Description

[Technical field]

[0001] The present invention relates to a collection structure and a collection tool. [Background technology]

[0002] Japanese Patent Application Laid-Open No. 2023-18540 discloses an invention relating to a catchment basin provided in a drainage ditch of an artificial turf ground.

[0003] As disclosed in the publication, an artificial turf ground is, for example, paved with an asphalt layer on a crushed stone base as a base layer, and synthetic resin artificial turf is laid on top of that. The gaps in the artificial turf are filled with rubber chips. The artificial turf ground gently slopes towards the periphery. A U-shaped drainage ditch is provided around the periphery of the artificial turf ground. The open upper surface of the drainage ditch is covered with, for example, a drain cover or grating with a water drop hole. The drain cover and grating are removable. The drainage ditch is provided with multiple catchment basins. The catchment basin is provided with an inlet through which water flows in from the drainage ditch and an outlet through which water flows out. The outlet is provided at the bottom of the catchment basin and is connected to a final catchment basin by a connecting pipe. The outlet of the final catchment basin is connected to an outlet pipe, and is configured so that wastewater flows out from the outlet pipe to a public sewer system.

[0004] The catchment basin disclosed in the publication includes a water inlet, a water outlet, and a water-permeable filter provided between the inlet and the outlet. The filter does not substantially block the passage of water flowing in from the inlet, but has voids large enough to block the passage of artificial turf debris and rubber chips that flow in with the water.

[0005] In this embodiment, the inside of the catchment basin is divided into two by a permeable filter provided approximately halfway up in the height direction. In other words, the inside of the catchment basin is divided into an upstream section above the filter and a downstream section below the filter (see FIG. 7). The catchment basin has an inlet through which water flows in from the drainage ditch, and an outlet through which water flows out. In other words, the filter is provided between the inlet and the outlet. The outlet is connected to the downstream section of the downstream catchment basin by a connecting pipe. Furthermore, the outlet of the final catchment basin is connected to a discharge pipe.

[0006] It is also said that it is desirable for the filter to have pores large enough to prevent the passage of silica sand with a particle size exceeding 0.8 mm. It is also said that porous water-permeable concrete boards and palm fiber nonwoven fabric boards can be used as filters with pores. It is also said that it is desirable for this porous water-permeable concrete board to have pores with a diameter of 0.4 mm or more and 3.7 mm or less. Palm fiber nonwoven fabric boards have a density of 49.5 kg / m 3 More than 60.5kg / m 3 It is considered desirable that: [Prior art documents] [Patent documents]

[0007] [Patent Document 1] JP 2023-18540 A Summary of the Invention [Problem to be solved by the invention]

[0008] Incidentally, not only microplastics that flow out of the artificial turf pitch, but also materials that flow in from the plants and soil around the artificial turf pitch can enter the drainage ditches and catchment basins of artificial turf grounds along with rainwater. The microplastics and materials that get into the rainwater are captured by the filter. As the amount of captured materials increases, the drainage performance of the filter deteriorates. If the drainage capacity of the drainage ditches and catchment basins decreases and rainwater flows in beyond their capacity, the catchment basins and drainage ditches will overflow, increasing the risk of flooding and damage to the artificial turf facilities and exterior structures. For this reason, the filters need to be cleaned and replaced frequently. [Means for solving the problem]

[0009] The collection structure disclosed herein includes a catchment basin, at least one drainage groove connected to the catchment basin, and a collection tool installed in the catchment basin to which the drainage groove is connected. The collector is configured as a semi-cylindrical or tubular mesh body with an open top and a cross-sectional shape that allows it to slide along the drain. The collector is installed so that one end is placed in the drain and a portion of it extends from the drain into the catch basin. Effect of the Invention

[0010] The collection structure and collection tool disclosed herein are easy to maintain. [Brief description of the drawings]

[0012] The collection structure and collection tool disclosed herein will be described below with reference to the drawings. The present invention is not limited to the following embodiments. Each drawing is drawn diagrammatically and does not necessarily reflect the actual product. Each drawing shows only an example, and does not limit the present invention unless otherwise specified. Members and parts that perform the same function are appropriately given the same reference numerals, and duplicated explanations are omitted. In this specification, a notation such as "X to Y" indicating a numerical range means "X or more and Y or less" unless otherwise specified.

[0013] <Artificial Turf Ground 1> Fig. 1 is a plan view of an artificial turf ground 1 to which a collection structure 10 is applied. As shown in Fig. 1, the artificial turf ground 1 is a ground on which artificial turf has been laid as described above, and has a gentle slope that becomes lower towards the periphery. Drainage facilities such as a catchment basin 12 and a drainage ditch 11 are provided around the periphery of the artificial turf ground 1.

[0014] In the artificial turf ground 1, wastewater containing microplastics such as artificial turf fragments and rubber chips flows into a drain 11. The wastewater further flows from the drain 11 into a catchment basin 12. The collection structure 10 is a structure for collecting microplastics such as artificial turf fragments and rubber chips that contain the wastewater. It should be noted that the facility in which the collection structure 10 is employed is not limited to the artificial turf ground 1 unless otherwise specified. The collection structure 10 can be employed in the catchment basin 12 and drain basin 11 of various drainage facilities, not limited to the artificial turf ground 1. Here, the collection structure 10 will be described using the drainage facility of the artificial turf ground 1 as an example.

[0015] <Collection structure 10> Fig. 2 is a plan view showing the capturing structure 10. Fig. 3 is a vertical cross-sectional view showing the capturing structure 10. As shown in Figs. 2 and 3, the capturing structure 10 includes a drainage ditch 11, a catchment basin 12, and a collector 13. The capturing structure 10 is a structure for capturing garbage such as microplastics in the drainage ditch 11 and the catchment basin 12. Here, the catchment basin 12 and the drainage ditch 11 may be existing facilities or may be facilities to be installed in the future.

[0016] <Drain 11> The drainage ditch 11 is a side gutter. In the artificial turf ground 1, the drainage ditch 11 is provided so as to surround the periphery of the artificial turf ground 1 in plan view, as shown in FIG.

[0017] <Catchment Basin 12> The catchment basin 12 is provided at intervals in the drainage ditch 11. The catchment basin 12 is a facility that is recessed deeper than the drainage ditch 11. The catchment basin 12 has a required capacity so that the water in the drainage ditch 11 can flow in smoothly even when the drainage ditch 11 has a large amount of discharge. At least one drainage ditch 11 is connected to the catchment basin 12. A connection port 12a1 to which the drainage ditch 11 is connected is provided at the top of the depression 12a of the catchment basin 12. An outlet 12a2 may be provided at the bottom of the depression 12a of the catchment basin 12. A connecting pipe 21 buried underground may be connected to the outlet 12a2. The connecting pipe 21 is configured so that wastewater flows out to an external public sewerage system 60 (see FIG. 1) or the like.

[0018] In this way, the catchment basin 12 is used at the location where the drainage ditch 11 is connected. The catchment basin 12 can generally be used as a connecting basin to change the angle of the gutter, for example, when water flowing in a longitudinal gutter needs to be diverted to the opposite side of the road. The catchment basin 12 can also be used to connect a waterway of a different structure, such as a gutter and a drainage pipe. The catchment basin 12 can also be used as a connecting basin when the angle of the gutter needs to be changed. When a gutter is constructed on an inclined surface, the cross section of the gutter is at an angle to the basin. Since the connecting cross section of the waterway becomes larger, a rectangular or larger catchment basin can be used in this case.

[0019] For example, around the artificial turf ground 1, the catchment basin 12 is buried in the area where the drainage ditches 11 are connected along a straight line or where the drainage ditches 11 intersect, and the two drainage ditches 11 are connected to the catchment basin 12 along the axis that intersects in the catchment basin 12. There are various types of catchment basin 12. For example, in the type shown in Figures 2 and 3, the catchment basin 12 is provided with a connection port with an open upper edge at the part where the two drainage ditches 11 are attached. In addition, a frame material 15 for attaching a lid 14 is attached to the top of the catchment basin 12, and the lid 14 is attached to the step 15a of the frame material 15. The lid 14 of the catchment basin 12 can be fixed to the frame material 15 with bolts, although not shown. The lid 14 can be made of steel or concrete. A grating is attached to the drainage ditches 11 as appropriate.

[0020] <Collecting tool 13> The collector 13 is a tool that is installed in the catch basin 12 to which the drain 11 is connected. The collector 13 is composed of a semi-cylindrical or cylindrical mesh body that is open at the top. The collector 13 may have a cross-sectional shape that allows it to slide along the drain 11.

[0021] FIG. 4 is a perspective view of the collector 13. FIG. 5 is a side view of the collector 13. In the embodiment shown in FIG. 4 and FIG. 5, the collector 13 may be composed of a frame body 13a and a mesh material 13b. Here, the frame body 13a may be a frame that supports the mesh material 13b along a cross-sectional shape along the bottom and both sides of the drainage ditch. The frame body 13a may be assembled with rods, for example, as shown in FIG. 4 and FIG. 5, and the mesh material 13b may be attached along the frame body 13a. Here, at least a part of the mesh material 13b may be provided detachably with respect to the frame body 13a.

[0022] The frame 13a is composed of a shaft member 13a1 along the length direction, a shaft member 13a2 along the width direction, and a shaft member 13a3 along the cross-sectional shape of the gutter. The cross-sectional shape of the collector 13 may have a cross-sectional shape that can slide along the drainage gutter 11 as shown in FIG. 5. In this embodiment, the cross-sectional shape of the collector 13 is formed by a shaft member 13a3 along the cross-sectional shape of the gutter. The shaft member 13a3 gradually narrows toward the bottom along the cross-sectional shape of the gutter, and an R is provided at a portion 13a4 along the corner of the bottom. The shaft member 13a1 along the length direction and the shaft member 13a2 along the width direction may be provided at the upper edge, the middle portion in the height direction, and the bottom, respectively. In this embodiment, the net member 13b covers the bottom and both sides of the collector 13. The both ends and the upper portion of the collector 13 are open without the net member 13b attached. The collector 13 is not limited to being configured as a semi-cylindrical net body with an open top. Although not shown, the collector 13 may be configured as a cylindrical net body. In other words, the collector 13 may further have an upper wall having a filtering function.

[0023] In this embodiment, the rods constituting the frame 13a and the net 13b are preferably made of stainless steel. Alternatively, a resin having high weather resistance and required mechanical strength, such as polycarbonate or polyvinyl chloride, may be used. If a resin collector 13 is used, it is preferable to replace it before it deteriorates and produces microplastics.

[0024] The collector 13 is installed so that one end is installed in the drainage groove 11 and a part of it extends from the drainage groove 11 into the water collection basin 12. In the embodiment shown in Figs. 2 and 3, two drainage grooves 11 consisting of U-shaped grooves are connected along a straight line so as to straddle the square water collection basin 12 that is wider than the drainage grooves 11. The collector 13 is attached to the two drainage grooves 11 connected to the water collection basin 12 along such a straight line so as to straddle the water collection basin 12. In this manner, the collector 13 may have a cross-sectional shape that follows the bottom and both sides of the drainage groove 11. In this embodiment, the width of the collector 13 becomes smaller toward the bottom side. There may be a slight gap between the bottom and both sides of the drainage groove 11, and the collector 13 may have a shape that generally follows the bottom and both sides of the drainage groove 11. The collector 13 may have a cross-sectional shape that can slide along the drainage groove 11. In this embodiment, the collector 13 has a semi-cylindrical U-shaped cross section to match the cross section of the U-shaped gutter, but is not limited to this. For example, if the cross section of the drainage gutter is U-shaped (a shape in which the bottom wall and side wall are connected without a curved surface), the cross section of the collector 13 may have a semi-cylindrical U-shaped cross section to match the cross section of the drainage gutter.

[0025] In this embodiment, the collector 13 is inserted into a catchment basin 12 with an inner dimension of 60 cm x 60 cm, bridges the drainage ditch 11 on the opposite side of the insertion portion, and is installed in a form in which the collector 13 stands on its own on the drainage ditch 11 alone. From this viewpoint, the collector 13 is preferably made to have a height of about 20 cm and a length of about 80 cm. The frame 13a of the collector 13 should have a required rigidity. The rod material used for the frame 13a should be, for example, a stainless steel round bar (Φ6 mm). The higher the height of the collector 13, the better. For example, the height of the collector 13 should be 1 / 2 or more of the depth of the drainage ditch 11, preferably 2 / 3 or more of the depth of the drainage ditch. On the other hand, the height of the collector 13 should be determined so that the collector 13 can be accommodated under the frame material 15 on which the lid 14 of the catchment basin 12 is placed. From this perspective, when the drain 11 is a U240 side drain having a depth of 240 mm, the height of the collector 13 is preferably about 180 mm to 200 mm.

[0026] <Net material 13b> The mesh material 13b is a mesh material having a required gap. In this embodiment, the stainless steel mesh has a double structure to ensure strength, and a mesh material with a 9 mm mesh (wire diameter 1.0 mm) opening is attached to the outside of the frame body 13a, and a mesh material made of a 2 mm mesh (wire diameter 0.57 mm) is attached to the inside. In this way, the mesh material 13b may have a structure in which the mesh materials 13b1 and 13b2 are attached to the inside and outside of the frame body 13a, respectively. In this case, the mesh material attached to the outside of the frame body 13a may be thicker in diameter than the mesh material attached to the inside, and may be made of a mesh material with high wear resistance. In this embodiment, the mesh materials 13b1 and 13b2 are fixed to the frame body 13a by welding or the like.

[0027] The structure of the net material is not limited to the one exemplified here. Many of the drains 11 have a standardized cross-sectional shape according to the JIS standard. For this reason, it is economical to create a collector 13 of a standard size according to the standard cross-section of the drain 11. The net material 13b2 on the outside of the frame body 13a may be fixed to the frame body 13a by welding or the like, and the net material 13b1 on the inside of the frame body 13a may be attached to the frame body 13a in a detachable and replaceable manner. The net material 13b1 on the inside of the frame body 13a may be fixed to the frame body 13a by welding or the like, and the net material 13b2 on the outside of the frame body 13a may be attached to the frame body 13a in a detachable and replaceable manner. Both the net material 13b1 on the inside of the frame body 13a and the net material 13b2 on the outside of the frame body 13a may be attached to the frame body 13a in a detachable and replaceable manner. When the inner mesh material 13b1 and the outer mesh material 13b2 are detachably attached to the frame body 13a, they may be fastened with a fastener such as a retaining ring.

[0028] <Maintenance of collection tool 13> The collector 13 can slide along the drain 11. Therefore, when attaching the collector 13 to the drain 11, the collector 13 is attached to one of the two drains 11 connected to the catchment basin 12. The collector 13 is then slid along a straight line so as to straddle the catchment basin 12. The collector 13 is then slid toward the catchment basin 12, straddling the catchment basin 12 and crossing it over to the other drain basin 11, and both ends of the collector 13 are placed on the drains 11 on both sides, as shown in Figures 2 and 3, and both ends of the collector 13 are installed in the two drains 11. This allows the collector 13 to be stably attached to the catchment basin 12.

[0029] In this case, even if the lid 14 is attached to the catchment bin 12, the collector 13 can be attached to the drain ditch 11 and the catchment bin 12 with the lid 14 attached to the catchment bin 12. Also, with the lid 14 attached to the catchment bin 12, the collector 13 can be slid and pulled out toward one of the drain ditch 11. Therefore, with the lid 14 attached to the catchment bin 12, the collector 13 can be easily removed from the drain ditch 11 and the catchment bin 12. In this way, the collector 13 can be replaced with the lid 14 attached to the catchment bin 12. Since the collector 13 can be replaced without removing the lid 14 from the catchment bin 12, maintenance is easy, cleaning frequency can be increased, and drainage capacity can be easily ensured.

[0030] <Capturing microplastics in wastewater> Wastewater flowing through the drain 11 passes through the collector 13 from the upstream drain 11 and enters the catchment basin 12. Microplastics that can be captured by a 2 mm mesh net (wire diameter 0.57 mm) on the inside, such as garbage contained in the wastewater, pieces of artificial turf (pile fragments), and rubber chips, are captured by the collector 13 when they enter the catchment basin 12 from the drain 11. In order to capture finer microplastics, a finer filter may be replaceably attached to at least a part of the inner surface of the collector 13 on the inside of the collector 13. In this case, finer microplastics that cannot be captured by the mesh material 13b of the collector 13 can also be captured. As described above, the collector 13 is installed using the space of the catchment basin 12, so that a large area can be secured to function as a filter. Therefore, the collector 13 is likely to maintain the required drainage capacity as a whole even if some parts become clogged.

[0031] According to the inventor's calculations, if the drain 11 is a so-called U-shaped drain with an upper edge opening width of 240 mm, a general-purpose drain with a drain width of 240 mm, the cross-sectional area up to a height of 20 cm is approximately 447 cm 2 In contrast, the inner surface of the collector 13 at the portion spanning the catchment basin 12 is approximately 3462 cm 2 The collector 13 has a filter function (a U-shaped cross-section filter in this embodiment) with an area equivalent to the cross-sectional shape of the drain 11, located above the catchment basin 12. The inner surface of the collector 13 that follows the cross-section functions as a filter. Therefore, clogging is unlikely to occur. Also, a sufficiently large area can be obtained for the cross-section of a general-purpose gutter with a gutter width of 240.

[0032] In this way, when two drainage ditches are connected to the catchment basin 12, the collector 13 may be attached to the catchment basin 12 so as to span the connection ports of the two drainage ditches 11. In other words, both ends of the collector 13 may be supported by the openings of the two drainage ditches 11 connected to the catchment basin 12. The collector 13 installed here may capture microplastics, fallen leaves, soil, and sand depending on the amount of drainage. This gradually impedes drainage. However, the collector 13 is attached to the top of the catchment basin 12. In the catchment basin 12, there is a large space under the net material 13b of the collector 13. Therefore, the catchment basin 12 has a required space for storing drainage, and drainage from the catchment basin 12 to the downstream is unlikely to be blocked. Since drainage from the catchment basin 12 to the downstream is unlikely to be blocked, overflow water overflowing from the catchment basin 12 is unlikely to occur.

[0033] 6 to 9 are plan views showing, by way of example, other forms of the catchment basin 12 to which the drainage ditch 11 is connected. In the form shown in FIG. 6, two drainage ditch 11 are connected at right angles to a square catchment basin 12 wider than the width of the U-shape of the drainage ditch 11 via the catchment basin 12. In the form shown in FIG. 7, the catchment basin 12 is a rectangular catchment basin 12 having the same width as the width of the U-shape of the drainage ditch 11, and two drainage ditch 11 are connected along a straight line via the catchment basin 12. In the form shown in FIG. 8, the catchment basin 12 has the same width as the width of the U-shape of the drainage ditch 11, is an orthogonal catchment basin 12 in which the catchment basin 12 itself is bent at a right angle, and two drainage ditch 11 are connected at right angles via the catchment basin 12. In the form shown in FIG. 9, the drainage ditch 11A is a culvert-type drainage ditch 11A, and has a slit-shaped opening 16 on the upper surface. Such a culvert-type drainage ditch 11A is also called a slit gutter. The drainage ditch 11A is buried as a culvert-type drainage channel with its upper surface exposed.

[0034] In the forms shown in Figs. 6 to 9, the collector 13 is attached. In the form in which the collector 13 is removed, the catchment basin 12 has a recess 12a deeper than the drainage ditch 11. The recess 12a of the catchment basin 12 has an outlet 12a2 for discharging wastewater to the outside, and a connecting pipe 21 is connected to the outlet 12a2. The catchment basin 12 may be configured to be drained to the outside through the catchment basin 12 and the connecting pipe 21. The catchment basin 12 has an outlet 12a2, and the connecting pipe 21 is connected to the outlet 12a2. This is not a limitation, and the catchment basin 12 may not have the outlet 12a2. The form of the catchment basin 12 to which the drainage ditch 11 is connected is not limited to the form shown in Figs. 6 to 9.

[0035] As shown in FIG. 6, when two drainage ditches 11 are connected at right angles to a square catchment basin 12 that is wider than the width of the U-shape of the drainage ditches 11, the collectors 13e and 13f installed on the two drainage ditches 11 may be arranged so as to be connected in the catchment basin 12. The collectors 13e and 13f may be supported by a support 30 inside the catchment basin 12. In this case, for example, the support 30 may be installed in advance inside the catchment basin 12, and the collectors 13e and 13f may be installed in the two drainage ditches 11, respectively, and slid toward the catchment basin 12 to advance. The collectors 13e and 13f installed on the two drainage ditches 11 may be arranged, for example, in an L-shape in the catchment basin 12. The ends of the collectors 13e and 13f may be adjacent to each other in the catchment basin 12 while placed on the support 30. In this way, even when the lid 14 is attached to the catch basin 12, the two collectors 13e, 13f installed in the drain 11 can be slid toward the catch basin 12 and installed in the catch basin 12. With this configuration, the collectors 13e, 13f can be attached to the catch basin 12. A similar structure can be used in the form shown in Fig. 8.

[0036] A gap may exist between the two collectors 13e and 13f. The ends of the collectors 13e and 13f arranged in the catchment basin 12 may have end walls having a filter function. For example, the ends of the collectors 13e and 13f arranged in the catchment basin 12 may have end walls made of a mesh material. The other ends of the collectors 13e and 13f may be placed on the connection port 12a1 of the drain 11. In the embodiment shown in FIG. 6, a part of the support 30 is placed on the connection port 12a1 of the drain basin 11, and the support 30 may be continuous from the connection port 12a1 of the drain basin 11 to the catchment basin 12.

[0037] 10 and 11 are schematic diagrams showing the structure of the support 30. In the embodiment shown in FIG. 10 and FIG. 11, the capturing structure 10 further includes a support 30 that is attached to the water collecting basin 12 and supports the capturing devices 13e and 13f (see FIG. 6). The support 30 may be installed in the water collecting basin 12 as shown in FIG. 10. In this case, the support 30 may include a base portion 31 and a foot portion 32 that supports the base portion 31. Also, the support 30 may be supported by the lid 14 (grating) of the water collecting basin 12 as shown in FIG. 11. In this case, the support 30 may include a base portion 31 and an arm portion 33 that supports the base portion 31 and is attached to the lid 14. In this way, the support 30 may be suspended from the lid 14 of the water collecting basin 12. In this case, attachment is easy even if the catchment basin 12 is deep, and drainage within the catchment basin 12 is unlikely to be affected. In this case, it is preferable that the arm portion 33 is provided so as not to interfere with the collectors 13e, 13f, and is configured so as not to hinder the operation of the collector 13 when the collectors 13e, 13f are slid from the drain 11 into the catchment basin 12 and installed on the support 30, or when the collectors 13e, 13f are slid toward the drain basin 11 from a state where they are installed on the support 30. The structure of the support 30 and the structures of the collectors 13e, 13f are not limited to those described above.

[0038] Fig. 12 is a plan view showing another embodiment of the collector 13. Fig. 12 shows a configuration in which the collectors 13 installed in the two drainage ditches 11 are slid forward toward the catchment basin 12 and arranged adjacent to each other in the catchment basin 12. An end wall may be provided at the end of the collector 13 that has advanced toward the catchment basin 12. The end wall may be provided with, for example, a net material and have a filtering function. In this configuration, as shown in Fig. 12, the tips 13c of the two collectors 13 may be provided at a predetermined angle and may be configured to butt against each other in the catchment basin 12. In this manner, the collector 13 may be configured to be separable within the catchment basin 12.

[0039] Fig. 13 is a vertical cross-sectional view showing a schematic diagram of a collection structure 10 according to another embodiment. Fig. 13 shows a form in which a culvert-type drain 11A is connected to a catchment basin 12, and a lid 14 (here, a grating) is attached to the catchment basin 12. In this case, the lid 14 is removed from the catchment basin 12 to open it. The collection tool 13 is composed of two collection tools 13g, 13h that are respectively attached to the drain basins 11A (culvert-type) on both sides. The two collection tools 13g, 13h are each configured to have a length that allows them to enter the catchment basin 12 from the opening of the catchment basin 12 from which the lid 14 has been removed. Of the two collectors 13g, 13h, one collector 13g is cylindrical with an inner diameter at one end 13g1 that is wider, and is configured so that one end of the other collector 13h can fit into one end 13g1 of collector 13g.

[0040] For example, when two drainage channels 11A are connected to the catchment basin 12 in a straight line, the collector 13 may be bridged across the connection ports of the two drainage channels 11A in a straight line. In this case, the ends 13g1, 13h1 of the two collectors 13g, 13h extending to the catchment basin 12 may be connected to each other in the catchment basin 12. Also, one end of the collector 13h and one end of the collector 13g may be disposed adjacent to each other in the catchment basin 12. In this case, one end of the collector 13h and one end of the collector 13g may be supported by a support previously installed in the catchment basin 12, although not shown in the drawings. In this case, each end of the collector 13h and one end of the collector 13g may have an end wall. The end wall may have a filter function. In this way, the collection structure 10 preferably includes a catchment basin 12 to which one or more drainage ditches 11 are connected, and a collection device 13 having a bottom wall 131 and side walls 132, 133 (see Figures 4 and 5) with a filter function, and having a shape that allows it to slide along the drainage ditches 11.

As shown in FIG. 14, the collection tool 13 may be configured so that one end is supported by the drain ditch 11 and is installed in a state where it protrudes into the internal space of the water collecting basin. In this case, the collection tool 13 may be attached so that one end of the collection tool 13 extends into the water collecting basin 12 in a state where it is installed in the drain ditch 11. In addition, the one end of the collection tool 13 extending into the water collecting basin 12 may be formed with a wall surface 134 made of a net material. In addition, the one end of the collection tool 13 may be supported by an appropriate support 30 in the water collecting basin 12.

[0042] Furthermore, the collector 13 is not limited to a configuration formed of a semi-cylindrical mesh body with an opening at the top, and may be formed of a cylindrical mesh body. In other words, the collector 13 may further have an upper wall having a filter function. When the collector 13 is formed of a cylindrical mesh body, even when overflow water is discharged, the garbage that has entered the collector 13 can be retained within the collector 13, and the garbage can be prevented from flowing downstream from the catchment basin 12.
