Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the above road surface forming auxiliary member, since the formed road surface becomes a single slab, it is easy to be deformed and cracks are likely to occur in prominent portions of the road surface.

[0005] Therefore, an object of the present invention is to provide a road surface forming auxiliary member capable of forming a road surface in which a drainage channel is formed and cracking is suppressed.

Means for Solving the Problems

[0006] The present invention relates to a road surface forming auxiliary member that is placed on a mounting surface when forming a road surface, comprising a main body portion in which at least two water storage members extending substantially horizontally intersect, and engaging portions provided on the end side of the water storage members, wherein the water storage members comprise a pair of wall portions extending substantially horizontally and facing each other, and a plurality of connecting portions that partially connect the upper parts of the pair of wall portions, wherein a through hole is formed in the upper part of the pair of wall portions where the connecting portions are not present, and the pair of wall portions The lower parts of the two intersecting water storage members are at least partially open, the water storage spaces of the two intersecting water storage members are in communication, the engaging portion of one road surface shaping auxiliary member is capable of engaging with the engaging portion of another road surface shaping auxiliary member, the engagement of the engaging portions forms a driving space surrounded by the multiple water storage members, and the road surface shaping material driven into the driving space hardens to form a road surface into which water can flow from the through holes into the water storage spaces.

[0007] With this configuration, the road surface molding material poured into the pouring space hardens, making it possible to form a road surface with drainage function that allows water to flow into the water storage space through the through-holes. In this case, since the pouring space is defined by multiple water storage members, the road surface is formed in sections for each pouring space rather than as a single monolith, thus suppressing distortion and cracking of the road surface. Furthermore, since the connection part partially connects the upper parts of a pair of wall sections to form the through-holes, the connection part prevents large debris from flowing into the water storage space, while allowing rainwater to flow into the water storage space through the through-holes. Moreover, since the pouring space is formed by combining multiple road surface molding auxiliary members, and each road surface molding auxiliary member does not occupy the space required for the pouring space, the storage space required when the road surface molding auxiliary members are not in use can be reduced, and transportation is also made easier.

[0008] Furthermore, according to another aspect of the present invention, a road surface molding method using the above-mentioned road surface molding auxiliary member is provided. [Effects of the Invention]

[0009] According to the road surface molding auxiliary member and road surface molding method of the present invention, it is possible to mold a road surface in which drainage channels are formed and cracking is suppressed. [Brief explanation of the drawing]

[0011] Hereinafter, the road surface molding auxiliary member 1 and road surface molding method according to embodiments of the present invention will be described with reference to Figures 1 to 9.

[0012] The road surface forming auxiliary member 1 is arranged on a placement surface (such as crushed stones laid on the ground) during the formation of a road surface using a road surface forming material such as concrete, mortar, cement, or asphalt. As shown in FIGS. 1 and 2, it includes a main body portion 2 and an engaging portion 3.

[0013] The main body portion 2 has a configuration in which at least two water storage members 21 extending in a substantially horizontal direction intersect. In this embodiment, it is assumed that the two water storage members 21 intersect at a substantially right angle at their central portions. [[ID=​​​​​​​​​​​​​​​​​​​​​​

[0020] As a closing member, a long piece of resin or the like with a width that fits just within the groove 24 can be considered.

[0021] As shown in Figure 3, the lower parts of the pair of wall sections 22 are at least partially open. In this embodiment, the lower parts of the pair of wall sections 22 are assumed to be almost entirely open.

[0022] As shown in Figures 3 and 4, the engaging portion 3 of one road surface shaping auxiliary member 1 can engage with the engaging portion 3 of another road surface shaping auxiliary member 1.

[0023] In this embodiment, as shown in Figure 2, the engaging portion 3 protrudes from one side of the water storage member 21 in the extending direction. When the two engaging portions 3 are engaged, they abut each other at their sides, and the tip of each engaging portion 3 abuts against the end of the water storage member 1 of the other road surface shaping auxiliary member 1 (the portion where the engaging portion 3 does not protrude). Details of the engagement of the two engaging portions 3 will be described later.

[0024] Then, when the engaging portions 3 engage with each other, a driving space S2 surrounded by multiple water storage members 21 is formed, as shown in Figure 4.

[0025] Concrete or other road surface molding materials are poured into the pouring space S2. As the poured road surface molding materials harden, a road surface with drainage function is formed that allows water to flow into the water storage space S1 through the through holes H. The method of forming the road surface will be described later.

[0026] In this embodiment, the ends of the engaging portion 3 and the ends of the water storage member 1 where the engaging portion does not protrude are closed off, and as shown in Figure 3, even when the engaging portions 3 are fitted together, the water storage spaces S1 are not directly connected to each other.

[0027] Furthermore, in this embodiment, as shown in Figure 1, in order 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 21, a planar rib 25 is provided that extends outward (towards the pouring space S2) from the lower end of the water storage member 21 (wall portion 22).

[0028] As shown in Figure 1, a recess 26 is formed on the end side of the water storage member 21, and as shown in Figure 5, the recess 26 is formed in a position where a rod-shaped reinforcing member B can be placed across the two recesses 26 when the engaging portions 3 are engaged with each other. Figure 1 shows an example in which the recess 26 is formed on the engaging portion 3.

[0029] As will be described later, road surface molding material is poured into the pouring space S2, but the rod-shaped reinforcing members B are intended to work together with the hardened road surface molding material to increase the overall strength of the road surface, and for example, reinforcing bars can be used. Figure 5 shows an example in which rod-shaped reinforcing bars are arranged in a grid pattern.

[0030] Furthermore, by placing the rod-shaped reinforcing member B across the two recesses 26, the displacement of the two road surface shaping auxiliary members 1 due to unevenness or other factors is suppressed.

[0031] In this embodiment, as shown in Figure 1, the water storage member 21 is also provided with an engagement auxiliary projection 31 at its end, separate from the engagement portion 3. The engagement auxiliary projection 31 of one road surface molding auxiliary member 1 can engage with the engagement auxiliary projection 31 of another road surface molding auxiliary member 1, thereby assisting the engagement of the engagement portions 3.

[0032] Furthermore, the recessed portion 26 also functions to form a crack-preventing joint, but the details of this will be described later.

[0033] As shown in Figure 6, a cover member 4 can be fitted over the upper part of the recess 26, covering the rod-shaped reinforcing member B, with its upper end connected to the upper part of the water storage member 21.

[0034] In this embodiment, as shown in Figure 7, a cover side groove 41 continuous with the groove 24 is formed on the upper part of the cover member 4.

[0035] For the cover member 4, resin or biodegradable plastic may be used. However, if asphalt is used as the road surface molding material, it is preferable to use a heat-resistant material.

[0036] In this way, the road surface is formed with multiple road surface forming auxiliary members 1 combined together.

[0037] 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.

[0038] First, the engaging portions 3 of four or more road surface shaping auxiliary members 1 are engaged with each other on the mounting surface (S1). This creates a driving space S2 surrounded by four water storage members 21.

[0039] Next, a rod-shaped reinforcing member B is placed across the two overlapping recesses 26 formed by the engagement of the engaging portions 3 (S2), a cover member 4 is fitted onto the upper part of the recesses 26 (S3), and a closing member is fitted into the groove 24 of the water storage member 21 and the cover side groove 41 of the cover member 4 (S4).

[0040] Next, the road surface molding material is driven into the driving space S2 (S5). Specifically, the road surface molding material is driven up to the height of the upper part of the water storage member 21. However, if the road surface molding material can be driven in without flowing into the through hole H, step S4 above may be omitted.

[0041] Subsequently, once the road surface molding material has hardened (S6:YES), the blocking member is removed (S7), and the road surface with the drainage channel is completed as shown in Figure 9 (S8). The blocking member may also be removed once the road surface molding material has hardened to the point where it does not flow.

[0042] The road surface formed in this way is not a single solid block, but rather divided into sections with embedded spaces S2, thus suppressing strain and cracking.

[0043] Furthermore, the road surface molding material poured into the pouring space S2 also flows into the recesses 26, so the road surface molding material poured into adjacent pouring spaces S2 will bond to each other via the recesses 26. In this case, the portion of the hardened road surface molding material that hardens within the recesses 26 functions as a crack-preventing joint and is more prone to cracking than other parts, thus also suppressing cracking of the road surface.

[0044] Furthermore, if the cover member 4 is not fitted in S3, adjacent embedded spaces S2 will communicate with each other at the upper part of the recess 26, and the connected parts will be prone to cracking. However, since the upper end of the cover member 4 is connected to the upper part of the water storage member, an independent road surface is formed for each embedded space S2, thus suppressing cracking of the road surface.

[0045] As a result of the road surface being formed in this manner, surface water that flows into the water storage space S1 through the through-holes H 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 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.

[0046] Thus, with the road surface shaping auxiliary member 1 and road surface shaping method according to this embodiment, 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 can be used by individuals for DIY road surface shaping in parking lots and other areas.

[0047] As described above, in the road surface molding auxiliary member 1 and road surface molding method according to this embodiment, through holes H communicating with the water storage space S1 are formed in the upper parts of the pair of wall portions 22 where there are no connecting portions 23, and when the engaging portions 3 engage with each other, a driving space S2 surrounded by multiple water storage members 21 is formed.

[0048] With this configuration, the road surface molding material poured into the pouring space S2 hardens, making it possible to form a road surface with drainage function that allows water to flow into the water storage space S1 through the through-holes H. In this case, since the pouring space S2 is defined by multiple water storage members 21, the road surface is formed in sections divided into pouring spaces S2 rather than as a single monolith, thus suppressing distortion and cracking of the road surface. Furthermore, since the through-holes H are formed by partially connecting the upper parts of a pair of wall sections 22 with the connecting section 23, large debris and other objects are prevented from flowing into the water storage space S1 by the connecting section 23, while rainwater and other liquids can flow into the water storage space through the through-holes H. Moreover, since the pouring space S2 is formed by combining multiple road surface molding auxiliary members 1, a single road surface molding auxiliary member 1 does not occupy the space of the pouring space S2, thus reducing the storage space required for unused road surface molding auxiliary members 1 and making transportation easier.

[0049] Furthermore, in the road surface shaping auxiliary member 1 according to this embodiment, the recesses 26 are formed in a position where a rod-shaped reinforcing member B can be placed across the two recesses 26 when the engaging portions 3 are engaged with each other.

[0050] With this configuration, it becomes possible to place rod-shaped reinforcing members B, such as reinforcing bars, on the recesses 26, thereby increasing the strength of the road surface when the road surface molding material hardens. Furthermore, since the rod-shaped reinforcing members B are placed across the two recesses 26, displacement of the two road surface molding auxiliary members 1 due to unevenness or other factors is suppressed.

[0051] Furthermore, in the road surface shaping auxiliary member 1 according to this embodiment, a cover member 4 can be fitted over the upper part of the recess 26, with the upper end of the cover member 4 being connected to the upper part of the water storage member 21.

[0052] With this configuration, the upper end of the cover member 4 is connected to the upper part of the water storage member 21, so that the road surface formed in adjacent pouring spaces S2 is not connected, that is, an independent road surface is formed for each pouring space S2, thus suppressing road surface distortion and cracking.

[0053] Furthermore, in the road surface shaping auxiliary member 1 according to this embodiment, a groove 24 is formed on the upper part of the water storage member 21, which is fitted along its extending direction, into which a closing member can be fitted to close the through hole H.

[0054] With this configuration, a sealing member such as rubber can be fitted to the upper part of the water storage member 21, that is, the upper part of the through hole H. By fitting the sealing member before driving in the road surface molding material, it is possible to prevent the road surface molding material from flowing into the water storage space S1 when the road surface molding material is driven in.

[0055] Furthermore, the road surface molding auxiliary member and road surface molding 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.

[0056] For example, one might want to drain surface water that has flowed into the reservoir space S1 to a designated location.

[0057] Therefore, as shown in Figures 10 and 11, a configuration is also possible in which "a water guide member 5 having a water guide space S3 along the water storage member 21 can be arranged at the lower part of the main body 2, and when the water guide member 5 is arranged at the lower part of the main body 2, the water guide space S3 is in communication with the water storage space S1, and when one road surface molding auxiliary member 1 and another road surface molding auxiliary member 1 are engaged, the water guide space S3 of the water guide member 5 arranged at the lower part of one road surface molding auxiliary member 1 is in communication with the water guide space S3 of the water guide member 5 arranged at the lower part of the other road surface molding auxiliary member 1."

[0058] Figure 10 shows an example in which the water guiding member 5 has a groove with a width corresponding to the water storage space S1, and the inside of this groove functions as a water guiding space S3. Furthermore, when the water guiding member 5 is placed at the lower part of the main body 2, it is preferable that it is fixed to the main body 2. In addition, the water guiding members 5 may engage with each other, or the water guiding function can be obtained even if they only come into contact with each other to the extent that "one road surface shaping auxiliary member 1 and another road surface shaping auxiliary member 1 engage with each other and cause the water guiding members 5 to come into contact with each other."

[0059] With this configuration, the water guide member 5 makes it possible to guide the surface water that has flowed into the water storage space S1 to the desired discharge location. Since the surface water thus guided can be stored at the discharge location, it becomes possible to efficiently store rainwater in water scarce areas.

[0060] Furthermore, although the above embodiment included a recess 26, a hole may be used instead of the recess 26, and the hole may be formed in a position where a rod-shaped reinforcing member B can be placed across the two holes when the engaging portions 3 are engaged with each other. In this case, since the rod-shaped reinforcing member is not placed from above, by providing a member equivalent to the cover member 4 on the engaging portion 3 (or the end of the water storage member 21) from the beginning, it becomes possible to form an independent road surface for each driving space S2.

[0061] Furthermore, in the above embodiment, the rod-shaped reinforcing member B was placed across the two recesses 26, but it is not necessary to place the rod-shaped reinforcing member B across them. Moreover, the recesses 26 do not even need to be provided. In this case as well, it is conceivable to provide a member corresponding to the cover member 4 from the beginning at the engaging portion 3 (or the end of the water storage member 21).

[0062] Furthermore, in the above embodiment, the ends of the engaging portion 3 and the ends of the water storage member 1 where the engaging portion does not protrude are closed, and even when the engaging portions 3 are fitted together, the water storage spaces S1 are not in communication with each other. However, the ends of the engaging portion 3 and the ends of the water storage member 1 where the engaging portion does not protrude may be open, and the water storage spaces S1 may be in communication with each other when the engaging portions 3 are fitted together.

[0063] 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".

[0064] Furthermore, in the above embodiment, resin or biodegradable plastic was used as the material for the main body 2, but other materials may also be used. [Explanation of Symbols]
