Description

Rainwater blocking system {RAINWATER BLOCKING SYSTEM FOR DRIVEWAY}

The present invention relates to a rainwater blocking system, and more particularly to a rainwater blocking system that can effectively block the rainwater flowing into the lowland in the rainy weather.

In general, a road is divided into a driveway through which vehicles pass and a footpath walked by pedestrians.

By the way, when rainwater rained down on the road in rainy weather rapidly flows from the highlands into the lowlands, rainwater flows back from the drainage of the roads, and roads located in the lowlands may be flooded quickly.

Moreover, if the rainwater falling on the road rapidly flows into the roadway located in the lowlands while the vehicle is passing through the roadway, there is a problem that the vehicle passing through the roadway is in danger.

Therefore, the road should be able to be provided with blocking and drainage facilities to prevent the rainwater rained down during rainy weather to enter the lowlands (for example, driveway) rapidly. In particular, the road provided in the tunnel should be provided with a blocking device for suppressing the rapid inflow of rainwater rained down in the rain.

Accordingly, in recent years, various studies have been made on the technology for suppressing the rapid inflow of rainwater on the rainy season road into the lowlands, but it is still insufficient and there is an urgent need for development thereof.

It is an object of the present invention to provide a rainwater blocking system that can effectively block rainwater flowing into the lowland in the rainy weather.

In particular, it is an object of the present invention to effectively block rainwater flowing into the roadway located in the lowlands from the sidewalk located in the highlands, and to prevent flooding of the roadway.

In addition, an object of the present invention is to simplify the equipment and to facilitate maintenance and repair.

It is also an object of the present invention to be able to operate the floating barrier which selectively blocks the boundary region of the high and low land in a non-powered manner.

In addition, an object of the present invention is to prevent damage to the lowland by rainwater, and to improve the utilization and stability of the road.

According to a preferred embodiment of the present invention for achieving the above object of the present invention, the rainwater blocking system for blocking rainwater flowing into the lowland in the highlands, trenches formed in the boundary region between the highland and the lowland, and flows into the trench And a floating barrier that selectively floats in response to the level of the rainwater to be prevented from entering the lowlands from the highlands.

This is to effectively suppress rainwater flowing into the lowland from the highlands of rainy weather.

That is, when rainwater rained down on the road in rainy weather rapidly enters the lowlands, rainwater flows back from the drainage of the road, and there is a problem that the road located in the lowlands floods quickly. In particular, when a vehicle is passing through a roadway (for example, an underground roadway), if rainwater falling on the road rapidly flows into a roadway located in a lowland area, there is a problem that a vehicle passing through the roadway is in danger.

However, the present invention is to arrange the floating barrier in the trench formed in the boundary region of the high and low land, and to float the floating barrier in response to the level of rainwater flowing into the trench, so that the rainwater rained down on the road during rainy weather from the high ground to the low land Since the inflow can be minimized, it is possible to obtain a beneficial effect of preventing damage to the lowlands by rainwater and improving the utilization and stability of the road.

Above all, the present invention achieves an advantageous effect of simplifying the installation and facilitating maintenance and maintenance by allowing the floating barrier to operate in response to the level of rainwater flowing into the trench without using a separate power source. Can be.

In other words, it is also possible to configure the floating barrier to be elevated by a drive source such as a motor. However, in order to install the motor in the trench into which rainwater flows, the waterproofing of the motor is required, and thus, the structure and the installation are complicated, and the cost of the facility increases. However, in the present invention, since the floating barrier can be operated without power without using a driving source such as a motor, the structure and installation are easy, maintenance and repair are very easy, and the advantageous effect of lowering the equipment cost can be obtained. .

More specifically, the floating barrier is selectively floated according to the level of rainwater flowing into the trench, and moves from the standby position accommodated in the trench to the blocking position projecting out of the trench.

At this time, in the standby position, the floating barrier is completely received inside the trench without protruding out of the trench. On the other hand, in the blocking position, the floating barrier is arranged to protrude to the top of the trench in a floating state. When the floating barrier is placed in the blocking position, a blocking wall is formed to block rainwater as the floating barrier protrudes to the top of the trench, and the rainwater flowing down from the highlands is blocked by the floating barrier without flowing into the lowland.

The structure and shape of the floating barrier can be varied in various ways depending on the requirements and design specifications.

Preferably, the floating barrier is formed in a shape having a cross-sectional area gradually expanded from top to bottom. More preferably, the floating barrier is formed in the shape of a trapezoidal cross section.

As such, by forming the bottom width of the floating barrier larger than the top width, it is possible to more stably tolerate the water pressure due to rainwater in the state where the floating barrier is raised to the blocking position, and to minimize deformation and breakage of the floating barrier by water pressure. Advantageous effects can be obtained.

In addition, the rainwater blocking system includes a connection passage connecting the trench and the low zone, and an on-off valve for selectively opening and closing the connection passage.

More specifically, when the on-off valve blocks the connection passage, the floating barrier is supported by the rainwater introduced into the trench. On the contrary, when the open / close valve opens the connection passage, the rainwater introduced into the trench is drained through the connection passage to the drainage passage of the low zone.

In addition, the opening and closing valve can be configured to be opened or closed manually by a manual operation of the operator, or automatically opened and closed by a remote operation.

The rainwater blocking system also includes a stopper that restrains the floating barrier from lifting above the reference flotation height range.

The stopper can be formed in a variety of structures that can restrain the floating barrier from lifting above the reference flotation height range. As an example, the stopper protrudes from the inner wall surface of the trench, and when the floating barrier floats to a reference lift height range, the stopper contacts the outer surface of the floating barrier and constrains the floating barrier.

The rainwater blocking system also includes a guide for guiding the vertical movement of the floating barrier with respect to the trench.

As described above, by guiding the vertical movement of the floating barrier with respect to the trench by the guide portion, an advantageous effect of suppressing abnormal flow of the floating barrier and stably maintaining the attitude of the floating barrier can be obtained.

The guide part may be formed in various structures capable of guiding the vertical movement of the floating barrier with respect to the trench. For example, guide grooves are formed in the inner wall of the trench along the vertical direction, and the end of the floating barrier is received in the guide groove so as to be movable along the guide groove.

The rainwater blocking system also includes a first sealing member for sealing a gap between the guide groove and the floating barrier.

As such, by allowing the first sealing member to seal the gap between the guide groove and the floating barrier, an advantageous effect of minimizing the introduction of rainwater into the low water through the gap between the guide groove and the floating barrier can be obtained.

That is, in order to prevent the inundation of the low land in rainy weather, it should be possible to minimize the leakage of rainwater while the floating barrier is raised to the blocking position.

However, in order to ensure the vertical movement (flotation) of the floating barrier in the trench, a gap must be formed between the guide groove and the floating barrier, so that rainwater blocked by the floating barrier is formed through the gap between the guide groove and the floating barrier. There is a problem of leaking into the lowland. However, according to the present invention, by allowing the gap between the guide groove and the floating barrier to be sealed by the first sealing member, an advantageous effect of minimizing leakage of rainwater blocked by the floating barrier can be obtained.

The first sealing member may be formed in various structures capable of sealing a gap between the guide groove and the floating barrier. For example, when rainwater is blocked by the floating barrier, the first sealing member is pressed by the hydraulic pressure acting on the floating barrier and is closely contacted between the guide groove and the floating barrier. As another example, the first sealing member is selectively expanded and is configured to seal a gap between the guide groove and the floating barrier.

The rainwater blocking system also includes a second sealing member for sealing a gap between the trench and the floating barrier.

As such, by allowing the second sealing member to seal the gap between the trench and the floating barrier, an advantageous effect of minimizing the introduction of rainwater into the low water through the gap between the trench and the floating barrier can be obtained.

That is, the leakage of rainwater through the gap between the side end of the floating barrier and the guide groove may be sealed by the first sealing member, but the gap between the bottom of the floating barrier and the trench in the state where the floating barrier is supported inside the trench. Since the rainwater blocked by the floating barrier is formed through the gap between the lower end of the floating barrier and the trench, there is a problem that the low water flows into the lowland.

However, the present invention allows the gap between the trench and the floating barrier to be sealed by the second sealing portion, whereby the advantageous effect of minimizing the leakage of rainwater blocked by the floating barrier to the low land can be obtained.

In addition, a cover member is provided on the upper portion of the trench to cover the trench.

Thus, by arranging the cover member to cover the trench, it is possible to minimize the inflow of foreign matters into the trench, and to obtain an advantageous effect of preventing the damage of the floating barrier and the operation error (float error) caused by foreign matters. .

As described above, according to the present invention, it is possible to obtain an advantageous effect of effectively blocking the rainwater flowing into the lowland in the rainy weather.

That is, when rainwater rained down on the road in rainy weather rapidly enters the lowlands, rainwater flows back from the drainage of the road, and there is a problem that the road located in the lowlands floods quickly. In particular, when a vehicle is passing through a roadway (for example, an underground roadway), if rainwater falling on the road rapidly flows into a roadway located in a lowland area, there is a problem that a vehicle passing through the roadway is in danger.

However, the present invention is to arrange the floating barrier in the trench formed in the boundary region of the high and low land, and to float the floating barrier in response to the level of rainwater flowing into the trench, so that the rainwater rained down on the road during rainy weather from the high ground to the low land Since the inflow can be minimized, it is possible to obtain a beneficial effect of preventing damage to the lowlands by rainwater and improving the utilization and stability of the road.

In particular, according to the present invention can effectively block the rainwater flowing into the roadway located in the lowlands in the sidewalks located in the highlands, it is possible to obtain an advantageous effect of preventing the flooding of the roadway.

Further, according to the present invention, the floating barrier is lifted and operated in response to the level of rainwater flowing into the trench without using a separate power source, thereby obtaining an advantageous effect of simplifying the facility and facilitating maintenance and repair. Can be.

In other words, it is also possible to configure the floating barrier to be elevated by a drive source such as a motor. However, in order to install the motor in the trench into which rainwater flows, the waterproofing of the motor is required, and thus, the structure and the installation are complicated, and the cost of the facility increases. However, in the present invention, since the floating barrier can be operated without power without using a driving source such as a motor, the structure and installation are easy, maintenance and repair are very easy, and the advantageous effect of lowering the equipment cost can be obtained. .

In addition, according to the present invention it is possible to prevent the damage of the lowlands by rainwater, and to obtain an advantageous effect of improving the utilization and stability of the road. Therefore, the stability and reliability of the tunnel can be improved.

1 to 11, a rainwater blocking system that blocks rainwater (RW) flowing into the lowland 110 from the highland 120 is recessed in the boundary region BZ of the highland 120 and the lowland 110. Floating barrier that selectively floats in response to the formed trench 101 and the level of rainwater RW flowing into the trench 101 and blocks rainwater RW from entering the lowland 110 from the highland 120. 200.

For reference, in the present invention, the lowland 110 may be understood as a concept including all roads and areas located at a relatively lower height than the highland 120, and by the type and location of the lowland 110 The present invention is not limited or limited. Hereinafter, the highlands 120 are sidewalks for pedestrians to walk, and the lowlands 110 will be described with an example of a roadway (for example, an underground roadway) through which vehicles pass.

The trench 101 is recessed in the boundary region BZ of the highland 120 and the lowland 110, and the floating barrier 200 is selectively accommodated in the trench 101.

Here, the boundary region BZ of the highlands 120 and the lowlands 110 is defined as an area connecting the highlands 120 and the lowlands 110 and is viewed by the size and position of the boundary zone BZ. The invention is not limited or limited. For example, the boundary area BZ is formed to be inclined between the highlands 120 and the lowlands 110.

The trench 101 may be formed in various structures in which the floating barrier 200 may be accommodated to move in the vertical direction.

For example, the trench 101 may be formed in the boundary region BZ of the highland 120 and the lowland 110 along a direction perpendicular to the ground. According to another embodiment of the present invention, the trench may be formed to be inclined with respect to the direction perpendicular to the ground, or may be formed in a curved shape.

In addition, referring to FIG. 1, a cover member 103 is provided on the trench 101 to cover the trench 101.

As such, by arranging the cover member 103 to cover the trench 101, the foreign matter may be minimized from entering the trench 101, and the floating barrier 200 may be damaged and operate due to the foreign matter. Advantageous effect of preventing flotation errors).

In rainy weather, the cover member 103 may be removed from the trench 101, and the upper portion of the trench 101 is opened by removing the cover member 103. In some cases, the cover member removed from the trench may be stored in a folded or curled state at one end of the trench.

The floating barrier 200 is accommodated in the trench 101 to selectively float in response to the level of the rainwater RW flowing into the trench 101, and the rainwater RW is a low land 110 in the highlands 120. It is provided to block the inflow to).

Here, the blocking barrier 200 blocks the rainwater (RW) flowing into the lowlands 110 from the highlands 120, the rainwater (RW) that rained during the rain flows from the highlands 120 to the lowlands 110. It is defined as blocking.

More specifically, the floating barrier 200 may be selectively floated according to the level of rainwater RW flowing into the trench 101, and at the standby position accommodated in the trench 101, to the outside of the trench 101. Move to the protruding blocking position.

In the standby position, the floating barrier 200 is completely received inside the trench 101 without protruding out of the trench 101.

On the other hand, in the blocking position, the floating barrier 200 is disposed to protrude to the upper portion of the trench 101 while being supported by rainwater RW. When the floating barrier 200 is disposed at the blocking position, a blocking wall is formed to block rainwater RW as the floating barrier 200 protrudes upward of the trench 101, and the rainwater flowing down from the altitude 120 is formed. RW) is blocked by the floating barrier 200 without flowing down into the low zone 110.

The structure and shape of the floating barrier 200 may be variously changed according to the required conditions and design specifications.

For example, the floating barrier 200 may be formed in a plate shape and selectively lifted in response to the level of rainwater RW flowing into the trench 101.

Preferably, referring to Figure 3, the floating barrier 200 is formed in a shape having a cross-sectional area gradually expanded from the top to the bottom. More preferably, the floating barrier 200 is formed in the shape of a trapezoid (isosceles trapezoid) cross section having the same size of the two base angles and the same length of the two diagonals.

As such, by forming the lower width W2 of the floating barrier 200 larger than the upper width W1, the water pressure P by the rainwater RW in the state where the floating barrier 200 is raised to the blocking position. Withstand more stably, it is possible to obtain an advantageous effect of minimizing deformation and breakage due to water pressure (P).

That is, since the hydraulic pressure P acting on the floating barrier 200 in the state in which the floating barrier 200 is raised to the blocking position increases toward the lower portion of the floating barrier 200, the lower end of the floating barrier 200 is lower than the upper end. By forming in a form having an expanded cross-sectional area, the water pressure P due to the rainwater RW can be more stably held without deformation and breakage.

The floating barrier 200 may be formed of a material that can float on rainwater (RW), for example, a material such as plastic or wood, and the present invention is not limited or limited by the material of the floating barrier 200. .

In addition, the floating barrier 200 may be formed of a material and a structure capable of supporting the rainwater RW as a whole, but in some cases, a material or structure capable of supporting only a portion of the floating barrier in the rainwater (eg, air Chamber).

In addition, the rain water blocking system includes a connection passage 210 for connecting the trench 101 and the low zone 110, and the opening and closing valve 212 to selectively open and close the connection passage 210.

More specifically, when the open / close valve 212 blocks the connection passage 210, the floating barrier 200 is supported by the rainwater RW introduced into the trench 101. On the contrary, when the open / close valve 212 opens the connection passage 210, the rainwater RW introduced into the trench 101 is drained through the drain passage (not shown) of the low zone 110 through the connection passage 210. do.

Referring to FIG. 2, as the level of the rainwater RW introduced into the trench 101 increases in the state in which the connection passage 210 is blocked, the floating barrier 200 has a higher lifting height. On the other hand, referring to FIG. 5, when the connection passage 210 is opened, the rainwater RW introduced into the trench 101 is drained through the low passage 110 through the connection passage 210 and flows into the trench 101. As the level of the rainwater RW is lowered, the flotation height of the floating barrier 200 is gradually lowered.

As the open / close valve 212, a conventional valve capable of selectively opening and closing the connection passage 210 may be used, and the present invention is not limited or limited by the type and structure of the open / close valve 212.

In addition, the opening and closing valve 212 may be configured to be opened or closed manually by a manual operation of the operator, or automatically opened and closed by a remote operation.

The opening / closing time of the on / off valve 212 may be variously changed according to a required condition and a use environment. For example, the opening and closing valve 212 may be configured to block the connection passage 210 in rain weather and open the connection passage 210 in fine weather.

The rainwater blocking system also includes a stopper 220 that constrains the floating barrier 200 to float above the reference flotation height range.

The stopper 220 may be formed in various structures capable of restraining the floating barrier 200 from being floated beyond the reference lift height range.

For example, the stopper 220 is formed to protrude in the form of a protrusion on the inner wall surface of the trench 101, and when the floating barrier 200 is supported in the reference lifting height range, the stopper 220 on the outer surface of the floating barrier 200 Contact and constrain the floating barrier 200. Preferably, at least one pair of stoppers 220 is provided to face each other with the floating barrier 200 therebetween. In some cases, the stopper 220 may be formed in a continuous ring shape along the inner wall of the trench.

Referring to FIG. 1, in a state in which the floating barrier 200 is disposed at a standby position, the stopper 220 is disposed to be spaced apart from an outer surface of the floating barrier 200. On the other hand, referring to Figure 3, in the state in which the floating barrier 200 is supported to the blocking position, the additional support of the floating barrier 200 is suppressed by restraining the stopper 220 on the outer surface of the floating barrier 200.

In the above-described and illustrated embodiments of the present invention, the floating barrier 200 has a trapezoidal shape. For example, the floating barrier 200 may have the same width as the upper and lower ends of the floating barrier. Do.

Referring to FIG. 4, the floating barrier 200 ′ is formed to have the same width W at the top and the bottom thereof, and a locking protrusion 201 ′ at which the stopper 220 is constrained is formed at the bottom of the floating barrier 200. Is formed to protrude. In the state where the floating barrier 200 'is lifted to the blocking position, the stopping protrusion 201' is restrained by the stopper 220, thereby further restraining the floating barrier 200 '.

In addition, the rainwater blocking system includes a guide part 300 for guiding the vertical movement of the floating barrier 200 with respect to the trench 101.

As described above, the guide part 300 guides the vertical movement of the floating barrier 200 with respect to the trench 101, thereby suppressing abnormal flow of the floating barrier 200, and the attitude of the floating barrier 200. It is possible to obtain an advantageous effect of keeping the stable.

The guide part 300 may be formed in various structures capable of guiding the vertical movement of the floating barrier 200 with respect to the trench 101. For example, referring to FIGS. 6 and 7, the guide parts 300 are provided at both ends of the trench 101, and the guides having a substantially “U” shape along the up and down directions are provided on the inner wall surface of the guide part 300. The groove 310 is recessed and the end of the floating barrier 200 (eg, one end, the other end and at least one or more) is movably received along the guide groove 310 in the guide groove 310.

The end of the floating barrier 200 linearly moves along the guide groove 310 in a state accommodated in the guide groove 310.

For reference, in the embodiment of the present invention, the guide groove 310 is formed on the inner wall surface of the guide portion 300, the end of the floating barrier 200 has been described with an example that is accommodated in the guide groove 310, According to another embodiment of the present invention, it is also possible to form a guide groove at the end of the floating barrier, and to form a guide protrusion accommodated in the guide groove on the inner wall surface of the guide portion.

As described above, in the present invention, the floating barrier 200 is disposed in the trench 101 formed in the boundary region BZ of the highlands 120 and the lowlands 110, and the water level of the rainwater RW flowing into the trench 101 is provided. By allowing the floating barrier 200 to float in response to rain, the rainwater (RW) that falls on the road during rainy weather can be minimized from entering the lowland 110 from the highlands 120, and thus, the lowland due to the rainwater (RW) It is possible to obtain an advantageous effect of preventing damage to the 110 and improving the utilization and stability of the road.

Above all, the present invention simplifies, maintains and maintains the facility by allowing the floating barrier 200 to move up and down in response to the level of rainwater RW flowing into the trench 101 without using a separate power source. An advantageous effect of facilitating repair can be obtained.

In other words, it is also possible to configure the floating barrier to be elevated by a drive source such as a motor. However, in order to mount the motor in the trench into which rainwater flows, the waterproofing of the motor is required, and thus, the structure and the installation are complicated, and the facility cost increases. However, in the present invention, since the floating barrier 200 can be automatically operated by buoyancy in a non-powered manner without using a driving source such as a motor, not only the structure and installation are easy but also the maintenance and repair are very easy, The beneficial effect of lowering the cost can be obtained.

In addition, the rainwater blocking system includes a first sealing member 230 for sealing a gap between the guide groove 310 and the floating barrier 200.

In this way, by allowing the first sealing member 230 to seal the gap between the guide groove 310 and the floating barrier 200, the rain water (through the gap between the guide groove 310 and the floating barrier 200) RW) may be advantageous to minimize the inflow into the low zone (110).

That is, in order to prevent the flooding of the low land zone 110 in rainy weather, the leakage of rainwater RW should be minimized while the floating barrier 200 is raised to the blocking position.

However, in order to ensure the vertical movement (support) of the floating barrier 200 in the trench 101, a gap must be formed between the guide groove 310 and the floating barrier 200, so that the floating barrier 200 Rainwater (RW) blocked by the leakage is leaked through the gap between the guide groove 310 and the floating barrier 200 is introduced into the low zone (110).

However, in the present invention, the gap between the guide groove 310 and the floating barrier 200 is sealed by the first sealing member 230, whereby rainwater RW blocked by the floating barrier 200 leaks. The beneficial effect of minimizing the like can be obtained.

The first sealing member 230 may be formed in various structures capable of sealing a gap between the guide groove 310 and the floating barrier 200.

For example, referring to FIG. 7, when the rain water RW is blocked by the floating barrier 200, the first sealing member 230 is pressurized by the hydraulic pressure P acting on the floating barrier 200 to guide the groove. It is in close contact between the 310 and the floating barrier 200.

More specifically, the first sealing member 230 is formed to be pressed into the guide groove 310 by the floating barrier 200 acting the hydraulic pressure (P). That is, the water pressure (P) by the rain water (RW) acts on one surface (surface facing the high ground) of the floating barrier 200, the other surface of the floating barrier 200 is disposed to face the guide groove 310, The first sealing member 230 is formed on the other surface (the surface facing the basin) of the floating barrier 200 to face the guide groove 310. Preferably, the first sealing member 230 is continuously formed on the other surface of the floating barrier 200 along the guide groove 310. According to another embodiment of the present invention, it is also possible to form the first sealing member on the inner wall surface of the guide groove facing the floating barrier.

The first sealing member 230 may be formed of a rubber or silicon material elastically compressible between the other surface of the floating barrier 200 and the guide groove 310, the material of the first sealing member 230 is required Various changes may be made depending on the conditions and design specifications.

As such, the first sealing member 230 is in close contact with the hydraulic pressure P acting on the floating barrier 200 and seals the gap between the guide groove 310 and the floating barrier 200. An advantageous effect of increasing the sealing efficiency of the sealing member 230 and more effectively blocking the leakage of the rain water RW can be obtained.

As another example, referring to FIG. 8, the first sealing member 230 ′ is selectively expanded and may be configured to seal a gap between the guide groove 310 and the floating barrier 200.

The first sealing member 230 ′ may be configured to expand in a balloon-like manner when a gas (or fluid) is injected, and the present invention is limited or limited by the expansion method of the first sealing member 230 ′. no.

For example, a cylinder (not shown) in which compressed gas (for example, carbon dioxide) is stored is connected to the first sealing member 230 ′, and the compressed gas is compressed from the cylinder by a manual operation or a remote control of a user. When supplied to 230 ′, the first sealing member 230 ′ expands momentarily and seals a gap between the guide groove 310 and the floating barrier 200.

In this case, since the first sealing member 230 ′ is expanded by the compressed gas, even if the first sealing member 230 ′ is disposed at the side end portion of the floating barrier 200, sufficient sealing performance may be exhibited. In some cases, it is also possible to arrange the expanding first sealing member on the other surface of the floating barrier facing the guide groove.

In addition, referring to FIG. 9, the rainwater blocking system according to the present invention includes a second sealing member 240 for sealing a gap between the trench 101 and the floating barrier 200.

As described above, the second sealing member 240 seals the gap between the trench 101 and the floating barrier 200, thereby causing rainwater RW through the gap between the trench 101 and the floating barrier 200. An advantageous effect of minimizing the introduction into the low zone 110 can be obtained.

That is, the leakage of rain water RW1 through the gap between the side end of the floating barrier 200 and the guide groove 310 may be sealed by the first sealing member 230, but the floating barrier 200 may be formed in the trench 101. Since a gap is formed between the lower end of the floating barrier 200 and the trench 101 in the state of being floated inside), the rain water RW blocked by the floating barrier 200 is lower than the lower end of the floating barrier 200. There is a problem that the leakage (RW2) through the gap between the trench 101 is introduced into the low zone (110).

However, according to the present invention, the gap between the trench 101 and the floating barrier 200 is sealed by the second sealing member 240, so that the rainwater RW blocked by the floating barrier 200 is lowered. A beneficial effect of minimizing leakage to 110 can be obtained.

The second sealing member 240 may be formed in various structures capable of sealing a gap between the trench 101 and the floating barrier 200.

For example, referring to FIG. 9, when the rain water RW is blocked by the floating barrier 200, the second sealing member 240 is pressed by the water pressure P acting on the floating barrier 200 and the trench ( It is in close contact between the inner wall surface of the 101 and the floating barrier 200.

More specifically, the second sealing member 240 is formed to be pressed to the inner wall surface of the trench 101 by the floating barrier 200 acting the hydraulic pressure (P). That is, the water pressure P by rain water RW acts on one surface (surface facing the high ground) of the floating barrier 200, but the second sealing member 240 floats to face the inner wall surface of the trench 101. It is formed on the other surface of the barrier 200 (surface facing a basin). Preferably, the second sealing member 240 is continuously formed on the other surface of the floating barrier 200 along the horizontal length direction of the floating barrier 200.

Preferably, the second sealing member 240 is formed to have a thickness thicker than the first sealing member 230, the second when the water pressure (P) by the rain water (RW) acts on one surface of the floating barrier 200, While the sealing member 240 is in close contact with the inner wall of the trench 101, the first sealing member 230 is configured to be in close contact with the inner wall of the guide groove 310.

Further, according to another embodiment of the present invention, it is also possible to form the second sealing member on the inner wall surface of the trench facing the other surface of the floating barrier.

The second sealing member 240 may be formed of a rubber or silicon material elastically compressible between the other surface of the floating barrier 200 and the trench 101, the material of the second sealing member 240 is required Various changes may be made depending on conditions and design specifications.

As described above, the second sealing member 240 is brought into close contact with the hydraulic pressure P acting on the floating barrier 200 and seals the gap between the trench 101 and the floating barrier 200. An advantageous effect of increasing the sealing efficiency of the member 240 and more effectively blocking the leakage of the rain water RW can be obtained.

According to another embodiment of the present invention, it is also possible to configure the second sealing member to expand selectively and to seal the gap between the trench 101 and the floating barrier 200.

In the above-described and illustrated embodiments of the present invention, the rainwater flowing into the lowland from the highlands is blocked by only one floating barrier, but in some cases, the rainwater flowing into the lowland from the highlands is provided with a plurality of floating barriers. It is also possible to configure to be blocked by.

For example, referring to FIG. 10, a plurality of trenches 101 are formed to be spaced apart at predetermined intervals along one direction in an area where rain water is required to be blocked, and a plurality of floating barriers 200 are formed in each trench 101. It is selectively supported in response to the level of the incoming rainwater (RW) and blocks the rainwater (RW) from entering the lowlands in the highlands 120.

The vertical movement of each floating barrier 200 is individually guided by the plurality of guide parts 300. For example, a guide groove 310 having a substantially “U” shape is recessed in an up and down direction on an inner wall of the guide part 300, and an end of the floating barrier 200 is formed in the guide groove 310. It is received to be movable along 310.

Preferably, the plurality of guide parts 300 are formed in the form of pillars protruding from the ground, and the guide parts 300 adjacent to each other are arranged to be in close contact with each other so that the guide grooves 310 face in opposite directions to each other. For example, the first guide groove of the first guide part that guides the right end of the first floating barrier is formed to face the left direction, and the first guide groove that guides the left end of the second floating barrier disposed on the right side of the first floating barrier. The second guide groove of the second guide portion is formed to face in the right direction, and the first guide portion and the second guide portion are disposed to closely contact each other between the first floating barrier and the second floating barrier.

As described above, the plurality of guide parts 300 are formed to protrude from the ground, and the guide parts 300 adjacent to each other are brought into close contact with each other, so that the plurality of floating barriers 200 are supported by rain water. Since the gap between the floating barriers 200 may be blocked by the guide unit 300, the rainwater barrier walls are continuously connected in series using the plurality of guide units 300 and the plurality of floating barriers 200. It is possible to do

At this time, the leakage of rainwater through the gap between the side end of each floating barrier 200 and each guide groove 310 may be sealed by the first sealing member 230. Similarly, leakage of rainwater through the gap between the bottom of each floating barrier 200 and the trench 101 may be sealed by a second sealing member (see 240 in FIG. 9).

In addition, the rainwater blocking system according to the present invention can be mounted inside the tunnel.

Referring to FIG. 11, a walkway that a pedestrian walks inside the tunnel is disposed on the altitude 120 relatively than the roadway through which the vehicle passes (the lowland 110), and the floating barrier 200 is an altitude 120 (walkway) 120. It is provided so as to selectively float between the low and low (road) 110, and the rainwater (RW) introduced into the tunnel blocks the flow down from the high (120) road to the low (road) (110).

As described above, although described with reference to a preferred embodiment of the present invention, those skilled in the art will be variously modified and modified within the scope of the present invention without departing from the spirit and scope of the present invention described in the claims below. It will be appreciated that it can be changed.
