Hereinafter, each process is demonstrated along a construction order.
In the data creation process, numerical data such as the dimensions of the support ground 2, foundation 3 and U-shaped groove 1, road alignment, longitudinal gradient, cross section, change point coordinates, etc. are extracted from the design book and input to a processing device (not shown). Then, three-dimensional coordinate data such as the horizontal position and height position of various parts is calculated by the processing device. The processing device is a portable tablet including a computer, an input device, and a display device. A calculation program for calculating the three-dimensional coordinate data of the foundation 3 and the U-shaped groove 1 is input and stored in the memory of the computer. The calculation program includes a calculation function for calculating three-dimensional coordinate data of various parts based on numerical data of a design drawing input by an input device to a computer, and an output function for outputting the calculated three-dimensional coordinate data to a display device , To realize. The calculated three-dimensional coordinate data is displayed on a display device. A worker who is working carries a portable tablet, and can check various data on a display device at a construction position. In the present embodiment, the calculation program causes the computer to realize a function of calculating three-dimensional coordinate data such as the excavation position and excavation depth of the construction groove excavated in the planned construction ground 5. With this calculation function, the three-dimensional coordinate data of the construction groove is also calculated.

  In the excavation data calculation process, as shown in FIG. 1, the line 6 is drawn through the planned construction ground 5 before excavation, the mobile station 10 (see FIG. 3) is put on the line 6, and the surface position is determined by the total station 20. This is a step of performing actual measurement and calculating and displaying excavation data of the right and left excavation widths and excavation depths of the line through the processing device based on the design data. The operator pulls the street line 6 at a rough approximate position along the excavation position. Then, the mobile station 10 is placed along the street line 6 at an arbitrary interval, and the horizontal position and height position of each measurement position (position where the mobile station is placed) on the street line 6 are measured. The mobile station 10 is configured by installing a prism 12 on an upper portion of a rod-shaped member 11. The mobile station 10 is compared with a fixed station such as the installation position of the total station 20 to measure three-dimensional coordinates. The total station 20 is preferably installed outside the arrangement curve of the U-shaped groove 1. With this arrangement, the collimation of the prism 12 by the total station 20 is difficult to be blocked.

  In the processing apparatus, the horizontal position and height position of the measurement position on the street line 6 are compared with the three-dimensional coordinate data such as the excavation position and the excavation depth to be excavated on the planned construction ground 5, The left and right width dimensions and the excavation depth dimensions are calculated. The calculated left and right width dimensions W1 and W2 and the excavation depth dimension D are displayed on a display device, and are displayed by marking or the like in the vicinity of the line 6 as the construction planned ground 5.

  As shown in FIG. 3, the excavation process is a process of excavating the planned construction ground 5 with a heavy machine such as a backhoe 7. In the excavation process, excavation is performed based on excavation data (excavation left and right width dimensions and excavation depth dimensions from each measurement position on the street line 6). The worker performs excavation while looking at the excavation data displayed on the planned construction ground 5 or the excavation data displayed on the display device. After excavation, the compaction is performed using the compaction device 8. As a result, the operator can obtain an indication of excavation and can easily perform excavation work with a heavy machine without tension.

  In the excavation surface error calculation step, the mobile station 10 is placed on the excavation surface 5a, the surface position data of the excavation surface 5a is measured by the total station 20, and the excavation surface surface position data is compared with the design data by the processing device. This is a process for calculating construction errors. In the excavation surface error calculation step, an operator places the mobile station 10 at an arbitrary interval along the excavation surface 5a. In the total station 20, the horizontal position and the height position of each measurement position (position on which the mobile station is placed) on the excavation surface 5a are actually measured. The total station 20 has an automatic tracking function, and automatically measures the mobile station 10 at each measurement position by automatic tracking. The surface position data of the excavation surface 5a measured by the total station 20 is transmitted to the processing device.

  In the processing apparatus, the excavation surface construction error is calculated by comparing the surface position data (current value) of the excavation surface 5a with the design data (design value) of the supporting ground 2. Specifically, the design value of the height position at the measurement point is calculated from the design data, and the excavation surface construction error is calculated by comparing the height position (design value) with the current value of the height position. The calculated excavation surface construction error is displayed on the display device.

  The excavation surface adjustment step is a step of performing adjustment excavation of the excavation surface 5a based on the excavation surface construction error. In the excavation surface adjustment process, an operator manually adjusts the height position using a rake or the like. After the excavation surface adjustment step is completed, the excavation surface 5 a is rolled using the rolling device 8. After the excavation surface adjustment step is completed, the excavation surface error calculation step is performed again to confirm that the error has been eliminated.

  The foundation construction process is a process of forming the foundation 3 on the excavation surface 5a as shown in FIG. The basic construction process of the present embodiment includes a crushed stone layer construction process for constructing the crushed stone layer 3a, a base concrete layer construction process for constructing the base concrete layer 3b, and a laying mortar layer laying process for constructing the laying mortar layer 3c. . The basic error calculation step includes a crushed stone layer error calculation step and a base concrete layer error calculation step. The foundation adjustment process includes a crushed stone layer adjustment process and a base concrete layer adjustment process. In this embodiment, the crushed stone layer construction step, the crushed stone layer error calculation step, the crushed stone layer adjustment step, the base concrete layer construction step, the base concrete layer error calculation step, the base concrete layer adjustment step, and the mortar layer laying step are performed in this order. . In addition, each process of a foundation construction process is suitably changed according to the shape of the foundation 3.

  In the crushed stone layer construction step, the crushed stone 3 a is constructed by laying the crushed stone to a predetermined thickness using the backhoe 7, and then the crushed crushed stone layer 3 a is rolled by the rolling device 8. Thereafter, a crushed stone layer error calculating step (basic error calculating step) and a crushed stone layer adjusting step (basic adjusting step) are sequentially performed.

  In the crushed stone layer error calculating step, a crushed stone layer construction error (basic construction error) is calculated using the surface of the crushed stone layer 3a as one of the foundation surfaces. In the crushed stone layer error calculating step, the mobile station 10 is placed on the crushed stone layer 3a, the surface position data of the crushed stone layer 3a is measured by the total station 20, and the crushed stone layer surface position data is compared with the design data by the processing device. This is a process for calculating construction errors. In the crushed stone layer error calculating step, the worker places the mobile station 10 at a predetermined interval along the crushed stone layer 3a. In the total station 20, the horizontal position and height position of each measurement position (position on which the mobile station is placed) on the crushed stone layer 3a are actually measured. The total station 20 automatically performs measurement of the mobile station 10 at each measurement position by automatic tracking. The surface position data of the crushed stone layer 3a measured by the total station 20 is transmitted to the processing device.

  In the processing apparatus, the surface position data (current value) of the crushed stone layer 3a is compared with the design data (design value) of the crushed stone layer 3a, and the crushed stone layer construction error is calculated. Specifically, the design value of the height position at the measurement point is calculated from the design data, and the crushed stone layer construction error is calculated by comparing the height position (design value) with the current value of the height position. The calculated crushed stone layer construction error is displayed on the display device. Then, a crushed stone layer adjustment process (basic adjustment process) is carried out.

  The crushed stone layer adjustment step is a step of adjusting the crushed stone layer 3a based on the crushed stone layer construction error (foundation construction error). In the crushed stone layer adjustment process, workers perform leveling by manpower using rakes and the like. After the crushed stone layer adjusting step is completed, the crushed stone layer 3 a is rolled using the rolling device 8. After completing the crushed stone layer adjustment step, the crushed stone layer error calculation step is performed again to confirm that the error has been eliminated.

  After the crushed stone layer adjustment step, a base concrete layer construction step is performed. In the base concrete layer construction step, the base concrete layer 3b is constructed by placing a formwork (not shown) on the crushed stone layer 3a and placing concrete. The formwork is formed so that the upper end is the same height as the upper end of the base concrete layer 3b.

  In the base concrete layer error calculation step of this embodiment, the base concrete layer construction error (foundation construction error) is calculated using the upper end surface of the formwork as one of the foundation surfaces. That is, the base concrete layer error calculating step and the base concrete layer adjusting step are performed before placing concrete. In the base concrete layer error calculation step, the mobile station 10 is placed on the mold, the surface position data of the mold is actually measured by the total station 20, and the base concrete layer surface position data and the design data are compared by the processing device. This is a step of calculating the layer construction error. In the base concrete layer error calculation step, an operator places the mobile station 10 at a predetermined interval along the upper end surface of the formwork. In the total station 20, the horizontal position and the height position of each measurement position (position on which the mobile station is placed) on the base concrete layer are actually measured. The total station 20 automatically performs measurement of the mobile station 10 at each measurement position by automatic tracking. The surface position data of the base concrete layer measured by the total station 20 is transmitted to the processing device.

  In the processing apparatus, the base concrete layer construction error is calculated by comparing the surface position data (current value) of the mold with the design data (design value) of the base concrete layer 3b. Specifically, the design value of the height position at the measurement point is calculated from the design data, and the base concrete layer construction error is calculated by comparing the height position (design value) with the current value of the height position. The calculated base concrete layer construction error is displayed on a display device. Then, a base concrete layer adjustment process (foundation adjustment process) is carried out.

  The base concrete layer adjustment step is a step of adjusting the formwork based on the base concrete layer construction error (foundation construction error). In the base concrete layer adjustment process, workers adjust the installation height of the formwork. After the base concrete layer adjustment step is completed, the base concrete layer error calculation step is performed again to confirm that the error has been eliminated. Thereafter, concrete is placed in the formwork to complete the base concrete layer construction process.

  Thereafter, a mortar layer laying step is sequentially performed. The laid mortar layer 3c is a portion where the U-shaped groove 1 is installed, and serves to fix the U-shaped groove 1 to the crushed stone layer 3a and to adjust the height. In the laying mortar layer construction step, a mortar is placed on the crushed stone layer 3a to lay a mortar layer 3c having a predetermined thickness. The upper end surface of the mortar layer 3 c is set slightly higher than the design value of the bottom surface height of the U-shaped groove 1.

  As shown in FIG. 5, the structure installation step is a step of installing a U-shaped groove 1 (a road-attached continuous structure) on the foundation 3. In the structure installation step, for example, the U-shaped groove 1 is suspended by a well-known suspension bracket 9 b suspended from the arm tip of the backhoe 7 via a wire 9 a and placed on the foundation 3. The structure installation step is performed before the mortar layer 3c is cured. The U-shaped groove 1 sinks slightly from the upper end surface of the mortar layer 3c due to its weight.

  In the structure error calculation step, the mobile station 10a is placed on the U-shaped groove 1 and the surface position data of the U-shaped groove 1 is measured by the total station 20, and the structure surface position data and the design data are compared by the processing device. This is a process of calculating a construction error. In the structure error calculation step, the prism-attached bracket 13 corresponding to the shape of the road-attached continuous structure (in this embodiment, the U-shaped groove 1) is attached to the U-shaped groove 1 as the mobile station 10a, and measurement is performed.

  The bracket with prism 13 is a dedicated bracket installed in the U-shaped groove 1, and includes a bracket body 13a to which the prism 12 is fixed, a locking portion 13b provided at one end of the bracket body 13a, And a level 14 attached to the upper part of the bracket body 13a. The bracket main body 13 a is bridged between both ends of the upper opening of the U-shaped groove 1. The lower end portion of the locking portion 13 b extends downward and is locked to the widthwise end portion of the U-shaped groove 1. By using such a prism-equipped bracket 13, the positional relationship between the width direction end of the U-shaped groove 1 and the prism 12 becomes constant. Therefore, by measuring the position of the prism 12, the position of the U-shaped groove 1 can be determined. Calculated accurately. That is, the three-dimensional coordinates of the horizontal position and the height position of the U-shaped groove 1 can be grasped. Furthermore, since the bracket 13 with a prism can be mounted and fixed in the U-shaped groove 1, it is not necessary for the operator to hold it down. Therefore, the worker can perform other operations after installing the prism-equipped bracket 13 in the U-shaped groove 1.

  When actually measuring the surface position data of the U-shaped groove 1, the positions of both ends in the longitudinal direction are actually measured in the first U-shaped groove 1 installed, and the second and subsequent U-shaped grooves 1 connected thereto are already installed. The position of the end portion on the side away from the U-shaped groove 1 is actually measured. That is, in the U-shaped groove 1 to be installed first, the prism-attached brackets 13 are installed at both ends in the longitudinal direction to measure the position of the prism 12. In the second and subsequent U-shaped grooves 1, a prism-attached bracket 13 is installed at an end portion on the side away from the installed U-shaped grooves 1 to measure the position of the prism 12. In this way, surface position data including the gradient angle of each U-shaped groove 1 can be measured.

  The surface position data of the U-shaped groove 1 measured by the total station 20 is transmitted to the processing apparatus. In the processing apparatus, the U-groove construction error (structure construction error) is calculated by comparing the surface position data (current value) of the U-shaped groove 1 with the design data (design value) of the U-shaped groove 1. Specifically, the three-dimensional position (design value) of the prism 12 with respect to the position (design value) of the U-shaped groove 1 is calculated from the design data, and the current state of the three-dimensional position (design value) and the three-dimensional position of the prism 12 is calculated. The U-groove construction error (horizontal position and height position error) is calculated by comparing the values. For the U-shaped groove construction error, a deviation direction and a deviation distance from the normal position are calculated. The display device displays the moving direction and moving distance to be corrected.

  Below, the program for performing the said procedure is demonstrated. A moving direction instruction program is input and stored in the memory of the computer of the processing apparatus. The moving direction instruction program is a program for calculating a U-shaped groove construction error and displaying on the display device a moving direction and a moving distance to be corrected, which are derived from the U-shaped groove construction error. The moving direction instructing program selectively displays the moving direction of the road-attached continuous structure on the computer of the processing device according to the direction of the worker who adjusts the installation position of the U-shaped groove 1 (continuous structure with the road). The moving direction display function is realized.

  The workers who adjust the installation position of the U-shaped groove 1 (continuous structure attached to the road) are, for example, a driver (not shown) of the backhoe 7 and 2 located in the vicinity of both ends in the longitudinal direction of the U-shaped groove 1. There are three people with one worker. In FIG. 5, the two workers are located outside, but are not shown in order to illustrate the configuration of the U-shaped groove 1 and the bracket 13 with the prism. The direction of the input worker is the direction of the person holding the portable tablet. In the present embodiment, in FIG. 5, any worker (not shown) near the end of the U-shaped groove 1 holds the portable tablet. The orientation of the worker is based on the starting point side where the installation work is started and the end point side where the installation work is completed in the installation procedure of the U-shaped groove 1. That is, when the worker (person holding the portable tablet) is located on the starting side from the U-shaped groove 1 installed by the worker (person holding the portable tablet), the worker (person holding the portable tablet) installs. When located closer to the end point than the U-shaped groove 1, it is directed toward the starting point.

  In the processing device, the U-groove construction error (horizontal position and height position error) is calculated by comparing the position data from the total station (the construction position of the U-groove 1) with the three-dimensional coordinate data of the design drawing. The The movement direction and the movement distance to be corrected are derived from this error and displayed on the display device. At this time, in the display device, if the display angle of the display image and the orientation of the worker are the same, the movement direction of the display image is the same as the actual movement direction. When the directions are opposite, the moving direction of the display image is opposite to the actual moving direction. When the display angle of the display image is opposite to the worker's direction, the worker can display the moving direction in the reverse direction by pressing a switching button (not shown) provided in the processing apparatus. Specifically, when the moving direction is displayed in characters, for example, the display of “move mmmm to the left” is changed to “mmm mmmm to the right”, and the moving direction is indicated by an arrow. If so, the arrow is highlighted. In other words, the display device can display the left and right directions with reference to the worker viewing the portable tablet, not the displacement position of the U-shaped groove 1 itself, so that the worker can display the U-shaped groove 1 in the displayed direction. Should be moved. Therefore, the worker can accurately perform the correction work without making a mistake in the left-right direction. In addition, when it has shifted | deviated to the front-back direction besides the left-right direction, the front-back direction is also displayed according to the left-right direction. Also in the front-rear direction, the moving direction to be corrected according to the direction of the worker is displayed. Note that the worker may select to leave the moving direction as it is without pressing a switching button (not shown) even when the display angle of the display image and the orientation of the worker are opposite. .

  The structure adjustment step is a step of adjusting the installation position of the U-shaped groove 1 based on the U-shaped groove construction error. In the structure adjustment process, the level of the left and right is also adjusted by the leveler 14 attached to the upper part of the bracket body 13a to ensure the level of the U-shaped groove 1. The error is corrected by hitting the corner of the U-shaped groove 1 with a plastic hammer (not shown), for example. When adjusting the horizontal position, the side of the U-shaped groove 1 is tapped from the side with a plastic hammer, and when adjusting the height position, the upper part of the U-shaped groove 1 is tapped from the top with a plastic hammer.

  According to the construction method of the road incidental facility according to the present embodiment, the surface position data (current value) is measured and the construction error is calculated at each construction stage of the supporting ground 2, the foundation 3, and the U-shaped groove 1. Since the adjustment work is performed, there is no construction error at each construction stage. Therefore, since construction can be performed with high positional accuracy at each construction stage, construction errors do not accumulate and the positional accuracy of the U-shaped groove 1 can be increased. Thereby, consistency with the pavement surface to be constructed in the subsequent process can be ensured.

  In addition, according to the construction method of the road incidental equipment, various parts such as the supporting ground 2, the foundation 3 and the U-shaped groove 1 are constructed based on the design data. 1 (continuous structure with roads) can be installed. Therefore, the labor and time concerning construction can be reduced.

  Further, in the present embodiment, the street line 6 is drawn on the planned construction ground 5 before excavation, and the surface position of the street line 6 is measured, and the right and left excavation widths and excavation depths of the street line 6 are determined based on the design data. Since the excavation data is calculated and displayed, an indication of excavation during excavation can be obtained. Therefore, excavation work with a heavy machine can be performed easily and with high accuracy without tension.

  In the foundation construction process after the excavation process, the foundation 3 is constructed on the basis of the highly accurate excavation surface 5a. Therefore, the construction work of the foundation can be performed easily and with high accuracy without tension. Further, in the structure installation process, the U-shaped groove 1 is installed based on the highly accurate foundation 3, so that the installation work of the U-shaped groove 1 can be performed easily and with high accuracy without tension.

  As described above, by eliminating the tensioning, it is possible to save labor and time for installing the tensioning, and it is possible to reduce the risk of danger and waste due to the action of the backhoe avoiding the tensioning. Further, the movement of the backhoe 7 is not restricted by the tension. Furthermore, in the case of the tension in the curved portion, it was necessary to shorten the installation pitch of the wooden pile, but according to the present embodiment, since the ready-made U-shaped groove 1 is used also in the curved portion. It can be constructed with the same effort as the straight part.

  Since surface position data of various parts is actually measured using the total station 20 and the mobile station 10, it can be easily and accurately measured. In particular, in the present embodiment, since the mobile station 10 is measured at each measurement position by automatic tracking of the total station 20, the total station 20 only needs to be first installed and started to operate.

  As mentioned above, although the form for implementing this invention was demonstrated, this invention is not the meaning limited to the said embodiment, A design change is possible suitably in the range which does not deviate from the meaning of this invention. For example, in the above-described embodiment, the calculated three-dimensional coordinate data is the position data of the U-shaped groove 1, the support ground 2, and the foundation 3, but is not limited thereto. The calculated position data is appropriately changed according to the type of road-attached continuous structure and the structure of the foundation.

  Moreover, in the said embodiment, although the automatic tracking function of the total station 20 is utilized, it is not limited to this. Any instrument other than the total station may be used as long as it is a surveying instrument having a function capable of automatically tracking the prism and measuring coordinates and sending data to the processing device. Furthermore, when the measuring device does not have an automatic tracking function, an operator may perform measurement work using the surveying device every time the mobile station 10 moves.

  In the excavation data calculation and display step of the above embodiment, the line 6 is drawn through the planned construction ground 5 before excavation, the mobile station 10 is put on the line 6 and the surface position is measured by the total station 20 and based on the design data. In the processing apparatus, the excavation data of the right and left excavation widths W1 and W2 and the excavation depth D of the line 6 are calculated and displayed. However, the present invention is not limited to this. After the mobile stations 10 are sequentially placed along the planned construction ground and the surface position is actually measured by the total station 20, a line may be drawn on the basis of the actually measured values of the measurement points. The street line may be drawn by connecting the measurement points, or may be drawn along the center line of the portion to be excavated. When the street line is drawn along the center line, the center position of the excavation width is calculated from the actual measurement value of the measurement point and the design data.
