Field of the Invention The present invention relates to a distribution pipe for securing emergency drinking water, living water and fire protection water in the event of a disaster such as an earthquake. The present invention relates to an emergency water storage tank device provided with a plurality of divided water storage tanks installed in a storage tank. 2. Description of the Related Art When a large-scale earthquake occurs and a normal water supply and distribution system loses its function, it is urgently necessary to secure drinking water.
As is evident from past damage cases, water cutoff occurs due to breakage of water supply and distribution pipelines. For this reason, local governments have taken measures such as installing emergency water storage tanks in various places in advance. As the emergency water storage tank, an earthquake-resistant water storage tank having a small size of several tens tons and a large size of several hundred tons has been developed. Such water tanks are often buried underground or stand alone on the ground. A water storage tank that injects water into the water tank and simply stores the water in case of an emergency is not suitable for drinking water because it rots due to water stagnation, and plays a large role as fire protection water. Even if the water in the water storage tank is frequently replaced or the water is circulated, deterioration of the water quality is inevitable. [0003] For this reason, in urban areas, there has been proposed a type in which a water storage tank is incorporated in a water supply and distribution system so that new water is always stored in the water tank, and there are various structures. These water storage tanks have a water storage tank interposed in a normal water distribution pipe or a bypass pipe, and the water storage tank itself is regarded as a part of a water supply and distribution system. While the water is being supplied, the water in the water tank is constantly replaced, which is excellent in ensuring the quality of the water in the tank. However, if the water storage tank has a diameter several tens of times the size of the water distribution pipe, the flow rate in the water storage tank will be extremely reduced, or water will stagnate or change due to a sudden change in cross-sectional shape. Requires a considerable flow rate, and there are many problems in terms of adequacy as drinking water, economy, and maintenance. As a countermeasure for this, for example, a perforated pipe is inserted into the water tank (Japanese Patent Publication No. 58-39719).
No.), inserting a spiral partition plate (actual publication 59-
138592) and changing the jet flow of inflow water (Japanese Patent Publication No. 58-45547) have been proposed, but they cannot be said to have achieved a sufficient effect. SUMMARY OF THE INVENTION [0004] The present invention has been made in view of the above situation, and has as its object to prevent water from remaining in a water storage tank provided on a water distribution pipe. Emergency water storage with multiple divided water tanks that can reduce the amount of water required for replacement, supply quick and large quantities of clean water with good water quality in an emergency, and have good workability and excellent quality. A tank is provided. [0005] In order to achieve the above object, the present invention provides an emergency water storage tank device having a plurality of divided water storage tanks. It is composed of a water storage tank installed in the path, and is normally passed from the upstream pipe to the downstream pipe via the water storage tank, and the water stored in the water storage tank can be used as emergency water during a disaster such as an earthquake. In the water tank device, the inflow pipe is provided on one end plate and the other end plate is provided.
The outflow pipe is connected to the plate, and the inner diameter D of the water storage tank is changed to the inner diameter d of the inflow pipe.
And a cylindrical water tank with D / d = 5-10
In addition , a plurality of water storage tanks divided into a size that can be transported by land transportation are connected in series at a site by a connection pipe and installed on the path of the water distribution pipeline. In the emergency water storage tank device of the present invention, the water storage tank divided into a plurality can be stacked and arranged in accordance with the cross-sectional shape of the cut groove. Further, the emergency water storage tank device of the present invention has a cylindrical water storage tank, and an inflow pipe (intermediate water storage tank,
Alternatively, connect the connection pipe on the entry side for the final water tank, and connect the outflow pipe (connection pipe for the first water tank or the intermediate water tank) to the other end plate, and then flow in the inside diameter D of the water tank. With respect to the inner diameter d of the pipe (or connecting pipe), D / d can be set to 5 to 10. Here, in addition to the case where the distribution pipe is a main pipe from the beginning, there is an existing main pipe, a bypass pipe is provided in the main pipe, a water storage tank is provided in a path of the bypass pipe, and provided.
After installation of the bypass pipe, the bypass pipe may be used as the main pipe in some cases. [0006] Usually, when the flow of water in the water storage tank is observed, the water flows into the water storage tank installed in the path of the water distribution pipe, and when the water flows out of the water storage tank, especially when the amount of the inflowing water is small, the water flows into the water storage tank. The water stirring energy is small, and the water flow in the water storage tank tends to be formed at the shortest distance between the outflow and the inflow.
As a result, a considerable amount of water stays in the water tank,
Water quality will be degraded. The degree becomes more remarkable as the capacity of the water storage tank increases. The emergency water storage tank device of the present invention is provided with a water storage tank divided into a plurality of parts that can be transported by land transportation in order to prevent water from staying in the water storage tank and constantly secure fresh water. And to be able to supply clean water flexibly in an emergency. The term "portable size by land transportation" means that the water tank is a size that can be transported from a factory to an installation location by a truck or a trailer. The portable size is intended to improve work efficiency and maintain quality by performing work such as welding and corrosion prevention in a factory. In addition, the capacity of the water storage tank is reduced, and the water storage tanks are connected in series to prevent the water flow passing through the water storage tank from being reduced, and to prevent the generation of a stagnation area as much as possible.
The connection of the water storage tank acts as a baffle to prevent stagnation of passing water. In addition, it is possible to flexibly cope with the buried space of the water storage tank. In addition, when the water tank divided into a plurality is stacked and arranged according to the cross-sectional shape of the cut groove,
The size of the excavation trench can be reduced. In the emergency water storage tank device of the present invention, the water storage tank is made cylindrical, and an inflow pipe (or connection pipe) is connected to one end plate of the water storage tank, and an outflow pipe (or connection pipe) is connected to the other end plate. , The inner diameter D of the water storage tank with respect to the inner diameter d of the inflow pipe is D / d
= 5-10. The reason for setting D / d = 5 to 10 is to make the replacement of water good, reduce the amount of stagnant water, and prevent deterioration of water quality. If D / d is less than 5,
If the water tanks have the same volume, the length L of the water tank will be long, and if D / d is greater than 10, the flow velocity will be reduced and water will be easily stagnated. Here, in FIG. 4, the vertical axis represents the water exchange characteristic in the water storage tank, and the initial concentration is 1 on the vertical axis.
The color water concentration is set to 00%, the degree of substitution is plotted on the horizontal axis, and D / d is shown as a parameter. In FIG. 4, the colored water concentration is a degree (concentration) of replacement of water in the water tank, and the degree of replacement indicates a ratio of the amount of water required for water replacement to the volume of the water tank. In FIG. 4, a is D / d
≒ 1, b is D / d = 7, c is D / d = 10, c is D / d
= 15 and e are D / d = 20, indicating that the degree of replacement is good in the range of D / d = 5 to 10 in the present invention. The present invention, as described above, is intended to minimize the stagnation area of the water storage tank and secure the supply of clean water in an emergency in combination with the division of the water storage tank into plural parts and the D / d ratio. FIG. 1 is a perspective view of an emergency water storage tank device according to the present invention. The emergency water storage tank device is a water storage tank divided into a plurality of water storage tanks by land transportation. Water tank 2,
A first water storage tank 3 is provided. Each of the water storage tanks 1, 2, and 3 is a portable size by land transportation. The water flowing from the inflow pipe 4 flows into the water storage tank 2 from the water storage tank 1 via the connection pipe 6, and from the water storage tank 2 to the water storage tank 3 via the connection pipe 7.
And flows out of the water storage tank 3 to the outflow pipe 5. In FIG. 1, a gate valve 10 and a check valve 11 are provided between the upstream water distribution pipe 8 and the inflow pipe 4, and a gate valve 12 is provided between the downstream water distribution pipe 9 and the outflow pipe 5. In addition, a bypass pipe 13 is installed, and a gate valve 14 and a check valve 15 are provided in the path of the bypass pipe 13. Figure 1 shows the water tank 1,
FIG. 2 shows an example in which water tanks 1, 2, and 3 are stacked.
3 shows a state in which 3 is arranged in a plane. FIG.
Here is an example of stacking inside. FIG. 1 shows an embodiment of an emergency water tank apparatus to which the present invention is applied. In FIG. 1, each of the water storage tanks 1, 2, and 3 in the emergency water storage tank device of the present invention has a size inside diameter D2000 mm and a length L12 m that can be transported by land transportation. The inner diameter d of the inflow pipe 4 and the connection pipes 6 and 7 is 200 mm. Here, D / d is 10, and the degree of replacement of water for obtaining clean water having a color water concentration of substantially zero is 2.9 at a color water concentration of 99% and 3 at a color water concentration of 99.9%. 1, there is no stagnation over the entire area of each water storage tank, and no deterioration in water quality occurs. When an earthquake occurs, the gate valve 10 is shut off, and the water stored in the water storage tanks 1, 2, and 3 is pumped up by a pump (not shown) and used for drinking water, domestic water, fire prevention water, and the like. (1) According to the present invention, water can be prevented from staying in a water distribution pipe and a water storage tank installed on the way, and the amount of water required for replacement can be reduced. Can supply safer water. (2) Since the water storage tank is of a portable size, the task is to improve work efficiency such as welding and corrosion prevention and maintain quality. In addition, the capacity of the water storage tank is reduced, and the water storage tanks are connected in series, so that the water flow passing through the water storage tank is prevented from lowering, and the generation of a stagnation area can be prevented as much as possible. (3) Since the connecting portion of the water storage tank acts as a baffle plate, it prevents stagnation of passing water. (4) It is possible to flexibly respond to the buried space of the water storage tank, and when the water storage tank divided into a plurality is stacked and arranged according to the cross-sectional shape of the open groove, the size of the excavation groove can be reduced. it can.
