Description

  The present invention relates to an electronic system for a boring core obtained by a boring survey which is one of geological surveys.

  When conducting geological surveys for civil engineering structures or building structures, geological surveys, geophysical exploration, drilling surveys, indoor soil tests, etc. are generally performed.

  In geological surveys, it is fundamental to observe the geological situation with the naked eye on the outcrop of the site, and the geological situation in the ground can be estimated to some extent from the strike and inclination of the stratum. Geophysical exploration is intended to grasp the geological condition from the ground surface or borehole using physical methods such as elastic waves and specific resistance, and should be used effectively as a method for obtaining engineering parameters of the ground. Can do.

  However, geological surveys are limited to the ground surface and can only obtain information by observing discontinuous outcrops, and geophysical exploration is effective as an engineering parameter, but it is actually distributed in the ground. There is a disadvantage that the geology cannot be seen with the eyes.

  On the other hand, in the boring survey, it is possible to actually observe the geological condition in the ground by collecting a predetermined cylindrical body 10 as shown in FIG. Classification of rock mass based on the condition of the core 10 collected, understanding of mechanical characteristics by laboratory tests of the core 10 or determination of stratigraphy based on geological surveys using the core 10 (actually multiple cores) It can be positioned as the only research method for directly investigating deep geology.

  Therefore, a boring core is very important as a basic material for designing and constructing structures, etc. for business clients, and it should be stored semi-permanently if it is more important for about 5 to 10 years. There is.

  In particular, rock cores are often stored for a long time and repeatedly observed for various laboratory tests and various purposes. For this reason, it is required to preserve the state at the time of collection as long as possible.

  Therefore, the geological surveyor generally supplies such a boring core 10, 10,... In a wooden core box 20 as shown in FIG.

  For example, as shown in the figure, the core box 20 has five storage spaces 22a to 22e by four partition plates 21a to 21d in a box 21 having a predetermined depth in which the boring cores 10, 10,. The boring cores 10, 10... For each survey point (survey position) can be stored and stored in each of them.

  A lid body 23 is provided on the rear end side of the box body 21 through a hinge part so as to be openable and closable, and transport handles 24 and 24 are provided on the left and right side parts.

  These boring cores 10, 10... Are arranged as simply as possible based on certain rules, and the boring cores 10, 10. Must be organized and organized.

  Therefore, in general, a label 25 describing the following items and corresponding contents is attached to one side of the box body 21, for example.

Construction subject ×××××
Survey position XXX Boring No. 〇 Depth OOm-OOm
Specimen box serial number 〇 of 〇, company name ×××××
And usually, a picture of each of the boring cores 10, 10... In the core box 20 is taken.

When taking pictures of the cores 10, 10..., Prepare a blackboard that describes the contents of the core box 20 appropriately, and a color chart for the three primary colors for color misregistration. It is necessary to shoot under conditions that can be accurately determined. If necessary, it is necessary to wet the surface of the dried core 10, 10... Or to take a picture in the shade when exposed to direct sunlight. Is taken from a position where is perpendicular, and it is necessary to arrange so that the core box 20 is not deformed into a trapezoid in the photographed photograph (see, for example, the description of Prior Art Document 1).

  However, at least one conventional core box 20 is required for each survey position in the survey target area, and a considerable number of core boxes are required for only one survey operation. Moreover, since the number increases every time geological survey work occurs, storage space in the core warehouse, disposal of old cores and core boxes, etc. for geological survey orderers as well as geological surveyers Is a problem.

  In addition, in the current storage method of carrying in and storing the core box in the warehouse, it becomes difficult to extract the target core box when it becomes necessary to check again, and it is equivalent to carrying out. There is a problem of requiring manpower.

  In addition, taking a picture of the core as described above, it is difficult to take a picture of the core stored in the core box with the lid as described above, by fixing the camera at a right angle to the core box surface Appropriate photography is possible only with the predetermined width surface at the center of the upper half circumferential surface, and the contents of the rod-shaped core cannot be photographed.

  Therefore, it cannot be said that such a photograph itself is sufficient for use as geological data for survey analysis or reconfirmation.

  The present invention has been made to solve such a problem. The above-described boring core is converted into electronic data by a predetermined means so that it can be delivered electronically to a survey ordering company, and is manageable. It is an object of the present invention to provide an electronic system for a boring core that can be stored well and can be freely and efficiently taken out and used as needed.

  In order to solve the above-described problems, the present invention is configured with the following effective problem solving means.

(1) First problem solving means The first problem solving means of the present invention converts a boring core, which is a geological sample obtained by a boring survey, into electronic data by a predetermined image processing means, and converts it into the same electronic data. The boring core data is delivered or stored in a state where it is recorded in a predetermined recording means in a state where it can be reproduced by the image reproducing means.

  According to such a configuration, the core data of the boring core read by the imaging means such as a scanner is rotated as an image and a stereoscopic image on an electronic processing processor equipped with an image monitor such as a personal computer. The whole can be observed.

  Then, the geological surveyor delivers the boring core data, which is the geological survey data, in the form of an electronic core box by DVD or the like, while the business orderer is an electronic core warehouse that can store a large number of the electronic core boxes. You will be able to store it without taking any place.

  Therefore, delivery of cores, observation of cores, and storage of cores are easy and efficient, and it can be easily confirmed and used by many parties including consultants who design using them. Significant reduction can be achieved.

(2) Second problem solving means The second problem solving means of the present invention converts a boring core, which is a geological sample obtained by a boring survey, into electronic data by a predetermined image processing means and observes various physical properties. The boring core data such as a columnar diagram converted into the electronic data together with the various physical property observation results is recorded in a predetermined recording means that can be reproduced by the image reproducing means, and then delivered or stored.

  According to such a configuration, the core composition of the boring core at a predetermined survey point read as an image by an image processing means such as a scanner is displayed on a computerized processor including an image monitor such as a personal computer. Various physical properties can be observed with an image, and the entire image can be observed.

  Then, the geological surveyor delivers the boring core data, which is the geological survey data, together with the observation data to the geological ordering contractor as an electronic core box (visual column diagram with numerical data) on a DVD or the like, The survey business orderer can store the electronic core box without taking any place in the electronic core warehouse that can store a large number of the electronic core boxes.

  Therefore, delivery of the core, observation of the core, storage of the core is easy and efficient, and by unifying the core photo and columnar diagram, many stakeholders including consultants who design using this can easily confirm, As it becomes available, the core storage warehouse can be significantly reduced.

(3) Third Problem Solving Means According to a third problem solving means of the present invention, in the first or second problem solving means, the boring core data converted into electronic data by the image processing means is two-dimensional. It is characterized in that it can be displayed as an image in either a developed view or a three-dimensional stereoscopic view.

  According to such a configuration, the core composition of the boring core at a predetermined survey point read as an image by an image processing means such as a scanner is two-dimensionally or three-dimensionally processed on an electronic processing processor equipped with an image monitor such as a personal computer. The whole image can be easily observed as a dimensional image.

  Therefore, it is not necessary to open and close the core box, and it is possible to perform a survey analysis that is simple and far more accurate than the conventional one.

(4) Fourth Problem Solving Means According to a fourth problem solving means of the present invention, in the first, second or third problem solving means, the predetermined image processing means rotates a cylindrical boring core. However, it is characterized by having two scanning functions: a scanning function for scanning the entire circumferential surface of the core and a scanning function for scanning the surface of a granular core spread in a plane.

  According to such a configuration, when reading the core composition of the boring core as image data by an image processing means such as a scanner, a scanning function that scans the entire circumference of the core while rotating the cylindrical boring core, for example, the maximum In order to understand the particle size, gravel content, sand content, and fine soil content, the mesh size, for example, 0.75 μm, 2 mm, etc., is used to scan the surface of the granular core laid flat. The image is captured by using an image processing means having two scanning functions including a scanning function with a measurement function, and reconstructed as a three-dimensional image on an electronic processing processor having an image monitor such as a personal computer, The whole can be observed accurately.

  As a result of the above, according to the present invention, the geological survey ordering contractor can be electronically delivered to the geological survey ordering contractor from the geological surveying contractor, while the delivered geological survey ordering contractor can read and store electronically freely. Can be reused accordingly.

  Therefore, not only the geological surveying contractor but also the geological survey ordering contractor are convenient, and the conventional problems described above can be solved reliably.

<Overview of the entire system>
First, the block diagram of FIG. 1 shows an overall system configuration of an electronic system for a boring core according to the embodiment of the present invention.

  In FIG. 1, reference numeral 1 denotes an electronic computer composed of a personal computer including a color monitor 2 such as a liquid crystal display, an operation unit 3 such as a keyboard, and a DVD player 4 capable of writing and reading. It is a processing processor.

  The electronic processing processor 1 further includes an electronic image (see FIG. 6) of divided pieces 10a to 10e divided into a plurality (five) of a rock core 10 (see FIG. 9) having a stable rod-like structure described later. A first scanner 5 for photographing (a) to (e)) and an electronic image (FIGS. 7A and 7B) of a soil core 10 ′ that is difficult to form a rod-like structure such as a rock core 10 There are two (or one) large scanners with the second scanner 6 that shoots on a transparent plate for photographing with a wide area, and the first and second scanners 5 and 6 The captured images are respectively input to the electronic processing processor 1 as image data.

  For example, as shown in FIG. 2, the first scanner 5 has half the diameter of the rock cores 10 a to 10 e divided into a plurality (five) of the same length on the left and right side walls 5 b and 5 c of the main body 5 a. Each of the portions is supported by a pair of front and rear rubber rollers so as to be freely rotatable, while each of the side walls 5b and 5c is rotated by a rotation drive mechanism 5d that is linked by a linkage means such as a belt provided outside one side 5c. Synchronously, it is driven to rotate 360 ° (one rotation) or several divisions.

  Further, a fluorescent lighting device and an imaging device are provided in an inner portion of the upper openable lid 5e (details and illustration are omitted).

  Then, as shown in the drawing, with the plurality of divided rock cores 10a to 10e set so as to be rotatable as described above, the lid 5e is closed, and the rock cores 10a to 10e are 360 ° (or divided). When the fluorescent lighting device on the lid 5e side is turned on and the imaging device is driven, for example, the entire peripheral surfaces of a plurality of rock cores 10a to 10e are sequentially imaged, and finally as shown in FIG. The cylindrical images (a) to (e) are displayed on the screen of the color monitor 2.

  The image data is input to the DVD player 4 and recorded sequentially.

  On the other hand, the second scanner 6 includes a lid 6b that can be opened and closed similarly to the first scanner 5, and a main body 6a, and a fluorescent lighting device and an imaging device (details and illustration are omitted) inside the lid 6b. Although it is configured, a glass surface 6d for placing the soil core 10 'is provided on the upper surface on the main body 6a side.

  A transparent plate 6e in which the soil core 10 'is laid flat with a predetermined length and a predetermined width is placed on the glass surface 6d for mounting the soil core in a replaceable manner.

  In this embodiment, the transparent plate 6e and the glass surface 6d on the main body 6a side are 5 m in the same manner as the rock core 10 in the soil core 10 ′ in the state of the core tube. The length portion of the core tube is formed to have a left and right length and a depth width dimension that can be spread about 3.14 times the diameter of the core in the core tube state.

  When photographing, a transparent plate 6e in which the soil core 10 'extracted from the core tube is laid flat with a predetermined thickness is set on the glass surface 6d on the main body 6a side, and the lid 6b is closed. Then, the fluorescent lighting device and the imaging device are driven to capture a planar image.

  In this case, as described above, the horizontal dimension (length) of the glass surface 6d at the top of the main body 6a is set to 1/5 of the 5 m length of the soil core 10 'in the core tube state, which is the standard in the standard. It corresponds to the divided 1 m length, and it is photographed five times.

  Then, the two planar images shown in FIGS. 7A and 7B photographed twice are connected and integrated later in the up and down direction to form a 3D shape in a roll shape, and finally a cylinder as shown in FIG. A body-shaped core image 10 ′ is assumed.

  Reference numeral 7a in FIG. 1 is an electronic stethoscope such as a geo-doctor type, for example. The electronic processing processor 1 described above picks up a hitting sound when a predetermined hit is given to the boring core 10 to be analyzed. Is input as sound data, the striking sound is reproduced on the electronic processing processor 1, and the sound waveform is displayed as a graph on the color monitor 2, and the hardness of the rock can be determined by frequency analysis.

  Reference numeral 7b denotes a Mohs hardness tester, which measures the Mohs hardness value of the target boring core 10 and inputs it to the electronic processing processor 1.

  Reference numeral 7 c denotes a Shore hardness tester, which measures the Shore rebound hardness value of the target boring core 10 and inputs it to the electronic processing processor 1.

  Reference numeral 7d denotes an underwater weight measuring device that measures the specific gravity, water absorption rate, and the like of a gravel portion of a target boring core and inputs the measured gravity to the electronic processing processor 1.

  Reference numeral 7e denotes a strength tester, which tests, for example, the uniaxial compressive strength and triaxial compressive strength of the target boring core and inputs the result to the electronic processing processor 1.

  Furthermore, in addition to the above-mentioned various optional data, reference numeral 7f includes, as attached data, reference materials such as how to identify the strata, geological period classification, soil sample photographs, rock sample photographs, and thin rock micrographs of main rock-forming minerals. It is a reference material data supply unit to be input to the electronic processing processor 1.

  Next, FIG. 5 shows the geological data electronics stored in a predetermined storage means such as a DVD as the geological data by converting the composition and characteristics of the “boring core” 10, 10 ′, which is the boring sample obtained as described above, into electronic data. 5 is a flowchart showing the configuration and contents of the computer system “electronic core warehouse”, which will be described in detail below.

  That is, at the start of operation of the computerization system, user registration (use contract) necessary for entering the “electronic core warehouse” is performed (step S1). Next, when it is determined that the user registration has been completed, the geological survey area / district / geological structure zone that is the object of this time is input as the arrangement of the core box. Then, the corresponding sorting shelf NOx is selected and registered among the core box sorting shelves NO1 to NOn that are provided separately for each region / district in Japan or for each geological structure zone in Japan (step S2).

  Next, when the registration of the same shelves is completed, the number of core boxes required (one in each core box) corresponding to the purpose of the boring survey (business name) and the required number of cores according to the same purpose. N is registered (how many core boxes are required as a whole to accommodate the core) (step S3).

  When the registration of the required number N of core boxes is completed, an operation for creating an electronic core box (image) 30 as shown in FIG. 4 is started (step S4).

  The electronic core box 30 is created for each NO of the core box registered with NO added for each region / point. The electronic core box 30 is obtained by assembling the required number N of core boxes 30a to 30f in the vertical direction.

  When the creation of the electronic core box 30 is completed as described above, the operation of digitizing the rock core 10 or the soil core 10 'is subsequently started.

  Here, first, it is determined whether the digitization work is the digitization work of the rock core 10 or the soil core 10 '(step S5).

  As a result, when it is determined that the current digitization work is the digitization work of the rock core 10, first, the rock core digitization work is started in step S 6, and the rod-shaped rock core 10 is removed from the above-described core tube. It is taken out and applied to the first scanner 5 (see FIG. 2) which is an image pickup means. In the subsequent step S7, scanning is performed using the above-described rod-shaped core division scanning method or rotational scanning method.

  As described above, the first scanner 5 used here rotates the rod-shaped rock cores 10a to 10e divided into a plurality of pieces continuously for one rotation at a predetermined rotation angle or at a low rotation speed. However, it is possible to photograph the entire circumferential surface with high accuracy. For example, when the rod-shaped rock core 10 to be photographed taken out from the core tube is about 5 m, from the upper end side. The image is divided every 1 m and photographed simultaneously for five lines, the curved portion is corrected by image processing, and each of the image data is sequentially stored in a predetermined storage means as first to fifth developed images.

  Next, by sequentially connecting the first to fifth developed images stored in the predetermined storage means, one developed view (for 5 m) is created and continuous core formation in the depth direction is achieved ( Step S8).

  Further, subsequently, the one developed image is rolled 360 ° to finally form a cylindrical three-dimensional image 10 shown in FIG. 6 (step S9).

  The developed image and the three-dimensional image here are stored in a form that can be read out and monitored by a personal computer as necessary.

  Thereafter, the report of the result of the geological appraisal for the rock core 10 is folded into a three-dimensional image and stored (step S10).

  Furthermore, when there is a weak part (for example, a crush zone, a seam, etc.) partially in the said rock core 10, the enlarged image of the weak part is also created and attached (step S11).

  Finally, various physical property observation results are collected and each of them is digitized (step S12).

  As the various physical property observation results mentioned here, for example, the following are adopted.

(1) Columnar diagram Columnar diagram created as a survey report (2) Electronic digitization of impact sound Using a geo-doctor electronic stethoscope, the impact sound is reproduced on a personal computer, and a graph is displayed and frequency analysis is performed.
(3) Computerization of Mohs hardness value The hardness is indicated by the Mohs hardness value of the Mohs hardness test. (4) Computerization of Shore rebound hardness. The hardness is indicated by the Shore rebound hardness value of the Shore rebound hardness test. (5) Rock physics Electronic properties of pebbles Shows specific gravity of gravel (measurement of weight in water), water absorption test results, etc. (6) Computerization of rock mechanical properties test results Shows results of uniaxial compressive strength and triaxial compressive strength tests, etc. (7) Collection of other reference materials ・ How to identify geological formations ・ Division of geological period ・ Flame micrographs of major rock formation minerals, etc. Finally, check the number n of the core boxes actually processed above and set the above It is determined whether or not processing of only the value N has been completed (step S13). As a result, if it is determined as YES, it is determined that the electronic processing for all the core boxes N has been completed, and using the DVD player 4, the various electronic data stored in the electronic core box 30 are set as one set on the DVD. Download and enable electronic delivery (step S14).

  On the other hand, when it is determined that the core data type (step S5) is not the rock core 10 but the soil core 10 ', the boring core is crushed into a granular shape or a powder shape, and another imaging means is used. The image is picked up by a certain second scanner 6 and converted into electronic data (imaged) (step S15).

  In this case, the soil core data includes a Raymond sampler sample (N-value test sample) and a sample other than the Raymond sampler.

  Therefore, it is first determined in step S16 which of them is, for example, in the case of a Raymond sampler sample, as shown in (a) and (b) of FIG. Each of the two-dimensional state and the three-dimensional state scan images is created (step S17).

  Then, the data (results) obtained by conducting the physical / mechanical test of the soil core is converted into electronic data (step S18).

  And after that, the number of core boxes n is checked in the same manner as in the case of the rock core 10 (step S13), and when the processing of all the number N of core boxes is completed, the above-mentioned is performed so that electronic delivery is possible. The soil core data converted into electronic data is downloaded to a DVD and the work is completed.

  On the other hand, in the case of a sample other than the Raymond sampler, it is determined in step S19 whether or not it can be disturbed (disturbed). If not disturbed, the rod-shaped core 10 'taken from the core tube is put in an acrylic tube or the like. Then, a three-dimensional image as shown in FIG. 8 showing the soil quality of the rod-shaped core is formed while being rotated by the transparent cylindrical rod-shaped scan method or the divided scan method (step S20). On the other hand, what can be disturbed is imaged using the above-described pad spread scan analysis method. Then, it is formed into a three-dimensional image as shown in FIG. 8 (step S17).

  Then, the data (results) obtained by performing the physical / mechanical test on the soil core 10 'in the same manner as described above is digitized (step S18).

  And after that, the number of core boxes n is checked in the same manner as in the case of the rock core 10 (step S13), and when the processing of all the number N of core boxes is completed, the above-mentioned is performed so that electronic delivery is possible. The digitized soil core data is downloaded to the DVD and the work is finished (step S14).

  In the control flow described above, the transparent cylindrical bar scan method or the divided scan method in step S20 is not necessarily employed.

  Reference numeral 1 denotes an electronic processing processor, 2 a color monitor, 3 an operation unit, 4 a DVD player, 5 a first scanner, 6 a second scanner, and 30 an electronic core box.
