Description

The present invention relates to a method for constructing a building embankment for preventing flooding of a building or the like in the event of a flood or the like caused by a natural disaster such as a typhoon or an earthquake.

In recent years, large typhoons have caused frequent flooding of rivers and flooding of houses and the like.
In addition, flood damage has also occurred in which sewage flows backward due to the flooded river water, and sewage is ejected from manholes and the like and inundates the inside of the building.

In order to prevent such flood damage to houses in advance,
(1) Build the building after embanking the site and raising the ground of the residential land.
(2) Retaining walls (walls formed by casting concrete into formwork and wall-like structures using concrete blocks) are constructed by placing concrete around the building, and at the entrance (gate) of the site. Install soil coverings, waterproof sheets, water stop devices, etc. in case of floods or other floods.
Such measures were necessary.

In particular, in the case of a wooden house, water infiltrates through the gaps between the foundation and the foundation, so in order to prevent the inundation of the building, it was necessary to enclose the entire circumference of the building with a structure such as a retaining wall to stop the water.

Since the introduction cost of embankments and retaining walls as described above is extremely high, even if they can be introduced in large-scale facilities, it is not possible to spread them in small-scale facilities and buildings such as small offices, stores, or private residences. It was difficult in terms of introduction cost.

The present invention has been made in view of the above-mentioned problems, and the introduction cost can be reduced, and the inflow of water such as a flood can be surely prevented to prevent the inundation of the building or the like. The challenge is to provide a dike.

In order to solve such a problem, the invention according to claim 1 is an embankment for protecting a building from flood damage such as a flood. In order to vertically fix the water stop wall with its ends overlapped side by side, bolt the water stop wall so as to sandwich it between the two sets of triangular support columns formed in a substantially right triangle. After fixing, the lower part of the opposite side of the triangular support pillar is attached to the concave foundation formwork embedded in the underground surface to fix the water blocking wall, concrete is poured into the concave foundation formwork, and the lower part of the water blocking wall and the triangle. It is characterized by fixing the support pillars.

The invention according to claim 2 is characterized in that, in addition to the structure according to claim 1, the triangular support column is a combination of three flat steel plates bent into an L shape in a substantially triangular shape.

The invention according to claim 3 is characterized in that, in addition to the structure according to claim 1, the triangular support column is a combination of three angle steels in a substantially triangular shape.

The invention according to claim 4 is characterized in that, in addition to the structure according to claim 1, the triangular support column is a combination of three pipes whose tips are crushed into a flat plate shape in a substantially triangular shape.

In the invention according to claim 5, in addition to the structure according to any one of claims 1 to 4, the screw anchor hardware is loosened in the ground at the tip of the support column where the hypotenuse and the adjacent side of the triangular support column are joined. It is characterized in that the upper part of the screw anchor hardware and the tip end portion of the support column are fixed by being rotated and press-fitted.

In the invention according to claim 6, in addition to the structure according to any one of claims 1 to 5, the concave foundation formwork is formed of an L-shaped earth retaining flat steel plate in which the left and right formwork are formed into a substantially L shape. At the same time, in order to connect the left and right L-shaped earth retaining flat steel plates in parallel, an inverted T-shaped metal fitting was attached to the left and right wall surfaces, and the rising side of the inverted T-shaped metal fitting and the lower part of the opposite side of the triangular support column were fixed. It is characterized by.

According to the invention of claim 1, in an embankment for protecting a building from flood damage or the like, a plurality of thin and wide angular corrugated steel plates formed into an angular corrugated shape are arranged in a horizontal direction and their ends are overlapped. In order to vertically fix the combined water stop wall and the water stop wall, fix the water stop wall with bolts so as to sandwich the water stop wall between two sets of triangular support columns formed in a substantially right triangle, and fix the triangle. The lower part of the opposite side of the support pillar was attached to a concave foundation mold buried in the underground surface to fix the water stop wall, concrete was poured into the concave foundation mold, and the lower part of the water stop wall and the triangular support pillar were fixed. As a result, it became possible to construct a dike with a simple structure at low cost, and it became possible to protect the building from floods and other flood damage.

According to the invention of claim 2, the triangular support column is formed by processing a commercially available steel material or the like to construct an embankment at low cost by combining three flat plate steel plates bent into an L shape into a substantially triangular shape. It became possible.

According to the invention of claim 3, the triangular support column can be constructed by processing a commercially available steel material or the like at low cost by combining three angle steels in a substantially triangular shape. rice field.

According to the invention of claim 4, the triangular support column is formed by processing a commercially available steel material or the like to construct an embankment at low cost by combining three pipes whose tips are crushed into a flat plate shape in a substantially triangular shape. It became possible to do.

According to the invention of claim 5, the screw anchor metal fitting is slowly rotated and press-fitted into the ground at the tip of the support pillar where the hypotenuse and the adjacent side of the triangular support pillar are joined, and the upper part of the screw anchor metal fitting and the support pillar are press-fitted. By fixing the tip, it became possible to firmly fix the embankment with a simple structure.

According to the invention of claim 6, the concave foundation formwork is formed of an L-shaped earth retaining flat plate steel plate obtained by forming the left and right formwork into an approximately L shape, and the left and right L-shaped earth retaining flat plate steel plates are connected in parallel. Therefore, by attaching inverted T-shaped metal fittings to the left and right wall surfaces and fixing the rising side of the inverted T-shaped metal fittings and the lower part of the opposite side of the triangular support pillar, the embankment can be fixed to the ground with simple earthwork. Is now possible.
