Description

TECHNICAL FIELD 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 flood damage caused by a natural disaster such as a typhoon or an earthquake.

In recent years, large-scale typhoons often cause rivers to overflow, causing flooding to the floors of houses and the like.
Furthermore, flood damage occurs in which sewage flows backward due to swollen river water, and sewage spouts out from manholes and the like, flooding the inside of buildings.

In order to prevent flood damage to such houses in advance,
(1) Build a building after embanking the site and raising the ground of the residential land.
(2) Concrete is poured around the building to build a retaining wall (a wall formed by pouring concrete into a formwork or a wall-like structure using concrete blocks), and at the entrance (gate) of the site. Install sandbags, waterproof sheets, waterproofing devices, etc. in preparation for floods and other water damage.
Such countermeasures were necessary.

In particular, in the case of wooden houses, since water seeps in through gaps between the foundations and sills, it was necessary to enclose the entire perimeter of the building with structures such as retaining walls to stop water in order to prevent water from entering the building.

Since the embankments and retaining walls described above are extremely expensive to introduce, even if they can be introduced in large-scale facilities, it is difficult to popularize them in small-scale facilities and buildings such as small offices, shops, and private residences. It was difficult in terms of introduction cost.

The present invention has been made in view of the above-mentioned problems, and is capable of reducing the introduction cost and reliably preventing the inflow of water such as flood water to prevent the building from being flooded. The task is to provide a levee for

In order to solve such a problem, the invention described in claim 1 provides an embankment for protecting buildings from water damage such as flooding. A cutoff wall with its ends superimposed side by side and an L-shaped reinforcing steel material for vertically fixing the cutoff wall to the building side of the cutoff wall are attached with a plurality of bolts, and the lower part of the square corrugated steel plate is placed underground. It is inserted into the Y-shaped sandwiching metal fitting formed in the foundation formwork for square corrugated steel plate with a substantially concave shape embedded in the surface, and is placed at an angle of about 45 degrees with respect to the ground surface at the upper part and about the upper and lower middle part of the L-shaped reinforcing steel material. Two diagonal reinforcing columns are attached, screw anchor metal fittings are pressed into the ground at the lower ends of the two diagonal reinforcing columns, the upper parts of the screw anchor metal fittings and the lower ends of the diagonal reinforcing columns are fixed, and the two diagonal reinforcing columns are reinforced. A recessed foundation formwork is constructed in the ground at the lower end of the column, and concrete is poured into the square corrugated steel plate foundation formwork and the recessed foundation formwork to fix the cutoff wall.

In addition to the structure described in claim 1, the invention according to claim 2 is characterized in that the rectangular corrugated steel plate is formed so that the depth of the peak height dimension is the same, and the peak dimension and the valley dimension are adjusted from the bottom to the top from the bottom. It is characterized in that it is formed wide in order.

The invention according to claim 3, in addition to the structure according to claim 1 or 2, is characterized in that the foundation formwork for square corrugated steel plates is formed on the ground surface outside the cutoff wall so that the upper end is formed into a generally L shape. Along with burying the outer earth retaining steel plate, a flat inner earth retaining steel plate is buried on the underground surface inside the cutoff wall, and both ends of the outer earth retaining steel plate and the inner earth retaining steel plate are bent at right angles. The square corrugated steel plate is connected in parallel with the inverted concave flat metal fittings, and a Y-shaped sandwiching metal fitting for sandwiching and fixing the lower part of the square corrugated steel plate is attached to the upper surface of the inverted concave flat metal fittings.

In addition to the structure described in claim 1 or 2, the invention according to claim 4 has flat steel plates buried parallel to the ground surface on both sides of the lower ends of the two oblique reinforcing columns. , by pouring concrete into the recessed foundation formwork, the screw anchor hardware and two oblique reinforcing columns are fixed in the ground.

According to the invention of claim 1, in the embankment for protecting buildings from flood damage such as flooding, the embankment is formed by arranging a plurality of thin and wide square corrugated steel plates formed into square corrugations in the horizontal direction and overlapping the ends. A combined cutoff wall and an L-shaped reinforcing steel material for fixing the cutoff wall vertically to the building side of the cutoff wall are attached with a plurality of bolts, and the lower part of the square corrugated steel plate is buried in the underground surface. It is fitted into the Y-shaped sandwiching hardware formed in the base mold for concave square corrugated steel plates, and two oblique reinforcements are provided at an angle of approximately 45 degrees to the ground surface at the upper portion and approximately the upper and lower intermediate portions of the L-shaped reinforcing steel material. Attach the pillars, press the screw anchor hardware into the ground at the lower ends of the two diagonally reinforced columns, fix the top of the screw anchor hardware and the lower ends of the diagonally reinforced columns, and fix the lower ends of the two diagonally reinforced columns. A recessed foundation formwork was constructed in the ground, concrete was poured into the foundation formwork for the square corrugated steel plate and the recessed foundation formwork, and a cutoff wall was fixed. As a result, it became possible to protect buildings from water damage such as floods.

According to the second aspect of the invention, the square corrugated steel sheet is formed so that the depth of the peak height dimension is the same, and the peak dimension and the valley dimension are widened in order from the lower end to the upper end. Using commercially available galvalume steel plates, etc., it has become possible to construct a cutoff wall that secures the strength of the embankment against flooding simply and inexpensively.

According to the third aspect of the invention, the foundation formwork for square corrugated steel plates includes an outer earth retaining steel plate having an approximately L-shaped upper end portion that is embedded in the ground surface outside the cutoff wall. A flat plate-like earth retaining steel plate for the inside is buried in the ground surface inside the water wall, and the earth retaining steel plate for the outside and the earth retaining steel plate for the inside are made parallel with multiple reverse concave flat metal fittings with both ends bent at right angles. , and a Y-shaped clamping metal fitting for clamping and fixing the lower part of the square corrugated steel plate is attached to the upper surface of the inverted concave flat metal fitting, making the cutoff wall independent from the ground surface in a simple and inexpensive manner. It is now possible to prevent water intrusion.

According to the fourth aspect of the invention, the concave foundation formwork is made by embedding flat steel plates in parallel in the ground surface on both sides of the lower ends of the two oblique reinforcing columns, and pouring concrete into the concave foundation formwork. As a result, it became possible to make the cutoff wall self-supporting by a simple and inexpensive method by fixing the screw anchor hardware and two diagonal reinforcing columns in the ground.
