Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a method for forming a sandbag for supporting earth pressure such as embankment.

<Background Art> To support the earth pressure of an embankment, a face, or the like, a sandbag filled with a filler such as sand in a bag body is used.

<Problems to be Solved by the Present Invention> A conventional sandbag is obtained by filling a bag body with a filler such as sand manually.

Therefore, it took a lot of time and labor to form the sandbag.

Also, if the sandbag is damaged, the filler such as the filled sand leaks out, and there is a possibility that the function as the sandbag is lost at all.

<Object of the present invention> The present invention has been made to solve the above problems, and provides a method for forming a sandbag capable of easily and quickly forming a sandbag and imparting shape stability due to breakage. The purpose is to:

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

<A> Formation of Bag Body The bag body 1 is formed of a flexible sheet having at least air permeability, for example, cloth.

The shape and size of the bag 1 are selected according to the use of the sandbag, but the present embodiment is for forming a long pillow-shaped sandbag.

The bag 1 is closed, and the inside is divided into a plurality of rooms.

In order to divide the inside of the bag 1 into a plurality of rooms, the inside of the bag 1 may be partitioned by a sheet having the same air permeability as the sheet forming the bag 1.

For example, as shown in FIG. 1, according to a method in which a longitudinal end portion of a sheet-shaped body is folded inward and the edge portion is fixed by a clasp 11, the sheet can be easily divided.

Each of the divided chambers of the bag 1 is provided with one or a plurality of inlets 12 for a filler such as sand.

The inlet 12 has a pocket shape, and the hose 2 for injecting sand or the like can be inserted therein.

When the hose 2 is withdrawn with sand or the like, the inlet 12 is naturally closed.

<B> Pressure Feeding of Filler Sand 3 or the like is used as a filler to be filled in the bag body 1.

For example, as shown in FIG. 1, the filling material pumping apparatus may be one in which a compressor 22 is connected to a pumping machine 21 having a filling hose 2.

First, the tip of the hose 2 is inserted into the inlet 12 of the bag 1.

Next, the pumping machine 21 and the compressor 22 are operated, and the sand 3 is put into the pumping machine 21 by a belt conveyor or the like, and is fed into the hose 2 by pressure.

Then, the sand 3 is vigorously spouted into the bag 1 from the end of the hose 2, and the sand 3 can be immediately filled into the bag 1 by the pumping force of the machine.

At this time, since the bag 1 has air permeability, the air escapes to the outside of the bag 1 and only the sand 3 is filled in the bag 1.

After filling all the rooms in the bag 1 with the sand 3,
Then, the compressor 22 is stopped, and the hose 2 is pulled out of the bag 1.

At this time, since the inlet 12 is configured to close naturally when the hose 2 is pulled out, the work of closing the inlet 12 can be omitted.

As another method of pressure-feeding the filler, a method of pushing the filler into the bag 1 using a piston or the like is also conceivable.

 Thus, the formation of the sandbag is completed.

<Effects of the Present Invention> Since the present invention has been described above, the following effects can be expected.

<A> In the conventional sandbag, since a bag is filled with a filler such as sand by hand, a great deal of time and labor is required for forming the sandbag.

On the other hand, in the present invention, a filling material such as sand is efficiently filled into a bag having air permeability by a pumping force of a machine.

Therefore, the sandbag can be formed very quickly and easily as compared with the case of the conventional manual operation.

<B> In the present invention, a filler such as sand can be efficiently filled by the pumping force of the machine, so that a large-capacity sandbag can be formed in a short time.

<C> The sandbag of the present invention has a structure in which a plurality of rooms communicating with each other over the entire length in the longitudinal direction are formed and divided.

 Therefore, stability when the sandbag is installed is improved.

Also, in the event that the sandbag is damaged, the filler leaks only into the room at the damaged position, so that the longitudinal shape of the sandbag itself remains stable.

<D> The filler inlet provided in the sandbag of the present invention is configured to close naturally when the filler hose is pulled out.

 Therefore, the work of closing the injection port can be omitted.
