Description

  The present disclosure relates to a construction management method for pile hole excavation.

Whether or not the excavation of the pile hole has reached the support layer is determined based on the current value of the electric motor of the excavator together with the driving sound and rotational torque of the excavator (see, for example, Patent Document 1).
Specifically, at the excavation site of a pile hole, in order to confirm whether the pile hole has reached the support layer, the current value of the electric motor of the excavator is measured, and a construction management device (computer) or pen A chart of measurement results is created using the recorder. The person in charge of the excavation work of the pile hole can confirm whether or not the pile hole being excavated has reached the support layer by looking at the chart.

Japanese Patent No. 4958028

  Generally, charts are collected for all pile holes and sent to a pile foundation construction manager after a while after construction of the pile foundation, for example, several weeks later. For this reason, the pile foundation construction manager can obtain the chart, but cannot obtain it quickly. Therefore, the construction manager who should supervise the person in charge of the excavation work cannot immediately check the chart unless he / she is at the construction site for the excavation of the pile hole. As a result, there is a problem that countermeasures cannot be immediately implemented even if a problem occurs in excavation work.

  In view of the above circumstances, the purpose of at least one embodiment of the present invention is to enable a construction manager of a pile foundation to reliably and quickly grasp whether a pile hole has reached a support layer, It is to provide a construction management method for excavation of pile holes.

An image sending step of sending the image of the chart obtained in the photographing step to the construction manager of the pile foundation on the day when the excavation of the pile hole is completed.

According to the said structure (1), the image of a chart is sent to the construction manager of a pile foundation on the day which excavated the pile hole. For this reason, the construction manager of the pile foundation can surely and quickly grasp whether or not the pile hole has reached the support layer.
Further, when the construction manager looks at the image on the chart and determines that there is a possibility that the support layer has not been reached, the countermeasure can be immediately examined. In particular, various countermeasures can be considered during the day of excavation of the pile hole. And it will be possible to build a pile hole as designed by implementing countermeasures promptly. Therefore, construction quality can be ensured by being able to quickly grasp the construction results.
In addition, since the image information on the chart includes date information of the photographed image, the construction manager can easily confirm whether or not the sent image is an image on the day when the pile hole is excavated. Furthermore, since time information is also included, it can be easily confirmed whether or not it is mixed with information on other pile holes excavated on the same day.

  Hereinafter, some embodiments of the present invention will be described with reference to the accompanying drawings. However, the dimensions, materials, shapes, relative arrangements, etc. of the components described in the embodiments or shown in the drawings are not intended to limit the scope of the present invention, but are merely illustrative examples. Absent.

FIG. 1 is a flowchart showing a schematic procedure of a construction management method for pile hole excavation according to an embodiment of the present invention. 2 and 3 are diagrams for explaining the steps in FIG.
As shown in FIG. 1, the construction management method for pile hole excavation includes an index measurement step S1, a chart creation step S2, a photographing step S3, and an image sending step S4.

In the index measurement step S <b> 1, as shown in FIG. 2, an index corresponding to the resistance from the ground acting on the excavator 2 is measured while excavating the pile hole 4 with the excavator 2. The index changes depending on the resistance of the ground, and the resistance of the ground can be obtained based on the index.
In the chart creation step S2, as shown in FIG. 3, the chart 6 is created based on the index measured in the index measurement step S1. For example, one axis (vertical axis) of the chart 6 is the depth or excavation time of the pile hole 4, and the other axis (horizontal axis) of the chart 6 is the size of the index.

In the photographing step S3, as shown in FIG. 3, the image 6 of the chart 6 is acquired by photographing the chart 6 created in the chart creating step S2 using the photographing device 8.
The image 9 includes captured date information and time information. The date information and time information may be displayed on the image 9.
As the imaging device 8, for example, a still camera, a video camera, a mobile phone, a smartphone, or a tablet PC (personal computer) can be used.
The image 9 of the chart 6 is not limited to a still image and may be a moving image. Further, the image of the chart 6 may be a still image obtained by extracting a part of the moving image.
In the case of a still image, the person in charge of excavating the pile hole 4 captures the chart 6 immediately after determining that the pile hole 4 has reached the desired support layer. When it is determined that the pile hole 4 has reached the desired support layer, the chart 6 is photographed immediately, so that the shape of the chart 6 can be prevented from being processed. The same effect can be obtained in the case of a moving image.
The operation of the imaging device 8 is performed by, for example, a person in charge of excavating the pile hole 4, but may be performed by another person.

In the image sending step S4, as shown in FIG. 3, the image 9 of the chart 6 is sent to the construction manager of the pile hole 4 on the day when the excavation of the pile hole 4 is completed. Specifically, the image sending step S4 includes a date determining step S41 and a sending step S42 as shown in FIG.
In order to transmit the image 9 of the chart 6, for example, when a transmission button is pressed, a date determination step S41 is performed. In the date determination step S41, it is determined whether or not the date information included in the image 9 of the chart 6 matches the date information of the current day to be sent.
For example, the determination is performed by an application provided in the photographing apparatus 8 such as a mobile phone, a smartphone, or a tablet PC.
The transmission step S42 transmits the image 9 of the chart 6 subsequently when it is determined that they match in the date determination step S41.
The image 9 of the chart 6 is transmitted to the information terminal 11 used by the construction manager of the pile hole 4 via a communication network such as the Internet 10. As the information terminal 11, for example, a mobile phone, a smartphone, a tablet PC, or a desktop PC can be used.
On the other hand, if it is determined that the dates do not match, an error message is displayed and the image 9 is not transmitted.
The construction manager of the pile hole 4 is a prime contractor who orders excavation from the subcontractor when the person in charge of the excavation work of the pile hole 4 is generally a subcontractor.

In order to transmit the image 9 to the information terminal 11, the photographing device 8 preferably has a communication function. However, a communication device for transmitting the image 9 is prepared separately from the photographing device 8. Also good.
Moreover, although the operation for transmitting the image 9 is performed by the person in charge of excavation of the pile hole 4, for example, it may be performed by another person.

  The imaging device 8 includes alarm means (not shown) that periodically displays or sounds that the image 9 has not been transmitted at a preset time interval when the image 9 has not been transmitted during the day of shooting. .

According to the above configuration, the image 9 of the index chart 6 is sent to the construction manager of the pile hole 4 on the day when the excavation of the pile hole 4 is completed. For this reason, the construction manager of the pile hole 4 has passed through the non-support layer (soft layer) 12 shown in FIG. 2 and has reached the support layer 14 stronger than the non-support layer 12. Can be surely and quickly grasped.
In addition, when the construction manager looks at the image 9 of the chart 6 and determines that there is a possibility that the support layer 14 has not been reached, a countermeasure can be immediately examined. In particular, various countermeasures can be considered during the day when the pile hole 4 is excavated. And it will be possible to build a pile hole as designed by implementing countermeasures promptly. Therefore, construction quality can be ensured by being able to quickly grasp the construction results.
Since the image 9 of the chart 6 includes the date information taken, the construction manager easily confirms whether or not the sent image 9 is the image 9 during the day when the pile hole 4 was excavated. be able to. Furthermore, since only the image 9 determined to match in the date determination step S41 is transmitted, it is possible to reliably prevent an error such as transmitting an image of another pile hole excavated on another day.
Moreover, since the time information is also contained in the image 9, it can be easily confirmed whether it is not mixed with the information of other pile holes excavated on the same day.

In some embodiments, the index corresponding to the resistance is the current value of the electric motor of the excavator 2.
According to the above configuration, since the current value of the electric motor of the excavator 2 is measured as an index, the index can be easily measured.
In this case, for example, as shown in FIG. 2, an ammeter 15 is attached to the excavator 2.
Note that when the excavator 2 has a hydraulic motor as an actuator, the hydraulic pressure may be measured as an index corresponding to the resistance.

In some embodiments, in the chart creation step S2, as shown in FIG. 3, the chart 6 is formed on the monitor 18 using the computer 16, and the chart paper is used using the pen recorder. One or both of the formations of the chart 6 are performed.
According to the above configuration, since one or both of the chart 6 formed on the monitor 18 and the chart 6 formed on the chart paper are photographed, the image 9 of the chart 6 can be easily acquired.
In this case, a measuring instrument for measuring an index such as the ammeter 15 is connected to the computer 16 and the pen recorder so as to communicate with each other. The computer 16 and the pen recorder can create the chart 6 based on the index sent from the measuring instrument. Note that the term “communicatable connection” means connection by wire or wireless.

In the chart 6 to be created, when one axis is the depth, the depth of the pile hole 4 is measured by the depth meter 19 (see FIG. 2). The depth meter 19 is communicably connected to the computer 16, and the computer 16 can create the chart 6 based on the depth of the pile hole 4 sent from the depth meter 19.
Alternatively, when one axis of the chart 6 is time, the person in charge of excavating the pile hole 4 may write the depth of the pile hole 4 measured by the depth gauge 19 on the chart 6.
In Chart 6, an integrated current value obtained by integrating the current value every predetermined time, for example, every 0.1 m may be adopted for the other axis.

FIG. 5 is a flowchart showing a schematic procedure of a pile hole construction management method according to another embodiment of the present invention.
The pile hole construction management method shown in FIG. 5 further includes a recording step S5 and a chart determination step S6 when compared with the pile hole construction management method shown in FIG.
The recording step S5 is performed in parallel with the chart creating step S2. In the recording step S5, the index measured by the index measuring step S1 is stored in the recording device 20. For example, at this time, the index is stored in the recording device 20 together with the measurement time of the index and, if necessary, a symbol representing the excavation site of the pile hole and a symbol representing the number of pile holes 4. The index is stored in the recording device 20 as digital data. The index stored in the recording device 20 can be read but not rewritten.
For example, the recording device 20 is installed in the excavator 2 together with a measuring device for an index such as an ammeter 15 so as to be able to communicate with the measuring device.

In the chart determination step S6, the index stored in the recording device 20 is compared with the image 9 of the chart 6 obtained in the photographing step S3, and the index stored in the recording device 20 and the chart obtained in the photographing step S3 are compared. It is determined whether the six images 9 match. This determination is performed by a person in charge of excavation work, for example.
In the pile hole construction management method shown in FIG. 5, in the image sending step S <b> 4, the determination result of the chart determination step S <b> 6 is sent to the construction manager of the pile hole 4 together with the image 9 of the chart 6.
According to the above configuration, since the determination result is sent together with the image 9 of the chart 6, the construction manager of the pile hole 4 determines whether or not the chart 6 in the sent image 9 is authentic. After confirming, it can be easily grasped whether the pile hole 4 has reached the support layer 14 or not.

In the chart determination step S6, the index stored in the recording device 20 is used to determine whether the index stored in the recording device 20 matches the image 9 of the chart 6 obtained in the photographing step S3. A comparison chart may be created based on the above.
Alternatively, in the chart determination step S6, the index value is read from the chart 6, the read value is compared with the index value stored in the recording device 20, and it is determined whether or not they match. Also good.

FIG. 6 is a flowchart showing a schematic procedure of a pile hole construction management method according to another embodiment of the present invention. FIG. 7 is a diagram for explaining the process in FIG.
The pile hole construction management method shown in FIG. 6 further includes a transmission step S7 and an index storage step S8 when compared with the pile hole construction management method shown in FIG.

In the transmission step S7, as shown in FIG. 7, the index stored in the recording device 20 is transmitted toward the server 22 installed at a place different from the excavation site of the pile hole 4. The server 22 is installed, for example, in a company building to which a person in charge of excavation work belongs. For example, the index is transmitted to the server 22 via the Internet 10. In order to transmit the index to the server 22, a recording device having a communication function may be used as the recording device 20, or a communication device may be connected to the recording device 20. The transmission step S7 is preferably automatically performed periodically at predetermined time intervals.
In the index storage step S8, the index sent in the transmission step S7 is stored in the server 22. The index stored in the server 22 can be read but not rewritten. The index storing step S8 is also preferably performed automatically.

  According to the said structure, it can be confirmed based on the parameter | index stored in the server 22 whether the pile hole 4 reached | attained the support layer 14 at any time as needed.

  Finally, the present invention is not limited to the above-described embodiments, and includes forms obtained by modifying the above-described embodiments and forms obtained by appropriately combining these forms.
