Fragile-supported sofa breakwater for soft ground and construction method thereof {BREAKWATER FOR REMOVING WAVE AND CONSTRUCTION METHOD FOR THE SAME}

The present invention relates to a pile support sofa breakwater for soft ground according to the present invention and a construction method thereof, and more particularly, by embedding a plurality of support piles along a seabed in a deep water depth area having a small incident wave height and having a deep soft layer. To reduce excessive expenses for the treatment of soft ground when designing and constructing port structures such as breakwaters or quay walls in soft ground,

Furthermore, by introducing a slit caisson composed of a bottom plate, a slit wall, and a reflective wall, the water surface eliminates the waves propagating from the outer sea side to the inland sea side, thereby increasing the sofa effect, thereby reducing the transmitted waves and reflected waves from the surface to the inland sea. Can and

In addition, by forming half-wave holes in the bottom plate of the slit caisson, the waves entering the running room formed by the slit walls can be flowed back to increase the effect of reducing the wave waves, thereby significantly reducing the height of the structure.

In addition, by introducing the sofa plate in the underwater part, the sofa effect by the sofa plate reduces the transmission wave and reflection wave from the underwater part to the inland sea, and at the same time, seawater exchange is performed in the open sea and the inland sea, which can greatly improve the water quality of the inland sea. We propose a pile support sofa breakwater for soft ground and its construction method.

In general, breakwaters, rafts, and quay wall structures in which large vessels are docked are divided into remnant type and gravity type according to the ground conditions.In the case of gravity type, caisson structure, which is a heavy object, is generalized, so that marine equipment such as large cranes The difficulty of the construction, such as to be secured is high, thereby significantly increasing the construction cost.

In particular, when designing and constructing breakwater, revetment, and quay wall structures in the deep-depth soft ground, the cost of handling the soft ground is much higher than the construction cost of concrete holes, and the overall construction cost is greatly increased, causing problems in the stability and functionality of the structure. Moreover, when taking a gravity type structure as mentioned above, the burden becomes further weighted.

Has a problem.

In addition, the diameter of the prior art 2 can improve the quality of the inland sea through the sofa effect and the seawater exchange between the sea and the offshore sea by placing a sofa plate between the piles,

In the water surface part of the bridge structure, the sofa board is directly hit with the blue wave. In this case, the blue wave is overwhelmed or overwhelmed, so the more active sofa effect cannot be expected. Therefore, it is not possible to increase the static temperature by reducing the wave transmission rate to the inland sea and lower the ceiling height. Exposing the limits.

And an upper plate 30 mounted on the slit wall 24 and the reflective wall 26 of the slit caisson 20.

1 to 4, in the soft ground pile supported sofa breakwater according to the present invention, the support pile 10 is

Since the incident wave height is small and the soft layer is deep, buried more than a predetermined depth along the sea bottom surface SB, the upper portion of the support pile 10 is connected to the bottom plate 22 of the slit caisson 20.

And the support pile 10 is arranged in a line on the outer sea (OS) and the inner sea (IS) side of the bottom plate 22, if necessary between the support pile 10 provided on both sides of the bottom plate (22) The support pile 10 is further provided to reinforce the supporting force of the structure.

In addition, the support pile is not shown in the accompanying drawings, but the reinforcement is reinforced reinforced concrete made of a pipe shape, and the inside is preformed into a hollow hollow,

In addition, it is preferable to apply prestressing during molding of the support pile so as to effectively cope with shear stress caused by live load due to seawater when the height is high due to slit caisson and upper plate connected to the upper part and typhoon or tsunami.

Therefore, the support pile 10 according to the present invention can reduce the excessive cost for the treatment of soft ground during the design and construction of port structures such as breakwaters and quay walls in large depth soft ground, and the conventional gravity type harbor structure It will be possible to improve the economics by shortening the cost and construction period required for the construction of the building.

The slit wall 24 is formed on the outer sea (OS) side of the bottom plate 22, a plurality of slits 24a are formed in the direction of gravity, if necessary slit of the slit wall, although not shown in the accompanying drawings Can be formed in a form perpendicular to the direction of gravity,

In addition, the reflective wall 26 is formed in the sea (IS) side of the bottom plate 22 is formed in the form that the slit 24a is not formed.

That is, in general, the surface layer of the seawater is high due to friction such as wind and the blue is strong, in this case, it is difficult to expect a full sofa effect in the surface of the seawater surface layer only by the sofa board according to the prior art 2

The blue wave propagated from the outer sea OS side to the inshore sea IS side by the slit caisson 20 according to the present invention is attenuated while passing through the slit 24a of the slit wall 24, thereby increasing the sofa effect near the water surface. As a result, the effect of reducing the propagation wave and the reflected wave toward the inshore sea (IS) side can be obtained, and the positive temperature of the sea (IS) can be increased.

In addition, in order to flow the seawater and / or blue water entered into the flowing water chamber 28 formed in the slit caisson 20 according to the present invention to the open sea (OS)

By forming a plurality of half-wave holes (22a) in the bottom plate 22 in a rectangular shape and returning the blue wave toward the open sea (OS), the effect of reducing the wave or wall is increased, so that the height of the fabric height of the structure, that is, the sea level is the highest. The height difference with the top of the breakwater can be greatly reduced.

The half-wave hole 22a may be formed in a circular or oval shape as well as a rectangular shape.

Accordingly, the top plate 30 is connected to the breakwater wall 33 that forms a guide surface 33a by a constant curvature or bend toward the outer sea OS, and is connected to the breakwater wall 33 to form a substantial portion of the top plate 30. It comprises a road surface 36 is constructed by concrete (C), asphalt or the like to occupy.

In addition, the railing portion 38 is formed on the road surface 36 to protrude upward from the inland sea IS side to prepare for a safety accident such as a vehicle or a user falling or falling.

That is, to prevent the ocean waves propagating from the outer sea (OS) side to the inner sea (IS) side through the induction surface (33a) of the blast wall 33 to the moon wave and / or overhang to the inner sea (IS) side, At the same time, the treated seawater is returned to the offshore (OS) side to induce offset interference with the blue waves that continue to be pushed to obtain a sofa effect to dissipate the blue.

As shown in FIG. 7 and FIG. 8, the top plate 30 has an alternative shape for more efficiently constructing the barrier wall 33 and the road surface 36 constituting the top plate 30 and maximizing the over-wave and sofa effects. This will be described in detail.

Furthermore, as shown in (a) and (b) of FIG. 8, a plurality of flowing holes 35a may be formed in the flowing plate 35, and the side of the offshore OS may be formed by the flowing holes 35a. After the waves propagated from the impact wave wall 33, the sea water remaining in the oil plate 35 flows out into the oil chamber 28 of the slit caisson 20 to enhance the sofa effect, and to reduce the effect of the wave or wall It can be maximized.

As shown in FIGS. 1 and 2 and 4 to 6, the sofa plate 40 according to the present invention is for reducing the propagation wave and the reflected wave due to the waves propagated from the outer sea OS side to the inshore sea IS side. Induces a sofa effect,

In addition, it is possible to prevent the deterioration of the water quality of the inland sea (IS) by exchanging seawater in the offshore sea (OS) and the inland sea (IS), so that the seawater flowing into the inland sea (IS) stays.

That is, as shown in FIG. 5, the sofa plate 40 is connected to the bottom surface of the bottom plate 22 of the slit caisson 20 and buried along the sea bottom SB, and is located between the support piles 10. Formed to

In this case, the sofa plate 40 is located between the support pile 10 located on both sides of the bottom plate 22 of the outer sea OS and the inner sea IS.
