Description

  The present invention relates to a bag body for a rooting method used in civil engineering work on, for example, a coast, a river, a lake, a pond, and the like. The present invention relates to a form for a bag body and a method for charging a filling material into a bag body for a root hardening method.

Conventionally, sacking bags are used for civil engineering work on coasts, rivers, lakes, ponds and the like.
This bag is made of, for example, a knitted fabric, a woven fabric, a mesh fabric, or the like formed using synthetic fibers, and generally has flexibility.
Therefore, when the shape of the bag body is not fixed and a fine filling material such as crushed stone is introduced, it is difficult to input.
Therefore, after the bag body is attached to a fixed formwork and the shape is stabilized, the filling material is put into the bag body.

Here, conventionally, for example, the mold shown in FIG. 11 has been used (see Non-Patent Document 1).
This formwork is a rectangular parallelepiped container similar to a bathtub, and the bottom is missing.
And the side wall of the formwork is tapered from the bottom side toward the opening side, so that it is easy to throw in filling material such as crushed stone from the opening.
Further, if the shape is tapered, it is easy to pull the bag body away from the mold after the filling material is charged.

As the filling material, crushed stone is mainly used. However, since the crushed stone is hard and heavy, a steel plate material is mainly selected as the material of the mold to withstand it.
For example, those having a 1 m ³ to 2 m ³ approximately volume mold, the thickness of the steel material, becomes about 5 to 8 mm, a fairly gravimetrically heavy.

Next, a method for charging the filling material into the bag body for the rooting method using this mold will be described.
First, the formwork is arranged at a predetermined position by a truck crane or the like.
As shown in FIG. 12 (A), a rooting construction bag is attached to the mold and arranged.
As a point to be noted when attaching the bag body for the root hardening method to the mold frame 101, it is preferable to arrange the bag body so that the bottom of the bag body is in contact with the ground below the mold frame 101.

This is because when the bag body 102 enters a large amount within the formwork, when the bag body is pulled up after the filling of the filling material 103 is completed, the bag body (usually netting) and the filling material 103 are mutually connected. This is because there is a case where the bag body 102 is damaged due to contact with the surface.
In addition, a bottle unit is used as the bag body 102 for the root hardening method, and this is a bag made of a Russell net using a recycled polyester fiber having excellent strength characteristics, abrasion resistance, weather resistance, and the like. Is the body.
At the time of attaching the bag body 102, it is confirmed that the bag body is not damaged, and care is taken so that the bag body does not come off from the mold when the filling material 103 is inserted.

  The filling material 103 is appropriately selected according to various local conditions such as locally generated materials, purchased materials, and concrete lumps (50 mm to large particle size).

In addition, there is a filling material with sharp corners such as crushed stone, and when the bag body is detached from the formwork, the bag body may be damaged by rubbing friction, so the inner wall surface of the formwork 101 as a cushion It is practiced to attach a suction preventive material (ie, a friction preventive material) having a thickness of about 5 to 10 mm.
When the sucking prevention material is used in this way, when the bag body 102 is taken out of the mold frame 101, the surface of the mold frame and the filling material 103 come into contact with each other, and there is a risk of damaging the bag body interposed therebetween. It is because it can prevent as much as possible.

Next, as shown in FIG. 12 (B), using a backhoe (not shown) or the like, the filling material 3 is scooped up from the crushed stone pile and put into the bag set in the mold.
When this operation is repeated a plurality of times, a predetermined amount of filling material 103 is filled in the bag.

  When the filling of the filling material is completed, the mouth portion of the bag body 102 is tightened with a mouth-drawing rope.

Next, using a truck crane or the like, the bag body filled with the filling material is lifted and removed from the mold 101.
This completes the filling of the filling material.

However, since the above-mentioned formwork 101 is made of a steel plate, it is heavy, and therefore, a crane or the like is always required to load it on a dump truck or install it at a work site, which takes time and effort.
In particular, in a work site where a truck crane or the like cannot enter, it is extremely difficult and limited to install the mold 101.
In addition, the cost of manufacturing the mold itself is high and not economical.

Furthermore, since the mold 101 is made of a steel plate, when the filling material 103 is put in, it is necessary to look in from above the mold to check the amount of filling, and the heavy equipment operator puts in the filling material. It was difficult to check the content.
For this reason, there is a disadvantage that other workers are required for confirmation.
On the other hand, when the bag body 102 is pulled up after the filling material is added, there is a risk that the filling material 103 rubs and damages the bag body.
Although it is somewhat effective to attach the above-described sucking prevention material to the mold 101, it is impossible to completely avoid the damage.

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 is relatively light and easy to install, and even when inserting the filling material, the heavy equipment operator can reliably visually check the content of the filling material in the bag, and further, the bag body and the formwork It is an object of the present invention to provide a bag formwork that can avoid damage due to rubbing and a filling material charging method for a root hardening construction bag.

  According to the present invention, the bag formwork A includes the bendable rectangular mesh sheet member 2 and the support frame 1 including the frame body, and can be tackled or removed in a cylindrical shape. Thus, the bag body mold A can be released from the bag body mold A without any trouble by opening the bag body mold A outward.

Further, there is no case where the bag body 3 for the root hardening method is rubbed against the bag form A and damaged.
Moreover, since the bag formwork is made of the frame bodies 1A and 1A that are not formed of a steel plate but a thin ridge as in the prior art, the weight can be significantly reduced and the manufacturing cost can be reduced.
In addition, if the bag formwork A is light, it is not necessary to use heavy machinery for transporting to a work site or installing it in a quarry, and it is possible to reduce labor, time, and cost.
Further, since the bag formwork A is composed of the mesh-like sheet member 2 and the support frame 1 made of the frame body, the bag body 3 for the rooting method can be visually recognized, and the degree of charging can be observed at all times to improve the work efficiency.
Further, by providing the mesh-like sheet member 2 with a mark line 22 that serves as a guide for the amount of the filling material 4, the amount of the input can be easily confirmed.

Moreover, since the bag form A is cylindrical, it can be easily moved by rolling the entire body sideways.
It is composed of a bendable rectangular mesh sheet member and a support frame made of a pair of semi-cylindrical frame bodies, and the mesh sheet member and the support frame that are curved and cylindrical are attached and fixed to each other, Since the support frame is rotatable with a part of the mesh sheet member as a hinge portion, the bendable rectangular mesh sheet member 2 is a support frame 1 made of semi-cylindrical frame bodies 1A and 1A. Because it is supported and reinforced, deformation does not occur.

[Embodiment 1]
Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings.
FIG. 1 shows a bag formwork A according to an embodiment of the present invention.
The form frame A for a bag includes a support frame 1 composed of a pair of semi-cylindrical frame bodies 1A, 1A, and a bendable rectangular mesh sheet member 2.
The mesh sheet member 2 and the pair of support frames 1 are attached and fixed to each other.

[Mesh sheet member]
2A and 2B are diagrams showing the mesh-like sheet member 2, in which FIG. 2A shows a flat plate state, and FIG. 2B shows a cylindrically curved state.
The mesh sheet member 2 is a curved rectangular sheet member 2 having a mesh (multiple holes), and becomes cylindrical when both ends (one end side end 21 and the other end side end 21) are opposed to each other. .
That is, both end portions 21 and 21 of the mesh-like sheet member 2 are butted or overlapped, and can be detachably coupled using a connecting member, so that it can be easily formed into a cylindrical shape.
Specifically, an insertion port 21A (for example, a ring hole) is provided in each of the side end portions 21 and 21, and a coupling rod 5 (for example, an eyebolt welding round bar) as a coupling member is commonly inserted into the insertion port 21A. Thus, both end portions 21 and 21 are connected.

As another method, the side end portions 21 and 21 of the mesh-like sheet member 2 can be tied and fixed using a wire member (rope, string, wire, or the like) as a connecting member.
If this mesh-like sheet member 2 is formed into a cylindrical shape, the filling material 4 can be sufficiently supported with a strong strength in the radial direction.
In addition, since the mesh-like sheet member 2 can be bent, the mesh-like sheet member 2 can usually be rolled up in a small size and is convenient for transportation and storage.

Incidentally, as the mesh sheet member 2, an Adem (trade name) sheet is usually used as an optimum sheet.
Adem is an embankment reinforcing material having a network structure in which aramid fibers (technola) with small creep deformation are combined with high-density polyethylene resin, and has a slight curvature.
Adem is small in elongation and has a sufficient effect on continuous load, and is excellent in impact resistance, weather resistance, chemical resistance, cold resistance and heat resistance.
Therefore, it can be used in any region regardless of whether it is a cold region or a warm region, and can sufficiently withstand the impact when the filling material 4 is put into the bag as will be described later. it can.

The mesh-like sheet member 2 is provided with a mark line 22, and this mark line can be provided, for example, by sewing a yellow tape with mesh mesh of the mesh-like sheet member 2.
By providing the mark line 22 in this way, as will be described later, when the filling material 4 is introduced, it can be used as a guide for the amount to be charged.
Therefore, the amount of filling material 4 that is always stable can be input, and the construction management is easy.

It should be noted that the mark line 22 has a color that is easy to see and has a high visibility so that it can be more easily visually confirmed by a heavy equipment operator.
It is also possible to clearly recognize the standard input amount and the limit input amount by providing a plurality of mark lines.
For reference, a mark line 22 is shown in FIG.

[Support frame consisting of a pair of semi-cylindrical frames]
FIG. 3 shows the support frame 1 composed of the frame bodies 1 </ b> A and 1 </ b> A, and shows a state before being attached to the mesh sheet member 2.
The support frame 1 has two divided semi-cylindrical frame bodies 1A and 1A (that is, a pair of semi-cylindrical frame bodies 1A and 1A), which are rigid bodies.
The frame bodies 1A and 1A of the support frame 1 are made of steel materials of a vertical rod 11B and a horizontal rod 11A, which are relatively thin rods, but are rigid but lightweight because they have a so-called ramen structure.
Further, since it is not made of a steel plate as in the prior art, it can be seen without being blinded, and the bag can be visually recognized as described later.
Usually, when the height of the support frame 1 is 1 m and the radius of curvature of the arc is 1 m, a capacity for introducing crushed stones by 2t to 4t can be formed inward.
The frame bodies 1A and 1A are attached and fixed to the mesh sheet member 2 having the cylindrical shape described above.

[Mounting and fixing of support frame and mesh sheet member]
FIG. 4 is a view for explaining an attachment state of the support frame 1 and the mesh sheet member 2.
Two divided semi-cylindrical frame bodies 1A and 1A, which are support frames 1, are arranged and attached and fixed to a mesh sheet member 2 that has been bent into a cylindrical shape.
In this case, the support frame 1 is preferably attached to the mesh sheet member 2 by using a wire 6 (rope, string, wire, etc.), but the fixing means can of course use a fixing tool such as a hook. It is.
Since the frame bodies 1A and 1A of the support frame 1 are ridges, they can be easily fixed to the mesh-like sheet member 2 using the wire 6.
In a state where the support frame 1 is attached to the mesh-like sheet member 2, the two divided semi-cylindrical frame bodies 1A, 1A of the support frame 1 are rotated by using a part of the mesh-like sheet member 2 as a hinge portion H. It becomes movable [see (A)].

Therefore, after the filling material 4 is put into the bag body for the root hardening method set in the bag formwork A, the formwork can be opened to the outside through the hinge portion H, and used for the root hardening method. The form body A for bag bodies can be easily opened from the bag body.
When the mesh sheet member 2 is generally formed in a cylindrical shape, the mesh sheet member 2 has a property of inclining in an oblique direction as shown in FIG.
However, in the bag formwork A of the present invention, since the mesh-like sheet member 2 is reinforced by the support frame 1, such a tilt phenomenon does not occur at all.
The form body A for the bag body is the total weight of the mesh sheet member 2 and the heavier frame bodies 1A, 1A, and the weight of the entire range can be transported manually, for example, The ease of handling can be greatly improved by setting the weight to 30 kg to 80 kg.

[Opening the formwork from the bag for the rooting method]
The form A for a bag body can be opened outward by releasing the connection between the side end portions 21 and 21 of the mesh-like sheet member 2.
Specifically, the connecting rod 5 (for example, eyebolt welding round bar) inserted in the insertion port 21A (for example, ring hole) provided in each side end portion 21, 21 of the mesh-like sheet member 2 is removed. Thus, the both end portions 21 and 21 of the mesh sheet member 2 are separated.
Then, when the bag body mold A is rotated in the direction of the arrow about the rear hinge portion H, the bag body mold A is opened, and the rooting construction bag body is opened.

[Method of charging the filling material]
Next, a method of putting the filling material 4 into the bag for the root-sealing method will be described in the order of steps with reference to the schematic diagram and the flowchart of FIG.
First, the support frame 1 and the mesh-like sheet member 2 are attached and fixed to each other, and the bag frame A is assembled.
The attachment method of the support frame 1 and the mesh-like sheet member 2 in this case is as described above.
The bag formwork A is installed at an appropriate position on the work site.
In this case, since the bag formwork A has a cylindrical shape, there is an advantage that the bag body can be easily moved and installed by rolling it horizontally.

Next, as shown in FIG. 6 (A), a bag body 3 (hereinafter simply referred to as a bag body) is set (that is, disposed) on the inside of the bag body form A. The
In addition, it is preferable that the bag body 3 is arrange | positioned so that it may hang down on the outer surface of the form A for bag bodies [arrangement process].
Specifically, the bottom of the bag 3 is grounded to the ground in the mold, and the mouth side of the bag 3 is held back to the outer surface of the bag mold A.

The size of the bag body 3 is preferably such that the opening end of the bag body 3 is close to the ground when attached to the bag formwork A as described above.
After the filling material 4 is put into the bag body 3 as described above, the shape when the bag body 3 is lifted becomes a spindle type, which is close to the axial target shape.
As a result, the load applied to the bag body 3 is stabilized, that is, it becomes nearly uniform in the circumferential direction, and the proof strength against the input amount of the filling material 4 in the bag body is increased.

Next, as shown in FIG. 6 (B), the filling material 4 is put into the bag body using a backhoe or the like that is a heavy machine in the bag body 3 in this state [filling material feeding step].
At this time, since the frame bodies 1A and 1A are made of steel and the mechanical strength of the support frame 1 is large, the sheet member 2 can be accurately held from the periphery.
Therefore, as shown in FIG. 5 described above, the phenomenon that the cylindrical sheet member 2 is inclined in the oblique direction does not occur.
Further, even if the filling material 4 is mistakenly carried into the bag body 3 and is dropped directly onto the bag formwork A, the bag body 3 is protected by the frame bodies 1A and 1A.

  The filling material 4, for example, crushed stone, can be appropriately supplied if it is prepared by being deposited at one corner of the work site such as a guard age.

Since the inner bag body 3 can be seen through the support frame 1 and the sheet member 2, the heavy machinery operator can visually check the amount of the filling material 4 put into the bag body 3, and can work with sufficient confirmation.
Therefore, it is not necessary for another worker to look into the formwork and check it, and the work efficiency is greatly improved.

Then, when the filling material 4 is put into a predetermined amount, for example, the mark line 22, the filling is stopped, and the mouth portion of the bag body 3 is tightened with a mouth squeezing rope as shown in FIG. Process].
Further, although not shown, a plurality of hanging ropes are attached to the side of the mouth-drawing rope.
This specific work is performed in a state in which the bag body 3 covered on the outside of the bag formwork A is lifted upward and held by one worker so as to bundle the opening side of the bag body. It is done as a member attaches a mouthpiece rope.

Next, the connection between the one end portion 21 and the other end portion 21 of the sheet member 2 is released.
That is, the connecting rod 5 (for example, eyebolt welded round bar) is removed from the insertion port 21A (for example, a ring hole) at each side end, and the connection between the side ends of the sheet member 2 is released.
Then, as shown in FIG. 6 (D), the frame opens when it is rotated in the opening direction, that is, in the direction of the arrow, around the hinge portion H behind the bag mold A.
In addition, although a part of the mesh-like sheet member 2 is usually a hinge portion H, when the rear ends of the two frame bodies 1A and 1A constituting the bag formwork A are connected to be rotatable, The mesh sheet member 2 and the support frame 1 serve as the hinge portion H.
By opening the bag body form A, the bag body 3 does not come into contact with the bag body form A and is in an open state [opening step].

Next, as shown in FIG. 6 (E), the bag body 3 is lifted by using a truck crane or the like to be detached from the bag formwork A [detaching step].
At this time, since the bag body 3 has already been freed without being restrained by the bag formwork A, no rubbing occurs between the sheet member 2 and the bag body 3 when the bag body 3 is pulled up. .
Therefore, it is possible to reliably prevent the bag body from being damaged due to the conventional rubbing phenomenon.
This completes the filling method of the filling material.

[Other Embodiment 1]
In the above-described embodiment, an example in which the mesh-like sheet member 2 is attached along the outer side surface of the cylindrical support frame 1 is shown. However, here, the mesh-like sheet member 2 is attached to the outer side surface and the inner side surface of the cylindrical support frame 1. The example attached along is shown.

FIG. 8 shows a bag formwork A having such a structure.
The mesh-shaped sheet member 2 is doubled by folding a rectangular sheet in half.
Thereafter, as in the example described above, a connecting member (not shown) is connected between the one end portion 21 (two free ends) and the other end portion 21 (bent) of the mesh sheet member 2. Through which it can be connected or removed.
Further, as shown in FIG. 9, the support frame 1 and the sheet member 2 are attached and fixed by inserting the support frame 1 from above into the gap between the double mesh sheet member 2 and finally inserting a wire rod or the like. It is attached and fixed to the sheet member 2 using.
Subsequent handling is the same as the above-mentioned example.
In this embodiment, since the sheet member 2 is doubled, the strength of the mold itself increases, and the support frame 1 and the sheet member 2 are more reliably integrated.
In terms of weight, since the sheet body itself is lighter than the support frame 1, even if the sheet member 2 is doubled, it does not become heavy as a whole bag frame.

[Other embodiment 2]
In the above-described embodiment, an example of a mesh-like sheet member that is curved and cylindrical as a mesh-like sheet member has been shown, but here, a pair of mesh-like sheet members that are curved and become semi-cylindrical are shown. An example is shown.
In this case, the mesh sheet member is attached along the inner side surface and the outer side surface of the semi-cylindrical frame body.

That is, as shown in FIG. 10, the mesh-like sheet member is attached so as to surround the semi-cylindrical frame body.
The support frame is rotatable at one end of the mesh sheet member.
Specifically, the connecting rod is inserted into the insertion port 21A formed at the end of the mesh sheet member, or the insertion ports 21A are coupled with each other by a wire rod so as to be rotatable.
As described above, the filling method of the filling material into the bag for the root hardening method in the other embodiments 1 and 2 can be performed in accordance with the example already described in FIG.

Although the present invention has been described above, the present invention is not limited to the above-described embodiment, and various other modifications can be made without departing from the essence thereof. .
For example, in the above-described embodiment, the frame bodies 1A and 1A are composed of the vertical rod 11B and the horizontal rod 11A.

In the above-described embodiment, the frame bodies 1A and 1A are made of steel. However, other metal materials may be used as long as they have a certain strength to reinforce the mesh sheet member 2.
However, it is also possible to employ a material having a strength equivalent to that of a metal material, for example, plastic.

  Furthermore, in the above-described embodiment, the length of the support frame 1 is shorter than that of the mesh sheet member 2, but it is naturally possible to have the same length.

  In the above-described embodiment, the case where the connecting rod is used to connect both side ends of the sheet member 2 has been described. However, it is also possible to connect using a hook or a wire.
