1, the non-point pollution source reduction type building block 100 according to the present invention includes a bottom plate 110, a ceiling plate 120, and a filtration column 130 filled with a filter medium 140 And one or more bottom plates 110, a top plate 120 and a filtration column 120 are assembled to form a storage space according to the size of the storage tank.

Also, the storage block 100 is constructed as a structure having one or more layers by stacking the filtration columns 120 and the ceiling plate 130 in one or more stages.

The bottom plate 110, the top plate 120, and the filtration column 130 are made of polypropylene, and can be constructed with a small number of man-made structures by weight reduction. No noise and dust are generated in the construction, It is possible to construct and to prevent leakage of water. Of course, the bottom plate 110, the top plate 120, and the filtration column 130 may be made of concrete, steel, or the like.

As shown in FIG. 2, the bottom plate 110 and the top plate 120 are composed of a plate-shaped main body and column assembly holes 111 and 121 formed at the center of the main body.

The pillar assemblies 111 and 121 may have a ring-shaped support tab for supporting the filtration column 130 at the bottom so as to prevent the filtration column 130 from falling down. In addition, One or more keys 113 and 123 may be applied.

In addition, the main body of the bottom plate 110 and the top plate 120 are provided with one or more holes 112, 122 penetrating up and down.

The holes 112 and 122 are applied for filtration of stored rainwater or the like.

The holes 112 and 122 function to infiltrate the rainwater into the ground, and when the rainwater consists of two or more storages, it functions to guide the rainwater into the storage space of the bottom layer.

The bottom plate 110 and the ceiling plate 120 are applied with the filtering nets 114 and 124 so as to prevent the loss of the filtering material 140 and to filter contaminants.

As shown in FIG. 3, the bottom plate 110 can be configured by connecting a filter net 114 between two upper and lower plates 110-1 and 110-2 (which may use one kind of product having the same structure) There is an advantage in that foreign matter of various sizes is filtered through the selection of the filter 114. As another example, it is also possible that the bottom plate 110 is insert-injected with the filter net 114. That is, the filtering net 114 is entirely installed in the bottom plate 110 so that the bottom plate 110 functions as a filter to perform the primary filtration by the filtration column 130 and the secondary filtration by the bottom plate 110 .

In the drawing, the filter net 114 is shown to have a portion corresponding to the center, that is, the filtration column 130, but it is also configured to block a portion corresponding to the column assembly hole 111, so that the filter medium falls from the filtration column 130, .

The ceiling plate 120 has the same structure as the bottom plate 110. Therefore, since both the top plate 120, the bottom plate 110, and the filtration column 130 have a filtration function, the filtration efficiency by the multistage filtration is enhanced.

The pillar assemblies 121 of the ceiling plate 120 are sized such that the filtration pillar 130 is coupled to the lower and upper pillar assemblies 121, respectively.

Therefore, it is also possible that the bottom plate 110 and the ceiling plate 120 are not made of different structures but a single product.

The filtration column 130 has a plurality of filtration holes 131, which are hollow tubes having a filter medium filling part vertically passing therethrough and communicate with the inside and the outside.

The bottom of the filtration column 130 is inserted into the bottom plate 110 and the top of the filtration column 130 is inserted into the column assembly holes 111 and 121 of the ceiling plate 120. Key grooves 132 and 133, .

The filtration hole 131 functions to allow the rainwater to flow into the filtration column 130 according to the method of the storage tank and to discharge the purified water filtered through the filtration material 140 out of the filtration column 130.

In the case of the discharge type storage tank, the filtration hole toward the inlet port allows the rainwater to flow, while the filtration hole to the discharge port discharges the purified water from which the contaminants have been purified through the filter medium 140.

In the case of the permeable storage tank, the rainwater flowing through the upper portion of the filtration column 130 is filtered through the filter medium 140 and then discharged through the filtration hole 130.

The filtration column 130 may be provided with an assembly protrusion 134 or 135 at the bottom and the top.

The assembly projections 134 and 135 are preferably formed to have a smaller outer diameter than the filtration column 130 in the filtration column 130 so as to form a jaw. The assembly projections 134 and 135 are formed in the column assembly holes 111 and 121 of the bottom plate 110 and the top plate 120 Respectively.

Such assembling projections 134 and 135 are also applicable to interlocking of the pillars 130, as shown in FIG. That is, it is also possible to stack two or more filtration columns 130 vertically according to the height of the storage tank. At this time, the connection socket 150 is used between the assembly projections 134 and 135 of the vertically stacked columns 130 . The connection socket 150 has an effect of increasing the connection strength of the filtration posts 130 by surrounding the adjacent assembly projections 134 and 135.

The filter material 140 in the filter column 130 is filled with the filter material 140 (which is not limited to a specific value since various particle sizes can be used as the activated carbon and the zeolite).

The protection column 141 is applied to prevent the filter material 140 from leaking through the filtration hole 131. [ For example, as shown in FIG. 4, the protection net 141 is a tubular structure in which the upper and lower portions penetrate and are closely contacted with the inner wall of the filtration column 130. Alternatively, the protection net 141 may have a net shape in which the filter medium 140 is contained therein. It is also possible that the protection net 141 is inserted into the filtration column 130.

The non-point pollution source reduction type building storage block 100 according to the present invention is assembled with a wall-type finishing wall at a periphery thereof to create a storage space therein. The car finishing wall may be made of polypropylene, concrete (field cast, precast concrete), or steel.

As another application example, it is possible to install an auxiliary reservoir structure (BOX) such as concrete, steel, etc., and to install a prefabricated reservoir block (100) with a nonpoint pollution source in the reservoir structure, so that contaminants can be discharged to be filtered.

Meanwhile, since the filtration column 130 has a filtration hole 131, the filtration column 130 may have a weak structural strength. In order to supplement the filtration column 130, the support column 136 is installed inside the filtration column 130.

The support base 136 may have both a shape and a space in which there is no space (the interior of which may be filled with a filter medium, and holes may be provided on the upper and lower portions and the peripheral portion) And the upper and lower portions can be supported on the bottom plate 110 and the ceiling plate 120 or can be supported on the filtration column 10 through the radial spokes 137 as well. For example, upper and lower longitudinal grooves are formed on the inner circumferential surface of the filtration column 130, and the spokes 137 of the supporter 136 are slidably fitted in the grooves.

The support member 136 may be integrally formed with the filtration column 130.

The rainwater storage tank using the prefabricated storage block of the nonpoint source reduction type according to the present invention can be constructed as a discharge type for a river or a sewage treatment system, an underground penetration type, and the like.

2. Construction of foundation layer.

The floor of the underground space is leveled and the foundation foundation layer 10 is constructed.

The underlying foundation layer 10 comprises a gravel layer 11, a sand layer 12, and a water layer 13.

The sand layer (12) is made of sand on the gravel layer (11) and enhances the order effect.

The aeration layer 13 is formed by laying a water receiving sheet on the sand layer 12, and it is possible to use a combination of a water receiving sheet and a protective sheet (earth fiber or the like) as well as the water receiving sheet alone.

At this time, a water receiving sheet or the like is also installed on the peripheral portion (inner wall) of the underground space.

3. Construction of prefabricated reservoir block with reduced nonpoint pollution source.

As shown in FIG. 7, bottom plates 110 are installed on the order foundation layer 10.

The assembling protrusion 134 of the bottom of the filtration column 130 is inserted into the column assembly hole 111 of the bottom plate 110 and the filtration column 130 is mounted on the bottom plate 110.

And the filter material 140 is filled in the filter material filling part inside the filtration column 130.

The ceiling plate 120 is installed by fitting the column assembling hole 121 of the ceiling plate 120 into the upper assembling protrusion 135 of the filtering column 130 after the filling of the filter media 140 is completed.

The filter column 130 is installed on the ceiling plate 120 in the same manner as described above and the filter material 140 is filled in the filter material filling portion of the filter column 130. Then, (120) is installed to construct the two-stage non-point pollution source reduction type prefabricated storage block (100). In the same way, three or more reservoir blocks are constructed.

In this process, the inlet (1) and outlet (2) communicating with the storage space of the non-point pollution source reduction type prefab storage block (100) are installed. The inlet (1) is arranged at the upper part of the storage space and the outlet (2) is arranged at the bottom.

4. Packing.

The upper portion of the non-point pollution source-reduced prefabricated storage block 100 is packed to construct the order or permeable packing layer 20.

For example, in the orderly packing layer, a water-receiving sheet 21 is laid on an upper portion of a non-point pollution source-reduced prefabricated storage block 100, and a road surface layer 22 is formed by laying a packing material (gravel, paving stone, elastic packaging material, etc.). The permeable packing layer is formed by installing permeable packing material capable of permeating rainwater such as a permeable block. In addition, the permeable packing layer 40 may be used together with a filter material such as zeolite to primarily filter the contaminants in the permeation process of the rainwater and maximize the filtration capacity.

It is also possible to complete the construction of the stormwater stormwater stor- age tank through the above-described process, and to additionally arrange the sediment stor- age on the upstream side of the inlet 1 to store rainwater after sedimenting the sand or the like.

In addition, it is also possible to construct two or more discharge-type rainwater storage tanks and connect them in a cascade so that rainwater filtration in two or more stages can be performed.

In the non-point source reduction type prefabricated storage block 100, a circulation fan for circulating rainwater in the storage space may be applied. The circulating fan rotates through a driving force of a motor or the like installed in a machine room on the ground or in the ground to circulate the rainwater.

In this process, the rainwater flows into the filtration column 130 through the filtration hole 131 of the filtration column 130, and the contaminants are filtered while passing through the filtration media 140. The purified water filtered by the pollutant through the filter medium 140 is discharged through the discharge port 2.

<Penetration stormwater storage>
