The present invention relates to a breakwater structure that is constructed at sea for the purpose of maintaining the calmness of the sea level by preventing the waves from the sea, especially the clean seawater of the open sea can be introduced into the inland sea through the circulation passages. Seawater circulation that can prevent and protect the vessels and various water facilities anchored in the port from blue waves by effectively blocking the seawater coming from the open sea through the curved rounded concave upward toward the open sea. And it relates to an upright breakwater structure having an anti-glare function.

Breakwater, a facility outside the port, keeps the sea level at sea level by preventing the blue sea from the sea, and is a facility for protecting various waterworks facilities by promoting safety during the operation of ships, cargo, and unloading.

The breakwater for this purpose is constructed in the proper structure and size according to the port conditions, location, and scale of the breakwater, but most of the breakwaters currently constructed are designed to block the inflow of seawater from the sea to the inland sea. Water pollution and environmental pollution due to pollution are serious.

In order to solve this problem, Korean Utility Model Registration No. 306394 has proposed a breakwater with a water hole so that seawater can be circulated under the title of "breakwater structure for over-breaking and seawater exchange." The Utility Model Registration No. 306394 is provided with a front block and a body block having a plurality of sea water passages on a foundation stepped stone installed on the sea floor, and a cap concrete that protrudes above the sea surface to prevent overwaves is placed on the body block. It is done.

According to the above-described prior art, it is possible to keep the seawater in the inland sea clean by the inflow of seawater through the seawater canopy, it is possible to maintain a quiet state of the inner surface by blocking the blue waves through the cap concrete.

However, in the case of the breakwater as described above, the components for forming the breakwater structure is composed of a combination of a plurality of unit components (front block, body block, cap concrete, ..., etc.), the construction of the corresponding unit for each combination of unit components Since each construction process is required for the construction is not easy and there is a long disadvantage of air.

In addition, in the prior art, the capconcrete is provided with a cap concrete to block the moon wave in addition to the sea water flow function for introducing the seawater of the external sea into the inland sea, but the capconcrete simply blocks the inflow of seawater into the inland sea as a unit structure having a rectangular parallelepiped shape. When entering the blue wave due to the typhoon, there is a limit in its function, such as the lack of breakwater function.

The present invention is to solve the above-mentioned problems, excellent construction properties as a single structure, clean seawater of the open sea can be introduced into the inland sea through the circulation passage to prevent water pollution in the water, concave toward the open sea Through the round-jin guide surface and the circulating surface of the seawall extending above the guide surface, the seawater flowing from the open sea can be returned to the sea side for effective breakwater, and as a result, it is possible to It is an object of the present invention to provide an upright breakwater structure having seawater circulation and over-wave protection function that can be safely protected from waves.

In order to achieve the above object, the present invention, in the breakwater to be installed on the sea for the purpose of protecting the ships and facilities in the harbor, provided with a foundation floor of concrete material seated on the foundation stone installed on the bottom of the sea floor, A protective wall made of concrete for protection is integrally formed on the floor. The barrier has sidewalls on both sides thereof, and the inner sidewall of the sidewall is formed in a narrower width toward the top to induce the rise of waves on the inclined front surface. A curved guide surface is formed thereon, and barrier ribs are integrally formed on the guide surface between both sidewalls of the barrier wall so that a plurality of flow guide grooves are formed in front of the barrier wall by the barrier ribs. On the guide surface in the groove is formed a circulation passage penetrating the back of the barrier for seawater flow in and out, The upper end of the rear surface provides an upright breakwater structure having a seawater circulation and over-the-wave prevention function, characterized in that the seawater film having a circulating surface having the same curvature as the guide surface toward the sea side.

Here, the sea film is provided with a structure that the auxiliary film is stretchable from the sea film so that the height of the sea film can be changed according to the sea wave height, the auxiliary film is further provided along the longitudinal direction of the bottom of the sea buoy to the sea level Accordingly, the auxiliary membrane may be actively stretched from the sea membrane.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view of an upright breakwater structure having a seawater circulation and anti-webbing function according to the present invention, Figure 2 is a cross-sectional view taken along line A-A according to FIG.

As shown in the figure, the upright breakwater structure according to the present invention is a unitary foundation floor 20 and concrete foundation seated on the foundation stone 10 installed on the bottom of the seabed as a single structure, and the foundation floor 20 It is provided with a protective wall 22 of concrete material formed integrally for protection on the top.

The barrier wall 22 is a unitary structure and has side walls 220 integrated on both sides thereof. The cross-section of the barrier 22 inside the side wall 220 is narrowed toward the top as shown in FIG. 2, and the inclined surface of one side of the barrier wall is concave round toward the sea side as the width narrows. Face 222 is formed. The induction surface 222 induces a rise above the barrier when the waves pushed from the sea hit the barrier 22.

As shown in the figure, the barrier 22 may be continuously connected to each other through the tension bolt B in a state in which two or more barriers are continuously arranged such that the side walls face each other.

Subsequently, an upright bulkhead 224 having a predetermined thickness is integrally formed on the guide surface 222 between both sidewalls 220 of the barrier wall 22 with a uniform shoulder, and thus, the front of the barrier wall includes a plurality of flow guide grooves ( 226 is formed. Therefore, when the waves pushed from the sea hit the barrier, the flow of seawater is guided through each partition guide groove 226 through the partition 224 and the run-up is guided through the guide surface 222 to protect the barrier ( The impact load transferred to 22) can be minimized.

Furthermore, a circulation passage 228 penetrating the rear surface of the barrier wall 22 is formed in the guide surface 222 in each of the flow guide grooves 226. The circulation passage 228 is for the inflow and outflow of seawater from the outer sea to the inland sea or from the inland sea to the offshore sea, through which seawater can be circulated, thereby preventing water pollution of the inland sea due to the stagnation of seawater.

Furthermore, a seawater film 229 having a circulating surface of the same curvature as the guide surface 222 is integrally formed at the upper end of the rear surface of the barrier wall 22. The seawater barrier 229 prevents the seawater that has flowed through the induction surface 222 from being waved to the inland sea side, and flows the seawater back to the offshore side and keeps pushing it. It induces offset interference to reduce wave energy.

Preferably, the sea film 229 may be provided with an auxiliary film 229a having a structure that can be stretched from the sea film 229 so that the height of the sea film 229 can be changed according to the height of the sea. In this case, the height of the breakwater structure can be changed according to the sea wave height, and more effective breakwater can be expected.

More preferably, a buoyancy body 229b may be further provided at a lower end of the auxiliary film 229a along its longitudinal direction. In this case, the auxiliary film 229a can be actively stretched from the sea film 229 according to the sea level due to the buoyancy force by the buoyancy body 229b. Therefore, no additional manpower or other power is required for the expansion and contraction of the auxiliary membrane 229a, and a more effective response to the moon wave is possible. As the buoyancy body 229b, a general styrofoam or a hollow tube, which is lighter in specific gravity than water, is applied, or a general drum can be made of a hollow inside.

Looking at the operation and effect of the present invention with reference to Figure 3, according to the embodiment of the present invention as described above, clean seawater of the open sea (1) through the respective circulation passages 228 formed in the barrier wall 22 2) or contaminated seawater in inland sea (2) can freely flow into the sea (1). As a result, it is possible to prevent inland water due to stagnation of seawater, that is, anti-water pollution, and thus to solve aquatic ecological degradation and environmental pollution problems.

In addition, according to an embodiment of the present invention, when the seawater is pushed from the outer sea (1), the guide surface 222 formed on the curved surface rounded concave upward toward the outer sea (1), that is, the barrier 22 and the guide surface The runoff of the seawater is induced by the circulating surface of the seawater film 229 extending directly above, and the rushed seawater flows back to the sea side through the circulating surface. As a result, offset interference with the waves that are continuously being pushed is induced, thereby significantly reducing the wave energy imparted to the breakwater structure.

In addition, according to an embodiment of the present invention, while the auxiliary film 229a is elastically installed in the sea film 229 for inducing circulation, the auxiliary film 229a is provided by the buoyancy body 229b provided thereon. Active stretching is possible from the sea film 229 depending on the height. Therefore, even if the sea level is raised to some extent, the sea film can extend the height without a separate operation, it is possible to more effectively prevent the moon wave (越 波).

As described above, according to the upright breakwater structure having the present invention seawater circulation and over-the-wave prevention function, the clean seawater of the open sea can be introduced into the inland sea through the circulation passage to prevent water pollution in the sea, and concave toward the open sea. Thus, the rounded curved surface, that is, the guide surface and the circulating surface, effectively blocks the seawater flowing from the external sea and flows back to the sea side, so that the vessel and various water facilities in the harbor can be safely protected from the blue.

What has been described above is only one embodiment for carrying out the present invention, and the present invention is not limited to the above-described embodiment, and the present invention is made without departing from the gist of the present invention as claimed in the following claims. Anyone with ordinary knowledge in this field will have the technical spirit of the present invention to the extent that various modifications can be made.
