Japanese Unexamined Patent Publication No. 6-185067

By the way, when constructing a slope protection work on a slope, for example, the anchor is constructed after the slope construction is performed by spraying mortar, but it is necessary to determine the anchor construction position before the construction of this law frame construction. It becomes.

Conventionally, when determining the construction position of an anchor in this slope protection work, a plan view and a cross-sectional view of the site are created, and a design is made in which the construction position of the anchor is examined based on them.

However, although this anchor construction position is shown in the plan view and the cross-sectional view, it is a two-dimensional drawing and the fine unevenness of the slope is not taken into consideration, so it is accurate on the slope (natural slope) of the site. Therefore, it is not possible to construct as designed. Therefore, in reality, the worker moves on a steep slope with a surveying instrument to determine the construction position of the anchor.

The present invention provides an epoch- making method for constructing a slope structure, which solves the above-mentioned problems.

The gist of the present invention will be described with reference to the accompanying drawings.

Construction position X can be determined.

That is, since it is easy for the operator to imagine the completed state of the slope structure 1 (construction position X of the anchor 2) before the construction, and because it is based on the information of the 3D image according to the topography of the site, the anchor 2 The construction position X of the above can be determined accurately.

Specific examples of the present invention will be described with reference to the drawings.

This embodiment is an anchor construction position display device 10 for displaying the construction position X of the anchor 2 that fixes the slope structure 1 to the slope 3 (ground).

In this embodiment, as the slope structure 1, the first beam member 1A having a length in the vertical direction (one direction) and the second beam member 1B having a length in the horizontal direction (the other direction) intersect each other. The slope protection work to be arranged is adopted, and the area 1'to construct the anchor 2 at the intersection of the first beam material 1A and the second beam material 1B, the first beam material 1A and the second beam material 1B It has an area 1 "where the anchor 2 is not installed at the intersection of the above.

The slope structure 1 is not limited to the slope protection work described above, but is appropriately adopted as long as it has a configuration that exhibits the characteristics of this embodiment, such as an anchor work independent pressure receiving plate, an avalanche countermeasure work, and a rockfall countermeasure work. What you get.

Hereinafter, each component of the present embodiment will be described in detail.

Specifically, the anchor construction position display device 10 is a portable terminal that can be carried in the field such as a smartphone, a tablet PC, a head mount type display, and a glasses type display, and has a display screen 10a, a CPU (computer), and the like. In addition to basic equipment such as a camera, those equipped with various measurement sensors (gyro sensor, accelerometer, GPS sensor, etc.) will be adopted.

Further, this embodiment includes a program for superimposing (fusing) a real space image and a virtual space image (3D image) captured by a camera on the site (real space) of the slope 3.

This 3D image is created according to the topography of the site where the slope protection work 1 is provided.

Specifically, as shown in FIG. 1, photogrammetry using a ground-based or drone / aircraft-mounted laser scanner, drone, etc., using the coordinates of the station Y previously surveyed at the site. Topographical data based on numerical maps and point cloud data is acquired, and then, based on this information, the construction position X and method of the anchor 2 determined by the principle of triangulation from the survey point Y as shown in FIG. A 3D image (virtual space image) in which the surface protection work 1 is displayed is created (see FIG. 2).

Information (information such as coordinates, slightly direction, construction angle, and length) of the anchor 2 to be constructed at the construction position X of each anchor 2 is input to this 3D image.

FIG. 4 shows a case where the 3D image actually created as described above is superimposed on the topography of the site and displayed on the display screen.

A slope protection method using the anchor construction position display device 10 having the above configuration will be described (see FIG. 7).

The construction position X of the anchor 2 is displayed on the anchor construction position display device 10 (mobile terminal).

Specifically, when the anchor construction position display device 10 (camera) is pointed at the slope 3 (construction surface), the anchor created on the display screen 10a according to the topography of the site where the slope protection work 1 is provided. The 3D image in which the construction position X of 2 is displayed and the topography of the site are superimposed and displayed.

Specifically, by touching the display screen 10a to set the two measurement points Y displayed on the screen by the camera function of the anchor construction position display device 10 at the site, the two points of the 3D image can be measured. The points match the local coordinates. By this operation, the construction position X of the anchor 2 and the image of the slope protection work 1 (first beam material 1A and second beam material 1B) are displayed at the corresponding positions (see FIG. 5). It should be noted that the setting of the station can be automatically acquired by using the GPS sensor equipped in the anchor construction position display device 10.

Subsequently, the construction position X of the anchor 2 is determined on the slope 3 of the site based on the information visible on the display screen 10a of the anchor construction position display device 10 (mark the construction position X of the anchor 2 on the construction surface).

Subsequently, the construction positions X of the plurality of anchors 2 determined on the slope 3 of the site are connected with a string or the like, and the slope construction position is reproduced on the slope 3.

Subsequently, the spine and the legal frame formwork are assembled based on the legal frame construction position reproduced on the slope 3 of the site.

Subsequently, mortar is sprayed on a portion of the anchor 2 other than the construction position X, and then the formwork formwork is removed (see FIG. 6A).

Subsequently, an excavation hole 5 is formed at the construction position X of the anchor 2 (see FIG. 6B).

Subsequently, the anchor 2 is constructed in the excavation hole 5 formed at the construction position X of the anchor 2 (see FIG. 6C).

Reference numeral 6 is a protective cap.

Since this embodiment is configured as described above, it is easy for the operator to imagine the completed state of the slope protection work 1 (construction position X of the anchor 2) before the construction, and the 3D image according to the topography of the site. The construction position X of the anchor 2 can be accurately determined based on the information.

Further, in this embodiment, the slope protection work 1 has a configuration in which the first beam member 1A having a length in one direction and the second beam member 1B having a length in the other direction are arranged in an intersecting manner. Since the intersection of the first beam member 1A and the second beam member 1B is the construction position X of the anchor 2, the construction of the grid-like legal frame work can be performed extremely well.

Further, in this embodiment, as described above, a technique (MR: composite reality) of superimposing (fusing) a real space image and a virtual space image (3D image) captured by a camera on the site (real space) of the slope 3 is performed. This is a technology that can be widely applied and applied to various constructions on slopes such as waterway construction and slope protection construction (greening construction) in addition to the slope structure 1 described above.

The present invention is not limited to the present embodiment, and the specific configuration of each constituent requirement can be appropriately designed.
