Description

The present invention relates to a filling material filling method for a bag for a rooting construction method used in civil engineering work on, for example, a coast, a river, a lake, or a pond.
In particular, the present invention relates to a filling material filling method for a rooting construction bag body in which a bag formwork frame on which a rooting construction bag body is disposed is freely opened.

Conventionally, sacking bags are used for civil engineering work on coasts, rivers, lakes, ponds and the like.
This bag body for a root hardening method is made of, for example, a knitted fabric, a woven fabric, and a net fabric using synthetic fibers, and generally has flexibility.
Therefore, the shape of the bag body for the root hardening method is not fixed, and it is extremely difficult to throw in the filling material with a fine shape such as crushed stone.
Therefore, after fixing the bag body for the construction method to the form body for the bag body having a fixed shape and stably maintaining the shape of the bag body from the outside, the filling material is put into the bag body .

As such a bag formwork, conventionally, for example, the one shown in FIG. 10 has been used (see Non-Patent Document 1).
The bag body form 101 is a rectangular parallelepiped bottomed or bottomless formwork, and is formed as a rigid body as a whole.
If the side wall of the bag mold 101 is preferably inclined outward, the filling material such as crushed stones can be easily introduced from the opening, and after the filling material is filled, The bag body can be easily lifted and removed from the bag body form 101 (note that the side walls are not inclined in the figure).

As the filling material, crushed stone is mainly used. However, since the crushed stone is hard and heavy, a steel plate is mainly selected as the material of the bag mold 101 that can withstand the weight.
For example, in the bag formwork 101 having a volume of about 1 to 2 m ³ , the thickness of the steel plate is about 5 to 8 mm, which is considerably heavy, and the burden of working is large.

Next, a method of filling the filling material into the bag body for the rooting method using the bag form 101 will be described.
First, the bag form 101 is placed at a predetermined position using a truck crane or the like.
The bag body 102 for the construction method is attached to the mold body 101 for the bag body and arranged.
The point to be noted when attaching the bag body 102 for the rooting method to the bag mold 101 is to arrange the bottom part of the bag body 102 for the root fixing method so as to be in contact with the ground below the bag mold 101. preferable.

This is because when a large amount of the bag body 102 for the root-solidification method enters the form-frame for the bag body, when the bag body 102 for the root-solidification method is pulled up after the filling of the filling material 103 is completed (usually, a truck crane) This is because there is a case where the root-setting method bag body 102 (usually net) and the filling material 103 come into contact with each other to damage the root-setting method bag body 102.
In addition, for example, a bottle unit is used as the bag body 102 for the root hardening method, and this is a Russell net using a recycled polyester fiber having excellent strength characteristics, wear resistance, wear resistance, and the like. It is a manufactured bag.
In addition, when attaching the bag body 102 for the root hardening method to the form frame 101 for the bag body, it is confirmed that the bag body 102 for the root hardening method is not damaged. Care should be taken so that the body 102 does not come off the bag form 101.

The filling material 103 is appropriately selected according to various conditions at the site, such as locally generated materials, purchased materials, and concrete lumps (particle size of 50 mm to about a human head).
In order to apply the pressure to the bag body mold body 101, the filling material 103 is used when the root body bag body 102 is later lifted and removed from the bag body frame 101 in order to apply pressure to the bag body mold frame 101. In addition, rubbing occurs between the bag body 102 for the root hardening method and the inner side surface of the mold body 101 for the bag body, and the bag body 102 for the root setting method is easily damaged.
Further, the filling material 103 has a sharp corner such as swarf stone, and when the rooting construction bag body 102 is pulled up and separated from the bag formwork 101, the sharp slab and the bag body are used. There is a case where the bag body 102 for the rooting method that is interposed between the inner side surface of the formwork is cut.
For this reason, it is often performed that a sucking prevention material (ie, a friction preventing material) having a thickness of about 5 to 10 mm is attached to the inner wall surface of the bag mold 101 as a cushion.
When the sucking prevention material is used in this way, when the root-setting method bag body 102 is pulled up and removed from the bag body mold 101, the risk of the root-setting method bag body 102 being damaged or cut can be prevented as much as possible. It is.

Next, as shown in FIG. 11 (A), using an unillustrated backhoe or the like, the padding material 103 such as crushed stone is scooped up and put into a bag for a rooting construction method set in a bag formwork. .
When this operation is repeated a plurality of times, a predetermined amount of filling material 103 is put into the bag body 102 for the rooting method.
When the filling of the filling material 103 is completed, the mouth portion of the bag body 102 for the rooting method is tightened with a mouth-drawing rope.

Next, as shown in FIG. 11 (B), using a truck crane (not shown) or the like, the rooting construction bag body 102 into which the filling material 103 is put is lifted and moved from the bag body mold 101 to another place. Moving.
This completes the filling of the filling material 103 into the bag body 102 for the root hardening method.

“Bottle Unit”, Construction Technology Examination Report, Civil Engineering Research Center, December 2001, p. 85

However, even if the anti-suction material is disposed in the bag formwork 101 as described above, after the filling material is put into the rooting bag 102, the rooting bag 102 is pulled up. A phenomenon occurs in which the bag body 102 for the rooting method is rubbed against the inner wall of the bag form frame due to the force of spreading outward due to the heavy pressure of the filling material 103.
In particular, when the filling material is a quarry stone having a sharp portion, the bag body is pulled up while being pressed between the filling material 103 and the inner wall of the formwork for the bag body. Or may be cut off.
Further, even when a sucking prevention material is used, such a rubbing phenomenon cannot be completely prevented, so that it remains a problem.

The present invention has been made on the basis of such background technology, and has been made to overcome the above-described problems of the background technology.
That is, the present invention provides a method for rubbing a bag body for a rooting construction method against a formwork for the bag body when it is pulled up in a state where the filling material is put into the bag body for a root hardening construction method (when lifting with a crane or the like). An object of the present invention is to provide a filling material filling method for filling a bag for a rooting method that does not cause cutting.

  Thus, as a result of earnest research on the background of such problems, the inventor of the present invention, after throwing the filling material into the bag body for rooting construction method, by quickly opening the bag formwork, The present inventors have found that the rubbing phenomenon between the bag body and the inner wall of the form frame for the bag body is eliminated, and the present invention has been completed based on this finding.

That is, the present invention is (1) a mold installation step of installing a bag mold at a work site;

Moreover, the freedom degree according to it in the opening process of a bag body form arises by making the mold body for bag bodies into a some division | segmentation frame body.

[Embodiment 1]
Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings.
FIG. 1 is a diagram schematically showing a bag formwork (two-divided one-group type) according to an embodiment of the present invention.
As shown in FIG. 1A, the bag mold 1 includes two arc-shaped divided frame bodies 2A and 2B, and a hinge portion 21 is formed at the end of each divided frame body. .
Of course, the structure of the hinge portion 21 is not limited as shown.
Each of the divided frame bodies can be rotated with respect to each other about the hinge portion 21 to form one divided frame body group, and can be opened outward (see FIG. 1B).
Further, the bag frame 1 can be folded by rotating outward or inward about the hinge 21.
Here, as the material of the divided frame bodies 2A and 2B, for example, a metal plate such as an aluminum plate or a steel plate, a synthetic resin plate, a mesh-like sheet body, or a reinforcing body is added to the mesh-like sheet body. Are appropriately used.

Next, a method of actually filling the filling material into the bag body for the rooting method will be described with reference to the flowchart in FIG. 2 and the process diagram shown in principle in FIG.
In this process drawing, the form 1 for a bag body and the bag body 3 for a root hardening method are shown in a schematic plan view.
First, in step S1, the bag form 1 is installed at the work site as shown in FIG. 3A [form installation step].
After being carried to the site, they are coupled with each other so as not to open the free ends by being rotated around the hinge portions 21 of the divided frame bodies.
For example, what is necessary is just to combine the edge parts of each division | segmentation frame body using a binding tool.
In step S2, as shown in FIG. 3 (B), the root hardening method bag body 3 is placed in the bag body mold 1 [bag body placement step].

In step S3, as shown in FIG. 3 (C), the filling material 4 is put into the bag body 3 for the root hardening method disposed in the bag frame 1 [filling method for filling the filling material].
In step S4, as shown in FIG. 3 (D), the mouth portion of the bag 3 for the rooting construction method into which the filling material 4 is put is tightened with a mouth-drawing rope or the like [mouth-squeezing step].
In step S5, as shown in FIG. 3E, the bag mold 1 is opened (remove a binding tool not shown) and separated from the root hardening bag 3 [opening step].
Specifically, the bag frame 1, that is, the divided frame bodies 2 </ b> A and 2 </ b> B, is opened by rotating the divided frame bodies 2 </ b> A and 2 </ b> B about the center of the hinge portion 21 in the arrow direction (outward direction). .

  When the divided frame bodies 2A and 2B are opened as described above, the bag body 3 for the root hardening method can secure a degree of freedom to move in a direction parallel to the ground. When the bag body 3 is lifted, the root-setting method bag body 3 does not rub against the bag-type mold 1 at all, and the root-setting method bag body 3 is not damaged or cut.

Finally, in step S6, as shown in FIG. 3 (F), the root hardening method bag body 3 whose mouth is tightened is lifted by a truck crane (not shown) and moved to another place [ Lifting process].
Note that the opened bag form 1 is re-installed in the original initial state in order to input the filling material into the next new root hardening bag 3.
When the filling material filling operation is finally finished, the bag form 1 is folded to reduce the volume.

The above has been described with reference to the example of the bag mold 1 provided with two arc-shaped divided frames and the hinges 21 are formed at the ends of the divided frames. To state.
Here again, the process diagrams (FIGS. 4 to 8) show the form frame 1 for a bag body and the bag body 3 for a root hardening method in a schematic plan view.

[Embodiment 2]
FIG. 4 shows a process diagram using a bag formwork (two-split independent type) according to another embodiment of the present invention.
As shown in FIG. 4A, the bag mold 1 includes two arc-shaped divided frame bodies 2A and 2B, and the divided frame bodies are independent of each other.
In the mold installation step, the free ends of the divided frame bodies are joined using a binding tool (the same applies to the following embodiments).
An opening process is performed by separating each division | segmentation frame body 2A, 2B in the direction which opposes from the bag body 3 for a construction method.
Since each division | segmentation frame 2A, 2B can be moved independently independently, it can be separated freely.
Since the root hardening method bag body 3 does not come into contact with the bag body mold 1, damage and cutting due to rubbing of the root hardening method bag body 3 can be reliably avoided.
This bag form has the merit that it can be stored as a small volume by superimposing the divided frame bodies 2A and 2B.

[Embodiment 3]
FIG. 5 shows a process diagram using a bag formwork (3-split independent type) according to another embodiment of the present invention.
As shown in FIG. 5, the bag mold 1 includes three arc-shaped divided frame bodies 2 </ b> A, 2 </ b> B, and 2 </ b> C, and the divided frame bodies are independent of each other.
The opening process is performed by separating each of the divided frame bodies 2A, 2B, 2C from the bag body 3 for the construction method, for example, in directions different from each other by 120 °.
Since the divided frame bodies 2A, 2B, and 2C are smaller than those of the divided frame bodies divided into two as shown in the above-described second embodiment, the divided frame bodies are lighter and easier to separate.
This form for a bag can also be stored as a smaller volume than the case of the above-mentioned two-minute divided frame by overlapping the divided frames.

[Embodiment 4]
FIG. 6: shows the process drawing using the form for bag bodies (3 division 1 group type | mold) which concerns on another one Embodiment of this invention.
As shown in FIG. 6, the bag mold 1 includes three arc-shaped divided frame bodies 2 </ b> A, 2 </ b> B, and 2 </ b> C, and two of the divided frame bodies are mutually connected via a hinge portion 21. Can be freely rotated to form a group.
Since the remaining one divided frame 2C is independent, it can move freely.

[Embodiment 5]
FIG. 7 is a process diagram using a bag formwork (three-part one-group type) according to another embodiment of the present invention.
The bag mold 1 includes three arc-shaped divided frame bodies 2A, 2B, and 2C, as in the fourth embodiment, and among them, the three divided frame bodies are in turn two of each other. The two hinge portions 21 are connected to each other so as to freely rotate to form a group.
Therefore, in the opening process, it is possible to open to the starting point of the divided frame body 2A, or to open the divided frame body 2A and the divided frame body 2C on both sides starting from the divided frame body 2B. high.
When connected through the hinge portion 21 as described above, the bag body mold 1 can be easily returned to the original setting position when the bag body 3 for the root-sealing method is placed next. Efficiency is improved.

[Embodiment 6]
FIG. 8 shows a process diagram using a bag formwork (four-divided two-group type) according to another embodiment of the present invention.
The bag body mold 1 includes four arc-shaped divided frame bodies 2A, 2B, 2C, and 2D. Of these, the two divided frame bodies are rotatable with respect to each other via a hinge portion 21. This is a case where there are two divided frame groups that are hinged.
In the opening step, the divided frame bodies 2A and 2B and the divided frame bodies 2C and 2D connected to each hinge are rotated, and at the same time, the divided frame body groups are separated from each other and opened.
Moreover, since there are four division frames, it can be folded compactly, which is convenient for storage and transportation.

As described above, in the present invention, when the divided frame body 2 is in the open state, the bag body 3 for solidifying construction method secures a degree of freedom to move in a direction parallel to the ground, and the following steps: That is, when the root-setting method bag body 3 is lifted, the root-setting method bag body 3 is not rubbed against the bag body mold 1 at all, and the root-setting method bag body 3 is not damaged or cut.
The above describes the filling method of filling material using the bag form 1 in principle.

Next, a filling material charging method using a specific bag form 1 will be described.
FIG. 9 is a diagram illustrating a method of actually filling the filling material into the bag for the construction method according to the process, and is the case of the second embodiment.
The bag mold 1 used here is composed of two arc-shaped divided frame bodies 2A and 2B as shown in the second embodiment, and the divided frame bodies 2A and 2B are independent of each other.
Each of the divided frame bodies 2A and 2B is formed of a mesh-like bent sheet [specifically, Adem (trademark)], but is also provided with a reinforcing material (frame frame) for reinforcing it.

[Step S1]
First, in the mold installation step, the bag mold 1 is carried to the site and installed at the optimum position on the work site [see FIG. 9 (A)].
At the time of installation, the divided frame bodies 2A and 2B are arranged in a ring shape and their ends are connected by a binding tool K such as a rope.

[Step S2]
In the bag body arranging step, the root hardening method bag body 3 is placed in the bag body frame 1 (see FIG. 9B).
Specifically, as shown in the figure, the bag body 3 for root hardening method is folded back so as to straddle the mounting outer surface along the inner surface of the bag body frame 1.

[Step S3]
In the filling material filling method, the filling material 4 is charged into the bag 3 for the rooting method placed in the bag frame 1 (see FIG. 9C).
Since the mouth of the bag body 3 for the root hardening method is greatly opened along the form frame 1 for the bag body, the filling material 4 can be put in very easily.

[Step S4]
In the mouth squeezing step, after the filling of the filling material 4 is completed, the mouth portion of the bag 3 for the rooting construction method into which the filling material 4 has been placed is tightened with a mouth drawing rope L or the like [FIG. )reference〕.
In this case, a fastener may be used instead of the mouth-drawing rope.

[Step S5]
In the opening step, the bag form 1 is opened and separated from the root hardening bag 3 (see FIG. 9E).
In this separation work, a binding tool such as a rope that binds the divided frame bodies 2A and 2B to each other is released, and the divided frame bodies 2A and 2B are respectively set in directions opposite to each other from the bag body 3 for the construction method (referred to in the figure). Can be accomplished easily by moving outward).
Here, since the bag form 1 is formed of a mesh-like bent sheet [for example, Adem (trademark)] having a reinforcing material, it is relatively light, so that the divided frames 2A and 2B are manually formed by an operator. Can be lifted and released quickly.
Since the root hardening method bag body 3 never comes into contact with the bag body mold 1, the root hardening method bag body 3 is not damaged or cut by rubbing.

[Step S6]
Lastly, in the lifting step, the root hardening method bag body 3 with the mouth portion tightened is lifted by a truck crane or the like (not shown) and moved to another place (see FIG. 9F).
For lifting, lifting is performed using a lifting rope or hook separately attached to the mouth of the bag 3 for the root hardening method.
This completes the filling of the filling material 4 into the bag body 3 for the root hardening method.

Although the embodiment has been described above, the present invention is not limited to this embodiment, and various modifications are possible as long as the purpose is met.
For example, the number of divisions of the bag form used for the filling material charging method can be five or more, and the method of hinge connection can be selected as appropriate.
The formwork for the bag body can of course have a structure that allows the inside to be seen so that the filling degree of the filling material in the bag body for the rooting method can be visually confirmed, and the weight is lighter than the selected material load. It is also possible to do.
Moreover, various choices are also possible for the pivot attachment structure for hinge connection.
In addition, the ends are joined together to form the bag formwork into a ring shape, and as a coupling tool, a coupling means using an insertion rod can be naturally adopted in addition to a rope, a string, a wire, etc. is there.

  The present invention relates to a filling material filling method for a bag body for a root hardening method, but as long as the principle can be used, it is naturally applied to a bag body filled with a filling material such as stone for other civil engineering. Is possible.
