Description

Description: TECHNICAL FIELD The present invention relates to a sloping ground structure constructed on a sloping land with the topography left as much as possible.

[Prior art]

On a sloping land, it is necessary to carry out large-scale construction work such as cutting, embankment and leveling of slopes according to the plan of the building to be built on it, but the construction work on a sloping land will only cost more than flat land. In addition, landslides and ground collapse may occur due to changes in the terrain characteristics.

There is also the problem of natural destruction.

Further, the shape of the structure is often greatly influenced by the terrain on the sloping land, which makes it difficult to design.

The present invention has been proposed in order to eliminate the above-mentioned conventional problems, and when constructing a building on a sloping land, it is possible to reduce the construction work as much as possible, and to keep the natural environment as much as possible. It is an object of the present invention to provide a sloping ground structure capable of constructing a ground structure while leaving it as it is, and further significantly increasing the degree of freedom of planning in constructing the ground structure.

[Means for Solving the Problems]

The present invention relates to a sloping ground structure capable of constructing a ground structure on a sloping land while keeping its topography and natural environment as much as possible. The present invention relates to a sloping ground, and stairs along the inclination direction of the sloping ground. -Shaped underground beams are installed along the width direction of the sloping ground at regular intervals, or in the sloping ground, a continuous underground wall that is continuous in the sloping direction of the sloping ground and has an upper end that is stepped Achieving the above-mentioned object by constructing the artificial ground between the horizontal portions of the upper end of the underground continuous wall and the retaining wall between the vertical portions, respectively, at a constant interval in the width direction of the sloping ground Is.

〔Example〕

 Hereinafter, the present invention will be described with reference to an illustrated embodiment.

On the sloping ground 1, a plurality of underground beams 2 are continuously formed in stages along the inclination direction of the sloping ground 1, and the sloping ground 1
Are arranged at regular intervals in the width direction.

The underground beam 2 is made of steel, reinforced concrete or steel reinforced concrete.

As a method of constructing the underground beam 2, there are a case of complete on-site construction and a prefabricated construction method in which a plurality of parts are factory-produced in advance and then assembled on site.

In addition, the structure type and the size of the cross section of the underground beam 2 are the sloped ground 1
It is decided as appropriate according to the geology of the above and the type and scale of the above-ground structure constructed on it.

An artificial ground 3 is provided between the horizontal portions 2a, 2a of the underground beams 2, 2.
However, the retaining wall 4 is integrally formed with the horizontal portion 2a and the vertical portion 2b between the vertical portions 2b and 2b.

The artificial ground 3 and the retaining wall 4 are made of reinforced concrete or steel-framed reinforced concrete, and the cross section thereof is determined by the type and scale of the above-ground structure like the underground beam 2.

As a construction method of the artificial ground 3 and the retaining wall 4, there are a case where the construction is completed on-site like the case of the underground beam 2 and a prefabricated construction method in which a plurality of parts are factory-produced in advance and assembled on site.

Then, the initially planned ground structure 5 is constructed on the artificial ground 3.

In addition, the planting 6 on the sloping ground 1 without providing the artificial ground 3
May be left as is, leaving as much of the natural landscape as possible.

FIG. 2 shows a second embodiment of the present invention, in which the underground beam 2 is formed in a substantially linear shape along the inclination direction of the sloping ground 1, and the upper end of the underground beam 2 is made into a stepped shape. , The ground beam 2 and a plurality of earth anchors 7, ...
It is firmly anchored to, and the other structure is almost the same as that of the first embodiment.

FIG. 3 shows a third embodiment of the present invention. Instead of constructing the subterranean beam 2 on the sloping ground 1, a continuous underground wall 8 which is continuous in the sloping direction of the sloping ground 1 is formed. The upper end of the underground continuous wall 8 is formed stepwise, and the artificial ground 3 is provided between the horizontal portions 8a of the underground continuous wall 8 and the vertical portion 8a.
The retaining wall 4 is formed between b and 8b, and other configurations are substantially the same as those of the embodiment shown in FIGS. 1 and 2.

The underground continuous wall 8 is constructed by continuously driving a reinforced concrete pile, a steel frame reinforced concrete pile, or a PC pile in the sloping ground 1, or constructing a cast-in-place concrete pile.

〔The invention's effect〕

Since the present invention is configured as described above, it has the following effects.

Regardless of the slope and position of the sloping ground, you can build an artificial ground on the sloping ground while leaving the natural environment as much as possible,
The structural work can be simplified, the construction cost can be reduced, and the degree of freedom of the planning in constructing the above-ground structure can be significantly increased.
