Description

[Technical field]

[0001] The present invention relates to an obstacle analysis system for exploratory surveys. [Background technology]

[0002] A trial excavation survey is a construction work to check whether there is anything that may affect the construction of a structure at the excavation site before construction work begins. In order to investigate the geology or buried objects underground, the ground is partially excavated prior to construction work to check the location and depth of underground buried objects (rocks, foundations, piles, cavities, waste, gas pipes, water pipes, etc.). Trial excavation surveys are necessary because there is a possibility of a major accident, such as accidentally cutting important infrastructure facilities underground without performing trial excavation work, or causing a large accident, such as subsidence, by placing heavy objects such as heavy machinery on a cavity that has appeared underground without noticing it.

[0003] Trial excavation work is an investigation using construction machinery such as excavators and backhoes to check for the presence of obstacles buried in the soil of a site (for example, waste illegally dumped by the previous owner or construction company, the foundations of previous buildings, structures including piles, or natural objects such as rocks and stones) or cavities. Trial excavation work is a lot of work, requiring the maintenance of expensive construction machinery and waste disposal, so there are currently few contractors willing to take on the job.

[0004] Exploration contractors conduct exploratory surveys in advance to prevent unexpected removal and disposal costs and construction delays if previous building structures or illegally dumped waste are discovered during pile and foundation work. As an example of trial excavation work, an excavator such as a post erection vehicle is used to investigate five locations (the center and four diagonal points) on one of the piles of a planned building to check that there are no obstacles to the pile work, measure the depth of the drilled hole, record the location of any underground obstacles, and submit a trial excavation survey report to the client.

[0005] In a test excavation survey, when an obstacle is hit during drilling with the auger (a screw-shaped drilling device at the tip) of a pole-setting vehicle or other excavator, the auger must be removed and the shape, depth, and type of the obstacle must be investigated from the ground surface using ultrasonic, high-frequency, and other measuring devices. It is desirable to be able to determine the type and size of the obstacle from the data of the measuring device, but a rational method for this determination has not yet been developed. When leftover items are found on the site, if the contract with the seller excludes the responsibility for removing underground obstacles, the construction owner must remove the underground obstacles at his own expense. In most cases, this is not included in the estimated cost of the construction work, and the unexpected expense will have a significant impact on the original construction and construction period. In addition, during pile construction, the piles will interfere with underground obstacles, so the piles must be offset. In order to offset the piles, structural calculations will be performed, and the foundation will become larger. Depending on the scale of the offset, an application for a change in plan may be required. The construction will be suspended until permission for the change in plan is granted, and the pile driver will remain on site, resulting in double or triple unnecessary expenses such as the cost of removing the obstacles + industrial waste disposal cost + foundation increase + design fee + application fee + heavy equipment rental fee.

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

[0007] [Patent Document 1] Patent No. 7145249 [Patent Document 2] JP 2019-157605 A Summary of the Invention [Problem to be solved by the invention]

[0008] Methods for determining the type and size of underground rocks and obstacles include non-destructive testing techniques such as underground radar exploration, electrical exploration, ultrasonic exploration, and elastic wave exploration, as well as destructive testing methods such as drilling 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 it is not possible to quickly determine the type or size of objects buried at the exploratory site. The purpose of test excavation surveys at construction sites is to construct foundation piles for building structures, so it is important to determine the type and size of underground obstacles near the designed pile driving points, 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., which solves the above-mentioned problems, and to analyze and provide obstacle information. [Means for solving the problem]

[0010] In the present invention, a trial excavation obstacle analysis system is operated by an obstacle detection device, an obstacle analysis program, a trial excavation system, a display terminal, etc., in order to detect underground obstacles. The most desirable obstacle detection device is inserted from the ground surface into a pit made by a pole-setting vehicle or other excavator during trial excavation work to detect underground obstacles. It is desirable to design it as an attachment to the auger (a screw-shaped drilling device at the tip) of the pole-setting vehicle or other excavator, but it may be operated as a separate device. The obstacle analysis program identifies obstacles and measures their size using data obtained from various waves, currents, etc., and may be a computer program or a comprehensive analysis program equipped with artificial intelligence. The test drilling system preferably has a function of storing design drawings and land plans, and of developing and displaying land subsurface structure maps into 3D images and 3D models based on data sent from the obstacle analysis program. The obstacle analysis program may also have a function of generating 3D image data and 3D model data for land subsurface structure maps. Effect of the Invention

[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 is also possible to provide a trial excavation obstacle analysis system and method that reduces unnecessary additional work costs and additional schedules.

[0013] Hereinafter, a test excavation obstacle analysis system according to an embodiment of the present invention will be described. First Embodiment FIG. 1 is a diagram showing the overall configuration of a test 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-installed terminal 20, a trial excavation system-installed terminal 30, and a cloud server DB 40. The obstacle exploration device 10 is an underground obstacle data acquisition device having various exploration functions. The obstacle analysis program-equipped terminal 20 is a terminal equipped with a program and artificial intelligence that analyzes the underground obstacle data transmitted from the obstacle detection equipment 10 and generates and organizes physical data such as the type and size of the obstacle, and is equipped with a calculation unit and a memory unit and has various necessary functions such as communication functions. The terminal 30 equipped with the trial excavation survey system is equipped with a calculation unit, a memory unit, and an image display function, and has the function of organizing and consolidating obstacle information using the data transmitted from the terminal 20 equipped with the obstacle analysis program, but it does not need to be a specific device and may be constructed as a cloud system. The cloud server DB40 can store and accumulate data from each device and enable data access from a remote location such as the head office. In addition, by equipping this cloud server DB40 with artificial intelligence, it can be constructed as a highly secure system that can be accessed from anywhere.

[0014] The obstacle analysis program-mounted terminal 20 and the exploratory investigation system-mounted terminal 30 may be a smartphone or the like. The cloud server DB40 is realized by a server operated by the operator of the borehole investigation obstacle analysis system.

[0015] The trial excavation survey system mounted terminal 30 is accessed from the obstacle detection equipment 10 and the obstacle analysis program mounted terminal 20 by direct cable connection or via 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 a display request from the trial excavation 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, ultrasonic waves, 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 examples. The terminal is preferably a mobile terminal, and may be a smartphone, PC, or other device. The terminal has a means (function) for transmitting and receiving the obstacle information (including various data below). For example, it has a security function such as human authentication of the person who operates the terminal (field workers, head office employees, etc.).

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

[0020] The equipment checks confidentiality, qualifications, etc. using a combination of ID, PIN, etc., and specific operations and functions.

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

[0022] The present invention improves work efficiency by shortening time and reducing costs by integrating data on the discovery of underground obstacles during exploratory surveys and removal work. In the construction industry, it is used for exploratory surveys, but it is not limited to archaeological, geological, and earthquake surveys. It can also be used for other systems, such as for saving lives in the event of a collapse during tunnel construction. [Explanation of symbols]
