Therefore, there is a problem in the rainy season suddenly a large amount of rainwater discharged to the sewer or river, the backflow of the sewage or flooding of the river. In addition, during the dry season, because the soil could not absorb enough moisture, the rivers were easily depleted, and the surrounding vegetation and trees died.

In particular, during the dry season, water cannot be supplied from the river because water for various purposes such as apartment complexes or urban landscaping is prevented from being killed or road cleaning.

In order to solve these problems, the rainwater that is temporarily blown up is stored and gradually discharged to prevent backflow of the sewer system or flooding of the stream, and to prevent the exhaustion of the river by gradually discharging water stored in the dry season. A storage tank is being constructed as a facility for various purposes such as tree water for landscaping of an apartment, road cleaning or fire protection.

And at least one of a plurality of basic block portions simultaneously contacted in two rows by concave or convex portions formed around the other end to form a passage through which rainwater flows.

Hereinafter, specific embodiments of the present invention will be described with reference to the drawings.

One. Of the first embodiment Storage tank (Figure 5 To  10)

As shown in FIG. 5, the storage tank of the first embodiment includes one block, that is, a basic block 10 formed by closing both the upper and lower surfaces of the basic block part, the single finishing block part, and the composite finishing block part. ), It is formed of a single finishing block 20 and a composite finishing block 30 has an overall hexahedral shape. As shown in FIG. 7, a conduit (indicated by a dotted line) is formed in the blocks 10, 20, and 30 as a space in which rainwater may be stored.

As shown in FIG. 8, the basic block 10 has recesses or convex portions 12 formed around both side ends thereof, and is combined with other basic blocks having the same shape. And the inner edge portion is provided with a fixing portion 14 to fix the basic block 10 coupled adjacently. In detail, the adjacent basic blocks 10 may be strongly fastened using a steel wire inserted into a hole formed inside the inner edge of the basic block 10. In addition to this method, adjacent basic blocks may be fastened by bolts or nuts. The fastening structure of the fixing part 14 is a well-known technique, and since the method used in the conventional prefabricated storage tank described in the background art may be adopted, a detailed description thereof will be omitted.

The aggregate of the basic blocks 10 is composed of two or more rows, and by configuring the same number of basic blocks 10 constituting each row, the overall shape of the storage tank can be configured as a hexahedron. In FIG. 5, the single finishing block 20 formed as described above forms four rows and maintains contact with each other.

As shown in FIG. 9, the single finishing block 20 has one side closed and a concave or convex portion 22 formed around the other end, and a fixing portion for fastening with the basic block 10 ( 14). The single finishing block 20 formed as described above may form one end or the other end of the conduit, and may form the inlet 1 or the outlet 20 of the rainwater on the upper surface or the side of the single finishing block 20.

The composite finishing block 30, as shown in Figure 10, one side is closed and a concave or convex portion 32 is formed around the other end is combined with the two basic blocks 10 at the same time, the basic block Fixing part 34 for fastening with 10 is provided. The rainwater inside the composite finishing block 30 formed as described above is converted to 180 ° in the flow direction, that is, the flow direction.

It is known in the art that a watertight agent for watertightness can be added to the joint portion of the blocks 10, 20, 30 formed as described above so that the rainwater stored in the storage tank does not leak.

The storage process of rainwater, the discharge and the cleaning process of the sediment using the hexahedral-shaped storage tank configured as described above are as follows.

First, if rainwater is supplied through the inlet 1 of the single finishing block 20, it is stored while maintaining the same water level in the entire pipeline while flowing along the curved pipe.

Rainwater is discharged to the outside through the outlet (2) of the single closing block 20 located in the other end of the pipeline while the rainwater flows through the pipeline as in the supply process. Therefore, the rainwater flows along the pipeline during the supply or discharge of rainwater, thereby minimizing contamination due to the propagation of microorganisms in the rainwater by maintaining uniform time of stagnation in the rainwater storage tank.

On the other hand, such a storage tank, the longer the period of use is accompanied by the generation of deposits on the bottom of each block (10, 20, 30), it is necessary to remove it periodically. To this end, one or more washing water inlets may be provided at one end or a middle block of the conduit, and the washing water discharge part may be provided at a block located at the other end of the conduit.

The washing water inlet may be installed in the single finishing block 20 in which the rainwater outlet 2 is formed, but may be installed in another block located in the middle of the conduit in order to maintain a large flow rate of the supplied washing water.

At this time, the washing water discharge portion is preferably formed on the lower side of the block provided with the inlet of rainwater, that is, the basic finishing block 20 provided with the inlet 1 in FIG. This is because the sediment contained in the initial rainwater is mainly deposited on the bottom of the block close to the inlet 1, so that the washing water is advantageously discharged in a direction opposite to the flow direction when the rainwater is supplied.

In order to further improve the washing efficiency by the washing water, a slope may be formed on the bottom surface (not shown) supporting the prefabricated storage tank so that the block in which the washing water inlet is installed is located higher than the block in which the washing water outlet is installed.

Alternatively, to increase the flow rate of the wash water in the conduit, mortar or plain concrete on the bottom of the block constituting the conduit so that the inner bottom of the block with the wash water inlet is located higher than the inner bottom of the block with the wash water outlet. It can be poured to form a slope.

2. Of the second embodiment Storage tank (Figure 11 To  13)

11 to 13, the storage tank of the second embodiment is an example in which the storage tank of the dodecahedron is configured by modifying the overall shape according to the conditions in which the storage tank is installed by changing the storage tank and the assembly method of the first embodiment.

In this way, in order to form a storage tank having a polyhedron having six or more polyhedrons, the number of the basic blocks 10 constituting adjacent columns among the basic blocks 10 constituting two or more rows is different, but the composite finish is a part where the rainwater flows. By arranging the blocks 30, a storage tank of various polyhedrons can be configured.

Therefore, it can be seen that it is possible to configure various types of storage tanks such as hexahedron, octahedron, decahedron, and dodecahedron while using only the basic block 10, the single finishing block 20, and the composite finishing block 30.

By using this, there is an advantage in that the storage tank can be formed while making a spatial harmony with other underground structures installed in the basement of the downtown area.

3. Of the third embodiment Storage tank (See Figure 14)

That is, the basic block portion is composed of a lower block 10a having an open upper surface and an upper block 10b having an open lower surface, and forming a concave portion or a convex portion at each of the opened upper and lower ends, respectively, to be coupled to each other. As a result, the basic block 10 according to the first embodiment is formed. In the same way, the single finishing block portion is composed of a lower block 20a and an upper block 20b, and the composite finishing block portion is also composed of a lower block 30a and an upper block 30b.

At this time, as shown in Figure 14, the rainwater inlet 1 may be formed in the upper block 20b of the single closing block portion, the rainwater outlet 2 may be formed in the upper block 20b of the other single finishing block portion.

Although not shown, any one of the basic block portion, the single finishing block portion, and the composite finishing block portion may be used in combination with a single block (see FIGS. 8 to 10) constituting the storage tank of the first embodiment. Of course.

4. Of the fourth embodiment Storage tank (See Figure 15)

As shown in FIG. 15, the storage tank of the fourth embodiment further expands the storage capacity of the storage tank of the third embodiment, and includes the basic block 10, the single finishing block 20, and the composite finishing block 30 of the first embodiment. ) Consists of three blocks each.

That is, the storage tank of the fourth embodiment is between each of the lower blocks 10a, 20a, 30a and the upper blocks 10b, 20b, 30b constituting the basic block portion, the single finishing block portion, and the composite finishing block portion of the third embodiment. The intermediate blocks 10c, 20c, and 30c are inserted in the structure. At this time, the upper and lower portions of each of the intermediate blocks (10c, 20c, 30c) are formed with recesses or convex portions, respectively, at the same time to the lower blocks (10a, 20a, 30a) and the upper blocks (10b, 20b, 30b) of the corresponding position Combined.

In particular, the storage tank of the fourth embodiment has the advantage that it is easy to expand the storage capacity of the storage tank of the third embodiment. That is, when the storage tank is installed and used in the third embodiment and the storage capacity is insufficient to expand the storage tank, there is no need to replace the entire storage tank. In FIG. 14, the lower blocks 10a, 10b, and 10c are left as they are. After separating only 20b, 30b, insert the middle block (10c, 20c, 30c) in Figure 15 and again the upper block (10b, 20b, 30b) to the middle block (10c, 20c, 30c) at the top By combining, as in the fourth embodiment, a storage tank having an extended storage capacity can be configured.

Although not shown, any one of the basic block portion, the single finishing block portion, and the composite finishing block portion of the fourth embodiment may use a single block (see FIGS. 8 to 10) constituting the storage tank of the first embodiment. Of course, the lower block and the upper block constituting the storage tank of the third embodiment can be used in combination.
