Description

{WATER DEFENCE APPARATUS FOR UNDERGROUND ENTRANCE}

The present invention relates to a water shutoff device, and in detail, a water shutoff plate made of metal, one end of which is bent upward at 45 degrees and the other end bent at a downward angle of 45 degrees, is rotatably coupled with a water shutoff plate adjacent above and below using a hinge. This relates to an underground entrance water blocking device that folds into a bellows shape to minimize installation and storage volume and prevents the water blocking plate from being damaged by sharp objects washed up in rainwater.

Generally, in order to access underground facilities such as subway stations, underground parking lots, underpasses, and underground shopping malls, entrances to these facilities are installed on the ground, and users enter and exit the underground facilities through these entrances. Moreover, subway entrances primarily serve as water barriers by installing stairs higher than the ground.

However, due to recent abnormal weather conditions caused by global warming, localized heavy rains are occurring frequently, and as a result, rivers are overflowing or rainwater is not drained in a timely manner, resulting in frequent flood damage. In addition, rainwater that rapidly increases due to localized heavy rain quickly flows into underground facilities, causing flooding damage.

In particular, when flooding damage occurs in underground facilities, it is not only difficult to pump out rainwater that has flowed into underground facilities, but also causes significant economic losses. Therefore, in the past, methods such as piling sandbags at underground entrances were used. However, this method is not effective in blocking rainwater and is not easy to work with quickly.

To solve this problem, a water-blocking device installed at an underground entrance has been proposed.

As an example of such a water-watering device, domestic patents No. 10-1270137, No. 10-132548, and No. 10-1875567 are disclosed.

As shown in FIG. 1, the blind-type water barrier device, which is domestically registered patent number 10-1270137, is installed with a water barrier storage box (10) attached vertically to the right edge of the subway entrance, and a water barrier storage box to the left edge. A fastening member box 20 accommodating a fastening member 22 for fixing the car cloth 11, which is fixedly coupled to the car cloth 11 when the car cloth 11 accommodated in (10) is unfolded, is installed vertically.

However, this type of blind water barrier device cannot be shut off if the water barrier is damaged by a sharp object washed up in rainwater, and since a holder block must be installed separately at the entrance, installation may take a lot of time.

In addition, the water stopper for subway and building external entrances, which is Domestic Patent No. 10-132548, includes a base member 10 embedded in the bottom surface of the external entrance as shown in FIG. 2, and the base member 10. It is configured to include a plate 20 to be accommodated and a pair of posts 40 erected on both sides of the base member 10 and the plate 20, respectively.

However, these water barriers for subway and exterior entrances to buildings require a relatively large installation area because the water barriers are stored and operated in a folded state, and as a result, they are prone to being damaged by load when multiple users step on them at the entrance. There is a problem.

As shown in FIG. 3, the foldable water blocking device, which is the domestic patent registration number 10-1875567, is a water blocking device formed at the entrance to an underground space or a building entrance, and is a water blocking device formed along the width direction on the bottom surface of the entrance to the underground space. space(10); Support pillars (20) each fixed to both side walls of the underground space entrance; A water shield (30) that is folded and stored in the water shield storage space, the lower end of which is fixed to the inner surface of the water shield storage space, and when unfolded, both side ends are in contact with the support pillar; And a pressure bar (40) formed at both ends of the width direction of the underground space entrance and rotating about a rotation axis parallel to the support pillar, and pressuring the side end of the water barrier to the support pillar according to the rotation angle; and a second support pillar 60 that is spaced apart from the support pillar so that the pressure bar is positioned between the support pillars and forms a storage space for the pressure bar.

However, this foldable water barrier device cannot be water blocked if the water barrier is damaged by a sharp object carried by rainwater, and even if the water barrier is pressed with a pressure bar, a gap occurs when the water barrier is stretched laterally by the rainwater load. , there is a problem that the fixation of the pressure bar and water barrier may be released when the pressure becomes relatively high.
