The vertical descent type waterproof door has a structure in which the waterproof door is vertically opened and closed while the swing gate waterproof door is opened and closed by rotating the hinge part about the upper part of the watercock by a hinge, .

However, since the vertically descending watertight doors require facilities above a certain height to raise the water gate, it is not suitable to be applied to an underground tunnel system such as passing through a downtown area where a decrease in the size due to a projecting height is likely to occur. In addition, in the case of installing the floodgate by the swing method, it is not necessary to lift the floodgate to open and close the watertight gate, and the size of the facility can be reduced as compared with the general elevating and lowering method. However, have.

In order to solve such a problem, a technique has recently been disclosed which combines the opening and closing methods of these water doors. For example, in Korean Patent No. 10-0995969, there has been mentioned a structure in which a water gate is installed on a water channel facility such as a dam or a seawall using an elevatable gate. In the above-mentioned prior art, it is described that a combination of the advantages of the vertically descending type waterproof door and the swing gate type waterproof door is used to elevate the water gate vertically in a certain section and then rotate it to complement the disadvantages of the vertical descending type waterproof door and the swing gate waterproof door. There is a bar.

As shown in Figs. 1 and 2, 1, a guide rail unit 100 for guiding the opening / closing path of the water gate 10 may be installed on both side walls of the space portion 20. [ In addition, the upper side of the first space 20 can be extended to the ceiling of the entrance of the tunnel, and the water gate 10 can be opened inside the tunnel, with the entrance of the tunnel opened.

The bottom surface 21 of the tunnel constituting the first space 20 may be inclined at an angle? To the inside of the tunnel as shown in FIG. This is generally because the construction of the tunnel is configured to face the basement, and it may be configured to have an inclination angle in the opposite direction.

Also, as shown in FIG. 1, the bottom surface 21 can be inclined toward one side wall. If the bottom surface is formed to have a gradient on the bottom surface, the water can be more easily drained in one direction.

A guide rail unit 100 for guiding the opening / closing operation path of the water gate 10 may be installed on both side walls of the first space portion 20. [

The guide rail unit 100 according to the present 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 direction perpendicular to the bottom surface 21. At this time, a ladder portion may be formed on the first rail 110 so as to be lifted up to the worker, and the ladder portion may approach the third rail 130 to be described later to perform maintenance or the like. The first rail 110 may be formed in a direction perpendicular to the bottom surface during a first height h1 during which the water gate 10 rises and may be formed to be symmetrical to both side walls of the tunnel. The width of the first rail 110 is formed to have a width corresponding to the diameter of the first and second rollers 11 and 12 formed on both side walls of the water gate 10, . Accordingly, when the first and second rollers 11 and 12 are lifted or lowered along the inner wall surface of the first rail 110, the first and second rollers 11 and 12 can smoothly rotate and guide the movement path of the watercourse.

The first rail 110 may also be formed with a guide rail having a predetermined height on the upper side connected to the second rail 120 because the second roller 12 is raised by the first height h1 To guide the path.

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 about the hinge portion 13 . According to the present embodiment, the turning radius of the second rail 120 may correspond to the distance between the hinge portion 13 and the center axis of the first roller 11. The width of the second rail 120 may be set to correspond to the width of the first rail 110. The first roller 11 moves along the second rail 120 while the second roller 12 moves along the second rail 120. In this case, .

The third rail 130 guides the vertical upward direction of the hinge portion 13 and may be formed in the same direction as the first rail 110 as shown in FIGS. The third rail 130 is provided on the upper side of the first rail 110 on the upper side of the entrance of the tunnel as the upper side of the second space 20 and has a second position The water level can be lower than the water level.

Through the above-described structure, the first roller 11 ascends along the first rail 110 during a process of vertically ascending at a first position where the sluice gate 10 is closed, and when the vertical descent is completed, 120 to swing and move to a second position which is an open position.

2, it is preferable that the tunnel entrance has a second height h2 which is greater than at least the size of the water gate 10. The size of the second height h2 of the entrance of the tunnel is equal to the size of the water tunnel 10 May be formed to be larger than the first height (h1) which is the vertical rising height. That is, it is preferable that the elevation height of the water gate 10 is as small as possible because if the vertical elevation width of the water gate 10 is too large, the height of the machine room increases and the size of the facility increases.

Meanwhile, as described above, in order to vertically lift and swing the water gate 10, a power unit 200 installed in the first and second space portions 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 include at least one motor and a power transmission unit such as a clutch to transmit rotational power to the first pulley 220.

For example, as shown in FIG. 2, the first and second spaces 20 and 30 And can be installed so as to protrude in the direction of the water gate 10 in the communicating through hole. The cable 201 is wound on the first pulley 220 and connected to the first pulley 220 at one end and to the second pulley 230 at the other end to rotate the power unit 210 The cable 201 can be wound or unwound.

The second pulley 230 may be installed on the rear wall side of the water tunnel 10 toward the inside of the tunnel. According to the present embodiment, the first pulley 220 and the second pulley 230 are formed to have the same size , The degree to which the cable 201 is wound and unwound for winding can be made constant.

At this time, the first and second pulleys 220 and 230 may be provided in pairs, and one each may be formed at positions close to both ends of the water gate 10 near the side wall as shown in FIGS. 1 and 2 . The first and second pulleys 220 and 230 are wound as far as possible so that the first and second pulleys 220 and 230 can be disposed as close as possible to the open position of the water gate 10 shown in FIG. In the closed position, the cable 201 can be released as much as possible so that the first and second pulleys 220 and 230 can be arranged as far as possible.

The pump unit 300 may be installed inside the side wall of the tunnel, and may be selectively operated by the valve member 310. For example, if the water is heated to the front side of the water gate 10 in a state where the water gate 10 is closed, the water can be quickly discharged using the pump unit 300 to effectively shield the water flowing into the tunnel .

The pump unit 300 can pumped the water inside the U-type retaining wall at the entrance of the tunnel, and the water pump can be installed at the bottom of the structure to pump the pumped water. For this purpose, a compartment integrated with the structure at the bottom of the wall can be manufactured to secure the underwater pump space. In this case, accessibility is good and maintenance is convenient.

Hereinafter, the operation of the hydrological system according to the present embodiment will be described with reference to Figs. 1 to 5. Fig.

The entrance of the tunnel in and out of the vehicle can be maintained in an open state as shown in FIGS. 1 and 2 at normal times. At this time, the water gate 10 may be housed so as to be horizontal with respect to the floor surface 21 on the upper side of the first space portion 20 through which the vehicle or the like passes. At this time, the space in which the water gate 10 is housed corresponds to a ceiling scene inside the tunnel, and the first rail 110 and the third rail 130, which are provided on the side wall side, Can be performed.

When it is necessary to block the influx of rainfall due to heavy rain or flood, or sudden heavy rain, the water gate 10 moves from the second position, which is the storage position, to the first position, which is the tunnel entrance closing position, And can proceed sequentially.

That is, as shown in FIG. 2, the water gate 10, which is housed so as to be horizontal with respect to the bottom surface 21, is connected to the cable wound around the first and second sheaves 210 and 220 (201). Then, the water gate 10 rotates about the hinge portion 13 by its own weight, so that the distance between the first and second pulleys 210 and 220 can be increased. At this time, the water gate 10 can swing the first roller 11 along the second rail 120. At this time, since the hinge portion 13 serves as the center of rotation of the water gate 10, the position can be fixed. During the rotation process, the weight of the water gate 10 is transmitted to the inner wall surface of the second rail 120 through the first roller 11, and the first roller 11 rotates the inner wall surface of the second rail 120 Thereby performing a rolling operation so that the water gate 10 can be smoothly rotated.

4, the first roller 11 enters the first rail 110 and moves to the bottom of the first rail 110. When the first roller 11 moves to a position perpendicular to the bottom surface 21, The downward path can be guided in a direction perpendicular to the first direction (21). At this time, the cable 201 wound on the first and second sheaves 210 and 220 can continue to be unwound and the distance between the first and second sheaves 210 and 220 can be increased. Then, the water gate 10 descends downward due to its own weight, and can descend to the water receiving recess 21a formed on the bottom surface 21 as shown in Fig. 5 to close the tunnel entrance. At this time, the elastic member 15 provided at the end of the water gate 10 seals a space portion between the water entrance seating groove 21a and the water gate 10, and it is possible to prevent the water flow into the inside of the tunnel as much as possible.

According to the present embodiment as described above, the height of the hydrological system can be reduced as compared with the existing vertically ascending and descendent hydrants, and the construction is convenient. Also, it is possible to provide a water gate having excellent watertightness compared to a swing type water gate.

In particular, it is possible to block the entry of rainwater into underground facilities such as tunnels. In addition to tunnel entrance, when applied to hydrological systems such as rivers and dams, The volume can be reduced.
