Description

[Detailed description of the invention] The present invention relates to a slope protection method.

Although there are many types of slope protection methods for stabilizing slopes, the present invention aims to provide the following methods.

<1> A slope protection method with excellent stability after installation and high interconnection strength.

<2> A slope protection method that is convenient for transportation and labor-saving in assembly work.

<3> A slope protection method that is suitable for uneven slopes and is easy to install.

<4> A slope protection method that has excellent drainage and prevents slope collapse due to water.

<5> A slope protection method that allows for further beautification by burying protective materials underground.

<6> A slope protection method that easily traps grass and other grass roots and is suitable for full-scale greening.

<7> A slope protection method that improves the stability of the soil over conventional methods.

Next, an example will be described.

In order to achieve the above object, the present invention uses a triangular frame 1 formed by forming a perforated band into a triangular shape, and an anchor 2 for connecting and fixing this triangular frame 1.

<A> Triangular frame Triangular frame 1 For example, as shown in FIG. 1, the triangular frame 1 is constructed of a belt-shaped wire mesh made up of intersecting vertical and horizontal stripes.

The triangular frame 1 is formed by bending this wire mesh into an equilateral triangle or an isosceles triangle.

The corner portion 11 of the triangular frame 1 is formed into a triangular shape.
When arranging the triangular frame 1, which will be described later, only horizontal stripes are arranged without providing vertical stripes because they are connected to each other at the corners.

As a result, slits 12 are formed in each corner 11, which are parallel to each other in the longitudinal direction of each side of the frame.

<B> Other Embodiments The case where a wire mesh is used as the perforated band has been described above, but it can also be used if a perforated steel plate, expanded metal, perforated plastic plate, etc. are formed into a triangular shape.

In that case, a plurality of slits 12 are opened in the corners 11 of the triangular frame 1 in parallel in the longitudinal direction of each side of the frame. (Figure 3) Next, the construction method will be explained.

<1> Arrangement of triangular frames A large number of triangular frames 1 having the structure described above are arranged on a slope. At this time, the slits 12 of each corner 11 of the three triangular frames 1 are intersected at one location and combined.

As a result, three corners 11 are intertwined and formed.
A shared space 4 is formed (Figure 2).If the triangular frame 1 is placed with one side facing perpendicular to the slope direction, this one side will support the earth and sand and improve the stability of the slope. can be improved.

The purpose of this arrangement of the triangular frames 1 is to allow each triangular frame 1 to function in a continuous manner.

Further, a triangular frame 1 having an isosceles triangular shape with the lengths of its two sides adjusted depending on various conditions such as the soil quality and slope of the slope to be protected may be used.

<2> Fixing An anchor 2 is inserted into the space 4 where each corner 11 of the triangular frame 1 intersects and driven into the slope.

The anchor 2 is a single steel rod, and the head may be folded back into a U-shape.

As a result, the triangular frames 1 are not independent, but are interconnected, so even if a part of the slope collapses, the triangular frames 1 will interfere with each other and prevent the collapse. can.

<3> Add soil and vegetation Add soil to the top of triangular frame 1 to the extent that it covers the frame and grow vegetation.

Since the triangular frame 1 is constructed from a perforated strip such as a wire mesh, it can be easily buried in the soil and has excellent drainage properties, allowing rainwater that has seeped into the soil to pass through the holes in the triangular frame 1. Therefore, water retention, which can cause collapse, is less likely to occur.

Since the triangular frame 1 can be buried completely in the soil, the entire slope can be greened.

In addition, the roots of the growing plants can easily become entangled with the triangular frame 1, making greening easy and reinforcing the frame material itself.

Since the present invention has the above configuration, the following effects can be obtained.

<A> The triangle is the most stable shape, and if you compare it with the conventional diamond-shaped (Fig. 5) and box-shaped (Fig. 6) frames, you will find that it has the greatest strength and is extremely stable.

<B> Since each vertex of the triangular frame is connected to the vertex of a separate triangular frame, the mutual connections are extremely strong.

<C> Each triangular frame can be grounded separately according to the unevenness of the ground. (Fig. 7) Comparing this with the conventional legal framework (Fig. 8), it is clear that the conventional legal framework a is made of steel or plastic, so it is a rigid body and cannot be brought into close contact with the ground G. It was difficult.

Therefore, the occurrence of an accident in which the soil flows out from between the legal framework a and the ground G cannot be avoided.

<D> Because the triangular frame has excellent drainage,
Prevents slope collapse due to water and improves slope stability.

<E> Since the triangular frame itself will be buried underground, further beautification will be achieved.

<F> It is easy to grow grass and other plants, and the entire area can be bordered.
