Description

[Detailed description of the invention] [Industrial field of application] This invention relates to a slope protection structure that can be covered with soil to allow vegetation to grow.

[Prior art]

There is a slope protection structure that prevents the slope from collapsing, which is constructed by standing two weir plates parallel to each other on a slope and pouring cement-based hardening material between the weir plates.

[Problems to be solved by this idea]

In such slope protection structures, it is impossible for vegetation to grow on the hardened material, and the structure is exposed on the slope surface, making the entire slope look bad.

This invention was made in order to solve the above-mentioned problems, and the purpose is to provide a slope protection structure that allows vegetation and improves the scenery of the entire slope.

[Means to solve the problem]

A slope protection structure is constructed by standing two weir plates parallel to each other on a slope and pouring cement-based hardened material between the weir plates.

The weir board uses a porous weir board,
Porosity means that the weir plate has a plurality of holes, allowing air in the hardening material to escape. Materials for this porous weir plate include expanded metal, punched metal, crimp wire mesh,
Metal lath etc. can be used.

Cement-based hardening agents include cement milk,
Mortar, concrete, fiber reinforced concrete, etc. can be used.

In this idea, hardened cement material is cast up to the midpoint in the height direction of the left and right weir plates. It is preferable to keep the shaku ruler fixed. The ruler is used as a guide for the top of the cement-based hardened material, and is fixed continuously in the length direction at the vertical middle part of the weir plate. The materials of the ruler include metal, ceramic,
Various materials such as plastic can be used. The cement-based hardening material will be placed along this ruler up to the middle of the weir plate in the height direction.

A weir plate protrudes from this cement-based hardened material,
The protruding parts of this weir board will be covered with soil to make it possible for vegetation to grow.

It is also preferable to fix a long ruler to the upper end of the weir plate on the opposite side of the surface facing the other weir plate. A ruler is fixed continuously along the length of the weir board, and is used as a guide to the top of the soil.

When one weir plate is located at a lower position than the other weir plate with respect to the slope, the height of the weir plate on the lower side of the slope can be made higher than the other weir plate. The cement-based hardening material is placed in line with the low height of the weir board,
The soil will be added along the part of the lower weir board that protrudes from the hardened material.

[Effect]

Since the soil is placed along the weir plates that protrude beyond the cement-based hardening material, the soil does not fall from the top of the structure.
The added soil allows for vegetation to grow on the structure.

The top edge of the cement hardened material can be accurately leveled using a ruler fixed to the middle part of the weir plate in the height direction. A ruler fixed at the top serves as a guide to the top of the clay.

〔Example〕

Hereinafter, this invention will be explained in detail based on an embodiment shown in the drawings.

<Example 1> What is shown in Figures 1 and 2 is a slope protection structure constructed in a lattice pattern on a slope, and the heights of the two left and right weir plates 1, 1 are the same. This is the case. Expanded metal is used as the weir plates 1,1.

Rulers 2, 2 are fixed to the upper and lower middle portions of the weir plates 1, 1 on surfaces facing each other, respectively. Also, at the upper end, rulers 3, 3 are fixed on opposite sides of the surfaces facing each other. The rulers 2 and 3 are made of stainless steel.

The distance between the two weir plates 1, 1 is maintained by a separator, and a plurality of reinforcing bars 4 are arranged along the length direction.

Concrete 5, which is a cement-based hardening material, is placed between the weir plates 1, 1 along the upper ends of the rulers 2, 2. A portion of the weir plates 1, 1 protrudes beyond the concrete 5, but it is also possible to cover this portion with mortar or concrete.

Replacement soil 6 is placed between the weir plates 1 and 1 protruding from the concrete 5. The soil can be leveled along rulers 3 and 3.

All you have to do is grow vegetation on this soil 6.

<Example 2> FIG. 3 shows a case where, of the left and right weir plates 1, 1, the weir plate 1 on the downstream side of the slope is made higher than the other. The concrete 5 is poured to match the height of the weir plate 1 on the upper side of the slope. A part of the weir plate 1 on the lower side of the slope protrudes beyond the concrete 5,
All you have to do is to lay down soil 6 along this weir board 1.

The portion of the weir plate 1 that protrudes from the concrete 5 may be simply buried in the soil 6 without covering it with mortar or the like.

[Effect of idea]

This idea has the above-mentioned configuration, and because the soil is added to the structure, this soil allows for vegetation to form, creating a slope with a good overall landscape without exposing too much of the structure. can.

By fixing a ruler to the upper and lower midpoints of the weir board, this ruler can serve as a guide for pouring the cement-based hardening material, allowing the precise amount of hardening material to be poured and achieving the strength as designed. can.

A ruler installed at the top of the weir board allows the top of the soil to be evenly aligned, resulting in a structure with a good landscape.
