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

The floating structure 1 capable of responding to the flood level according to the present invention is constructed as a container terminal installed on the riverside, and has a base 10 constructed on the riverside as shown in FIG. 2.

The base 10 is made of a reinforced concrete structure, cut the river side, and forms a large concrete structure, the base 10 forms a lower surface (12a) of a predetermined size, of the base lower surface 12a Both sidewalls 12b are formed on the upper side, and the rear wall 12c is formed on the upper side of the base lower surface 12a so as to connect the rear side of the sidewall 12b.

The rear wall 12c of the base 10 forms a recess 12c 'on the wall surface, such recess 12c' is the rear surface of the main body 20 and the base 10 described later. Excessive frictional resistance is prevented from occurring between the rear walls 12c of the " That is, the concave portion 12c 'allows the main body portion 20 to greatly reduce the area where the rear surface contacts the rear wall 12c of the base 10, which is advantageous when the main body portion 20 moves up and down.

Accordingly, the base 10 has a cross-sectional structure having a “⊃” shape in which both sidewalls 12b and the rear wall 12c are connected to each other, and thus have a space portion 15 of a predetermined size. In the inner space portion 15 of the main body portion 20 to be described later is disposed in a size corresponding to the space portion 15.

The main body 20 is composed of a concrete structure in the space 15 of the base 10, and has a hollow structure having a floating space 22 formed therein, so that the total volume thereof is lighter than the specific gravity of water. .

Therefore, when exposed to the water level of the river side receives a buoyancy (floating force) according to the water level of the river, the floating space 22 is provided with a degree function that prevents water from penetrating through the body portion 20 from the outside have.

And the main body 20 is equipped with crane 315 facilities on the upper portion, the floating space 22 formed inside the main body 20 is large enough buoyancy generated by the floating space 22 It is large enough to support all the loads of the cargo 322 conveyed by the crane 315 facility of the upper part of the main-body part 20, and the crane 315, and to float on water.

As described above, when the main body 20 located in the inner space 15 of the base 10 is exposed to the water level of the riverside, the main body 20 floats from the inside of the base 10 to the upper side. In the case of moving by the guide portion 30 is provided so that the movement direction is limited only in the vertical direction.

As illustrated in FIG. 3A, the guide part 30 may include concave grooves 32a formed at both sides of the base 10 and both sidewalls of the main body 20 to correspond to the concave grooves 32a. And a convex protrusion 32b protruding from the 12b, and when the convex protrusion 32b is positioned in conformity with the shape of the concave groove 32a, the main body 20 is buoyant in the base 10. By the movement in the up and down direction is made so that the movement in the front and rear direction of the base 10 is limited.

In addition, as shown in FIG. 3B, the guide part 30 includes a convex protrusion 36a formed at both sides of the base 10 and a portion of the main body 20 to correspond to the convex protrusion 36a. And a concave groove portion 36b formed on both sidewalls 12b. The convex protrusion portion 36a and the concave groove portion 36b are adapted to each other so that the main body portion 20 is provided with buoyancy force in the base 10. By this, the movement in the up and down direction is made, and the movement in the front and rear directions is limited.

And the base 10 has a sweeping portion 50 to form a plurality of trenches (52) inclined forward on the lower surface thereof to discharge the dirt collected to the lower side of the main body portion 20 to the outside do. As the cleaning part 50 is shown in detail in FIG. 2, a plurality of trenches 52 are formed in the grooves at regular intervals, and the trench bottom surface 52a is forward from the rear of the base 10. It is inclined toward the structure.

Such cleaning part 50 is naturally discharged to the front of the base 10 through the inclined grooves provided in the trench 52 when floating or foreign matter flows and accumulates on the base lower surface 12a. . Therefore, a separate cleaning operation is not necessary, but if the sediment is deposited and the groove of the trench 52 is blocked, it can be easily cleaned by scraping it toward the base 10 by manual operation. In this case, the inclined groove groove structure of the trench 52 facilitates the sweeping operation.

In addition, the floating structure (1) corresponding to the flood level according to the present invention further comprises a water level control device (60) for adjusting the buoyancy by filling the floating space 22 of the body portion 20, the water level The adjusting device 60 has a structure having a pumping device 62 and a piping system 64 on the upper side of the main body 20. That is, the water level control device 60 is connected to the piping system 64 leading to the floating space 22 of the main body 20, and the pumping device 62 connected to the piping system 64 as shown in FIG. The pumping device 62 includes a water supply pump for supplying water to the floating space 22 and a water discharge pump for discharging water from the floating space 22.

Therefore, through the selective operation of such a water supply pump or water discharge pump it is possible to adjust the amount of water filled in the floating space 22, accordingly the magnitude of the buoyancy provided by the floating space 22 of the body portion Control can be achieved.

As shown in FIG. 4, the floating structure 1 capable of responding to the flood level according to the present invention operates as the main body 20 moves up and down according to the level of the river. The present invention operates in a state in which the buoyancy control of the main body 20 is made in accordance with the normal water level (ho) shown as a dashed line as usual, such a main body 20 is mounted on the base lower surface 12a and is supported. On the main body 20, a crane 315 facility is installed to perform the operation of loading or unloading the cargo 322 on the ship 320.

In this state, when the water level of the riverside becomes high, the main body 20 receives buoyancy due to the floating space 22 therein, and the buoyancy increased according to the water level causes the main body 20 to form the inner space of the base 10. Push it up. Accordingly, the main body 20 is moved upward by the guide part 30, and the main body 20 is the base 10 through the concave groove part 32a and the convex protrusion part 32b of the guide part 30. It moves stably to the top without protruding to the front side of the

In this case, since the buoyancy increases in proportion to the level of the riverside, the height of the main body 20 is adjusted in proportion to the level of the riverside. Therefore, the crane 315 located in the main body 20 is also simultaneously lifted so that the interval therebetween is kept constant in accordance with the elevated position of the ship 320 that shipped the cargo 322.

On the other hand, when the water level of the river side is lowered from the state in which the water level of the river side is increased in this way, the buoyancy applied to the main body 20 is reduced in contrast to the above, and as a result, the main body 20 is the inside of the base 10. Lowering the level of the crane 315 is also lowered, even when the body portion 20 is lowered through the guide portion 30 formed between the base 10 and the body portion 20 is safely and linearly lowered When the water level of the riverside reaches the smooth water level ho, the main body 20 rests on the base lower surface 12a.

When the water level reaches the low water level h2 where the level of the riverside is lowered from the flat water level (ho) of the riverside, the intensity of buoyancy applied to the main body 20 from the level of the riverside becomes smaller. The part 20 does not descend even further since it is seated on the base 10.

Therefore, the water level of the vessel 320 floating in the river is kept low in the low water level (h2), but the crane 315 of the main body portion 20 stays at the flat water level (ho), so that the crane 315 and the ship cargo 322 There is a slight height difference. However, the height difference between the crane 315 and the ship cargo 322 is significantly less than the height difference between the height of the ship cargo 322 of the crane 315 and the low water level (h2) in the conventional container terminal.

Therefore, the present invention can perform the crane 315 operation while maintaining a less height difference between the crane 315 and the ship cargo 322 than the conventional structure.

Meanwhile, in the present invention, the position of the main body 20 seated on the base 10 is adjusted according to the flat water level (ho), but the present invention is not limited thereto. According to the present invention, the position of the main body 20 seated on the base 10 may be set in accordance with the river water level of the low water level h2. In this case, in the normal ground water level (ho), the main body 20 is maintained in a state of being raised from the lower surface of the base 10 by buoyancy to a certain height, and the work is performed, and the level of the riverside is lowered to the low water level (h2). When it is lost, the main body 20 sinks inside the base 10 and is kept in a state seated on the base lower surface 12a.

Therefore, the crane 315 on the main body 20 can operate the crane 315 while maintaining its height at a constant height with respect to the cargo 322 of the ship 320 between the smooth water level ho and the low water level h2. Do.

On the contrary, if the riverside is maintained at the flood level h1, the main body 20 is further raised in accordance with the flood level h1. In this case, the crane 315 on the main body 20 has the height of the flood level h1. ), And the crane 315 can be operated while maintaining a certain height with respect to the cargo 322 of the ship 320 located on the flood level h1 of the river side.

Hereinafter will be described step by step with reference to Figure 5 with respect to the construction method 200 of the floating structure capable of responding to the flood level according to the present invention.

Floating structure construction method 200 that can respond to the flood level according to the present invention is first made of a step 210 to build a base lower surface (12a) in the concrete on the river side, such step (210) to the river side to a certain size It cuts and builds the base lower surface 12a using reinforced concrete.

In this case, the base lower surface 12a is formed with a plurality of trenches 52 inclined forward to form a sweeping portion 50. Such sweeping portions 50 each have an inclined groove. Forming the formwork and pouring concrete to form a trench (52).

The base bottom surface 12a thus formed is then constructed with concrete to construct both sidewalls 12b and rear wall 12c to the upper side. The step 220 of constructing both of the side walls 12b and the rear wall 12c from the concrete may include both side walls 12b in which concave grooves 32a are formed, respectively, from the base lower surface 12a to the upper side thereof. The rear wall 12c, which connects the rear side of the side wall 12b to each other, is concrete-constructed so that the space portion 15 having a “⊃” shaped cross section is formed on the upper side of the base lower surface 12a.

In addition, according to the present invention, after the two side walls 12b and the rear wall 12c of the base 10 are constructed of concrete, the main body 20 having buoyancy in the space 15 of the base 10 is concrete. The step 230 of building is made.

As such, the step 230 of constructing the main body 20 includes a main body having a size corresponding to the space 15 formed by the side walls 12b and the rear wall 12c on the upper surface of the base 10. The concrete body 20 is constructed such that the main body 20 has buoyancy through the inner floating space 22, and on both sides, concave grooves 32a formed on both sidewalls 12b of the base 10. Concrete is constructed in a structure that forms convex protrusions 32b that engage with each other.

Therefore, the main body portion 20 is engaged with the concave groove portion 32a formed on both side walls 12b of the base 10 by the convex protrusion portions 32b on both sides thereof, so that the main body portion 20 moves up and down without moving back and forth. It serves as a guide unit 30 to guide the descending.

In addition, in the step 230 of constructing the main body 20, the size of the floating space 22 disposed inside the main body 20 is sufficiently large, which means that the main body 20 is located at the level of the river. When exposed, the buoyancy force received by the body portion 20 is large enough to withstand the overall load of the crane 315 facility installed on top of the body portion 20 and the cargo 322 transported by the crane 315. Is formed.

Meanwhile, in the step 230 of constructing the main body 20, convex protrusions 32b may be formed on both sides instead of the concave groove 32a, and if both sidewalls 12b of the base 10 are formed, If the convex protrusions 32b are formed on both sidewalls 12b instead of the concave grooves 32a in the step 220 of building concrete, the base 20 in the step 230 of building concrete. Concave groove portions 32a corresponding to the convex protrusion portions 32b of 10 are formed on both side surfaces of the main body portion 20.

Therefore, through such a structure, the main body 20 is guided up and down in the space 15 of the base 10 without moving in the front and rear directions.

In addition, the present invention includes the step of adjusting the buoyancy by filling the water in the floating space 22 of the main body portion 20, in the buoyancy control step such that the body portion 20 in accordance with the smooth water level (ho) of the river side Buoyancy control is to be seated on the base (10).

In this case, the present invention uses the water level adjusting device 60 provided on the upper side of the main body 20. The water level adjusting device 60 is the upper portion of the main body 20, as shown in FIG. By adjusting the amount of water filled in the floating space 22 through a water supply pump provided on the side, it is to adjust the amount of buoyancy provided by the floating space 22 of the main body 20.

And while the buoyancy control of the main body 20 is made in this way, water of the river side is supplied to the main body 20 side so that the main body 20 receives the buoyancy.

As described above, according to the present invention, the main body 20 used as the berthing facility on the river side is movable up and down using buoyancy according to the level of the river side due to the internal floating space 22. Therefore, the crane 315 installed on the upper side of the main body 20 can always maintain a constant height with the docked ship, so it is very convenient to use the crane 315 for loading and unloading the cargo 322 on the ship 320. Done.
