Description

Prospecting survey obstacle analysis system

[0001] The present invention relates to an obstacle analysis system for exploration drilling.

[0002] A trial excavation survey is a construction work carried out before construction begins to check whether there are any factors at the excavation site that could affect the construction of a structure. In order to investigate the geology or buried objects underground, a portion of the ground is excavated prior to construction work to confirm the location and depth of underground buried objects (rocks, foundations, piles, cavities, waste, gas pipes, water pipes, etc.). Trial excavations are necessary because without trial excavation work, there is a risk of accidentally cutting important underground infrastructure facilities, which could lead to a major accident, or because a cavity that has appeared underground could be unnoticed and heavy objects such as heavy machinery could be placed on the surface, causing subsidence.

[0003] Trial excavation work involves surveying the site using construction machinery such as excavators and backhoes to check for buried obstacles (such as waste illegally dumped by previous owners or construction companies, foundations of previous buildings, structures including piles, and natural objects such as rocks and stones) and cavities. Trial excavation work is a time-consuming process that requires the maintenance of expensive construction machinery and waste disposal, so there are currently few companies willing to undertake the work.

[0004] When excavation contractors discover structures from previous buildings or illegally dumped waste during pile or foundation work, they conduct excavation surveys in advance to prevent unexpected removal and disposal costs and construction work from being extended.One example of excavation work involves using an excavator such as a pole erection vehicle to conduct an investigation at five locations (the center and four diagonal corners) for one pile of a planned building, to check that there are no obstacles to the pile work, measure the depth of the excavation, record the location of any underground obstacles, and submit a excavation survey report to the client.

[0005] During a test excavation survey, if an obstacle is encountered during drilling using the auger (a screw-shaped drilling device at the tip) of a borehole excavator such as a pole-setting vehicle, the auger must be removed and the obstacle's shape, depth, and type must be investigated from the ground surface using ultrasonic, high-frequency, or other measuring devices. While it is desirable to be able to determine the type and size of the obstacle from the measuring device data, no rational method for this has been developed. When abandoned items are discovered on the site, if the contract with the seller waives responsibility for removing underground obstacles, the construction client must remove them at their own expense. This is usually not included in the construction estimate, resulting in unexpected costs and significant impacts on the original construction schedule. Furthermore, if the piles interfere with underground obstacles during construction, they must be offset. This requires structural calculations to achieve this offset, which increases the size of the foundation and, depending on the extent of the offset, may require application for a plan change. Construction work will be suspended until permission to change the plan is granted, and the pile driver will remain on site, which will result in double or triple the costs of removing obstacles, industrial waste disposal, increasing the foundation, design fees, application fees, and heavy equipment rental fees.

[0006] In the above technical fields, Patent Document 1 discloses a buried object identification technology that generates information about buried objects using underground exploration images taken by a high-frequency electromagnetic radar probe. Patent Document 2 also discloses a technology for detecting buried objects by measuring and comparing the pressures applied to the motors used in test excavation or excavation work using an elevator motor and a rotary motor, and extracting the pressure applied in the vertical direction to the bottom end of a cylindrical tube.

[0008] Methods for determining the type and size of underground rocks and obstacles include non-destructive testing techniques such as underground radar, electrical exploration, ultrasonic exploration, and elastic wave exploration, as well as destructive testing methods such as boring surveys and tunnel surveys. These methods involve surveying the entire land from the surface or analyzing objects extracted from the ground at a different location, and are therefore unable to quickly determine the type and size of buried objects at the test excavation site. Test excavation surveys at construction sites are carried out to construct foundation piles for the construction of buildings, so it is important to determine the type and size of underground obstacles near the designed pile driving locations, but no specific method or system for achieving this purpose has been developed.

[0009] An object of the present invention is to construct a system including an obstacle detection device, an obstacle analysis program, a test drilling survey system, a display terminal, etc. that solves the above-mentioned problems, and to analyze and provide obstacle information.

[0010] The present invention operates a test excavation obstacle analysis system for detecting underground obstacles, comprising an obstacle detection device, an obstacle analysis program, a test excavation system, a display terminal, and the like. The obstacle detection device is most preferably inserted from the surface into a pit created by an excavation machine such as a pole erection vehicle during test excavation work to detect underground obstacles. It is preferably designed as an attachment to the auger (a screw-shaped drilling device at the tip) of the excavation machine such as a pole erection vehicle, but it may also be operated as a separate device. The obstacle analysis program identifies and measures the size of obstacles using data acquired from various waves, currents, etc., and may be a computer program or a comprehensive analysis program equipped with artificial intelligence. The test excavation system preferably stores design drawings and land maps and has the function of developing and displaying land subsurface structure maps into 3D images and 3D models based on data transmitted from the obstacle analysis program. The obstacle analysis program may also have the function of generating 3D image data and 3D model data for land subsurface structure maps.

[0011] According to the present invention, trial excavation surveys and the preparation of trial excavation survey reports can be carried out efficiently based on underground obstacle information analyzed by the trial excavation survey system, and not only can the process proceed smoothly from trial excavation work through obstacle removal to building foundation work and building construction, but it can also provide a trial excavation survey obstacle analysis system and method that reduces unnecessary additional construction costs and additional schedules.

[0013] The following describes an obstacle analysis system for trial excavation according to an embodiment of the present invention. First Embodiment: FIG. 1 is a diagram illustrating the overall configuration of a trial excavation obstacle analysis system according to an embodiment of the present invention. As shown in FIG. 1, the trial excavation obstacle analysis system includes, for example, an obstacle detection device 10, an obstacle analysis program-equipped terminal 20, a trial excavation system-equipped terminal 30, and a cloud server database (DB) 40. The obstacle detection device 10 is an underground obstacle data acquisition device with various detection functions. The obstacle analysis program-equipped terminal 20 is a terminal equipped with a program and artificial intelligence that analyzes underground obstacle data transmitted from the obstacle detection device 10 and generates and organizes physical data such as the type and size of obstacles. The terminal 20 is equipped with a computing unit, a memory unit, and various communication functions and other necessary functions. The trial excavation system-equipped terminal 30 is equipped with a computing unit, a memory unit, and an image display function, and has the function of organizing and integrating obstacle information based on the data transmitted from the obstacle analysis program-equipped terminal 20. However, the system does not need to be a specific device and may be implemented as a cloud system. The cloud server DB 40 can store and accumulate data from each device and enable data access from a remote headquarters, etc. Furthermore, by incorporating artificial intelligence into the cloud server DB 40, it can be constructed as a highly secure system that can be accessed from anywhere.

[0014] The obstacle analysis program-installed terminal 20 and the exploratory survey system-installed terminal 30 may be smartphones, etc. The cloud server DB 40 is realized by a server operated by the operator of the exploratory survey obstacle analysis system.

[0015] The terminal 30 equipped with the exploratory survey system is accessed by the obstacle detection device 10 and the terminal 20 equipped with the obstacle analysis program via a direct cable connection or a network.

[0016] The obstacle analysis program-equipped terminal 20 accesses the cloud server DB 40 and acquires from the cloud server DB 40 information corresponding to the display request from the exploratory survey system-equipped terminal 30 .

[0017] The obstacle detector 10 is inserted into an excavation pit and is an obstacle measurement device that uses electromagnetic waves, ultrasound, magnetic fields, electric currents, etc. to identify the type of obstacle and measure, record, and transmit numerical values ​​such as the size of the obstacle.

[0018] The following explanation is based on generalized terminology. The terminal is preferably a mobile terminal, and can be a smartphone, PC, or other device. The terminal has a means (function) for sending and receiving the obstacle information (including various data below). For example, it has a security function such as personal authentication of the person operating the terminal (field workers, headquarters employees, etc.).

[0019] As a specific example, it is applied to check terminal operators, and the worker's attributes (face, name, age, license, etc.) are authenticated. The authentication information is sent to and stored on a cloud server by the drilling obstacle analysis system. The ID and password generated by each worker are registered and used as login information for accessing the system.

[0020] The equipment checks confidentiality, qualifications, etc. by combining IDs, PIN numbers, etc., and using specified operations and functions.

[0021] As an example, data can be sent and received between the cloud server and each device for checking.

[0022] The present invention improves work efficiency by shortening the time and reducing costs by integrating data on the detection and removal of underground obstacles during test excavation surveys. While it is used for test excavation surveys in the construction industry, it is not limited to archaeological surveys, geological surveys, earthquake surveys, etc. It may also be useful for saving lives in the event of a collapse in tunnel construction, etc., and can be used for other systems.
