Description

FLOATING PIER WITH A DEVICE FOR REDUCING AMOUNT OF SWAY AND CONTROLLING BUOYANCY}

The present invention relates to a floating pier, and more specifically, when a slope occurs due to an offset load on the floating pier, the floating pier is capable of adjusting the buoyancy of the floating pier so that the floating pier can be restored horizontally. About.

A floating pier is a facility that floats on the water using buoyancy, and is installed to provide a berthing facility for small ships, a water fishing facility, or a passage for people's movement or cargo, in a water body such as an inland lake, river or coastal sea area. It means the structure that becomes.

In the past, it was common to construct a buoyancy base by weaving a buoyancy material such as logs or styrofoam into a certain shape, and then install a footboard through which people can move on the upper surface of the buoyancy base.

However, in the case of using a buoyant material that is vulnerable to impacts such as logs and straw foam, the life and safety of the floating pier is reduced as the buoyant material is easily damaged by waves or external impacts, and the ocean is contaminated by the broken pier. There was a problem that considerable manpower was consumed in the installation and recovery of the sub-pier.

In order to improve the above problems, sub-piers made of concrete, PE, and steel have recently been developed. As materials with excellent corrosion resistance, mechanical strength, and recyclability are used, the risk of breakage of sub-piers due to an instantaneous external impact has decreased compared to the past, but due to the characteristics of sub-piers that are affected by external forces in various marine environments, it is still resistant to continuous loads. There is a problem of instability.

For example, in the case of sea waves, loading and unloading of marine products, when passengers are boarding or disembarking, an uneven load may be generated on the sub-pier, and in particular, external forces (crowd load, loading) that are continuously applied at a time difference. Load, etc.), an offset load is generated on the sub-pier, resulting in a superelevation, which may cause the sub-pier to overturn or lateral swing, and there is a risk of personal injury.

In order to prevent the side piers from losing the level or oscillating due to the bias load generated on the floating piers, a restoration-related technology is required to maintain the level of the floating piers.The buoyancy of the floating piers can be adjusted so that the inclined piers can be restored horizontally. However, it is necessary to develop a pier.

FIG. 2 is an enlarged view of a device for reducing fluctuation and controlling buoyancy in a sub-pier with a device for reducing fluctuation and controlling buoyancy according to another embodiment of the present invention, and FIG. It is a view showing a cross-section of a sub-pier with a device for reducing the amount of shaking and controlling the buoyancy according to.

2 and 3, the shaking amount reduction and buoyancy control device 200 as another embodiment of the present invention includes a receiving part 300 into which the buoyancy control part 320 is inserted through an open lower part. It further includes, and air may be filled in the sealed first buoyancy layer 310 formed in the receiving part 300. That is, the agitation amount reduction and buoyancy control device 200 includes a case-shaped accommodation unit 300 having an open lower portion, and a buoyancy control unit having a second buoyancy layer 400 and a third buoyancy layer 500 formed therein. It may include (320).

According to another embodiment, the shaking amount reduction and buoyancy control device 200 including the receiving part 300 may be coupled to the lower part of the upper plate 120.

Unlike FIG. 1, which shows an embodiment in which the receiving part 300 is not included, there is a difference in that another embodiment including the receiving part 300 is shown in FIGS. 2 and 3.

It goes without saying that the accommodation part 300 is a space into which the buoyancy control part 320 is inserted, and the shape of the accommodation part 300 may be different depending on the shape of the buoyancy control part 320.

As shown in FIG. 2, the receiving part 300 serves to generate buoyancy by filling air in the sealed first buoyancy layer 310 formed as the buoyancy control part 320 is inserted through the open lower part.

Specifically, the receiving unit 300 is to form a first buoyancy layer 310, which is a space sealed by the second separation membrane 240, which is an inner surface of the receiving unit 300 and an upper surface of the buoyancy control unit 320. And air can be filled in the space.

Depending on the height of the buoyancy control unit 320 inserted into the receiving unit 300, the volume to be filled with air in the first buoyancy layer 310 may be different, and as the volume increases, the amount of buoyancy generated increases. Thus, the function of the first buoyancy layer 310 as a buoyancy material will be increased.

In this case, the buoyancy control unit 320 is divided by a second buoyancy layer 400 in a sealed form in which air is accommodated, and the second buoyancy layer 400 and the first separation membrane 230 and the second It may include a third buoyancy layer 500 disposed at the bottom of the buoyancy layer 400 and having an open bottom portion.

That is, the buoyancy control unit 320 is inserted through the lower portion of the receiving unit 300, and generates buoyancy by accommodating air in the second buoyancy layer 400, and air and water in the third buoyancy layer 500. It receives and generates buoyancy and at the same time plays the role of regulating buoyancy.

The buoyancy control unit 320 is the water contained in the third buoyancy layer 500 by the pressure difference between the internal pressure, that is, the air pressure accommodated in the third buoyancy layer 500 and the atmospheric pressure outside the buoyancy module 100 And an air moving unit 210 that serves to adjust the amount of air, and connects the inside of the buoyancy control unit 320 and the outside of the buoyancy module 100 for the above adjustment.

The air moving part 210 passes through the first separation membrane 230 and the second separation membrane 240, and crosses the first buoyancy layer 310 and the second buoyancy layer 400, and the third buoyancy layer 500 ) It serves to connect the inside and the outside of the receiving part 300.

The air moving unit 210 further includes an opening/closing unit 220 that is opened and closed by a pressure difference between the internal pressure of the buoyancy control unit 320 and the atmospheric pressure, and through the air moving unit 210 and the opening/closing unit 220, By discharging and introducing air contained in the third buoyancy layer 500, the amount of water and air contained in the third buoyancy layer 500 is adjusted to adjust the buoyancy.

One side of the air moving unit 210 is directed toward the inside of the buoyancy control unit 320, and the other side is disposed toward the outside of the buoyancy module 100, and the other side of the air moving unit 210 is near the buoyancy pipe 110. It can be located on the surface of the water, and if it is arranged to be connected to the outside (air) so that it is not submerged in water, it can be placed in any position.

The principle in which air is moved through the air moving unit 210 due to the pressure difference between the internal pressure of the third buoyancy layer 500 and the atmospheric pressure, that is, the principle that the buoyancy control unit 320 controls the buoyancy is described in detail in FIG. 4. Let me explain.

4 is a view illustrating a principle of a buoyancy control unit in a sub-pier with a device for reducing agitation and controlling buoyancy according to another embodiment of the present invention.

First, (a) of FIG. 4 shows a state in which the buoyancy control unit 320 is floating on the water, and the second buoyancy layer 400 is filled with air, and the third buoyancy layer 500 is filled with air and water. Is in a state.

The height of the water filled in the third buoyancy layer 500 is the same as the height of the water filled around the buoyancy control unit 320. 4(a) is a general state without external impact, the atmospheric pressure and the pressure of the air inside the third buoyancy layer 500 are the same, and the opening/closing part 220 is closed.

4B is a view showing a state in which the buoyancy control unit 320 is raised by various external impacts such as swells.

An instantaneously rising force is applied to the buoyancy control unit 320, and accordingly, the opening/closing unit 220 receives a force in a direction opposite to the rising force, that is, in a downward direction, The opening/closing part 220 is maintained in a closed state. At this time, the third buoyancy layer 500 is temporarily filled with water equal to the height of the surrounding water, as shown in FIG. 4(a), and at this time, the third buoyancy layer 500 is filled with water. This unfilled space becomes a vacuum.

When the buoyancy control unit 320 is raised, momentarily, after passing through the state of FIG. 4(b), it becomes the state of FIG. 4(c). Water is filled in the space in the vacuum state of the third buoyancy layer 500. The vacuum portion of the third buoyancy layer 500 is eliminated by the water column formed in the third buoyancy layer 500, whereby the pressure of the inside and outside atmospheric pressure of the third buoyancy layer 500 is the same.

The weight of the buoyancy control unit 320 increases as the water column is filled, and since the opening and closing unit 220 is closed, the water column formed in the third buoyancy layer 500 becomes the weight of the buoyancy control unit 320 completely. Because.

By the water column serving as a weight, the buoyancy control unit 320 descends by the corresponding weight, and as it descends, the water column formed in the third buoyancy layer 500 disappears, and a state as shown in FIG. 4(d) is do. That is, as shown in FIG. 4(a), the height of the water inside the third buoyancy layer 500 becomes the same as the height of the water around the buoyancy control unit 320, and the first buoyancy control unit 320 is located. It will be restored to the same state where it was.

As a technology for restoring balance by using a water column momentarily formed in the buoyancy control unit 320 when superelevation occurs, the water column formed by the pressure difference between the inside of the third buoyancy layer 500 and the atmospheric pressure acts as a spring for reducing motion.

As shown in Figure 4, in the buoyancy control-type steel sub-pier 10 of the present invention, the buoyancy control unit 320 is by a pressure difference between the internal pressure and atmospheric pressure of the third buoyancy layer 500, the third buoyancy layer ( By including an air moving unit 210 that enables the movement of water and air accommodated in 500) and an opening/closing unit 220 that opens and closes according to a pressure difference, when the buoyancy control unit 320 rises, the third buoyancy layer ( It is characterized in that by increasing the amount of water accommodated in 500), so as to descend by the weight of the received water, and to restore the buoyancy control unit 320 to its original position.

This does not simply generate buoyancy, but is different from existing buoyancy bodies that only generate buoyancy in that the object is restored to its original position and original height by controlling the pressure using the movement of water.

5 is a view illustrating a principle in which a buoyancy module is restored to a horizontal state in a sub-pier with a device for reducing agitation and adjusting buoyancy according to another embodiment of the present invention.

As another embodiment of the present invention, as a view showing a cross-section of the buoyancy control-type steel sub-bridge 10, the buoyancy module 100 cross-section has two sway reduction and buoyancy control devices 200 are arranged, buoyancy One side of the module 100 ascends and the other side descends, where superelevation occurs, and FIG. 5D is shown to recover horizontally through FIGS. 5A to 5B and 5C.

First, Figure 5a is a buoyancy module 100 in which superelevation has occurred, and the shaking amount reduction and buoyancy control device 200 disposed on the rising side is a third in a state in which the opening/closing unit 220 is closed, as shown in FIG. The buoyancy layer 500 is filled with air and water. Since the height of the water filled in the third buoyancy layer 500 is the same as the height of the water around the buoyancy module 100, the water is filled in the same way as the surrounding water inclined, and the other spaces are filled with air.

At this time, as outside air is blocked in the third buoyancy layer 500, the corresponding space momentarily becomes a vacuum of Torricelli.

The momentarily descending force is applied to the agitation reduction and buoyancy control device 200 disposed on the descending side, and accordingly, the third buoyancy layer 500 filled with air and water is filled with water. As water is filled, the internal pressure of the third buoyancy layer 500 increases, and the air in the third buoyancy layer 500 moves to the outside along the air moving part 210. That is, as air is moved from the inside of the third buoyancy layer 500 in a pressure state higher than atmospheric pressure to the outside due to a pressure difference, the opening/closing unit 220 is opened, and air is discharged.

5B is a view showing a state in which water is instantaneously filled in the agitation amount reduction and buoyancy control device 200 disposed on the rising side in a state where superelevation occurs. Although not shown in FIG. 5, the third buoyancy layer 500 is momentarily in a vacuum state as described in FIG. 4(b) and above, and then the space in the vacuum state of the third buoyancy layer 500 as shown in FIG. 5B. Water fills up.

In the apparatus 200 for reducing the amount of shaking and adjusting the buoyancy disposed on the lower side, the opening and closing unit 220 is in an open state, and the air in the third buoyancy layer 500 can be freely moved through the air moving unit 210 .

5C shows a state in which a water column is formed in the agitation amount reduction and buoyancy control device 200 disposed on the rising side, and as the water column is filled to increase the weight, the left part of the raised buoyancy module 100 Falls down. In other words, the water column acts like a water tank.

The buoyancy module 100 on the right, which has been lowered, rises relatively as the buoyancy module 100 on the left is lowered, so that the buoyancy module 100 itself becomes horizontal. The left shaking amount reduction and buoyancy control device 200 is in a state in which air is freely moved through the opening/closing unit 220, so there is no other limitation.

5D is a diagram showing the buoyancy module 100 that has recovered the horizontality, and each of the arranged vibration reduction and buoyancy control devices 200 is in a state in which the opening and closing portion 220 is closed, and the third buoyancy layer 500 is The filled water and the water around the buoyancy module 100 have the same height, and the balance is maintained.

As confirmed in Figure 5, in the buoyancy control-type steel sub-bridge 10 of the present invention, the buoyancy module 100 is convenient to the buoyancy module 100 by including one or more sway amount reduction and buoyancy control device 200 When superelevation occurs due to the inclination, each sway amount reduction and buoyancy control device 200 arranged in the buoyancy module 100 is characterized in that the steel sub-bridge is restored horizontally by using the principle to be restored to its original position. .

In addition, a receiving portion 300 filled with constant air is formed at the upper end of the sway amount reduction and buoyancy control device 200, regardless of the buoyancy control of the buoyancy control unit 320, reducing the amount of sway and It is characterized in that the buoyancy of a certain amount or more is acting on the sub-pier 10 provided with the buoyancy control device.

As described above, according to the sub-pier with the device for reducing the amount of fluctuation and controlling the buoyancy proposed in the present invention, the device for reducing the amount of fluctuation and adjusting the buoyancy is water and water accommodated therein by a pressure difference between the air pressure and atmospheric pressure received therein. By including a buoyancy control unit that adjusts the amount of air, when the amount of agitation is reduced and the buoyancy control device rises, the amount of water accommodated inside is increased, so that the amount of agitation and the buoyancy control device descends by the weight of the received water. The fluctuation reduction and buoyancy control device can be restored to its original position. In addition, by including a receiving portion filled with air in the sealed first buoyancy layer formed while the buoyancy control unit is inserted through the open lower portion of the buoyancy control unit and reduces the amount of fluctuation, generating buoyancy from the air accommodated in the buoyancy control unit In addition, by simultaneously receiving constant air in the receiving part to generate additional buoyancy, it is not affected by the buoyancy control by controlling the amount of water in the buoyancy control part, and the receiving part itself generates buoyancy separately to the buoyancy module. I can make it. In addition, the buoyancy module includes one or more sway amount reduction and buoyancy control devices, so that when superelevation occurs in the sub-piers due to an unbalanced load, the principle of reducing the amount of sway and restoring the buoyancy control devices arranged on the sub-piers to their original position. Using, the sub-pier can be restored horizontally.
