Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the above technique, it is necessary to form a hole that penetrates the protective wall and extends to the bedrock located on the back side of the ground by a boring machine, which requires a great deal of labor. In addition, the attachment strength of the anchor pile also changes depending on the strength of the ground and the bedrock.

[0005] Therefore, an object of the present invention is to provide an anchor pile that can be easily and stably attached to a road surface or the like and a method for attaching the anchor pile.

Means for Solving the Problems

[0006] The present invention relates to an anchor pile for fixing a structure to be placed on a road surface formed by a road surface forming auxiliary member, wherein the road surface forming auxiliary member has a water storage member with a water storage space formed inside, and at least one substantially horizontal opening is formed or can be formed at the upper part of the water storage member and communicates with the water storage space, and a plurality of the road surface forming auxiliary members are arranged on a mounting surface and connected directly or indirectly to form individual spaces surrounded by the plurality of road surface forming auxiliary members, and as the road surface forming material driven into the individual spaces hardens, a road surface is formed that allows water to flow from the opening into the water storage space, The anchor pile is characterized in that it comprises an anchor portion having a laterally extending extension and insertable into the water storage space from the opening, a pile portion extending upward from the anchor portion, and a fixing portion attached to the pile portion, wherein a locking portion is provided inside the water storage member forming the water storage space, which can lock the extension of the anchor portion that has been rotated to a substantially horizontal direction within the water storage space in order to restrict the upward movement of the pile portion, and the fixing portion is attached to the pile portion at a position that directly or indirectly abuts the road surface shaping auxiliary member from above in order to restrict the downward movement of the pile portion.

[0007] With this configuration, by utilizing the fact that openings used for drainage and water storage are formed in the road surface molding auxiliary member, it becomes possible to easily and stably attach anchor piles to the road surface molding auxiliary member.

[0008] Furthermore, according to another aspect of the present invention, a method for attaching the above-mentioned anchor piles is provided. [Effects of the Invention]

Embodiments for Carrying Out the Invention

[0011] Hereinafter, the anchor pile 10 according to the embodiment of the present invention will be described with reference to FIGS. 1 to 13.

[0012] Since the anchor pile 10 is for fixing a structure provided on a road surface formed by the road surface forming auxiliary member 1, first, the road surface forming auxiliary member 1 will be described.

[0013] The road surface forming auxiliary member 1 is arranged on a placement surface (crushed stones or the like laid on the ground) during the formation of a road surface with a road surface forming material such as concrete, mortar, cement, or asphalt. As shown in FIGS. 1 to 7, it includes a water storage member 2 and a wall member 3.

[0014] As materials for the water storage member 2 and the wall member 3, resins, biodegradable plastics, etc. can be considered. However, when asphalt is used as the road surface forming material, it is preferable to use a heat-resistant material.

[0015] In the present embodiment, as shown in FIGS. 1 to 5, the side portion of the water storage member 2 is supported by three support members 21.

[0016] As shown in FIG. 4, a water storage space S1 is formed inside the water storage member 2. In the present embodiment, the water storage member 2 and the three support members 21 communicate with each other inside, and the entire interior of each member forms the water storage space S1. Note that FIG. 4 is a sectional view of the end face A - A' of FIG. 3, but for easy understanding, the upper cross-section of the water storage member 2 is also shown by a solid line.

[0017] An opening H1 that communicates with the water storage space S1 and extends in at least one substantially horizontal direction X is formed or can be formed at the upper part of the water storage member 2.

[0018] In this embodiment, as shown in Figure 3, the upper part of the water storage member 2 is cut out in a roughly T-shape, thereby pre-forming a roughly T-shaped opening H1 that extends roughly horizontally from the water storage member 2 towards each support member 21. In this case, one or both of the two straight lines forming the T-shape correspond to "one opening H1 extending roughly horizontally in direction X".

[0019] Furthermore, the opening H1 is partitioned by partition portions 22 positioned at one or more locations in its extending direction. In this embodiment, the partition portions 22 partially connect the upper parts of opposing side walls of the water storage member 2, thereby forming a grating structure.

[0020] The opening H1 is designed to allow surface water to flow into the water storage space S1, but the opening H1 is partitioned by one or more partitions 22 at appropriate intervals, thereby preventing large debris from flowing into the water storage space S1.

[0021] Furthermore, a first groove 23 is formed at the upper end of the water storage member 2, along the opening H1 that extends toward each support member 21.

[0022] A lid member 4 is provided or can be attached to the upper part of the water storage member 2 to close the opening H1.

[0023] In this embodiment, the opening H1 is closed by attaching a cover member 4 to the first groove 23. As shown in Figure 1, the cover member 4 can be a long piece of resin or the like with a width that fits just into the first groove 23. In this embodiment, a cylindrical cover member 4 such as a rubber hose is used so as to be able to accommodate slight changes in the width of the first groove 23.

[0024] At least partially, the water storage space S1 is open on the lower side of the water storage member 2.

[0025] In this embodiment, as shown in Figures 4 and 5, the water storage space S1 is open across the entire bottom surface of the water storage member 2.

[0026] Furthermore, the water storage member 2 has a plurality of first engaging portions 24 formed thereon.

[0027] In this embodiment, as shown in Figures 1 and 3, a downward-facing recess is formed on the upper part of each support member 21 as the first engaging portion 24.

[0028] The wall member 3 extends in a substantially horizontal direction and is capable of connecting multiple water storage members 2.

[0029] In this embodiment, as shown in Figure 6, the wall member 3 has a roughly rectangular shape extending horizontally in a side view (a truncated triangular pyramid shape in three dimensions) and has approximately the same height as the water storage member 2. Note that the condition "the water storage member 2 and the wall member 3 have approximately the same height" also applies when multiple members are connected vertically to achieve the same height.

[0030] The wall member 3 has a second engaging portion 31 that can engage with the first engaging portion 24.

[0031] Furthermore, in this embodiment, the protrusions extending downward from the upper part of both ends in the extending direction of the wall member 3 are formed as second engaging portions 31. Figure 6(a) is a front view of the wall member 3, and Figure 6(b) is a side view of the wall member 3. To facilitate understanding of the second engaging portions 31, Figure 6(b) is shown at a larger scale than Figure 6(a).

[0032] Furthermore, as shown in Figure 7, the support member 21 and the wall member 3 have a shape such that they come into contact with virtually no gap when the first engaging portion 24 and the second engaging portion 31 are engaged.

[0033] At the upper end of the wall member 3, a second groove 32 is formed, which is continuous with the first groove 23 and to which the lid member 4 can be attached. In this embodiment, the second groove 32 has approximately the same height and width as the first groove 23. Because the first groove 23 and the second groove 32 are continuous, it is possible to attach the lid member 4 all at once so as to span from the first groove 23 to the second groove 32.

[0034] Furthermore, the wall member 3 has an insertion hole H2 through which a rod-shaped reinforcing member B can be inserted, intersecting its extension direction; the details of this will be described later.

[0035] As wall members 3, it is preferable to prepare multiple types of wall members 3 with substantially different horizontal lengths in order to be able to mold road surfaces of various sizes, and that the first engaging portion 24 can engage with any of the second engaging portions 31 of the multiple types of wall members 3. In this embodiment, it is assumed that the second engaging portions 31 of the multiple types of wall members 3 all have the same shape.

[0036] Under this configuration, multiple road surface shaping auxiliary members 1 are arranged on the mounting surface and connected directly or indirectly (in this embodiment, multiple water storage members 2 are connected via wall members 3), as shown in Figure 7, individual spaces S2 surrounded by multiple road surface shaping auxiliary members 1 (multiple water storage members 2 and multiple wall members 3) are formed. When the road surface shaping material such as concrete poured into the individual spaces S2 hardens, a road surface with drainage function is formed that allows water to flow into the water storage space S1 from the opening H1. Details of the road surface shaping method will be described later.

[0037] In this embodiment, as shown in Figure 1, a planar rib 25 is provided extending outward (towards 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 25 is not essential if substantially the entire lower end of the water storage member 2 forming the water storage space S1 is in contact with the mounting surface.

[0038] Furthermore, as shown in Figure 7, by combining multiple water storage members 2 and wall members 3, it is possible to arrange multiple insertion holes H2 in a linear fashion, and the rod-shaped reinforcing member B can be inserted into these linearly arranged multiple insertion holes H2. The rod-shaped reinforcing member B is intended to work in cooperation with the hardened road surface molding material to increase the overall strength of the road surface, and could be, for example, reinforcing bars. Figure 7 shows an example in which rod-shaped reinforcing bars are arranged in a grid pattern.

[0039] Furthermore, by inserting the rod-shaped reinforcing member B into multiple insertion holes H2 arranged in a straight line, the position of the multiple road surface shaping auxiliary members 1 arranged therein is also suppressed from shifting due to the effects of unevenness, etc.

[0040] Furthermore, the through-hole H2 also functions to form crack-preventing joints, but the details of this will be described later.

[0041] Next, we will explain the road surface molding method using the road surface molding auxiliary member 1 with reference to the flowchart in Figure 8.

[0042] First, multiple water storage members 2 are connected on the mounting surface via wall members 3 (S1). This creates individual spaces S2 surrounded by multiple water storage members 2 and multiple wall members 3.

[0043] Next, the rod-shaped reinforcing members B are inserted through multiple insertion holes H2 arranged in a straight line (S2). However, S1 and S2 may be performed in reverse order or simultaneously. For example, the rod-shaped reinforcing members B may be placed on the mounting surface, and the wall members 3 may be positioned so that the insertion holes H2 are located on the rod-shaped reinforcing members B, after which the multiple water storage members 2 may be connected via the wall members 3. Also, if the rod-shaped reinforcing members B are not required, step S2 may be omitted.

[0044] Next, the lid member 4 is attached to the first groove 23 of the water storage member 2 and the second groove 32 of the wall member 3 (S3).

[0045] Next, the road surface molding material is poured into the individual space S2 (S4). Specifically, the road surface molding material is poured up to a height near the top of the water storage member 2. At this time, since the opening H1 is closed by the lid member 4, it is prevented that the road surface molding material will flow into the water storage space S1 from the opening H1. If the road surface molding material can be poured in a way that prevents it from flowing into the opening H1, the step in S3 may be omitted.

[0046] Finally, by opening the cover member 4 after the road surface molding material has hardened (S5), a road surface is completed in which water can flow from the opening H1 into the water storage space S1, i.e., a road surface with a drainage channel formed (S6). The cover member 4 may be opened when the road surface molding material has completely hardened, or when the road surface molding material has hardened to the extent that it does not flow into the water storage space S1 from the opening H1. Also, if step S3 is omitted, a road surface with a drainage channel formed will be completed when the road surface molding material has hardened.

[0047] The road surface formed in this way is not a single, monolithic structure, but rather divided into individual spaces S2, as shown in Figure 9, thus suppressing strain and cracking.

[0048] Furthermore, the road surface molding material poured into individual spaces S2 also flows into the through holes H2 (the space surrounding the rod-shaped reinforcing member B), so the road surface molding material poured into adjacent individual spaces S2 will bond to each other via the through holes H2. In this case, the portion of the hardened road surface molding material that hardens within the through holes H2 functions as a crack-preventing joint and is more prone to cracking than other parts, thus also suppressing cracking of the road surface.

[0049] As a result of the road surface being formed in this manner, surface water that flows into the water storage space S1 from the opening H1 of each road surface forming auxiliary member 1 seeps into the ground below the road surface, suppressing environmental problems such as ground subsidence due to insufficient groundwater. Furthermore, since the road surface formed by the road surface forming auxiliary member 1 has a drainage function, there is no need to provide a water slope on the road surface for drainage, making it possible to form a horizontal road surface. And because the formed road surface is horizontal, the surface water is distributed into the water storage space S1 of each road surface forming auxiliary member 1, so that the surface water seeps into the ground evenly, and it is prevented from being drained in a predetermined place, and as a result, environmental problems such as river flooding are suppressed. In addition, if the amount of water in the ground is large, it is stored in the water storage space S1, so the amount of water in the ground is automatically regulated.

[0050] Furthermore, with the above-described road surface shaping auxiliary member 1 and road surface shaping method, a crack-resistant road surface with drainage function can be formed simply by combining multiple road surface shaping auxiliary members 1 and driving in road surface shaping material. Therefore, it is possible for individuals to use it for DIY road surface shaping in parking lots, etc. In this case, by using wall members 3 of a size (horizontal length) that corresponds to the size of the road surface to be shaped and the space in which the road surface will be shaped, it becomes possible to shape the road surface with a high degree of freedom.

[0051] Next, I will explain the anchor pile 10.

[0052] The anchor pile 10 is for fixing structures (garages, warehouses, fences, etc.) that are installed on the road surface formed by the road surface forming auxiliary member 1, and as shown in Figure 10, it comprises an anchor part 11, a pile part 12, a fixing part 13, and a rotation restricting part 14. Figures 10(a) and 10(b) are views of the anchor pile 10 from the front and side, respectively.

[0053] The anchor portion 11 has a laterally extending portion 11a and can be inserted into the water storage space S1 through the opening H1.

[0054] In this embodiment, the anchor portion 11 has a triangular shape with the top as the vertex or a trapezoidal shape with the top as the base, and both hypotenuses (legs) constitute a pair of extension portions 11a. The length of the base of the anchor portion 11 (the length between the pair of extension portions 11a) is longer than the width of the opening H1, and the width of the anchor portion 11 is shorter than the width of the opening H1. Therefore, when inserting the anchor portion 11 into the water storage space S1 from the opening H1, as shown in Figure 11(a), the pair of extension portions 11a are inserted in a direction that is substantially parallel to a substantially horizontal direction X.

[0055] Furthermore, in this embodiment, since the opening H1 is partitioned by a partition 22 as shown in Figure 3, the length of the base of the anchor portion 11 (the length between the pair of extensions 11a) is designed to be shorter than the length between adjacent partitions 22 in order to allow the anchor portion 11 to be inserted through the opening H1. An anchor portion 11 having such a configuration can be inserted, for example, through the opening H1 of the mounting portion F in Figure 3.

[0056] In this embodiment, as shown in Figure 11 (a schematic cross-sectional view of the area near the mounting portion F in Figure 3), a locking portion 28 is provided inside the water storage member 2 that forms the water storage space S1, which can lock the extended portion 11a of the anchor portion 11 that has been rotated to another substantially horizontal direction Y within the water storage space S1, in order to restrict the upward movement of the pile portion 12.

[0057] In this embodiment, since the other substantially horizontal direction Y is a direction substantially perpendicular to one substantially horizontal direction X, a pair of locking portions 28 are provided on at least one pair of inner wall surfaces 27 in a direction substantially perpendicular to one substantially horizontal direction X.

[0058] In particular, in this embodiment, the water storage member 2 has a pair of substantially flat members facing each other in at least another substantially horizontal direction Y to form a water storage space S1. The pair of substantially flat members are arranged so that they move away downward when viewed from a substantially horizontal direction perpendicular to the other substantially horizontal direction Y (in this embodiment, one substantially horizontal direction X), so that the inner wall surfaces 27 of each of the pair of substantially flat members constitute a locking portion 28. The anchor portion 11, which is rotated in the other substantially horizontal direction Y, has a shape that at least partially follows the inner wall surface 27 when viewed from a substantially horizontal direction perpendicular to the other substantially horizontal direction Y (in this embodiment, one substantially horizontal direction X) (in Figure 11(b), it is a triangular shape with the top as the apex or a trapezoidal shape with the top as the base), thus constituting an extension portion 11a. In other words, the structure in which the pair of substantially flat members are arranged so that they move away downward in order to ensure the stability of the water storage member 2 on the mounting surface is used to restrict the upward movement of the pile portion 12 (anchor portion 11).

[0059] The pile portion 12 extends upward from the anchor portion 11. In this embodiment, the pile portion 12 is assumed to have threads along its extension direction.

[0060] The fixing part 13 is attached to the pile part 12. More specifically, the fixing part 13 is attached to the pile part 12 at a position where it directly or indirectly contacts the road surface shaping auxiliary member 1 from above in order to restrict the downward movement of the pile part 12. In this embodiment, the fixing part 13 has a nut shape that screws onto a thread cut into the pile part 12.

[0061] As shown in Figure 10, the rotation restricting portion 14 comprises a base portion 14a and a pair of protrusions 14b.

[0062] As shown in Figure 12(a) (top view of the rotation restricting portion 14), the base portion 14a has an insertion portion 14c through which the pile portion 12 can be inserted, and as shown in Figures 12(b) and 12(c), it is positioned between the opening H1 and the fixing portion 13. In this embodiment, the base portion 14a has a disc shape with a size that prevents it from passing through the opening H1. A through hole is formed in the insertion portion 14c.

[0063] The pair of protrusions 14b project downward from the base 14a and are positioned within the opening H1, as shown in Figure 12(b). The anchor portion 11 is positioned at least partially between the pair of protrusions 14b, with its extension 11b locked to the locking portion 28, as shown in Figure 12(c).

[0064] Furthermore, in order to position the anchor portion 11 between the pair of protrusions 14b, the width of the anchor portion 11 must be narrower than the width between the pair of protrusions 14b. However, since the rotation of the anchor portion 11 is restricted by the pair of protrusions 14b, if the width of the anchor portion 11 is too narrow (if the width between the pair of protrusions 14b is too wide), its function will be reduced. Therefore, in this embodiment, the width of the anchor portion 11 is set to be slightly narrower than the distance between the pair of protrusions 14b.

[0065] Furthermore, in order for the pair of protrusions 14b to restrict the rotation of the anchor portion 11, the pair of protrusions 14b themselves must not rotate. Therefore, as shown in Figure 12(b) (a view of the protrusions 14b and the opening H1 from below), the width of the protrusions 14b in the other substantially horizontal direction Y is set to be only slightly narrower than the width of the opening H1. However, if the distance between the pair of protrusions 14b is narrower than the width of the opening H1, it is prevented that the pair of protrusions 14b will rotate completely.

[0066] Next, the method for attaching the anchor pile 10 to the road surface (road surface shaping auxiliary member 1) will be explained using the flowchart in Figure 13.

[0067] First, the anchor portion 11 is inserted into the water storage space S1 through the opening H1 (S11).

[0068] Next, the pair of protrusions 14b of the rotation restricting part 14 are positioned inside the opening H1 (S12). At this stage, the pile portion 12 is inserted through the insertion portion 14c of the rotation restricting part 14, but the insertion of the pile portion 12 into the insertion portion 14c may be performed in either S11 or S12. Also, if the anchor pile 10 does not have a rotation restricting part 14, S12 is omitted.

[0069] Next, the anchor portion 11 is rotated in another substantially horizontal direction Y (S13). In this embodiment, the anchor portion 11 is rotated by rotating the pile portion 12. Also in this embodiment, the other substantially horizontal direction Y is a direction that is substantially perpendicular to the first substantially horizontal direction X.

[0070] Next, the extended portion 11a is locked to the locking portion 28 of the inner wall surface 27 (S14).

[0071] In this embodiment, as shown in Figure 11(b), pulling the pile portion 12 upward causes the pair of extensions 11a to be locked to the pair of locking portions 28, thereby restricting the upward movement of the pile portion 12. At the same time, pulling the pile portion 12 upward also causes the anchor portion 11 to be positioned between the pair of protrusions 14b.

[0072] Finally, in order to restrict the downward movement of the pile portion 12, the fixing portion 13 is attached to the pile portion 12 at a position where it directly or indirectly contacts the road surface shaping auxiliary member 1 from above (S15).

[0073] In this embodiment, the pile portion 12 is fixed to the road surface shaping auxiliary member 1 by rotating the nut-shaped fixing portion 13, which is screwed onto the pile portion 12, until the area near the opening H1 of the road surface shaping auxiliary member 1 is firmly clamped between the fixing portion 13 and the extension portion 11b. As a result, structures (garages, warehouses, fences, etc.) to be installed on the road surface shaped by the road surface shaping auxiliary member 1 can be stably fixed to the pile portion 12.

[0074] Furthermore, in this embodiment, since the anchor portion 11 is positioned between a pair of protrusions 14b whose rotation is restricted by the opening H1, the rotation of the anchor portion 11 is also restricted by the pair of protrusions 14b. This prevents the anchor portion 11 from rotating unintentionally and the locking portion 28 from disengaging from the extension portion 11b.

[0075] As described above, in the anchor pile 10 and the method of attaching the anchor pile 10 according to this embodiment, a locking portion 28 is provided inside the water storage member 2 that forms the water storage space S1, which can lock the extended portion 11a of the anchor portion 11 that has been rotated to another substantially horizontal direction Y within the water storage space S1 in order to restrict the upward movement of the pile portion 12.

[0076] With this configuration, by utilizing the fact that the opening H1 used for drainage and water storage is formed in the road surface shaping auxiliary member 1, it becomes possible to easily and stably attach the anchor pile 10 to the road surface shaping auxiliary member 1.

[0077] Furthermore, in the anchor pile 10 and the method of attaching the anchor pile 10 according to this embodiment, the water storage member 2 has a pair of substantially flat plate-shaped members that face each other in at least another substantially horizontal direction Y in order to form a water storage space S1, and the pair of substantially flat plate-shaped members are arranged so that they move away from each other downward when viewed from a substantially horizontal direction perpendicular to the other substantially horizontal direction Y, so that the inner wall surfaces 27 of each of the pair of substantially flat plate-shaped members constitute a locking portion 28, and the anchor portion 11 rotated in the other substantially horizontal direction Y has a shape that at least partially follows the inner wall surface 27 when viewed from a substantially horizontal direction perpendicular to the other substantially horizontal direction Y, thereby constituting an extension portion 11a.

[0078] With this configuration, by utilizing a structure in which a pair of substantially flat plate-shaped members are arranged to move away from each other downwards in order to ensure the stability of the water storage member 2 on the mounting surface, it becomes possible to easily restrict the upward movement of the pile portion 12 (anchor portion 11).

[0079] Furthermore, in the anchor pile 10 and the method of attaching the anchor pile 10 according to this embodiment, the anchor portion 11 is positioned at least partially between a pair of protruding portions 14b with the extension portion 11b locked to the locking portion 28.

[0080] This configuration prevents the anchor portion 11 from rotating unintentionally and the locking portion 28 from disengaging from the extension portion 11b.

[0081] Furthermore, the anchor pile and anchor pile installation method of the present invention are not limited to the embodiments described above, and various modifications and improvements are possible within the scope of the claims.

[0082] For example, although the above embodiment includes a rotation restricting portion 14, this does not exclude the possibility of fixing the opening H1 only with the fixing portion 13 on the upper side. In this case, it is preferable that the fixing portion 13 has a shape that prevents it from passing through the opening H1.

[0083] Furthermore, in the above embodiment, the lid member 4 was configured to be attachable to the upper part of the water storage member 2, but the lid member 4 may also be provided on the upper part of the water storage member 2. In this case, the lid member 4 may be configured to be openable, or the opening H1 may be formed by destroying the lid member 4. When destroying the lid member 4, it is possible to create a cut, dotted line, or step in the connection part between the lid member 4 and the upper part of the water storage member 2, and then open the lid member 4 by hitting and breaking it with a hammer. Alternatively, the opening H1 may be formed by polishing the lid member 4. In this case, depending on the position of the lid member 4 relative to the water storage member 2 and the height of the hardened road surface molding material, the lid member 4 may also be polished together with the upper part of the water storage member 2 and the hardened road surface molding material.

[0084] Furthermore, in the above embodiment, the wall member 3 extended in a straight line, but in order to increase the degree of freedom in road surface molding, it is also possible to have a configuration in which the direction of extension changes midway, as shown in Figure 14(a) (both viewed from above), or a configuration in which it branches in multiple directions, with a second engaging portion 31 formed at each branch point, as shown in Figure 14(b). In the case of a configuration that extends in multiple directions, it becomes possible to mold road surfaces with polygonal shapes other than rectangular shapes. For example, as shown in Figure 14(c), by branching the wall member 3 in a Y shape, it becomes possible to mold a hexagonal road surface. Furthermore, as shown in Figure 14(d), multiple wall members 3 may be configured to be connectable, further increasing the degree of freedom in road surface molding. In this case, the wall members 3 may be connected to each other by making the second engaging portions 31 formed on each of them engageable with each other, or the wall members 3 may be connected to each other by separately providing other engaging portions and making the other engaging portions engageable with each other.

[0085] Furthermore, in the above embodiment, a rectangular individual space S2 is formed by connecting three wall members 3 to a T-shaped water storage member 2, as shown in Figure 7. However, the shape of the water storage member 2 is not limited to a T-shape, nor is the number of connected wall members 3 limited to three. For example, as shown in Figure 15, four wall members 3 can be connected to a water storage member 2 that extends in a cross shape. In this case, four first engaging portions 24 are formed on the water storage member 2. Also, as shown in Figure 16, when three wall members 3 are connected to a Y-shaped water storage member 2, a hexagonal individual space S2 is formed, making it possible to manufacture a hexagonal road surface.

[0086] Furthermore, although the above embodiment did not explicitly state that a water storage space is formed in the wall member 3, a wall-side water storage space may also be formed in the wall member 3 in order to increase the amount of water stored in the road surface molding auxiliary member 1. In this case, for example, similar to the water storage member 2, a wall-side through hole that communicates with the internal wall-side water storage space may be formed in the upper part of the wall member 3, and the wall-side water storage space may be open at the lower part. In addition, communication holes may be formed in both the water storage member 2 and the wall member 3, respectively, which connect the water storage space S1 and the wall-side water storage space when the first engaging portion 24 and the second engaging portion 31 are engaged. In these cases, it is preferable to provide a planar rib extending outward (towards the individual space S2) from the lower end of the wall member 3 (side wall) in order to prevent the injected road surface molding material from flowing into the wall-side water storage space from the lower end of the wall member 3. Furthermore, in order to prevent the driven road surface molding material from flowing into the wall-side water storage space through the insertion hole H2, it is preferable to fit the tunnel member 5, as shown in Figure 17, into the insertion hole H2. Note that if a wall-side water storage space is also formed in the wall member 3 as described above, the wall member 3 will also correspond to the "water storage member" of the present invention, and therefore, anchor piles 10 may be attached to the wall member 3.

[0087] Furthermore, in the above embodiment, the water storage space S1 was open on the lower side of the water storage member 2, but it is possible to store water in the water storage space S1 even if it is not necessarily open.

[0088] Furthermore, in the above embodiment, the water storage member 2 was supported by three support members 21, but the support members 21 are not essential. Also, the inside of the support members 21 does not have to be hollow. In that case, the inside of the support member 21 will form the water storage space S1 on its own.

[0089] Furthermore, in the above embodiment, the wall member 3 is engaged with the water storage member 2, but it may also be integrated with the water storage member 2. In this case, as shown in Figure 18, the wall member 3 extends laterally from the water storage member 2, and the second engaging portion 31 can be configured to engage with the water storage member 2 or wall member 3 of other road surface shaping auxiliary members 1. When the wall member 3 is engaged with the wall member 3 of another road surface shaping auxiliary member 1, a configuration can be considered in which the second engaging portions 31 can engage with each other. When the wall member 3 is engaged with the water storage member 2 of another road surface shaping auxiliary member 1, a configuration can be considered in which it engages with the fourth engaging portion 26 formed on the water storage member 2. Then, when multiple road surface shaping auxiliary members 1 are engaged by the second engaging portion 31, individual spaces S2 surrounded by multiple water storage members 2 and multiple wall members 3 are formed. Even in this case, it is possible to shape road surfaces separated by each individual space S2, while also slightly increasing the degree of freedom in road surface shaping. Unlike in Figure 18, it is also possible to engage all of them with the second engaging parts 31, or to engage all of them with the second engaging parts 31 and the fourth engaging part 26.

[0090] Furthermore, as shown in Figure 19, a configuration in which the road surface shaping auxiliary member 1 is further equipped with a sub-water storage member 6 in order to store more water between it and the mounting surface is also conceivable.

[0091] As shown in the side cross-sectional view of Figure 19(a), the sub-water storage member 6 comprises a sub-water storage member body 61 in which a sub-water storage space S6 is formed internally, and a connecting pipe 62 extending from the upper part of the sub-water storage member body 61, communicating with the sub-water storage space S6, and having, or being capable of having, a sub-opening H3 formed at its upper part. In this embodiment, the sub-opening H3 is assumed to be formed in advance. Also, although three connecting pipes 62 are shown extending in Figure 19, there may be one or more than three.

[0092] The upper end of the sub-water storage member body 61 is lower than the upper ends of the water storage member 2 and the wall member 3. In this embodiment, the sub-water storage member body 61 and the connecting pipe 62 are designed so that their combined height is approximately the same as the height of the upper ends of the water storage member 2 and the wall member 3.

[0093] At least partially, the sub-water storage space S6 is open on the lower side of the sub-water storage member body 61. In this embodiment, the sub-water storage member body 61 is assumed to have a box shape with an open bottom.

[0094] During road surface molding, the sub-water storage members 6 are placed in the individual space S2, and road surface molding material such as concrete is poured into the individual space S2 (S2 in Figure 8). As the poured road surface molding material such as concrete hardens, a road surface is formed that has a drainage function, allowing water to flow from the opening H1 into the water storage space S1 and from the sub-opening H3 into the sub-water storage space S6.

[0095] In Figure 8, at S4, the lid member 5 is attached to the first groove 23 of the water storage member 2 and the second groove 32 of the wall member 3. However, it is preferable to also attach a lid member such as a rubber stopper to the sub-opening H3 of the sub-water storage member 6.

[0096] Furthermore, in this embodiment, as shown in Figure 19(b), the sub-water storage member 6 (sub-water storage member body 61) has a size that fits within the individual space S2 when viewed from above. As a result, as shown in Figure 19(a), a support layer A is formed in the portion surrounding the sub-water storage member 6 by the hardened road surface molding material.

[0097] Furthermore, as described above, the wall member 3 has an insertion hole H2 through which a rod-shaped reinforcing member B can be inserted, intersecting its extension direction, but the insertion hole H2 is formed in a position that does not face the sub-water storage member 6.

[0098] As shown in Figure 7, if the rod-shaped reinforcing members B are arranged in a grid pattern, it is conceivable to place the sub-water storage member 6 at the arrangement position C. However, if it is desired to place the sub-water storage member 6 in the center of the individual space S2, the insertion hole H2 should be formed at a position shifted to the left or right of the wall member 3 from the position shown in Figure 7.

[0099] With this configuration, as the road surface molding material such as concrete poured into the individual space S2 hardens, it is possible to form a road surface that allows water to flow from the opening H1 into the water storage space S1 and from the sub-opening H3 into the sub-water storage space S6, thereby enabling the storage of more water.

[0100] Furthermore, since the sub-water storage member 6 is sized to fit within the individual space S2 when viewed from above, a support layer A is formed by the hardened road surface molding material, thereby suppressing a decrease in the strength of the road surface.

[0101] Furthermore, in the wall member 3, at positions not facing the sub-water storage member 6, through holes H2 are formed so as to intersect with its extension direction, allowing rod-shaped reinforcing members B to be inserted. This makes it possible to place rod-shaped reinforcing members B, such as reinforcing bars, in individual spaces S2 while still arranging the sub-water storage member 6, thereby increasing the strength of the road surface when the road surface molding material hardens.

[0102] Furthermore, in the above embodiment, the road surface shaping 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 corresponds to the "placement surface".

[0103] Furthermore, in the above embodiment, resin or biodegradable plastic was used as the material for the water storage member 2 and the wall member 3, but other materials may also be used. [Explanation of symbols]
