Description

Coastal erosion prevention structure {Structure for preventing coastal erosion}

The present invention relates to a coastal erosion prevention structure, and provides a technique capable of effectively preventing coastal erosion by disposing triangular pyramid structures on the inner and outer sides to form a double triangular pyramid shape.

In recent years, abnormal climate changes due to global warming have frequently occurred, and as a result, Korea, which has three sides of the sea, is experiencing severe climate change even in the sea. Among them, coastal erosion caused by tidal waves, high waves, and rip currents is getting more and more serious.

In order to prevent such coastal erosion, many resources are being invested in the construction of breakwaters, but due to indiscriminate installation, the marine resources of the nearby coast are becoming more and more devastated, which leads to a decrease in fishermen's income.

In general, coastal erosion occurs locally due to meteorological conditions such as storms, or over a long period of time due to continuous wave energy and tidal difference.

In order to prevent such coastal erosion, various marine structures have been installed, and erosion of the coastline and the sandy beach has been prevented by stacking jets, tetrapods, and structures on the coast such as seawalls and breakwaters.

However, since the jetty whose top protrudes above the sea level is a structure in which tides and waves are concentrated on the coast at both ends of the jetty, the flow speed increases and the coast at both ends of the jetty is intensively eroded by strong wave energy. there is.

In addition, the inner coast of Dolje has a problem in that seawater exchange is not smooth and stagnant, which deteriorates water quality and hinders coastal scenery.

In addition, existing tetrapods (TTP) or structures installed so that the upper part of the structure is submerged below the sea level are not easy to move and transport and are structurally unstable, so seawater exchange is not smooth like a jetty, resulting in deterioration of water quality and marine life There is a problem that hinders coastal fishing activities because it is not settled.

Hereinafter, a structure for preventing coastal erosion according to the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIGS. 1 to 4, the coastal erosion prevention structure (hereinafter referred to as a structure) proposed by the present invention has a double triangular pyramid structure in which triangular pyramid structures are disposed on the inside and outside.

These structures include: an outer triangular pyramid (1) having an empty space formed therein and having a triangular pyramid shape; It is integrally disposed inside the outer triangular pyramid (1) and has a double structure of the inner triangular pyramid (2) having a triangular pyramid shape.

In more detail,

The outer triangular pyramid 1 includes first to third hypotenuses 6, 7, and 8; a first lower edge 9 connecting the lower ends of the first hypotenuse 6 and the second hypotenuse 7; a second base (10) connecting the lower ends of the second hypotenuse (7) and the third hypotenuse (8); It includes a third base 11 connecting the lower end of the third hypotenuse 8 and the first hypotenuse 6.

The first to third hypotenuses 6, 7, and 8 have a constant volume, thereby properly securing a contact area with seawater to prevent wave power from being transmitted. For example, the first to third hypotenuses 6, 7, and 8 have various cross-sectional shapes such as circular cross-sections, rectangular cross-sections, and polygonal cross-sections.

Further, the first to third bottom edges 9, 10, and 11 have a shape in which the middle portions 12, 13, and 14 are bent upward at a predetermined angle θ. The first to third base edges 9, 10, and 11 have a constant volume and have various cross-sectional shapes, such as circular cross-sections, square cross-sections, and polygonal cross-sections, for example.

An inner triangular pyramid 2 is disposed inside the outer triangular pyramid 1 to have a double triangular pyramid structure.

The inner triangular pyramid 2 has a pyramidal shape similar to the outer triangular pyramid 1, and is composed of fourth to sixth hypotenuses 3, 4, and 5.

The lower end of the fourth hypotenuse (3) is connected to the middle (12) of the first base (9), the lower end of the fifth hypotenuse (4) is connected to the middle (13) of the second base (10), and the sixth The lower end of the hypotenuse 5 is connected to the middle 14 of the third lower edge 11.

For example, the fourth to sixth hypotenuses 3, 4, and 5 have various cross-sectional shapes such as circular cross-sections, rectangular cross-sections, and polygonal cross-sections.

Such a structure is placed on the seashore to prevent coastal erosion, and is laminated in a structure as shown in FIG. 4 .

That is, it is a structure in which triangular structures are arranged in a row in a horizontal direction, and inverted triangular structures are stacked between the triangular structures.

A method for manufacturing such a structure is described in more detail as follows.

That is, the manufacturing method of the triangular pyramid structure includes the external triangular pyramid manufacturing step (S100); Internal triangular pyramid manufacturing step (S110); and positioning and combining the inner triangular pyramid 2 inside the outer triangular pyramid 1 (S120).

First, a step (S100) of manufacturing the outer triangular pyramid 1 proceeds.

As described above, the external triangular pyramid 1 is composed of the first to third hypotenuses 6, 7, and 8 and the first to third base edges 9, 10, and 11, and a formwork having the same shape is installed. do.

At this time, the formwork is installed so that the first to third base edges 9, 10, and 11 have a shape bent upward at a certain angle θ from the ground.

In this way, after installing the triangular pyramid-shaped formwork, concrete is poured, and cured for a certain period of time to manufacture.

The internal triangular pyramid manufacturing step (S110) proceeds similarly, and the internal triangular pyramid 2 forms a triangular pyramid shape composed of the fourth to sixth hypotenuses 3, 4, and 5, and the formwork is installed in the same shape. .

In addition, the inner triangular pyramid 2 is manufactured by pouring concrete into the formwork and then curing it.

After the outer triangular pyramid 1 and the inner triangular pyramid 2 are manufactured in this way, the inner triangular pyramid 2 is inserted into the outer triangular pyramid 1 and connected (S120).

That is, in a state where the inner triangular pyramid 2 is positioned on the ground, the outer triangular pyramid 1 is lowered from the upper side using a crane or the like to be positioned outside the inner triangular pyramid 2.

Then, by finely lifting the inner triangular pyramid 2, the lower ends of the fourth to sixth hypotenuses 3, 4, and 5 are aligned with the middle portions 12, 13, and 14 of the first to third base edges 9, 10, and 11. place on

In this state, concrete is additionally applied to the point where the lower end of the fourth to sixth hypotenuses (3,4,5) and the middle (12,13,14) of the first to third hypotenuses (9,10,11) are connected. It is connected by pouring or by weaving rebar.

Of course, the manufacturing method of the present structure is not limited to this method and can be manufactured by changing other ways.

For example, after installing a formwork in a double structure in which the inner triangular pyramid 2 is disposed inside the outer triangular pyramid 1, it may be manufactured by pouring and curing concrete.
