Description

Permeable grating for blocking odor with excellent drainage performance {Grating for blocking of odor with improved drainage}

This relates to a permeable grating that is installed in a roadside sewer or drain to drain rainwater. More specifically, it relates to a permeable grating that has high rainwater drainage performance and can effectively block bad odors.

Generally, drains are connected to the lower part of both edges of the road, and grating in the form of a grid is installed on the upper part of the drain. Grating allows water such as rainwater or melted snow to flow into the drain through grid-shaped drainage holes, and allows pedestrians to pass safely without falling into the drain.

However, since the drain where the grating is installed is located adjacent to the sidewalk, cigarette butts and other small trash discarded by pedestrians flow into the drain through the drainage holes in the grating, while leaves and fruits of street trees also flow into the drain, causing such trash to end up in the drain. A strong odor generated by decay along with stagnant water may be discharged to the outside through the drain hole.

As such, an example of a grating that can block odors to prevent odors generated from drains from flowing back is Republic of Korea Patent No. 10-2540332 ‘Grating for blocking odors’. Registered Patent No. 10-2540332 is a grating that can be stably used for a long time regardless of the inflow of dust by supporting the rotating opening and closing member rotatably using the lower rotating frame, upper rotating frame, and rotating wire without using a separate hinge. is starting.

However, according to this prior art, the drainage hole is opened only when a pressure greater than the weight of the weight coupled to the end of the weight coupling plate of the pivoting opening and closing member is applied to the protruding hill, so when a small amount of rain falls, the drainage hole is closed. As the water remains in this state, smooth drainage is not achieved. In addition, the protruding hill protrudes higher than the drain hole, causing problems for pedestrians and causing accidents, such as a woman's shoe heel getting caught in the drain hole.

The goal is to propose a permeable grating that allows smooth drainage regardless of the amount of rain that falls, while also effectively blocking odors from drains.

Figure 2 is a view from above of the automatic opening and closing block 20 according to this embodiment, and Figure 3 shows the upper surface of the automatic opening and closing block 20 of Figure 2 facing the floor to show the features of the configuration in more detail. This is a diagram showing an exploded view of the true state.

Each automatic opening and closing block 20 is formed in the shape of a square box with a rainwater inlet 211 formed on the upper surface, and the rainwater inlet 211 is formed by a rotating opening and closing plate 22 rotatably installed at the bottom of the rainwater inlet 211. ) is opened to drain rainwater, or the rainwater inlet 211 is closed by the rotating opening and closing plate 22 to block bad odors from below.

The opening/closing case 21 is formed in the shape of a rectangular box with an open lower surface consisting of an upper plate and four side plates. The four side plates are connected to each other at right angles and are composed of a left plate, right plate, front plate, and rear plate. The left and right plates have a longer length than the front and rear plates, and form the length of the opening and closing case 21.

The front side of the upper plate of the opening and closing case 21 is provided with a rainwater inlet 211 formed through the upper plate, and the rainwater flowing in through the rainwater inlet 211 is drained into the drain through the open lower surface of the opening and closing case 21. . The shape of the rainwater inlet 211 is not particularly limited, but it is preferably formed as a square in order to efficiently use the space on the top plate of the opening and closing case 21.

A shaft holder 212 is protruding from the lower surface of the upper plate of the opening and closing case 21, so that the fastening rod 23, which becomes the rotation axis of the rotating opening and closing plate 22, is fixed at a certain height within the opening and closing case 21. 23) is supported. The wheel base portion 212 protrudes at a certain depth from the lower surface of the upper plate of the opening and closing case 21 and forms a curved portion bent downward. In this embodiment, the wheel holder 212 may be formed by bending a square plate protruding from the lower surface of the upper plate of the opening and closing case 21 back toward the lower surface of the upper plate, as shown in FIG. 3.

In addition, a person skilled in the art will easily understand that the shaft holder 212 protrudes at a certain depth from the lower surface of the upper plate of the opening and closing case 21 and can be formed in various shapes to stably support the fastening rod 23. will be. For example, the shaft holder 212 protrudes from the lower surface of the upper plate of the opening and closing case 21 and may be a plurality of U-shaped rings arranged parallel to each other.

A side through-hole 213 is formed in at least one of the left and right plates of the opening and closing case 21 at a position facing the shaft support portion 212. The fastening rod 23 is inserted into the wheel holder 212 through the side through hole 213 from the left or right side of the opening and closing case 21 and is mounted on the wheel mount 212. .

The rotating opening/closing plate 22 is formed in the shape of a bent square plate, and rotates inside the opening/closing case 21 to open or close the rainwater inlet 211 of the opening/closing case 21. The rotating opening/closing plate 22 is bent along a bend line 214 so as to protrude upward, and rotates in the vertical direction within the opening/closing case 21. At this time, the bending line 214 is formed perpendicular to the longitudinal direction of the rotary opening and closing plate 22.

The front and rear sides of the rotary opening/closing plate 22 according to this embodiment move in opposite directions up and down with respect to the bending line. As shown in Figure 4a, with the front side of the rotary open and close plate 22 raised upward and the rear side lowered, the front upper surface of the rotary open and close plate 22 is arranged to completely cover the rainwater inlet 211, thereby preventing water from the drainage channel. Blocks bad odor.

Meanwhile, as shown in Figure 4b, in a state where the front side of the rotary opening and closing plate 22 is lowered and the rear side is raised upward, the front side of the rotating opening and closing plate 22 is away from the lower surface of the upper plate of the opening and closing case 21, Accordingly, rainwater flows in through the rainwater inlet 211 and is drained into the drainage channel through the open lower surface of the opening and closing case 21.

In this embodiment, the front side of the rotary opening and closing plate 22 has a ridge ( 215) is provided. The raised portion 215 is inserted into the rainwater inlet 211 when the rainwater inlet 211 is closed and blocks the rainwater inlet 211, thereby more reliably blocking bad odors from the drain.

In one embodiment of the present invention, the raised portion 215 is raised to a height less than the thickness of the upper plate of the opening and closing case 21, so that it does not protrude outside the upper plate of the opening and closing case 21 when the rainwater inlet 211 is closed. Accordingly, it is easy to fasten the porous cover 25 to the opening and closing case 21. In this embodiment, the raised portion 215 is raised by the thickness of the upper plate of the opening and closing case 21, so that the upper surface of the opening and closing case 21 is flat when the rainwater inlet 211 is closed.

Meanwhile, the rotating opening/closing plate 22 is penetrated through an area including a portion of the bend line 214, thereby forming a fitting hole 216. When the rotating opening and closing plate 22 is inserted into the opening and closing case 21, the shaft holder 212 of the opening and closing case 21 passes through the insertion hole 216 of the rotating opening and closing plate 22, and the rotating opening and closing plate 22 It protrudes from the bottom of the. If the size of the fitting hole (216) is too large, the rotating opening/closing plate (22) may shake back and forth and the center of gravity may not be aligned, so smooth opening and closing of the rainwater inlet (211) may not be achieved, and the size of the fitting hole (216) may be insufficient. If it is too small, the space required for rotation may not be secured and the rotation of the rotary plate 22 may not be smooth, so the size of the fitting hole 216 is set small enough to not interfere with the rotation of the rotary plate 22. It is desirable.

The fastening rod 23 is disposed in the opening and closing case 21 so as to be perpendicular to the longitudinal direction of the opening and closing case 21, and is rotated so that the bending line 214 of the rotating opening and closing plate 22 is located on the fastening rod 23. By supporting the plate 22, the rotation of the rotary opening/closing plate 22 becomes the center.

In an embodiment of the present invention, the fastening rod 23 is inserted into the opening and closing case 21 through the side through hole 213 formed in at least one of the left and right plates of the opening and closing case 21, and the rotating opening and closing plate ( It is mounted on the curved portion of the shaft holder 212 protruding from the lower surface of 22). Figure 4 is a side cross-sectional view of the automatic opening and closing block 20 according to an embodiment of the present invention.

Referring to FIG. 4, inside the opening and closing case 21, the shaft holder 212 of the opening and closing case 21 penetrates the fitting hole 216 of the rotating opening and closing plate 22 to the lower surface of the rotating opening and closing plate 22. It protrudes, and the fastening rod 23 is inserted into the curved part of the shaft holder 212 protruding from the lower surface of the rotary opening and closing plate 22, so that the rotary opening and closing plate 22 can rotate inside the opening and closing case 21. are combined. In other words, the automatic opening and closing block 20 according to this embodiment can be used to open and close the rotating opening and closing plate 22 by simply placing the rotating opening and closing plate 22 inside the opening and closing case 21 and inserting one fastening rod 23. 21), so it is very convenient as it does not require separate screw fastening.

In this embodiment, the fitting hole 216 may be formed symmetrically around the bend line 214 of the rotary opening and closing plate 22. As the fitting hole 216 is formed in a symmetrical shape around the bending line 214 of the rotating opening and closing plate 22, when the fastening rod 23 is fastened, the bending line 214 of the rotating opening and closing plate 22 is connected to the fastening rod. It is located on (23), and accordingly, the front and rear sides of the bending line 214 can smoothly rotate in opposite directions with the rotating opening/closing plate 22 using the fastening rod 23 as the rotation axis.

In this way, the rotating opening and closing plate 22 is connected to the opening and closing case using the shaft holder 212 protruding from the lower surface of the upper plate of the opening and closing case 21, the fitting hole 216 of the rotating opening and closing plate 22, and the fastening rod 23. Rotatably coupling to (21) simplifies the structure for rotation of the rotary opening/closing plate (22), which has the effect of lowering the failure rate and manufacturing cost of the device.

The weight 24 has a certain mass and is installed at the rear of the rotary opening/closing plate 22 so that a greater force of gravity acts on the rear of the rotary opening/closing plate 22 than on the front. Accordingly, the rear side of the rotating opening/closing plate 22 rotates downward and the front side upward around the fastening rod 23 as a rotation axis due to the weight of the weight 24, and accordingly, the rainwater inlet 211 is automatically opened. It is closed. Accordingly, rainwater is drained through a plurality of water permeable blocks (30).

On the other hand, when a force greater than the weight of the weight 24 is applied downward to the front of the rotary opening and closing plate 22, the front of the rotary opening and closing plate 22 rotates downward and the rear rotates upward, and the rainwater inlet 211 is opened. It is open. In an embodiment of the present invention, the rotating opening/closing plate 22 can open the rainwater inlet 211 by rotating due to the weight of the rainwater flowing into the rainwater inlet 211. More specifically, as the weight of the rainwater flowing into the rainwater inlet 211 increases, the rear side of the rotary opening and closing plate 22 rotates upward, so that the weight of the accumulated rainwater increases with the weight 24. If the weight exceeds, the front side of the rotary opening/closing plate 22 moves downward and the rainwater inlet 211 is opened. Accordingly, rainwater is drained through a plurality of automatic opening and closing blocks (20) and a plurality of water permeable blocks (30).

In one embodiment of the present invention, the weight 24 may be made of a bolt 241 and a nut 242. When the bolt 241 penetrates the thickness of the rotary opening and closing plate 22 at a point on the rear side of the rotating opening and closing plate 22, the nut 242 is screwed to the bolt 241, thereby attaching the bolt to the rotating opening and closing plate 22. 241) and nut 242 can be fixed. At this time, the bolt 241 has a length that is more than twice the thickness of the nut 242, so that a plurality of nuts 242 can be fastened to the bolt 241.

As the number of nuts 242 fastened to the bolt 241 increases, the weight due to the weight 24 increases, which means that when a larger amount of rainwater flows in, the rainwater inlet 211 is opened, and the bolt As the number of nuts 242 fastened to 241 decreases, the weight due to the weight 24 decreases, which allows the rainwater inlet 211 to be opened even when a smaller amount of rainwater flows in. Therefore, rainwater can be efficiently drained by adjusting the number of nuts 242 fastened to the bolts 241 by comprehensively considering the geographical environment in which the permeable grating 1 is installed, season, rainfall amount, etc.

In an embodiment of the present invention, the amount of rainwater flowing into the permeable grating 1 or the rainwater inlet 211 is determined by whether the rotary opening and closing plate 22 can be rotated, and the weight 24 ), the amount of rain that can lift the rear of the rotating opening and closing plate (22) located below can be called large, and the rear of the rotating opening and closing plate (22) located below is lifted by the weight (24). The amount of rain that cannot be raised can be called low. Therefore, in this embodiment, the amount of rainwater flowing into the permeable grating 1 or the rainwater inlet 211 is determined based on the weight of the weight 24 coupled to the rear of the rotary opening and closing plate 22. You can.

The porous cover 25 is formed as a square plate with a plurality of rainwater passing holes 251, and is covered with the opening and closing case 21 so as to cover the upper surface of the opening and closing case 21, so that it is larger than each rainwater passing hole 251. Prevents objects from being inserted into the rainwater inlet (211).

In this way, the porous cover 25 with a plurality of rainwater passing holes 251 is coupled to the opening and closing case 21 so as to cover the upper plate of the opening and closing case 21 where the rainwater inlet 211 is formed, so that rainwater drains smoothly. While maintaining this, it is possible to prevent pedestrians' shoe heels from getting caught in the rainwater inlet (211) or foreign substances such as cigarette butts from flowing into the sewer through the rainwater inlet (211).

In this embodiment, each rainwater passing hole 251 may be formed in an oval shape with a long axis and a short axis. In this way, when each rainwater passage hole 251 is formed in an oval shape, the area of the hole for rainwater to pass through is secured, and the width in the short axis direction is small, so that foreign substances such as shoe heels or cigarette butts are prevented from entering each rainwater passage hole 251. ) is very effective as it can be prevented from passing through. In one embodiment of the present invention, each rainwater passage hole 251 may have a major axis length of 2 cm and a minor axis length of 1.5 cm.

The porous cover 25 may be formed in a shape in which the front and rear ends of the square plate are bent vertically downward, and the opening and closing case (21) has the bent front and rear ends facing the front and rear plates of the opening and closing case (21), respectively. ) can be coupled to the opening/closing case (21) by inserting it into the opening/closing case (21).

In one embodiment of the present invention, at least one fastening protrusion 252 protruding inward is formed at the inner bottom of each of the bent front and rear ends of the porous cover 25. Each fastening protrusion 252 supports the front and rear plates of the opening and closing case 21 below the front and rear plates of the opening and closing case 21 while the porous cover 25 is inserted into the opening and closing case 21. Prevents the opening/closing case (21) from escaping downward from the porous cover (25).

Each water permeable block 30 is formed in the shape of a square bar in which a plurality of particles are mixed and tangled together, and rainwater is drained downward through the pores formed between the plurality of particles. Each water permeable block (30) is made up of a plurality of types of particles entangled together by bonds, and a gap communicating upward and downward is formed between these particles, so that rainwater drains into the lower drain through each water permeable block (30). .

Each permeable block 30 can be formed by mixing multiple types of stones and bonding them together. In one embodiment of the present invention, the stone making up each permeable block 30 may be soybean gravel, elvan gravel, and volcanic stone. At this time, the particle size of soybean gravel, elvan gravel, and volcanic stone is 5 to 10 mm.

Meanwhile, a two-component binder containing urethane may be used as a bond for bonding the stones of each permeable block 30. In this embodiment, the bond may be a two-component binder in which 12 parts by weight of a base material made of urethane resin and 5.5 parts by weight of a urethane curing agent are uniformly stirred.

Each pervious block 30 is first mixed with 70 to 76 parts by weight of soybean gravel, 5 to 15 parts by weight of elvan gravel, and 5 to 15 parts by weight of volcanic stone, then 8 to 10 parts by weight of bond is added to 100 parts by weight of the mixed stone and then stirred. After creating the permeable block dough, it can be manufactured by molding the generated permeable block dough into a square bar shape and hardening it.

In one embodiment of the present invention, the permeable block dough is filled into each drainage hole 11 of the permeable grating (1) and the permeable block dough protruding from the top of the permeable grating (1) is removed to remove the upper surface of the permeable grating (1). By flattening and then hardening, the pitcher block dough can be molded into a square bar shape. In this way, filling and hardening the permeable block dough into each drainage hole 11 of the permeable grating 1 allows the molding of the permeable block 30 and the installation of the permeable block 30 to be performed at the same time, making the work efficient. In addition, there is no need to manufacture a separate frame to manufacture a permeable block that fits the size of each drain hole (11) of the permeable grating (1), thereby reducing costs.

In this way, each water-permeable block 30 has improved durability by mixing stone and bond in an appropriate amount, and has water permeability by forming pores communicating upward and downward between the stones. Meanwhile, the stones are clustered together to prevent water from sewage. Suppresses odors from being released to the outside of the permeable grating (1).

The lower net 40 is formed in a mesh network shape and is installed on the lower surface of the grating main body 10 as shown in FIG. 5. The lower net 40 supports each automatic opening and closing block 20 and each water permeable block 30 at the bottom of the grating main body 10 to prevent each automatic opening and closing block 20 and each water permeable block 30 from falling to the bottom. While supporting each automatic opening and closing block (20) and each water permeable block (30), the water flowing in through each automatic opening and closing block (20) and each water permeable block (30) is allowed to drain into the sewer through the holes in the mesh network. . In one embodiment of the present invention, the lower net 40 may be manufactured to prevent corrosion by plating zinc on a mesh net made of iron and coating the outer surface of the zinc plating layer with a rust preventive agent. At this time, the rust preventive agent preferably contains phosphate and potassium phosphate salt.

Permeable grating (1) according to an embodiment of the present invention has an automatic opening and closing block (20) inserted into some of the drainage holes (11) of the plurality of drainage holes (11) of the grating body (10), and a plurality of drainage holes (11) of the grating body (10). A permeable block (30) is inserted into the remaining drain hole (11), and an automatic opening/closing block (20) or a permeable block inserted into the grating body (10) is installed depending on the amount of rainwater flowing into the permeable grating (1). Rainwater is drained through

Looking at the operation of the permeable grating (1) according to an embodiment of the present invention with reference to FIG. 5, which shows the permeable grating (1) according to an embodiment of the present invention, and FIG. 6, which shows a side cross-sectional view of FIG. 5, the operation of the permeable grating (1) according to an embodiment of the present invention is as follows. same. Figure 5 shows a portion of the grating body 10 omitted to show the lower net 40 installed below the grating body 10.

Rainwater from rainfall or snowfall flows toward the permeable grating (1) installed on the road surface. Rainwater flowing toward the permeable grating (1) is located on each automatic opening and closing block (20) and each permeable block (30) of the permeable grating (1). In this case, when the amount of rainfall or snowfall is small, each automatic opening and closing block (20) The rotating opening and closing plate 22 closes the rainwater inlet 211 without rotating. Therefore, rainwater flowing into the permeable grating (1) is drained into the sewer through the pores of each permeable block (30).

Meanwhile, as the amount of rainwater flowing into the permeable grating (1) increases and the weight of the rainwater increases, the rotating opening and closing plate (22) of each automatic opening and closing block (20) rotates so that the front side moves downward and the rear side moves upward. Accordingly, the rainwater inlet 211 of the opening and closing case 21 is opened, and the rainwater is drained into the sewer through each automatic opening and closing block 20 and each water permeable block 30.

In this embodiment, the weight of the rainwater for rotating the rotary opening and closing plate 22 of each automatic opening and closing block 20 is proportional to the weight of the weight 24 installed on the rear of the rotating opening and closing plate 22.

In this way, by installing a plurality of automatic opening and closing blocks 20 and a plurality of water permeable blocks 30 on the grating main body 10, it is possible to efficiently drain rainwater according to the amount of rainwater and block odor from the sewer.

More specifically, when the amount of rainwater flowing into the permeable grating (1) is large, the rainwater can be drained more quickly by using a plurality of permeable blocks (30) and a plurality of automatic opening and closing blocks (20) to drain the rainwater. You can keep the road surface comfortable.

On the other hand, when the amount of rainwater flowing into the permeable grating (1) is small, the rainwater inlet (211) of each automatic opening and closing block (20) is not opened, and the rainwater flowing into the permeable grating (1) is discharged into each permeable block (30). Even in the case of a small amount of rainwater, drainage is performed through the permeable block 30 and the road surface can be maintained comfortably.

Therefore, the permeable grating (1) according to this embodiment has the problem of not draining a small amount of rainwater generated when the automatic opening and closing block (20) is inserted into all drain holes (11) of the grating body (10) and the grating body (10). When the water permeable block 30 is inserted into all the drainage holes 11 of (10), all the problems of difficulty in quickly draining a large amount of rainwater generated can be resolved.

Hereinafter, the present invention will be described through the following examples. However, the following examples are for illustrating the present invention in detail, and do not limit the scope of the present invention to the following examples.

In the permeable grating (1) of the embodiment, all drain holes (11) of the grating main body (10) are empty, that is, the plurality of permeable blocks (30) and the plurality of permeable blocks (30) are not installed, but are the same as the embodiment. A pitcher grating (1) was produced.

(Comparative Example 2)

The pervious grating (1) of the example was manufactured in the same manner as the example, except that a plurality of permeable blocks (30) were installed in all drain holes (11) of the grating body (10).

(Comparative Example 3)

The permeable grating (1) of the example was manufactured in the same manner as the example, except that a plurality of automatic opening and closing blocks (20) were installed in all drain holes (11) of the grating main body (10).

(Comparative Example 4)

In the permeable grating (1) of the embodiment, each permeable block (30) is manufactured by molding permeable block dough prepared by mixing 75 parts by weight of soybean gravel, 10 parts by weight of elvan gravel, 15 parts by weight of volcanic stone, and 2 parts by weight of bond. Permeable grating (1) was manufactured in the same manner as in the example, except that.

(Comparative Example 5)

In the permeable grating (1) of the embodiment, each permeable block (30) is manufactured by molding permeable block dough prepared by mixing 75 parts by weight of soybean gravel, 10 parts by weight of elvan gravel, 15 parts by weight of volcanic stone, and 30 parts by weight of bond. Permeable grating (1) was manufactured in the same manner as in the example, except that.

(Test Example 1)

After installing the permeable grating (1) manufactured according to the examples and each comparative example on the road surface, 5L of water was poured from the top of the ground at once and the time for the water to completely drain was measured. The test results are shown in Table 1 below.

Example Comparative Example 1 Comparative example 2 Comparative Example 3 Comparative Example 4 Comparative Example 5 Drain time (seconds) 2.7 0.1 6 1.9 2.2 3.7

Referring to Table 1, Comparative Example 1, in which no block was installed in the drain hole 11 of the grating main body 10, was quickly drained as soon as water flowed in. On the other hand, the grating according to the embodiment is Comparative Example 3 in which automatic opening and closing blocks 20 are installed in all drain holes 11 of the grating main body 10, and Example 2 in which 2 parts by weight of bond is contained in each water permeable block 30. It took some time compared to , but you can still see that drainage was completed relatively quickly. On the other hand, Comparative Example 2, in which water permeable blocks 30 were installed in all drain holes 11 of the grating main body 10, took more than twice the time compared to the example, and Comparative Example 5, where each water permeable block 30 had a high bond content, Additionally, it took more time to drain compared to the example. Meanwhile, in the case of Comparative Example 4, the drainage speed was excellent, but it was confirmed that there was a problem with the durability of each permeable block 30 because stones were separated from each permeable block 30 due to rainwater.

From this, it was confirmed that when a large amount of rainwater flows in, it is more advantageous for drainage when there are many automatic opening and closing blocks (20) in the drainage hole (11) of the grating main body (10), and the water contained in each water permeable block (30) If there are too many bonds, drainage is difficult because pores are not formed well. If there are too few bonds, it is advantageous for drainage, but there are problems with durability.

(Test Example 2)

After installing the permeable grating (1) manufactured according to the examples and each comparative example on the road surface, 500 ml of water was poured from the top of the ground, and the time for the water to completely drain was measured. The test results are shown in Table 2 below.

Example Comparative Example 1 Comparative example 2 Comparative Example 3 Comparative Example 4 Comparative Example 5 Drain time (seconds) 0.6 0.1 0.5 Doesn't drain 0.4 65

Referring to Table 2, Comparative Example 1, in which no block was installed in the drain hole 11 of the grating main body 10, was quickly drained as soon as water flowed in. On the other hand, in Comparative Example 3, where automatic opening and closing blocks (20) were installed in all drain holes (11) of the grating main body (10), the amount of rainwater flowing in was small and the rotating opening and closing plate (22) did not rotate, so the rainwater was not drained.

Comparative Example 2, in which permeable blocks 30 were installed in all drain holes 11 of the grating main body 10, drained water faster than the example in which automatic opening and closing blocks 20 were installed in some drain holes 11, and each permeable block 30 Comparative Example 5, which had a high bond content, also took a lot of time because drainage was not smooth.

From this, it was confirmed that when a small amount of rainwater flows in, it is more advantageous for drainage when there are many permeable blocks 30 in the drainage holes 11 of the grating main body 10.

(Test Example 3)

After installing the permeable grating (1) manufactured according to the examples and each comparative example on the road surface, the odor was measured using an odor meter at a point 10 cm above the permeable grating (1). The test results are shown in Table 3 below.

Example Comparative Example 1 Comparative example 2 Comparative Example 3 Comparative Example 4 Comparative Example 5 Odor level (ppm) 0.007 5 0.008 0.006 0.2 0.004

Referring to Table 3, in Comparative Example 1, in which no block was installed in the drain hole 11 of the grating main body 10, the odor from the sewer was discharged directly to the ground, and the odor level was measured to be very high. In the case of the permeable grating (1) of Examples, Comparative Examples 2, Comparative Examples 3, and Comparative Examples 5, the drainage hole (11) is blocked by the permeable block (30) or automatic opening/closing block (20), which blocks odor very well. I was able to confirm. As soon as the water came in, it drained away quickly. However, in the case of Comparative Example 4, where the bond content of the permeable block 30 is low, it can be confirmed that the odor is not blocked smoothly by the permeable block 30, resulting in a somewhat unpleasant odor.

Looking at Test Examples 1 to 3 comprehensively, when the amount of rainwater flowing in is large, the automatic opening and closing block 20 effectively drains the rainwater, and when the amount of rainwater flowing in is small, the water permeable block 30 effectively drains the rainwater. You can see that rainwater is being drained.

In the case of a general grating in which nothing is installed in the drain hole 11 of the grating main body 10, it showed high drainage performance regardless of the amount of rainwater flowing in, but it cannot block odor from the sewer, so when it is actually installed on the road surface, it is very large. It has been confirmed that it can cause discomfort.

Accordingly, the excellence of the permeable grating 1 of the example was proven in that it blocks bad odors from the sewer while exhibiting high drainage performance regardless of the amount of rainwater.
