Description

Constructing method of Breakwater Structure using Tetrapod and Connecting Member}

The present invention relates to a method of constructing a sofa structure that protects a breakwater or a levee from waves by installing a tetrapod, and specifically, when a plurality of tetrapod end ends are gathered at one point, binding of a steel wire or the like is performed. By using ash to connect the ends of the tetrapods collected at one point to each other to achieve mechanical integration between the ends of the plurality of tetrapods, the sofa structure by the plurality of tetrapods is more firmly constructed, and further improved. The present invention relates to a method of constructing a sofa structure by using a new method of binding material in which a tetrapod is laminated in a plurality of layers so as to exhibit a breaking effect, and a multi-layer installation of the tetrapod.

In order to protect breakwaters and embankments from waves and waves, the sofa structure is constructed by installing tetrapods. Korean Patent No. 10-0649137, which is introduced below as a prior patent document, introduces a conventional technique for constructing a breakwater using such a tetrapod.

In constructing a sofa structure by arranging a plurality of tetrapods having four leg portions, it may be necessary to build a sofa structure by stacking tetrapods in multiple layers. FIG. 1 discloses a drawing substitute photograph showing a state in which a sofa structure is formed by stacking tetrapods in two layers according to the prior art, and FIG. 2 shows a Korean Patent No. 10-0649137, which is introduced below as a prior patent document. As shown in the accompanying drawings of the specification has been disclosed a view showing a structure for stacking the tetrapod in three layers by the prior art. 1 and 2, conventionally, in stacking tetrapods in multiple layers, three legs are laid and the other leg is arranged by horizontally arranging a plurality of tetrapods adjacent to each other in a vertical direction. The first leg is formed, and the three legs of the tetrapod are laid down while the other leg is vertically inverted to face down with the tetrapod of the first layer. Between the sections, a second layer was formed in such a manner that the tetrapods of the second layer were arranged so that the vertically downward leg portions of the tetrapods of the second layer were located.

However, in this way, the tetrapod of the first layer is disposed so that one leg is vertically upward, and the tetrapod of the second layer is inverted so that one leg is vertically downward, and the tetrapod is laminated and installed in multiple layers so as to be sandwiched between the tetrapods of the first layer. In the method, the following problems arise.

First, tetrapods are easily broken. In the case of stacking tetrapods in multiple layers according to the prior art, the tetrapods of the second layer are located at the center of gravity of the second layer, whereas the tetrapod weight is vertically lowered with one leg, and the tetrapods of the first layer are adjacent to each other. It is a state supported by. Therefore, there is a problem in that the tetrapod is shaken by the waves, the possibility of breakage while leaving the position installed in the first place is very high.

Second, there is a limit that the breaking function is not large. In the case of stacking the tetrapods in multiple layers according to the prior art, the tetrapods of the second layer form the upper surface of the sofa structure with three leg portions forming one plane at one end thereof. In other words, the upper part of the tetrapod of the second layer is in a state where there is little protrusion on the surface as a whole. Therefore, when the waves invade, there is a limit that the wave easily rises on the upper surface of the second layer tetrapod with less protruding, and the breaking effect is insufficient. In particular, as shown in FIG. 2, when stacked in three layers, the tetrapods in the third layer simply lie on the top surface made by the second layer tetrapod, without any mechanical bonding with the tetrapods of the second layer. There is a problem that only the third layer tetrapod is lost during the wave invasion.

Third, there is a limit of low risk and efficiency at work. When stacking tetrapods in multiple layers according to the prior art, the second layer tetrapods should be supported by the tetrapods of the first layer located adjacent to the center of gravity of the second layer tetrapods at the same time, and thus in this state. When installing the second layer tetrapod, there is a high risk of the tetrapod conducting, there is a problem that the efficiency of the installation work is lowered because of the difficulty in the work.

Fourth, there is a limitation that tetrapods cannot be laminated in three or more layers. That is, when the second layer tetrapod is stacked upside down as shown in FIG. 2, the upper surface of the sofa structure stacked and constructed is flat. Therefore, when the third layer of tetrapods are additionally stacked thereon, the third layer of tetrapods is not bound to the second layer of tetrapods at all and is simply placed on a flat surface, thereby preventing the breaking wave function. Therefore, in the case of stacking the second layer tetrapod upside down according to the prior art, there is a limit that the maximum stacking number of tetrapods can be laminated is limited to two layers.

Fifth, the biggest problem is that the binding force between the tetrapods is weak. The tetrapods of the first layer adhere to their position only by their own weight and their own weight acting from the tetrapods of the second layer, and the tetrapods of the second layer adhere only by their own weight. That is, since there is no binding between the tetrapods in each layer, there is a limit that the binding force and stability of the tetrapods are low.

See FIG. 4C of Korean Patent Registration No. 10-0649137 (November 27, 2006).

The present invention has been developed to solve the problems of the prior art as described above, specifically, in the construction by stacking tetrapods in multiple layers to build a sofa structure, the position of the center of gravity of the tetrapods installed in the second layer is high It prevents the positional displacement of the second layer tetrapod caused by the presence and the damage thereof, and further reduces the risk of the tetrapod falling when installing the second layer tetrapod, and makes the installation easy to perform. The purpose is to improve.

In addition, an object of the present invention is to improve the breaking performance by making the upper surface of the sofa structure in a rough state rather than a smooth state when installing the sofa structure by installing a tetrapod in a double layer.

In addition, an object of the present invention is to be able to freely build a sofa structure of the desired height by making a solid bond between the tetrapods of the upper and lower layers while stacking the tetrapod in a double layer as the desired number of layers.

In particular, it is an object of the present invention to improve the stability of the sofa structure constructed by tetrapods by integrating the binding material between the tetrapods of each layer.

In order to achieve the above object, in the present invention, tetrapods composed of members having four legs extending to have the same angle to each other are laminated in a plurality of layers, each of which has a ring at the end of each leg A member is provided; When the tetrapods of each layer are installed, the sofa structure is formed by stacking the tetrapods in a plurality of layers while binding the binding material to the ring member and integrating the ends of the legs of the plurality of tetrapods at a position where the ends of the legs of the plurality of tetrapods gather. Constructing; When stacking the tetrapods, three of the four legs of the tetrapods are extended in the transverse direction, respectively, so that the ends of the plurality of first layer tetrapods so that the end is in contact with the mounting surface and the remaining one is vertically upward. Installing adjacently in the transverse direction; And a plurality of second layer tetrapods are respectively lifted so that a second layer tetrapod is supported by three legs of the first layer tetrapod between the plurality of first layer tetrapods, and among the four legs of the second layer tetrapod. Inserting between the first layer tetrapods such that the three legs extend in the transverse direction and the other one is disposed vertically upward; There is provided a method of constructing a sofa structure using tetrapods, wherein the sofa structure is constructed by stacking tetrapods in a plurality of layers.

In the present invention, following the disposing step of the second layer tetrapod, the tetrapod of the additional layer is lifted so that three of the four legs of the additional layer tetrapod extend in the transverse direction and the other one leg. The part may be inserted and disposed between the plurality of second layer tetrapods in a state of being vertically upward, and the step of stacking additional layers of tetrapods on the second layer tetrapods may be repeatedly performed up to the height of the sofa structure.

According to the present invention, in stacking tetrapods in multiple layers, the stacked tetrapods are not inverted as in the prior art, but are disposed between the lower tetrapods with three leg portions positioned downward, so that the center of gravity of the upper tetrapods is inverted. Rather, it is located at the lower side, thereby preventing the occurrence of tetrapod conduction in the installation process of the upper layer tetrapod, and it is possible to install the upper layer tetrapod stably, safely and quickly, thereby improving the installation efficiency. Is exerted.

In addition, in the present invention, the upper surface of the sofa structure constructed by stacking tetrapods is made to be rougher than the prior art in which the upper layer tetrapods are placed upside down. The effect of further improving performance is exerted.

Particularly, in the present invention, a plurality of tetrapods arranged in each layer are formed by the tetrapods by the ends of the leg portions which are gathered in one place are mechanically bound to each other by a binding material so that the tetrapods in each layer are integrated with each other. The effect of improving stability is also exhibited.

In addition, in the present invention, the tetrapods are repeatedly laminated in a plurality of layers without the inverted tetrapods, and thus the tetrapods of various layers can be stably stacked in accordance with the height of the desired sofa structure.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. Although the present invention has been described with reference to the embodiments shown in the drawings, it is to be understood that the technical idea of the present invention and its essential structure and operation are not limited thereby.

Prior to explaining the specific process of the sofa structure construction method according to the present invention, a tetrapod (1) having a grout bag binding structure newly proposed in the present invention and applied to the construction method of the present invention will be described. When describing the prior art for convenience, the same reference numeral (1) used to refer to the conventional tetrapod was used in the same way for the tetrapod of the present invention.

Figure 3 is a schematic perspective view of the tetrapod 1 is provided with a bridge member 11 that can bind the binding material to be used in the construction method according to the invention. As shown in the figure, the tetrapod 1 according to the present invention is constituted by a member having four legs extending in the same shape as the conventional one to have the same angle to each other. However, unlike the prior art, each leg end is provided with a ring member 11 to which the binding material 12 such as steel wire or chain can be integrally provided. That is, the end member in the direction in which the leg portion extends from each leg end is provided with a ring member 11 to which the binding material 12 can be bound.

The ring member 11 may be provided on the end surface of the leg portion of the tetrapod 1 in various forms and by various methods. For example, when the tetrapod 1 is manufactured, the reinforcing bars are placed on the leg portions, but the reinforcing bars After placing concrete to be exposed to the outside of the tetrapod to form the tetrapod formwork to produce a tetrapod (1), the formwork is deserted, and the ring member 11 made of steel and welded with the reinforcing bar reinforced to the tetrapod or coupler There is a method of integrating by a method such as combining. In another method, the loop member is placed in the formwork for the tetrapod and the concrete is placed to cure the concrete with the end of the loop member embedded in the concrete. You can also In addition to these methods, when the tetrapod concrete is poured into the tetrapod formwork, a nut-type landfilling device having a threaded portion is installed in the formwork, and the tetrapod is manufactured so that the landfilling device is embedded in the tetrapod concrete. The bolt member formed in the form of screwing the ring member and the buried device, the ring member may be installed in the tetrapod. However, the manner illustrated above is an example of various methods for providing the ring member in the tetrapod, and in the present invention, the method of integrally installing the ring member in the tetrapod is not limited thereto.

Next, a detailed process of the tetrapod construction method according to the present invention will be described with reference to FIGS. 4A to 4C, 5, 6A to 6C, and 7. 4A to 4C are views illustrating a state in which a plurality of first layer tetrapods are disposed on a slope of a levee in the tetrapod construction method according to the present invention, FIG. 4A is a schematic perspective view, and FIG. 4B is a schematic side view. FIG. 4C is a schematic plan view as seen from arrow B of FIG. 4B. 5 is a schematic enlarged view of a portion A of FIG. 4A.

As shown in Figs. 4A to 4C, first, a plurality of tetrapods are disposed on the bank slope. For the purpose of distinguishing tetrapods arranged as the first layer on the bank slope, that is, tetrapods arranged as the first layer, from tetrapods arranged as another layer thereon, it is referred to herein as "first layer tetrapod 10" for convenience. . As described later, tetrapods stacked on the first layer tetrapod 10 are referred to as "second layer tetrapod 20" for convenience. Of course, when the first layer tetrapod and the second layer tetrapod are collectively referred to as "tetrapod (1)".

As shown in Figs. 4A to 4C, the first layer tetrapod 10 has three leg portions extending in the transverse direction so that its ends touch the installation surface (the bank inclined surface in the drawing) and one leg portion is vertically upward. The plurality of first layer tetrapods 10 are densely installed so that there are no empty spaces in the lateral direction if possible. At this time, as shown in FIG. 5, in the position where the leg ends of the plurality of first layer tetrapods 10 are gathered, the binding member 12 such as a chain or a steel wire is placed at the leg ends of the respective tetrapods 10. It is coupled to the ring member 11 provided in the cross section. That is, after arranging the first layer tetrapod 10, the binder 12 is placed at the end of the leg of the first layer tetrapod 10, and the end of the binder 12 is bound to the ring member 11. The end portions of the legs of the plurality of first layer tetrapods 10 are bound together by the binding material 12 and are integrated. Therefore, when an external force is applied to one first layer tetrapod 10, the external force is transmitted to the other first layer tetrapod through the ring member 11 and the binding material 12 at the end of the leg, thereby dispersing the external force. Therefore, the effect that the occurrence of the phenomenon that the tetrapod leaves the position originally installed by the external force is suppressed is exhibited.

As shown in FIGS. 4A to 4C, the first layer tetrapod 10 is provided, and the first layer tetrapod 10 is mechanically bound to each other by the binding material 12, and subsequently, FIGS. 6A to 4C. As shown in 6c, the second layer tetrapod 20 is provided. 6A to 6C are views corresponding to FIGS. 4A to 4C, respectively, and FIG. 6A shows a second layer tetrapod 20 installed thereon in a state where a plurality of first layer tetrapods 10 are installed. 6B is a schematic side view of the state in which the second layer tetrapod 20 is installed, and FIG. 6C is a schematic plan view seen from the arrow D direction of FIG. 6B. FIG. 7 is a schematic enlarged view of a portion C of FIG. 6C.

As shown in Figure 6a to 6c, in installing the second layer tetrapod 20, in the present invention, rather than installing the tetrapod upside down, the three legs are located in the lower position and one leg is extended vertically upward The second layer tetrapod 20 is provided. That is, the 2nd layer tetrapod 20 is a shape supported by three leg parts of the 2nd layer tetrapod 20 similarly to the 1st layer tetrapod 10, and is lifted by the lifting apparatus 100, such as a crane. As shown in FIG. 6B, the space between the first layer tetrapod 10 is positioned. At this time, as shown in Figure 6c, the second layer of the tetrapod 20 also the end of the leg portion of the second layer tetrapod 20 adjacent to each other in the lateral direction like the first layer tetrapod 10 is gathered to one point There will be a place.

In this way, at the position where the leg ends of the plurality of second layer tetrapods 20 are collected, the ring member 11 and the binding member 12 are formed in the same manner as described above with respect to the first layer tetrapod 10. The leg ends of the two-layer tetrapod 20 are integrated with each other. Therefore, when an external force is applied to the second layer tetrapod 20, the second layer is transmitted to the other second layer tetrapods which are integrated with each other via the ring member 11 and the binding member 12, and the external layer is dispersed to receive the external force. The phenomenon that the tetrapod 20 is separated is suppressed. That is, the stability of the second layer tetrapod 20 is greatly improved.

In particular, in the present invention, since the second layer tetrapod 20 is not inverted as described above and is disposed between the first layer tetrapod 10 with the three leg portions positioned downward, the center of gravity of the second layer tetrapod 20. This is located below the inverted state, thereby preventing the occurrence of the tetrapod conduction in the installation process of the second layer tetrapod 20, and stably and safely and quickly the second layer tetrapod 20 ) Can be installed to improve the efficiency of installation work.

In addition, since one leg portion of the second layer tetrapod 20 is vertically disposed in a state in which the second layer tetrapod 20 is stacked on the first layer tetrapod 10, that is, the upper surface of the second layer tetrapod 20, namely, The upper surface of the stacked sofa structure is made rougher than the prior art in which the second layer tetrapod is placed upside down, thereby increasing the frictional resistance between the wave and the sofa structure when the wave is invaded, thereby further improving breaking performance. Effect is exerted.

In particular, in the case of the second layer tetrapod 20, one leg portion disposed vertically upward may be made longer than the remaining three leg portions. FIG. 8B is a view corresponding to FIG. 6B, in which one leg portion vertically disposed longer than the other leg portion is formed on the first layer tetrapod 10 using the second layer tetrapod 20. An embodiment of the invention is shown. As shown in the embodiment shown in Figure 8, when the vertically disposed leg portion is formed longer than the other leg portion of the tetrapod to be laminated on the first layer tetrapod 10 by using it as a second layer tetrapod, By increasing the roughness of the upper surface of the sofa structure is laminated to maximize the frictional resistance between the wave and the sofa structure can be significantly improved the breaking performance.

Furthermore, as described above, the plurality of tetrapods arranged in each layer have end portions of the legs, which are gathered in one place, are mechanically bound to and integrated with each other by the ring member 11 and the binding material 12, and thus, within each layer. The binding force between the tetrapods is greatly improved, whereby the stability of the sofa structure constructed by the tetrapods is also improved.

On the other hand, as described above, after the second layer tetrapod 20 is laminated, the third layer tetrapod is additionally formed in the same manner as the second layer tetrapod, that is, the second layer tetrapod without the inverted tetrapod as necessary. Additional tetrapod layers can be formed in between, and by repeating this process, multiple layers of tetrapods can be stably stacked to suit the height of the desired sofa structure. That is, the additional layer tetrapod can be installed on the second layer tetrapod 20 in the same manner. According to the construction method of the present invention, since the three leg portions extending in the transverse direction of the second layer tetrapod 20 are interposed between the vertical leg portions of the first layer tetrapod 10, the first layer tetrapod It has a strong binding force against the external force in the horizontal direction between (10) and the second layer tetrapod 20, the third layer tetrapod can be provided in the same manner above the second layer tetrapod 20, a plurality of more Tetrapod can be laminated in a state having a strong binding force of the upper and lower layers, there is an advantage that can be constructed sofa structure of the desired height.
