Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a water storage device that utilizes a river.

Conventionally, in order to utilize flowing water from rivers, dams have been constructed at a large amount of cost and using large areas of land.

The present invention provides a water storage device for river use, which makes it possible to use river water at a relatively small cost and without requiring special land.

Embodiments of the present invention will be described below with reference to the drawings.

In one embodiment of the present invention shown in FIGS. 1 to 4, 10 is a box-shaped water tank installed by excavating the bottom of a river, and a plurality of conocrete blocks 12 made of reinforced concrete are connected by means not shown. It is configured as follows. A large number of water tanks are installed at the bottom of a river, for example, every 500 m in length. This water storage tank 10 has an upstream end face 13 and a downstream end face 15 closed, and side faces 16 on both sides. The bottom surface 18 is closed. 19 is a column provided on the concrete block 12. A large number of holes 21 are bored in the upper surface 20.
For example, about three filter members 22 made of fine nylon cloth are stacked on top of the upper surface 20 of each concrete block 12 to filter running water 90, and a large number of gravel 23 are stacked on top of each concrete block 12. is arranged to protect the filter member 22 from solid matter etc. carried by the running water 90 and to filter the running water. Reference numeral 25 is a door that can be opened and closed like a water gate, and is normally closed, but for cleaning, it can be opened by a means (not shown) to allow access to the inside. 2G is a staircase.

Reference numeral 27 is an enclosure part that is integrated with one conocrete block 12 and surrounds the outside of the door 25 and stairs 26. 3
0 is a pipe serving as a pumping means for pumping up water in the water storage tank 10.

In the configuration as described above, the flowing water of the river 90
When water flows over the water tank 10, gravel 23 and filter member 22
The water is filtered through the filtration means and passes through the hole 2J into the water storage tank 10.
Water flows into the interior and is stored.

This stored water can be pumped up from the nozzle 30 by a pump (not shown) and used for various purposes. For example, it can be used as industrial water, agricultural water, or for water supply by constructing a water purification plant near a place of demand such as a city.

The water storage tank 10 is constructed by sequentially connecting concrete blocks with a rectangular cross section in a row in the direction of the flowing water 90, instead of connecting a plurality of concrete blocks 12 in the horizontal direction as in the previous embodiment. Good too. Also, water tank 10
The concrete blocks 12 may also be connected in the vertical direction, or a plurality of water tanks 10 may be stacked in the vertical direction.

In another embodiment of the present invention shown in FIGS. 5 to 7, a concrete layer 50 having a substantially horizontal upper surface is formed by pouring concrete in a part of a garden excavated at the bottom of a river. A water tank 10 is arranged. Concrete blocks 51 constituting the water storage tank 10. are connected laterally and in the direction of the flowing water 90 by means not shown, and both ends are closed at about 500 m, for example. Most of these concrete blocks, for example, have a square section with a circumference of about 2.2 m on a side and a length of about 3 m, and holes 52 with a diameter of about 5 Q cm through which clean water passes are provided at the top of both sides. At the bottom of both sides, square holes 53 each measuring about 60 cm on a side are formed to allow water that may contain sediment such as sludge to pass through. These holes 52 and 53 are arranged in a 13-in-like manner with the adjacent ones to allow water to pass therethrough, and are closed at both ends of the water tank 10, except as described below. . Moreover, each concrete block 51 has a diameter of 10 mm on two sides, for example.
A large number of holes 54, each about cm in diameter, are opened so that water can flow in from above. Reference numeral 55 denotes a pumping chamber connected to one side of the water tank 10, the surroundings of which are made of reinforced concrete, the bottom of which is lower than that of the tank 10, and the second part of which is higher. 51 has the holes 52 and 53 formed on the side surface of the joint part, through which the inside of the drawing chamber 55 and the inside of the water storage tank 10 are constantly communicated, and the hole 53 can be opened by the door 57 when necessary. ru”: The sea urchin is turning. 58 is a pipe whose lower end is placed slightly upward in order to draw water from the pumping chamber, and 60 is a pipe Ii when the lower end is placed in the lower part of the pumping chamber 55.
J: J4i 57 is opened to allow water that has read the sludge in the lower part of the water storage tank 10 to flow through the holes 53 from each concrete block 51 into the scooping chamber 55.

23 is gravel mainly made from cobblestones found in rivers, and is placed directly above the water tank 10, with a hole 5 into the water tank.
4 constitutes a filtration means for filtering water flowing in.

Similar to the water storage tank 1O, which is placed above the water storage tank 10 with gravel 23 interposed therebetween, a large number of concrete blocks 63 made of reinforced concrete IJ are connected to form a box shape, and relatively clean water passes therethrough. A waterway with many holes 6 on both the top and bottom sides.
4 is the opening. The top and sides of this waterway are filled with gravel 23.

This channel allows water to flow continuously from the upstream side, and ends above the most upstream water tank 10, and the end face on the upstream side may be closed or have many holes as necessary. It is designed to allow filtered water to flow in. Streaming water 90 flows on the gravel 23 above the waterway 62. This running water is filtered through the gravel 23 and enters the water channel 62, further filtered through the gravel 23, and then enters the needle tank IO. Therefore, fairly clean water flows into the water tank 10 and is held there, and if necessary, all the river water flows downstream through the waterway 62, and the upper part is used for children's play areas, etc. It is possible.

FIG. 8 shows that in the embodiments shown in FIGS. JL 2
A waterway 62 similarly constructed by connecting inclined concrete blocks is shown arranged with gravel 23 interposed therebetween.

AiJ mentioned. In this invention, the bottom of the river is excavated and the water storage tank 10 is constructed and used, so running water 90 can be easily filtered and stored at low cost and without using special land. This has the effect that it can be used for various purposes.
