Description

Reinforced fiber stone-bag}

The present invention relates to a fiber stone-r that is dropped underwater, and in particular, to a reinforced fiber stone-r widely used in fields such as coasts, roads and forests, centered on aquatic environments.

Fiber Stone-r is widely used in aquatic environments, such as revetment, prevention of coastal erosion, creation of natural rivers and anchors of pollution prevention nets.

Basically, a ssamzie-shaped Russell network can be defined as a fiber stone-r or a fiber gabion, and the fiber stone-r is filled with aggregate and the like.

However, since the fiber stone-r is made of flexible fiber and the outer shape of the fiber stone-r is freely deformed when the aggregate is accommodated, there is a problem in that it is impossible to manufacture a fiber stone-r of a certain standard.

Furthermore, if the upper end of the Fiber Stone-r is lifted with a crane to install the Fiber Stone-r, the external shape of the Fiber Stone-r can be freely deformed, which increases the possibility of damage, such as stress concentration. have.

Here, after the fiber stone-r is dropped into the water, it is in a situation where it is affected by the flow of a fluid such as seawater.

Because fiber stone-r is flexible, in an underwater environment, the aggregate accommodated in the fiber stone-r also fluctuates according to the strong flow of fluid.

Alternatively, the aggregates may cause friction within the Fiber Stone-r, causing damage to the fibers, thereby reducing the durability of the Fiber Stone-r.

On the other hand, there are cases where the Fiber Stone-r needs to be removed, such as being used in temporary underwater construction environments.

In the case of demolition, the load of the fiber stone-r is greatly increased because sand, mud, etc. fill the gaps in the internal aggregate of the stone-r compared to the case of the initial salvage.

Therefore, the used fiber stone-r has a very high risk of breakage, and in the past, it is very rare to reuse such a fiber stone-r.

An object of the present invention is to provide a reinforced fiber stone-r that can be manufactured to a certain standard.

In addition, an object to be solved is to provide a reinforced fiber stone-r in which each mesh of the fiber stone-r can maintain its shape without being deformed freely.

And, an object to be solved is to provide a reinforced fiber stone-r in a shape that allows the load of aggregate accommodated in the fiber stone-r to be dispersed without being concentrated on a specific part.

Furthermore, the task to solve is to provide a reinforced fiber stone-r that can support a load five times or more than that of the fiber stone-r at the time of initial lifting.

Finally, an object to solve is to provide a reinforcing fiber stone-r that can be reused by strengthening the strength of the side part of the fiber stone-r where the load is concentrated.

Reinforced fiber stone-r according to the present invention contains aggregate inside and is divided into a side network, an upper network and a lower network. A side network reinforcement rope connected along the perimeter of the lower net so that a pair of inlet suture ropes connected along the circumference of the upper net and the lower end of the lower net can be maintained inside the fiber stone r and a lower tightening rope connected along It is characterized in that it is gradually reduced.

Here, the backing network is characterized in that it is padded so that the mesh of the side network and the mesh of the backing network are shifted.

In addition, the side network reinforcing rope passes through the meshes of the side networks and the backing networks along the perimeter of the side networks and the backing networks to alternately pass the meshes of the side networks and the backing networks to maintain a shifted state. .

Finally, the upper net is overlapped by folding outward of the fiber stone-r, and the inlet suture rope is connected along the circumference of the overlapped upper net so that the overlapping state of the upper net is maintained.

The reinforced fiber stone-r according to the present invention has the effect of allowing the fiber stone-r to be manufactured in a regular disc shape through the tightening positions of the inlet suture rope, the side network reinforcement rope, and the lower tightening rope.

And, there is an effect that the load of the aggregate accommodated in the fiber stone-r is distributed without being concentrated on a specific part through the predetermined standard of the disk shape.

In addition, the side network reinforcing rope is connected to cross each mesh of the upper network and the padding network, so that each mesh is free to deform and maintain its shape.

Furthermore, it has the effect of strengthening the strength of the lifting tree through the structure in which the upper net is folded outward, so that it can support a load five times more than that of the Fiber Stone-r at the time of initial lifting.

Finally, by strengthening the strength of the side network of Fiber Stone-r, where the load is concentrated through the reinforcement network, it not only increases durability, but also increases the ease of maintenance, which has the effect of smoothly reusing the Fiber Stone-r.

Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings, and in the drawings and detailed description, drawings and descriptions of configurations and actions that can be easily understood by those skilled in the art from the general technical configuration are abbreviated or omitted.

In particular, in the illustration and detailed description of the drawings, the detailed description and illustration of the specific technical configuration and action of elements not directly related to the technical features of the present invention are omitted, and only the technical configuration related to the present invention is briefly illustrated or explained.

Reinforced fiber stone-r (hereinafter referred to as 'stone-r') according to the present invention is a structure widely used mainly in aquatic environments, such as revetment, coastal erosion prevention, natural river formation, and contamination prevention net anchor.

First, the overall shape of the Stone-r according to a preferred embodiment of the present invention will be described with reference to FIG. 1 .

1 is a view of a state being lifted by a crane, etc. in a state in which aggregate is accommodated in a stone-r according to an embodiment of the present invention (a) as viewed from the side in an upward inclined direction, (b) as viewed from the bottom It's a photo.

As shown, the stone-r according to the present invention is an integrally integrated Russell network, and the aggregate accommodated therein maintains a complete disk shape.

The stone-r formed in the disk shape as described above can evenly distribute the load of the aggregate accommodated therein in the same direction as ① to ③ of FIG. 1 .

Hereinafter, the formation structure of the stone-r for the above functions will be described.

2 is a conceptual diagram of a reinforced fiber stone-r according to an embodiment of the present invention.

The stone-r is formed as an integral Russell network as described above, but hereinafter, for convenience of explanation, the stone-r is divided into a side network 100, an upper network 110, and a lower network 120 according to the location. Explain.

In detail, the stone-r is a side network 100, an upper network 110, and a lower network 120 divided into the Russell network, as described above, with the reinforcement network 200 and the side network reinforcement rope 300, inlet suturing The rope 400 and the lower tightening rope 500 are included.

The padding network 200 is connected and coupled by padding along the circumference of the side network 100 by stitching.

Referring to FIG. 1 , if aggregate is accommodated in Stone-r, a relatively strong lateral pressure load acts on the side network because the largest amount of aggregate is located in the side network.

Therefore, as shown in FIG. 2 , the side network can be reinforced by attaching the backing network 200 along the circumference of the side network 100 and connecting the stitching together.

In more detail, the reinforcement of the side network can be connected by stitching by padding so that the mesh of the side network and the mesh of the padding network are shifted.

That is, when the largest amount of aggregate is accommodated in the side network, a high lateral pressure is applied to the side network, so that the side portion can be reinforced by connecting the padding room as described above.

In addition, since the structure as described above fills the damaged space of the side network even if the side network is damaged during use, the possibility of loss of aggregate can be reduced.

And, since Stone-r can maintain its original original shape even during repair work, it can be restored to a state that can be easily reused by simply repairing only the damaged part.

The effect of this padding network can be further maximized through the side network reinforcement rope 300 .

The side network reinforcement rope 300 is connected along the circumference of the side network and the backing network, and when the aggregate is accommodated in the stone-r, the side network is expanded in the radial direction.

Accordingly, the maximum diameter of Stone-r can be adjusted by adjusting the length of the side network reinforcement rope, and the flatness (0<e<1) of Stone-r can be adjusted.

That is, as the length of the side network reinforcement rope becomes longer, the stone-r can be constructed in a flat form so that the flatness converges to 1. The length of the side network reinforcement rope can be adjusted according to the amount of aggregate to be accommodated.

Here, the side network reinforcement rope is connected along the periphery of the side network and the backing network, and are alternately connected while passing through the meshes of the side network and the backing network.

As described above, each mesh is crossed through the backing network 200, but since each mesh is a flexible fiber material, there is a limit to maintaining a staggered state in water only by padding the backing mesh.

Therefore, since the side network reinforcement rope crosses the side network and the padding network, each mesh can be maintained in a staggered state by the frictional force of the portion where each mesh and the side network reinforcement rope contact.

Through this, since each mesh can maintain its shape without being deformed freely even in the water, it is possible to prevent the loss of the aggregates accommodated by the stone-r.

Furthermore, since the side network reinforcement rope presses the side network in the radial direction, it holds the aggregates so that they do not move within the stone-r.

Through this, it is possible to prevent the aggregate from deteriorating the durability of the stone-r, such as friction with the stone-r, which is generated when the aggregates fluctuate inside by the strong flow of the fluid.

That is, unlike the conventional stone-r, the reinforced fiber stone-r according to the present invention is a reinforcing type of fiber stone-r that is reusable, and it is a very important technical idea not to decrease strength as well as durability.

Next, the inlet suturing rope 400 is configured to form a pair and wrap the upper network around the perimeter to seal the inlet.

In particular, in the case of the upper network, referring to FIG. 1 , when the Stone-r is lifted by a crane, etc., it can be confirmed that the upper network is stretched and gathered in the central direction, and thus the load is concentrated to the upper network.

3 is an enlarged view of the upper network of Stone-r according to an embodiment of the present invention. Referring to this, the upper network may be folded outwardly to overlap the upper network in order to increase the strength of the upper network.

And, it can be connected along the circumference of the overlapped upper network with the inlet suture rope so that the overlapping state is maintained.

Here, as the number of overlaps increases, the strength of the upper network becomes stronger, but the surface area of Stone-r decreases, so the amount of aggregate that can be accommodated decreases.

Therefore, the optimum number of overlaps can be adjusted by predicting and considering the load of the aggregate and the strength due to the load to be increased during lifting.

Next, referring to FIGS. 1 and 2 , the lower tightening rope 500 is connected along the periphery of the lower network, and in order to form a flat bottom surface of the stone-r, the lower network of the stone-r is moved inward. In the retracted state, it should be connected along the circumference of the retracted part.

As a result, the tightening position of the lower tightening rope acts as a central axis inside the Stone-r, so that it can eventually form a disk shape of a certain standard no matter what form the aggregate is filled in.

In more detail, when the upper network and the lower network are tightened by the inlet suturing rope 400 and the lower tightening rope 500, the horizontal cross-sectional area of the stone-r increases toward the tightening position of the inlet suturing rope and the lower tightening rope, respectively. It is configured to be reduced, and through this, a disk shape of a certain standard is achieved.

Next, although there is a lifting rope (not shown) used to lift the Stone-r in the configuration of the Stone-r, it will be described together in the manufacturing and construction process to be described later.

This concludes the description of each configuration. Next, the manufacturing and construction process of Stone-r will be described.

4 is a view for explaining the manufacturing and construction process of the stone-r according to an embodiment of the present invention.

The stone-r is a Russell network, and in order to manufacture a preferred embodiment according to the present invention, the lower end of the lower network of stone-r is first introduced into the interior of the stone-r.

The lower net is sutured using the lower tightening rope, and through this, the lower end of the lower net is maintained inside the Stone-r.

Next, along the perimeter of the side mesh, the backing mesh is stitched together. Here, the side reinforcement rope is connected along the circumference of the side network and the padding network.

Next, after wrapping the stone-r in a rectangular box as shown in Fig. 4 (a), a large amount of aggregate is placed in the box.

Thereafter, the upper network of the stone-r is sutured using an inlet suturing rope as shown in FIG. 4 (b).

At this time, as in FIG. 3 , the upper net may be folded outwardly along the circumference of the upper net to overlap, and the number of overlaps may be adjusted according to the weight of the aggregate.

Next, tighten the entrance of Stone-r by pulling a pair of inlet suturing ropes to both sides like Ssamji, and repeatedly wind the inlet suturing rope around the entrance so that the suture is firmly fixed.

Next, a lifting rope (not shown) that is used to lift the Stone-r and connects the Stone-r and the crane may be provided.

In the completely sealed Stone-r, the upper net remains above the inlet seaming rope, and the lifting rope is passed through the mesh of the remaining upper net, and loops are formed at both ends of the penetrating lifting rope so that it can be coupled to the crane. .

In detail, the position where the lifting rope passes through the mesh of the upper mesh is preferably connected to the mesh located at least second from the top rather than the top of the upper mesh.

Through this, even when the mesh through which the lifting rope passes is damaged, the mesh remaining on the upper side exists, so that it is possible to prepare for a safety accident.

In addition, there is a method of adjusting the number of penetration points in order to strengthen the strength of the lifting rope.

The simplest is that the lifting rope passes through two points of the upper net, or it can be configured by passing through four points of the upper net to further strengthen the strength of the lifting rope.

In order to strengthen the strength of the original rope, there is a method of making the thickness of the rope thicker, but there is a limit to increasing the thickness, and the strength can be supplemented by increasing the penetrating points. can

Reinforcing the strength of the lifting rope is very important, and since the load is significantly increased during demolition than when the Stone-r is initially dropped underwater, the configuration to reinforce the strength of the lifting rope is very important.

In addition, as described above, unlike the conventional stone-r, the reinforced fiber stone-r according to the present invention is configured to be reusable, and it is preferable to design it in consideration of the load at the time of demolition.

Next, as shown in Fig. 4 (c), the crane ring is bound to the ring shape formed by the lifting rope and transported, and after loading on the barge as shown in Fig. 4 (d), to the drop position as shown in Fig. 4 (e) It is lifted, and finally, it undergoes a process of dropping as shown in FIG. 4 (f).

This concludes the description of the manufacturing and construction process, and finally, we want to prove the excellent effect of the present invention through comparative experimental data with other Stone-r. 5 to 6 are comparative photos and experimental data with other Stone-r.

Referring to FIG. 5 , since the aggregate inside the turret stone-r on the right is not uniformly distributed, the possibility that the load will be concentrated in a specific location is very high.

Since the risk of breakage of Stone-r is very high due to the concentration of loads, the amount of aggregate that can be loaded is inevitably reduced.

On the other hand, the reinforced fiber stone-r according to the present invention is formed of the left disk-shaped stone-r.

Through this, the load is evenly distributed around the Stone-r, so it can accommodate a much larger amount of aggregate compared to the turret-type Stone-r, so it can be used more diversely.

In order to prove this, let's look through the experimental data of FIG. 6 . 6 shows comparative data, such as maximum stress, deformation amount, etc. of the disk-type and the turret-type fiber stone-r.

In the case of the disk type related to the present invention, it can be seen that very low stress is applied to the curved portion at 0.40023 MPa and 0.3927 MPa.

In addition, the deformation amount also shows a lower deformation amount value of about 17% compared to the deformation amount of the bag type.

This amount of deformation appears in the same way even after being dropped into the water, so that a uniform load distribution is formed.

As described above, the present invention has a main technical idea to provide a reinforced fiber stone-r, and since the embodiments described above with reference to the drawings are only one embodiment, the true scope of the present invention is determined by the claims it should be

100: side network
110: upper network
120: lower network
200: padding net

400: entrance suture rope
