Description

Drainage trap structure}

The present invention relates to a drainage overpass for collecting and discharging miscellaneous wastewater from a bathroom floor, and more specifically, to a drainage overpass with a multi-stage water-sealed structure that is sealed in multiple stages to prevent odor from flowing back.

Generally, a drainage overpass is installed on the floor of a bathroom or toilet to discharge waste water, and is connected to a drain pipe so that waste water can be discharged to the outside through the drainage overpass. The drainage pipe method is divided into sub-floor piping and layered piping, and the layered piping method is advantageous in terms of inter-floor noise and maintenance. Here, the sub-floor piping method is a construction method of discharging water to the lower floor by penetrating the floor slab layer of a bathroom or toilet, etc., while the layered piping method is a construction method of discharging water onto the floor slab layer of the relevant floor. When drain pipes are laid out and buried with concrete using the layered piping method, if the floor slab layer becomes thick, a large amount of concrete must be poured and finished, which increases construction costs and increases work time, which reduces economic feasibility. In addition, in the layered piping method, when mortar is injected and finished after the floor slab layer is brought down to secure space for discharging the drain pipe, a large amount of mortar must be injected and finished, thereby increasing the construction cost. Accordingly, it is desirable to ensure that the floor slab layer or mortar layer is not thicker than an appropriate range, but in the case of a drainage overpass installed on the floor slab layer of a bathroom or toilet, it must have a water-sealed structure to prevent odors from flowing back, so it can only be increased. There is a limit to reducing the thickness of the floor slab layer or mortar layer. To solve this problem, a drainage overpass with a low height and effective water sealing is needed, and a multi-stage water seal structure is attracting attention as a solution.

As a prior art regarding the multi-stage water seal structure, an example is disclosed in Republic of Korea Patent No. 10-1902493. In the case of the above prior art, a method of lowering the overall height of the drain trap is proposed by expanding the area of the water seal and reducing its height using a two-stage water seal member. However, when simply water sealing in multiple stages, air pockets are formed inside the water seal between the multiple stages, causing the problem that miscellaneous water cannot be discharged smoothly. In order to solve this problem, the height of the water sealing member must be increased, which increases the thickness of the floor slab layer or mortar layer.

First, the terminology used to describe drained beef as a preferred embodiment according to the present invention will be explained. In the field of the present invention, the terms "bongsu" or "water bong" are used interchangeably to refer to the use of a drain trap to allow water to accumulate in a part of a drain pipe, preventing odors such as sewage gas from flowing back or passing through. For convenience of understanding and explanation, the water that drains from the floor of a bathroom or toilet is called "miscellaneous water", and the term "subong" is used to refer to the water that is partially accumulated in the drainage area to prevent odor from flowing back. The terms “upward” and “downward” are used in relation to the arrangement structure of the drainage overpass. “Downward” refers to a direction in the horizontal direction toward which miscellaneous water falls, and refers to a direction opposite to the direction in which miscellaneous water falls in the horizontal direction. Additionally, the term “oblique direction” is used to refer to a direction slanted to the direction in which miscellaneous water flows in or falls. In the field of the present invention, there may be various examples of forming a water seal in two or more stages in the internal water collection space of a drainage overpass, but for convenience of explanation and understanding, a drainage overpass in which two or two-stage water seals are formed continuously is used. This will be explained with an example.

Hereinafter, with reference to the attached drawings, the drainage meat as a preferred embodiment according to the present invention will be described in more detail.

Figure 1 is an external perspective view showing a drainage hexagon as a preferred embodiment according to the present invention, Figure 2 is an exploded perspective view showing a drainage hexagon as a preferred embodiment according to the present invention, and Figure 3 is a preferred embodiment according to the present invention. As an example, this is a bottom perspective view showing a drainage overpass.

Referring to Figures 1 to 3, as a preferred embodiment according to the present invention, the drainage overpass (1) includes a drain trough (10), an inner member (20), a strainer screen (30), a packing member (40), and a drain. A cover 50 is provided.

The drain gutter 10 has a gutter body 110 in a recessed shape to provide a water collection space, and a rectangular cover frame whose cross-section is expanded lateral from the upper edge of the gutter body 110. It has (120). The cover frame 120 has an overall rectangular shape and has a support surface portion 121 and an edge portion 122. The edge portion 122 has a stepped shape that protrudes upward from the support surface portion 121 corresponding to the shape of the drain cover 50, and the support surface portion 121 is formed in a plate shape and supports the drain cover 50. It has a support portion (121b) and a chamfering portion (121a) that is formed to be inclined in two stages inside the support portion (121b) and has a height lower than the upper surface of the support portion (121b). The chamfering portion 121a is located overlapping the side of the edge portion 122, and the support portion 121b is located on the corner side of the edge portion 122. In addition, the drain cover 50 is a plate-shaped member that is shaped to fit the edge portion 122 of the cover frame 120, and its edge is bent downward and a plurality of drain holes 50a are provided on the inside. do. Accordingly, when the drain cover 50 is disposed on the cover frame 120, the drain cover 50 is placed on the support portion 121b of the support surface portion 121 and is separated from the chamfering portion 121a. A separation space is provided between the cover frame 120 and the cover frame 120.

The drain trough 10 is coupled to the internal member 20 so that a water collection space can be formed therein, and for this purpose, the internal member 20 is fixed to the boundary between the cover frame 120 and the gutter body 110. Mounting protrusions 124 for are disposed radially, and a cut end 110a having a stepped shape is provided inside the gutter body 110 for seating the inner member 20. Here, the packing member 40 is disposed between the internal member 20 and the cut end 110a to prevent the odor from flowing back.

The inner member 20 is made of an annular plate corresponding to the annular cut end 110a, and an inlet H1 of a relatively large diameter is provided in its center so that wastewater can flow in. Since it is desirable to allow miscellaneous water to flow smoothly through the inlet (H1), the shape of the inner member (20) is funnel-shaped, and the inner member (20) passes through the mounting protrusion (124) to be combined with the drain trough (10). A mounting groove (20a) is disposed at the edge of (20) corresponding to the mounting protrusion (124). And after the drain cover 50 is placed on the cover frame 120, an upwardly protruding support protrusion 23 is radially disposed on the inner member 20 so as to support the drain cover 50 when pressed from above. . Here, it is preferable that the upward projection of the support protrusion 23 be at the same height as the upper surface of the supporting portion 121b of the cover frame 120 and higher than the upper surface of the chamfering portion 121a.

The internal member 20 must allow miscellaneous water to flow in through the inlet H1. However, if foreign matter such as hair flows in, the discharge of miscellaneous water is not smooth, so to prevent this, a filtering screen is installed at the inlet H1. It is desirable to place 30). For this purpose, a downwardly stepped seating end 20b is provided at the inlet H1 of the inner member 20. In addition, it is preferable that the seating end 20b allows the strainer 30 to move or rotate laterally, and this is achieved by making the width of the seating end 20b slightly larger than the width of the strainer 30. It can be.

Figure 4 shows a strainer applied to a drainage overpass as a preferred embodiment according to the present invention, (a) is a perspective view of the strainer and (b) is a plan view of the strainer.

Referring to FIG. 4, the mesh 30 has a structure in which a plurality of inclined blade pieces 33 are radially connected between the hub 31 on the center side and the rim portion 35 on the edge side. The inclined blades 33 are disposed at an angle with respect to the inflow direction or falling direction of the miscellaneous water, and allow the miscellaneous water to flow in a diagonal direction when it flows downward. It is desirable that the filtering screen 30 allows wastewater to flow in a diagonal direction and more effectively filters foreign substances such as hair. This can be achieved by allowing the strainer 30 to freely rotate according to the flow of miscellaneous water at the seating end 20b. For this purpose, the area of the inclined blade 33 is increased from the central hub 31 to the edge rim 35 in the direction in which miscellaneous water flows into or falls into the inlet H1, that is, when viewed from a plan view. In the example shown, the inclined blade 33 is twisted at an angle of 45° at the hub 31 and is integrally connected to the rim portion 35. This can also be done by changing the twist angle more freely, such as spiral or helical.

Referring to FIG. 3, the inner member 20 is provided with two downward partition walls 25 and 27 arranged on its lower side to be spaced apart from each other in the radial direction. The downward partition walls 25 and 27 protrude downward from the lower side of the internal member 20. Looking more specifically, the downward partition wall 25 on the inner side communicates with the inlet H1 and extends downward in a cylindrical shape. The outer downward partition 27 is radially spaced from the inner downward partition 25 and extends downward from the lower side of the inner member 20 in a cylindrical shape. Here, the protruding length of the downward partition walls 25 and 27 is set at a height lower than that of the gutter body 110 so that miscellaneous water can flow between the bottom surface 112 of the drain trough 10.

Figure 5 is a plan view showing a drainage gutter applied to a drainage overpass as a preferred embodiment according to the present invention, and Figure 6 is a plan view showing a drain gutter applied to a drainage overpass as a preferred embodiment according to the present invention in the longitudinal direction along the central axis of the outlet. It is a partial cross-sectional view shown by cutting, and Figure 7 is a side view shown from the outlet side of a drainage gutter applied to a drainage overpass as a preferred embodiment according to the present invention.

Referring to Figures 2 and 5 to 7, the drain trough 10 is surrounded by a cylindrical side wall 111 and its bottom surface 112 so as to be combined with the internal member 20 to provide a water collection space. It has a gutter body 110 that is open at the top. And since miscellaneous water must be discharged from the water collection space, an oval-shaped discharge port (H2) is provided on the side wall (111). Here, the outlet H2 may be circular, square, or other various shapes known in the field of the present invention, but an oval shape is preferred as an example of a non-circular shape with a horizontal width greater than the vertical height in order to lower the height of the drain trough 10. do. In addition, since the outlet (H2) must be connected to an external drain pipe (P: see Figure 8) to allow miscellaneous water to flow, an oval-shaped drain connector 113 is connected to the outlet (H2) on the side wall (111). ) is integrally connected to.

On the bottom surface 112 of the drain trough 10, a dispersion protrusion 114, an upward partition wall 115, 117, and a slope drain 118 are sequentially provided from the center thereof.

The distributing protrusion 114 is, for example, conical in shape so that miscellaneous water can be dispersed and flow smoothly from the center to the outer periphery, and is located at the central axis of the inlet H1 of the internal member 20 or the downward partition 25.

The upward bulkheads 115 and 117 are arranged radially spaced apart from each other in the dispersing protrusion 114 and have a cylindrical shape corresponding to the downward bulkheads 25 and 27 of the inner member 20, and the bottom surface 112 It protrudes upward from the top, but has an open upper side so that waste water can flow beyond the top. In the example shown, it protrudes at a height that is spaced apart from the lower side of the internal member 20 without contacting it. Here, the upward bulkheads (115, 117) are preferably connected to the bottom surface (112) or the dispersion protrusion (114) with rounded curved portions (115a, 117a) to reduce turbulence in the miscellaneous water and allow it to flow smoothly. . In addition, the upward bulkheads 115 and 117 are located spaced apart from each other on the inner and outer sides in the radial direction. When combined with the inner member 20, the downward bulkheads 25 and 27 of the inner member 20 move upward. By being alternately positioned between the partition walls 115 and 117 and spaced apart from each other, they are arranged so that the inner water seal and the outer water seal can be formed by miscellaneous drainage.

Meanwhile, in the case of the upper protruding ends of the upward bulkheads 115 and 117, it is desirable to have a height gradient so that when miscellaneous water overflows, it can bypass and overflow around the outlet (H2) rather than toward the outlet (H2). For this purpose, the As an example, bank portions 115b and 117b that protrude in relatively high steps are provided in a portion facing the outlet H2. If the width of the bank portions (115b, 117b) is excessively large, the drain trough (10) may become wider or the flow of miscellaneous water may be obstructed, so it is preferably 0.7 to 1.3 times the width (w) of the outlet (H2). It is desirable to set it to a width of the ratio. In addition, among the upward partition walls 115 and 117, the upward partition wall 115 located on the inner side has an open upper side so that the waste water flowing in through the inlet H1 can overflow, and at the same time, the upward partition wall 115 can allow the waste water to flow in and out. It is preferable that a through-hole-shaped bypass passage 115h is provided on the lower side where miscellaneous water is submerged.

In addition, the slope drain 118 is located on the outside of the upward bulkhead 117 or on the gutter body 110 so that the miscellaneous drainage that overflows through the upward bulkhead 117 and flows around it is inclined with a height difference toward the outlet H2. It is provided on the side wall 111. In this case, as the potential energy of the miscellaneous water is changed to kinetic energy, the flow rate increases toward the outlet (H2), which is desirable for smooth discharge of the miscellaneous water. Here, the slope drain 118 may be inclined in one direction in terms of its slope, but it is preferable to be inclined in both directions with the point opposite to the outlet H2 as the highest point. In this case, miscellaneous wastewater collides in both directions at the discharge port (H2), which may hinder the flow of miscellaneous water to the discharge port (H2). Therefore, it is desirable to arrange the outlet guide port 119 at the lowest point of the slope drain 118 or at a position intersecting the outlet H2. For this purpose, the outlet guide port 119 is formed in a shape whose cross-section is gradually reduced toward the outlet H2. Looking more specifically, its side is curved to reduce the flow resistance of miscellaneous wastewater, and its upper surface is slope-cut. For example, it has the shape of a bird's beak.

As a preferred embodiment according to the present invention, we will look at the effects of drained meat.

Referring to Figures 1 and 2, as an example according to the present invention, the packing member 40 is inserted around the outer circumference of the inner member 20, and its mounting groove 20a is connected to the mounting protrusion 124 of the drain trough 10. ) and then seated on the incised end (110a) of the drain trough (10). When the internal member 20 is rotated, the internal member 20 is caught by the radially arranged mounting protrusion 124 and is coupled to the drain trough 10. In this case, only the inlet (H1) and outlet (H2) are open, and the drain trough (10) and the inner member (20) are sealed with the packing member (40), so that there is space between the inlet (H1) and the outlet (H2) therein. A water collection space is provided.

Referring to Figures 2 to 4, as an example according to the present invention, when the strainer mesh 30 is inserted into the inlet H1 of the inner member 20, it is located at the stepped seating end 20b of the inner member 20. . In this case, since the seating end 20b is formed to be somewhat larger than the holding net 30, the holding net 30 can move or rotate laterally. In addition, the inclined blades 33 of the filter net 30 are inclined in the direction of inflow or fall of miscellaneous water and have a larger projection area from the center to the edge. Accordingly, when miscellaneous water flows in through the inlet (H1), it can flow smoothly in a diagonal direction as it flows in along the inclined wing piece 33, and the rapid flow and collision of miscellaneous water can reduce the inflow of air into foam. Flexible hair can be effectively filtered out as the inclined wing piece 33 orients or rotates in reaction to the flow of miscellaneous water.

Referring to FIGS. 2 and 3 and FIGS. 5 and 6, as an example according to the present invention, a drain cover 50 is placed on the cover frame 120 of the drain trough 10, and for this purpose, the cover frame 120 A support surface portion 121 and an edge portion 122 are provided corresponding to the shape of the drain cover 50. In the case of the present invention, the support surface portion 121 is provided with a chamfering portion 121a along with a support portion 121b. In normal cases, foreign substances are filtered out by the drain cover 50 and miscellaneous waste water flows into the drain hole 50a, and at the same time, it is supported even when stepped on from the outside. To this end, the edge of the drain cover 50 is bent. It is designed in a way that distances it from the cover frame (120). According to this conventional method, the drain cover 50 is supported over the entire edge portion 122 of the cover frame 120. However, since an outlet H2 must be provided on the side wall 111 of the drain trough 10, a cover frame 120 of sufficient thickness or height to resist external force must be secured. For this reason, when it is desired to lower the height of the drainage overpass (1) that can be applied to a layered slab structure, a separate reinforcing structure is provided in the area where the outlet (H2) is provided, or the thickness or height of the cover frame 120 is adjusted. Because it has to be enlarged, the manufacturing process becomes complicated and there are limits to lowering the height. In order to solve this problem, in the case of the present invention, a chamfering portion 121a is provided at a height lower than the upper surface of the support portion 121b, and the chamfering portion 121a and the support portion 121b are separated to form the cover frame 120. The drain cover 50 can be supported on the support portion 121b of the square corner, and damage due to external force is prevented by placing the discharge port H2 below the chamfering portion 121a, so it has a thin thickness. It can be made at a low height and the outlet (H2) can be made larger depending on the drainage capacity. Moreover, in the case of the present invention, the inner member 20 is provided with a radial support protrusion 23, and the support protrusion 23 protrudes upward higher than the chamfering portion 121a, so that it passes through the drain cover 50. Even so, direct influence on the chamfering portion 121a can be eliminated and damage caused by external force can be reduced. Moreover, since the influence of external force on the outlet H2 can be reduced, the shape of the outlet H2 can be changed in various ways, and in particular, it can be formed into an oval shape as a non-circular shape with a horizontal width greater than the vertical height. It is very beneficial in lowering the height of the drainage ridge.

Figure 8 is a cross-sectional view showing the installation state of a drainage overpass as a preferred embodiment according to the present invention.

Referring to Figure 8, in a preferred embodiment according to the present invention, the drainage overpass (1) is placed on the bottom of the concrete slab layer (S) of a bathroom or toilet, connected to the drain pipe (P), and finished with mortar to form a mortar layer (M). Form and install by attaching the tile (T).

Referring to Figures 2 and 8, when waste water flows in from the floor of a bathroom or toilet, it flows in through the drain hole 50a of the drain cover 50. In the case of the internal member 20, it is formed in a funnel shape, so the waste water flows in. It can flow to the inlet (H1).

Referring to FIGS. 2, 4, and 8, as seen previously, miscellaneous water does not fall directly into the inlet H1 due to the slanted blades 33 of the strainer 30, but rather flows in a diagonal direction along the slanted blades 33. As it flows in, it flows smoothly from the center to the periphery along the dispersion protrusions 114 and curved portions 115a provided on the bottom surface 112 of the drain trough 10 while rotating within the water collection space while reducing the flow of air into the foam. .

Referring to FIGS. 2, 4, and 8, miscellaneous water passes between the first downward partition wall 25 inside the inner member 20 and the bottom surface 112 of the gutter body 110, and the drain gutter 10 ), some of it flows through the bypass passage 115h on the lower side, and gradually fills up and overflows due to the upper opening. And it passes between the second downward partition wall 27 on the outside of the internal member 20 and the bottom surface 112 of the gutter body 110, and reaches the second upward partition wall 117 on the outside of the drain gutter 10. Also, as it gradually fills up and opens at the top, it overflows. The miscellaneous water overflowing the second upward bulkhead 117 outside the drain trough 10 flows along the slope drain 118 and is guided by the outlet guide port 119 to the outlet H2 and the drain connection pipe ( 113), and is discharged to the outside through the drain pipe (P).

Referring to FIGS. 2, 6, and 8, when wastewater flows from the floor of a bathroom or toilet, the first downward bulkhead 25 inside the internal member 20 and the first inner downward partition wall 25 of the drain gutter 10 The inner water seal is formed by the upward bulkhead 115, and the outer water seal is formed by the second downward bulkhead 27 outside the inner member 20 and the second upward bulkhead 117 outside the drain trough 10. is formed At this time, an air pocket (A) is formed between the inner and outer downward bulkheads (25, 27) related to the inner water seal because they are sealed by miscellaneous water. In the case of this air pocket (A), as wastewater falls or hits through the inlet (H1), air flows into the foam, and as the air accumulates, the air pressure increases, causing water stagnation that prevents wastewater from being discharged from the floor of the bathroom or toilet. It is pointed out. It is especially pointed out in the case of multi-stage water seals that, in order to solve the problem of air pockets (A), the height from the floor of the toilet to the inlet (H1) must be increased, which is the height of the drain gutter (10) or drain overpass (1). There is a problem with the increase in height, and the height of the upward bulkheads 115 and 117 may be lowered, but in this case, the height of the drainage overpass cannot be lowered because there is a risk of water seal destruction. However, in the case of the present invention, since the bypass path (115h) is provided, the air pressure of the air pocket (A) is overcome at the beginning of the cycle when a large amount of waste water accumulates from the floor of the bathroom or toilet, and the upward bulkhead is formed along with the bypass path (115h). Miscellaneous wastewater may be discharged beyond (115), and even if the amount of wastewater on the toilet floor is small in the latter half of the cycle and cannot go beyond the upward bulkhead (115) due to the air pressure of the air pocket (A), the wastewater is discharged through the bypass path (115h). Since water can flow, the height of the drainage outlet (1) can be lowered while preventing water from pooling on the floor of the bathroom or toilet. In addition, in the case of the present invention, the inclined blades 33 allow the miscellaneous water to flow in a diagonal direction rather than straight down and flow while rotating, and the occurrence of turbulence in the miscellaneous water is reduced by the dispersion protrusion 114 and the curved portion 115a. By doing so, it is possible to reduce the increase in air pressure in the air pocket (A) due to air flowing into the foam from the inlet (H1).

In addition, in order for waste water to be smoothly discharged from the floor of a bathroom or toilet without stagnation, it is necessary to increase the capacity for waste water to be discharged from the outlet (H2) and to ensure that waste water is discharged quickly and without clogging. As seen above, in the case of the present invention, the support portion 121b of the cover frame 120 is configured to support the external load, and the side wall 111 where the outlet H2 is located is configured to receive less load. The discharge port (H2) can be made large, and since it is formed in a non-circular oval shape, the drainage capacity through the discharge port (H2) can be increased. In addition, in the case of the present invention, a slope drain 118 that is inclined with a height difference is provided, so as the miscellaneous water flows through the slope drain 118, the flow rate increases, allowing it to quickly flow to the outlet (H2). Here, it is preferable that the miscellaneous water overflowing through the upward bulkhead 117 is located at a high point rather than a low point so that its potential energy is converted into kinetic energy in the slope drain 118 and the flow rate increases, and the outlet (H2) is located. If mixed wastewater overflows through the upward bulkhead (117) at this point, it may collide with the mixed wastewater flowing into the slope drain (118) and the flow to the outlet (H2) may be interrupted, so it may be directed to the upward bulkhead (117) in the area where the outlet (H2) is located. It is desirable to prevent wastewater from immediately overflowing. For this purpose, the upward bulkheads 115 and 117 according to the present invention are provided with bank portions 115b and 117b that are stepped and protrude relatively high, so that when reaching the bank portions 115b and 117b, miscellaneous water bypasses and overflows around the bank portions (115b and 117b). Since it flows and joins the miscellaneous water above it at the high point of the slope drain 118, the flow to the outlet (H2) is smoother. Moreover, in the drain gutter 10, a slope drain 118 is provided in both directions around the most distant point of the side wall 111 facing the outlet H2, so that miscellaneous drainage flows from both directions. When reaching (H2), miscellaneous water may collide with each other, causing flow resistance. However, in the case of the present invention, at the lowest point of the slope drain 118, which intersects or is located at the outlet H2, there is a bird-beak-shaped outlet guide port 119 that protrudes toward the outlet H2, is curved, and has a slope-cut upper part. It is provided so that miscellaneous wastewater can naturally flow in from both directions of the slope drain 118 and be quickly discharged through the oval-shaped outlet (H2).

As described above, the drained beef stock according to the present invention has been described and illustrated in more detail as a preferred embodiment. However, it should be understood as being for the convenience of explanation and understanding of the multiplex according to the present invention, and should not be construed as limited to the above-described shape, shape, reference sign, accessory or part, and other documents should be used contrary to the description of the present invention. Therefore, it should not be construed as limiting, and since various modifications or changes can be made without departing from the technical spirit of the present invention, the scope of rights of Baejae Yukga according to the present invention should be determined by the scope of the attached patent claims.

Claims (9)

An inlet and an outlet are provided so that wastewater can flow in and discharge from the floor of the bathroom or toilet, and the water collection space between the inlet and the outlet is watered by wastewater between the downwardly protruding downward bulkhead and the upwardly protruding upward bulkhead. In the drainage overpass where at least two water seals are formed, including an inner water seal formed adjacent to the inlet side and an outer water seal formed adjacent to the outlet side in the relative relationship between the inlet and the outlet,
The upward partition associated with the formation of the inner water seal is,
A drainage overpass having an open shape at the top so that the wastewater flowing in through the inlet can overflow, and a bypass passage in the shape of a hole at the lower side where the wastewater is submerged so that the wastewater can flow in and out. According to claim 1,
The upward bulkhead is
A drainage overpass, characterized in that a height gradient is formed so that miscellaneous water can overflow by bypassing the outlet side rather than around it. According to claim 1,
A drainage overpass, characterized in that it is provided with a sloped drainage channel arranged inclinedly with a height difference so that the sewage overflowing the upward bulkhead increases the flow rate toward the outlet. According to claim 1,
In the slope drainage,
A drainage overpass, characterized in that it has an outlet guide port protruding toward the outlet. According to claim 1,
A drainage overpass, characterized in that it further comprises; a strainer mesh body having inclined blades disposed at an angle with respect to the inflow direction or falling direction of the miscellaneous water flowing in through the inlet. According to claim 5,
The inclined wing section is,
When viewed from the direction in which the inlet flows in or falls, the drainage overpass is characterized in that the area located on the edge of the inlet is larger than the area located on the center side of the inlet. According to claim 1,
Drain cover provided with multiple drain holes;
a cover frame including a support portion on which the drain cover is placed, and a chamfering portion formed at a lower height than the upper surface of the support portion so as to be separated from the drain cover;
a drain trough integrally connected to the cover frame, the outlet provided on a side wall located below the chamfering portion, and an upward partition wall disposed upward on the bottom surface; and
A drainage overpass, characterized in that it includes; an internal member in which the inlet is provided, a downward partition wall is disposed downward, and a water collection space is provided therein by being combined with the drainage trough. According to claim 7,
The internal member is,
A drainage hexagon, characterized in that it has a support protrusion that protrudes upward higher than the chamfering portion. According to claim 7,
The outlet is,
A drainage landfill characterized by a non-circular shape with a horizontal width greater than the vertical height.
