[0014] A road surface forming method and a road surface forming auxiliary member 1 according to a first embodiment of the present invention will be described below with reference to FIGS.

[0015] The road surface molding auxiliary member 1 is placed on a supporting surface (such as crushed stone laid on the ground) when molding a road surface using road surface molding materials such as concrete, mortar, cement, or asphalt, and as shown in Figures 1 to 8, it comprises a plurality of water storage members 2 and a blocking portion 3.

[0016] Resin, biodegradable plastic, etc. may be used as the material for the water storage member 2 and the blocking portion 3. However, when asphalt is used as the road surface molding material, it is preferable to use a heat-resistant material.

[0017] In this embodiment, the water storage member 2 is supported at its sides by three support members 21, as shown in FIGS.

[0018] As shown in Fig. 4 (end view of AA' in Fig. 3), a water storage space S1 is formed inside each water storage member 2. In this embodiment, the water storage member 2 and the three support members 21 are internally connected, and the water storage space S1 is formed by the entire interior of each member.

[0019] At the top of each water storage member 2, a closing portion 3 for closing the water storage space S1 is formed.

[0020] In this embodiment, a substantially T-shaped blocking portion 3 is formed extending from the water storage member 2 toward each support member 21 in a substantially horizontal direction.

[0021] By opening the blocking portion 3, an opening H1 (see FIG. 5) of the water storage space S1 is exposed, the details of which will be described later.

[0022] In addition, each water storage member 2 has a water storage space S1 that is at least partially open on the lower side.

[0023] In this embodiment, as shown in FIGS. 4 and 5, the water storage space S1 is open over the entire bottom surface of the water storage member 2.

[0024] The plurality of water storage members 2 are arranged on a plane, and each water storage member 2 is connected directly or indirectly to an adjacent water storage member 2.

[0025] In this embodiment, as shown in Figures 6 and 7, multiple water storage members 2 extend in an approximately horizontal direction and are connected via wall members 4 that allow multiple water storage members 2 to be connected.

[0026] In addition, in this embodiment, the wall member 4 has an approximately rectangular shape extending horizontally when viewed from the side (a triangular pyramid shape in three dimensions), and its upper end has a height that is approximately the same as or higher than the upper end of the water storage space S1 (in Figure 7, it is approximately the same height as the upper end of the blocking section 3).

[0027] As shown in Figure 1, the water storage member 2 has a plurality of first engagement portions 22 formed thereon, and as shown in Figure 6, the wall member 4 has second engagement portions 41 formed thereon that can engage with the first engagement portions 22.

[0028] In FIG. 1, the first engagement portion 22 is exemplified as a recess formed in the upper portion of each support member 21 facing downward.

[0029] 6 illustrates, as second engagement portions 41, convex portions formed downward from the upper portions of both end portions in the extension direction of wall member 4. Note that FIG. 6(a) is a front view of blocking portion 3, and FIG. 6(b) is a side view of blocking portion 3, but to make second engagement portions 41 easier to understand, FIG. 6(b) is shown on a larger scale than FIG. 6(a).

[0030] As shown in FIG. 7, the support member 21 and the wall member 4 have shapes that allow them to abut against each other with almost no gap when the first engaging portion 22 and the second engaging portion 41 are engaged with each other.

[0031] Furthermore, the wall member 4 is formed with an insertion hole H2 through which the rod-shaped reinforcing member B can be inserted so as to intersect with the extending direction of the wall member 4, the details of which will be described later.

[0032] It is preferable that a plurality of types of wall members 4 having different lengths in the approximately horizontal direction are prepared, and that the first engagement portion 22 is capable of engaging with any of the second engagement portions 41 of the plurality of types of wall members 4. In this embodiment, the second engagement portions 41 of the plurality of types of wall members 4 all have the same shape.

[0033] With this configuration, multiple water storage members 2 are connected via wall members 4, thereby forming individual spaces S2 surrounded by multiple road surface molding auxiliary members 1 (multiple water storage members 2 and multiple wall members 4), as shown in Figure 7, and the road surface is molded by pouring road surface molding material such as concrete onto the road surface molding auxiliary members 1. The method of molding the road surface will be described in detail later.

[0034] 1, in this embodiment, a planar rib 23 is provided extending outward (toward the individual space S2) from the lower end of the water storage member 2 (side wall) to prevent the poured road surface molding material from flowing into the water storage space S1 from the lower end of the water storage member 2. However, the rib 23 is not essential as long as substantially the entire lower end of the water storage member 2 that forms the water storage space S1 is in contact with the placement surface.

[0035] Furthermore, as shown in Figure 7, by combining multiple water storage members 2 and wall members 4, it is possible to arrange multiple insertion holes H2 in a straight line, and rod-shaped reinforcing members B can be inserted into these linearly arranged insertion holes H2. The rod-shaped reinforcing members B work together with the hardened road surface molding material to increase the strength of the entire road surface, and could be, for example, reinforcing bars. Figure 8 shows an example in which rod-shaped reinforcing bars are arranged in a grid pattern.

[0036] In addition, by inserting the rod-shaped reinforcing member B into a plurality of insertion holes H2 arranged in a straight line, the position of the plurality of arranged road surface forming auxiliary members 1 is prevented from shifting due to unevenness, etc.

[0037] Furthermore, the insertion holes H2 also function to form crack prevention joints, the details of which will be described later.

[0038] Next, a road surface forming method using the road surface forming auxiliary member 1 will be described with reference to the flowchart of FIG.

[0039] First, a plurality of water storage members 2 are connected on a placement surface (S1). In this embodiment, the plurality of water storage members 2 are connected via wall members 4. As a result, individual spaces S2 surrounded by the plurality of water storage members 2 and the plurality of wall members 4 are formed.

[0040] Next, rod-shaped reinforcing members B are inserted into the linearly arranged insertion holes H2 (S2). However, steps S1 and S2 may be performed in reverse order or simultaneously. For example, rod-shaped reinforcing members B may be placed on the mounting surface, and then wall members 4 may be placed so that the insertion holes H2 are positioned over the rod-shaped reinforcing members B, and then multiple water storage members 2 may be connected via the wall members 4. Furthermore, if rod-shaped reinforcing members B are not required, step S2 may be omitted.

[0041] Next, the road surface molding material is poured onto the road surface molding auxiliary member 1 up to a height that is approximately the same as or greater than the height of the blocking portion 3 (S3). A height that is approximately the same as or greater than the height of the blocking portion 3 may be a height that covers the blocking portion 3, or may be a height that is approximately flush with the upper end of the blocking portion 3. However, it does not necessarily have to be approximately flush, and may be slightly higher than the upper end of the blocking portion 3.

[0042] Next, after the poured road surface molding material has hardened (S4), the blocking portion 3 and the hardened road surface molding material are polished (S5) until at least the opening H1 of the water storage space S1 is exposed, completing a road surface that allows water to flow into the water storage space S1 from the opening H1, i.e., a road surface with a drainage channel formed (S6). Polishing can be performed using a known concrete polishing machine or the like.

[0043] Note that concrete (ready-mixed concrete) will sink, so when poured to a height approximately flush with the top of the blocking section 3 in S3 of Figure 8, the height of the road surface forming material upon hardening may be slightly lower than the top of the blocking section 3. In this case, the blocking section 3 can be polished first until it is the same height as the hardened road surface forming material after hardening. Furthermore, if the height difference is slight, both the blocking section 3 and the hardened road surface forming material may be polished. In particular, in areas where a strictly smooth road surface is not required, such as parking lots, polishing both the blocking section 3 and the hardened road surface forming material can shorten the work time. Furthermore, if the hardened road surface forming material is slightly higher than the top of the blocking section 3, the raised portion can be polished first.

[0044] In addition, the blocking portion 3 must be made of a material that can be polished together with the hardened road surface molding material, and as mentioned above, it is possible to form it from resin, biodegradable plastic, etc.

[0045] It is preferable that the polishing in S5 be carried out until the wall member 4 is exposed. In this embodiment, the upper end of the wall member 4 has approximately the same height as the upper end of the blocking section 3, so when the blocking section 3 is opened, the wall member 4 is exposed. In other words, the wall member 4 is also polished together, so in this case, the wall member 4 must also be made of a material that can be polished together with the hardened road surface molding material. For example, as mentioned above, it is possible to form the wall member 4 from resin, biodegradable plastic, etc.

[0046] The road surface formed in this way is not monolithic, but is divided into individual spaces S2 as shown in Figure 9, which helps to suppress distortion and cracks.

[0047] In this embodiment, the water storage member 2 has partitions 24 arranged at one or more positions at the bottom of the blocking portion 3 to divide the opening H1 in the horizontal direction, and when the blocking portion 3 is opened by polishing, the partitions 24 are exposed. In this embodiment, the partitions 24 partially connect the upper portions of the opposing side walls of the water storage member 2, thereby forming a grating structure.

[0048] The opening H1 is intended to allow rainwater and the like to flow into the water storage space S1, but the opening H1 is separated at appropriate intervals by one or more partitions 24, thereby preventing large debris and the like from flowing into the water storage space S1.

[0049] Here, concrete (fresh concrete) etc. usually sinks before hardening, so when using a road surface molding auxiliary member that has an opening H1 formed in it from the beginning, it is necessary to pour additional concrete etc. to match the height of the road surface with the height of the upper end of the cylindrical part that forms the opening, which is very laborious and time-consuming, and requires skill.

[0050] However, in the road surface molding method and road surface molding auxiliary member 1 of this embodiment, the road surface molding material is poured onto the road surface molding auxiliary member 1 to a height approximately equal to or higher than the blocking portion 3, and then the blocking portion 3 and hardened road surface molding material are polished until the opening H1 is exposed.This means that there is no need to pour additional concrete or the like to match the height of the road surface with the height of the upper end of the tubular portion that forms the opening, and it is possible to easily mold a flat road surface with a drainage channel (opening H1) formed in it.

[0051] In addition, normally, when polishing the surface of concrete with holes on the surface, it is possible that the opening will be chipped when polishing the area around the opening of the hole. However, in this embodiment, the water storage member 2 that forms the opening H1 is made from resin, biodegradable plastic, etc., so that the opening of opening H1 is prevented from being chipped when polishing.

[0052] As a result of forming the road surface in this manner, surface water flowing into the water storage space S1 through the openings H1 of each road surface forming auxiliary member 1 seeps into the ground below the road surface, preventing environmental problems such as subsidence due to a lack of water underground. Furthermore, because the road surface formed by the road surface forming auxiliary member 1 has a drainage function, it is not necessary to provide a water gradient for drainage on the road surface, making it possible to form a level road surface. Furthermore, because the formed road surface is level, surface water is dispersed into the water storage spaces S1 of each road surface forming auxiliary member 1, allowing the surface water to seep evenly into the ground and preventing surface water from concentrating and draining in a specific area, thereby preventing environmental problems such as river flooding. Furthermore, when there is a large amount of water underground, it is stored in the water storage space S1, automatically adjusting the amount of water underground.

[0053] Furthermore, with the road surface molding method and road surface molding auxiliary member 1 having the above-mentioned configuration, road surface molding material can be poured onto the road surface molding auxiliary member 1 to a height approximately equal to or higher than the blocking portion 3, and then a flat road surface with a drainage channel can be easily molded by simply grinding the blocking portion 3 and the hardened road surface molding material until the opening H1 of the water storage space S1 is exposed, so it can also be used by individuals for DIY road surface molding in parking lots, etc.

[0054] As described above, in the road surface molding method and road surface molding auxiliary member 1 according to this embodiment, road surface molding material is poured onto the road surface molding auxiliary member to a height approximately equal to or greater than the blocking portion 3, and the blocking portion 3 and hardened road surface molding material are polished until at least the opening H1 of the water storage space S1 is exposed.

[0055] With this configuration, it is possible to easily form a flat road surface with a drainage channel (opening H1) by simply grinding the blocking portion 3 and the hardened road surface molding material until the opening H1 of the water storage space S1 is exposed, without having to pour additional concrete or the like to match the height of the road surface with the height of the upper end of the tubular portion that forms the opening.

[0056] In addition, the road surface molding auxiliary member of the present invention corresponding to the manufacturing method of the first embodiment is one in which the opening H1 of the water storage space S1 is formed by grinding the blocking portion 3 formed on the upper part of each water storage member 2 to block the water storage space S1.

[0057] Furthermore, in the road surface forming method and road surface forming auxiliary member 1 according to this embodiment, in the casting step (S3 in FIG. 8), the road surface forming material is cast onto the road surface forming auxiliary member 1 so as to cover the blocking portion 3.

[0058] With this configuration, polishing can be started in a flatter overall state, allowing for smoother polishing.

[0059] In addition, in the road surface forming method and road surface forming auxiliary member 1 of this embodiment, multiple water storage members 2 are indirectly connected via wall members 4 having a height at least approximately the same as the upper end of the water storage space S1, thereby forming individual spaces S2 surrounded by multiple water storage members 2 and multiple wall members 4.

[0060] With this configuration, by polishing the blocking portion 3 and the hardened road surface molding material until the opening H1 and wall member 4 are exposed, it is possible to easily mold a road surface that is divided into individual spaces S2 rather than a monolithic one.

[0061] Furthermore, in the road surface forming method and road surface forming auxiliary member 1 according to this embodiment, the wall member 4 is formed with an insertion hole H2 through which the rod-shaped reinforcing member B can be inserted so as to intersect with the extending direction of the wall member 4.

[0062] This configuration allows rod-shaped reinforcing members B, such as rebar, to be placed in the individual spaces S2, increasing the strength of the road surface when the road surface molding material hardens. Furthermore, by inserting the rod-shaped reinforcing members B into the linearly arranged insertion holes H2, the position of the arranged road surface molding auxiliary members 1 is prevented from shifting due to unevenness or other factors. Furthermore, the road surface molding material placed into the individual spaces S2 also flows into the insertion holes H2 (the spaces surrounding the rod-shaped reinforcing members B), and the road surface molding material placed into adjacent individual spaces S2 bonds with each other via the insertion holes H2. The road surface molding material bonded together via the insertion holes H2 in this way functions as a crack prevention joint, which also helps prevent cracking of the road surface.

[0063] Next, a road surface forming method and a road surface forming auxiliary member 10 according to a second embodiment of the present invention will be described with reference to FIGS.

[0064] In the first embodiment, the road surface molding material was poured onto the road surface molding auxiliary member 1 to a height approximately equal to or higher than the blocking portion 3, but in this embodiment, it is poured to a height approximately equal to or lower than the blocking portion 3.

[0065] In detail, the road surface forming auxiliary member 10 according to this embodiment comprises a water storage member 2 and a blocking portion 3, similar to the road surface forming auxiliary member 1 according to the first embodiment, and the multiple water storage members 2 are arranged on a plane, and each water storage member 2 is directly or indirectly connected to an adjacent water storage member 2. However, in this embodiment, as shown in FIG. 10, it is preferable that the water storage member 2 has an elongated shape (a shape that tapers toward the tip (upper end) in FIG. 10). In FIG. 10, the tip of the elongated water storage member 2 corresponds to the blocking portion 3.

[0066] In Figure 10, a single road surface forming auxiliary member 10 is shown for ease of understanding, but in reality, multiple water storage members 2 are arranged on a plane, and each water storage member 2 is connected directly or indirectly to an adjacent water storage member 2.

[0067] Next, a road surface forming method using the road surface forming auxiliary member 10 will be described with reference to the flowchart of FIG.

[0068] First, a plurality of water storage members 2 are connected on a placement surface (S1).

[0069] Next, rod-shaped reinforcing members B are inserted into the linearly arranged insertion holes H2 (S2). However, steps S1 and S2 may be performed in reverse order or simultaneously. For example, rod-shaped reinforcing members B may be placed on the mounting surface, and then wall members 4 may be placed so that the insertion holes H2 are positioned over the rod-shaped reinforcing members B, and then multiple water storage members 2 may be connected via the wall members 4. Furthermore, if rod-shaped reinforcing members B are not required, step S2 may be omitted.

[0070] Next, the road surface molding material is poured onto the road surface molding auxiliary member 1 up to a height that is approximately equal to or less than the height of the blocking portion 3 (S3). A height that is approximately equal to or less than the height of the blocking portion 3 may be a height that is approximately flush with the upper end of the blocking portion 3, or a height that is lower than that. However, as shown in Figure 10, it is necessary to pour in an amount of road surface molding material such that when the poured-in road surface molding material hardens, the hardened road surface formation material C will be located below the lower end of the blocking portion 3.

[0071] Next, after the poured road surface forming material has hardened (S4), as shown in Figure 10, the portions D of the blocking portion 3 and the water storage member 2 that protrude above the hardened road surface forming material C are cut away to expose the opening H1 of the water storage space S1 (S5). The protruding portions D can be cut away by cutting them off using a blade such as a saw. Also, if the protruding portions D are small, they may be cut away by scraping them off.

[0072] Furthermore, since concrete (ready-mixed concrete) etc. will sink, even if the road surface forming material is poured up to a height that is approximately flush with the upper end of the blocking section 3, the road surface forming method of this embodiment can be used as long as the hardened road surface forming material C is located below the lower end of the blocking section 3.

[0073] Finally, the upper part of the water storage member 2 remaining after cutting and the hardened road surface molding material are polished to the desired height (S6), completing a road surface that allows water to flow into the water storage space S1 from the opening H1, i.e., a road surface with a drainage channel formed (S7).

[0074] As described above, in the road surface forming method and road surface forming auxiliary member 10 according to this embodiment, road surface forming material is poured onto the road surface forming auxiliary member up to a height approximately equal to or less than the blocking portion 3, and the blocking portion 3 and the portion D of the water storage member 2 that protrudes above the hardened road surface forming material C are cut off, and then the upper portion of the water storage member 2 and the hardened road surface forming material remaining after cutting are polished to the desired height.

[0075] According to this configuration, in addition to the effects of the first embodiment, it is possible to save concrete and reduce the amount of polishing work because it is only necessary to pour concrete to a height close to the desired height. Furthermore, since the thin water storage member 2 is easy to cut, it is particularly effective when forming a flat road surface with a thin drainage channel (opening H1) formed therein.

[0076] In addition, the road surface molding auxiliary member of the present invention corresponding to the manufacturing method of the second embodiment is one in which the opening H1 is formed by cutting off the blocking portion 3 formed on the top of each water storage member 2 to block the water storage space S1, and then grinding off the top of the water storage member 2 remaining after cutting.

[0077] Next, a road surface forming method and a road surface forming auxiliary member 20 according to a third embodiment of the present invention will be described with reference to FIGS.

[0078] In the second embodiment, the road surface forming auxiliary member 10 was provided with a blocking portion 3, but the road surface forming auxiliary member 20 of this embodiment does not have a blocking portion 3, and the upper side of the water storage space S1 is exposed from the beginning.

[0079] In detail, the road surface forming auxiliary member 20 according to this embodiment is equipped with a water storage member 2, similar to the road surface forming auxiliary member 10 according to the second embodiment, and the multiple water storage members 2 are arranged on a plane, with each water storage member 2 being directly or indirectly connected to an adjacent water storage member 2. However, in this embodiment, as shown in Figure 12, the upper side of the water storage member 2 is exposed from the start. In this case too, it is preferable that it has an elongated shape (a shape that tapers towards the tip (upper end) in Figure 12).

[0080] Next, as in the second embodiment, a road surface forming method using the road surface forming auxiliary member 20 will be described using the flowchart in FIG.

[0081] First, a plurality of water storage members 2 are connected on a placement surface (S1).

[0082] Next, rod-shaped reinforcing members B are inserted into the linearly arranged insertion holes H2 (S2). However, steps S1 and S2 may be performed in reverse order or simultaneously. For example, rod-shaped reinforcing members B may be placed on the mounting surface, and then wall members 4 may be placed so that the insertion holes H2 are positioned over the rod-shaped reinforcing members B, and then multiple water storage members 2 may be connected via the wall members 4. Furthermore, if rod-shaped reinforcing members B are not required, step S2 may be omitted.

[0083] Next, the road surface molding material is poured onto the road surface molding auxiliary member 1 up to a height that is approximately equal to or less than the upper end of the water storage member 2 (S3). The height that is approximately equal to or less than the upper end of the water storage member 2 may be a height that is approximately flush with the upper end of the water storage member 2, or may be a height that is lower than that.

[0084] Next, after the poured road surface forming material has hardened (S4), as shown in Figure 12, the portion D of the water storage member 2 that protrudes above the hardened road surface forming material C is cut away to expose the opening H1 of the water storage space S1 (S5). The protruding portion D can be cut away by cutting it off using a blade such as a saw. Also, if the protruding portion D is small, it may be cut away by scraping it off.

[0085] Furthermore, since concrete (ready-mixed concrete) and the like will sink, even if the road surface forming material is poured up to a height that is approximately flush with the upper end of the water storage member 2, the road surface forming method of this embodiment can be used as long as the hardened road surface forming material C is located below the upper end of the water storage member 2.

[0086] Finally, the upper part of the water storage member 2 remaining after cutting and the hardened road surface molding material are polished to the desired height (S6), completing a road surface that allows water to flow into the water storage space S1 from the opening H1, i.e., a road surface with a drainage channel formed (S7).

[0087] As described above, in the road surface forming method and road surface forming auxiliary member 20 according to this embodiment, road surface forming material is poured onto the road surface forming auxiliary member up to a height approximately equal to or less than that of the water storage member 2, and the portion of the water storage member 2 that protrudes above the hardened road surface forming material is cut off, and then the upper portion of the water storage member 2 and the hardened road surface forming material remaining after cutting are polished to the desired height.

[0088] According to this configuration, in addition to the effects of the first embodiment, it is only necessary to pour concrete up to a height close to the desired height, which makes it possible to save concrete and reduce the amount of work required for polishing. Also, since the thin water storage member 2 can be easily cut, such as by cutting, this is particularly effective when forming a flat road surface with a thin drainage channel (opening H1) formed therein.

[0089] In addition, the road surface molding auxiliary member of the present invention corresponding to the manufacturing method of the third embodiment is one in which the opening H1 is formed by cutting the upper part of each water storage member 2 and then polishing the upper part of the water storage member 2 remaining after cutting.

[0090] The road surface forming method and road surface forming auxiliary member of the present invention are not limited to the above-described embodiment, and various modifications and improvements are possible within the scope of the claims.

[0091] For example, in the above embodiment, the water storage member 2 is supported by three support members 21, but the support members 21 are not essential. Also, for example, as shown in Figure 13, the shape of the water storage member 2 may of course be different from that described in the above embodiment ((a) is a side view, (b) is a plan view).

[0092] Furthermore, in the above embodiment, the plurality of water storage members 2 are indirectly connected via the wall members 4, but the water storage members 2 may be directly connected to each other.

[0093] Furthermore, in the above embodiment, the multiple water storage members 2 are separate bodies, but they may also be formed as an integrated unit as shown in Figure 13. However, even in this case, it is preferable that the road surface molding auxiliary member 1 made up of multiple water storage members 2 be connectable to other road surface molding auxiliary members 1.

[0094] Furthermore, in the above embodiment, polishing was stopped when the opening H1 was exposed (at the height of the upper end of the water storage space S1), which allowed the entire road surface to be molded to a substantially flat height, but there may be cases where it is desired to make the road surface lower than the upper end of the water storage space S1. In this case, polishing can be carried out to a position lower than the upper end of the water storage space S1, but since there is no guideline such as "polishing until the opening H1 is exposed," there is a possibility that the height of the molded road surface will vary.

[0095] Therefore, as shown in Fig. 14, it is conceivable to provide one or more marker portions 25 indicating the polishing end position at one or more predetermined height positions on the water storage member 2. As the marker portion 25, for example, it is conceivable to provide a change in color or a step (including a protrusion or depression). Fig. 14 shows an example in which a plurality of marker portions 25 that can be distinguished according to height are provided.

[0096] With this configuration, by ending polishing using the exposed mark portion 25 as a guide, it is possible to form a road surface of a desired height without any variation in height.

[0097] If polishing is to be performed to a position lower than the stage where the opening H1 is exposed (the height of the upper end of the water storage space S1), at least the upper part of the water storage member 2 must be made of a material that can be polished together with the hardened road surface molding material. For example, as mentioned above, it is possible to form it from resin, biodegradable plastic, etc.

[0098] 15, one or more marker portions 42 indicating the polishing end position may be provided at one or more predetermined height positions on the wall member 4, instead of the water storage member 2. Alternatively, the water storage member 2 and the wall member 4 may each be provided with the marker portion 25 and the marker portion 42.

[0099] Furthermore, in the above embodiment, the wall member 4 was polished together with the hardened road surface molding material, but by setting the height of the wall member 4 to a desired height below the upper end of the water storage space S1, it is also possible to use the upper end of the wall member 4 as the marker 42. In this case, polishing ends when the wall member 4 is exposed, so the wall member 4 does not need to be made of a material that can be polished together with the hardened road surface molding material.

[0100] Furthermore, the polishing machine may be configured to be able to grasp the polishing end position.

[0101] In this case, for example, a grinding machine capable of detecting metal located within a predetermined distance L below the surface to be ground is used. As shown in Figure 16, at least the upper side of the water storage member 2 is formed of a material other than metal (resin, biodegradable plastic, etc.) that can be ground together with the hardened road surface molding material, and a configuration is conceivable in which metal M is placed in the water storage member 2 at a position lower than the predetermined distance L from the upper end of the water storage space S1. For example, if metal M is placed at a position slightly lower than the predetermined distance L, the metal will be detected as soon as opening H1 is exposed.

[0102] The metal may be embedded in the resin or attached to the resin. To detect the metal, a known mechanism such as a metal detector may be used.

[0103] With this configuration, the metal is detected when polishing has been performed up to a position a predetermined distance from the metal, so that the polishing end position can be easily determined.

[0104] Similarly, a configuration in which metal is placed on the wall member 4 side is also conceivable. In this case, at least the upper side of the wall member 4 is formed of a material other than metal (resin, biodegradable plastic, etc.) that can be polished together with the hardened road surface molding material, and the metal M is placed on the wall member 4 at a position lower than a predetermined distance L from the upper end of the water storage space S1 of the water storage member 2.

[0105] The metal M may be disposed on both the water storage member 2 and the wall member 4, or on either one of them. In addition, in FIG. 16, the metal M extends horizontally over the entire water storage member 2 and the wall member 4, but it may also be disposed partially in the horizontal direction.

[0106] Furthermore, in the above embodiment, the road surface forming auxiliary member 1 was placed on crushed stone laid on the ground, but it may also be placed directly on the ground, in which case the ground would correspond to the "placing surface."

[0107] Furthermore, in the above embodiment, resin, biodegradable plastic, etc. are used as materials for the water storage member 2, the blocking portion 3, and the wall member 4, but other materials may be used as long as they can be polished. [Explanation of symbols]
