Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, referring to FIGS. 1 and 2, a wall structure (hereinafter referred to as a 'wall structure') having a discharge water filtration function according to an embodiment of the present invention includes a wall 100, a purification layer 200, It comprises a filter cartridge (400a).

The wall 100 is configured to support the cut slope 310 and the fill slope 300 on the rear surface to secure the use space on the front surface. The wall 100 may be formed of a retaining wall or a wall forming a stone shaft.

On the other hand, the above-described wall 100, a plurality of drain holes 110 for discharging the discharged water on the front side is formed to prevent collapse (overturn) due to the discharged water. Here, the discharge water is meant to include both the inflow water flowing from the rear surface of the wall 100 and the filtered water filtered through the filter cartridge 400a.

Looking at the drain hole 110, the wall 100 is configured to include a drain tube 120 that is embedded in the wall 100 in a cylindrical tube shape so that the drain hole 110 is formed.

The purification layer 200 is filled to be adjacent to the rear surface of the wall 100 in which the drain holes 110 are located, and serves to purify the effluent discharged to the drain holes 110.

The purification layer 200 includes an active adsorption layer 210 and a filter layer 220, respectively.

Here, the active adsorption layer 210 is made of materials that adsorb and purify contaminants in the effluent, and known activated carbon may be applied.

The filter layer 220 is composed of aggregates and is configured to filter contaminants in the discharged water while the discharged water flows between the pores between the aggregates.

Meanwhile, the filter layer 220 may be configured to arrange aggregates having different sizes according to the size of the object to be filtered, thereby reducing the flow resistance of the effluent and increasing the filtration effect.

Thus, the filter layer 220, as shown, is divided according to the size of the filtering object, the first filter layer 221 made of coarse aggregate having a particle size larger than the set value, and the fine aggregate having a particle size smaller than the set value. It may be configured to include a second filter layer (222). Here, the aggregates of the first filter layer 221 and the second filter layer 222 may be made of various filtration materials including known filtration aggregates, and various other layer structures other than the two-layer structure may be used. Of course it can be achieved.

As described above, when the purification layer 200 has a structure including an active adsorption layer 210, a second filter layer 222, and a second filter layer 222, the purification layer 200 has a particle size. Correspondingly, the active adsorption layer 210, the second filter layer 222, and the first filter layer 221 are sequentially stacked vertically along the horizontal direction from the rear surface of the wall 100 to improve the filtration effect. It is preferably configured.

Hereinafter, the filter cartridge 400a for filtering the effluent filtered through the purification layer 200 will be described.

First, referring to FIG. 3, the wall 100 is formed in a cylindrical tube shape so that a drain hole 110 is formed inside, and is configured to include a drain tube 120 that is buried in the wall 100.

Thus, the filter cartridge 400a is configured to be detachably inserted into the drain pipe 120 in a cylindrical shape, and to filter the effluent discharged through the drain pipe 120.

In detail, the filter cartridge 400a includes a cartridge body detachably inserted into the drain pipe 120 and a filter unit 420 inserted into the cartridge body 410.

The cartridge body 410 is a cylindrical tube shape in which an internal flow path 411 is formed to allow the discharge water to flow therein. When inserted into the drain pipe 120, the outer circumferential surface is configured to face the inner circumferential surface of the drain pipe 120. It is configured to be detachably inserted into the drain pipe 120 by.

The filter unit 420 is inserted into the internal flow path 411 of the cartridge body 410 and is made of filtration material and serves to filter the discharge water flowing through the internal flow path 411.

On the other hand, the cartridge body 410, is formed to be exposed to the front of the wall 100 includes a detachable portion 412 to allow the user to easily detach the filter cartridge 400a from the drain hole 110 It is composed.

The detachable part 412 includes a gripping part that can be operated by a user, and is configured to protrude from the wall surface of the wall 100 as shown in FIG. 3 or to be located inside from the wall surface as shown in FIG. 4. Can be.

Here, the gripping portion is configured so that both ends are coupled to the ends of the cartridge body 410, respectively, as shown, so that the operator can grip the handle. However, this can be applied to various configurations as long as it can be gripped by an operator, such as being able to be coupled to the end of the cartridge body 410 in one embodiment. Since it corresponds to the configuration of the handle of, it will be omitted.

Hereinafter, the detachable structure of the drain pipe 120 and the filter cartridge 400a will be described.

Referring to FIG. 5, the filter cartridge 400b is detachably coupled to the drain pipe 140 in a screwed manner to improve the fastening force of the filter cartridge 400b.

To this end, a first screw thread 121 is formed on the inner surface of the drain pipe 120, and a second screw thread 413 meshes with the first screw thread 121 on the outer surface of the cartridge body.

On the other hand, when the filter cartridge 400b is coupled to the drain pipe 120 in a screwed manner, the filter cartridge 400b flows through the filter unit 420 due to securing the fastening force of the cartridge body 410. Resistance may increase. In this case, since the wall 100 may be cracked by the hydraulic pressure of the discharge water, it is preferable to adjust the configuration of the filter unit 420 to minimize the flow resistance of the discharge water.

6 shows a configuration in which the drain pipe 120 and the cartridge body are detachably coupled to each other in a snap manner, unlike FIG. 5.

Referring to the drawings, for this purpose, the drain pipe 130, a snap groove 131 is formed on the inner circumferential surface, and the cartridge body 440 is formed to protrude from the outer circumferential surface, and when inserted into the drain hole 110, the snap groove 131 It is configured to include a snap projection 414 is fitted to the coupling.

Here, the snap projection 414, the cartridge body 440, the first inclined surface 4141 formed on the front surface in the direction of being inserted into the drain hole 110, and the cartridge body 440 is separated from the drain hole 110 It is configured to have a second inclined surface 4142 formed on the front of each.

First, the first inclined surface 4141 is located on the front side of the direction in which the cartridge body 440 is inserted into the drain pipe 130, and when the cartridge body 440 is inserted into the drain pipe 130, the opposite side of the snap groove 131 It is configured to limit the insertion depth in the drain pipe 130 of the snap projection 414 in contact with the side.

Here, the first inclined surface 4141 is configured to limit the insertion depth in the drain pipe 130 of the cartridge body 440, the cartridge body 440 is predetermined when the cartridge body 440 is inserted into the drain pipe 130 Do not insert more than the depth of.

Here, the larger the inclination angle α of the first inclined surface 4141, the easier it is to limit the position of the cartridge body 440 in the drain pipe 130. Therefore, the inclination angle α is the cartridge body 440 described above. A ramp large enough to achieve the purpose of limiting the insertion depth is possible.

Next, looking at the second inclined surface 4142, the second inclined surface 4142 is located on the front surface of the direction in which the cartridge body 440 is separated from the drain hole 110, and the cartridge body 440 is discharged by the water pressure. When detached from the drain pipe 130, it is configured to limit the separation by contacting the facing side of the snap groove 131.

Here, the discharge water pressure is a value that is changed by the shape and material of the snap projection 414, which means the water pressure at which the cartridge body 440 is withdrawn from the drain pipe 130.

In other words, the second inclined surface 4142 is a configuration that determines the degree of force that the cartridge body 440 deviates from the drain pipe 130 by the discharge water pressure, that is, the discharge water pressure, and the contact resistance is changed according to the inclination angle. The discharge water pressure is different.

Thus, the filter cartridge 400c can adjust the inclined angle β of the second inclined surface 4142 to control the discharged water pressure that deviates from the hydraulic pressure of the discharged water, and the size of the inclined angle can be set according to the design.

As described above, the filter cartridge 400c can secure the fastening force by limiting the insertion depth of the cartridge body 440 in the drain pipe 130 by the first inclined surface 4141 of the snap protrusion 414 , Through the second inclined surface (4142) is also configured to control the degree of departure according to the discharge water pressure.

On the other hand, when the discharge water pressure is high, the filter cartridge 440c, when the flow rate of the discharge water increases, such as a heavy rain, flood, etc., the discharge of the discharge water is not smooth, and the back pressure and the water pressure on the wall 100 increase, thereby increasing the wall ( 100) may collapse.

For this reason, the filter cartridge 400c limits the insertion depth so as to be located at the set insertion depth and improves the fastening force, but it is preferable to facilitate separation from the discharge water pressure.

To this end, referring to FIG. 7, the inclination angle α of the first inclined surface 4141 is greater than the inclined angle β of the second inclined surface 4142 relative to the outer peripheral surface of the cartridge body 410 (α> β It is preferably configured to have.

First, the first inclined surface 4141 is an inclined surface located in the front of the direction (a direction) in which the filter cartridge 400c is inserted into the drain pipe 130, and the inclination angle α of the first inclined surface 4141 is Increasing the inclination of the inclination with respect to the direction into which the drain pipe 130 is inserted, effectively restricting the movement of the filter cartridge 400c in the a direction and ensuring the fastening force, as well as the correctness of the filter cartridge 400c It should be located in the fastening position.

On the other hand, the second inclined surface 4142 is an inclined surface located in front of the direction (b direction) in which the filter cartridge 400c is drawn out by the discharge water pressure, and the inclination angle β of the second inclined surface 4142 is a drain pipe ( The slope of the drawn out from 130) is gentle, so that the filter cartridge 400c in the b direction is easy to move, so that it is easy to deviate from the overpressure of the rear surface of the wall structure.

Furthermore, the snap protrusion 414 is formed of an elastic material, and if the water pressure of the discharge water in the drain hole 110 is greater than or equal to a set value, it is preferably elastically deformed so that the filter cartridge 400a is detached from the drain hole 110. In addition, a silicone material or the like may be applied as the elastic material.

The snap groove 131 has a first groove inclined surface 132 and a second groove inclined surface having inclination angles corresponding to the first inclined surface 4141 and the second inclined surface 4142 of the snap protrusion 414 as illustrated. 133). However, it is a matter of course that the inclination angles of the first groove inclined surface 132 and the second groove inclined surface 133 may be configured to be the same, respectively.

On the other hand, the cartridge body (440a) may be selected to change the discharge water pressure of the cartridge body (440a) removed in the field in consideration of the climate and the like.

Referring to FIG. 8, first, the cartridge body 440a is formed with a split snap projection 415 on a portion of the outer circumference of the cartridge body 440a.

In the drawing, two split snap projections 415 are formed on the outer circumferential surface of the cartridge body 440a, and each is positioned symmetrically with respect to the center of the cartridge body 440a. In addition, the split snap protrusions 415 each have a length corresponding to 1/4 of the outer peripheral surface of the cartridge body 440a.

The snap groove is formed to be divided into a plurality of regions along the inner circumferential surface of the drain pipe 140, and is formed in correspondence with the number and location of the split snap projections 415. In the drawing, the snap groove is formed by being divided into four equal divisions along the inner circumferential surface of the drain pipe 140 corresponding to the two divided snap projections 415.

In addition, the snap grooves are formed so that the inclined angles of the surfaces contacting the second inclined surface of the divided snap protrusions 415 are formed in different divided areas, and the inclined angles are β1 for each area. 141 and second snap grooves 142 each having an inclination angle of β2 are formed.

Accordingly, by the rotation of the cartridge body 440a, the split snap projection 415 is selectively fitted to the first snap groove 141 to be interviewed and the second snap groove 142 to be removed by different withdrawal water pressures. .

That is, the split snap protrusion 415 is selectively fitted to the first snap groove 141 and the second snap groove 142 regions having different inclination angles according to the rotation of the cartridge body 440a. When the projection 415 is inserted into the first snap groove 141, it is removed by the corresponding withdrawal water pressure, and when the split snap projection 415 is rotated into the second snap groove 142, the withdrawal pressure different from the above Is removed.

According to the above, the filter cartridge is configured such that the split snap protrusion 415 is selectively fitted into the first snap groove 141 and the second snap groove 142 to be removed by different withdrawal water pressures, thereby causing flood or heavy rain during the rainy season. If it is expected that the withdrawal water pressure needs to be lowered, the operator rotates the cartridge body 440a in the field without replacing or removing the filter cartridge so that the split snap projection 415 fits into the corresponding snap groove. Water pressure can be lowered.

On the other hand, the first snap groove 141, the second snap groove 142, the drainage pipe 120 is divided into regions evenly divided the inner circumferential surface, the divided snap projection 415, the first snap groove (141) ) And the second snap groove 142 are alternately formed to correspond to the divided region.

In this example, as shown, the first snap groove 141 and the second snap groove 142 are equally divided into four regions, and the regions are divided, and the divided snap projections 415 are symmetrical to each other so as to correspond thereto. Although the case formed by the split snap protrusions 415 is illustrated, this is also possible in various other forms as an embodiment.

Furthermore, on the front of the filter cartridge, a display unit (not shown) in which the withdrawal water pressure is displayed is formed so that an operator can check the difference in the withdrawal water pressure according to the rotation direction of the cartridge body 440a. Such a display unit may display the degree and location of the withdrawal pressure by a number or symbol on the front of the cartridge body 440a which can be checked by the operator, and various shapes such as molding or stickers are attached when the cartridge body 440a is manufactured. Formats can be applied.

Although the present invention has been described with reference to the embodiments shown in the drawings, these are merely exemplary, and those skilled in the art will understand that various modifications and equivalent other embodiments are possible therefrom. Therefore, the true technical protection scope of the present invention should be determined by the technical spirit of the appended claims.
