Description

[Technical field]

[0001] The present invention relates to a process plan creation system, a process plan creation method, and a program for creating a process plan for water pipe construction. [Background technology]

[0002] In general, in construction work, a process plan is created, and work is carried out according to the created process plan. As a construction process creation system, for example, as disclosed in Patent Document 1, a construction process creation system is known that includes a calculation unit that calculates the construction period of each of the multiple construction works for each of the multiple work sections based on the amount of work of the construction object for each of the multiple work sections, a labor-hour count that represents the ratio of the labor hours to the amount of work in the multiple work sections and the multiple construction works, a difficulty coefficient, and a modularization rate that represents the ratio of the number of assembly points in a module that is assembled in advance at a location other than the work section to the total number of assembly points in the work section. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 5665759 Summary of the Invention [Problem to be solved by the invention]

[0004] The construction schedule creation system of the above-mentioned Patent Document 1 calculates the construction time based on the construction volume of the construction object, the man-hour count, the difficulty coefficient, and the modularization rate. In contrast, in the case of water pipe construction, modularization is difficult, and after excavating the ground at the site, it is necessary to connect the water pipes one by one underground and backfill them. Therefore, in water pipe construction, the process changes greatly depending on the diameter, length, type, number, and arrangement of each water pipe.

[0005] Therefore, in water pipe construction, simple schedule calculations are difficult, and the schedules are created manually by skilled workers based on their experience and knowledge. Therefore, the creation of schedules for water pipe construction requires skilled workers to take time to create them, and it is not easy to create them.

[0006] An object of the present invention is to realize a process plan creation system that can easily create a process plan for water pipe construction. [Means for solving the problem]

[0007] A process plan creation system for water pipe construction according to one embodiment of the present invention creates a process plan for water pipe construction. The process plan creation system has an information acquisition unit that acquires water pipe related information related to at least one of the diameter, length, type, number, and arrangement of water pipes used in water pipe construction, a process time calculation unit that calculates a process time including a working time for each process of the water pipe construction based on the water pipe related information acquired by the information acquisition unit, and a process plan creation unit that creates a process plan for at least a part of the water pipe construction using the process time for each process calculated by the process time calculation unit (first configuration).

[0008] With the above-mentioned configuration, the process time for each process of the water pipe construction work can be calculated based on the water pipe related information, and the calculated process time can be used to create a process plan for at least a part of the water pipe construction work. Therefore, the process plan for the water pipe construction work can be automatically and easily created. The process plan includes at least one of a daily process plan and an overall process plan. The overall process plan means a process plan from the start to the end of the water pipe construction work, and includes, for example, a weekly process plan, a monthly process plan, an annual process plan, etc.

[0009] In the first configuration, the information acquisition unit acquires water pipe work related information related to the water pipe work in addition to the water pipe related information. The process time calculation unit calculates the process time using the water pipe related information and the water pipe work related information acquired by the information acquisition unit (second configuration).

[0010] This allows the water pipe construction work schedule to be created using water pipe construction work-related information related to the water pipe construction work in addition to the water pipe-related information, thereby allowing the water pipe construction work schedule to be created with higher accuracy.

[0011] In the second configuration, the water pipe construction related information includes above-ground related information including information related to the aboveground of the location where the water pipe will be buried, and underground related information including information related to the underground of the location where the water pipe will be buried (third configuration).

[0012] This makes it possible to calculate the time required for each process of water pipe construction work, taking into account aboveground-related information and underground-related information that have a significant impact on the water pipe construction work. Therefore, it is possible to create a process plan for water pipe construction work with higher accuracy.

[0013] In the third configuration, the ground-related information includes ground surroundings-related information related to the ground surroundings of the location where the water pipe is to be buried, and road condition-related information related to the road conditions of the location where the water pipe is to be buried (fourth configuration).

[0014] This makes it possible to calculate the time required for each stage of water pipe construction work by taking into account ground surroundings-related information and road conditions-related information, which are among ground-related information that have a significant impact on water pipe construction work. Therefore, it is possible to create a more accurate process plan for water pipe construction work.

[0015] In the third or fourth configuration, the underground-related information includes information related to at least one of underground obstacles, road structure, soil quality, and groundwater (fifth configuration).

[0016] This makes it possible to calculate the time required for each process of water pipe construction, taking into account information related to at least one of underground obstacles, road structure, soil quality, and groundwater, which have a significant impact on water pipe construction. This makes it possible to create a process plan for water pipe construction with higher accuracy.

[0017] In any one of the second to fifth configurations, the process time calculation unit calculates a reserve time for each process of the water pipe construction based on the water pipe related information and the water pipe construction related information. The process plan creation unit creates a process plan for at least a part of the water pipe construction, taking into account not only the process time of each process but also the reserve time (sixth configuration).

[0018] This allows the creation of a water pipe construction schedule that takes into account risks such as when the schedule needs to be changed due to unexpected buried objects underground or when the schedule needs to be changed due to conditions above ground (such as when there are times when construction cannot be done at parking lots or store entrances), etc. This makes it possible to create a water pipe construction schedule with greater accuracy.

[0019] In the sixth configuration, the process time calculation unit includes a reserve time correction unit that corrects the reserve time in each process of water pipe construction based on past results (seventh configuration).

[0020] This allows the reserve time for each process of water pipe construction to be calculated with high accuracy based on past results. For example, since parameters related to water pipe construction differ for each work site, the reserve time can be corrected according to the parameters to reflect past results in the reserve time. In addition, the reserve time can be calculated with higher accuracy by correcting the reserve time based on past weather data for the time of water pipe construction.

[0021] Therefore, the corrected spare time can be used to create a more accurate process plan for water pipe construction.

[0022] In any one of the second to seventh configurations, the information acquisition unit acquires, as the water pipe work related information, construction suspension related information related to dates and times when water pipe work is not performed. The process plan creation unit creates a process plan for at least a part of the water pipe work using the construction suspension related information acquired by the information acquisition unit and the process time of each process calculated by the process time calculation unit (eighth configuration).

[0023] This makes it possible to create a schedule for water pipe construction work excluding periods or time periods when water pipe construction work is suspended, thereby making it possible to create a schedule for water pipe construction work with greater accuracy.

[0024] In any one of the first to eighth configurations, the system further includes a progress status related information acquisition unit that acquires progress status related information relating to the progress of water pipe construction work, and a process plan correction unit that uses the progress status related information acquired by the progress status related information acquisition unit to correct the process plan created by the process plan creation unit (ninth configuration).

[0025] This allows the water pipe construction work schedule to be revised in accordance with the actual progress of the water pipe construction work, and therefore allows the water pipe construction work schedule to be created more accurately in accordance with the actual situation.

[0026] A process plan creation method for water pipe construction according to one embodiment of the present invention is a method for creating a process plan for water pipe construction. The process plan creation method includes an information acquisition step of acquiring water pipe related information related to at least one of the diameter, length, type, number, and arrangement of water pipes used in the water pipe construction, a process time calculation step of calculating a process time including the working time of each process of the water pipe construction based on the water pipe related information acquired in the information acquisition step, and a process plan creation step of creating a process plan for at least a part of the water pipe construction using the process time of each process calculated in the process time calculation step (first method).

[0027] The above-mentioned method allows the process time of each process of water pipe construction to be calculated based on the water pipe related information, and the calculated process time can be used to create a process plan for at least a part of the water pipe construction. Therefore, the process plan for water pipe construction can be automatically and easily created.

[0028] A program for creating a process plan for water pipe construction according to one embodiment of the present invention is a program for creating a process plan for water pipe construction, which causes a computer to acquire water pipe-related information related to at least one of the diameter, length, type, number, and arrangement of water pipes used in the water pipe construction, calculate process times including work times for each process of the water pipe construction based on the acquired water pipe-related information, and create a process plan for at least a part of the water pipe construction using the calculated process times for each process (tenth configuration).

[0029] With the above-mentioned configuration, the process time for each process of the water pipe construction work can be calculated based on the water pipe related information, and the calculated process time can be used to create a process plan for at least a part of the water pipe construction work. Therefore, the process plan for the water pipe construction work can be automatically and easily created. Effect of the Invention

[0030] A process plan creation system for water pipe construction according to one embodiment of the present invention calculates process times, including working times, for each process of the water pipe construction based on water pipe-related information relating to at least one of the diameter, length, type, number, and placement of the water pipes used in the water pipe construction, and creates a process plan for at least a portion of the water pipe construction using the calculated process times for each process.

[0031] This allows the process time for each process of the water pipe construction work to be calculated based on the water pipe related information, and the calculated process time can be used to create a process plan for at least a part of the water pipe construction work. Therefore, the process plan for the water pipe construction work can be automatically and easily created. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0033] Each embodiment will be described below with reference to the drawings. In each drawing, the same parts are given the same reference numerals, and the description of the same parts will not be repeated. Note that the dimensions of the components in each drawing do not faithfully represent the actual dimensions of the components and the dimensional ratios of each component.

[0034] In the following description, the terms "fix," "connect," and "attach" (hereinafter referred to as "fixing") include not only cases where members are directly fixed to each other, but also cases where members are fixed to each other via other members. In other words, in the following description, the terms "fixing" include the meanings of direct and indirect fixing of members to each other.

[0035] [Embodiment 1] (Water pipe construction process planning system) Fig. 1 is a functional block diagram showing a schematic configuration of a process plan creation system 1 according to a first embodiment of the present invention. The process plan creation system 1 creates and outputs a daily or monthly process plan for water pipe construction as shown in Fig. 2 and Fig. 3. The process plan creation system 1 may be configured, for example, by a computer device, or may have a computer device and a mobile terminal capable of transmitting and receiving data to and from the computer device via a communication device.

[0036] The water pipe construction means construction to bury a water pipe W in the ground. The water pipe construction includes not only construction to newly bury a water pipe W in the ground, but also construction to renew a water pipe W buried in the ground. The construction to newly bury a water pipe W in the ground among the water pipe construction includes a water pipe laying process. The water pipe laying process includes a daily process and a monthly process. The daily process includes an excavation process, a piping process, and a backfilling process. The monthly process includes the daily process for the number of process days. The monthly process may include a demarcation line process of drawing demarcation lines on the surface of a road. In the following, construction to newly bury a water pipe W in the ground will be described as the water pipe construction.

[0037] Among the water pipe construction works, the construction work for updating the water pipe W includes an excavation process, a piping removal process, a piping process, and a backfilling process as daily processes.

[0038] Each step of the daily water pipe construction work will be briefly described with reference to Fig. 4 to Fig. 7. Fig. 4 is a diagram showing a schematic diagram of excavating the ground using a work machine M. Fig. 5 is a diagram showing a schematic diagram of placing a water pipe W in a trench L formed by excavation. Fig. 6 is a diagram showing a schematic diagram of joining water pipes W together. Fig. 7 is a diagram showing a schematic diagram of burying a water pipe W using a work machine M.

[0039] In water pipe construction, first, as shown in Fig. 4, an excavation process is performed in which the ground is excavated using a work machine M. Although not specifically shown in Fig. 4, the surface of the ground is paved with asphalt. Therefore, in the excavation process, the work machine M excavates the asphalt and then excavates the ground. In the excavation process, the ground is excavated so as to form a trench L in which a water pipe W can be placed.

[0040] Next, as shown in Fig. 5, water pipes W are placed in a trench L formed by excavation. The water pipes W are carried into the trench L, for example, by using a work machine M. The water pipes W carried into the trench L are joined together, as shown in Fig. 6. The process of carrying the water pipes W into the trench L and joining them together in this manner is the piping process.

[0041] Thereafter, in the water pipe construction work, a backfilling process is carried out in which the joined water pipe W is backfilled in the trench L using a work machine M as shown in Fig. 7. Fig. 9 is a diagram showing a schematic configuration of a road R. The road R has, from the top, a surface layer R1, an upper subgrade R2, a lower subgrade R3, and a roadbed R4. When backfilling the water pipe W in the trench L, the trench L is backfilled in the order of the roadbed R4, the lower subgrade R3, the upper subgrade R2, and the surface layer R1 so that the road configuration becomes the configuration shown in Fig. 9.

[0042] In addition, in water pipe construction, after the excavation process, a retaining process as shown in Fig. 8 may be performed. In this retaining process, a sheet pile P is used to reinforce the side of the trench L excavated in the excavation process. In the retaining process, the entire side of the trench L may be reinforced, or only a part of the side of the trench L may be reinforced.

[0043] As shown in FIG. 1, the process plan creation system 1 includes an information acquisition unit 11, a plan control unit 15, a process time calculation unit 21, and a process plan creation unit 31.

[0044] The information acquisition unit 11 acquires water pipe related information and water pipe construction related information. The water pipe related information includes information related to at least one of the diameter, length, type (straight pipe, irregular pipe, T-shaped pipe, cut pipe, etc.), number, and arrangement of water pipes used in water pipe construction. The water pipe related information is information obtained from, for example, a water pipe pipeline diagram. That is, the water pipe related information may be obtained automatically from a device that generates the pipeline diagram. The water pipe related information may be obtained by input, or may be obtained from the result of calculation by a calculation device.

[0045] The water pipe construction related information includes information related to the water pipe construction. Specifically, the water pipe construction related information includes information related to site conditions. The information related to site conditions includes at least one of information related to available work time, available work personnel, the type and number of work machines to be used, whether parallel work can be performed, whether parallel use of work machines can be performed, transportation time for soil and water pipes, etc., whether test excavation is performed, etc.

[0046] The water pipe construction related information includes aboveground related information and underground related information. The aboveground related information includes information related to the aboveground of the location where the water pipe will be buried. Specifically, the aboveground related information includes aboveground surroundings related information and road condition related information. The aboveground surroundings related information includes information on the environment near the location where the water pipe construction will be performed (facilities (houses, stores, parking lots, etc.) facing the construction site, whether the construction site is in the city or suburbs, etc.). The road condition related information includes traffic information at the location where the water pipe construction will be performed, and if the location where the water pipe construction will be performed is a road, at least one of information on the width of the road and the number of lanes.

[0047] The underground-related information includes information related to the underground of the place where the water pipe is buried. In detail, the underground-related information includes information related to at least one of underground obstacles (underground structures such as crossing pipes, other buried objects, etc.), road structure, soil quality, and groundwater.

[0048] That is, the underground related information may include information on the type, size, location, etc. of underground obstacles. The underground related information may include information on road structure, such as the thickness and characteristics of the pavement and roadbed. The underground related information may include information on the soil quality (sand, silt, clay, etc.) at the excavation location. The underground related information may include information on the location and amount of groundwater. The underground related information may include information on whether retaining walls are necessary, the type of retaining walls (aluminum sheet piles, wooden sheet piles, lightweight steel sheet piles, H-shaped steel horizontal sheet piles, etc.), retaining wall construction method (building in, driving in, etc.), and the location and range of retaining walls.

[0049] The information acquisition unit 11 also acquires information on the construction period and possible construction dates as water pipe construction related information. The information on the construction period and possible construction dates acquired by the information acquisition unit 11 is used when the construction plan creation unit 31 creates a construction plan.

[0050] The information acquisition unit 11 may acquire construction suspension related information related to the date and time when water pipe construction is not performed as the water pipe construction related information. In this case, the process plan creation unit 31 creates a process plan for at least a part of the water pipe construction using the construction suspension related information acquired by the information acquisition unit 11 and the process time of each process calculated by the process time calculation unit 21 described later.

[0051] Based on the water pipe related information and water pipe work related information acquired by the information acquisition unit 11, the plan control unit 15 determines the work conditions necessary for creating a water pipe work schedule from among the information that cannot be obtained by the information acquisition unit 11. Specifically, the plan control unit 15 selects the work scope to be calculated by the work time calculation unit 21 described later, and determines the conditions for retaining earth work (necessary or unnecessary, scope of application, etc.) and the conditions for trial excavation (necessary or unnecessary, number of trial excavation points, etc.). The work scope selected by the plan control unit 15 and the conditions for retaining earth work and the conditions for trial excavation determined by the plan control unit 15 are output to the work time calculation unit 21 as part of the water pipe work related information.

[0052] The process time calculation unit 21 calculates a process time including the work time of each process of water pipe construction based on the water pipe related information and the water pipe construction related information acquired by the information acquisition unit 11. The process time calculation unit 21 calculates the work time required to bury one water pipe based on the water pipe related information and the water pipe construction related information, for example. FIG. 10 is a diagram showing an example of a result of calculating the work time of each process of water pipe construction. In FIG. 10, the work time of each process is displayed together with the water pipe pipeline for explanation. The process plan creation system 1 may display the work time of each process together with the water pipe pipeline as shown in FIG. 10, or may display only the work time of each process in a list.

[0053] The process time calculation unit 21 outputs the work time calculated for each process to the process plan creation unit 31 described later as process time data.

[0054] In addition, the process time calculation unit 21 may calculate the work time required to bury one water pipe by using the work time corresponding to the water pipe related information and the work time corresponding to the water pipe work related information, or may calculate the work time required to bury one water pipe by taking into account a coefficient corresponding to the water pipe related information and a coefficient corresponding to the water pipe work related information with respect to a standard work time.

[0055] The process time calculation unit 21 may calculate a reserve time for each process of the water pipe construction based on the water pipe related information and the water pipe construction related information. The reserve time may be included in the water pipe construction related information, or the process time calculation unit 21 may calculate the reserve time based on the water pipe related information and the water pipe construction related information, taking into account factors that delay the process time of each process. For example, the process time calculation unit 21 may calculate a reserve time for the process time of excavation and piping based on the probability of the presence of underground obstacles in the underground related information. That is, the process time calculation unit 21 may calculate the reserve time taking into account the probability of an event occurring in each process.

[0056] The process plan creation unit 31 creates a process plan for at least a part of the water pipe construction work using the process time of each process calculated by the process time calculation unit 21. The process plan creation unit 31 creates a process plan, for example, as shown in Fig. 2, using input conditions such as the construction period and available days for work, and the process time of each process.

[0057] When the process time calculation unit 21 calculates the spare time, the process plan creation unit 31 may create the process plan taking into consideration not only the process time of each process but also the spare time.

[0058] The process plan creation unit 31 may determine the order of work locations in a pipeline where water pipe work is performed. For example, the process plan creation unit 31 may determine the order of work locations according to the degree of difficulty of the work.

[0059] As described above, the water pipe construction work process plan creation system 1 according to this embodiment creates a daily water pipe construction work process plan. The process plan creation system 1 has an information acquisition unit 11 that acquires water pipe related information related to at least one of the diameter, length, type, number, and arrangement of the water pipes W used in the water pipe construction work, a process time calculation unit 21 that calculates a process time including the work time of each process of the water pipe construction work based on the water pipe related information acquired by the information acquisition unit 11, and a process plan creation unit 31 that creates a process plan for at least a part of the water pipe construction work using the process time of each process calculated by the process time calculation unit 21.

[0060] With the above-mentioned configuration, the process time of each process of the daily water pipe construction work can be calculated based on the water pipe related information, and the calculated process time can be used to create a process plan for at least a part of the daily water pipe construction work. Therefore, the daily water pipe construction work process plan can be automatically and easily created.

[0061] Furthermore, the water pipe work process plan creation system 1 may create a monthly water pipe work process plan based on the created daily water pipe work process plan as shown in Fig. 3. Specifically, the water pipe work process plan creation system 1 may create a monthly water pipe work process as shown in Fig. 3 by integrating the created daily water pipe work process plans for the number of days.

[0062] The water pipe construction process plan creation system 1 may create only a daily water pipe construction process plan, or may create only a monthly water pipe construction process plan. The water pipe construction process plan creation system 1 may create an overall process plan including a weekly process plan, a monthly process plan, and a yearly process plan. The method of calculating the process time for each process in the water pipe construction process plan other than daily is the same as the method of calculating the process time for each process in the above-mentioned daily water pipe construction process plan.

[0063] In this embodiment, the information acquisition unit 11 acquires water pipe work related information related to water pipe work in addition to the water pipe related information. The process time calculation unit 21 calculates the process time using the water pipe related information and the water pipe work related information acquired by the information acquisition unit 11.

[0064] This allows the water pipe construction work schedule to be created using water pipe construction work-related information related to the water pipe construction work in addition to the water pipe-related information, thereby allowing the water pipe construction work schedule to be created with higher accuracy.

[0065] In this embodiment, the water pipe construction related information includes above-ground related information including information related to the aboveground location where the water pipe W will be buried, and underground related information including information related to the underground location where the water pipe W will be buried.

[0066] This makes it possible to calculate the time required for each process of water pipe construction work, taking into account aboveground-related information and underground-related information that have a significant impact on the water pipe construction work. Therefore, it is possible to create a process plan for water pipe construction work with higher accuracy.

[0067] In this embodiment, the ground-related information includes ground surroundings-related information related to the ground surroundings of the location where the water pipe W is buried, and road condition-related information related to the road conditions of the location where the water pipe W is buried.

[0068] This makes it possible to calculate the time required for each stage of water pipe construction work by taking into account ground surroundings-related information and road conditions-related information, which are among ground-related information that have a significant impact on water pipe construction work. Therefore, it is possible to create a more accurate process plan for water pipe construction work.

[0069] In this embodiment, the underground-related information includes information related to at least one of underground obstacles, road structure, soil quality, and groundwater.

[0070] This makes it possible to calculate the time required for each process of water pipe construction, taking into account information related to at least one of underground obstacles, road structure, soil quality, and groundwater, which have a significant impact on water pipe construction. This makes it possible to create a process plan for water pipe construction with higher accuracy.

[0071] In this embodiment, the process time calculation unit 21 may calculate the reserve time for each process of the water pipe construction work based on the water pipe related information and the water pipe construction related information. The process plan creation unit 31 may create a process plan for at least a part of the water pipe construction work, taking into account not only the process time of each process but also the reserve time.

[0072] This allows the creation of a water pipe construction schedule that takes into account risks such as when the schedule needs to be changed due to unexpected buried objects underground or when the schedule needs to be changed due to conditions above ground (such as when there are times when construction cannot be done at parking lots or store entrances), etc. This makes it possible to create a water pipe construction schedule with greater accuracy.

[0073] In this embodiment, the information acquisition unit 11 may acquire construction suspension related information related to dates and times when water pipe construction is not performed as the water pipe construction related information. The process plan creation unit 31 may create a process plan for at least a part of the water pipe construction using the construction suspension related information acquired by the information acquisition unit 11 and the process time of each process calculated by the process time calculation unit 21.

[0074] This makes it possible to create a schedule for water pipe construction work excluding periods or time periods when water pipe construction work is suspended, thereby making it possible to create a schedule for water pipe construction work with greater accuracy.

[0075] (How to create a process plan) Next, a process plan creation method executed by the process plan creation system 1 having the above-mentioned configuration will be described with reference to Fig. 11 and Fig. 12. Fig. 11 is a flowchart showing an outline of the process plan creation method. Fig. 12 is a flowchart showing an outline of a method of acquiring water pipe related information and water pipe work related information in the process plan creation method.

[0076] 11, first, the information acquisition unit 11 of the construction schedule creation system 1 acquires a construction period and available work dates (step S1). The construction period and available work dates may be input to the construction schedule creation system 1, for example, or the construction schedule creation system 1 may acquire the information from another system or storage device.

[0077] Next, in step S2, the information acquisition unit 11 acquires water pipe related information and water pipe construction related information. Specifically, the information acquisition unit 11 acquires water pipe related information and water pipe construction related information as shown in the flowchart of FIG.

[0078] First, in step SA1, the information acquisition unit 11 reads design data for the piping of a water pipe. The information acquisition unit 11 reads the design data, for example, from another system or a storage device. The design data is, for example, data related to at least one of the size (diameter, length), type, number, and arrangement of the water pipe obtained by a pipeline design of the water pipe. That is, the information acquisition unit 11 acquires water pipe-related information. The design data may include ground-related information around the pipeline of the water pipe.

[0079] Next, in step SA2, the plan control unit 15 selects a work range, which is the input range of the construction conditions in step SA3. The work range selected by the plan control unit 15 is input to the information acquisition unit 11. The selection of the work range may be performed by input to the information acquisition unit 11, or may be performed using a work range set in another system or storage device.

[0080] The work range may be the entire range of the pipeline where the water pipe construction work is performed, or may be only a part of the pipeline. The information acquisition unit 11 may select the work range by selecting a start point and an end point of the pipeline.

[0081] In the next step SA3, the information acquisition unit 11 acquires the construction conditions of the water pipe in the work area selected in step SA2. The construction conditions include information related to the water pipe construction. That is, the construction conditions include information related to the site conditions, aboveground related information, and underground related information.

[0082] The information related to the site conditions includes at least one of information regarding available working hours, available personnel, type and number of work machines to be used, whether parallel work can be performed, whether work machines can be used in parallel, transportation time for soil, water pipes, etc.

[0083] The ground-related information includes at least one of the following information: traffic information at the location where the water pipe construction work is to be performed, and if the location where the water pipe construction work is to be performed is a road, information regarding the width and number of lanes of the road, and information regarding the environment (houses, stores, etc.) in the vicinity of the location where the water pipe construction work is to be performed.

[0084] The underground related information includes information related to at least one of underground obstacles (underground structures such as cross pipes, other underground buried objects, etc.), road structure, soil quality, and groundwater. The underground related information may include information related to the type, size, location, etc. of underground obstacles. The underground related information may include information related to road structure such as the thickness and characteristics of the pavement and roadbed. The underground related information may include information related to the soil quality (sand, silt, clay, etc.) at the excavation location. The underground related information may include information related to the location and amount of groundwater. The underground related information may include information related to the need for retaining soil, the retaining soil method (sheet piles, cut beams, etc.), the retaining soil construction method (building in, driving in, etc.), and the range of the retaining soil.

[0085] In step SA4, the plan control unit 15 determines whether or not to use retaining soil and the extent to which the retaining soil will be implemented based on the underground-related information and the like acquired by the information acquisition unit 11. In detail, the plan control unit 15 determines whether or not to use retaining soil and the extent to which the retaining soil will be implemented based on information such as the underground soil quality and groundwater, for example. The information regarding the retaining soil determined by the plan control unit 15 is input to the information acquisition unit 11 as water pipe construction-related information.

[0086] In the next step SA5, the plan control unit 15 determines whether or not trial excavation should be performed and the trial excavation location based on the underground related information and the like acquired by the information acquisition unit 11. In detail, the plan control unit 15 determines whether or not trial excavation should be performed and the trial excavation location based on information such as underground obstacles. The information regarding trial excavation determined by the plan control unit 15 is input to the information acquisition unit 11 as water pipe construction related information. Thereafter, the process plan creation system 1 returns to the flowchart shown in FIG. 11 and performs the process of step S3.

[0087] It is to be noted that step SA4 does not necessarily have to be performed in the process planning method, and step SA5 does not necessarily have to be performed in the process planning method.

[0088] In step S3 of the flowchart shown in Fig. 11, the process time calculation unit 21 calculates the process time for each process of the water pipe construction based on the water pipe related information and the water pipe construction related information acquired in step S2. Specifically, the process time calculation unit 21 calculates the work time required to bury one water pipe based on the water pipe related information and the water pipe construction related information, for example. The method by which the process time calculation unit 21 calculates the work time may be any method.

[0089] In the next step S4, the process plan creation unit 31 creates daily and monthly process plans using the process times for each process calculated by the process time calculation unit 21 and the information such as the construction period and available days acquired by the information acquisition unit 11 in step S1. Specifically, the process plan creation unit 31 creates a process plan by combining the process times so that each day's process is completed in one day and the entire water pipe construction is completed by performing work on the available days within the construction period. At this time, the process plan creation unit 31 creates a process plan so that the work can proceed efficiently depending on the presence or absence of parallel work, the number of work machines, transportation time, etc.

[0090] Here, step S2 corresponds to an information acquisition step, step S3 corresponds to a process time calculation step, and step S4 corresponds to a process plan creation step.

[0091] The water pipe construction work process plan creation method according to the present embodiment is a method for creating a water pipe construction work process plan. The process plan creation method includes an information acquisition step of acquiring water pipe related information related to at least one of the diameter, length, type, number, and arrangement of water pipes used in the water pipe construction work, a process time calculation step of calculating a process time including a working time of each process of the water pipe construction work based on the water pipe related information acquired in the information acquisition step, and a process plan creation step of creating a process plan for at least a part of the water pipe construction work using the process time of each process calculated in the process time calculation step.

[0092] The above-mentioned method allows the process time of each process of water pipe construction to be calculated based on the water pipe related information, and the calculated process time can be used to create a process plan for at least a part of the water pipe construction. Therefore, the process plan for water pipe construction can be automatically and easily created.

[0093] (A program for creating a schedule for water pipe construction) The program in the embodiment of the present invention may be a program that causes a computer constituting the process plan creation system 1 to execute steps S1 to S4 shown in Fig. 11. The process plan creation system 1 and the process plan creation method in this embodiment can be realized by executing this program by the computer of the process plan creation system 1. In this case, the computer constituting the process plan creation system 1 may be a general-purpose computer or a dedicated computer. The computer is equipped with, for example, a CPU, and performs arithmetic processing by the CPU (Central Processing Unit).

[0094] In this embodiment, the data acquired by the process plan creation system 1 and the calculation results are stored in a storage device (not shown). When the process plan creation system 1 performs calculations using the data stored in the storage device, the process plan creation system 1 reads the data and performs calculation processing. The storage device is configured with a storage medium including a storage device such as a memory, a hard disk, etc.

[0095] The program for creating a process plan for water pipe construction according to the present embodiment is a program for creating a process plan for water pipe construction, which causes a computer to acquire water pipe-related information related to at least one of the diameter, length, type, number, and arrangement of water pipes W used in the water pipe construction, calculate process times including the work time of each process of the water pipe construction based on the acquired water pipe-related information, and create a process plan for at least a part of the water pipe construction using the calculated process times of each process.

[0096] With the above-mentioned configuration, the process time for each process of the water pipe construction work can be calculated based on the water pipe related information, and the calculated process time can be used to create a process plan for at least a part of the water pipe construction work. Therefore, the process plan for the water pipe construction work can be automatically and easily created.

[0097] (Modification) Next, a modified example of the process plan creation system 1 having the above-mentioned configuration will be described with reference to Fig. 13. Fig. 13 is a functional block diagram showing a schematic configuration of the process plan creation system 100 according to this modified example. The configuration of the process plan creation system 100 according to this modified example differs from the configuration of the process plan creation system 1 of the first embodiment in that the process time calculation unit 121 has a preliminary time correction unit 122. Therefore, in the following description, the same components as those in the first embodiment are denoted by the same reference numerals, and only the parts different from the first embodiment will be described.

[0098] The process time calculation unit 121 calculates the reserve time for each process of the water pipe construction work, and corrects the reserve time in accordance with the past performance of the water pipe construction work.

[0099] The reserve time correction unit 122 corrects the reserve time according to past results of the water pipe work. Specifically, the reserve time correction unit 122 corrects the reserve time of the water pipe work for which a process plan is to be made, using the results of parameters of the water pipe work related information, which differ for each water pipe work site. The reserve time correction unit 122 also corrects the reserve time, taking into consideration cases in which water pipe work cannot be performed due to seasonal weather, such as the rainy season or snowfall season. In this way, the reserve time correction unit 122 corrects the reserve time based on information on past results, including the conditions of the water pipe work site and the weather during past work periods. This can improve the calculation accuracy of the reserve time.

[0100] As described above, in this modified example, the process time calculation unit 121 has the spare time correction unit 122 that corrects the spare time for each process of water pipe construction based on past results.

[0101] This allows the reserve time for each process of water pipe construction to be calculated with high accuracy based on past results. For example, since parameters related to water pipe construction differ for each work site, the reserve time can be corrected according to the parameters to reflect past results in the reserve time. In addition, the reserve time can be calculated with higher accuracy by correcting the reserve time based on past weather data for the time of water pipe construction.

[0102] Therefore, the corrected spare time can be used to create a more accurate process plan for water pipe construction.

[0103] [Embodiment 2] 14 is a functional block diagram showing a schematic configuration of a process plan creation system 200 according to embodiment 2. The process plan creation system 200 according to embodiment 2 differs from the process plan creation system 1, 100 according to embodiment 1 in that the process plan is revised according to the progress of the water pipe construction work. Therefore, in the following description, the same components as those in embodiment 1 are denoted by the same reference numerals and the description is omitted, and only the parts different from embodiment 1 will be described.

[0104] The process plan creation system 200 includes an information acquisition unit 11 , a plan control unit 15 , a process time calculation unit 21 , a process plan creation unit 31 , a progress status related information acquisition unit 241 , and a process plan correction unit 242 .

[0105] The progress status related information acquisition unit 241 acquires progress status related information of the water pipe construction work. The progress status related information is information related to the progress status of the water pipe construction work, such as construction record data, schedule data, construction management data, etc. The progress status related information acquisition unit 241 may acquire the progress status related information from a construction information system (not shown) that manages construction information, for example, or may acquire the progress status related information by input.

[0106] The process plan correction unit 242 corrects the process plan created by the process plan creation unit 31, based on the progress status related information acquired by the progress status related information acquisition unit 241. The process plan correction unit 242 outputs the corrected process plan data.

[0107] Fig. 15 shows a flowchart of the process plan creation method executed by the process plan creation system 200 having the above-mentioned configuration. As shown in Fig. 15, steps S1 to S4 of the process plan creation method executed by the process plan creation system 200 are the same as steps S1 to S4 of the process plan creation method executed by the process plan creation system 1 of embodiment 1. Therefore, a description of steps S1 to S4 will be omitted.

[0108] After the process plan creation unit 31 creates a process plan in step S4, the progress status related information acquisition unit 241 acquires progress status related information in step S101. In the following step S102, the process plan correction unit 242 corrects the process plan based on the progress status related information. Thereafter, the process plan correction unit 242 outputs the corrected process plan.

[0109] In this embodiment, the process plan creation system 200 has a progress status related information acquisition unit 241 that acquires progress status related information related to the progress of water pipe construction work, and a process plan correction unit 242 that corrects the process plan created by the process plan creation unit 31 using the progress status related information acquired by the progress status related information acquisition unit 241.

[0110] This allows the water pipe construction work schedule to be revised according to the actual progress of the water pipe construction work. With the configuration of the construction work schedule creation system 200 of this embodiment, for example, when water pipe construction work cannot be carried out due to the influence of weather such as rain, the construction work schedule can be revised to make up for the delay in construction. Therefore, the water pipe construction work schedule can be created with higher accuracy according to the actual situation.

[0111] (Other embodiments) Although the embodiment of the present invention has been described above, the above-mentioned embodiment is merely an example for carrying out the present invention.

The process time calculation unit may calculate the reserve time for each process of the water pipe work based on the water pipe work related information.

[0117] In each of the above-described embodiments, the process plan creation system 1, 100, 200 creates and outputs a process plan for water pipe construction work to bury a water pipe underground. However, the process plan creation system may create a process plan for water pipe construction work that includes not only burying the water pipe but also burying a parallel pipe that is arranged in parallel to the water pipe.

[0118] In each of the above-described embodiments, the process plan creation system 1, 100, 200 creates a process plan for water pipe construction work. However, the process plan creation system may create documents to be submitted to the water utility, including a construction management plan, in addition to the process plan.

The process plan creation system may also automatically create a process schedule and daily construction report. The process plan creation system may also automatically create documents for after construction is completed, such as an implementation process schedule.

[0119] In each of the above-mentioned embodiments, the process plan creation system 1, 100, 200 creates a process plan for water pipe construction using an open-cut method that excavates the ground. However, the process plan creation system may also create a process plan for water pipe construction using a non-open-cut method that is used when piping water pipes in tunnels, etc. In this case, the process plan creation system creates a process plan based on a process suitable for the non-open-cut method for water pipe construction.

[0120] In the second embodiment, the process plan creation system 200 modifies the process plan for the water pipe construction work according to the actual progress of the water pipe construction work.

Such a recommendation may be made by the process plan creation system of the first embodiment. [Industrial Applicability]
