Description

The present invention relates to a concrete driving plan making device and a driving plan making method.

Usually, the concrete construction builder manually creates a driving plan and drives concrete according to the plan. When the object to be constructed is a tall member, concrete is driven into several layers (for example, one layer is about several tens of cm), so the driving plan is sometimes called a "stacking plan". be. In concrete work, the interval of time for concrete to be piled up (laying time interval) is an important management item. If it takes a long time to stack, initial defects such as cold joints will occur and the specified quality cannot be ensured.

Conventionally, for example, the following techniques have been proposed as a technique for managing the stacking time interval in concrete works.
Patent Document 1 describes that by acquiring information on the shape of the stacked surface by using a shape sensor arranged above the formwork, it is possible to confirm the concrete driving situation in a place where it is difficult to see by the formwork. Has been done.
Further, Patent Document 2 describes that an image taken from the upper side of a concrete placing site is subdivided into a mesh shape, and the mesh is color-coded for each stage according to the elapsed time from the completion of the placing. This makes it possible to visually grasp the stacking time interval.

However, since the techniques described in Patent Documents 1 and 2 are all techniques for managing the stacking time interval during concrete driving, it is still necessary to manually create a driving plan. was there. Therefore, when the shape of the construction object is complicated, there is a problem that a lot of time is spent on creating a driving plan. Further, since the judgment as to whether or not the created driving plan is optimal is largely at the discretion of the builder, there is a problem that it is difficult to objectively evaluate whether or not the driving plan is optimal.

From such a viewpoint, the present invention provides a driving plan making device and a driving plan making method capable of making a suitable driving plan for concrete.

The driving plan making device according to the present invention is a driving plan making device for making a driving plan in concrete placing. The driving plan is a driving order in units of construction blocks in which the order in which concrete is driven into the construction blocks obtained by dividing the construction target is set.
This driving plan creating device determines a block group setting unit that sequentially sets a candidate block group, which is a group of construction blocks to be continuously driven, with respect to the construction target, and a driving order in the candidate block group. It is provided with an in-group order determination unit.
The candidate block group is composed of a stacking block adjacent to the block of interest, which is the construction block that serves as a reference for the candidate block group, and an expansion block located around the stacking block.
When the driving order in the previous candidate block group is determined, the block group setting unit has not completed the driving to the adjacent construction block from the already driven construction blocks and the driving completion time. Selects the earliest driven construction block, and newly sets the candidate block group with the selected construction block as the new attention block.

The driving plan making method according to the present invention is a driving plan making method for making a driving plan in concrete placing. The driving plan is a driving order in units of construction blocks in which the order in which concrete is driven into the construction blocks obtained by dividing the construction target is set.
In this driving plan creation method, a block group setting step for sequentially setting a candidate block group, which is a group of construction blocks to be continuously driven, with respect to the construction target object, and a driving order within the candidate block group are determined. It has an order determination step within the group. By repeatedly executing the block group setting step and the intra-group order determination step, the driving order of the construction blocks constituting the construction target is determined.
The candidate block group is composed of a stacking block adjacent to the block of interest, which is the construction block that serves as a reference for the candidate block group, and an expansion block located around the stacking block.
In the block group setting step, when the driving order in the previous candidate block group is determined, the driving to the adjacent construction block from the already driven construction blocks is not completed and the driving completion time. Selects the earliest driven construction block, and newly sets the candidate block group with the selected construction block as the new attention block.

The expansion block is the construction block one step below the block of interest, and is preferably located outside the stacking block.

In the driving plan creating device and the driving plan creating method according to the present invention, the candidate block group is set so that the overlapping blocks of the blocks of interest are completed at an early stage. That is, the construction blocks that are not directly related to the stacking of the blocks of interest are also included in the candidate block group so that the driving constraint conditions of the stacking blocks are set earlier. Therefore, it is effective in shortening the maximum stacking time as compared with the case where only the stacking block for the block of interest is used as the candidate block. As a result, a suitable concrete driving plan can be created.

According to the present invention, it is possible to provide a driving plan making device and a driving plan making method capable of making a suitable driving plan for concrete.

<Configuration of driving plan creation device according to the embodiment>
With reference to FIG. 1, the configuration of the driving plan creating device 100 according to the embodiment will be described. FIG. 1 is a schematic configuration diagram of a driving plan creating device 100 according to an embodiment. The driving plan creating device 100 is a device for creating a driving plan in concrete placing. The driving plan creating device 100 can be used in various situations in which concrete is placed, and the type, shape, size of the object to be constructed, the method of placing concrete, and the like are not particularly limited. The driving plan shows the order in which concrete is driven, and for example, the information for identifying a part (for example, a block) of a construction target is associated with the order in which concrete is driven.

With reference to FIG. 2, the construction object to be concreted will be described. FIG. 2 is an example of a construction target for which concrete work is to be performed, (a) is an image diagram of a state in which the construction of the concrete structure A, which is the construction target, is completed, and (b) is a front view of the concrete structure A. It shows the state seen from. In the present embodiment, as shown in FIG. 2A, it is assumed that the concrete structure A spreads in the lateral, depth, and height directions as the construction target, and the driving plan creating device 100 is the concrete structure A. Create a driving plan for. The concrete structure A has an outstanding length in any of the horizontal, depth, and height directions (a structure having a long shape such as a pillar or a beam), or any of the horizontal, depth, and height. It may be a structure having an outstanding length in two directions (a planar structure such as a wall or a floor).

The concrete structure A is divided into a plurality of areas, and the smallest divided area is referred to as "construction block B". The construction block B is an area of the smallest unit for managing construction. The construction block B may be an area where the boundary with the adjacent construction block B is physically determined by the formwork, wire mesh, joint material, etc., or the boundary with the adjacent construction block B is physically determined. It may be a virtual area that has not been created. In the following, when a specific construction block B is shown and described, it may be referred to as “construction block B (k, l, m)”. "K, l, m" is identification information for identifying the construction block B. Here, "k" indicates the arrangement order in the horizontal direction, "l" indicates the arrangement order in the depth direction, and "m". "Indicates the order in the height direction. The size of one construction block B (k, l, m) can be determined, for example, by the construction conditions for concrete placing (particularly, the performance of the pump truck used for concrete driving).

The driving plan creating device 100 shown in FIG. 1 creates a driving plan of the concrete structure A by simulation using a virtual three-dimensional space. In the simulation of the driving plan, the driving plan is created using the construction model C (see FIG. 1), which is an abstraction (modeling) of the concrete structure A. The construction model C is divided corresponding to the construction block B (k, l, m) like the concrete structure A.

As shown in FIG. 1, the driving plan creating device 100 according to the embodiment includes a storage unit 30 and a control unit 40. The driving plan creating device 100 is, for example, connected to a personal computer (PC: Personal Computer) operated by a person in charge of creating a driving plan (hereinafter referred to as “creator”) or the personal computer so as to be able to communicate with the personal computer. It is an application server. The creator here is, for example, a builder of concrete work.

The storage unit 30 is composed of a storage medium such as a RAM (Random Access Memory), a ROM (Read Only Memory), an HDD (Hard Disk Drive), and a flash memory. The control unit 40 is realized by a program execution process by a CPU (Central Processing Unit), a dedicated circuit, or the like. When the control unit 40 is realized by the program execution process, the storage unit 30 stores a program for realizing the function of the control unit 40. The driving plan creating device 100 may acquire information stored in the storage unit 30 from an external storage means (not shown) as needed.

The storage unit 30 stores information necessary for creating a driving plan (here, driving condition information 31 and construction model C). The driving condition information 31 includes information on the performance of the pump included in the concrete pump truck, information on the stacking time interval, and the like. Further, when concrete is driven by using a plurality of concrete pump trucks, the driving condition information 31 includes the number of driving ports for driving concrete and the like. The construction model C is an abstraction (modeling) of the construction object. The construction model C is divided corresponding to the construction block B (k, l, m) like the construction target. The positional relationship and size of each construction block B (k, l, m) are set in the construction model C.

The control unit 40 mainly includes a condition setting unit 41, a driving order creating unit 42, and an order evaluation unit 45. The functions of the control unit 40 shown in FIG. 1 are divided for convenience of explanation, and the method of dividing the functions is only an example of the present invention.

The condition setting unit 41 accepts registration of the driving condition information 31 and the construction model C, and stores these information in the storage unit 30.

The driving order creation unit 42 creates a driving plan using the construction model C. The driving order creating unit 42 includes a block group setting unit 43 and an in-group order determining unit 44.
The block group setting unit 43 sequentially sets the candidate block group Q (see FIG. 4), which is a group of construction blocks B to be continuously driven, with respect to the construction model C (construction object).
The group in-group order determination unit 44 determines the driving order in the candidate block group Q set for the construction model C (construction object).

FIG. 4 shows an example of the candidate block group Q. 4A and 4B are views for explaining the candidate block group Q, FIG. 4A is a perspective view of the candidate block group Q, and FIG. 4B is a plan view of the candidate block group Q. The candidate block group Q shown in FIG. 4 is defined by the geometrical positional relationship around the construction block Ba which is the reference of the candidate block group Q. In the following, the construction block Ba that is the reference of the candidate block group Q may be expressed as “focused block Ba”. For example, at the time of setting the candidate block group Q, the block group setting unit 43 pays attention to the already driven construction block B in which at least one of the adjacent construction blocks Ba has not been driven and the driving completion time is the earliest. Select as block Ba.

The stacking of the construction block B will be described with reference to FIG. FIG. 3 is a diagram for explaining the overlapping of the construction blocks B. As shown in FIG. 3, in order to complete the stacking of the block Ba of interest, the construction block Bb1 located in front of the block Ba of interest, the construction block Ba2 located behind, the construction block Ba3 located on the left, and the construction block Ba3 on the right. It is necessary to drive in all of the construction block Ba4 located and the construction block Ba5 located directly above. Since it cannot be placed in the air, it is assumed that there is another construction block B (or a base, etc.) directly under the focus block Ba, and the construction block B directly under the focus block Ba is not a problem here. I will decide. In the following description, these construction blocks Bb1 to Bb5 may be referred to as "overlapping blocks Bb" for the block Ba of interest. In other words, the block group setting unit 43 has not completed the stacking (the driving of any of the stacking blocks Bb has not been completed), and the driving completion time is the earliest in the construction block B. Is selected as the block Ba of interest.

As shown in FIG. 4, the candidate block group Q in the present embodiment is composed of a stacking block Bb adjacent to the block Ba of interest and an expansion block Bc located around the lower layer of the stacking block Bb. In this embodiment, the block Ba itself of interest, the block Ba of interest, and the construction block B directly under the overlapping blocks Bb1 to Bb4 are not included in the candidate block group Q. This is because these construction blocks B are premised on the fact that the driving has already been completed due to the constraints of the driving described later. The construction block B directly under the overlapping blocks Bb1 to Bb4 may be included in the candidate block group Q. The candidate block group Q in this embodiment is composed of five overlapping blocks Bb and eight extended blocks Bc. The arrangement of the expansion block Bc shown in FIG. 5 is merely an example, and other arrangements can be used. When the construction block Ba constituting the candidate block group Q without distinguishing between the overlapping block Bb and the expansion block Bc is described, it may be referred to as "candidate block P". That is, the candidate block group Q in this embodiment is composed of thirteen candidate blocks P.

When only the stacking block Bb (5 blocks in FIG. 4) with respect to the focus block Ba is set as the candidate block P, the shortest stacking of the focus block Ba is aimed at. However, with such a method of setting the candidate block P, the maximum stacking time may not necessarily be shortened when the driving order of all the construction blocks B is determined. Therefore, in the present embodiment, as shown in FIG. 4, the focus block is set so that the stacking block Bb of the focus block Ba is completed in the early stage, that is, the drive constraint condition of the stack block Bb is set earlier. The candidate block P is expanded by adding a construction block B (expansion block Bc) that is not directly related to the stacking of Ba (13 blocks in total with "5 + 8"). The eight added expansion blocks Bc cause noise with respect to the shortest stacking of the block Ba of interest, but are effective in shortening the maximum stacking time.

The group order determination unit 44 determines the driving order in the candidate block group Q. The method for determining the order by the group order determining unit 44 is not particularly limited, and various methods can be used. The group in-group order determination unit 44 may determine the driving order of the construction block B according to a determined rule, or may randomly determine the driving order of the construction block B. Further, the in-group order determination unit 44 has a function of determining whether or not the driving of the construction block B conforms to the preset constraint conditions. The driving constraint may be arbitrary, and the content is not limited. The group order determination unit 44 determines, for example, whether or not the construction block B can be driven.

The driving order creation unit 42 searches for the driving order until the driving of all the construction blocks B is completed, for example, as follows.
(1) Select the block Ba of interest according to the driving completion time.
(2) One place is selected from the candidate blocks P for which the driving is not completed, and it is determined whether or not the driving constraint condition is satisfied. If it is possible to drive in, the selected construction block B is considered to have been driven in.
(3) The operation of the step (2) is sequentially repeated until all the candidate blocks P in the candidate block group Q have been driven.
(4) When the input of all the candidate blocks P is completed, the next block of interest, Ba, is searched for, and the processes of steps (2) and (3) are performed. That is, the process does not proceed to the processing of the next block Ba of interest until the input of the candidate block group Q is completed.
Here, in the present embodiment, as a driving constraint condition, it is assumed that the driving cannot be performed in the shape of two steps protruding in the height direction. For example, in order to drive the stacking block Bb5 directly above the focus block Ba in FIG. 3, the focus block Ba in FIG. 3 and the stacking blocks Bb1 to Bb4 on the front, back, left, and right must be driven.

The order evaluation unit 45 shown in FIG. 1 evaluates the driving order created by the driving order creating unit 42. The method for evaluating the driving order is not particularly limited, and various methods can be used. The order evaluation unit 45 evaluates the driving order by, for example, the stacking time. In this embodiment, a calculation method of an interconnected neural network is applied in order to simply express the evaluation of the overlay time.

The evaluation of the overlay time using the calculation method of the interconnected neural network will be described. First, the assumed driving range is divided into several construction blocks (in the following description, they may be simply referred to as "blocks"). The order of driving the construction blocks may be any order, starting from anywhere, as long as there are no geometric restrictions. When the construction block is represented by "○ (white circle)" and the path is represented by a line, for example, in the case of three construction blocks, an interconnected neural network composed of three units as shown in FIG. It becomes. FIG. 5 is an image diagram of an interconnected neural network. Candidate routes are possible between all construction blocks that combine the two, and can be oriented in both directions. However, each construction block passes only once and can only be driven into one construction block at a time (when there is only one driving port).

As shown in FIG. 6, when the interconnected neural network is represented by a matrix-like hierarchical network of blocks and orders, it becomes a Hopfield type neural network. FIG. 6 is an image diagram of a Hopfield type neural network. Even in this matrix-like network, the construction blocks are connected to each other, and the flow of information can be regarded as the same as the original interconnected neural network. “○ (white circle)” in FIG. 6 represents an information processing unit called a unit. Unit is a term used in neural networks and is commonly used as the name of a function that receives the output of another unit and returns (outputs) some value (eg, "-1 to + 1"). There are the same number of units (3 blocks) corresponding to the construction blocks in each driving order. Since all construction blocks are driven in, the number of units will be the same in both vertical and horizontal directions (imax = jmax). In the figure, each driving sequence is called a layer. In this network, units in adjacent layers are connected, but units in the same layer and units in discontinuous layers are not connected. In the present embodiment, a case where the stacking time is expressed by using such a matrix will be described.

The formulation will be described below. As shown in FIG. 7, the block number "i" is taken vertically and the driving order "j" is taken horizontally, and a matrix is created as described above. This matrix is a hierarchical network in which the number of units is the same for each layer (units are prepared for the number of blocks in the vertical direction, and layers are prepared for the number of blocks in the horizontal direction), and the flow of information is limited from left to right. Is.

_{The output of the unit outputs "1 (x ij} = 1)" when the block with the corresponding block number is typed, and outputs "0 (x _ij = 0)" when the block with the corresponding block number is not typed. The weight between the units is the time required to drive the block corresponding to the output side unit "i (j-1)" (w _{i (j-1) → i (j)} = w _{i (j-1)} ). ..
The output of each unit in the previous layer is multiplied by the weight of the path between each unit and the unit of interest, and the total sum is calculated sequentially from the start of driving. The driving start time and the driving completion time of each construction block are expressed by the formulas (1) and (2) depending on the depth of the layer to be summed.

The stacking time interval is evaluated by the equation (3) as the difference between the driving completion time of the block of interest and the driving completion time of the stacking block. Here, as shown in FIG. 8, the formula (formula) is used as an index for discriminating between the construction blocks (stacking blocks) and the construction blocks that are not stacking with respect to the block of interest, based on the geometrical connectivity of the blocks. 4) was introduced. The maximum number of overlapping blocks for one block of interest is 5 blocks. Here, the target block is a construction block of the other party that is paired with the block of interest and calculates the stacking time.

<About the method of creating a driving plan according to an embodiment of the present invention>
A method of creating a driving plan using the driving plan creating device 100 according to the embodiment will be described with reference to FIG. 9 (see FIGS. 1 to 8 as appropriate). FIG. 9 is an example of a flowchart showing a method of creating a driving plan according to an embodiment. The driving plan is, for example, a driving order in units of construction blocks B in which the order in which concrete is driven into the construction blocks B in which the construction target is divided is set.

First, the creator sets the construction conditions, the construction model C that abstracts the concrete structure A, and the like in the driving plan creation device 100 via the condition setting unit 41 (step S101). The condition setting unit 41 may calculate these information without relying on the input operation of the creator or from other information input by the creator.

For example, the creator arranges a virtual block D (k, l, m), which is an abstraction of the construction block B (k, l, m), on a three-dimensional virtual space. Specifically, the virtual block D (k, l, m) is set as the coordinate value (X, Y, Z) of the Cartesian coordinate system in which the position of the construction block B (k, l, m) is set in the three-dimensional virtual space. ). Here, "X" corresponds to, for example, the lateral position of the construction block B (k, l, m), and "Y" corresponds to, for example, the depth direction of the construction block B (k, l, m). Corresponding to the position, "Z" corresponds to the position in the height direction of the construction block B (k, l, m), for example. As a result, the relative positional relationship of the construction block B (k, l, m) is reproduced in the three-dimensional virtual space by the coordinate values set in the virtual block D (k, l, m). In the following description, the construction block B is an abstracted virtual block D.

Further, the creator sets, for example, the time required to create one construction block B (k, l, m) (that is, the time required to drive one construction block B (k, l, m)). do. This time may be calculated from, for example, the size of the construction block B (k, l, m) and the pump performance.
In addition, the creator sets, for example, the number of driving ports for driving concrete (corresponding to the number of pump cars when driving concrete using a pump car).
Further, the creator sets, for example, the first construction block B (start block) to start driving. The creator arbitrarily sets one of the construction blocks B in contact with the ground (that is, the construction block B that does not drive into the air) as the start block. If there are a plurality of driving openings, a start block is set according to the number of holes.

Next, the creator instructs the driving plan creating device 100 to start the calculation of the driving order. As a result, the driving plan creating device 100 executes the processes after step S102. The driving plan creating device 100 may start the calculation of the driving order as soon as the setting in step S101 is completed.

The driving order creation unit 42 executes driving of the first construction block B (starting block) set in step S101 (step S102). Specifically, the driving order creation unit 42 drives the start block by, for example, setting information indicating that the order in which concrete is driven is the first for the first construction block B (start block). To finish. As a result, the driving of the construction block B (starting block) is completed.

Next, the block group setting unit 43 searches for the block of interest Ba (see FIG. 4) (step S103). The block Ba of interest is the construction block B (the block that has already been driven) in which the driving is completed, and the stacking is not completed and the driving completion time is the earliest. The incomplete stacking is a state in which at least one of the construction blocks B adjacent to the construction block B for which the driving has been completed has not been driven. That is, when all the construction blocks B adjacent to the construction block B have been driven, the stacking of the construction block B is completed. The block group setting unit 43 selects the construction block B that meets the above-mentioned conditions as the block Ba of interest.

When there is a block Ba of interest that can be selected and one construction block B is selected as the block Ba of interest (“Yes” in step S104), the group order determination unit 44 repeats the processes of steps S105 to S110 and is a candidate. The order of driving the construction block B (that is, the candidate block P (see FIG. 4)) included in the block group Q (see FIG. 4) is determined. The process of determining the driving order of the candidate blocks P shown in FIG. 9 is merely an example, and the process of determining the driving order of the candidate blocks P is not limited to that described here.

The group order determination unit 44 searches for the candidate block P (see FIG. 4) to be input next (step S105). The group order determination unit 44 selects one place from the untyped candidate blocks P. The method of selecting the candidate block P is not particularly limited. When there is a candidate block P that can be selected (“Yes” in step S106), the group order determination unit 44 determines whether or not the selected candidate block P meets the driving constraint condition (step S107).

When the driving constraint condition is not met (“No” in step S107), the group order determination unit 44 searches for another candidate block P (step S109), and newly selects the searched other candidate block P. (Step S105). On the other hand, when the driving constraint condition is satisfied (“Yes” in step S107), the group in-group order determining unit 44 sets the information indicating the order in which the concrete is driven, and makes the selected candidate block P already driven. (Step S108). After that, the group order determination unit 44 searches for the next candidate block P (step S110), and newly selects the next candidate block P that has been searched (step S105).

When there is no candidate block P that can be selected in the candidate block group Q (including when it disappears) (“No” in step S106), the block group setting unit 43 selects the next focus block Ba and a new focus block. The process proceeds to the process in Ba (step S111). Specifically, the block group setting unit 43 searches for a new block of interest Ba (see FIG. 4) (step S103). Then, the group intragroup order determination unit 44 repeats the processes of steps S105 to S110 to determine the driving order of the candidate blocks P included in the candidate block group Q (see FIG. 4) based on the newly selected attention block Ba. do.

When there is no selectable block Ba of interest (including when it disappears) (“No” in step S104), the driving order of all the construction blocks B is determined, so that the order evaluation unit 45 creates the driving order. The maximum stacking time in is calculated (step S112). The creator decides whether to recreate the typing order based on the calculated maximum stacking time. For example, if the maximum stacking time is within the permissible range, the creator will perform the construction in the created driving order, and if it is not within the permissible range, change the construction conditions, etc. Create the driving order again. The allowable range of the maximum stacking time is the time during which cold joints do not occur, for example, the time that does not exceed the allowable stacking time interval described in the "Concrete Standard Specification" issued by the Japan Society of Civil Engineers. be.

As described above, as shown in FIG. 4, the driving plan creating device 100 according to the embodiment sets the candidate block group Q so that the overlapping block Bb of the block Ba of interest completes the driving at an early stage. That is, the construction block B (expansion block Bc) that is not directly related to the stacking of the block Ba of interest is also included in the candidate block group Q so that the driving constraint conditions of the stacking block Bb are set earlier. Therefore, it is effective in shortening the maximum stacking time as compared with the case where only the stacking block Bb (5 blocks in FIG. 4) for the target block Ba is used as the candidate block P. As a result, a suitable concrete driving plan can be created.

With reference to FIGS. 10 and 11, the effect of the driving plan creating device 100 according to the embodiment is supplemented. The inventor has a case where the candidate block P is not expanded (when the candidate block group Q is composed of only the overlapping blocks Bb) and a case where the candidate block P is expanded (the candidate block group Q is the overlapping block Bb and the expansion block Bc). The simulations were performed with and, respectively, and the results were compared and examined. In the simulation, it was assumed that a structure composed of wall slabs (see FIG. 10) is driven into three layers.

10A and 10B are schematic views of the structure used in the simulation, FIG. 10A shows the structure of the first layer, FIG. 10B shows the structure of the second layer, and FIG. 10C shows the structure of the second layer. ) Shows the structure of the third layer. The quadrangle in FIG. 10 is each construction block B, and the numbers in the quadrangle indicate the block numbers. Since it is not possible to drive in the air, the 21 blocks of the first layer shown in FIG. 10A are candidates for the start block in the simulation. In the first layer and the second layer, there are four regions in which driving is not performed.

The simulation results will be described with reference to FIG. 11A and 11B are diagrams for explaining the simulation results, FIG. 11A shows the simulation results when the candidate block P is not expanded, and FIG. 11B shows the simulation results when the candidate block P is expanded. The simulation results are shown.

11 (a) and 11 (b) both correspond to the structure of the first layer, and the numbers in the quadrangle indicate the maximum stacking time when the driving is started from the construction block B. For example, when the candidate block P in FIG. 11A is not expanded, the maximum stacking time is “120 minutes” when the driving is started from the construction block B having the block number “1”, and the block number “2”. The maximum stacking time is "130 minutes" when the driving is started from the construction block B of. Here, when the candidate block P shown in FIG. 11A is not expanded, the average maximum stacking time when the driving is started from each construction block B is “153.3 minutes”. On the other hand, when the candidate block P shown in FIG. 11B was expanded, the average maximum stacking time when driving was started from each construction block B was "148.1 minutes".

As a result of comparing and verifying FIGS. 11 (a) and 11 (b), when the candidate block P shown in FIG. 11 (b) is expanded, the maximum stacking time is not necessarily shortened, but the driving is performed from each construction block B. The average value of the maximum stacking time at the start of is kept short. Further, when the candidate block P shown in FIG. 11B is expanded, the maximum stacking time tends to decrease when the hitting starts from the vicinity of the center (that is, the peak of the maximum stacking time tends to be suppressed). be). For example, when the driving is started from the construction block B having the block number “11”, the maximum stacking time when the candidate block P shown in FIG. 11A is not expanded is “220 minutes”. , The maximum stacking time when the candidate block P shown in FIG. 11B was expanded was "200 minutes".

Although the embodiments of the present invention have been described above, the present invention is not limited to this, and can be carried out without changing the gist of the claims.
