DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a parking lot device which adjusts a flow rate of rainwater downstream of a river or a drainage channel and also serves as a retarding pond used as a parking lot.

[0002]

2. Description of the Related Art In recent years, in a development area, for example, an underground type reservoir or a dug type retarding reservoir has been known as a retarding reservoir for adjusting the flow rate of rainwater downstream of a river or a drainage channel. Have been.

[0003] However, the former underground type retarding basin device has not been widely adopted in a development area where a small retarding basin in which housing complexes, condominiums, etc. are lined up is economically burdensome. In such development areas, the latter dug-type ponds are mainly used.

[0004] Heretofore, conventionally, in the case of a digging-type retarding basin device, for example, when rainwater flows into a water storage tank of the retarding basin device during rainfall, the rainwater is temporarily stored and is downstream. The rainwater flow is adjusted.

[0005] However, for example, when rainwater is not stored in the water storage tank, a large space in the water storage tank is wasted.

[0006] Therefore, for example, a park or a tennis court is provided in the water storage tank, and the space in the water storage tank is effectively used.

[0007] On the other hand, in a development area where apartment complexes, condominiums, and the like are lined up, a shortage of parking lots has become a serious problem.

[0008]

However, it is conceivable that the inside of the reservoir of the conventional dug-type retarding basin device is used as it is as a parking lot. For example, when a heavy rainfall occurs, a large amount of rainwater is stored in the reservoir. If it flows into the tank,
There is a problem that a vehicle placed in a parking lot is submerged.

On the other hand, a large number of crushed stones are filled in a water tank of a conventional dug-type retarding basin device so that each crushed stone has a gap, and a parking lot is placed on the water tank, that is, on the large number of crushed stones. However, in such a retarding pond device, for example, the porosity between each crushed stone is low, so the water storage rate of the water storage tank is low, and the clogging between each crushed stone is likely to occur, so that maintenance is required. There is a problem that is complicated.

The present invention has been made in view of the above points, and can prevent the vehicle from being submerged, improve the use of an effective space in a water storage tank, and can manufacture the apparatus at low cost, and can maintain the apparatus at low cost. It is an object of the present invention to provide a simple parking lot device that also serves as a retarding pond.

[0011]

According to a first aspect of the present invention, there is provided a parking lot device serving also as a retarding basin, comprising a water storage tank and a floating plate floating by rainwater flowing into the water storage tank.

When the rainwater flows into the water storage tank, the rainwater is stored in the water storage tank, so that the flow rate of the rainwater downstream of a river, a drain, or the like is adjusted.

Further, since the floating board floats by rainwater flowing into the water storage tank, the vehicle mounted on the upper surface of the floating board is prevented from being submerged.

According to a second aspect of the present invention, there is provided a parking lot device which also serves as a detention basin, wherein the floating plate is formed by a plurality of blocks connected to each other. Things.

Since the levitation board is formed of a plurality of blocks connected to each other, the levitation board can be easily installed in a wide water storage tank.

According to a third aspect of the present invention, there is provided a parking lot apparatus which also serves as a detention pond according to the first or second aspect, wherein a passage end provided at an edge of the water storage tank and a floating plate are provided. The bridge is connected to the upper surface and has a bridge body on which the vehicle can travel.

[0017] Since the bridge end connects the passage end at the edge of the water storage tank and the upper surface of the floating disk, the floating disk is not above the ground surface when rainwater is not stored in the water storage tank. Even at a low position, the vehicle can be easily taken in and out.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a parking lot according to the present invention.

In FIG. 1 to FIG. 3, reference numeral 1 denotes a water storage tank. The water storage tank 1 is formed by digging a ground surface 2 and providing a not-shown burble foundation on the bottom surface. The bottom plate 3 is laid and the side plates 4, 5, and 6 are erected by ready-mixed concrete with on-site concrete, thereby forming a substantially box shape with an open upper surface.

The bottom plate 3 of the water storage tank 1 allows the rainwater flowing into the water storage tank 1 to flow from one side (the right side in FIGS. 1 to 3) to the other side (the left side in FIGS. 1 to 3). It is laid with a slight inclination toward the other side downward. Also,
The other end of the bottom plate 3 is provided with a water guide groove 9 which is slightly inclined forward and downward so as to guide rainwater flowing into the other side to the front side on the other side (FIG. 3).

Further, a discharge pipe 10 for discharging rainwater flowing into the front side to a river (not shown), a drainage channel or the like outside the water storage tank 1 is connected to a downstream end portion on the front side of the water guide groove 9.

The upper surfaces of the side plates 4, 5, and 6 of the water storage tank 1 are located on the same plane as the ground surface 2, respectively. In the vicinity, as shown in FIG. 3, a passage end 12 such as a road paved with asphalt is located.

Further, for example, on the upper part of one side plate 5,
An inflow pipe (not shown) for guiding rainwater into the water storage tank 1 is connected.

In the water storage tank 1, a floating board 14 which floats by the rainwater flowing into the water storage tank 1 is installed vertically movably over the entire upper surface of the bottom plate 3. The upper surface of the floating board 14 is formed to be substantially smooth, and the vehicle 15 can be appropriately mounted and parked on the upper surface of the floating board 14.

The vehicle 15 is moved into and out of the floating board 14 using a bridge 16 that connects the upper surface of the floating board 14 and the passage end 12 located at the edge of the water storage tank 1. Even when the floating board 14 is at the lower position in the water tank 1, the bridge body 16 moves vertically upward due to the buoyancy from the rainwater and is at the upper position in the water tank 1. Even in such a case, the vehicle 15 can run on it.

Further, the floating board 14 is formed of a plurality of blocks 18 and a plurality of connection fittings 31. First, each block 18 has a square cross section and a lower section as shown in FIGS. A substantially decahedral shape with a cutout side, that is, an upper surface 21
With a smaller underside 22 and each top base is a vertical side
Each of the lower bases forms a substantially trapezoidal shape forming one side of the lower surface 22, and has a substantially decahedral shape having an inclined side surface 24 sloping from the lower surface side to the upper surface side.

Each of these blocks 18 is made of, for example, expanded polystyrene (foamed polystyrene) obtained by blending a foaming agent such as butane, pentane, or hexane with a styrene resin and heating and foaming the same. A main part 25 formed into a shape, and a fiber-reinforced concrete or a fiber-reinforced composite material (FRP, FRM), which is a concrete containing fibers of metal, mineral or organic material, is covered with the main part 25 around the main part 25. , FRR), and a coating portion 26 formed into a thin shape with an organic material such as polyethylene and polyvinyl chloride, and a metal material such as stainless steel.

Further, the adjacent blocks 18 are connected to each other by the plurality of connection fittings 31 so that a gap 33 is formed between the vertical side surfaces 23 of the adjacent blocks 18.

These connecting fittings 31 are shown in FIGS.
As shown in FIG. 5, for example, four hook bodies 36 made of a metal material and formed into a shape in which an intermediate portion is bent at an acute angle, and one ring body 37 also made of a metal material in a ring shape
Are provided as a set.

The base end of each of the hooks 36 is attached to a hook support 38 fixed to the end of the inclined surface 24 of the block 18, and the four hooks 36 facing each other are connected to the hooks 36. Each of the adjacent blocks 18 is securely connected to each other by being hooked on one ring body 37 and being hooked on the intermediate portion 35 of each hook body 36.

Next, the operation of the above embodiment will be described.

For example, when rainwater is not stored in the water storage tank 1 when the weather is fine, the floating plate 14 is attached to the water storage tank 1.
Located in the lower part of the inside, this water storage tank 1 is used as a parking lot. In addition, putting the vehicle 15 in and out of this parking lot,
As shown in FIG. 2, this is performed using a bridge body 16.

In a state where the vehicle 15 is mounted and parked on the upper surface of the floating board 14, for example, in the case of a small rainfall shown in FIG. When the rainwater flows into the water storage tank 1 through an inflow pipe (not shown), the rainwater flows into the bottom plate 3 of the water storage tank 1.
After flowing from one side to the other side between the block 18 and the other side, and flowing in the water guide groove 9, the water is discharged from the discharge pipe 10 to a river, a drainage channel, or the like. At this time, the floating board 14 in the water storage tank 1 does not move from the state located on the lower side.

However, for example, in the case of a heavy rainfall shown in FIG. 1, a large amount of rainwater passes through the gap 33 between the vertical side surfaces 23 of each block 18 and the inflow pipe (not shown), and Since the water flows into the water, there is a limit to the flow rate of the rainwater discharged from the discharge pipe 10, and the flowed rainwater is temporarily stored in the water storage tank 1, and the flow rate of the rainwater downstream of a river, a drainage channel, or the like. Is adjusted.

At this time, the floating plate 14 located on the lower side of the water storage tank 1 removes rainwater stored in the water storage tank 1 regardless of whether the vehicle 15 is mounted on the upper surface thereof. It moves vertically upward due to the buoyancy it receives.

Therefore, even when the inside of the water storage tank 1 functions as a retarding basin, the floating board 14 is located above the water storage tank 1 and the vehicle 15 mounted on the upper surface of the floating board 14 is submerged. There is no.

Further, even when the floating board 14 is positioned above the water storage tank 1, the vehicle 15 can be put in and out of the parking lot by using the bridge 16 as shown in FIG. .

Further, as the amount of rainwater stored in the water storage tank 1 decreases, the floating board 14 gradually moves vertically downward due to its own gravity and the force received from the vehicle 15.

As described above, according to the embodiment of the parking lot device also serving as the retarding pond, in a state where the rainwater is stored in the water storage tank 1 in order to adjust the flow rate of the rainwater downstream. Regardless of whether or not the vehicle 15 is mounted on the upper surface of the levitator 14, the levitator 14 floats due to the rainwater in the water storage tank 1, so that the vehicle 15 mounted on the upper surface of the levitator 14 is submerged. In addition, in a state where the floating board 14 is floated by the rainwater in the water storage tank 1, for example, even when a plurality of vehicles 15 are mounted on only one side of the floating board 14, There is no danger that the levitation board 14 will tilt greatly,
The water storage tank 1 can be used as a parking lot, and the availability of an effective space in the water storage tank 1 is improved.

In addition, this parking lot device which also serves as a retarding pond,
It is a digging type retarding basin device, and its configuration is simple, so it can be manufactured at low cost and maintenance is simple.

Further, the plurality of blocks 18 included in the floating board 14 are respectively composed of a main part 25 formed of styrene foam having a relatively small specific weight and a covering part 26 formed of fiber reinforced concrete. As a result, the levitation from the rainwater causes the levitation board to float reliably, and the vehicle 15 mounted on the upper surface of the levitation board 14 can be reliably prevented from submerging,
In the covering portion 26, the durability of each block 18 is improved.

The floating board 14 is provided with a plurality of connecting fittings 31.
Since it is formed of a plurality of blocks 18 connected to each other, the respective blocks 18 are appropriately arranged according to the size, shape, etc. of the required retarding ponds, and The floating board 14 can be easily installed only by connecting with the connecting metal fittings 31, and the workability is good.

Further, the connecting fitting 31 has a hook body 36 and a ring body 37, and the adjacent blocks 18 are securely connected to each other by the hook body 36 being engaged with the ring body 37. In a state in which the floating plate 14 is located on the upper side in the water tank 1, between the block 18 on which the vehicle 15 is mounted on the upper surface 21 and the block 18 on which the vehicle 15 is not mounted on the upper surface 21. There is no large step. Therefore, even when the levitating plate 14 is in the upper position, the vehicle 15 can smoothly travel on the upper surface of the levitating plate 14.

Since the bridge body 16 connects the passage end 12 at the edge of the water storage tank 1 and the upper surface of the floating plate 14, the floating plate 14
Regardless of the vertical position of the vehicle, the vehicle 15 can run smoothly on the upper surface of the levitating plate 14, and the vehicle 15 can be easily taken in and out, further improving the utilization of the effective space in the water storage tank 1. Is achieved.

In the above-described embodiment, a description has been given of a configuration in which the floating board 14 is formed by a plurality of substantially decahedral blocks 18. However, the block 18 is not limited to this shape. For example, the floating board 14 may be formed by one or two or more flat blocks.

In the above description, the plurality of blocks 18 have the main part 25 formed of styrofoam and the covering part 26 formed of fiber reinforced concrete. For example, the blocks 18 are formed of styrofoam. A configuration having only the main portion 25 or a configuration having only the covering portion 26 formed of fiber-reinforced concrete or the like may be employed.

Further, in the above-described embodiment, the description has been given of the configuration in which the floating board 14 is formed by the block 18 and the connection fitting 31, but the connection fitting 31 is not always required. When the floating board 14 is constituted by only the blocks 18, the floating board 14 can be easily installed and the workability can be improved simply by appropriately arranging the blocks 18.

Further, in the above-described embodiment, the structure including the bridge body 16 has been described.
It is not necessary to provide.

In the above embodiment, the vehicle
Although the case where the vehicle 15 is parked on the upper surface of the floating board 14 to prevent the vehicle 15 from being submerged has been described, the vehicle 15 includes a motorcycle, a bicycle, and the like.
