However, in these conventional techniques, in the method of mixing and stirring the soil improvement material with a stirring blade, improving the ground and constructing piles, at each depth, the blade cutting number of the stirring blade in a unit length and the soil improvement material It is not possible to simultaneously display the injection amount of In today's ground improvement, the quality specified in the design is required to satisfy the number of blade cuttings and the amount of injection at the same time. That is, it is required to uniformly stir a set amount of soil improvement material with the set blade cutting times.

However, in these data display methods, it is difficult for operators of soil improvement machines who actually operate heavy machines or construction managers to see the display of data only at a site where construction is progressing from moment to moment. It is not possible to judge the quality of ground improvement pillars. Ground improvement materials such as cement start hardening immediately after construction, and if the design specifications are not met in terms of quality, etc., it is necessary to immediately take countermeasures such as re-construction at the site.
The present invention achieves the following objects due to the conventional problems as described above.

FIG. 1 is a table showing pile construction data according to an embodiment of the present invention. FIG. 2 is a display example in which the pile construction data of FIG. 1 is displayed in a three-dimensional diagram.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a table showing pile construction data according to an embodiment of the present invention. The pile construction data in FIG. 1 is data for two piles, pile number 1 and pile number 2, and is an example of a depth of 0 to 7.4 m. In this example, the 0.0 to 1.0m section is dry moat (not subject to ground improvement) and the maximum depth is 7.4m. The section flow rate (L/m) indicates the injection amount of the soil improvement material per 1m in the depth direction of the stirring blade. The quality of the injection amount of the soil improvement material is maintained by determining an appropriate predetermined amount before construction according to the ground. The section blade cutting frequency (times/m) indicates the blade cutting frequency per 1 m in the depth direction of the stirring blade. The injected soil improvement material must be stirred and mixed uniformly. The number of section blade cutting times (times/m) is one of the numerical values for ensuring whether the soil improvement material is uniformly stirred and mixed.

FIG. 2 is a display example in which the pile construction data of FIG. 1 is displayed in a three-dimensional view. It is indicated by a cylinder corresponding to the pile diameter and maximum depth, and two pieces of data, the section flow rate (L/m) and the number of section blade cuts (times/m), are displayed on the side of the cylinder at the same time. The section flow rate (L/m) indicates the ratio of the section flow rate (L/m) to the target value with different colors, and the section blade cutting times (times/m) indicates the section blade cutting times (times/m). Depending on the ratio to the target value, the color that represents the section flow rate is expressed by the size of the width that is filled. In the design specifications of the ground improvement of the embodiment of the present invention, the section flow rate (L / m) has a lower limit of 50 and an upper limit of 300, and the number of section blade cuts (times / m) has a lower limit of 50 and an upper limit. This is an example when the value is 200.

The section flow rate (L/m) indicates whether or not the section flow rate (L/m) is appropriate by filling in color. That is, when the section flow rate (L/m) is at the lower limit, red is RGB (255, 0, 0), and when it is at the upper limit, green is RGB (0, 255, 0), and the intermediate value Yellow is displayed in RGB (255, 255, 0) at the time of dry moat, and Blue is displayed in RGB (0, 0, 255) at the time of dry moat. If the lower limit value is red, the upper limit value is green, and the intermediate value is yellow, the ratio of the section flow rate (L/m) to the target value can be visually and intuitively understood, which is preferable. Of course, different colors may be used for the lower limit value, upper limit value, and intermediate value. The numerical value that determines the color of the section flow rate (L/m) is calculated by converting from 0 to 1, with 0 being the lower limit value and 1 being the upper limit value. R1 is the numerical value that determines the color of the section flow rate (L/m), L is the actually measured section flow rate (L/m), Lmin is the lower limit of the section flow rate (L/m), and the upper limit of the section flow rate (L/m) If the value is Lmax,
R1=(L−Lmin)/(Lmax−Lmin)
Calculate with If the calculated value is less than 0, it is set to 0, and if the calculated value is greater than 1, it is set to 1.

For example, if the upper limit Lmax of the section flow rate (L/m) is 300 (L/m), the lower limit Lmin is 50 (L/m), and the measured value L is 50 (L/m), R1 = 50 -50/300-50=0.0, which is displayed in red. When the measured value L is 300 (L/m), R1=300-50/300-50=1.0 and is displayed in green. When the measured value L is 175 (L/m), R1=175-50/300-50=0.5 and is displayed in yellow. If the numerical value of R1 is a numerical value other than 0.0, 0.5 and 1.0, it is displayed in a color between red, yellow and green in proportion to the magnitude of the numerical value. That is, when the numerical value of R1 is between 0.0 and 0.5, it is displayed in a color between red and yellow in proportion to the magnitude of the numerical value. Also, when the numerical value of R1 is between 0.5 and 1.0, it is displayed in a color between yellow and green in proportion to the magnitude of the numerical value. Also, in the dry moat section with a depth of 0.0 to 1.0 m, it is not determined whether or not the section flow rate and section blade cutting frequency have reached the target values, and are displayed in 100% blue.

Under these conditions, the three-dimensional diagram 1 of pile number 1 in FIG. All of them are blacked out, and it can be intuitively judged at a glance that the section flow rate (L/m) and section blade cutting frequency (times/m) are normal and the ground improvement is completed. That is, in the three-dimensional drawing 1 of pile number 1 in Fig. 2, the section from 0.0 to 1.0 m in depth is the dry moat section, so it is displayed in blue, the section from 1.0 to 3.0 m in depth is displayed in yellow, and the depth is 3. The section from 0 to 7.0m is displayed in red, and the section from 7.0 to 7.4m in depth is displayed in yellow with all sides of the cylinder painted out.

On the other hand, in the three-dimensional drawing of pile number 2 in Fig. 2, the middle part (red) from a depth of 1.0 m to a depth of 6.0 m is a striped pattern with white markings in the width direction. be. The striped pattern in the three-dimensional drawing 2 of this pile number 2 indicates that the number of section blade cuts (times/m) is insufficient. That is, the length of the white display in the width direction indicates the insufficient number of section blade cutting times (times/m). The longer the width of the white display, the greater the ratio of the shortage of the number of section blade cuts (times/m).

Details of the display principle of the striped pattern in the three-dimensional drawing 2 of the pile number 2 are shown in FIG. 3(a). That is, the display of the ratio of the section blade cutting frequency (times/m) to the target value is displayed by filling in the color representing the section flow rate (L/m). The numerical value of the ratio to the target value of the section blade cutting times (times/m) is converted to a number from 0 to 1, with 0 when the section blade cutting times (times/m) is at the lower limit and 1 when it is at the upper limit. to calculate. R2 is the numerical value that determines the ratio of the number of times of blade cutting in a section (times/m) to the target value, V is the number of times of actually measuring the number of times of blade cutting in a section (times/m), Vmin is the lower limit of the number of times of blade cutting in a section (times/m), If Vmax is the upper limit of the blade cutting frequency (times/m),
R2=(V−Vmin)/(Vmax−Vmin)
Calculate with If the calculated value is less than 0, it is set to 0, and if the calculated value is greater than 1, it is set to 1.

For example, when the upper limit value Vmax of the section blade cutting times (times/m) is 200 (times/m), the lower limit value Vmin is 50 (times/m), and the measured value V is 100 (times/m) (pile number 2 depth 1.0 to 4.0 m, pile number 2 depth 5.0 to 6.0 m), R2 = 100-50/200-50 ≈ 0.33, 33% is filled with color, the rest In the method of FIG. 3(a), it becomes blank in the width direction. In addition, when the measured value V is 73 (times/m) (pile number 2 depth 4.0 to 5.0m), R2 = 73-50/200-50 ≈ 0.15, and 15% is color It is filled, and the rest is left blank in the width direction. That is, when the section flow rate (L/m) is red, it is displayed in a red-white striped pattern in which red is 33% or 15% and the rest is white. In the three-dimensional diagram 2 and FIG. 3( a ) of the stake number 2 in FIG. 2 , the depth of 1 m is divided into four and displayed with four red and white striped patterns of the same width in order to enhance the visual effect. This is an example of In the section from 7.0 to 7.4 m in depth, R2 = 0 because the measured value V of pile number 2 is 0 (times/m), and all are white. In other words, it is possible to judge whether the section flow rate (L / m) is appropriate or not by the type of color, and it is possible to intuitively judge whether the number of section blade cuts is appropriate or not by the size of the stripe pattern, so the quality of the ground improvement pillar can be immediately determined. It becomes possible to judge

On the other hand, the display example of FIG. 3(b) is an example of display in a striped pattern with a white display sandwiched in the depth direction (vertical direction in FIG. 3(b)). That is, in the above calculation example, the upper 33% is painted in red, and the rest is left blank in the vertical direction and displayed in a red and white striped pattern. The vertical length of the white display indicates the insufficient number of section blade cuts (times/m). The longer the white display, the higher the rate of shortage of the number of section blade cuts (times/m). In the graphical representation method of pile construction data of the present invention, the injection amount of soil improvement material and the number of blade cuttings can be displayed simultaneously in the figure for each depth, so if the design specifications are not met, measures such as re-construction can be immediately taken. It can be done on site.

Although the embodiments of the present invention have been described above, the present invention is not limited to these embodiments. For example, in the embodiment described above, the pile construction data is displayed in a three-dimensional diagram, but it may be displayed in a two-dimensional diagram. Further, in the above-described embodiment, the excess or deficiency of the injection amount is displayed according to a plurality of predetermined different colors, but it may be indicated by monochrome shading.
