Description

The present invention relates to a concrete pouring plan creation device and a concrete pouring plan creation method.

Usually, a concrete contractor manually creates a pouring plan and pours concrete in accordance with the plan. When the object to be constructed is a tall member, concrete is poured in several layers (for example, each layer is about several tens of centimeters), so the pouring plan is sometimes called a "layered pouring plan." be. In concrete work, the time interval between pouring concrete (overlap time interval) is an important control item. If it takes time to repeat the hammering, initial defects such as cold joints may occur, making it impossible to maintain the desired quality.

Conventionally, for example, the following techniques have been proposed as techniques for managing pouring time intervals in concrete construction.
Patent Document 1 describes that the state of concrete placement in places that are difficult to see due to the formwork can be confirmed by acquiring information regarding the shape of the overlapping surface using a shape sensor placed above the formwork. has been done.
Further, Patent Document 2 describes that an image taken from above at a concrete pouring site is divided into meshes, and the meshes are color-coded for each stage according to the elapsed time from the completion of pouring. This makes it possible to visually grasp the overlapping time interval.

Japanese Patent Application Publication No. 2014-114638 JP2011-202383A

However, the techniques described in Patent Documents 1 and 2 are techniques for managing the pouring time interval while concrete is being poured, so it is still necessary to manually create a pouring plan. was there. Therefore, when the shape of the object to be constructed is complex, there is a problem in that it takes a lot of time to create a driving plan. Furthermore, since the decision as to whether the created driving plan is optimal depends largely on the discretion of the builder, there is a problem in that it is difficult to objectively evaluate whether the driving plan is optimal.

From this viewpoint, the present invention provides a pouring plan creation device and a pouring plan creation method that can create a suitable concrete pouring plan.

A pouring plan creating device according to the present invention is a pouring plan creating device that creates a pouring plan for concrete pouring. The pouring plan is a pouring order for each construction block, which sets the order in which concrete is poured into construction blocks into which the construction target is divided.
This driving plan creation device includes a block group setting unit that sequentially sets a candidate block group, which is a group of construction blocks to be successively driven, for the construction target, and a block group setting unit that determines the driving order within the candidate block group. and an intra-group order determining unit.
The candidate block group is composed of a stacked block adjacent to the block of interest, which is the construction block serving as a reference for the candidate block group, and an expansion block located around the stacked block.
The block group setting unit determines, at the time when the driving order in the previous candidate block group is determined, that the driving for the adjacent construction block among the already driven construction blocks is incomplete and the driving completion time. selects the construction block that has already been driven in the earliest, and sets the candidate block group anew with the selected construction block as the new target block.

A pouring plan creation method according to the present invention is a pouring plan creation method in which a computer creates a pouring plan for pouring concrete. The pouring plan is a pouring order for each construction block, which sets the order in which concrete is poured into construction blocks into which the construction target is divided.
This computer performs a block group setting step of sequentially setting a candidate block group, which is a group of construction blocks to be successively driven, for the construction object, and a block group setting step of determining the driving order within the candidate block group. and performing an ordering step. By repeatedly performing the block group setting step and the intra-group order determining step, the driving order of the construction blocks constituting the construction target is determined.
The candidate block group is composed of a stacked block adjacent to the block of interest, which is the construction block serving as a reference for the candidate block group, and an expansion block located around the stacked block.
In the block group setting step, when the driving order in the previous candidate block group is determined, it is determined that among the already driven construction blocks, the driving to the adjacent construction block is not completed and the driving completion time is determined. selects the construction block that has already been driven in the earliest, and sets the candidate block group anew with the selected construction block as the new target block.

The expansion block is the construction block one level below the target block, and is preferably located outside the stacked block.

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

According to the present invention, it is possible to provide a pouring plan creation device and a pouring plan creation method that can create a suitable concrete pouring plan.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the drawings as appropriate. The figures are only shown schematically to provide a thorough understanding of the invention. Therefore, the present invention is not limited to the illustrated example. In each figure, common or similar components are designated by the same reference numerals, and their overlapping explanations will be omitted.

<Configuration of driving plan creation device according to embodiment>
With reference to FIG. 1, the configuration of a driving plan creation device 100 according to an embodiment will be described. FIG. 1 is a schematic configuration diagram of a driving plan creation device 100 according to an embodiment. The pouring plan creation device 100 is a device that creates a pouring plan for concrete pouring. The pouring plan creation device 100 can be used in various situations of pouring concrete, and the type, shape, and size of the object to be constructed, the method of pouring concrete, etc. are not particularly limited. The pouring plan indicates the order in which concrete is to be poured, and is, for example, associating information that identifies parts (for example, blocks) of the construction target with the order of pouring.

Referring to FIG. 2, a construction target for concrete work will be described. Figure 2 shows an example of the object to be concreted, where (a) is an image of the completed concrete structure A, and (b) is the concrete structure A shown in front. It shows the state as seen from. In this embodiment, as shown in FIG. 2(a), a concrete structure A that expands in the width, depth, and height directions is assumed as the construction target, and the pouring plan creation device 100 constructs the concrete structure A. Create a driving plan. In addition, concrete structure A is one that has an outstanding length in any one of the width, depth, and height directions (a long-shaped structure such as a column or beam), or one that has an outstanding length in any of the width, depth, and height directions. It may be a structure with outstanding length in two directions (a planar structure such as a wall or a floor).

Concrete structure A is divided into a plurality of areas, and the divided minimum unit area will be referred to as "construction block B". Construction block B is the minimum unit area for managing construction. Construction block B may be an area whose boundary with adjacent construction block B is physically determined by formwork, wire mesh, joint material, etc., or where the boundary with adjacent construction block B is physically determined. It may also be a virtual area that has not been created. Below, when showing and explaining a specific construction block B, it may be written as "construction block B (k, l, m)". "k,l,m" is identification information for identifying 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 arrangement order in the height direction. Note that the size of one construction block B (k, l, m) can be determined, for example, depending on the construction conditions for concrete pouring (in particular, the performance of the pump truck used for concrete pouring).

A placing plan creation device 100 shown in FIG. 1 creates a placing plan for a concrete structure A by simulation using a virtual three-dimensional space. In the simulation of the pouring plan, a pouring plan is created using a construction model C (see FIG. 1) which is an abstraction (modeling) of the concrete structure A. Like the concrete structure A, the construction model C is divided into construction blocks B (k, l, m).

As shown in FIG. 1, the implantation plan creation device 100 according to the embodiment includes a storage section 30 and a control section 40. The driving plan creation device 100 is, for example, a personal computer (PC) operated by a person in charge of creating a driving plan (hereinafter referred to as a "creator"), or a personal computer that is communicably connected to the personal computer. It is an application server. The creator here is, for example, a concrete worker.

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

The storage unit 30 stores information necessary for creating a driving plan (in this case, driving condition information 31 and a construction model C). The pouring condition information 31 includes information regarding the performance of the pump provided in the concrete pump truck, information regarding the pouring time interval, and the like. Furthermore, when pouring concrete using a plurality of concrete pump trucks, the pouring condition information 31 includes the number of pouring ports into which concrete is to be poured. The construction model C is an abstraction (modeling) of the construction target. The construction model C is divided into construction blocks B (k, l, m) like the construction target. In the construction model C, the positional relationship and size of each construction block B (k, l, m) are set.

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

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

The driving order creation unit 42 creates a driving plan using the construction model C. The driving order creating section 42 includes a block group setting section 43 and an intra-group order determining section 44 .
The block group setting unit 43 sequentially sets candidate block groups Q (see FIG. 4), which are a group of construction blocks B to be successively driven, for the construction model C (construction target).
The intra-group order determination unit 44 determines the driving order within the candidate block group Q set for the construction model C (construction target).

FIG. 4 shows an example of the candidate block group Q. FIG. 4 is a diagram for explaining the candidate block group Q, in which (a) is a perspective view of the candidate block group Q, and (b) is a plan view of the candidate block group Q. The candidate block group Q shown in FIG. 4 is defined by the geometric 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 serves as a reference for the candidate block group Q may be expressed as a "target block Ba." For example, at the time of setting the candidate block group Q, the block group setting unit 43 focuses on the driven construction block B in which at least one of the adjacent construction blocks Ba has not yet been driven and the driving completion time is the earliest. Select as block Ba.

Referring to FIG. 3, stacking of construction blocks B will be described. FIG. 3 is a diagram for explaining the stacking of construction blocks B. As shown in FIG. 3, in order to complete the stacking of the target block Ba, construction block Bb1 located in front of the target block Ba, construction block Ba2 located behind, construction block Ba3 located on the left, construction block Bb3 located on the right, It is necessary to drive all of the construction block Ba4 located there and the construction block Ba5 located directly above it. In addition, since pouring in the air is not possible, it is assumed that there is another construction block B (or a foundation, etc.) directly below the target block Ba, and the construction block B directly below the target block Ba is not considered here. I'll decide. In the following description, these construction blocks Bb1 to Bb5 may be referred to as "stacked blocks Bb" for the target block Ba. In other words, the block group setting unit 43 selects a construction block B for which the stacking has not been completed (the driving of any one of the stacked blocks Bb has not been completed) and whose driving completion time is the earliest. is selected as the block of interest Ba.

As shown in FIG. 4, the candidate block group Q in this embodiment is composed of an overlapping block Bb adjacent to the block of interest Ba, and an extended block Bc located around the lower layer of the overlapping block Bb. In this embodiment, the target block Ba itself and the construction blocks B directly below the target block Ba and the stacked blocks Bb1 to Bb4 are not included in the candidate block group Q. This is because it is assumed that these construction blocks B have already been driven due to the driving constraints described below. Note that the construction blocks B directly below the stacked 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. Note that the arrangement of the expansion blocks Bc shown in FIG. 5 is merely an example, and other arrangements are also possible. When describing the construction blocks Ba constituting the candidate block group Q, they may be referred to as "candidate blocks P" without distinguishing between the stacked blocks Bb and the expanded blocks Bc. That is, the candidate block group Q in this embodiment is composed of thirteen candidate blocks P.

If only the overlapping blocks Bb (5 blocks in FIG. 4) with respect to the block Ba of interest are set as candidate blocks P, the aim is to overlap the block Ba of interest in the shortest possible time. However, in such a method of setting candidate blocks P, when the driving order of all construction blocks B is determined, the maximum stacking time may not necessarily be shortened. Therefore, in this embodiment, as shown in FIG. 4, driving of the overlapping block Bb of the focused block Ba is completed early, that is, so that the driving constraint conditions of the overlapping block Bb are satisfied earlier. Candidate block P is expanded by adding construction block B (expansion block Bc) that is not directly related to the overlapping of Ba (total 13 blocks (5+8)). These eight additional expansion blocks Bc become noise when it comes to the shortest stacking time of the target block Ba, but are effective in shortening the maximum stacking time.

The intra-group order determination unit 44 determines the implantation order within the candidate block group Q. The method of determining the order by the intra-group order determining unit 44 is not particularly limited, and various methods can be used. The intra-group order determining unit 44 may determine the driving order of the construction blocks B according to a predetermined rule, or may determine the driving order of the construction blocks B at random. Furthermore, the intra-group order determining unit 44 has a function of determining whether or not the driving of the construction block B conforms to preset constraint conditions. The constraints on implantation may be arbitrary, and their contents are not limited. The intra-group order determining unit 44 determines, for example, whether or not it is possible to drive the construction block B.

The driving order creation unit 42 searches for a driving order until driving of all construction blocks B is completed, for example, as follows.
(1) Select the target block Ba based on the driving completion time.
(2) Select one location from among the candidate blocks P for which implantation has not been completed, and determine whether or not the implantation constraints are met. If it is possible to drive, the selected construction block B is considered to have been driven.
(3) Repeat the operation in step (2) in sequence until all candidate blocks P in the candidate block group Q are completed.
(4) When the implantation of all candidate blocks P is completed, search for the next target block Ba and perform the processes of steps (2) and (3). In other words, the process does not proceed to the next target block Ba until the candidate block group Q has been implanted.
Here, in this embodiment, as a driving constraint condition, it is assumed that driving cannot be performed in a shape that protrudes in two steps in the height direction. For example, in order to drive the stacked block Bb5 directly above the block of interest Ba in FIG. 3, the block of interest Ba in FIG. 3 and the stacked blocks Bb1 to Bb4 on its front, rear, left and right sides must have been driven.

The order evaluation unit 45 shown in FIG. 1 evaluates the input order created by the input order creation unit 42. The method for evaluating the implantation order is not particularly limited, and various methods can be used. The order evaluation unit 45 evaluates the placement order based on, for example, the stacking time. In this embodiment, a mutually coupled neural network calculation method is applied to express the evaluation of the overlapping time concisely.

We will explain the evaluation of overlapping time using a mutually coupled neural network calculation method. First, the expected driving range is divided into several construction blocks (in the following explanation, they may be simply referred to as "blocks"). As long as there are no geometrical restrictions, the driving blocks may be driven in any order starting from any point. If construction blocks are represented by "○ (white circles)" and routes are represented by lines, for example, in an example where there are three construction blocks, an interconnected neural network consisting of three units as shown in Figure 5 will be used. becomes. FIG. 5 is an image diagram of a mutually coupled neural network. Route candidates are possible between all construction blocks that are a combination of two, and can be oriented in both directions. However, each construction block passes through only once, and it is driven into only one construction block at a time (if there is only one driving hole).

As shown in FIG. 6, when a mutually coupled neural network is expressed as a matrix-like hierarchical network of blocks and orders, it becomes a Hopfield neural network. FIG. 6 is an image diagram of a Hopfield neural network. In this matrix-like network, the construction blocks are also interconnected, and the flow of information can be considered to be the same as the original interconnected neural network. “○ (white circle)” in FIG. 6 represents an information processing section called a unit. Unit is a term used in neural networks, and is generally used as the name of a function that receives the output of another unit and returns (outputs) a certain value (for example, "-1 to +1"). In each driving order, there are the same number of units (3 blocks) corresponding to the construction blocks. Since all construction blocks are driven, there will be 3 units, the same number both vertically and horizontally (imax=jmax). In the figure, each implant sequence is called a layer. In this network, units in adjacent layers are connected, but units in the same layer or units in non-consecutive layers are not connected. In this embodiment, a case will be described in which the overlapping time is expressed using such a matrix.

The formulation will be explained below. As shown in FIG. 7, a matrix is created as described above, with the block number "i" listed vertically and the implantation order "j" listed horizontally. This matrix is a hierarchical network in which every layer has the same number of units (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. It is.

The output of the unit is ``1 (x <sub>ij</sub> = 1)'' when a block with the corresponding block number is written, and ``0 (x _ij = 0)'' when it is not written. The weight between units is determined by the time required to insert the block corresponding to output unit "i(j-1)" (w _{i(j-1)→i(j)} = w _{i( j-1)} ) .
The sum of the outputs of each unit in the previous layer multiplied by the weight of the path between each unit and the unit of interest is calculated sequentially from the start of implantation. The driving start time and driving completion time of each construction block are expressed by equations (1) and (2) according to the depth of the layer to be summed.

The overlapping time interval is evaluated using equation (3) as the difference between the driving completion time of the block of interest and the driving completion time of the overlapping block. Here, as shown in FIG. 8, from the geometric connectivity of the blocks, we use the formula ( 4) was introduced. The maximum number of overlapping blocks for one block of interest is 5 blocks. Here, the target block is a partner construction block that is paired with the block of interest and for which the overlap time is to be calculated.

<About the method for creating a driving plan according to the embodiment of the present invention>
A method for 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 for creating a driving plan according to the embodiment. The pouring plan is, for example, a pouring order for each construction block B, which sets the order in which concrete is poured into the construction blocks B into which the construction target is divided.

First, the creator sets construction conditions, a construction model C that is an abstraction of the concrete structure A, etc. in the pouring plan creation device 100 via the condition setting unit 41 (step S101). Note that the condition setting unit 41 may calculate these pieces of information without relying on the creator's input operation or from other information input by the creator.

For example, the creator places a virtual block D (k, l, m), which is an abstraction of the construction block B (k, l, m), in a three-dimensional virtual space. Specifically, the position of the construction block B (k, l, m) is set as the coordinate value (X, Y, Z) of the orthogonal coordinate system set in the three-dimensional virtual space, and the virtual block D (k, l, m ). Here, "X" corresponds to, for example, the horizontal position of construction block B (k, l, m), and "Y" corresponds to, for example, the depth direction of construction block B (k, l, m). "Z" corresponds to the position of the construction block B (k, l, m) in the height direction, for example. Thereby, the relative positional relationship of the construction block B (k, l, m) is reproduced on the three-dimensional virtual space using the coordinate values set for the virtual block D (k, l, m). In the following explanation, construction block B refers to abstracted virtual block D.

In addition, the creator can set, 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, for example, from the size of the construction block B (k, l, m) and pump performance.
The creator also sets, for example, the number of pouring holes into which concrete is poured (corresponding to the number of pump trucks in the case of pouring concrete using pump trucks).
Further, the creator sets, for example, the first construction block B (starting block) at which driving starts. For example, the creator arbitrarily sets one of the construction blocks B that are in contact with the ground (that is, the construction blocks B that are not driven into the air) as the start block. Note that if there is a plurality of slots, a start block is set according to the number of slots.

Next, the creator instructs the driving plan creation device 100 to start calculating the driving order. Thereby, the implantation plan creation device 100 executes the processing from step S102 onwards. Note that the driving plan creation device 100 may start calculating 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 pouring order creation unit 42 sets information indicating that concrete is poured first in the first construction block B (starting block), and places the start block. finish it. This completes the driving of the construction block B (starting block).

Next, the block group setting unit 43 searches for the target block Ba (see FIG. 4) (step S103). The block Ba of interest is the construction block B for which overlapping has not been completed and the driving completion time is the earliest among the construction blocks B for which driving has been completed (driving blocks). The term "overlapping is incomplete" means that the driving of at least one of the construction blocks B adjacent to the construction block B that has been completed is not completed. In other words, when the driving of all the construction blocks B adjacent to the construction block B is completed, the stacking of the construction blocks B is completed. The block group setting unit 43 selects the construction block B that meets the above-mentioned conditions as the block of interest Ba.

When there is a target block Ba that can be selected and one construction block B is selected as the target block Ba (“Yes” in step S104), the intra-group order determining unit 44 repeatedly performs the processes from step S105 to step S110, and selects candidates. The driving order of the construction blocks B (that is, the candidate blocks P (see FIG. 4)) included in the block group Q (see FIG. 4) is determined. Note that the process of determining the driving order of candidate blocks P shown in FIG. 9 is just an example, and the process of determining the driving order of candidate blocks P is not limited to what is described here.

The intra-group order determining unit 44 searches for a candidate block P (see FIG. 4) to be inserted next (step S105). The intra-group order determining unit 44 selects one location from among the candidate blocks P that have not been implanted. The method for selecting candidate blocks P is not particularly limited. If there is a selectable candidate block P (“Yes” in step S106), the intra-group order determining unit 44 determines whether the selected candidate block P satisfies the implanting constraint conditions (step S107).

If the driving constraint conditions are not met (“No” in step S107), the intra-group order determining unit 44 searches for other candidate blocks P (step S109), and newly selects the other searched candidate block P. (Step S105). On the other hand, if the pouring constraint conditions are met (“Yes” in step S107), the intra-group order determining unit 44 marks the selected candidate block P as having been poured by setting information indicating the order in which concrete is poured. (Step S108). After that, the intra-group order determining unit 44 searches for the next candidate block P (step S110), and newly selects the searched next candidate block P (step S105).

If there is no candidate block P that can be selected in the candidate block group Q (including when there is no candidate block P) (“No” in step S106), the block group setting unit 43 selects the next block of interest Ba and creates a new block of interest. The process moves to Ba (step S111). Specifically, the block group setting unit 43 searches for a new target block Ba (see FIG. 4) (step S103). Then, the intra-group order determining unit 44 repeatedly performs the processing from step S105 to step S110, and determines the implantation order of the candidate blocks P included in the candidate block group Q (see FIG. 4) based on the newly selected target block Ba. do.

If there is no target block Ba that can be selected (including when there is no target block Ba) (“No” in step S104), the driving order of all the construction blocks B has been determined, so the order evaluation unit 45 selects the created driving order. The maximum overlapping time in is calculated (step S112). The creator determines whether to create the dosing order again based on the calculated maximum dosing time. For example, if the maximum stacking time is within the allowable range, the creator performs construction in the created order, and if it is not within the allowable range, the creator changes the construction conditions, etc. Recreate the typing order. The allowable range of 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 listed in the "Standard Specifications for Concrete" published by the Japan Society of Civil Engineers. be.

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

With reference to FIGS. 10 and 11, the effects of the driving plan creation device 100 according to the embodiment will be supplemented. The inventor proposes two cases in which the candidate block P is not extended (the candidate block group Q is composed of only the overlapping blocks Bb) and the case where the candidate block P is extended (the candidate block group Q is composed of the overlapping blocks Bb and the extended blocks Bc). We performed simulations for each case (consisting of two types) and compared the results. In the simulation, it was assumed that a structure composed of wall slabs (see FIG. 10) was implanted in three layers.

FIG. 10 is a schematic diagram of the structure used in the simulation. FIG. 10(a) shows the first layer structure, FIG. 10(b) shows the second layer structure, and FIG. 10(c) shows the structure of the second layer. ) indicates the third layer structure. The squares in FIG. 10 are each construction block B, and the numbers inside the squares indicate block numbers. Since implantation cannot be performed in the air, the 21 blocks of the first layer shown in FIG. 10(a) are candidates for the starting block in the simulation. There are four regions in the first and second layers where implantation is not performed.

The simulation results will be explained with reference to FIG. 11. FIG. 11 is a diagram for explaining the simulation results. FIG. 11(a) shows the simulation result when the candidate block P is not expanded, and FIG. 11(b) shows the simulation result when the candidate block P is expanded. Simulation results are shown.

11(a) and 11(b) both correspond to the structure of the first layer, and the numbers inside the rectangles indicate the maximum overlapping time when driving starts from the construction block B concerned. For example, in the case where candidate block P in FIG. 11(a) is not expanded, the maximum stacking time is "120 minutes" when starting from construction block B with block number "1", and the maximum stacking time is "120 minutes"; When starting pouring from construction block B, the maximum overlapping time is "130 minutes." Here, in the case where the candidate block P shown in FIG. 11(a) is not expanded, the average maximum overlapping time when starting driving from each construction block B was "153.3 minutes". On the other hand, when the candidate blocks P shown in FIG. 11(b) are expanded, the average maximum overlapping time when starting driving from each construction block B was "148.1 minutes".

As a result of comparing and verifying Figs. 11(a) and (b), we found that if the candidate block P shown in Fig. 11(b) is expanded, the maximum stacking time will not necessarily be shortened, but The average value of the maximum overlapping time when starting the process is kept short. Furthermore, when the candidate block P shown in FIG. 11(b) is expanded, there is a tendency for the maximum overlapping time to decrease when starting from near the center (in other words, there is a tendency to suppress the peak of the maximum overlapping time). be). For example, when starting pouring from construction block B with block number "11", the maximum pouring time is "220 minutes" when candidate block P shown in FIG. 11(a) is not expanded. , the maximum overlapping time when expanding the candidate block P shown in FIG. 11(b) was "200 minutes".

Although the embodiments of the present invention have been described above, the present invention is not limited thereto, and can be implemented without changing the spirit of the claims.
