Description

  The present invention relates to a underground unit price integration system that integrates unit prices of construction work and materials (hereinafter referred to as underground unit price) in power line burying work underground.

  Conventionally, to calculate the unit price of underground cable, selection of pipe material and calculation of quantity based on the designed drawings, calculation of excavated soil by excavation area, calculation of asphalt amount if road, man-hour for construction work It was estimated by calculation.

  For example, when excavating a road, this work is calculated by multiplying the excavation amount in the construction section by the construction unit price. The amount of excavation was calculated by multiplying this by the length of the excavation section (section length). In addition, the material cost was calculated by multiplying the material unit price per unit length by the section length.

  However, the actual construction works are diversified, such as cutting around the planned excavation position, earth retaining work and residual soil treatment. For this reason, conventionally, the construction cost is estimated by setting the construction unit price in anticipation of the occurrence of these various constructions, and accumulating them.

  The method of adjusting the estimate by the construction unit price has caused a problem that the difference between the estimate and the actual construction content cannot be absorbed and the expected profit cannot be obtained. There is also a problem that the unit price is set excessively in order to ensure profits.

On the other hand, in order to calculate a construction estimate with high accuracy, a technique for strict profit management and cost management by inputting a construction cost, a profit rate, and the like has been proposed. (For example, see Patent Documents 1 and 2).

Then, it is selected whether the input is new data or the previous continuous input (S103 to S105). Next, when the main function is activated, the subject is input (S114), the construction summary is registered / corrected if necessary (S115), and the menu such as the pipe total is selected (S116). When each menu is activated, it accepts data input, performs predetermined arithmetic processing based on the input data, and outputs the arithmetic results (S127 to S135). Details will be described below.

[Design information registration process]
First, as a preparation stage, design information is stored by design information registration means 24 for each type of underground line construction. This design information defines the length, width, depth, thickness, etc. (collectively referred to as “dimensions”) that should be managed based on the construction details in the excavation section, and the dimension symbol (dimension identification information) ) To define the amount of work for each work item.
The types of construction may be divided into pipeline construction, lead-in construction, manhole construction, handhole construction, cable box interior construction, and the like.

  In the following, the design information will be described taking pipe construction as an example. FIG. 3 is an explanatory diagram of management items (dimensions to be managed) in pipeline construction.

This figure has shown the cross section with respect to the length direction of a pipeline construction area. Excavation width W, influence width W1, cloth excavation width W2, excavation depth H1: H2, pavement overall thickness T1, asphalt (As), concrete (Co) thickness ST1, etc. As shown, dimension symbols are defined, and data corresponding to each dimension symbol is input by a pipe integration function described later. Since the digging depth may vary in the length direction of the section, the digging depth start point is H1 and the digging depth end point is H2.
Furthermore, information on the relational expression is stored so that the volume (volume) of the following work items or a volume equivalent value capable of calculating the estimated amount can be calculated using the input dimension data.

(A) Pavement cutting worker LH1
・ When pavement restoration is “not done”, or when pavement restoration is “taken”, consideration of affected parts is “not considered”, and administrator instruction width is “0” LH1 = L * 2
・ When pavement restoration is “Yes”, affected area is considered “Both sides”, or when pavement restoration is “Yes”, and administrator instruction width is other than “0” LH1 = L * 4
・ When pavement restoration is “Yes”, the affected area is considered “one side”, and the administrator instruction width is “0” LH1 = L * 3
This pavement cutting work is stored as a volume equivalent value for calculating an estimated amount.

(B) Pavement plate crushing treatment ・ In the case of normal excavation HS1 = L * W
・ In the case of sheet pile advanced excavation HS2 = L * (W + W2 * 2)

(C) Drilling VK
・ In the case of normal excavation VK1 = L * W * ((H1 + H2) / 2−T1)
・ In the case of sheet pile advanced excavation VK2 = L * (W + W2 * 2) * (T2-T1) + L * (W + W2 * 2) * T2
+ L * W * ((H1 + H2) / 2−T2)
Here, the value of cloth moat width (one side) W2 at the time of sheet pile driving is 0.7, and the value of cloth moat depth T2 at the time of sheet pile driving is 0.8.

(D) Sandbed VST
VST = L * W

(E) Backfill VR
・ In the case of normal excavation VR1 = total excavation volume [VK] −VST * 0.05 under the above condition (c)
-Pipe volume [VKT]
-Sheet pile advanced excavation VR2 = L * (W + W2 * 2) * (T2-0.03)
+ L * (W + W2 * 2) * (T2-T1)
+ L * W * ((H1 + H2) / 2−T2)
-VST * 0.05-VKT
Here, in the case of backfilling using high-quality soil, the value of pipe volume * 4.8 is used. In the case of backfilling using reused soil, a value obtained by subtracting the number of backfilling using high-quality soil from the total backfilling amount is used.

(F) Residual soil treatment ZS = total excavation volume-backfill (reuse soil)

(G) Pipeline laying (pipeline)
KL = L * number of pipelines [NK]

(H) Install concrete guard plate NB = Calculated from material quantity

(I) Earth retaining work LSV = L * 2

(J) Lining board installation AH = INT (L + 0.99) * INT (W + W3 * 2 + 0.99)
Or the larger one of 2.0 Here, the distance W3 from the excavation line to the edge of the lining plate is 0.4 m.

(K) Covering plate opening / closing work AHK = AH * 3

(L) Water change NW = INT (VK / NJ + 0.99)
Only sections where the excavation depth is below the groundwater level are counted. The average daily drilling amount NJ is 20 m ³ .

(M) Other person's buried suspension protection NTB = Calculated from the input value of section data.

(N) Temporary pavement ・ In the case of normal excavation AKK1 = Pavement plate crushing disclaimer [HS1] (Used pavement component)
・ Sheet prior excavation AKK2 = Disclaimer for paving plate crushing treatment [HS2] (As 3 cm)
= Paving plate crushing treatment exemption [HS2] (for used paving components)

(O) Pavement restoration (excavation part)
Recorded only when pavement is restored.
・ Normal drilling AFK1 = L * W
-Sheet pile advanced excavation AFK2 = L * (W + W2 * 2)

(P) Pavement restoration (affected part)
Recorded only when pavement restoration is “Yes” and affected areas are considered “Both sides” or “One side”.
・ In the case of “both sides” considering the affected area AFE1 = L * W1 * 2
・ In the case of “one side” considering the affected area AFE2 = L * W1

(Q) Pavement restoration (administrator instruction department)
Only when the pavement restoration is “Yes” and the manager's specified range is> 0.
AFH1 = L * W4- (AFK + AFE)

In the above, the relational expression when calculating the work amount necessary for the estimation based on the dimension data of the pipe work was shown.
Information on this relational expression is stored in the design information DB 42. FIG. 8 is a data configuration example of the design information DB 42. Work items are defined for each construction type, and for each work item, estimation formula data is stored for each calculation condition.

Similarly, for other construction types such as lead-in construction (in the case of direct excavation, excavation slope), manhole construction, handhole construction, etc. Save expression information.
In addition, since the excavation method differs and the dimension data to be managed differ depending on the construction type, this is shown in FIGS.

For manhole construction, the excavation depth is divided into neck height and manhole (MH) height, and the lower part of MH is divided into basic crushed heat and leveled concrete thickness.
About the amount of backfilling, the amount excluding the volume of MH to be buried and the volume of foundation crushed stone and uniform concrete is the backfilling amount with respect to the total excavation volume.

  As for handhole (HH) construction, compared to MH, we will not take the cloth width, and we will manage the pavement cutting work only by the influence width and the manager instruction width.

[Unit price input / update processing]
The unit price input means 30 inputs or updates the unit price for the work amount of each work item. The entered / updated unit price information is stored in the unit price information DB 43. FIG. 9 is a data configuration example of the unit price information DB 43. Here, the unit price information is stored in association with the identification information of the work item.

  Next, the details of the main processes, namely, the pipe integration process, the cable integration process, and the design document creation process will be described with reference to FIGS.

[Pipe accumulation processing] (See Fig. 10)
The construction data input means 26 is activated to execute the pipe integration process (S201). In this function, first, submenus for setting calculation conditions, inputting section data, and outputting a form are selected (S202). In the calculation condition setting submenu, it is possible to set the type of pipe used, specify the pavement configuration, set the CAB section, and set the earth retaining work (S204).

  In the section data input submenu, section title input, work type selection, and construction time selection can be performed as new / continuous input processing (S207). In the selection of the type of work, the main line / supply pipeline, the service pipeline, manhole installation, handhole installation, and CAB construction can be selected. The construction time can be selected between daytime and nighttime.

  Each of these data is input (S208), and the input returns to the submenu upon completion of input (S209). In addition, correction, addition, and deletion of data input in the past can be performed (S210).

[Cable integration processing] (See Fig. 11)
A cable integration process is executed by the material data input means 27 (S301). First, sub-menus such as section data input and form output are selected (S302). When the section data input submenu is selected, data input for cable length and laying man-hours as new / continuous input processing, manholes / CABs, substations, mounting poles, roadside equipment, and service line construction are separated. Input is performed (S306, S307).

  In addition, the form output, such as data correction, is the same as the pipe integration function.

[Design document creation process] (See Fig. 12)
The construction cost calculation means 28 executes a design document creation process (S401). In this process, first, creation / modification of contract fee, creation / modification of material fee, or design document output submenu is selected (S402). When the sub-menu of contract fee and material fee is selected, next, the designation of pipe line, cable, security switchgear, transformer, pipe or cable pull-in is performed as the account item (S403). For cables, the cable length is calculated by adding the segment lengths, and the estimated cost of the cable is calculated by multiplying the unit price. The same applies to the pipeline (S404).

  In the calculation of the construction quantity, the construction type is divided into pipeline construction, lead-in construction, manhole construction, handhole construction, etc.

  Specifically, referring to the design information DB 42, the amount of work for each work item is calculated for each category using the dimension data, and the work amount of the estimation target as a whole is calculated by adding this work amount to a plurality of categories to be estimated. Calculate the amount. Thereafter, the estimated cost is calculated by multiplying the work amount by the unit price for each work item with reference to the unit price information DB 43. The calculation result is subjected to necessary editing (S405, S406) and output to the output unit 12 such as a printer or a display by the design document output means 29 (S407, S408).

[User interface]
Next, an input screen for smoothly and safely inputting the above complicated data will be described. This user interface is characterized by functional division and data input procedures.

  FIG. 13 shows an example of the main menu screen. Here, as the function division, the unit price data update may be made accessible to only a specific authorized person separately from the access authority of other functions.

(Pipe accumulation)
The input of pipe integration data is divided into setting of integration conditions and input of section data.
In addition, the setting of the integration condition can be further performed by specifying the type of pipe used, specifying the pavement configuration, setting the CAB section, and setting the earth retaining work.

  In the designation of the pipe type to be used, as shown in FIG. 14, the pipe type to be used in the construction (main pipe material, flexible pipe material) is designated according to usage such as power distribution, power transmission, and local government.

  In the designation of the pavement configuration, when a pavement other than the standard pavement configuration is used, the pavement configuration is registered on the screen shown in FIG. In this figure, the pavement quality is determined by the coating thickness t1, the As thickness t2, the Co thickness t3, and the influence width W, and the unit price is determined for each quality. Here, the designated pavement configuration is displayed in the pavement configuration selection window when the section data is input.

  The CAB section is set by registering the CAB type used in the construction. In FIG. 16, the CAB cross section can be specified for each type for each standard part, box part, and pipe part. For example, in the standard part, the number of cable racks, the number of bottom piping facilities, the bottom pipe support hardware, etc. can be set, and in the box part, the number of pipe lines, bottom pipe support hardware, upper pipe instruction band, construction You can specify the locality (or other company) or your company as the classification, or supply source as the material classification. In the pipeline section, the number of pipe holes is specified.

  The earth retaining work is set by registering the driving sheet pile used in this work. In FIG. 17, as for the earth retaining work, a sheet pile type, a sheet pile length, a minimum excavation width, and a construction method can be input. If the minimum excavation width does not meet the conditions when the excavation width of the section data is input, an error message is output.

Next, the section data input screen will be described.
As shown in FIG. 18, the section data is input by selecting a construction section, selecting a work type such as a main line and a supply pipeline, and a construction time such as day and night. In the work type selection, the work type can be selected by a selection window.

Hereinafter, the input of section data will be described by taking the section data input screen for pipe construction shown in FIG. 19 as an example.
Here, as the section data, basic data (section length, excavation width, excavation depth, etc.) related to the excavation work can be input. Also, the cable type can be input for each application. The construction type is input for each section divided into the construction sections, and basic data corresponding to each construction type such as a manhole or a handhole is input.

(Cable integration)
Next, cable data input processing will be described.
As cable data, cable length / laying man-hours, data in manholes / CAB, substation (CB, tunnel) data, column data, roadside equipment data, and service line construction data can be input.

As shown in FIG. 20, the cable length and man-hours are set by inputting data necessary for calculating the cable length and man-hours for each laying configuration.
For manhole / CAB data, input data such as hardware and cable accessories used in manholes, etc. on the input screens shown in FIGS.

As for the service line construction data, data such as the size and length of the service cable and the size and length of the shop side defeat are input on the input screen of FIG.

By clicking on account items such as pipelines, cables, security switchgears, transformers, and pull-in work (pipelines, cables), the contract amount is read and the unit price for each work item is multiplied. Thus, an estimate of the construction contract cost is calculated.
Similarly, the material cost is specified for each account item, the material quantity summary data is read, and the design document breakdown is automatically generated by multiplying it with the material unit price.

  The data of the estimated design document file 44 is output as a design breakdown. FIG. 31 is a screen example of a design breakdown. Here, in the name column, the work item name to be estimated is displayed, and a column for units, quantity, unit price, amount of money, etc. is provided for each item, and the calculation result by the construction cost calculation means 28 is displayed in each upper row. The lower part can be corrected by manual input.

It should be noted that the form output format may be settable as necessary, such as for all sections or for each specified section.
As work progress management, the current input section status is displayed as shown in FIG. 32, and the design progress status for each section is displayed as shown in FIG.

  According to this embodiment, the construction of underground lines is classified into a plurality of construction types, the basic items necessary for each construction type are specified, and other items are calculated based on the data of the basic items. Therefore, it is possible to estimate with high accuracy with a small amount of data input. Also, man-hour management is divided into work and materials, construction type is set for each section, basic information necessary for each construction type is defined for section section, and this is the work volume or volume over the section length. Calculate the value and multiply this by the unit price for each work item to estimate the work man-hours. For materials, use the section length to determine the cable length and multiply the unit price for each cable type. Therefore, it is possible to calculate a highly accurate estimate with a small number of data items.

When a series of data input is completed, the construction cost calculation means 28 is activated, and an estimate is calculated using the input data. This calculation result is stored in the estimated design document file 44.

  The estimated design document is created for each trader using the unit price set by the trader. It should be noted that the trader may input regional information serving as a service territory and create a trader that supports this region.

[Quote design document transmission process]
The contents stored in the estimated design document file 44 are transmitted to the terminal 2 of the corresponding user. The estimated design documents are numbered in ascending order of price, for example, as a predetermined priority.

[Construction order acceptance processing]
Although not shown in FIG. 34, a construction order receiving means may be provided by specifying an estimated amount so as to receive a construction order from the user.

  In this order, the user designates a quote design document and places an order in order to clarify which quote the order is for.

[Construction instruction output processing]
A construction instruction is output to the contractor of the estimated design document specified by the user.

  According to the present embodiment, instead of performing an estimate by changing the unit price for an actually complicated construction method, the man-hour is automatically calculated in association with the work item based on the basic work, Since the estimate is calculated by multiplying the unit price for the work, it is possible to estimate with high accuracy.

  In addition, the user can confirm the estimated design document issued in a predetermined priority order and place an order for the construction. The construction contractor can change the estimated amount by adjusting the unit price of each construction item. Can do. For this reason, it is easier to manage profits compared to directly changing the total estimated amount, and it is possible to avoid a situation in which a loss occurs after receiving an order.

  It is apparent that the present invention can be implemented with various modifications without departing from the spirit of the present invention. For example, when the estimated design document is completed by the construction cost calculation means 28 and saved in the estimated design document file 44, the server of the supplier in charge of the estimated design document is notified, and the supplier confirms the estimated amount, If it is determined whether the order can be received and the order cannot be received, the estimated design document may be deleted or the like may be declined.

  In addition, when the user enters the pipeline construction data and material data, a photograph of the construction site is also attached, and after the estimate design document is completed, the corresponding contractor can check the photograph and change the estimated amount You may do it.
