 acquires the progress of the construction stage in the partial area from, for example, the administrator or the operator via the interface 240 or another computer 300, and outputs the acquired progress to the progress identifying unit 216.

<< construction management method >>
FIG. 5 is a diagram showing a construction management method using the construction management system according to the first embodiment.
When embedding a pipe, the operator of the hydraulic shovel 100 first excavates a groove for installing the pipe T, installs the pipe T in the excavated groove, and backfills the groove. Here, based on this procedure, an outline of a method for the construction management system 1 to manage the progress of the construction stage in the burial construction of the pipe T will be described.

The construction management apparatus 200 divides the embedding construction area of the pipe T into a plurality of partial areas, and specifies the groove height H1 and the backfilling height H2 for each partial area. The groove height H1 is the height of the bottom surface of the groove to be excavated for burying the pipe T. The refilling height H2 is the height of the ground after filling the groove in which the pipe T is installed. The groove height H1 and the backfill height H2 are both expressed in units of height in the on-site coordinate system.
The construction management device 200 identifies the height H1 of the groove based on the input design surface data for trench excavation, and identifies the back-back height H2 based on the design surface data for back-filling. At this point in time, since construction has not been performed for any partial area, the construction management device 200 identifies the progress of the construction stage of the partial area as “not started / during drilling” (stage P1).

  When the hydraulic shovel 100 excises the partial area in which the progress status of the construction stage is “not started / during”, the construction management device 200 acquires the lowermost height of the partial area from the lowermost height storage unit 232 . The lowermost height of the partial area is a value updated when the cutting edge of the hydraulic shovel 100 passes below the current lowermost height in the partial area, and is updated to the value of the height the cutting edge has passed Ru. That is, the lowermost height of the partial area represents the height of the present topography in the partial area. The lowermost height identifying unit 215 updates the lowermost height based on the cutting edge position data transmitted from the control device 125 during the excavation work of the hydraulic shovel 100. When the difference between the height H1 of the groove in the relevant partial area in the design data and the measured value of the lowermost height acquired from the lowermost height storage unit 232 in the design data becomes equal to or less than a predetermined threshold value The progress of the construction stage of the partial area is identified as "drilling completed" (stage P2).

  When the progress status of the construction stage is "drilling completed", the operator or another worker installs the pipe T at a predetermined position of the excavated ditch. Thereafter, the control device 125 of the hydraulic shovel 100 measures the height of the partial area according to the operation of the operator, and transmits the measured value (point cloud data or cutting edge position data). For example, when obtaining a measurement value related to the blade position data, the control device 125 causes the construction management device 200 to transmit the blade position data by pressing the predetermined measurement button while the operator applies the blade edge of the bucket 113 to the pipe T. Send. In addition, for example, when obtaining a measurement value related to point cloud data, the control device 125 causes the construction management device 200 to set the stereo camera by pressing a predetermined imaging button in a state where the tube T appears in the imaging range of the stereo camera 122 The point cloud data measured by 122 is transmitted. If the difference between the height obtained by adding the diameter H3 of the pipe T to the height H1 of the groove in the partial area in the design data and the measured value of the height is equal to or less than a predetermined threshold value, the construction management device 200 The progress of the construction stage of the area is identified as “installation complete / backing in progress” (stage P3).

  When the progress status of the construction stage is "installation complete / backing in progress", the operator starts backfilling of the partial area. When the backfilling is completed, the control device 125 of the hydraulic shovel 100 measures the height of the partial area according to the operation of the operator, and transmits the measured value (point cloud data or cutting edge position data). For example, when obtaining a measurement value related to the blade position data, the control device 125 causes the construction management device 200 to transmit the blade position data by pressing the predetermined measurement button while the operator applies the blade edge of the bucket 113 to the pipe T. Send. In addition, for example, when obtaining a measurement value related to point cloud data, the control device 125 causes the construction management device 200 to set the stereo camera by pressing a predetermined imaging button in a state where the tube T appears in the imaging range of the stereo camera 122 The point cloud data measured by 122 is transmitted. If the difference between the backfill height H2 of the groove in the partial area in the design data and the measured value of the height is equal to or less than a predetermined threshold in the design data, the construction management device 200 Identify as "backfill complete" (step P4).

FIG. 6 is a flowchart showing an initial process of the construction management device according to the first embodiment.
In order to realize the above-mentioned construction management, the construction management apparatus 200 executes the following initial processing.
When the construction management device 200 starts the progress management of the burial construction of the pipe T, first, the design data acquisition unit 211 acquires design data relating to the construction area of the pipe T from the design data storage unit 231 (step S1). Next, the dividing unit 212 divides the construction area indicated by the acquired design data into a plurality of partial areas (step S2). The method of dividing the work area by the dividing unit 212 will be described later. The division of the work area by the dividing unit 212 does not necessarily have to be performed, and the partial area may be determined in advance as a part of the construction area.

The dividing unit 212 assigns an ID to each of the plurality of partial areas, and causes the progress storage unit 233 to store the IDs and positions of the plurality of partial areas (step S3). Next, the target point identification unit 213 identifies a target point included in each partial area (step S4). The target points include, for example, any point within the partial area, the center of gravity of the partial area, the center of the minimum circumscribed circle of the partial area, and the center of the maximum internal circle of the partial area.
The progress specifying unit 216 specifies the progress of the construction stage of each partial area as “not started / during digging” as an initial value, and stores the progress in the progress storage unit 233 in association with each partial area (step S5) ). Thereafter, the progress identifying unit 216 performs progress determination processing described later as the construction progresses, and updates the progress status of the construction stage in each partial region.

Here, an example of the method of dividing the work area in step S2 will be described. FIG. 7 is a diagram showing a method of dividing the work area according to the first embodiment.
The dividing unit 212 generates the outer polygon G1 of the construction area by tracing the outer periphery of the TIN data included in the read design data (step S21). Next, the dividing unit 212 divides the generated outer polygon G1 into a plurality of rectangular parallelepipeds G2 (step S22). At this time, the dividing unit 212 performs division such that the area of each rectangular parallelepiped G2 is maximized. Thus, the outer polygon G1 is divided into a plurality of rectangular parallelepipeds G2 and a polygon G3 connecting the rectangular parallelepipeds. Next, the dividing unit 212 divides the plurality of rectangular parallelepipeds G2 in the longitudinal direction (that is, the extending direction of the work area) at regular intervals to obtain a plurality of small rectangular parallelepipeds G4 (step S23). The dividing unit 212 sets the divided polygon G3 and the plurality of small rectangular parallelepipeds G4 as partial regions.

FIG. 8 is a flowchart showing the progress determination process of the construction management device according to the first embodiment.
When the initial process is completed, the construction management device 200 executes the following progress determination process for each of the plurality of partial areas at fixed time intervals.
The progress identification unit 216 of the construction management device 200 acquires the current progress status associated with the target partial area from the progress storage section 233 when specifying the progress status at the construction stage of the target partial area Step S101). The progress identifying unit 216 determines whether the acquired progress status is “not started / during digging” (step S102). When the progress status is “not started / during digging” (step S102: YES), the lowermost height identification unit 215 determines from the lowermost height storage unit 232 the lowermost height of the cutting edge position at the target point of the relevant partial area. Is read out (step S103). The progress identifying unit 216 determines whether or not the difference between the height H1 of the groove related to the target point of the partial area in the design data and the read lowermost height is equal to or less than a predetermined threshold (step S104). ). If the difference between the height H1 of the groove related to the target point of the partial area in the design data and the lowermost read height is equal to or less than the predetermined threshold (step S104: YES), the progress specifying unit 216 proceeds with The progress status stored in association with the partial area by the storage unit 233 is rewritten as “digging complete” (step S105). If the difference between the height H1 of the groove related to the target point in the design data and the lowermost read height is larger than the predetermined threshold (step S104: NO), the progress specifying unit 216 Do not update the progress status from "Not started / during drilling".

If the acquired progress status is not “not started / during digging” (step S102: NO), the progress identifying unit 216 determines whether the acquired progress status is “drilling completed” (step S106). When the progress status is “digging complete” (step S106: YES), the measured value acquiring unit 214 measures the embedded height of the pipe T related to the partial area from the control device of the hydraulic shovel 100 (point cloud data or It is determined whether or not the cutting edge position data is received (step S107). When the measured value of the height is received (step S107: YES), the progress identifying unit 216 receives the sum of the height H1 of the groove and the diameter H3 of the pipe T related to the target point of the partial area in the design data It is determined whether the difference between the measured value and the height of the target point is equal to or less than a predetermined threshold (step S108). When the difference between the sum of the height H1 of the groove related to the target point of the partial area in the design data and the diameter H3 of the pipe T and the embedding height of the pipe T indicated by the measured value is equal to or less than a predetermined threshold (step S108 (YES: YES), the progress specifying unit 216 rewrites the progress status stored in the progress storage unit 233 in association with the partial area to “installation completed / backing in progress” (step S109).
In the case where the difference between the sum of the height H1 of the groove relating to the target point in the design data and the diameter H3 of the pipe T and the buried height of the received pipe T is larger than a predetermined threshold (step S108: NO) When the measurement value of the burial height of T is not received (step S107: NO), the progress specifying unit 216 does not update the progress status related to the partial area from “dwelling completed”.

  If the acquired progress status is not “digging completed” (step S106: NO), the progress identifying unit 216 determines whether the acquired progress status is “installation completed / backing in progress” (step S110). When the progress status is “installation complete / backing in progress” (step S110: YES), the measurement value acquisition unit 214 measures the soil work height by backfilling pertaining to the partial area from the control device of the hydraulic shovel 100 ( It is determined whether point cloud data or cutting edge position data has been received (step S111). When the measurement value of the construction height is received (step S111: YES), the progress identifying unit 216 indicates the backfill height H2 of the groove related to the target point of the partial area in the design data and the target indicated by the received measurement value. It is determined whether the difference between the point and the work height is equal to or less than a predetermined threshold (step S112). When the difference between the backfill height H2 of the groove related to the target point of the partial area in the design data and the earthwork height of the target point indicated by the measurement value is equal to or less than a predetermined threshold (step S112: YES), the progress identifying unit At 216, the progress status stored in the progress storage unit 233 in association with the partial area is rewritten as "backfill completion" (step S113). If the difference between the backfill height H2 of the groove related to the target point in the design data and the earthwork height of the target point indicated by the received measurement value is larger than a predetermined threshold (step S112: NO), or the earthwork height When the measurement value of (1) is not received (step S111: NO), the progress specifying unit 216 does not update the progress related to the partial area from “installation complete / backing in progress”.

  If the acquired progress status is “backfill complete” (step S110: NO), since the construction pertaining to the relevant partial area is completed, the progress identifying unit 216 updates the progress status pertaining to the relevant partial area Absent.

  The construction management apparatus 200 can maintain the progress status of the construction stage in each partial area stored in the progress storage unit 233 in the latest state by repeatedly executing the processing illustrated in FIG. 8. Then, when receiving an output request for the progress status from another external computer via the network, the construction management device 200 outputs information indicating the progress status stored in the progress storage unit 233 to the other computer. Examples of other computers include a smartphone owned by an operator or a manager, a tablet terminal, a printer, or a PC installed in an office. The above-mentioned progress determination process is not necessarily required. For example, when the progress can be acquired by the progress acquiring unit 218, the construction management device 200 may not perform the progress determination process. Specifically, step S103 to step S105, step S107 to step S109, and step S111 to step S113 in the flowchart may not necessarily be performed.

FIG. 9 is a flowchart showing the progress output process of the construction management device according to the first embodiment.
When the progress output unit 217 of the construction management device 200 receives an output request for the progress status from another external computer (step S201), the progress output unit 217 reads a map image representing the topography of the construction site from the map storage unit 234 (step S202). The progress output unit 217 reads the progress status of each partial area from the progress storage unit 233 (step S203). The progress output unit 217 changes the color of the portion corresponding to each partial area in the map image according to the read progress status (step S204). For example, the progress output unit 217 sets the partial area of "not started / dowing" in the map image to red, the partial area of "drilling completed" to green, and the partial area of "installation completed / backing back" to blue. In addition, change the partial area of "Backfill complete" to blue.
Then, the progress output unit 217 outputs the map image in which the color of the partial area is changed, to another computer that is the transmission source of the output request (step S205).

FIG. 10 is a diagram showing an example of a map image output by the construction management device according to the first embodiment.
The progress output unit 217 is, as shown in FIG. 10, a map image including the construction area of the pipe T to be embedded under the road St, and displays each partial area R of the construction area in a different manner according to the progress. Output what you want. Thereby, the management of a construction site can recognize the progress of burial construction along the extension direction of pipe T. Moreover, the manager of the construction site can accurately recognize the relationship between the position of the construction site and the progress of the construction by superimposing the progress of the construction on the map and outputting the same on the same screen. In addition, since the construction situation of each partial area R is known after dividing the area into a plurality of partial areas R, the manager of the construction site can easily progress not only the progress for each partial area R, but also the entire progress of the construction area Can be understood. In addition, although the shape of partial area R which concerns on 1st Embodiment is a rectangle, it is not restricted to this. For example, the shape of the partial region R according to another embodiment may be another polygon, or may be a shape including at least a part of a curve, or a point or a line having no area. May be

<< Operation / Effect >>
The construction management apparatus 200 which concerns on 1st Embodiment specifies the progress in the construction stage of each partial area | region in a construction area | region, and outputs the progress. Thereby, the manager of the construction site can recognize the progress of the entire construction area. In addition, in 1st Embodiment, although a construction area | region is a burial construction area | region of pipe | tube T, it is not restricted to this. For example, the construction area according to the other embodiment may be another construction area such as a groove construction area, a land filling construction area of a groove already formed, a road construction area, a river earth construction construction area, or a gutter construction area. . In addition, you may call a linear construction area the construction area extended linearly, such as the embedding construction area | region of pipe | tube T, a groove construction area, the landfill construction area of the already formed groove, a road construction area, a river earth construction construction area, a gutter construction area. The linear application area may have a relatively short width with respect to the length. Here, the term “linear” does not necessarily have to be a straight line, and may be a curve or a shape composed of a combination of a curve and a straight line.
Moreover, the name of the progress of the construction stage may be different depending on the type of construction area. For example, in the case of road construction, “filling stage”, “road surface / slope forming stage”, “rolling stage”, and “asphalt pavement stage” may be set as the progress status.

  Moreover, although the embedding | flush-mounting target object which concerns on 1st Embodiment is pipe | tube T, it is not restricted to this. For example, the embedded object according to another embodiment may be a cable, or another long object such as a pipe or a cable storage facility.

  Moreover, the construction management apparatus 200 which concerns on 1st Embodiment specifies the progress of construction using the height information of the said groove | channel. Thereby, the construction management apparatus 200 which concerns on 1st Embodiment can specify whether digging of the ditch which should install pipe T as completion is completed. Further, the design data according to the first embodiment includes the backfilling height information of the groove in which the pipe T is installed, and the construction management device 200 specifies the progress of construction using the backfilling height information. Do. Thereby, the construction management apparatus 200 which concerns on 1st Embodiment can specify whether backfilling of the groove | channel in which the pipe | tube T was installed was completed as progress. In another embodiment, when it is not necessary to backfill the groove, the design data may not necessarily include the backfill height information of the groove. In addition, design data according to another embodiment may not necessarily have height data. For example, the design data may consist of only planar position data when viewed in plan from the height direction of the construction area. The design data may be composed of latitude data, longitude data and height data in the site coordinate system, or may be composed of latitude data and longitude data.

  Since the design data according to the first embodiment includes both groove height information and groove backfill height information in the same partial region, the construction management device 200 determines the height of the groove included in the design data. Whether the ditch excavation has been completed using the depth information, and if the ditch excavation has been completed, whether the ditch backfill has been completed using the backfill height information included in the design data By specifying whether or not it is possible to accurately specify the progress of the backfilling of the pipe T.

The construction management device 200 according to the first embodiment identifies a plurality of partial areas obtained by dividing the construction area in the extending direction, and identifies the progress of each of the plurality of partial areas. Thereby, the management of a construction site can recognize the progress of burial construction along the extension direction of pipe T. In particular, when there is only one partial area in the width direction of the construction area, the manager can easily recognize the progress.
On the other hand, in another embodiment, the construction management device 200 may specify only the progress of the entire construction area without dividing the construction area, or a plurality of parts obtained by dividing the construction area in the width direction. The progress may be identified based on the area or a plurality of partial areas obtained by dividing the construction area by mesh. Further, the partial area may be a partial area of the construction area, and is not necessarily limited to the division of the construction area. The partial areas do not necessarily have to be provided at equal intervals in the construction area. Further, instead of the partial area having the surface, the progress status of the construction area may be managed by a plurality of control points having no surface, for example, points or lines.
When the construction management device 200 manages the amount of work in addition to the management of the progress status, the construction management device 200 performs management based on the partial area in the management of the progress status, and in the management of the amount of work, such as mesh Management based on other management units may be performed.

  By the way, in the construction management of the construction area according to the comparative example, the whole construction area is classified into a cutting area and a filling area, the progress of cutting construction for the cutting area and the progress of filling construction for the filling area It is known to manage. In such construction management, progress may be confirmed by displaying a change in the amount of work and the situation in each area obtained by dividing the construction area by a mesh or the like.

On the other hand, the construction area may go through a plurality of construction stages (in the case of buried construction, trench excavation, buried object installation, backfilling, etc.) until completion of construction. In addition, the construction of the construction area such as a pipe or a road starts, for example, from either of the two ends, and construction is sequentially performed toward the opposite end, as shown in FIG. Construction may be done along the existing direction.
Therefore, when the display method of the progress situation performed by dividing the construction area by mesh and based on the amount of earthwork of the cut soil or the fill as in the comparative example described above is applied to construction through a plurality of construction stages, the progress of the construction area It is difficult to recognize which construction stage is in, and it is also difficult to recognize the progress of the entire construction area. On the other hand, the construction management device 200 according to the first embodiment identifies and outputs the progress of the construction stage in each partial area R, thereby making the manager at first glance understand the progress of the entire construction area It becomes possible.

  The construction management device 200 according to the first embodiment identifies the progress based on the height of the target point, which is a point in the construction area. When the target point is located within the construction area, the progress of the burial construction can be accurately identified. For example, if the construction site is divided by meshes at regular intervals as in the comparative example described above, and each central point of the mesh is set as a target point, when the width of the construction area is narrower than the width of the mesh, There is a possibility that the construction area will be located in the area, and the progress of the burial work can not be identified accurately.

  The construction management apparatus 200 which concerns on 1st Embodiment outputs the map which displays each of several partial area | regions in a construction area according to progress. Thereby, the manager of the construction site can easily visually recognize the progress of the burial construction. In addition, in the map image which concerns on 1st Embodiment, although the color of a partial area is changed according to a progress condition, it is not restricted to this. For example, in a map image according to another embodiment, the partial area is made different depending on the progress according to other modes such as thickness of outline of partial area, line type of outline, blinking speed, display of progress with letters. It may be displayed on the same screen. Moreover, the construction management apparatus 200 which concerns on other embodiment does not necessarily need to superimpose a progress on a map image. For example, the construction management device 200 may output in the form of a table in which each partial area and the progress status are simply associated, or in other forms.

  The embedded object information storage unit 235 of the construction management device 200 according to the first embodiment stores, for each partial area, the diameter, the type, the embedded height, and the like of the pipe T. Thereby, after the completion of the burial construction of the pipe T, when it is necessary to excavate the area, the operator is buried by referring to the information stored in the buried object information storage unit 235. The diameter, type and burial height of the tube T can be recognized. Thereby, the operator can operate the working machine so as not to break the embedded tube T.

The construction management apparatus 200 according to the first embodiment determines whether or not the excavation in step S104 is completed, determines whether or not the installation of the pipe T in steps S107 to S108 is completed, and in steps S111 to S112. Although the determination as to whether or not the backfilling is completed is automatically performed, the embodiment is not limited thereto. For example, in another embodiment, at least one of the determination of whether the excavation has been completed, the installation of the pipe T, and the backfilling is determined by the operator. It may be done. Also, in this case, the operator may input the progress of each partial area using the input device in the interface 240 or the other computer 300 based on the above determination. The progress acquisition unit 218 acquires the progress status from the input device. The progress specifying unit 216 specifies the progress in the partial area based on the input progress, and the progress output unit 217 outputs the progress in the partial area based on the input progress. Thereby, even when the height of each partial area can not be measured by the control device 125, the construction management device 200 determines the progress in the construction stage in each partial area, depending on the judgment of the operator or other workers. Because you can, you can do progress management surely.
In still other embodiments, the installation depth and backfilling height of the tube T may be manually input by the operator.

  In the first embodiment, the progress status of the construction stage is represented by four: "not started / during", "drilling completed", "installation completed / backing back", and "backfilling completed". However, it is not limited to this. For example, in another embodiment, "not started / dowing" may be expressed separately as "not started" and "during digging", or "installation complete / backing back" is "completed installation" And “in backfilling” may be separately represented.

  Further, in the first embodiment, the construction management device 200 is provided separately from the other computer 300, but is not limited thereto. For example, in the construction management system 1 according to another embodiment, a part or all of the functions of the construction management apparatus 200 may be provided to another computer 300.

  As mentioned above, although one embodiment was described in detail with reference to drawings, a concrete configuration is not restricted to the above-mentioned thing, It is possible to do various design changes etc.
