Hereinafter, embodiments of the present invention will be described using the drawings. The same reference numerals are given to the same components in the drawings, and the description will not be repeated.

  FIG. 1 schematically shows a configuration example of a branch anchor placement system according to an embodiment of the present invention. In the branch anchor placement system 1 shown in FIG. 1, a branch anchor 40 is installed on the ground 100. The branch anchor 40 serves as a “bar” that anchors the power pole 200 to the ground 100 in order to generate a branch tension that opposes the wire tension that the power pole 200 receives.

  The branch anchor placement system 1 includes a branch anchor placement tool 10, a camera 20, and a geological data measurement device 30. In addition, in FIG. 1, the description of the worker who operates the branch line which connects the branch line anchor 40 and the electric pole 200, and the tool 10 for setting a branch line anchor is abbreviate | omitted.

  The branch anchor placing tool 10 includes an impact load measurement load cell 11 and a target 12 for inputting image data, and places a branch anchor 40 on the ground 100. The branch anchor placement tool 10 is configured of, for example, an electric hammer breaker. Note that placing means, for example, applying an impact load by an electric hammer breaker to the branch anchor 40 and installing the branch anchor 40 in the ground 100.

Impact load measuring load cell 11, for example, using a strain gauge, it is possible several kgf / cm ² ~200kgf / cm ² about the measurement of the impact load (Reference 1: Osamu Nakano, three others, "impact load measurement Trial manufacture of load cells for the purpose of the study, Proceedings of the Japan Society of Civil Engineers No. 453 / VI-17, pp. 155-161 (September 1992)). The load cell 11 for impact load measurement is arrange | positioned in series in the transmission direction of the impact force which the electric hammer breaker generate | occur | produces.

  The target 12 is disposed at any position on the side surface of the electric hammer breaker (the branch anchor placing tool 10) to make it easy to identify the change in the vertical position of the electric hammer breaker. The vertical position of the branch anchor placing tool 10 changes depending on the placement depth of the branch anchor 40 to be placed. That is, if the installation position of the branch line anchor 40 becomes deep, the branch line anchor placing tool 10 approaches the ground surface (the surface of the ground 100).

  The vertical position of the branch anchor placement tool 10 can be obtained from image data obtained by imaging the target 12. For example, reference 2 (http://WWW.nobby-tech.co.jp/3d/venus3d.html) or reference 3 (http://WWW.yti.co.jp) is used as the image data including the target 12. The position of the target 12 can be determined (measured) by analyzing using the technology disclosed in /vbm/index.shtml).

  The camera 20 acquires image data including the load cell 11 for impact load measurement. The camera 20 is a general digital camera. The camera 20 is mounted on a tripod (not shown) and acquires image data of the installation site of the branch anchor 40 including the branch anchor placing tool 10.

  The geologic data measurement device 30 obtains output data of the load cell 11 for measuring impact load, determines the placement depth of the branch anchor 40 from the position of the target 12 in the image data obtained by the camera 20, and Output data of the impact load measurement load cell 11 is correlated and recorded. The combination of the output data of the load cell 11 for shock load measurement and the placement depth recorded becomes geological data representing the quality (strength) of the ground 100.

  According to the branch line anchor placement system 1 described above, quantitative geological data can be acquired by a simple and inexpensive method.

  Subsequently, the operation of the branch anchor placement system 1 according to the present embodiment will be described in more detail.

(How to install a branch anchor)
Here, the installation method of the branch line anchor 40 is demonstrated.

  As shown in FIG. 1, the branch line anchor 40 is constituted by a plurality of members such as a guide plate 41, a resistance plate body 42, and a stabilizer plate receiver 43. Each member is made of plate-like structural steel. In addition, in FIG. 1, the description of a stabilizer and a branch wire rod is abbreviate | omitted.

  The guide plate 41 is a bow-shaped plate. The resistance plate body 42 is a beak-shaped plate integrally movably integrated with an end of the guide plate 41 on the ground 100 side centering on the end. At an end of the resistance plate 42 on the side of the guide plate 41, a stabilizer receiver 43 into which a stabilizer integrated later is inserted is formed so as to form a substantially horizontal surface with respect to the ground 100.

  A worker (not shown) digs a hole 101 about 20 cm deep in the ground 100. Next, the worker pierces the end of the hole 101 with the tip of the beak of the resistance plate body 42. In this case, the end of the guide plate 41 on the opposite side to the ground 100 is the direction of the utility pole 200, and the stabilizer 43 is approximately horizontal to the ground 100.

  Then, the operator applies the tip end of the branch anchor placing tool 10 to the stabilizer 43 and applies an impact load to the stabilizer 43 so that the upper end of the stabilizer 43 reaches the bottom of the hole 101. The anchor 40 is driven into the ground 100.

  Next, a driving cylinder (not shown) is placed on the stabilizer plate holder 43, and an impact load is applied to a driving rod (not shown) inserted in the driving cylinder with the branch anchor driving tool 10, and the upper end of the guide plate 41 is Drive the branch anchor 40 until it is approximately 10 cm below ground level.

  Next, a stabilizer (not shown) is fitted on the upper portion of the guide plate 41, and an impact load is applied to the rear end of the stabilizer via the driving rod for the anchor anchor placement tool 10 through the driving rod. Until it is fixed against the stabilizer plate holder 43. The cross section in the direction orthogonal to the driving direction of the stabilizer is a concave shape. The stabilizer is fitted with the guide plate 41 in the concave portion and is driven along the guide plate 41.

  Next, the end of the guide plate 41 is lightly tapped so as to fall in the direction of the utility pole 200, and the direction is adjusted to the angle of the branch line.

  Next, a branch wire rod is attached to the end of the guide plate 41, and the branch wire anchor 40 and the electric pole 200 are connected via the branch wire and the branch wire rod.

  FIG. 2 is a view schematically showing the branch anchor 40 installed as described above. As shown in FIG. 2, the resistance plate 42 and the stabilizer 44 installed on the ground 100 cause the branch wire 46 to generate a branch tension in the opposite direction to the wire tension. The branch line tension is a force generated on the branch line 46 connecting the utility pole 200 and the branch line anchor 40 and the branch line rod 45.

  The casting depth of the branch anchor 40, that is, the depth of the branch anchor 40 in the ground 100 is the depth obtained by accumulating the amount of change of the position of the target 12 of the branch anchor casting tool 10 for casting the branch anchor 40 Length). The relationship between the placement depth and the impact load required to place the branch anchor 40 can be geological data representing the quality (strength) of the ground 100.

  Next, the geological data measurement device 30 will be described.

(Geological data measuring device)
First Embodiment
FIG. 3 is a block diagram showing an example of a functional configuration of the geological data measurement device 30 according to the first embodiment of the present invention. The geological data measurement device 30 includes a placement depth measurement unit 301, an impact load acquisition unit 302, and a geological data storage unit 303. The geological data measurement device 30 can be configured as an integrated computer including storage means such as a CPU, a ROM, a RAM, and a hard disk, for example.

  FIG. 4 is a flowchart showing the processing procedure of the geological data measurement device 30. The operation of the geological data measurement device 30 will be described with reference to FIGS. 3 and 4.

  Geological data measurement device 30 starts operation, when output data is generated in load cell 11 for impact load measurement by impact load generated by branch anchor placing tool 10 (YES in step S1). The operation starts, for example, when the amplitude of the output data of the impact load measurement load cell 11 exceeds a threshold.

  The placement depth measurement unit 301 acquires image data including the branch anchor placement tool 10 from the camera 20 (step S2). The camera 20 may continuously capture an image, or may capture an image at the moment when the amplitude of the output data of the impact load measurement load cell 11 exceeds a threshold. The placement depth measurement unit 301 acquires the above-described image data corresponding to the impact force generated by the branch anchor placement tool 10.

  Then, from the acquired image data, the position of the target 12 which changes as the branch anchor 40 is placed is determined. The position is determined by processing image data including the target 12 with, for example, three-dimensional measurement software. The casting depth measurement unit 301 measures the casting depth of the branch anchors 40 by accumulating changes in the position of the target 12 (step S3).

  The impact load acquisition unit 302 acquires the impact load at the time of placing the branch wire anchor 40 according to the placement depth measured by the placement depth measurement unit 301 (step S4). The placement depth usually changes every time the impact force generated by the branch anchor placement tool 10 is applied. Therefore, the impact load acquisition unit 302 acquires the output data every time the amplitude of the output data of the impact load measurement load cell 11 exceeds the threshold.

  The geological data recording unit 303 records the placement depth measured by the placement depth measurement unit 301 in association with the impact load acquired by the impact load acquisition unit 302 (step S5). The recording of the placement depth and the impact load is recorded in a non-volatile memory that holds data without power supply. The non-volatile memory is, for example, a storage unit such as a hard disk or an EEPROM.

  The combination of the recorded impact load and the placement depth is an index that represents the hardness of the ground 100, and becomes geological data of the ground 100. The processing steps of steps S1 to S5 are repeated until the installation of the branch anchors 40 is completed (NO in step S6).

  In addition, the geology may be evaluated by directly comparing the relationship between the impact load and the placement depth measured between different grounds. Alternatively, geological data may be calculated from the relationship between impact load and placement depth.

  Next, a geologic data measurement device 32 according to a second embodiment of the present invention will be described by calculating geologic data.

Second Embodiment
FIG. 5: is a block diagram which shows the function structural example of the geological data measurement apparatus 32 which concerns on 2nd Embodiment of this invention. FIG. 6 is a flowchart showing the processing procedure of the geological data measurement device 32. As shown in FIG.

  Geological data measurement device 32 differs from geological data measurement device 30 (FIG. 3) in that geological data calculation unit 323 is provided. The placement depth measurement unit 301 and the impact load acquisition unit 302 included in the geology data measurement device 32 are the same as the geology data measurement device 30 as apparent from the reference numerals.

  The geological data recording unit 303 calculates geological data based on the placement depth measured by the placement depth measurement unit 31 and the impact load acquired by the impact load acquisition unit 302 (step S25). Geological data calculates, for example, a ground strength evaluation value (Nb value) corresponding to an Nd value obtained by the simplified cone penetration test. The Nd value obtained in the simple cone penetration test is considered to be correlated with the N value in the standard penetration test, and is a value that represents the hardness of the ground 100.

  However, it is Δh = h1-h2 = 10 cm. Nb (h) is a value obtained by dividing the energy value obtained by integrating the output data of the load cell 11 for impact load measurement with the placement depth by the depth difference of the corresponding placement depth. The combination of the impact load, the placement depth, and the calculated ground strength evaluation value may be recorded in the non-volatile memory.

  As described above, the branch anchor placement system 1 according to the present embodiment includes a branch anchor placement tool 10, a camera 20 for acquiring image data including the branch anchor placement tool 10, and a geological data measurement device 30. Quantitative geological data can be acquired with a simple and inexpensive configuration.

  Since the branch anchors 40 are made of structural steel, it is thought that due to corrosion deterioration, there will be times when renewal (such as replacement) will be required within several decades after installation. At that time, the branch anchor placement system 1 according to the present embodiment is extremely useful information which is necessary to determine how much deterioration of the ground load resistance of the branch anchor 40 is progressing in relation to corrosion. Can provide

  In addition, although the geology data measuring device 32 in 2nd Embodiment demonstrated by the example which calculates geology data in the installation site of the branch line anchor 40, it is not limited to this example. At the installation site, only the relationship between the impact load and the placement depth may be recorded, and geological data may be calculated later.

  Also, it is not necessary to measure the installation depth at the installation site. At the installation site, only the change in the position of the target 12 due to the impact load may be recorded in the image data, and the measurement of the placement depth using the three-dimensional measurement software may be performed later.

  Moreover, in said embodiment, although geology data were demonstrated by the example recorded on the geology data measuring devices 30 and 32, it is not limited to this example. Geological data may be recorded in a cloud server created in a cloud environment connected to the geological data measuring devices 30, 32 via a network.

  Moreover, although the tool 10 for anchor wire anchor placement was demonstrated by the example comprised with an electric hammer breaker, it is not limited to this example. The branch anchor placement tool 10 may be configured by a simple hammer. In other words, an impact load may be applied by using a hammer to, for example, a driving rod provided with the load cell 11 for impact load measurement and the target 12.

  Thus, the present invention is not limited to the above-described embodiment, and various modifications are possible within the scope of the invention.

  When the processing unit in the above apparatus is realized by a computer, the processing content of the function that each apparatus should have is described by a program. Then, by executing this program on a computer, the processing unit in each device is realized on the computer. This program can be recorded on a recording medium or provided through a network.

  Each processing unit may be configured by executing a predetermined program on a computer, or at least a part of the processing content may be realized as hardware.
