Abstract

PURPOSE:To enable the installation of a large-sized sandbag by reinforcing a side wall of a large-sized bag body formed of materials having flexibility, water permeability and tensile strength with a plurality of circular bodies at specific intervals in a cross sectional direction. CONSTITUTION:Reinforced bars are bent in the shape of a circle to form reinforced rings 10, coupling rings 11 are welded to four places into which the perimeter is divided, and two parallel bearing bars 12 are welded to the ring 10 used in the lowest place. After that, ropes 2 to make the bottom intersect crosswise are connected to the coupling rings 11, and rings 21 are mounted to the upper ends of the ropes 2 to form a reinforced cage 1. Then, after woven cloth having flexibility, water permeability and tensile strength is sewn in a cylindrical shape, the bottom is shut to form a large-sized inside bag 3. In the next site to be used, the cache is enlarged to install the bottom plate 13 on the bearing bar 12, the bag 3 is set in the cage 1 to complete a large-sized sandbag 4, and the edge of the upper end of the bag 3 is cut to fill soil 5 thereinto by means of a machine. The rings 21 are suspended, the sandbag 4 is built in a specific position on the face of slope by using a crane. According to the constitution, the installation of the sandbag 4 can be easily executed.

Description

Detailed Description of the Invention

[0001]

This invention relates to large sandbags.

[0002]

[Prior Art and Problems] Recently, it is difficult to secure workers who engage in simple labor at construction sites. Sandbags are extremely effective materials because they have good stains on site and are inexpensive, but due to lack of manpower, they are becoming increasingly expensive. The inventor is the Japanese Patent Publication No.
In the name of the invention, "Slope Stabilization Method", at least a part of the periphery is made of a rigid material, and a large container made of a material having strength, flexibility and water permeability is filled with soil and then laid on the slope. A slope stabilization method was proposed.

[0003]

The present invention is a large sandbag provided to more effectively realize the above proposal. The purpose of the present invention is to provide a large sandbag that can be installed by using a machine to fill the soil. For that purpose, a plurality of annular bodies made of a rigid material are vertically connected at predetermined intervals with a flexible rope-like material having a large tensile strength to form a reinforcing cage. Then, a large bag body made of a material having flexibility, water permeability and tensile strength is fitted inside.

[0004]

[Operation] Since the large sandbag of the present invention is constructed in this manner, the work such as soil filling and installation can be performed by mechanical force,
Even if a large amount of soil is put in, it can be held in shape by being restrained by the reinforcing ring. Unlike when reinforced with a planar rigid body, it can be stored in a crushed state like a lantern when not in use.

[0005]

Embodiment 1 An embodiment of the present invention will be described in detail below with reference to the drawings. As shown in FIG. 1, a reinforcing bar 10 having a diameter of 50 cm is formed by bending a reinforcing bar having a thickness of 9 mm into a circular shape.
The cut part is welded to form a complete ring. A small connecting ring 11 is welded to a portion where the periphery is divided into four. Two parallel support pieces 12 are welded to the reinforcing ring 10 used at the bottom. Two ropes with high tensile strength and flexibility 2
Using a cross-shaped cross-section on the bottom surface, 16 reinforcing rings of the same size are connected at an interval of 20 cm above and below. The rope 2 is connected at four points that divide the circumference of the reinforcing ring into equal parts. A reinforcing basket 1 having a height of 1 m is formed. In order to fix the reinforcing ring, the rope 2 is fixed through the connecting ring 11 attached around the reinforcing ring. A suspension ring 21 is attached to each upper end of the rope 2. The reinforcing basket 1 formed in this way can be compressed into a crushed shape when the rope 2 is loosened, and can be expanded like a lantern by lifting it with the rope.

As shown in FIG. 2, a flexible, water-permeable, and tensile-strength woven fabric made of polyethylene resin flat yarn is sewn into a tubular shape, and the bottom is closed to form a large tubular shape. The bag 3 is formed. The diameter is 50 cm and the height is 120 cm. Fold it small before use.

As shown in FIG. 3, at the site of use, the reinforcing cage 1 is installed in an enlarged state, and the support bar 1 on the bottom surface is used.
A bottom plate 13 made of expanded metal is placed on top of 2, and a large inner bag 3 is set in a reinforcing basket 1 to complete a large sandbag 4. At the place where it hits the rope 2, the edge of the upper end of the large bag 3 is cut off, and the large bag 3 is wound around the uppermost reinforcing ring 10 and placed with its mouth wide open. Center of bottom,
From the point where the ropes intersect, if you attach another rope above the bottom plate through the bottom plate, it is convenient because there is little deflection on the bottom when lifting. The soil 5 is packed in such a large sandbag 4 using a machine such as a Yumbo. As shown in the figure, using a hoisting jig 23 having hooks 22 attached to the four corners, hoisting the hoisting ring 21 at the ends of the four ropes 2 of the large sandbag 4, and using a machine such as a crane. Lay it in place on the slope.

The material of the reinforcing ring used in the present invention is not particularly limited as long as it has rigidity, but a steel material is generally used in terms of strength / price. In addition to the circular shape shown in the embodiment, a quadrilateral shape is also common.
As the reinforcing ring, a pipe, a corrugated plate, a thick plate or the like can be used in addition to the reinforcing bar / angle member. In the case of semi-permanent use, a galvanized product, a rust preventive coating product, or the like may be used. The rope is not limited to a rope as long as it has a sufficiently high tensile strength to be used for connecting and hoisting a reinforcing ring, and a belt-shaped body made of a woven cloth having a narrow width may be used. Further, the reinforcing ring and the large bag may not necessarily be separate, and when the bag having sufficiently high tensile strength is used, the reinforcing ring may be directly attached to the bag.

[0009]

Since the present invention is constructed as described above, it has the following features. (1) The sandbag is simple, can be dyed in the shape of the site, and is extremely effective as a soil stopper. However, recently there is no manpower to pack sandbags, so there is a drawback that the cost is high. The large sandbags aim to be filled with the soil using a machine and installed using the machine, and the advantage of the sandbag can be left and the labor shortage can be solved. (2) When the flexible bag is filled with soil, it is inevitably in a circular mountain-like state. The invention seeks to limit this shape to the desired one using a reinforcing ring. If the whole is made of a rigid body, the cost is high, it is heavy, and it is difficult to carry. Therefore, by attaching the reinforcing rings substantially horizontally at predetermined intervals, the overall shape can be maintained. (3) Since the reinforcing rings are connected vertically with a flexible rope-like object, it can be crushed and compact when not in use, making storage and transportation easy. is there. (4) When the soil is packed, the weight increases, but when suspended, the rope is tightly tensioned, which has the effect of suppressing the bag from expanding in a round shape. Therefore, if the tensile force is large in the vertical direction, it can be used instead of the rigidity. (5) Various shapes can be obtained by selecting the shape of the reinforcing ring. (6) Since the construction speed of soil filling and installation using mechanical force is fast, it is also very effective for emergency disaster prevention. (7) By connecting the reinforcing rings together, it is easy to make a nodule as a whole, and the slope stabilization effect as a whole is great.
