Description

Technology Field

[0001] The present invention relates to a buoyancy-type water barrier system installed at the entrance of an underground facility, and more specifically, to a buoyancy-type water barrier system installed at the entrance of an underground facility that prevents the underground facility from being flooded and prevents damage to the building caused by rainwater by blocking the inflow of rainwater through the buoyancy-type water barrier, by installing a buoyancy-type water barrier that rises and falls in proportion to the amount of rainwater inflow. Background Technology

[0002] Recently, due to factors such as climate change, the frequency of abnormal rainfall events exceeding the design capacity of various hydraulic structures has been rapidly increasing. Along with abnormal rainfall, the frequency and scale of factors that hinder water cutoff management—such as monsoons, typhoons, and strong winds—are also rising. However, specific design standards for buildings and facilities to prepare for these situations—specifically, water-resistant design standards—have not yet been established. Consequently, as casualties and property damage are on the rise not only in historically flood-prone areas but also in previously relatively safe urban centers, research is underway to develop measures to mitigate flood damage; however, the current situation remains insufficient.

[0003] Typically, residential spaces such as apartments and mixed-use buildings, as well as office spaces such as office buildings, are equipped with single-story or multi-story underground parking lots to accommodate the vehicle ownership of residents.

[0004] Recently, due to environmental issues such as global warming, torrential rains are occurring frequently regardless of the season. When such heavy rains occur, rainwater overflows instantaneously into the basements of buildings located in low-lying areas; undrained rainwater then flows into internal parking spaces through entrances, causing significant property damage.

[0005] In other words, when heavy rain occurs and a large amount of rain flows onto the ground, the rainwater flows into the underground parking lot through the entrance and exit along the sloping entrance. While small amounts of rainwater entering the underground parking lot are drained through drainage channels, if a large amount of rainwater flows in instantaneously, flooding occurs in the underground parking lot, at which point the water is forcibly drained using a separately prepared drainage pump. However, if heavy rain persists for a long time, the amount of water flowing in exceeds the amount discharged by the drainage pump, resulting in flooding. Furthermore, there was a problem where not only vehicles but also various electrical equipment installed in the underground structure were submerged during flooding.

[0006] To solve this, sandbags and other materials are stacked in multiple layers on the access road leading to the underground parking lot to prevent rainwater from flowing into the underground, but this has been a difficult problem as it requires rapid work.

[0007] Recently, Patent Publication No. 10-2012-0122504 disclosed a rainwater inflow prevention device, which comprises an installation bracket provided on the floor surface, a water barrier rotatably hinged to the installation bracket, and a support member that supports the water barrier elastically through an elastic member so that it is set up at an angle in the direction of vehicle movement to block rainwater, causes the water barrier to tilt when external pressure is applied, and restores the water barrier to its initial position when the external pressure is released.

[0008] Accordingly, when rainwater occurs, the installation bracket is positioned at an angle using the elastic force of the elastic member to block the rainwater.

[0009] The aforementioned technology has the problem of being unable to withstand high water pressure and being difficult to install, as it supports the water barrier through an elastic member when rainwater flows in.

[0010] In addition, Patent Publication No. 10-2013-0112355 discloses a water barrier device, which includes a pair of walls having an entrance, with both edges attached to the wall and a bottom portion in contact with the floor of the entrance to block rainwater; and a packing member provided between the water barrier and the wall to prevent the inflow of rainwater, wherein the water barrier blocks the inflow of rainwater by pushing the packing member against the wall by the water pressure of the rainwater.

[0011] However, the aforementioned technology has the problem that the water barrier is aesthetically unpleasing and obstructs vehicle traffic because it is normally exposed to the outside. Prior art literature

Specific details for implementing the invention

[0029] The present invention according to a preferred embodiment will be described in detail below with reference to the attached drawings. Here, the same reference numerals are used for identical components, and repetitive descriptions and detailed descriptions of known functions and components that may unnecessarily obscure the essence of the invention are omitted. The embodiments of the invention are provided to more completely explain the invention to those with average knowledge in the art. Accordingly, the shapes and sizes of elements in the drawings may be exaggerated for clearer explanation.

[0030] FIG. 1 is a perspective view of a buoyancy-type water barrier system installed at the entrance of an underground facility according to the present invention before the operation of the water barrier, FIG. 2 is a perspective view of a buoyancy-type water barrier system installed at the entrance of an underground facility according to the present invention after the operation of the water barrier, and FIG. 3 is a perspective view illustrating the internal structure of a buoyancy-type water barrier system installed at the entrance of an underground facility according to the present invention.

[0031] Referring to FIGS. 1 to 3, a buoyancy-type water barrier facility (100) according to an embodiment of the present invention may largely include a buoyancy-type water barrier (110); a first compartment (111); a rainwater trench (130); and a second compartment (131).

[0032] The above-mentioned buoyancy-type water barrier plate (110) can be installed at the entrance of an underground facility (10). At this time, the underground facility (10) includes underground parking lots, basements, underground shopping malls, underground passages, etc., and the present invention describes an underground parking lot as an example only and is not limited thereto.

[0033] The buoyancy-type water barrier plate (110) according to the present invention is installed by being buried in the longitudinal direction at the entrance of an underground facility (10), and when heavy rain falls, it is raised and lowered by buoyancy in conjunction with the amount of rainwater flowing in, causing it to protrude above ground and block the entrance of the underground facility (10).

[0034] Such a buoyancy-type water barrier (110) can be operated to move up and down along rail-structured lifting guides (120) installed on both sides of the entrance of the underground facility (10).

[0035] The above lifting guide (120) supports both ends of the buoyancy-type water barrier plate (110) so as to be slidably moved only in the vertical direction, and can provide a rail-shaped structure. Although the above lifting guide (120) is illustrated in FIGS. 1 and 2 as a "C"-shaped guide structure, it is not limited thereto, and various types of guide structures capable of maintaining watertightness can be applied.

[0036] The buoyancy-type water barrier plate (110) according to the present invention may be manufactured as a hollow casing. At this time, air may be filled inside the hollow casing so that buoyancy can be applied. At this time, a gas flow with a density lower than that of air may be filled inside the hollow casing.

[0037] In addition, the above-mentioned buoyancy-type water barrier (110) may be made of a material such as aluminum alloy or synthetic resin to reduce weight.

[0038] In addition, the above-mentioned buoyancy-type water barrier (110) can be formed so that the interior of the hollow hull has a porous layer structure or is filled with a porous layer structure.

[0039] For example, the interior of the hollow hull can be divided into multiple compartments to provide a porous layer structure so that the buoyancy-type water barrier (110) has strength against water pressure. In this case, the shape of the compartment may be a porous layer structure such as a checkerboard shape or a honeycomb shape.

[0040] In addition, the porous layer structure may be a styrofoam structure or a similar structure.

[0041] Additionally, at least one surface of the outer surface of the buoyancy-type water barrier plate (110) may be formed from a metal plate or a durable material that provides wear resistance and strength, such as a metal plate. In this case, the surface on which the durable material is formed may be a contact surface that frequently comes into contact with external factors, such as a contact surface with a lifting guide (120) or a vehicle contact surface.

[0042] The above-mentioned buoyancy-type water barrier plate (110) can be slidably accommodated in a first compartment (111) installed underground.

[0043] At this time, the first compartment (111) is filled with rainwater flowing into the lower space of the buoyancy-type water barrier (110) to provide buoyancy to the buoyancy-type water barrier (110), and can provide a space in the shape of a hull having a larger volume than the buoyancy-type water barrier (110).

[0044] At this time, the buoyancy-type water barrier plate (110) touching the bottom of the first compartment (111) can be protruded above the ground and used as a speed bump on the vehicle's path.

[0045] A rainwater trench (130) may be installed in front of the above-mentioned buoyancy-type water barrier (110). At this time, the rainwater trench (130) may serve to drain rainwater flowing into the entrance of the underground facility (10) and to act as a speed bump to prevent vehicles from speeding.

[0046] The above-mentioned excellent trench (130) may be provided with a structure that forms a plurality of through holes in a curved, curved barrier structure.

[0047] In addition, the above-mentioned excellent trench (130) can be made of a rigid material capable of withstanding the load when a vehicle passes through. More specifically, it can be made of a metal casting.

[0048] In addition, the upper side of the buoyancy-type water barrier plate (110) can be formed in a curved shape so as to be connected to the extension line of the curved shape of the above-mentioned rainwater trench (130), thereby forming a barrier connected to the rainwater trench (130) and the buoyancy-type water barrier plate (110).

[0049] Such excellent trenches (130) can be installed at both the front and rear of the buoyancy-type water barrier (110).

[0050] At this time, the rainwater trench (130) installed behind the buoyancy-type water barrier (110) can serve as an alternative solution for introducing rainwater in situations where the rainwater trench (130) in front of the buoyancy-type water barrier (110) is blocked by external factors and rainwater cannot be introduced in time.

[0051] A second compartment (131) can be formed in the lower part of the above-mentioned rainwater trench (130) to accommodate a certain volume of incoming rainwater. At this time, the volume of the second compartment (131) can be formed larger than the volume of the first compartment (111). The second compartment (131) can form a rainwater receiving space of sufficient width to provide enough water pressure to raise and lower the buoyancy-type water barrier plate (110) by buoyancy.

[0052] The water pressure formed within the second compartment (131) can be transmitted to the first compartment (111) through a bypass hole (113) that forms a passage to communicate with the second compartment (131), thereby allowing the buoyancy to be applied so that the buoyancy barrier plate (110) is raised and lowered.

[0053] At this time, the bypass hole (113) can form a passage that penetrates from the bottom side of the second compartment (131) to the bottom side of the first compartment (111).

[0054] The operation of the present invention is described below.

[0055] First, when rainwater that has not been drained through the drainage facility and flows back into an underground facility (10), such as an underground parking lot, in a situation such as heavy rain, most of the rainwater is guided to flow into the second underground compartment (131) from the rainwater trench (130).

[0056] At this time, as rainwater continuously flows into the second compartment (131) and a certain water pressure is formed, the water pressure in the first compartment (111) rises, causing the buoyancy-type water barrier plate (110) to be raised by buoyancy.

[0057] At this time, the buoyancy-type water barrier plate (110) is raised along the lifting guide (120) to block the entrance of the underground facility (10) so that rainwater inflow is blocked.

[0058] At this time, when rainwater continuously flows in through the rainwater trench, the buoyancy-type water barrier (110) remains in a rising state, and when the rain stops and no more rainwater flows in, the buoyancy-type water barrier (110) descends due to its own weight.

[0059] At this time, a drainage hole may be formed in the first compartment (111) or the second compartment (131) so that rainwater drains out to an external drainage facility, and when all the rainwater that had flowed in through this drainage hole drains out, the lower end of the buoyancy-type water barrier plate (110) comes into contact with the bottom of the first compartment (111).

[0060] At this time, the upper side of the buoyancy-type water barrier plate (110) can be positioned so that it protrudes slightly above the ground, thereby serving as a speed bump.

[0061] According to the buoyancy-type water barrier system installed at the entrance of underground facilities as previously examined, it is possible to prevent casualties and property damage by blocking rainwater flowing into the underground parking lot. Furthermore, as the rainwater gradually rises, the buoyancy-type water barrier operates to move up and down in proportion to the position of the rainwater, thereby effectively blocking rainwater caused by heavy rainfall.

[0062] In addition, according to the present invention, by using an aluminum alloy as the material for the buoyancy-type water barrier, it is about one-third lighter than stainless steel, about 10 to 20 percent cheaper than a stainless steel water barrier, and can provide the advantages of excellent corrosion resistance.

[0063] In addition, according to the present invention, when heavy rain causes the drainage system to backflow and the water level to rise, the water barrier rises due to buoyancy, so rainwater can be blocked without the use of a separate device or energy source, and on days when it does not rain, the water barrier acts as a speed bump that induces low-speed driving of vehicles, thereby reducing the risk of accidents at the entrance of an underground parking lot.

[0064] The present invention has been described with reference to an embodiment illustrated in the accompanying drawings, but this is merely illustrative, and those skilled in the art will understand that various modifications and equivalent alternative embodiments are possible therefrom. Accordingly, the true scope of protection of the present invention should be determined only by the appended claims. Explanation of the symbols
