Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a water storage facility provided in a waterway.

[0002]

2. Description of the Related Art Waterways including rivers, canals, and the like have a relatively low water level in normal times when rain falls on average, and the waterways have sufficient capacity. However, once the heavy rainfall has caused the water channel to rise, the situation may change completely. For example, waterways flowing in rural areas are relatively wide and both banks of the waterways are often provided with sloping banks or dikes, so even if the waterways increase, there is not enough water capacity. There is. However, in urban areas, widening of the waterway is often restricted in terms of location. In such an area, the width of the waterway is relatively narrow and there is no room for water capacity. For this reason, when the water channel increases, water may overflow from the water channel.

[0003]

In a waterway flowing through an urban area having a large population density as described above, when a large amount of rain falls due to abnormal weather or the like, or when a natural or artificial unexpected cause causes the waterway to be closed. If the flowing water increases, the increased water may overflow from the water channel. Therefore, it is necessary to give sufficient consideration to rising water levels in waterways flowing through urban areas. In addition, if rainwater is considered as one of the resources, it can be said that draining rainwater that has fallen downward without using it beneficially is a waste of resources.

[0004] It is an object of the present invention to secure a space in which water is stored when a water channel increases.

[0005]

In order to solve the above-mentioned problems, the present invention is characterized in that storage means capable of storing water is provided on a water channel. In this way, for example, a lot of rain falls due to abnormal weather, etc., and the waterway increases,
Or when the waterway overflows due to other natural or artificial unforeseen causes and the water overflows the waterway, the water is stored in the storage means provided above the waterway, and the water in the waterway overflows. To prevent In addition, since the storage means is provided on the water channel, it is hardly restricted by location and space, and a space for storing water can be secured.

[0006] The lower surface of the storage means may be open to the water channel, or a water-blocking member may be provided to separate the water storage space of the storage means from the upper space of the water channel. When the lower surface of the storage means opens into the water channel, the increased water in the water channel directly flows into the storage space of the storage means. When the space of the storage means and the upper space of the waterway are separated, a means for transferring the increased water in the waterway may be provided so that the overflowing water can be transferred to the storage means. Further, the storage means may include a structure having a space capable of storing water, and a water-blocking member that covers the structure. In this case, since the structure is covered with the water blocking member, the water in the increased water channel flows into the space of the structure, and the increased water can be stored.

Further, another structure may be provided outside the water blocking member. Thus, when the water is stored in the structure, the pressure of the stored water is applied to the water-blocking member that covers the side surface of the structure. This pressure can be received by another structure provided outside the water blocking member. In this case, it is preferable that another structure receives the pressure applied to the water-blocking member on its surface.
Receiving on the surface prevents breakage of the water shielding member.
In addition, since it is preferable that another structure has a large weight,
It is preferable to increase the weight of the structure by filling a filler such as soil and sand.

Further, it is preferable that a plurality of storage means are provided along the water channel. With this configuration, since the water channel has a gradient in the direction in which the water flows, the installation height of the storage means can be sequentially changed along the direction in which the water flows. Since the storage means is provided at different installation heights, it is possible to prevent the stored water from being biased. Since the bias of the water can be prevented, the capacity storage efficiency of the water can be increased. Further, the water stored in each storage means can be used systematically and elastically according to the purpose of use.

Furthermore, the structure is preferably formed by connecting a plurality of structural members. In this case, the shape can be elastically formed according to the location and conditions where the water storage facility is provided. Further, even after the storage means is installed, the height and width thereof can be changed to change the capacity for storing water. Further, since the weight of each structural member is small, it can be easily transported and handled. Further, since the structure is assembled by connecting a plurality of structural members, no skill is required and the construction period is shortened.

Further, the structural member is preferably formed of a lightweight material. As a material of the structural member, a synthetic resin such as polypropylene, a light metal such as an aluminum alloy, a lightweight concrete, or the like is used. In particular, a material having corrosion resistance to water is used. Since the structural member is formed of a lightweight material, the weight is reduced and the assembling workability is improved.

The structural member has a base having a flat surface on one side, and legs extending to the other side of the base. It is better to connect them facing each other. A space is formed between the legs.
A structure in a stable state is formed by connecting flat surfaces so as to face each other.

Next, the requirements constituting the present invention will be described in more detail. Waterways include rivers and canals. The storage means is not particularly limited as long as it has a space in which water can be stored, but the entirety is formed by integrally connecting one or several sub-structures, or by connecting structural members that are unit members. Can be assembled.

[0013] The structural member can be formed into an appropriate shape as long as it has the required strength and rigidity, but has a space that communicates with the outside. Water can be stored in this space. The water-blocking member is not particularly limited as long as it can block water. The water-blocking member may be a plate, a sheet, or the like, and may be made of a corrosion-resistant metal, synthetic resin, or the like. For example, a synthetic rubber sheet may be used. It is preferable to provide a protective material such as a sheet mainly composed of polyester single fiber between the water blocking member and the structure. The protective material protects the water shielding member.

Another structure may be the same as the structure forming the storage means, or may be a structure having a different structure. When the structure is formed by connecting the structural members, the shape of the structural member can be a frame, a container, or a shape in which legs are extended on the previous base.
