Abstract

The present invention relates to a wave dissipation block and a method of constructing a seawater exchange breakwater which dissipate a wave of the open sea, prevent wave overtopping, and use seawater circulation holes formed by a plurality of concave grooves formed on a front surface and a side surface to allow seawater of the open sea to enter inland sea to maintain tranquility of the inland sea and promote stability of a ship. The method of constructing a breakwater divides the open sea and inland sea to dissipate a wave and promote safety of the inland sea, and comprises: a step of installing container blocks in two rows to bring rear surfaces into contact with an upper portion of a foundation riprap; a step of stacking third blocks of claim 1 on upper portions of the container blocks; a step of stacking second blocks of claim 1 in two rows to bring rear surfaces into contact with upper portions of the third blocks, and forming a wave chamber between blocks on a side; a step of stacking first blocks of claim 1 in two rows to bring rear surfaces into contact with upper portions of the second blocks, and forming a wave chamber between blocks on a side; and a step of forming cap concrete on upper portions of the first blocks. The present invention allows clean seawater entering from the open sea to enter an inner harbor through a breakwater to eliminate waves or rapids of the open sea in the inland sea. Water holes and wave chambers are formed to have a wave dissipation function and a fishing bank function and secure structurally stable strength.

Description

[0001] The present invention relates to a wave block construction method and a wave breaking block construction method using the same,

[0001] The present invention relates to a block-type sea water exchange breakwater, and more particularly, to a block-type sea water exchange breakwater, more particularly, to a seawater exchange breakwater having a sea water circulation hole formed by a plurality of concave grooves formed on the front surface and side surface, So as to maintain the constant temperature of the inland waters and to stabilize the ship, and an invention relating to a construction method of a seawater exchange breakwater construction method.

The breakwater, which is the basic facility of the harbor, is a facility that keeps the inland waters from being cluttered with waves from the outer sea and keeps the inland waters cool. However, There is a problem that seawater enters the sea and the seawater in the harbor enters the inland and there is a shortage of circulating water.

In general, the types of breakwaters are mostly used as upright, inclined, and hybrid types. Especially, the soap block such as TTP is used as the covering material of the sloping breakwaters, but the situation such as local conditions and various supply and demand conditions May be used to select an upright structure such as a caisson.

However, existing breakwaters have disadvantages in terms of economics because the sofa is not easy, the block making is complicated, and the reinforcing bars are inserted. In addition, But very limited.

In addition, it is a simple concrete structure, which is not friendly to nature and thus can not provide the hydrophilic property to visitors.

Hereinafter, a method for constructing a breakwater using the first, second, and third blocks 100, 200, and 300 will be described with reference to FIGS. 10 to 12. FIG.

To this end, a barrel block 410 having an inclined surface is formed on the upper surface of the foundation stone 400, and the rear surfaces of the barrel blocks 410 are stacked so as to be in contact with each other. It is preferable that the clay stone 420 is reinforced in the front toe (TOE) portion of the barrel block 410.

The third block 300 is stacked on the top surface of the block block 410 so that the side end of the third block 300 is stacked on the top surface of the block block 410, So as to be stacked upside down so as to improve the rigidity. A hexagonal water flow chamber is formed between the side surfaces of the third block 300 and the third block 300, which are in contact with each other, while the third side flow passages 320 on both sides are in contact with each other.

The second block 200 may be stacked on the upper portion of the third block 300 in one row or a plurality of rows in two rows so that the rear surfaces thereof are in contact with each other. At this time, the upper and lower blocks are stacked so that the side ends of the second block 200 are located in the middle of the upper surface of the third block 300, thereby improving the robustness. A hexagonal water flow chamber is formed between the side surfaces of the second block 200 and the second block 200 which are in contact with each other.

Also, it is preferable that the first block 100 is stacked in two rows on the upper surface of the second block 200, and similarly, the rear surfaces are stacked so as to be in contact with each other. At this time, the upper and lower blocks are stacked so that the side ends of the first block 100 are located in the middle of the upper surface of the second block 200, thereby improving the rigidity. A hexagonal water flow chamber is formed between the side surfaces of the second block 200 and the second block 200 which are in contact with each other. The cap concrete 500 may be constructed on the upper surface of the first block 100.

That is, since the blocks 100, 200, and 300 are in contact with each other and are laminated on the upper and lower sides, the grooves and the front protrusions formed in a trapezoidal shape are used to express patterns of a certain shape, To provide a visually comfortable structure. In addition, the side surfaces between the blocks 100, 200, and 300 may be in contact with each other to provide a function of a water chamber and a fish tank in which a wave flows.

The ropes may be connected to the first, second, and third side concave grooves 130 formed on the side surfaces of the blocks 100, 200, and 300 using a crane or the like to move the blocks 100, 200, The first, second, and third bottom concave grooves 150, 250, and 350 formed on the bottom surfaces of the first and second floor panels 230 and 330.

On the other hand, when the size of the breakwater increases and the width needs to be enlarged, as shown in FIG. 12, the rear surface of the block 410 is spaced apart at a predetermined interval, The width of the breakwater may be enlarged by making a space at a predetermined distance so as not to directly contact the backside between the blocks 100, 200 and 300, .

Therefore, in the breakwater according to the embodiment of the present invention constructed as described above, a large wave generated in the outer sea hits the blocks 100, 200, and 300, 200, and 300 through the drainage grooves that are formed on the inner surface of the block 100, so that the forces are weakened and discharged to the inner water side.
