FIG. 2 is a view showing a state in which the water cushion 400 closes the bottom of the downstream part 20 in FIG. 1 . 3 is a view showing a state in which water is accommodated in FIG. 2 .

1 to 3, the four-way dam including an openable and openable water cushion 400 according to an embodiment of the present invention, the dam body 100, the dam shoulder 200, the waterway (A), the side wall, the water cushion (400).

The dam body 100 is positioned between the upstream part 10 and the downstream part 20 . In other words, the upstream part 10 and the downstream part 20 may be separately formed by the dam body 100 .

The upstream part 10 is located relatively upward in an area (eg, a mountain) where the dam is installed, and the downstream part 20 is located below the upstream part 10 . When water flows, the water flows from the upstream part 10 to the downstream part 20 , overflows or passes through the dam body 100 to reach the downstream part 20 .

The dam shoulder 200 is formed in a pair on both sides of the dam body 100 , and may have a shape that soars upward from the dam body 100 . The dam shoulder 200 may prevent the water passing through the dam body 100 from moving to the outside. The dam shoulder 200 may include a shape in which the cross-sectional area becomes smaller as it goes upward.

The upstream part 10 , the downstream part 20 , the dam body 100 , and the dam shoulder 200 may all be formed on the foundation floor (B). The foundation floor (B) is first formed on the ground of the area where the dam is installed, and the structures of the dam may be installed thereon.

Dam body 100, each dam shoulder 200 is a geo-foam (geo-foam); And it may include a geogrid (geo-grid) and a concrete composite to be poured based on the geoform. Geoform can improve constructability and safety, and geogrid can maintain the shape of concrete.

Geoform is a kind of geo material and can be formed from expanded polystyrene (EPS). The geoform may be formed in a standardized shape, such as a rectangular parallelepiped. Geoform may be laminated on the foundation floor (B). The geoform may be an Embedded Geo-material Installation (EGI). According to the geoform, since conventional rubble is not used, the safety of construction can be increased.

These geoforms can be constructed in a modular way. That is, the geoform may be manufactured in advance and then laminated at the installation site. Because geofoam is a lightweight material, transportation costs to the site and production costs on site can be saved.

The geogrid and concrete composite may be cast on the geoform to form the appearance of the dam body 100 , the dam shoulder 200 , and the like. The geogrid can control the floating property of the geoform and maintain the shape of the concrete.

The use of geoforms and geogrids can inhibit brittle fracture and induce ductile failure that can be destroyed slowly even in danger. In addition, seismic performance can be improved in seismic behavior. As a result, damage to residential areas located near mountainous areas such as Namhyeon-dong and Bukhansan can be minimized.

The dam body 100 may include a plurality of pillars 110 . The pillar 110 may be formed in a rectangular parallelepiped shape. The plurality of pillars 110 may be disposed to be spaced apart from each other in the lateral direction. The pillar 110 may be located between a pair of dam shoulders 200 , and the pillar 110 located at the outermost side may be spaced apart from the dam shoulder 200 . The pillar 110 may be formed to have a lower height than the dam shoulder 200 .

The dam body 100 may further include lower structures 120 and 120 . The lower structures 120 and 120 may be installed under the plurality of pillars 110 to support the pillars 110 . The lower structures 120 and 120 may be formed to connect a pair of dam shoulders 200 . The lower structures 120 and 120 may be configured to form a step difference between the upstream portion 10 and the downstream portion 20 .

The dam body 100 may be formed with a waterproof passage (A). The waterway (A) is a passage formed in the dam body 100 to move water from the upstream part 10 to the downstream part 20 . The spillway (A) may be located between a pair of dam shoulders (200).

When the dam body 100 includes a plurality of pillars 110 , the waterproof passage A may be formed by a space between the plurality of pillars 110 . Since the plurality of pillars 110 are spaced apart from each other, a space may be formed between the adjacent pillars 110 , and the space may serve as a waterproof passage (A). That is, the water of the upstream part 10 may move to the downstream part 20 through the space between the plurality of pillars 110 . In addition, the waterproof passage (A) may be formed on the upper side of the lower structure (120).

When the dam body 100 includes a plurality of pillars 110 and the space therebetween is used as the waterproof passage A, the waterproof passage A may perform a function of filtering large foreign substances.

Sidewalls 300 , 310 , and 320 may be installed in each of the upstream portion 10 and the downstream portion 20 . The side walls 300 , 310 , and 320 may be installed on each side of the upstream part 10 and the downstream part 20 . The sidewalls 300 , 310 , and 320 may provide an accommodating space for water for each of the upstream part 10 and the downstream part 20 . That is, water may be accommodated inside the sidewalls 300 , 310 , and 320 .

The sidewalls 300 , 310 , and 320 may be formed in a stepped manner. The stepped sidewall can harmonize with the topography of the mountain where the dam is installed.

A planting space (P) is provided on the upper surface of the side walls (300, 310, 320), and the side wall may be responsible for a storage function, a vegetation function, etc. in addition to the function of providing the above-described water receiving space. Planting is possible in the planting space P, so that plants such as shrubs and plants can grow. Accordingly, it is possible to create an eco-friendly four-way dam landscape.

In addition, the soil provided for the planting space (P) can absorb, store, and discharge water, and it flows into the planting space (P) by connecting the planting space (P) and the ground (or other areas requiring water) The recovered water can be further used in the ground (or other areas where water is needed).

By having the sidewall including the planting space P, the sidewall can function as a LID (low impact development) facility.

The water cushion 400 is located on the bottom of the downstream part 20 , and may be coupled to the sidewall 300 of the downstream part 20 . Since the water cushion 400 is located on the bottom of the downstream part 20 , the water cushion 400 can protect the bottom of the downstream part 20 from water falling from the upstream part 10 .

The water cushion 400 may open and close the bottom of the downstream part 20 . That is, the water cushion 400 may be selectively present or absent. For example, when water falls from the upstream part 10 to the downstream part 20 , the water cushion 400 may exist to close the bottom of the downstream part 20 . In addition, in the absence of water, it may be absent to open the bottom of the downstream part 20 .

The water cushion 400 may include a door D movably coupled to the sidewall 300 of the downstream part 20 . The door (D) may be formed in one or a plurality. The door D is movable transversely with respect to the side wall.

The door (D) is formed as one, but may be formed in multiple stages. When the bottom of the downstream part 20 is closed, the door D is spread out in multiple stages, and when the bottom of the downstream part 20 is opened, all of the multiple stages may be overlapped.

The door D is formed in two, and each door D may be respectively coupled to both sidewalls 300 of the downstream part 20 . The two doors D may close the bottom of the downstream portion 20 while moving inward from both sidewalls 300 of the downstream portion 20 . The two doors D may open and close the bottom of the downstream part 20 while moving in opposite directions.

Here, the lateral width of one door D may be equal to the lateral width of the sidewall 300 and may be equal to half the width of the downstream portion 20 . According to this, the door D is located inside the sidewall 300 so as not to be exposed to the outside when the bottom of the downstream part 20 is opened, and escapes from the sidewall 300 when the bottom of the downstream part 20 is closed to escape from the downstream part 20 ) can be located on the top of the floor.

The water cushion 400 may further include a driving unit for moving the door D, and the driving unit may include an electric roller. The electric roller (driver) may be coupled to the door (D) to provide power to move the door (D).

According to the water cushion 400 that can be opened and closed, the four-way dam can be used not only as a disaster prevention function, but also as a leisure function, a fire protection water supply function, and the like while opening and closing the water cushion 400 as necessary.

During a period of heavy rainfall (eg, in summer), the water cushion 400 may close the bottom of the downstream part 20 and perform a downward erosion prevention function, which is the main function of the water cushion 400 . Also, at this time, the water can flow down, providing a leisure space for people.

In addition, in a period of low rainfall (eg, autumn), the water cushion 400 opens the bottom of the downstream part 20 to mainly perform the function of storing water rather than the main function of the water cushion 400, and receives water space can be increased. This stored water can be used for fire protection. In particular, in case of a wildfire, it is important to secure fire prevention water from the vicinity. Since the four-way dam formed in the mountain can store a large amount of water, it can function as a fire protection water supply facility for wildfires.

In addition, the water cushion 400 may be opened or closed to enable sports or leisure in the four-way dam.

A four-way dam including an openable and openable water cushion 400 according to an embodiment of the present invention may further include a water level sensor and a control unit.

When the value measured by the water level sensor is equal to or greater than the preset value, the water cushion 400 may close the bottom of the downstream part 20 . For example, the water level sensor may check the time when the upstream part 10 starts to overflow the dam body 100 . Accordingly, a preset value may be determined. The preset value may be the same as the height of the dam body 100 or the height of the lower structure.

The controller may control the movement of the water cushion 400 . When the value measured by the water level sensor is greater than or equal to a preset value, the controller may control the water cushion 400 to close the bottom of the downstream part 20 . The control unit may control a driving unit such as an electric roller, and may be controlled by wire and/or wirelessly.

According to the water level sensor and the control unit, the water cushion 400 may be automatically opened and closed. In addition, the water cushion 400 may be opened and closed remotely.

In this case, water may move from the first downstream part 21 to the second downstream part 22 . That is, a step may be formed between the first downstream portion 21 and the second downstream portion 22 , and the step may be provided by the partition wall 600 .

The first downstream part 21 may be an inner space of the dam body 100 , the side wall, and the partition wall 600 , and the second downstream part 22 may be an inner space of the partition wall 600 and the side wall.
