Description

The present invention relates to a method of performing process control of ground improvement work using artificial intelligence (AI), a system for carrying out the method, and a jig used for them.

In the ground improvement work called the surface layer mixing treatment method, the cement-based solidifying material is sprayed on the soft ground, and by stirring, mixing, and rolling, and in the ground improvement work called the deep layer mixing treatment method, the cement-based solidifying material and water. The ground improvement was carried out by pumping the solidifying material slurry containing the above-mentioned material into the ground and stirring and mixing it with the soil in the ground.

In this ground improvement work, after performing a ground improvement step of mixing and stirring the cement-based solidifying material to the ground to be improved, or a ground improving step of pumping the solidifying material slurry and stirring and mixing with the soil, normal ground improvement is performed. In order to carry out a quality inspection of whether or not the work was carried out, the test cores of the ground to be improved were collected by boring, and the quality test of the collected test cores was performed to judge the quality of the ground improvement work. ..

Perform the quality test according to the following procedure. After the ground improvement process is completed, boring is performed 2-3 days later, test cores are collected, and the collected test cores are sent to the quality test test site. Then, first, 7 days after collection, a preliminary test of the uniaxial compression test of the test core is performed. As a result of the preliminary test, if the test result at the age of 7 days is equal to or higher than the design standard strength, the test core is stored until 28 days have passed after collection, and 28 days later, the uniaxial compression test is performed. Perform this test. Then, if the test core shows good strength as a result of this test, it is finally judged that the ground improvement work has been carried out well.

Here, when performing a preliminary test or performing a main test, the test core is a core (defective core) that is not suitable for a quality test, for example, a core containing cracks that do not exceed the length of the test piece. , The core is a mixture of soil lumps, the core is not shaped, etc., and the uniaxial compression test cannot be performed. Then, when the test core is found to be such a defective core, it becomes necessary to re-collect the test core by boring the ground where the ground improvement work has been performed again.

Then, the period from the first collection of the test core to the re-collection, that is, 7 days if the preliminary test shows that the core is defective, and the case where the core is found to be defective in the main test. For 28 days, construction work, etc. following the ground improvement work will not be possible, leading to a delay in the construction period.

Therefore, before sending the test core to the quality test test site, it is necessary to determine whether the core is suitable for the test or a defective core. Currently, after collecting the test core by boring, the site manager or designer confirms the state of the test core visually or by core sketch, etc., and the core is suitable for the test or a defective core. Is determined. Then, when the collected test core is determined to be a core suitable for the test, the test core is sent to the test site of the quality test, and when it is determined to be a defective core, the test core is sent again. Boring is performed and the test core is collected.

However, until now, since the site manager and the designer have visually determined whether the core is suitable for the test or the defective core, there are many variations depending on the discriminator, and the core is suitable for the test. Since it is difficult to accurately determine whether the core is a defective core or a defective core, there is a problem that an erroneous determination may be made. In addition, for this reason, the discriminator needs a great deal of experience, but there is also a problem that there is a shortage of discriminators who can accurately discriminate because it takes time to train skilled discriminators. rice field.

To have
It is a process management method of ground improvement work using artificial intelligence (AI). Hereinafter, artificial intelligence (AI) will be abbreviated as AI.

The process management method of the ground improvement work of the present invention has a learning process. In the learning step, the AI is made to learn the image data groups of the normal core and the defective core stored in the storage unit of the server as learning data, thereby generating a data group indicating the defective core, and the generated defective core. This is a step of storing the data group indicating the above in the storage unit.

In the learning process, the image data group to be learned by AI is collected within 168 hours after the completion of the ground improvement work by boring the target ground after the ground improvement process is performed in order to perform the quality test in the past. This is an image of the test core taken at least 72 hours after the completion of the ground improvement work, and the preliminary test of the quality test 7 days after collection or the main test of the quality test 28 days after collection. Occasionally, the image data group of the test core stored in the storage part of the server is classified into a normal core determined to be a core suitable for the quality test and a defective core determined to be a core not suitable for the quality test. Is.

In the learning process, the number of image data to be learned by AI is not particularly limited, but the larger the number, the higher the accuracy. Further, in the learning step, each time the image data of the test core newly captured and classified as a normal core or a bad core is added to the image data to be learned by AI, the image stored in the storage unit is stored. The data may be used to retrain the AI.

Then, in the learning process, the image data groups of the normal core and the defective core stored in the storage unit of the server are learned as learning data to generate a data group indicating the defective core, and the generated defective core is generated. The indicated data group is stored in the storage unit. The data group indicating the defective core generated by AI in the learning process is the data to be compared with the test core to be determined in the analysis process.

The process management method of the ground improvement work of the present invention includes an imaging process. In the imaging process, the test core to be judged collected within 168 hours after the completion of the ground improvement work is imaged from the ground where the ground improvement work has been performed, at least 72 hours after the completion of the ground improvement work. It is a process to do.

In the ground improvement work, the cement-based solidifying material is sprayed on the soft ground to be improved, stirred and mixed, or the solidifying material slurry is pumped into the ground to be improved. The ground improvement process is carried out by stirring and mixing with soil inside. After the ground improvement process is completed, a test core is collected by boring to determine whether the ground improvement has been performed normally. Then, after collecting the test core to be determined, the collected test core is wrapped in a curing sheet or the like.

The time for collecting the test core to be determined is appropriately selected within 168 hours after the completion of the ground improvement work. Then, it is preferable to collect the test core from the ground to be improved within 72 hours to 96 hours after the completion of the ground improvement work, because the test core is less likely to be damaged when the test core is collected. .. In addition, when collecting the test core, if the test core can be collected from the ground to be improved without damaging it, the test is performed immediately after the completion of the ground improvement work or within 72 hours after the completion of the ground improvement work. The core can be collected. In addition, if the result of the test core collected for the quality test after the ground improvement work is a defective core, the test core should be collected again from the target ground of the ground improvement work. However, in that case, the test core to be judged again is collected within 168 hours after the completion of the ground improvement work.

Then, in the imaging step, immediately before photographing the test core to be determined, the curing sheet wrapping the test core is peeled off for the purpose of preventing drying and the like, and an image of the test core to be determined is imaged.

In the imaging process, the imaging time of the test core is at least 72 hours after the completion of the ground improvement work, and is appropriately selected from 72 hours to 168 hours after the completion of the ground improvement work. .. As an imaging step, for example, (1) when the test core is collected between 72 hours and 96 hours after the completion of the ground improvement work, immediately after the collection, for example, within 48 hours after the collection of the test core. Imaging of the test core can be mentioned. Further, for example, (2) when the test core is collected within 72 hours after the completion of the ground improvement work, the test core may be imaged 72 hours or more after the completion of the ground improvement work. .. Further, for example, (3) the test core is collected between 72 hours and 96 hours after the completion of the ground improvement work, and the test core is collected immediately after the collection, for example, within 48 hours after the test core is collected. If it is determined that the core is defective as a result of performing an imaging process, performing an imaging process, and further performing a transmission process, an analysis process, and a confirmation process, the test core is collected again from the target ground and the test core is imaged. To do. Further, for example, (4) the test core is collected within 72 hours after the completion of the ground improvement work, and after 72 hours or more have passed after the completion of the ground improvement work, the test core is imaged to perform the imaging process. Further, when it is determined that the core is defective as a result of performing the transmission step, the analysis step, and the confirmation step, the test core may be collected again from the target ground and the test core may be imaged.

In the imaging process, the imaging device for capturing the test core is not particularly limited as long as it is a device capable of obtaining the captured image as digital data, and examples thereof include a digital camera and a smartphone having an imaging function. Then, by imaging the test core with an imaging device, image data of the test core to be determined is obtained.

The process control method of the ground improvement process of the present invention includes a transmission process. The transmission step is a step of transmitting the image data of the test core to be determined obtained by performing the imaging step to the server.

In the transmission process, the method of transmitting the image data of the test core to be judged to the server is not particularly limited, and is transmitted from a computer such as a desktop personal computer or a mobile personal computer connected to the server via the Internet, or a smartphone. , A method of directly transmitting the image data stored in the device to the storage unit of the server, or by uploading the image data to the upload database using the uploading software, the image data is stored in the storage unit of the server. There is a method of sending.

The quality control method for ground improvement work of the present invention includes an analysis step. In the analysis process, the image data of the test core to be determined received by the receiving unit of the server is compared with the data group indicating the defective core stored in the storage unit by AI, and the test core to be determined is determined. , It is a step of determining whether or not it corresponds to a defective core.

In the analysis step, AI recognizes the degree of agreement with the data group indicating the defective core in the test core to be determined, and determines whether or not it corresponds to the defective core based on the degree of agreement.

The process management method of the ground improvement work of the present invention has a confirmation process. The confirmation step is a step of confirming the analysis result in the analysis step. In the confirmation process, the analysis result in the analysis process is received from the transmission part of the server via the Internet via a computer such as a mobile personal computer or a smartphone, or uploaded to the upload database by the server. By receiving the analysis result on a computer such as a mobile personal computer or a smartphone for receiving the analysis result using the software for acquiring the uploaded analysis result, the acquirer of the analysis result confirms the analysis result. do.

Then, the confirmation step is performed, and if the analysis result is that the test core is a normal core, the imaged test core is sent to the quality test test site. On the other hand, if the analysis result shows that the test core is a defective core, the ground where the ground improvement work has been performed is bored again to obtain a new test core. For this reason, in the process control method for the ground improvement work of the present invention, if the confirmation result is a defective core, recollection by boring can be performed at that time, so that the ground improvement work is completed. After that, when the sampling of the test core is inappropriate compared to the conventional quality control method in which it is found that the test core needs to be recollected in the preliminary test 7 days later or the main test 28 days later. Less time loss. Further, in the process management method of the ground improvement work of the present invention, it is possible to promptly confirm whether the test core is a normal core or a defective core after performing the imaging process, so that the confirmation result is a defective core. In that case, since the recollection by boring can be performed at that time, the test core for the preliminary test after 7 days can be recollected within 7 days after the completion of the ground improvement work.

In the process control method of the ground improvement work of the present invention, it can be determined whether or not the test core collected by boring is a core suitable for the quality test without depending on the experience of the discriminator. That is, in the process control method of the ground improvement work of the present invention, there is less variation than when the judgment is made by a person, and the erroneous judgment by the judgment person can be reduced. Compared to the quality control method, there is less time loss when the test core is improperly collected.

In the process control method of the ground improvement work of the present invention, since AI determines whether or not the test core collected by boring is a core suitable for the quality test, it is not necessary to train a skilled judge.

The server used in the quality control method of the ground improvement work of the present invention and the AI and the storage unit provided in the server are not particularly limited.
