The sluice system according to the present embodiment may include a sluice gate 10 , a first space part 20 and a second space part 30 .

The water gate 10 is installed on the tunnel entrance side and serves to selectively close the tunnel entrance. The sluice gate 10 normally keeps the entrance side of the tunnel where vehicles enter and exit in an open state, but is closed when heavy rain or flooding of nearby rivers is concerned, and can be installed to block rainwater from entering the tunnel. there is. According to this embodiment, the water gate 10 can be opened and closed to a first position for closing the tunnel entrance and a second position for opening the tunnel entrance.

At least one first roller 11 and one or more second rollers may be provided on both side walls of the water gate 10 . The first and second rollers may be configured to easily move along first and second rails 110 and 120 to be described later during the process of raising and swinging the water gate.

A hinge portion serving as a rotational center of swing rotation may be provided at an upper end of the sluice gate 10 . As shown as being provided on one side of the upper end of the sluice gate 10, the hinge portion may protrude a predetermined length toward the bottom surface in an open position. The hinge unit may be provided to move up and down along a third rail 130 to be described later.

The structure of both ends of the hinge part is composed of an elliptical shape, so when the water gate 10 moves in the vertical direction to be lifted, the short width (a) moves horizontally, and after the vertical lifting is completed, the swing rotation of the water gate 10 is performed. In this case, the long width (b) is rotated in a horizontal direction, and as shown in FIG. 8 , it may be supported on the upper end side of the third rail 130 . Through this configuration, when the rotation of the sluice gate 10 is completed, the long width (b) of the hinge part becomes completely horizontal, and deflection due to the weight of the sluice gate 10 can be prevented, and the first and second pulleys 220 ( 230), the weight of the water gate 10 can be distributed and supported.

As shown in FIG. 8, an elastic member having a certain height is installed on the bottom surface of the water gate 10 to improve watertightness with the bottom surface. The elastic member is provided as an elastically deformable member made of rubber or similar material, and when the water gate 10 moves to the first position, which is the closed position, it is deformed by the weight of the water gate 10 and the end and bottom surface of the water gate 10 It is possible to make the sluice mounting groove provided in close contact as much as possible.

The first space 20 forms a space at the entrance of the tunnel where the water gate 10 can be disposed between the first and second positions, as shown in FIGS. 7 and 8, Guide rail units 100 for guiding opening and closing paths of the water gate 10 may be installed on both side walls of the first space 20 . In addition, the upper side of the first space portion 20 may extend to the ceiling surface of the entrance side of the tunnel, and the water gate 10 may be opened to the inside of the ceiling surface with the tunnel entrance open.

In addition, as shown in FIG. 8 , the bottom surface of the tunnel constituting the first space portion 20 may be installed inclined at a certain angle α towards the inside of the tunnel. This is because the construction of the tunnel is generally configured to face the underground, and may be configured to have an inclination angle in the opposite direction.

In addition, as shown in FIG. 7 , the bottom surface may be inclined toward one side of the wall surface. If the bottom surface is formed to have a gradient in this way, water can be more easily drained in one direction.

Guide rail units 100 guiding an opening and closing operation path of the water gate 10 may be installed on both side walls of the first space 20 .

The guide rail unit 100 according to this embodiment may include a first rail 110 , a second rail 120 and a third rail 130 .

The first rail 110 is formed on both side walls of the tunnel and may extend in a vertical direction with respect to the floor surface. At this time, a ladder part may be formed on the first rail 110 so that a worker can climb upward, and through this ladder part, it is possible to approach the third rail 130 to be described later and perform maintenance work. The first rail 110 may be formed in a direction perpendicular to the floor surface during the first height h1 section in which the water gate 10 rises, and may be formed symmetrically on both side walls of the tunnel. The width of the first rail 110 may be formed to have a width corresponding to the diameters of the first and second rollers formed on both side walls of the water gate 10, but may have a gap of less than 1 cm. Accordingly, when the first and second rollers ascend or descend along the inner wall surface of the first rail 110, they can guide the moving path of the water gate while gently rotating.

In addition, the first rail 110 may form a guide rail having a certain height even on the upper side of the portion connected to the second rail 120, which is a path in which the second roller rises by the first height h1. It is designed to guide.

The second rail 120 is connected to the rear of the first rail and may be provided in an arc shape so that the water gate 10 vertically raised during the first height h1 can rotate around the hinge part. According to this embodiment, the rotation radius of the second rail 120 may correspond to the distance between the hinge part and the central axis of the first roller. The width of the second rail 120 may also be prepared to correspond to the width of the first rail 110 . At this time, since the sluice gate 10 swings and rotates around the hinge part 13, the first roller moves along the second rail 120, but the second roller does not enter the second rail 120.

The third rail 130 guides the upward path of the hinge part in the vertical direction, and may be formed in the same direction as the first rail 110 as shown in FIGS. 8 to 11 . In addition, the third rail 130 is the upper side of the second space 20 and is provided in front of the upper side of the first rail 110, which is the upper side of the tunnel entrance, in the second position where the water gate 10 is opened. It may be placed at a lower position than the water gate 10 in .

Through this configuration, the first roller 11 rises along the first rail 110 during the process of vertically rising from the first position where the water gate 10 is closed, and when the vertical elevation is completed, the second rail ( 120) to swing and rotate to move to the second position, which is an open position.

On the other hand, as shown in FIG. 8, it is preferable that the tunnel entrance has a second height h2 greater than at least the size of the water gate 10, and the size of the second height h2 of the tunnel entrance is It may be formed larger than the first height h1, which is the height of vertical elevation. That is, it is better to configure the height at which the water gate 10 vertically rises as small as possible. This is because, when the vertical rise width of the water gate 10 is too large, the size of the facility increases as the height of the machine room increases.

Meanwhile, as described above, in order to vertically raise and swing-rotate the water gate 10, the power unit 200 installed in the first and second spaces 20 and 30 is required.

The power unit 200 may include a power unit 210 , a first pulley 220 and a second pulley 230 .

The power unit 210 may be installed in the second space unit 30 and may be composed of power transmission units such as at least one motor and a clutch to transmit rotational power to the side of the first sheave 220 . In the power unit 210 , a power transmission unit such as a motor and a clutch described above may be installed as one module in a base unit fixed to the bottom surface of the second space unit 30 .

As shown in FIG. 8, the first pulley 220 may be disposed below the second space portion 30. As shown in an example, the first and second space portions 20 and 30 are It may be installed to protrude in a direction toward the water gate 10 in the communicating through hole. A cable is wound around the first pulley 220, one end of which is connected to the first pulley 220, and the other end is wound around a second pulley 230 to be described later, interlocking with the rotational motion of the power unit 210. can be wound or released.

The second sheave 230 may be installed on the rear wall side of the gate 10 toward the inside of the tunnel. According to this embodiment, the first and second sheave 220, 230 are formed to have the same standard, , the degree of winding and unwinding of the cable for winding can be configured to be constant.

At this time, the first and second pulleys 220 and 230 may be provided as a pair, and as shown in FIGS. 1 and 2, one each may be formed at a position close to both ends of the water gate 10 close to the side wall. . The first and second pulleys 220 and 230 wind the cable as close as possible so that they can be disposed as close as possible in the open position of the water gate 10 shown in FIG. 8, and in the closed position of the water gate 10 shown in FIG. The cables may be released as much as possible so that the first and second pulleys 220 and 230 can be disposed as far apart as possible.

Meanwhile, at least one pump unit 300 may be further installed at the front end of the sluice gate closing position of the tunnel. The pump unit 300 can be installed inside the side wall of the tunnel and can be selectively operated by a valve member. For example, if water accumulates in front of the sluice gate 10 while the sluice gate 10 is closed, it is possible to quickly discharge it using the pump unit 300 to effectively block rainwater flowing into the tunnel. .

The pump unit 300 can pump water stored inside the U-Type retaining wall at the entrance of the tunnel, and a water pump can be installed at the bottom of the structure to pump water. To this end, it is possible to secure a water pump space by manufacturing a compartment integrated with the structure at the bottom of the wall. In this case, accessibility is good and maintenance is convenient.

Hereinafter, the operation of the sluice gate system according to this embodiment will be described with reference to FIGS. 7 to 11.

In normal times, the tunnel entrance through which vehicles enter and exit may remain open as shown in FIGS. 7 and 8 . At this time, the water gate 10 may be housed horizontally with respect to the floor surface on the upper side of the first space portion 20 through which a vehicle or the like passes. At this time, the space in which the water gate 10 is accommodated corresponds to the ceiling surface inside the tunnel, and maintenance is performed through ladders formed on the first rail 110 and the third rail 130 provided on the side wall side so that it can be easily accessed from the outside. can be performed.

In addition, when it is necessary to block the inflow of rainwater due to occurrence of heavy rain or flood or sudden heavy rain, the water gate 10 swings, rotates and descends from the second position, which is the storage position, to the first position, which is the closing position of the tunnel entrance. You can proceed sequentially.

That is, as shown in FIG. 8, the water gate 10 stored horizontally with respect to the floor can release the cables wound around the first and second pulleys 210 and 220 as shown in FIG. there is. Then, the water gate 10 rotates around the hinge part by its own weight, and accordingly, the distance between the first and second pulleys 210 and 220 may increase. At this time, the first roller of the water gate 10 may swing and rotate along the second rail 120 . At this time, since the hinge part becomes the center of rotation of the water gate 10, the position can be fixed. During this rotation process, the self-weight of the water gate 10 is transferred to the inner wall surface of the second rail 120 through the first roller, and the first roller performs a rolling motion along the inner wall surface of the second rail 120, , so that the water gate 10 can rotate smoothly.

When the water gate 10 performs swing rotation and moves to a position perpendicular to the floor as shown in FIG. 10, the first roller enters the first rail 110 and moves in a direction perpendicular to the floor. The descent path can be guided. At this time, the cables wound around the first and second pulleys 210 and 220 may be continuously unwound to increase the distance between the first and second pulleys 210 and 220 . Then, while the water gate 10 descends downward by its own weight, as shown in FIG. 10, it can descend to the water gate seating groove formed on the floor surface and close the tunnel entrance. At this time, the elastic member installed at the end of the sluice gate 10 seals the space between the sluice gate seating groove and the sluice gate 10, thereby maximally preventing rainwater from entering the tunnel.

According to the present embodiment as described above, the height of the sluice system can be reduced compared to the existing sluice gates of the vertical elevating and descending method, so that the construction is convenient. In addition, it is possible to provide a sluice gate with excellent watertightness compared to a swing type sluice gate.

In particular, it can block the inflow of rainwater into underground facilities such as tunnels, and when applied to sluice systems such as rivers and dams in addition to tunnel entrances, the thickness and strength of sluice gates are maintained while maintaining the structure for lifting sluice gates. volume can be reduced.

This embodiment is merely an example of the technical idea of the present invention, and various modifications and variations of this embodiment can be made by those skilled in the art without departing from the essential characteristics of the present invention. It will be possible.
