Description

TECHNICAL FIELD The present invention relates to a road surface molding auxiliary member capable of easily molding a road surface capable of properly draining and storing surface water.

Conventionally, in a drain port unit 7 in which a hole 14 is formed in a bottom plate portion 8 and the upper side of the hole 14 is closed by a thin portion 19, water permeating through a gap 20 of the thin portion 19 flows through the hole 14. A technique has been proposed in which the liquid is discharged downward through a hole (see, for example, Patent Literature 1).

Generally, when a road surface is formed with concrete or the like, a water gradient is provided on the road surface in order to prevent the formation of puddles on the road surface due to surface water such as rainfall.

JP 2012-172506 A

However, when surface water is drained by a water gradient, the drainage is concentrated in a predetermined place (river, etc.), which may cause environmental problems such as flooding of the river.

In addition, when the road surface is made of concrete or the like, surface water does not permeate into the ground below the road surface, which may cause environmental problems such as ground subsidence due to lack of moisture in the ground.

Furthermore, apart from the environmental problems mentioned above, there is also a demand to make the concrete road surface level. becomes.

In Patent Document 1, it is essential that the bottom plate portion 8 is formed of porous concrete, and since it is originally related to the drain port unit, it can be used when concrete or the like is poured into the road surface. isn't it.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a road surface forming auxiliary member that can easily form a road surface capable of appropriately draining and storing surface water.

The present invention is a road surface molding auxiliary member used when molding a road surface, wherein a plurality of communicating pipes made of a flexible material are arranged in a mesh, and a plurality of first pipes are arranged in the plurality of meshes of the mesh. and a plurality of cylindrical portions each having a plurality of second through holes communicating with the plurality of first through holes and protruding from the main body portion. Spaces are provided between the plurality of communicating pipes arranged in a net shape, and the plurality of cylindrical portions protrude upward when the body portion is placed on the placement surface. The second through hole, the The auxiliary road surface molding member is characterized in that a drainage channel is formed by the first through hole and the communication pipe.

According to such a configuration, by driving a road surface forming material such as concrete into a portion other than the second through hole on the main body, drainage is performed by the cylindrical portion (second through hole) and the first through hole. A road surface with a channel is formed, and surface water on the road surface is drained to the mounting surface through this drainage channel. As a result, surface water seeps into the ground below the road surface, and environmental problems such as ground subsidence due to lack of moisture in the ground are suppressed. At this time, the existence of the space allows the flexible main body to easily bend in response to unevenness, so that the strength of the main body (particularly the communicating pipe) is reduced due to the influence of unevenness. , it is suppressed that the function as a drainage channel is impaired. Further, by using the road surface forming auxiliary member, it is possible to form a horizontal road surface because it is not necessary to provide a water gradient for drainage. As a result, surface water is prevented from being drained in a specific place, so environmental problems such as river flooding are suppressed, and it is also possible to meet the demand for a level road surface. It becomes possible. In addition, since concrete or the like is driven onto the body portion, the strength of the concrete or the like can be increased to the extent of the body portion. Therefore, if a body having a large thickness is adopted as the main body, it becomes possible to further increase the strength. Further, since the plurality of first through-holes are communicated by the communicating pipe, even if one of the first through-holes or the second through-hole is clogged with dust or the like from the outside, the other first through-holes can be Since water is drained from the first through-hole and the second through-hole, deterioration of the drainage function is suppressed. Moreover, since the surface water is dispersed throughout the main body by the communication pipe, it is possible to evenly permeate the surface water into the ground. Furthermore, when the amount of water in the ground is large, water is stored between the communication pipe and the mounting surface, so the amount of water in the ground is automatically adjusted.

Moreover, each communicating pipe preferably has a concave shape with an open bottom.

According to such a configuration, the concave shape with an open bottom can be easily deformed according to unevenness, so the strength of the communicating pipe is reduced due to the influence of unevenness, and the function as a drainage channel is impaired. is further suppressed.

Moreover, it is preferable to further include a rib extending substantially horizontally from the lower end of each communicating pipe toward the outside of the communicating pipe.

According to such a configuration, since the rib abuts on the mounting surface, the road surface forming material such as concrete is prevented from flowing into the communicating pipe from the space.

Further, a rod-shaped reinforcing member can be placed over the plurality of communicating pipes, and a holding member for holding the reinforcing member is provided at a position on the communicating pipe where the reinforcing member is to be placed. A groove is preferably formed.

According to such a configuration, it is not necessary to measure the position where the reinforcing member is to be placed or to fix the reinforcing member separately.

In addition, connecting portions are formed at the ends of the main body portions, and the connecting portion formed at the end portion of one of the main body portions and the connecting portion formed at the end portion of the other main body portion are different. The communicating pipes which are connectable to each other and formed in the one body portion communicate with the communicating pipe or the first through hole formed in the other body portion when the connecting portions are connected to each other. It is preferably formed in position.

With such a configuration, the road surface forming auxiliary member can be placed over a wide range, so that a large amount of surface water can be stored and the surface water can be drained into the ground over a wide range. It is possible to evenly impregnate the

According to such a configuration, it is possible to easily form a road surface capable of appropriately draining and storing surface water.

In addition, before the step of driving the concrete, mortar, cement, or asphalt, a first lid member for preventing the concrete, mortar, cement, or asphalt from entering each cylindrical portion is provided. It is preferable to further include the step of attaching to the tubular portion, and the step of removing the first lid member attached to each tubular portion after the step of driving the concrete, mortar, cement, or asphalt. .

With such a configuration, it is possible to reliably form a drainage channel on the road surface.

Further, the first lid member has an insertion portion that is inserted into the second through hole of the cylindrical portion, and a chamfered portion that spreads upward and outward from the upper portion of the insertion portion. preferably.

According to such a configuration, the concrete or the like that is poured into the position adjacent to the cylindrical portion is molded in a state along (chamfered) the shape of the chamfer forming portion, rather than at a right angle, which is likely to be damaged. As a result, damage to concrete or the like molded at a position adjacent to the cylindrical portion is suppressed.

A road surface molding auxiliary member 1 and a road surface molding method according to an embodiment of the present invention will be described below with reference to FIGS. 1 to 7. FIG.

A road surface molding auxiliary member 1 is used when road surface molding is performed using concrete, mortar, cement, or asphalt. As shown in FIGS. , is equipped with In the following, concrete, mortar, cement or asphalt are referred to as road molding materials.

The main body 2 is placed on a placement surface. In FIG. 1, the main body 2 is placed on a crushed stone Y (corresponding to the “placing surface”) laid on the ground X. Examples are given. As a material for the body portion 2, a material having flexibility is preferable, and a resin, a biodegradable plastic, or the like can be considered. However, when using asphalt as the road surface molding material, it is preferable to use a heat-resistant material.

As shown in FIG. 2, the main body 2 is formed by arranging a plurality of communicating pipes 21 made of a flexible material in a mesh shape. through holes 22 are formed respectively. A space S is provided between the plurality of communicating pipes 21 arranged in a mesh.

In the present embodiment, as shown in FIG. 2, the plurality of communicating pipes 21 are arranged to have a lattice shape, and the plurality of first through holes 22 are arranged in the vertical direction (the paper surface of FIG. 2). direction), and the entirety of the plurality of communicating tubes 21 has a substantially flat plate shape (sheet shape) having an upper surface 23 and a lower surface 24 .

Moreover, as shown in FIGS. 1 and 3, each communicating pipe 21 has a concave shape with an open bottom. As will be described later, water can be stored between the communicating pipes 21 and the mounting surface. 21 size, number, etc. are set.

As shown in FIGS. 2 and 3 , the main body 2 includes ribs 25 extending substantially horizontally from the lower ends of the communicating pipes 21 toward the outside of the communicating pipes 21 . Since the rib portion 25 extends substantially horizontally, when the main body portion 2 is placed on the placement surface (the crushed stone Y spread on the ground X), the placement surface (the crushed stone Y spread on the ground X) It comes into contact with crushed stone Y).

Also, the space S is defined by the ends of the ribs 25 . In the present embodiment, the space S is defined in a substantially rectangular shape when viewed from above (in FIG. 2, the rib portion 25 is shown only in the central portion to prevent complication).

As will be described later, road surface molding materials such as concrete, mortar, cement, or asphalt are driven onto the main body 2. These road surface molding materials are placed on a mounting surface (ground surface Since the crushed stone Y) laid on X is hardened together, the space S is preferably of a size that allows passage of the road surface molding material.

It is conceivable that the size of this space S is designed according to the road surface molding material used. For example, when ready-mixed concrete is used as a road surface molding material, the size of gravel used for ready-mixed concrete is roughly divided into two types: "maximum size 40 mm" and "maximum size 20 mm (25 mm)". 40 mm gravel is often used in civil engineering works, and 20 mm (25 mm) gravel is often used in building works.

Therefore, when using ready-mixed concrete, the space S is preferably of a size that gravel can pass through. For example, when gravel of 20 mm is used and the distance between the ends of the communicating pipes 21 facing each other is 40 mm, as shown in FIG. It is conceivable to set

A rod-shaped reinforcing member such as a reinforcing bar can be placed over the plurality of communicating pipes 21, and a holding member for holding the reinforcing member is provided at a position on the communicating pipe 21 where the reinforcing member is to be placed. A groove 26 is formed (in FIG. 2, the holding groove 26 is shown only partially to prevent complication).

As shown in FIG. 2, connecting portions 27 are formed at the ends of the body portion 2. As shown in FIG. The connection portions 27 formed at the ends of the main body portions 2B are connectable to each other, and the communicating pipe 21 of one main body portion 2A is connected to the other main body portion 2B when the connection portions 27 are connected to each other. It is formed at a position communicating with the communicating pipe 21 .

Preferably, the connection portions 27 are provided on each side of the main body portion 2, and can be connected to a desired number of other main body portions 2 (road surface molding auxiliary members 1) in four directions. Various methods of connecting the connecting portion 27 are conceivable, but the connecting portion 27 has some play when the body portions 2 are connected to each other so as to be able to cope with unevenness described later. It is preferably designed to

As shown in FIGS. 1 and 2, the plurality of cylindrical portions 3 has a plurality of second through holes 31 communicating with the plurality of first through holes 22, respectively. Each one stands out. The plurality of cylindrical portions 3 protrude upward when the body portion 2 is placed on the placement surface. As the material of the cylindrical portion 3, similarly to the body portion 2, a material having flexibility is preferable, and resins, biodegradable plastics, and the like can be considered. However, when using asphalt as the road surface molding material, it is preferable to use a heat-resistant material.

Further, as described above, reinforcing members such as reinforcing bars can be laid over the plurality of communicating pipes 21, and the height of the cylindrical portion 3 is preferably higher than the diameter of the reinforcing members. . When the holding groove 26 is formed, the height of the cylindrical portion 3 should be higher than (the diameter of the reinforcing member-the depth of the holding groove 25).

Under the above configuration, by driving a road surface molding material (concrete Z in FIG. 1) into a portion other than the second through hole 31 on the main body 2 (up to near the tip of the cylindrical portion 3 in FIG. 1), A road surface on which drainage channels (second through holes 31 and first through holes 22) are formed is molded, and surface water on the road surface flows to the mounting surface (crushed stone Y and ground surface X) through the drainage channels. drained.

As a result, surface water seeps into the ground below the road surface, thereby preventing environmental problems such as ground subsidence caused by insufficient moisture in the ground. Further, by using the road surface forming auxiliary member 1, it is possible to form a horizontal road surface because it is not necessary to provide a water gradient for drainage. As a result, it is possible to prevent surface water from being concentrated and drained in a predetermined place, thereby suppressing the occurrence of environmental problems such as river flooding and meeting the demand for level road surfaces. It becomes possible.

Further, in the present embodiment, the communication pipe 21 communicates between the first through holes 22 . As a result, even if one of the first through holes 22 or the second through holes 31 is clogged with dust or the like from the outside, water is drained from the other first through holes 22 or the second through holes 31. As a result, deterioration of the drainage function is suppressed. In addition, since the surface water is dispersed throughout and around the main body 2 by the communicating pipe 21, it is possible to evenly soak the surface water into the ground. Furthermore, when the amount of water in the ground is large, water is stored between the communicating pipe 21 and the mounting surface, so the amount of water in the ground is automatically adjusted.

By the way, the surface on which the crushed stone Y or the like is laid on the ground X is uneven to some extent. Therefore, when the concrete Z or the like is placed on the road surface molding auxiliary member 1 placed on the placement surface, the main body 2 is distorted due to unevenness or under a strong load, and the concrete around the main body 2 is deformed. It will be hardened by Z etc., and there exists a possibility that the intensity|strength of the main-body part 2 may fall.

However, in the present embodiment, a space S is provided between the plurality of communicating pipes 21 arranged in a net shape. It is possible to bend easily by Therefore, it is suppressed that the strength of the communication pipe 21 is lowered due to the influence of unevenness, and the function as a drainage channel is impaired. Furthermore, since each communicating pipe 21 has a concave shape with an open lower portion that can be easily deformed in response to unevenness, this also reduces the strength of the communicating pipe 21, resulting in a drainage channel. It is suppressed that the function as is impaired.

On the other hand, as described above, the communication pipes 21 have a concave shape with an open bottom, and the space S is provided between the communication pipes 21, so that the road surface forming material such as concrete is driven. At this time, the road surface molding material may flow into the communicating pipe 21 from the space S, impairing its function as a drainage channel.

However, in the present embodiment, the rib portion 25 extends from the lower end of each communicating pipe 21 toward the outside of the communicating pipe 21 in a substantially horizontal direction, and the rib portion 25 is positioned on the mounting surface (ground surface X Since it abuts on the crushed stone Y) laid on the wall, the road surface molding material is suppressed from flowing into the communicating pipe 21 from the space S.

As shown in FIG. 5, the road surface molding material is driven in a state in which the first lid member 4 for driving is attached (fitted) to the upper end of the second through hole 31 of the cylindrical portion 3. preferably

As shown in FIG. 5 , the first cover member 4 includes a first insertion portion 41 inserted into the second through hole 31 of the tubular portion 3 , and an upper and outer side from the upper portion of the first insertion portion 41 . and a chamfer formation 42 that widens toward. In FIG. 5 , the first insertion portion 41 has a columnar shape with substantially the same diameter as the second through hole 31 . The chamfer forming portion 42 has a truncated cone shape, and has a structure in which the upper base is attached to the upper portion of the first insertion portion 41 .

After removing the first lid member 4, it is preferable to insert the second lid member 5 for finishing into the second through-hole 31 of the tubular portion 3, and complete the road surface in this state.

As shown in FIG. 6 , the second lid member 5 includes a cylindrical second insertion portion 51 that is inserted into the second through hole 31 of the cylindrical portion 3 and an opening that is smaller than the second through hole 31 . and a top surface portion 53 in which a third through hole 52 having a diameter is formed. As a result, the second penetration of the cylindrical portion 3 via the third through hole 52 and the second insertion portion 51 is suppressed while preventing objects other than surface water from falling into the second through hole 31 . Surface water will flow into the hole 31 . As the third through-hole 52, an appropriate size and shape (net-like, etc.) may be used depending on the situation (a place where many people wearing high heels pass through, a place where coins are likely to be dropped, etc.).

Next, a road surface molding method using the road surface molding auxiliary member 1 will be described with reference to the flow chart of FIG.

First, the road surface shaping auxiliary member 1 is placed on the placement surface so that the plurality of cylindrical portions 3 face upward (S1).

Subsequently, the first lid member 4 is attached to each tubular portion 3 (S2).

Subsequently, a road surface forming material such as concrete is driven into the portion other than the second through hole 31 of the cylindrical portion 3 on the main body portion 2 (S3). In this step, it is preferable to drive the road surface forming material in such an amount that the entire chamfer forming portion 42 of the first lid member 4 is not filled.

Subsequently, the first lid member 4 attached to each cylindrical portion 3 is removed (S4). Even if the road surface molding material is not completely hardened, the first lid member 4 can be removed as long as the road surface molding material is hardened to such an extent that the shape thereof does not collapse.

Finally, the second cover member 5 is attached to each tubular portion 3 (S5) to complete the road surface.

As a result, a highly safe road surface is formed in which the tubular portion 3 does not protrude from the road surface.

A space S is provided between the plurality of communicating pipes 21 formed.

According to such a configuration, the cylindrical portion 3 (the second through hole 31) and the first through hole 31 are formed by driving a road surface forming material such as concrete into the portion other than the second through hole 31 on the main body portion 2. A road surface having a drainage channel formed by the through holes 22 is formed, and surface water on the road surface is drained to the mounting surface through this drainage channel. As a result, surface water seeps into the ground below the road surface, and environmental problems such as ground subsidence due to lack of moisture in the ground are suppressed. At this time, due to the presence of the space S, the flexible main body 2 can easily bend in response to unevenness, so that the main body 2 (especially the communicating pipe 21) is affected by the unevenness. It is suppressed that the strength is lowered and the function as a drainage channel is impaired. Further, by using the road surface forming auxiliary member 1, it is possible to form a horizontal road surface because it is not necessary to provide a water gradient for drainage. As a result, surface water is prevented from being drained in a specific place, so environmental problems such as river flooding are suppressed, and it is also possible to meet the demand for a level road surface. It becomes possible. Further, since concrete or the like is driven onto the main body portion 2, the strength of the concrete or the like can be increased to the extent of the main body portion 2. - 特許庁Therefore, if a thicker body is used as the main body 2, the strength can be further increased. Further, since the plurality of first through-holes 22 are communicated by the communicating pipe 21, even if one of the first through-holes 22 or the second through-holes 31 is clogged with dust or the like from the outside, Since water is drained from other first through-holes 22 and second through-holes 31, deterioration of the draining function is suppressed. In addition, since the surface water is dispersed throughout the main body 2 by the communicating pipe 21, it is possible to evenly soak the surface water into the ground. Furthermore, when the amount of water in the ground is large, water is stored between the communicating pipe 21 and the mounting surface, so the amount of water in the ground is automatically adjusted.
