Abstract

PROBLEM TO BE SOLVED: To reduce cost by using a field source by furnishing a bag of natural vegetable fiber cloth or unwoven fabric, anchor fastenings provided on both ends of the bag and chips of tree-trimmed wood filled in the bag. SOLUTION: One side of a slope frame 1 is made of a square cylindrical or cylindrical bag 2 made of natural vegetable fiber cloth or unwoven fabric, anchor fastenings 3 are provided on both ends of the bag 2, and chips of chipped tree-trimmed wood are filled in the bag 2. Thereafter, the bag 2 is devised to adjust a holding period of the slope frame until it is biodegraded and to be dissolved around the time when vegetation is rooted and a base is stabilized by selecting processing methods of material and antimicrobial processing, insect- proofing, etc. Thereafter, after the chips are filled in the bag 2, one side of the slope frame 1 is combined rectangular, the fastenings 3 are respectively accumulated, an anchor 4 is inserted into a hole 3a for connection and it is fixed on a face of slope of a banking. Consequently, it is possible to reduce cost by using the tree-trimmed wood chips.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the technical field of a legal framework for preventing the collapse of cut and embankment slopes and a method of constructing the same in land construction works such as roads, railways and residential lands.

[0002]

2. Description of the Related Art Conventionally, in a construction work, concrete, net, and plastic law frames have been constructed in order to prevent collapse of a slope. By dividing the slope into fine grids, the lawn frame serves to prevent the vegetation base from collapsing significantly, and becomes unnecessary once the vegetation has taken root and the base has stabilized.

[0003]

However, concrete frames are relatively inexpensive, but they are heavy and therefore difficult to construct, while mesh and plastic frames are easy to construct, but costly. It has the problem of being expensive. Furthermore, with the recent rise in environmental awareness, concrete, plastic, and the like have become unsuitable for landscapes and ecosystems.

On the other hand, at the construction site, open burning is legally prohibited, and it is currently difficult to treat the cut down trees. However, composting is not used much because it is time- and space-constrained and time-consuming, and the required amount of mulching and sidewalk pavement is small, and it is often disposed of as industrial waste. Many. In addition, there is a construction method that uses old-fashioned tree branches (soda) and stakes to protect the slope, but this method is labor-intensive and has not been implemented much because of the shortage of engineers.

The present invention solves the above-mentioned conventional problems and problems. By utilizing local resources, costs such as material costs and industrial waste disposal costs can be reduced. The aim is to provide eco-friendly legal frameworks.

[0006]

For this purpose, the method according to claim 1 of the present invention comprises a bag 2 made of a natural plant fiber cloth or a non-woven fabric, and anchors 3 provided at both ends of the bag.
A method for constructing a legal framework according to claim 2, wherein the method comprises the steps of: combining the legal framework according to claim 1 with a rectangular shape; The anchor frame 4 is fixed to the slope by inserting the anchor 4 into the slope, and the law frame according to claim 3 comprises two bags 2 made of a natural plant fiber cloth or a non-woven fabric, and one end of the two bags. A connection member (5) to be connected, an anchor (3) provided at the other end of the two bags, and a tip of a felling tree filled in the bags (5).
The method for constructing a legal framework according to the present invention is a method of combining the legal framework according to claim 3 in a rectangular shape, and connecting the connecting member 5 to the soil.
The anchor is inserted into the anchor fitting 3 and fixed to the slope.

[0007] In the method according to the fifth aspect, the period until biodegradation is adjusted by selecting the material of the bag and the treatment method such as antibacterial treatment and insect repellent treatment according to the first or third aspect. It is characterized by doing. Note that the numbers added to the above configuration are compared with the drawings for easy understanding of the present invention, and the present invention is not limited thereto.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows one embodiment of the present invention, and FIG. 1 (A) is a perspective view showing one side of a legal frame.
(B) is a perspective view showing an example of construction of a legal frame.

In FIG. 1 (A), one side of a legal frame 1 is a square tubular or cylindrical natural plant fiber cloth or nonwoven cloth bag 2.
(Length about 1m, cross section about 10 × 10cm)
Both ends of the bag 2 are provided with anchors 3.
The bag 2 made of a cloth or a non-woven fabric made of a natural plant fiber can be transported in a foldable and compact form. It should be noted that a connection hole 3 a is formed in the anchor 3. In addition, a bag 2 made of a natural plant fiber cloth or a nonwoven fabric is
By selecting the material and treatment method such as antibacterial treatment and insect repellent treatment, the retention period of the legal framework until biodegradation can be adjusted, so that the vegetation can be decomposed when the rooted base is stable I have. The bag 2 made of natural plant fiber cloth or non-woven fabric is filled with a chip obtained by cutting a cut tree (about 3 cm or less in maximum side length). In addition, a core material made of a reinforcing rod, a branch, or the like may be placed in the bag 2 made of a natural vegetable fiber cloth or a nonwoven fabric.

The method of constructing a legal frame according to the present invention will be described. After filling chips obtained by cutting a cut tree into a bag 2 of a cloth or a non-woven fabric made of natural plant fiber, one side of the legal frame 1 is placed in FIG. As shown in (B), the rectangular shape is combined, the anchors 3 at both ends of the legal frame 1 are overlapped with each other, and the anchor 4 is inserted into the connecting hole 3a to be fixed to the cut or embankment slope to complete it. .

FIG. 2 shows another embodiment of the present invention. FIG. 2 (A) is a perspective view showing two sides of a legal frame, and FIG. 2 (B) is a perspective view showing an example of construction of the legal frame. . The present embodiment includes two bags 2 made of a cloth or a non-woven fabric of natural plant fibers, a connecting member 5 for connecting one end of the two bags, and an anchor 3 provided at the other end of the two bags; The connection member 5 is hooked on the anchor 4 already inserted, and the anchor 4 is inserted into the anchor fastener 3 so as to be fixed to the slope so that the work can be performed. ing. Therefore, the construction becomes easier.

[0012]

As is apparent from the above description, according to the present invention, anyone who has cut down a tree cut at a construction site can be easily constructed by using chips. Therefore, by utilizing local resources, costs such as material costs and industrial waste disposal costs can be reduced, and a legal framework that matches the landscape and is ecologically friendly can be obtained. Cloth or non-woven bags and chips are corroded and returned to soil when the vegetation is rooted and the foundation is stable, making it an environmentally friendly legal framework and using organic fertilizer with chip corrosion (composting). be able to.
