TECHNICAL FIELD OF THE INVENTION The present invention relates to a method for constructing flat land on a gently sloping land, in which the angle of inclination of a steep slope adjacent to the flat land is sufficiently increased to make effective use of the land.

0002

TECHNICAL BACKGROUND OF THE INVENTION For example, when constructing the teeing grounds and fairways of a golf course, flat areas are often formed on gently sloping land. In such cases, embankments are placed on gently sloping land to create flat land;
In this case, a steep slope that has a steep angle with respect to a gentle slope is inevitably formed adjacent to the flat land.

[0003] When this steep slope is formed of embankment, it is necessary to take care to prevent the slope from collapsing, so the actual situation is that the slope of this steep slope is relatively small. Generally, this slope is at most 1
:1.5.

[0004] Here, 1:1.5 represents the inclination angle of the slope. That is, the former "1" means the vertical height of the slope, and the latter "1.5" means the horizontal distance of the slope at this time, and the latter number can be changed. represents the inclination angle. That is, the larger the latter number, the smaller the inclination angle, and the smaller the latter number, the larger the inclination angle. Above slope 1:1.5
is approximately 34 degrees when expressed as an inclination angle. Hereinafter, in this specification, this term will be used to express an inclination.

[0005] However, if this slope is small, the area covered by the embankment becomes large, and as a result, there is a problem in that the area that destroys the natural state becomes large. Therefore, there has been a long-awaited desire for a means for increasing the slope of a steep slope while sufficiently protecting the slope so as not to destroy the natural state of the slope.

[0006]

[Object of the invention] The present invention makes it possible to sufficiently protect the slope of a steep slope, increase the slope of the slope, preserve the natural state as much as possible, and improve the landscape by planting plants. The purpose is to provide a method of construction on flat land that is possible.

[0007]

SUMMARY OF THE INVENTION In order to achieve this object, the level ground construction method according to the present invention is a method of constructing a level ground on a gently sloping land, in which a flat area is formed on the upper surface side, and a step-like slope is formed on the slope side. stacking a large number of foam blocks made of synthetic resin on the gentle slope so as to form a section L;
arranging a L-shaped member and arranging plants within the L-shaped member; covering the flat area with soil to form a flat area;
The present invention is characterized by comprising a step of covering the inside of the L-shaped cross-sectional member and the lower part of the plant with soil to form a steep slope.

As described above, in the present invention, instead of the conventional embankment using "soil", the embankment is made of a large number of foam blocks made of synthetic resin, and since the foam blocks are extremely lightweight, The back earth pressure can be ignored, and even if the steep slope is increased in slope, collapse of the steep slope can be prevented, and the slope of the steep slope can be sufficiently protected.

Moreover, in the present invention, members having an L-shaped cross section are arranged at the ends of each step of the step-like slope area, plants are arranged inside this L-shaped member, and the steep slope is formed by covering with soil. There is. Therefore, the concrete and synthetic resin, which have an undeniable inorganic feel, are almost completely covered with plants and soil, creating a slope that is aesthetically pleasing. Further, by providing a drainage hole or the like in the L-shaped member, it is possible to prevent the soil cover from collapsing even when plants take root.

Therefore, according to the present invention, it is possible to increase the slope of a steep slope while sufficiently protecting the slope and preserving the scenery.As a result, the slope of the steep slope can be increased without destroying its natural state. Effective use can be achieved.

DETAILED DESCRIPTION OF THE INVENTION Hereinafter, a construction method for flat land according to an embodiment of the present invention will be explained with reference to the drawings. FIG. 1 is a schematic diagram of a construction site on level ground according to an embodiment of the present invention, FIG. 2 is a sectional view of a main part of the construction site on flat land shown in FIG. 1, and FIG. 3 is a cross-sectional L-shaped member shown in FIG. 2. and an enlarged cross-sectional view of the foam block.

First, to briefly explain this embodiment, as shown in FIG.
The flat land 2 is formed, and the inclination angle θ of the steep slope 3 can be increased while protecting the slope of the steep slope 3. As a result, the land can be used effectively. This flat ground construction method is applied, for example, to the creation of golf course teeing grounds and fairways, but it is of course not limited to this, and can be applied to extremely wide areas such as the construction of passages and roads, embankments on soft ground, etc. Can be applied to a range.

This construction method will be explained in detail with reference to FIGS. 2 and 3. In the first step, first, a gentle slope 1 is created in a predetermined manner, and then foam blocks 10 made of synthetic resin are stacked, a flat area 11 is formed on the upper surface side, and a step is formed on the slope side. A stepped slope area is formed so as to provide 12.

The foam block 10 is formed in the shape of a rectangular parallelepiped, and its material is preferably foamed styrene, but it may also be a block formed from recycled foamed styrene. Magnification is 10-80
20 to 70 times, preferably 20 to 70 times.

In the second step, a member 13 having an L-shaped cross section is placed at the end 12 of each step of the stepped slope area. Note that this L-shaped cross-sectional member 13 is made of reinforced concrete, synthetic resin,
It is made of synthetic resin foam, iron, steel, and ceramic. Next, the plant 4 is placed inside the L-shaped member 13. The plant 4 is preferably a plant, and may also be a flower. Further, as shown in FIG. 3, a protrusion 15 is formed on the base 14 of the L-shaped member 13, and the foam block 1
A concave groove 16 is formed on the upper surface of the 0, into which the protrusion 15 engages. This prevents the L-shaped member 13 from falling from the stepped portion 12, but a locking tool may be used or it may be fixed with a nail or the like. It may be selected appropriately depending on the material of the member 13.

Furthermore, when the L-shaped cross-section member 13 is made of a material that does not allow water to pass through, a plurality of drainage holes 21 are provided at appropriate locations on the L-shaped cross-section member 13, as shown in FIG. It may be provided. This prevents the slope 3 from collapsing due to water splashing and the growth of roots, making it possible to create a strong slope. Furthermore, in order to prevent landslides from the sides of the slope 3 when constructing a narrow flat area such as a golf course teeing ground or landscaping, as shown in FIG. A side wall 18 may also be provided. Furthermore, as shown in FIG. 5, fine through holes 22 of various shapes or vertically extending elongated holes 23 are provided on the wall surface of the L-shaped cross-sectional member 13 for water drainage and root stiffening. Good too.

In the third step, as shown in FIG. 2, the flat area 11 is covered with soil to form a flat area 2, and the inside of the L-shaped member 13 and the lower part of the plants 4 are covered with soil to form a steep slope 3. ing. In addition, at this time, the L-shaped member 13 may be covered with soil so as to cover the entire section, or conversely, the L-shaped member 13 may be exposed, forming a slope in stages, such as a flower bed. You can create a feeling.

In this embodiment, instead of the conventional "soil" embankment, a large number of foam blocks 10 made of synthetic resin are used.
Since this foam block 10 is extremely lightweight, the back earth pressure can be ignored.
Even if the slope of the steep slope 3 is increased, collapse of the steep slope can be prevented and the slope can be sufficiently protected. Conventionally, this inclination is at most 1:1.5 (i.e., approximately 34 degrees at angle θ), whereas in this embodiment, it is 1:0.364 (i.e., approximately 70 degrees at angle θ). be able to. In the case of cut earth, the slope is approximately 1:0.8 to 1:1.6, but in this embodiment, the slope can be made comparable to or greater than this slope.

Moreover, in this embodiment, an L-shaped member 13 in cross section is arranged at each step 12 of the step-like slope area, and plants 4 are arranged inside this L-shaped member 13 and covered with soil to raise the steep slope 3. is formed. Therefore, concrete and synthetic resin, which have an undeniable inorganic feel, are almost completely covered with plants and soil, creating a slope that is aesthetically pleasing, and the roots of the plants 4 also prevent the soil covering from collapsing. It can be prevented.

Therefore, in this embodiment, the slope of the steep slope 3 can be sufficiently protected and the landscape can be maintained, while the slope of the steep slope 3 can be increased, and as a result, the land can be used effectively. In addition, for embankments that use earth and sand, in the case of large-scale construction, large heavy machinery such as bulltozers may be used,
Although skill is required, this method eliminates the need for these skills, shortens the construction period, and simplifies construction.

Furthermore, since the plants 4 are planted on the steep slope 3, the aesthetic appearance of the steep slope 3 can also be improved, and this construction method is particularly suitable for golf courses and the like. Note that the present invention is of course not limited to the embodiments described above, and can be modified in various ways. In particular, this construction method is not only applicable to golf course teeing grounds, but can also be applied to all other gently sloping areas, such as creating passageways and roads, embankments on soft ground, etc. Furthermore, the shape and material of the foam block are not limited to the examples.

[0022]

[Effects of the Invention] As described above, the present invention uses a large number of foam blocks made of synthetic resin instead of the conventional "soil" embankment, which makes it possible to increase the slope of a steep slope. Even if the steep slope surface collapses, the risk of the slope collapsing can be sufficiently reduced, and the slope surface can be sufficiently protected. Moreover, in the present invention, an L-shaped cross-section member is arranged at the end of each step of the stepped slope area, and plants are arranged inside this L-shaped member and covered with soil to form a steep slope. Therefore,
The member having an L-shaped cross section can prevent the soil covering from collapsing, and can also prevent the soil covering from collapsing when plants take root.

Therefore, according to the present invention, it is possible to increase the slope of a steep slope while sufficiently protecting the slope, and as a result, the land can be used effectively and the landscape is not spoiled. In addition, in the case of large-scale construction using earth and sand, large-scale construction requires the use of large heavy machinery such as bulltozers and skill, but according to this method, these are not necessary, the construction period is short, and the construction is simple. .
