Description

{INFILTRATION TRENCH WITH FUNCTION OF MONITORING}

Embodiments of the present invention relate to infiltration ditches, and more particularly, to infiltration ditches capable of removing high concentrations of contaminants and having a monitoring function.

As is well known, pollution sources generated in urban areas are classified into point pollution sources and nonpoint pollution sources. Among them, the point pollution source refers to a pollutant source having a specific discharge route such as domestic sewage and factory waste water, which can be expressed as a single point, and nonpoint pollution sources are classified into unspecified places such as cities, roads, farmland, It refers to the source of emission of a water pollutant.

The non-point pollution sources are scattered unlike the point pollution sources that are continuously generated at specific points such as domestic sewage or factory wastewater, and it is difficult to grasp the accurate outflow route of the pollution source and the inflow is characterized as non-persistent. Especially, it is difficult to collect pollutant outflow and discharge route clearly, and it is difficult to collect pollutant, and the amount of emission and the amount of emission depend greatly on weather conditions such as precipitation and the pollutant is diluted and diffused and is discharged to a large area.

Conventionally, since the outflow of nonpoint source is concentrated only at the time of rainfall and dispersed in a wide area, the importance of the source as a source is not recognized. However, the first-flush effluent has a high effluent concentration of the non-point-blanking material, and in the case of urban areas, the possibility of containing toxic substances such as heavy metals is high and appropriate control method is required.

In particular, pollutants such as soil, nutrients, and heavy metals that leach out along with rainfall in nonpoint sources are difficult to collect, and if they enter the river directly, they can contaminate water quality.

Currently known as a facility to reduce the non-point pollution source, there are reservoir type, permeation type, vegetation type, device type, sewage treatment type, etc. However, since it is to remove a specific pollution source contained in the polluted water, It is necessary to develop an infiltration ditch that can lead rainwater that has no nonpoint source to groundwater.

The height of the second inflow pipe 120 may be the same as the height of the grating 210 and the first filtration layer 311. This structure allows the rainwater flowing through the second inflow pipe 120 to gradually pass through the contaminant removal tank 200 and to flow to the infiltration trench 300 while primarily removing the high-concentration contaminants.

The residual water discharge pipe 130 is a pipe for discharging residual water in the sedimentation tank 100 and is preferably disposed upward from the bottom of the sedimentation tank 100 in the same direction as the first inflow pipe 110 It is good.

The residual water discharging pipe 130 may be formed with a predetermined size so that residual water discharged from the settling tank 100 can be quickly discharged to the outside. As a specific example, the particle size of the gravel constituting the residual water distribution layer 140 is preferably the same as the particle size of the gravel constituting the second filtration layer 313, but is not limited thereto.

The bypass pipe 150 may be installed in a direction crossing the first inflow pipe 110 on the same height as the first inflow pipe 110.

Meanwhile, an angle adjusting screen 160 may be further provided in front of the second inflow pipe 120 so as to be inclined to face the two inflow pipes 120.

Specifically, the lower end of the angle adjusting screen 160 may be fixed to the lower portion of the second inlet pipe 120, and the upper end of the angle adjusting screen 160 may be connected to the second inlet pipe 120 So that the inclination angle a can be adjusted.

Each of the screen units 161 includes a mesh member 161a formed therein as shown in FIG. 5, And a rectangular frame 161b coupled to the rim of the mesh member 161a. However, the present invention is not limited to the configuration in which the pair of screen units 161 are connected to the right and left, and the present invention may include a plurality of screen units 161 connected in different numbers.

The pair of screen units 161 may be fixed to one connection frame 163 using a plurality of fixing members 165 as shown in FIG.

More specifically, the fixing member 165 and the connection frame 163 have bolts 167 (for example, a bolt screw or the like) passing therethrough and nuts 168 (for example, Butterfly nuts, etc.).

The contaminant removing tank 200 will be described in detail with reference to FIGS. 2 to 4. FIG.

FIG. 2 is a conceptual view showing a contaminant removal tank in an infiltration trench according to an embodiment of the present invention.

2, the contaminant removal apparatus 200 includes a sand bottom layer 260 (see FIG. 1) formed at a predetermined height on the upper side of the ground layer 270 (see FIG. 1) A contaminant removal device 220 coupled to the upper portion of the gap forming member 240 to form a plurality of layers, and a grating 210 covering the upper portion of the contaminant removal device 220.

The grating 210 may be formed in the same height as the lower end of the second inflow pipe 120 and horizontally disposed.

The gap forming member 240 is installed between the lower end of the pollutant removing device 220 and the bottom of the gap forming member 240 and forms a hollow space having a predetermined height from the bottom to the lower portion of the pollutant removing device 220. As a result, the rainwater that has passed through the pollutant removal device 220 is collected into the empty space of the predetermined height made by the gap-forming member 240, and is formed at the lower portion of the gap- Can be drained to the second filtration layer 313 (see FIG. 1) which is in contact with the sand bottom layer 260 (see FIG. 1). That is, since the pores of the second filtration layer 313 (see FIG. 1) made of gravel are relatively large as compared with the sand bottom layer 260 (see FIG. 1), drainage can occur.

The pollutant removing device 220 may be coupled to the upper end of the gap forming member 240, and may have a structure in which a plurality of pre-, post-, left-, right-, and upper- In addition, the contaminant removal device 220 may be provided with an accommodation space 221 in which a filter material 230 made of zeolite or fiber can be filled.

Specifically, the contaminant removing device 220 may have a structure in which at least two layers are stacked on the upper end of the gap-forming member 240.

Preferably, the pollutant removing device 220 connected to the front side among the plurality of the pollutant removing devices 220 (that is, the four pollutant removing devices located on the left side of FIG. 2) is assembled in a state filled with the filter media 230, It is preferable that the removal device 220 is assembled in a state in which the filter medium 230 is not filled in the accommodation space 221.

Considering that the flow direction of the rainwater discharged through the second inflow pipe 120 is from the front to the rear (that is, from left to right in FIG. 2), the contaminant removal device 220 disposed at the front is provided with the filter material 230 The pollutant removing device 220 disposed in the rear part serves to remove contaminants remaining in the backward order and is divided into several stages, So that the effect of removing high-concentration contaminants can be ensured.

FIG. 3 is a perspective view illustrating a contaminant removal apparatus used in a contaminant removal tank according to an embodiment of the present invention, and FIG. 4 is a plan view illustrating a contaminant removal apparatus shown in FIG. Referring to FIGS. 3 and 4, the decontamination apparatus 220 includes a box housing 222 having an upper opening and a receiving space inside.

The box housing 222 includes a pair of connection protrusions 223a protruding outward from two adjacent upper rims and a connection protrusion 223b provided on the remaining two upper rims adjacent to each other, (223b). Accordingly, the plurality of box housings 222 are connected to the front, back, left, and right sides on the same height, so that they can be used for a wide area.

In addition, a plurality of longitudinal ribs 225 may be formed on the inner surface of the box housing 222 with a gap therebetween. The longitudinal ribs 225 may have a shape in which the projecting width gradually increases toward the bottom.

Accordingly, even when the box housing 222 is made of a lightweight plastic material and the contaminants of high and high concentrations are accommodated together, the box housing 222 may not be damaged or damaged. Further, even when the box material is filled in the box housing 222, it is possible to secure the structural strength required for installation and use.

The box housing 222 may be provided with cylindrical grooves 224 at lower corners of the box housing 222. Specifically, four cylindrical grooves 224 may be provided one by one through respective lower corners of the box housing 222 And the upper end of the gap forming member 240 can be coupled through the cylindrical groove 224. [ Here, since it is a cylindrical groove 224, it is advantageous that directionality of the coupling direction is not required separately at the time of coupling with the gap-forming member 240, so that fastening can be performed quickly.

Meanwhile, a plurality of drain holes 227 are formed on the bottom surface of the box housing 222.

If the filter material 230 (see FIG. 2) is filled through the accommodation space 221, the rainwater that has passed through the filter material 230 (see FIG. 2) and the polluted matter is discharged downward through the drain hole 227 .

In contrast, if the receiving space 221 is used in an empty state, the contaminants may be filtered by the size of the drain hole 227, and only the contaminants may be discharged downward. Accordingly, the present invention is not limited to the number, shape, and arrangement of the plurality of drain holes 227, and various modifications may be made.

The bottom surface of the box housing 220 may further include a plurality of bottom protrusions 226 (see FIG. 4) formed for structural reinforcement together with the longitudinal ribs 225 described above.

The plurality of bottom protrusions 226 (see FIG. 4) may extend in a direction orthogonal to the lower ends of the plurality of longitudinal ribs 225, and protrude upward from the bottom surface of the box housing 222, Strengthen structural strength.

For example, as shown in FIG. 4, three bottom protrusions 226 (see FIG. 4) are formed in the vertical direction, and three lateral protrusions 226 .

This is because the bottom protrusion 226 is densely formed in the bottom surface of the box housing 220 in consideration of the fact that the weight load can be concentrated in the center portion of the box housing 220 where the grid pattern is formed.

The contaminant removing tank 200 (see FIG. 2) configured as described above includes contaminants of a high concentration at the initial stage, and is supplied to the contaminant removing device 220 through the filter media 230 and the contaminant removing device 220 After removing the high concentration of contaminants, the subsequent inflow may be introduced into the filtration layer of the infiltration ditch. 2) is formed at the same height as the lower end of the second inflow pipe 120 into which the rainwater flows from the settling tank 100 (see FIG. 1), and the first filtration layer 311), the inflowing rainwater after the high-concentration contaminants contained in the initial rainwater are removed from the contaminant removal tank 200 (see FIG. 2) can be introduced into the infiltration trench composed of a plurality of filtration layers will be.

Accordingly, it is possible to prevent the problem that the filtration layer is blocked due to the high concentration of contaminants contained in the initial rainwater, and that the rainwater is directly introduced into the filtration layer of the infiltration ditch, and the cost of replacement of the filtration layer can be reduced. In addition, management points can be minimized, and facility management can be advantageous.

Meanwhile, the infiltration ditch according to a preferred embodiment of the present invention may include a purified water collection unit 330 for collecting purified water purified through the infiltration ditch 300.

The perforated pipe 333 is installed to communicate with the lower end of the vertical pipe 331 and may be formed to be long from the bottom of the third filtration layer 315 (see FIG. 1) to collect purified water.

A downward slanting pipe 331b may be formed to extend from the vertical straightening pipe 331 and be inclined downward to the upper portion of the first filtering layer 311 And a horizontal extension pipe 331c extending from the horizontal extension pipe 331b.

For example, the horizontal extension pipe 331c is provided with a male thread, and the collecting container 335 for collecting the purified water may have a structure in which the inlet side is detachably coupled to the horizontal extension pipe 331c. For example, 335 may be provided with female threads to couple or separate the collection container 335 by fastening them to each other.

For this, the length of the first filtering layer 311 is preferably longer than the depth of the first filtering layer 311.

Specifically, the upper surface portion 345 provided on the inner side of the cover 343 may be formed of a mesh having perforations formed therein.

In addition, the side portions 344 of the receiving body 342 may have different shapes.

For example, the lower end 344a of the side portion 344 may be formed as a plate without a pore, and the upper end 344b of the side portion 344 may be formed of a mesh having a perforation.

According to this structure, when the first filtration layer 311 (see FIG. 1) is closed due to the inflow of impurities or insufficient maintenance, the poorness that does not pass through the closed first filtration layer 311 (see FIG. 1) The water can be forcedly drained toward the second filtration layer 313 (see FIG. 1) through the receiving body 342 and the forced drain pipe 347.

The lower end 344a of the side portion 344 may be formed by a plate having no pore. The reason why the lower end 344a of the side portion 344 is formed by the plate is that after the pore flows into the upper end of the receiving body 342, 347 to smooth out the storm.

That is, in contrast to the case where the front surface of the side portion 344 is formed of a mesh, the forced drainage effect can be improved according to the embodiment shown in FIG.

The lower end of the observation pipe 351 may be further provided with a lower cover 351a which can be opened and closed and the lower cover 351a may be formed on the same height as the lower portion of the third filtration layer 315 .

The support member 356 may be fixed to the upper end of the observation pipe 351 in a shape.

The indicating member 352 may be provided with a pivot shaft 352b connected to the supporting member 356 and a fixing protrusion 352a fixed to one end of the cable 353 on the opposite side of the pivot shaft .

According to such a structure, the pointing member 352 can be configured to be rotatable within a predetermined range at the upper portion of the infiltration ditch 300 (see FIG. 1) in accordance with the movement of the cable 353.

Preferably, an arrow-shaped directional guidance display may be provided on the tip end portion of the pointing member 352, and the shape thereof may be variously changed.

The cable 353 may be wound around a pulley 357 rotatably coupled to the cantilever portion of the support member 356. The other end of the cable 353 may be retained in the inside of the observation tube 351 And a boom 354 which is raised or lowered according to the change of the water level can be formed.

When the residual water is present on any depth of the first, second and third filtration layers 311, 313 and 315, the remaining water is filled into the inside of the observation pipe 351, , It can be lowered.

Thus, only the displacement of the indicating member 356 can be confirmed outside the infiltration ditch 300 (see FIG. 1) to determine the change in the level of the residual water.

It is necessary to design the infiltration ditch (300, see FIG. 1) so that no residual water remains in the filtration layer within the set period when there is no inflow into the facility after the rain is over, otherwise maintenance is required.

The level of the residual water can be easily and accurately grasped through the rotational displacement of the pointing member 352 of the monitoring unit 350, which can contribute to the maintenance aspect.

10, unlike the embodiment shown in FIG. 9, the monitoring unit 450 shown in FIG. 9 includes an observation pipe 451, a gear type water level meter (not shown) for detecting the residual water level inside the observation pipe 451 453). In this case, there is an advantage that a relatively accurate residual amount can be grasped by applying the gear system to the water level discrimination of the residual water.

As described above, according to the structure and function of the present invention, it is possible to remove the high-concentration contaminants and to have a monitoring function to check presence or absence of residual water in the facility.

In addition, it is possible to form a high-concentration contaminant removal tank between the settling tank and the infiltration trench, thereby removing the high-concentration contaminants contained in the inflowing inflow before reaching the infiltration trench. As a result, And the maintenance work can be facilitated.

Also, when there is a large amount of impurities or insufficient maintenance, the upper water aggregate filtration layer of the infiltration trench is closed, and when the infiltration into the infiltration trench is difficult, forced drainage can be performed toward the lower coarse aggregate filtration layer.

In addition, it is possible to analyze the periodic water quality of the infiltration trench, so that the condition of the facility and deterioration of the surrounding water quality can be accurately grasped.

In addition, the level of the residual water contained in the filtration layer of the infiltration ditch can be determined to check the facility status of the infiltration ditch quickly.

While the present invention has been described with respect to specific embodiments of the infiltration ditch having the monitoring function, it is apparent that various modifications can be made without departing from the scope of the present invention.

It is to be understood that both the foregoing general description and the following detailed description are exemplary, and are not to be construed in a limiting sense, and the scope of the present invention is indicated by the appended claims rather than by the foregoing description, All changes and modifications that come within the spirit and scope of the appended claims are intended to be embraced therein.
