Description

本発明は、地表水を適切に排水及び貯水することのできる路面を容易に成型することが可能な路面成型補助部材に関する。 The present invention relates to a road surface forming auxiliary member capable of easily forming a road surface capable of appropriately draining and storing surface water.

従来より、底板部８に孔部１４が形成され、孔部１４の上方側が肉薄部１９によって塞がれた排水口ユニット７において、肉薄部１９の空隙２０から透水した水分が、孔部１４を介して下部へ排出される技術が提案されている（例えば、特許文献１参照）。 Conventionally, in the drainage port unit 7 in which the hole portion 14 is formed in the bottom plate portion 8 and the upper side of the hole portion 14 is closed by the thin portion 19, the water permeated from the void 20 of the thin portion 19 causes the hole portion 14. A technique has been proposed in which the water is discharged to the lower part via the same (see, for example, Patent Document 1).

また、一般的に、コンクリート等で路面を成型する際には、路面上に降雨等の地表水による水溜まりができてしまうことを防止するために、路面に水勾配を設けている。 Further, in general, when the road surface is molded from concrete or the like, a water gradient is provided on the road surface in order to prevent water pools due to surface water such as rainfall from forming on the road surface.

特開２０１２－１７２５０６号公報Japanese Unexamined Patent Publication No. 2012-172506

しかしながら、水勾配によって地表水の排水を行う場合、所定の場所（河川等）に排水が集中してしまい、河川の氾濫等の環境問題が生じるおそれがある。 However, when surface water is drained due to a water gradient, the drainage is concentrated in a predetermined place (river, etc.), which may cause environmental problems such as flooding of the river.

また、コンクリート等で路面を成型した場合、路面の下方にある地中に地表水がしみ込まないため、地中の水分不足による地盤沈下等の環境問題が生じるおそれもある。 In addition, when the road surface is molded from concrete or the like, the surface water does not soak into the ground below the road surface, which may cause environmental problems such as land subsidence due to lack of water in the ground.

更に、上記した環境問題とは別に、コンクリート路面を水平にしたいという要望もあり、その場合には、排水性（水溜まりの防止）と（路面の）水平性という相反する要素を両立させる技術が必要となる。 Furthermore, apart from the above-mentioned environmental problems, there is also a request to make the concrete road surface horizontal, and in that case, a technology that balances the contradictory elements of drainage (prevention of puddle) and horizontality (of the road surface) is required. Will be.

特許文献１では、底板部８がポーラスコンクリートで形成されていることが必須になってしまう上に、そもそも排水口ユニットに関するものであるため、コンクリート等を打ち込んで路面を成型する際に使用できるものではない。 In Patent Document 1, it is essential that the bottom plate portion 8 is made of porous concrete, and since it is related to the drainage port unit in the first place, it can be used when concrete or the like is driven into the road surface. is not it.

そこで、本発明は、地表水を適切に排水及び貯水することのできる路面を容易に成型することが可能な路面成型補助部材を提供することを目的としている。 Therefore, an object of the present invention is to provide a road surface molding auxiliary member capable of easily molding a road surface capable of appropriately draining and storing surface water.

本発明は、路面の成型時に使用される路面成型補助部材であって、可撓性を有する素材で形成された複数の連通管が網状に配置され、前記網の複数の網目に複数の第１の貫通孔がそれぞれ形成された本体部と、前記複数の第１の貫通孔にそれぞれ連通する複数の第２の貫通孔を有し、前記本体部からそれぞれ突出した複数の筒状部と、を備え、前記網状に配置された複数の連通管間には空間が設けられており、前記複数の筒状部は、前記本体部が載置面上に載置された状態で上方に向けて突出しており、前記載置面上に載置された前記本体部上の前記第２の貫通孔以外の部分にコンクリート、モルタル、セメント、又は、アスファルトが打ち込まれることで、前記第２の貫通孔、前記第１の貫通孔及び前記連通管により排水路が形成されることを特徴とする路面成型補助部材を提供している。 The present invention is a road surface molding auxiliary member used at the time of molding a road surface, in which a plurality of communication pipes made of a flexible material are arranged in a mesh pattern, and a plurality of first meshes of the mesh are arranged. A main body portion in which each of the through holes is formed, and a plurality of tubular portions each having a plurality of second through holes communicating with the plurality of first through holes and protruding from the main body portion. A space is provided between the plurality of communication pipes arranged in a mesh pattern, and the plurality of tubular portions project upward with the main body portion mounted on the mounting surface. The second through hole is formed by driving concrete, mortar, cement, or asphalt into a portion other than the second through hole on the main body portion placed on the above-mentioned mounting surface. Provided is a road surface forming auxiliary member characterized in that a drainage channel is formed by the first through hole and the communication pipe.

このような構成によれば、本体部上の第２の貫通孔以外の部分にコンクリート等の路面成型材料を打ち込むことで、筒状部（第２の貫通孔）及び第１の貫通孔により排水路が形成された路面が成型され、路面上の地表水は、この排水路を介して載置面に排水される。これにより、路面の下方にある地中に地表水がしみ込むこととなり、地中の水分不足により地盤沈下等の環境問題が生じることが抑制される。この際、空間の存在により、可撓性を有する本体部は、不陸に応じて容易に撓むことが可能であるため、不陸の影響により本体部（特に連通管）の強度が低下し、排水路としての機能が損なわれることが抑制される。また、路面成型補助部材を用いることで、排水のための水勾配を設ける必要がなくなるので、水平な路面を成型することが可能となる。これにより、地表水が所定の場所に集中して排水されることが防止されるので、河川の氾濫等の環境問題が生じることも抑制されると共に、路面を水平にしたいという要望に応えることも可能となる。また、コンクリート等は、本体部上に打ち込まれるので、本体部の分までコンクリート等の強度を増加させることができる。従って、本体部として、厚みの大きいものを採用すれば、より強度を増加させることが可能となる。また、複数の第１の貫通孔間が連通管により連通されているので、一の第１の貫通孔や第２の貫通孔が外部からの粉塵等によって目詰まりしたとしても、他の第１の貫通孔や第２の貫通孔から排水が行われるので、排水機能が損なわれることが抑制される。また、地表水は、連通管により本体部全体に分散されるので、地表水を地中に満遍なくしみ込ませることが可能となる。更に、地中の水量が多い場合には、連通管と載置面との間に貯水されるので、地中の水量が自動的に調節される。 According to such a configuration, by driving a road surface molding material such as concrete into a portion other than the second through hole on the main body portion, drainage is performed by the tubular portion (second through hole) and the first through hole. The road surface on which the road is formed is molded, and the 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 land subsidence due to lack of water in the ground are suppressed. At this time, due to the presence of space, the flexible main body can be easily bent in response to non-landing, so that the strength of the main body (particularly the communication pipe) decreases due to the influence of non-landing. , It is suppressed that the function as a drainage channel is impaired. Further, by using the road surface forming auxiliary member, it is not necessary to provide a water gradient for drainage, so that it is possible to form a horizontal road surface. As a result, the surface water is prevented from being drained in a predetermined place, so that environmental problems such as flooding of rivers are suppressed and the demand for leveling the road surface can be met. It will be possible. Further, since the concrete or the like is driven onto the main body portion, the strength of the concrete or the like can be increased to the extent of the main body portion. Therefore, if a thick body is used as the main body, the strength can be further increased. Further, since the plurality of first through holes are communicated with each other by a communication pipe, even if the first through hole or the second through hole is clogged by dust or the like from the outside, the other first through hole is used. Since drainage is performed from the through hole or the second through hole, the drainage function is suppressed from being impaired. Further, since the surface water is dispersed throughout the main body by the communication pipe, the surface water can be evenly permeated into the ground. Further, when the amount of water in the ground is large, the water is stored between the communication pipe and the mounting surface, so that the amount of water in the ground is automatically adjusted.

また、各連通管は、下部が開放された凹形状を有していることが好ましい。 Further, it is preferable that each communication pipe has a concave shape with an open lower portion.

このような構成によれば、下部が開放された凹形状は不陸に応じて容易に変形することができるので、不陸の影響により連通管の強度が低下し、排水路としての機能が損なわれることが更に抑制される。 According to such a configuration, the concave shape with the open lower part can be easily deformed in response to the non-landing, so that the strength of the communication pipe is reduced due to the influence of the non-landing, and the function as a drainage channel is impaired. Is further suppressed.

また、各連通管の下端部から当該連通管の外側に向けて略水平方向に延出したリブ部を更に備えたことが好ましい。 Further, it is preferable to further provide a rib portion extending in a substantially horizontal direction from the lower end portion of each communication pipe toward the outside of the communication pipe.

このような構成によれば、リブ部が載置面に当接するので、コンクリート等の路面形成材料が空間から連通管内に流れ込むことが抑制される。 According to such a configuration, since the rib portion comes into contact with the mounting surface, it is possible to prevent the road surface forming material such as concrete from flowing from the space into the communication pipe.

また、複数の連通管上には棒状の補強部材を掛け渡して載置可能であり、前記連通管上の前記補強部材が載置されるべき位置には、前記補強部材を保持するための保持溝が形成されていることが好ましい。 Further, a rod-shaped reinforcing member can be hung and placed on the plurality of communication pipes, and the reinforcing member is held at a position on the communicating pipe where the reinforcing member should be placed. It is preferable that the groove is formed.

このような構成によれば、補強部材を載置する位置を測定したり、補強部材を別途固定する労力が不要となる。 With such a configuration, it is not necessary to measure the position where the reinforcing member is placed or to separately fix the reinforcing member.

また、前記本体部の端部には、接続部が形成されており、一の前記本体部の端部に形成された接続部と他の前記本体部の端部に形成された接続部とは互いに接続可能であり、前記一の本体部に形成された連通管は、前記接続部同士が接続された際に、前記他の本体部に形成された連通管又は第１の貫通孔と連通する位置に形成されていることが好ましい。 Further, a connection portion is formed at the end portion of the main body portion, and the connection portion formed at one end portion of the main body portion and the connection portion formed at the other end portion of the main body portion are different from each other. The communication pipes that can be connected to each other and are formed in the one main body portion communicate with the communication pipes formed in the other main body portion or the first through hole when the connection portions are connected to each other. It is preferably formed at the position.

このような構成によれば、広い範囲に渡って路面成型補助部材を載置することができるので、多くの地表水を貯水することが可能となると共に、広い範囲に渡って地表水を地中に満遍なくしみ込ませることが可能となる。 According to such a configuration, since the road surface molding auxiliary member can be placed over a wide range, it is possible to store a large amount of surface water and to store the surface water in the ground over a wide range. It is possible to soak it evenly.

また、本発明の別の観点によれば、可撓性を有する素材で形成された複数の連通管が網状に配置され、前記網の複数の網目に複数の第１の貫通孔がそれぞれ形成された本体部と、前記複数の第１の貫通孔にそれぞれ連通する複数の第２の貫通孔を有し、前記本体部からそれぞれ突出した複数の筒状部と、を有し、前記網状に配置された複数の連通管間には空間が設けられており、前記複数の筒状部は、前記本体部が載置面上に載置された状態で上方に向けて突出している路面成型補助部材を用いた路面成型方法であって、前記複数の筒状部が上方になるように前記路面成型補助部材を載置面上に載置する工程と、前記本体部上の前記第２の貫通孔以外の部分にコンクリート、モルタル、セメント、又は、アスファルトを打ち込む工程と、を備えたことを特徴とする路面成型方法を提供している。 Further, according to another aspect of the present invention, a plurality of communication pipes made of a flexible material are arranged in a mesh pattern, and a plurality of first through holes are formed in the plurality of meshes of the mesh. It has a main body portion and a plurality of second through holes communicating with each of the plurality of first through holes, and has a plurality of tubular portions each protruding from the main body portion, and is arranged in the mesh pattern. A space is provided between the plurality of communication pipes, and the plurality of tubular portions are road surface forming auxiliary members that project upward with the main body portion mounted on the mounting surface. In the road surface molding method using the above, the step of mounting the road surface molding auxiliary member on the mounting surface so that the plurality of tubular portions face upward, and the second through hole on the main body portion. The present invention provides a road surface molding method characterized by comprising a step of driving concrete, mortar, cement, or asphalt into a portion other than the above.

このような構成によれば、地表水を適切に排水及び貯水することのできる路面を容易に成型することが可能となる。 With such a configuration, it becomes possible to easily form a road surface capable of appropriately draining and storing surface water.

また、前記コンクリート、モルタル、セメント、又は、アスファルトを打ち込む工程の前に、各筒状部内に前記コンクリート、モルタル、セメント、又は、アスファルトが侵入することを防止するための第１の蓋部材を各筒状部に取り付ける工程と、前記コンクリート、モルタル、セメント、又は、アスファルトを打ち込む工程の後に、各筒状部に取り付けられた前記第１の蓋部材を取り外す工程と、を更に備えたことが好ましい。 Further, before the step of driving the concrete, mortar, cement, or asphalt, a first lid member for preventing the concrete, mortar, cement, or asphalt from invading into each tubular portion is provided. It is preferable to further include a step of attaching to the tubular portion and a step of removing the first lid member attached to each tubular portion after the step of driving the concrete, mortar, cement, or asphalt. ..

このような構成によれば、路面に排水路を確実に形成することが可能となる。 With such a configuration, it is possible to surely form a drainage channel on the road surface.

また、前記第１の蓋部材は、前記筒状部の第２の貫通孔に挿入される挿入部と、前記挿入部の上部から上方かつ外側に向けて広がる面取り形成部と、を有していることが好ましい。 Further, the first lid member has an insertion portion inserted into the second through hole of the tubular portion and a chamfer forming portion extending upward and outward from the upper portion of the insertion portion. It is preferable to have.

このような構成によれば、筒状部に隣接する位置に打ち込まれたコンクリート等は、破損しやすい直角ではなく、面取り形成部の形状に沿った（面取りされた）状態で成型されることになり、これにより、筒状部に隣接する位置で成型されたコンクリート等が破損することが抑制される。 According to such a configuration, concrete or the like driven into a position adjacent to the tubular portion is molded in a state of being chamfered along the shape of the chamfered forming portion, not at a right angle which is easily damaged. As a result, it is possible to prevent the concrete or the like molded at the position adjacent to the tubular portion from being damaged.

また、各筒状部に取り付けられた前記第１の蓋部材を取り外す工程の後に、前記筒状部の第２の貫通孔に挿入される筒状の挿入部と、前記第２の貫通孔よりも小さな径を有する第３の貫通孔が形成された天面部と、を有する第２の蓋部材を各筒状部に取り付ける工程を更に備えたことが好ましい。 Further, from the tubular insertion portion inserted into the second through hole of the tubular portion and the second through hole after the step of removing the first lid member attached to each tubular portion. It is also preferable to further include a step of attaching a second lid member having a top surface portion having a third through hole having a small diameter to each tubular portion.

このような構成によれば、地表水以外の物が第２の貫通孔内に落下することが抑制される。 With such a configuration, it is possible to prevent objects other than surface water from falling into the second through hole.

本発明の路面成型補助部材によれば、地表水を適切に排水及び貯水することのできる路面を容易に成型することが可能となる。 According to the road surface molding auxiliary member of the present invention, it is possible to easily mold a road surface capable of appropriately draining and storing surface water.

以下、本発明の実施の形態による路面成型補助部材１及び路面成型方法について、図１－図７を参照して説明する。 Hereinafter, the road surface forming auxiliary member 1 and the road surface forming method according to the embodiment of the present invention will be described with reference to FIGS. 1 to 7.

路面成型補助部材１は、コンクリート、モルタル、セメント、又は、アスファルトによる路面成型時に使用されるものであって、図１及び図２に示すように、本体部２と、複数の筒状部３と、を備えている。以下では、コンクリート、モルタル、セメント、又は、アスファルトを路面成型材料と称す。 The road surface molding auxiliary member 1 is used at the time of road surface molding with concrete, mortar, cement, or asphalt, and as shown in FIGS. 1 and 2, the main body portion 2 and the plurality of tubular portions 3 , Is equipped. Hereinafter, concrete, mortar, cement, or asphalt will be referred to as a road surface molding material.

本体部２は、載置面上に載置されるものであり、図１では、本体部２が、地面Ｘに敷かれた砕石Ｙ（“載置面”に相当）上に載置された例が示されている。本体部２の素材としては、可撓性を有するものが好ましく、樹脂や生分解性プラスチック等が考えられる。但し、路面成型材料としてアスファルトを用いる場合には、耐熱性の素材を用いることが好ましい。 The main body 2 is mounted on a mounting surface, and in FIG. 1, the main body 2 is mounted on a crushed stone Y (corresponding to a “mounting surface”) laid on the ground X. An example is shown. As the material of the main body 2, a flexible material is preferable, and a resin, a biodegradable plastic, or the like can be considered. However, when asphalt is used as the road surface molding material, it is preferable to use a heat-resistant material.

図２に示すように、本体部２は、可撓性を有する素材で形成された複数の連通管２１が網状に配置されたものであり、当該網の複数の網目には、複数の第１の貫通孔２２がそれぞれ形成されている。網状に配置された複数の連通管２１間には空間Ｓが設けられている。 As shown in FIG. 2, the main body 2 is formed by arranging a plurality of communication pipes 21 made of a flexible material in a mesh pattern, and a plurality of first meshes of the mesh are arranged in a mesh pattern. Through holes 22 are formed. A space S is provided between the plurality of communication pipes 21 arranged in a mesh pattern.

本実施の形態では、図２に示すように、複数の連通管２１は、格子形状を有するように配置されており、複数の第１の貫通孔２２は、上下方向（図２におけす紙面方向）に貫通しており、複数の連通管２１全体で、上面２３と下面２４を有する略平板形状（シート形状）を有している。 In the present embodiment, as shown in FIG. 2, the plurality of communication pipes 21 are arranged so as to have a lattice shape, and the plurality of first through holes 22 are arranged in the vertical direction (paper surface in FIG. 2). It penetrates in the direction), and has a substantially flat plate shape (sheet shape) having an upper surface 23 and a lower surface 24 in the entire plurality of communication pipes 21.

また、図１及び図３に示すように、各連通管２１は、下部が開放された凹形状を有している。後述するように、連通管２１と載置面との間には貯水が可能であるが、本実施の形態では、複数の連通管２１全体で１０リットル以上の貯水が可能となるように連通管２１のサイズ、本数等が設定されている。 Further, as shown in FIGS. 1 and 3, each communication pipe 21 has a concave shape with an open lower portion. As will be described later, water can be stored between the communication pipe 21 and the mounting surface, but in the present embodiment, the communication pipe 21 can store 10 liters or more of water as a whole. The size, number, etc. of 21 are set.

本体部２は、図２及び図３に示すように、各連通管２１の下端部から当該連通管２１の外側に向けて略水平方向に延出したリブ部２５を備えている。リブ部２５は、略水平方向に延出しているので、本体部２が載置面（地面Ｘに敷かれた砕石Ｙ）に載置された際に、載置面（地面Ｘに敷かれた砕石Ｙ）に当接することとなる。 As shown in FIGS. 2 and 3, the main body portion 2 includes a rib portion 25 extending substantially horizontally from the lower end portion of each communication pipe 21 toward the outside of the communication pipe 21. Since the rib portion 25 extends substantially in the horizontal direction, when the main body portion 2 is placed on the mounting surface (crushed stone Y laid on the ground X), the rib portion 25 is laid on the mounting surface (ground X). It will come into contact with the crushed stone Y).

また、空間Ｓは、リブ部２５の端部によって画定されることとなる。本実施の形態では、空間Ｓは、上下方向から見て略四角形状に画定されている（図２では、煩雑化を防ぐために中心部にのみリブ部２５を示している）。 Further, the space S will be defined by the end portion of the rib portion 25. In the present embodiment, the space S is defined in a substantially quadrangular shape when viewed from the vertical direction (in FIG. 2, the rib portion 25 is shown only in the central portion in order to prevent complication).

なお、後述するように、本体部２上には、コンクリート、モルタル、セメント、又は、アスファルト等の路面成型材料が打ち込まれるが、これらの路面成型材料は、空間Ｓを介して載置面（地面Ｘに敷かれた砕石Ｙ）と一体に硬化されるので、空間Ｓは、路面成型材料が通過可能なサイズであることが好ましい。 As will be described later, a road surface molding material such as concrete, mortar, cement, or asphalt is driven onto the main body 2, and these road surface molding materials are placed on a mounting surface (ground) via the space S. Since it is hardened integrally with the crushed stone Y) laid on X, it is preferable that the space S has a size that allows the road surface molding material to pass through.

この空間Ｓのサイズは、使用する路面成型材料に応じて設計することが考えられる。例えば、路面成型材料として生コンクリートを使用する場合、生コンクリートに使用する砂利の大きさは、「最大寸法４０ｍｍ」「最大寸法２０ｍｍ(２５ｍｍ)」の２種類に大きく分けられる。４０ｍｍの砂利は、土木工事で多く使用され、２０ｍｍ(２５ｍｍ)の砂利は、建築工事で多く使用される。 The size of this space S may be designed according to the road surface molding material used. For example, when ready-mixed concrete is used as the road surface molding material, the size of the gravel used for the ready-mixed concrete is roughly divided into two types, "maximum dimension 40 mm" and "maximum dimension 20 mm (25 mm)". 40 mm gravel is often used in civil engineering work, and 20 mm (25 mm) gravel is often used in construction work.

従って、生コンクリートを使用する場合には、空間Ｓは、砂利が通過可能なサイズであることが好ましい。例えば、２０ｍｍの砂利を使用し、対向する連通管２１の端部間の距離が４０ｍｍの場合には、図３に示すように、各リブ部２５の延出距離は、１０ｍｍ未満となるように設定することが考えられる。 Therefore, when ready-mixed concrete is used, it is preferable that the space S has a size through which gravel can pass. For example, when 20 mm gravel is used and the distance between the ends of the opposing communication pipes 21 is 40 mm, the extension distance of each rib portion 25 is less than 10 mm as shown in FIG. It is possible to set it.

複数の連通管２１上には鉄筋等の棒状の補強部材を掛け渡して載置可能であり、連通管２１上の補強部材が載置されるべき位置には、補強部材を保持するための保持溝２６が形成されている（図２では、煩雑化を防ぐために一部にのみ保持溝２６を示している）。 A rod-shaped reinforcing member such as a reinforcing bar can be hung and placed on the plurality of communication pipes 21, and the reinforcing member can be held at a position on the communicating pipe 21 where the reinforcing member should be placed. The groove 26 is formed (in FIG. 2, the holding groove 26 is shown only partially in order to prevent complication).

本体部２の端部には、図２に示すように、接続部２７が形成されており、図４に示すように、一の本体部２Ａの端部に形成された接続部２７と他の本体部２Ｂの端部に形成された接続部２７とは、互いに接続可能であり、一の本体部２Ａの連通管２１は、接続部２７同士が接続された際に、他の本体部２Ｂの連通管２１と連通する位置に形成されている。 As shown in FIG. 2, a connection portion 27 is formed at the end portion of the main body portion 2, and as shown in FIG. 4, the connection portion 27 formed at the end portion of one main body portion 2A and another connection portion 27 are formed. The connection portion 27 formed at the end of the main body portion 2B can be connected to each other, and the communication pipe 21 of one main body portion 2A can be connected to the other main body portion 2B when the connection portions 27 are connected to each other. It is formed at a position where it communicates with the communication pipe 21.

接続部２７は、本体部２の各辺に設けられ、四方に所望の数だけ他の本体部２（路面成型補助部材１）と接続可能であることが好ましい。接続部２７の接続方式としては、様々なものが考えらえるが、後述する不陸にも対応可能なように、接続部２７は、本体部２同士が接続された際に多少の遊びを有するように設計されていることが好ましい。 It is preferable that the connecting portions 27 are provided on each side of the main body portion 2 and can be connected to other main body portions 2 (road surface molding auxiliary member 1) in a desired number on all sides. Various connection methods can be considered for the connection unit 27, but the connection unit 27 has some play when the main body units 2 are connected to each other so as to cope with the non-landing described later. It is preferable that it is designed so as to.

複数の筒状部３は、図１及び図２に示すように、複数の第１の貫通孔２２にそれぞれ連通する複数の第２の貫通孔３１を有し、本体部２（上面２３）からそれぞれ突出している。複数の筒状部３は、本体部２が載置面上に載置された状態で上方に向けて突出している。筒状部３の素材としては、本体部２と同様に、可撓性を有するものが好ましく、樹脂や生分解性プラスチック等が考えられる。但し、路面成型材料としてアスファルトを用いる場合には、耐熱性の素材を用いることが好ましい。 As shown in FIGS. 1 and 2, the plurality of tubular portions 3 have a plurality of second through holes 31 communicating with the plurality of first through holes 22, respectively, from the main body portion 2 (upper surface 23). Each is prominent. The plurality of tubular portions 3 project upward with the main body portion 2 mounted on the mounting surface. As the material of the tubular portion 3, a material having flexibility is preferable as in the main body portion 2, and a resin, a biodegradable plastic, or the like can be considered. However, when asphalt is used as the road surface molding material, it is preferable to use a heat-resistant material.

また、上記したように、複数の連通管２１上には鉄筋等の補強部材を掛け渡して載置可能であるが、筒状部３の高さは、補強部材の直径よりも高いことが好ましい。保持溝２６が形成されている場合には、筒状部３の高さは、（補強部材の直径－保持溝２５の深さ）よりも高ければ良い。 Further, as described above, a reinforcing member such as a reinforcing bar can be hung and placed on the plurality of communication pipes 21, but the height of the tubular portion 3 is preferably higher than the diameter of the reinforcing member. .. When the holding groove 26 is formed, the height of the tubular portion 3 may be higher than (diameter of the reinforcing member-depth of the holding groove 25).

上記構成の下、本体部２上の第２の貫通孔３１以外の部分に（図１では、筒状部３の先端付近まで）路面成型材料（図１では、コンクリートＺ）を打ち込むことで、排水路（第２の貫通孔３１及び第１の貫通孔２２）が形成された路面が成型され、路面上の地表水は、この排水路を介して載置面（砕石Ｙ及び地面Ｘ）に排水される。 Under the above configuration, a road surface molding material (concrete Z in FIG. 1) is driven into a portion of the main body 2 other than the second through hole 31 (up to the vicinity of the tip of the tubular portion 3 in FIG. 1). The road surface on which the drainage channel (second through hole 31 and first through hole 22) is formed is molded, and the surface water on the road surface is placed on the mounting surface (crushed stone Y and ground X) through this drainage channel. It is drained.

これにより、路面の下方にある地中に地表水がしみ込むこととなり、地中の水分不足による地盤沈下等の環境問題が生じることが抑制される。また、路面成型補助部材１を用いることで、排水のための水勾配を設ける必要がなくなるので、水平な路面を成型することが可能となる。これにより、地表水が所定の場所に集中して排水されることが防止されるので、河川の氾濫等の環境問題が生じることが抑制されると共に、路面を水平にしたいという要望に応えることも可能となる。 As a result, surface water seeps into the ground below the road surface, and environmental problems such as land subsidence due to lack of water in the ground are suppressed. Further, by using the road surface forming auxiliary member 1, it is not necessary to provide a water gradient for drainage, so that it is possible to form a horizontal road surface. As a result, the surface water is prevented from being drained in a predetermined place, so that environmental problems such as flooding of rivers are suppressed and the demand for leveling the road surface can be met. It will be possible.

また、本実施の形態では、第１の貫通孔２２間が連通管２１により連通されている。これにより、一の第１の貫通孔２２や第２の貫通孔３１が外部からの粉塵等によって目詰まりしたとしても、他の第１の貫通孔２２や第２の貫通孔３１から排水が行われるので、排水機能が損なわれることが抑制される。また、地表水は、連通管２１により本体部２全体及び周囲に分散されるので、地表水を地中に満遍なくしみ込ませることが可能となる。更に、地中の水量が多い場合には、連通管２１と載置面との間に貯水されるので、地中の水量が自動的に調節される。 Further, in the present embodiment, the first through holes 22 are communicated with each other by the communication pipe 21. As a result, even if the first through hole 22 or the second through hole 31 is clogged with dust or the like from the outside, drainage is performed from the other first through hole 22 or the second through hole 31. Therefore, the drainage function is suppressed from being impaired. Further, since the surface water is dispersed in the entire main body 2 and its surroundings by the communication pipe 21, the surface water can be evenly permeated into the ground. Further, when the amount of water in the ground is large, the water is stored between the communication pipe 21 and the mounting surface, so that the amount of water in the ground is automatically adjusted.

ところで、地面Ｘに敷かれた砕石Ｙ等の載置面には、多少なりとも不陸が生じる。そのため、その載置面上に載置された路面成型補助部材１上にコンクリートＺ等が打ち込まれると、本体部２は、不陸により歪んだ状態や負荷が強くかけられた状態で周りをコンクリートＺ等で固められてしまうこととなり、本体部２の強度が低下してしまうおそれがある。 By the way, the surface on which the crushed stone Y or the like laid on the ground X is placed has some unevenness. Therefore, when concrete Z or the like is driven onto the road surface molding auxiliary member 1 mounted on the mounting surface, the main body 2 is surrounded by concrete in a state of being distorted due to non-landing or a state in which a load is strongly applied. It will be hardened by Z or the like, and the strength of the main body 2 may decrease.

しかしながら、本実施の形態では、網状に配置された複数の連通管２１間には空間Ｓが設けられており、この空間Ｓの存在により、可撓性を有する連通管２１は、不陸に応じて容易に撓むことが可能である。従って、不陸の影響により連通管２１の強度が低下し、排水路としての機能が損なわれることが抑制される。更には、各連通管２１は、不陸に応じて容易に変形することのできる下部が開放された凹形状を有しているので、これによっても、連通管２１の強度が低下し、排水路としての機能が損なわれることが抑制される。 However, in the present embodiment, a space S is provided between the plurality of communication pipes 21 arranged in a mesh pattern, and due to the existence of the space S, the flexible communication pipe 21 responds to non-landing. It can be easily bent. Therefore, the strength of the communication pipe 21 is lowered due to the influence of non-landing, and it is suppressed that the function as a drainage channel is impaired. Further, since each communication pipe 21 has a concave shape with an open lower portion that can be easily deformed in response to non-landing, the strength of the communication pipe 21 is also reduced, and the drainage channel is reduced. It is suppressed that the function as is impaired.

一方、上記したように、連通管２１は、下部が開放された凹形状を有しており、連通管２１間には空間Ｓが設けられているため、コンクリート等の路面成型材料が打ち込まれた際に、路面成型材料は空間Ｓから連通管２１内に流れ込んでしまい、排水路としての機能が損なわれてしまうおそれがある。 On the other hand, as described above, the communication pipe 21 has a concave shape with an open lower portion, and a space S is provided between the communication pipes 21, so that a road surface molding material such as concrete is driven into the communication pipe 21. At that time, the road surface molding material may flow into the communication pipe 21 from the space S, and the function as a drainage channel may be impaired.

しかしながら、本実施の形態では、リブ部２５が、各連通管２１の下端部から当該連通管２１の外側に向けて略水平方向に延出しており、このリブ部２５が載置面（地面Ｘに敷かれた砕石Ｙ）に当接するので、路面成型材料が空間Ｓから連通管２１内に流れ込むことが抑制されている。 However, in the present embodiment, the rib portion 25 extends substantially horizontally from the lower end portion of each communication pipe 21 toward the outside of the communication pipe 21, and the rib portion 25 extends from the mounting surface (ground X). Since it comes into contact with the crushed stone Y) laid in the space S, the road surface molding material is suppressed from flowing into the communication pipe 21 from the space S.

なお、路面成型材料は、図５に示すように、筒状部３の第２の貫通孔３１の上端に打設用の第１の蓋部材４が取り付けられた（嵌め込まれた）状態で打ち込まれることが好ましい。 As shown in FIG. 5, the road surface molding material is driven in a state where the first lid member 4 for driving is attached (fitted) to the upper end of the second through hole 31 of the tubular portion 3. Is preferable.

第１の蓋部材４は、図５に示すように、筒状部３の第２の貫通孔３１に挿入される第１の挿入部４１と、第１の挿入部４１の上部から上方かつ外側に向けて広がる面取り形成部４２と、を有している。図５では、第１の挿入部４１は、第２の貫通孔３１と略同一の径を有する円柱形状を有している。また、面取り形成部４２は、円錐台形状を有しており、その上底が第１の挿入部４１の上部に取り付けられた構造を有している。 As shown in FIG. 5, the first lid member 4 has 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. It has a chamfer forming portion 42 that spreads toward the surface. In FIG. 5, the first insertion portion 41 has a cylindrical shape having substantially the same diameter as the second through hole 31. Further, the chamfer forming portion 42 has a truncated cone shape, and has a structure in which the upper bottom thereof is attached to the upper part of the first insertion portion 41.

また、第１の蓋部材４を取り外した後、仕上用の第２の蓋部材５を筒状部３の第２の貫通孔３１に挿入し、その状態で路面の完成とすることが好ましい。 Further, it is preferable that after the first lid member 4 is removed, the second lid member 5 for finishing is inserted into the second through hole 31 of the tubular portion 3 to complete the road surface in that state.

第２の蓋部材５は、図６に示すように、筒状部３の第２の貫通孔３１に挿入される筒状の第２の挿入部５１と、第２の貫通孔３１よりも小さな径を有する第３の貫通孔５２が形成された天面部５３と、を備えている。これにより、地表水以外の物が第２の貫通孔３１内に落下することを抑制しつつ、第３の貫通孔５２及び第２の挿入部５１を介して筒状部３の第２の貫通孔３１内に地表水が流れ込むこととなる。第３の貫通孔５２としては、状況に応じて（ハイヒールを履いた人が多く通る場所、小銭を落としやすい場所等）、適当なサイズ及び形状（網状等）のものを用いれば良い。 As shown in FIG. 6, the second lid member 5 is smaller than the cylindrical second insertion portion 51 inserted into the second through hole 31 of the tubular portion 3 and the second through hole 31. It includes a top surface portion 53 in which a third through hole 52 having a diameter is formed. As a result, while suppressing objects other than surface water from falling into the second through hole 31, the second penetration of the tubular portion 3 through the third through hole 52 and the second insertion portion 51. Surface water will flow into the hole 31. As the third through hole 52, an appropriate size and shape (net-like or the like) may be used depending on the situation (a place where many people wearing high heels pass, a place where coins can be easily dropped, etc.).

続いて、図７のフローチャートを用いて、路面成型補助部材１を用いた路面成型方法について説明する。 Subsequently, a road surface forming method using the road surface forming auxiliary member 1 will be described with reference to the flowchart of FIG. 7.

まず、複数の筒状部３が上方となるように路面成型補助部材１を載置面上に載置する（Ｓ１）。 First, the road surface molding auxiliary member 1 is placed on the mounting surface so that the plurality of tubular portions 3 are on the upper side (S1).

続いて、各筒状部３に第１の蓋部材４を取り付ける（Ｓ２）。 Subsequently, the first lid member 4 is attached to each tubular portion 3 (S2).

続いて、本体部２上の筒状部３の第２の貫通孔３１以外の部分にコンクリート等の路面成型材料を打ち込む（Ｓ３）。この工程では、第１の蓋部材４の面取り形成部４２の全体は埋まらない程度の量の路面成型材料を打ち込むことが好ましい。 Subsequently, a road surface molding material such as concrete is driven into a portion of the tubular portion 3 on the main body portion 2 other than the second through hole 31 (S3). In this step, it is preferable to drive in an amount of the road surface molding material so that the entire chamfer forming portion 42 of the first lid member 4 is not filled.

続いて、各筒状部３に取り付けられた第１の蓋部材４を取り外す（Ｓ４）。なお、第１の蓋部材４は、路面成型材料が完全に硬化していなくても、形状が崩れない程度に硬化していれば、取り外し可能である。 Subsequently, the first lid member 4 attached to each tubular portion 3 is removed (S4). The first lid member 4 can be removed even if the road surface molding material is not completely cured, as long as it is cured to such an extent that the shape does not collapse.

最後に、各筒状部３に第２の蓋部材５を取り付けて（Ｓ５）、路面の完成とする。 Finally, the second lid member 5 is attached to each tubular portion 3 (S5) to complete the road surface.

これにより、筒状部３が路面から突出しない安全性の高い路面が成型されることとなる。 As a result, a highly safe road surface is formed in which the tubular portion 3 does not protrude from the road surface.

なお、第１の蓋部材４の面取り形成部４２は、第１の挿入部４１の上部から上方かつ外側に向けて広がっているので、筒状部３に隣接する位置に打ち込まれたコンクリート等の路面成型材料は、破損しやすい直角ではなく、面取り形成部４２の形状に沿った（面取りされた）状態で成型されることとなり、これにより、仮に第２の蓋部材５を各筒状部３に取り付けなかったとしても、筒状部３に隣接する位置で成型された路面成型材料が破損することが抑制される。 Since the chamfer forming portion 42 of the first lid member 4 extends upward and outward from the upper part of the first insertion portion 41, concrete or the like driven into a position adjacent to the tubular portion 3 may be used. The road surface molding material is molded in a state of being chamfered along the shape of the chamfer forming portion 42, not at a right angle which is easily damaged, whereby the second lid member 5 is tentatively formed into each tubular portion 3. Even if it is not attached to, the road surface molding material molded at the position adjacent to the tubular portion 3 is prevented from being damaged.

以上説明したように、本実施の形態による路面成型補助部材１では、複数の筒状部３が本体部２（網状に配置された複数の連通管２１）に連通していると共に、網状に配置された複数の連通管２１間には空間Ｓが設けられている。 As described above, in the road surface molding auxiliary member 1 according to the present embodiment, the plurality of tubular portions 3 communicate with the main body portion 2 (a plurality of communication pipes 21 arranged in a mesh pattern) and are arranged in a mesh pattern. A space S is provided between the plurality of communication pipes 21.

このような構成によれば、本体部２上の第２の貫通孔３１以外の部分にコンクリート等の路面成型材料を打ち込むことで、筒状部３（第２の貫通孔３１）及び第１の貫通孔２２により排水路が形成された路面が成型され、路面上の地表水は、この排水路を介して載置面に排水される。これにより、路面の下方にある地中に地表水がしみ込むこととなり、地中の水分不足により地盤沈下等の環境問題が生じることが抑制される。この際、空間Ｓの存在により、可撓性を有する本体部２は、不陸に応じて容易に撓むことが可能であるため、不陸の影響により本体部２（特に連通管２１）の強度が低下し、排水路としての機能が損なわれることが抑制される。また、路面成型補助部材１を用いることで、排水のための水勾配を設ける必要がなくなるので、水平な路面を成型することが可能となる。これにより、地表水が所定の場所に集中して排水されることが防止されるので、河川の氾濫等の環境問題が生じることも抑制されると共に、路面を水平にしたいという要望に応えることも可能となる。また、コンクリート等は、本体部２上に打ち込まれるので、本体部２の分までコンクリート等の強度を増加させることができる。従って、本体部２として、厚みの大きいものを採用すれば、より強度を増加させることが可能となる。また、複数の第１の貫通孔２２間が連通管２１により連通されているので、一の第１の貫通孔２２や第２の貫通孔３１が外部からの粉塵等によって目詰まりしたとしても、他の第１の貫通孔２２や第２の貫通孔３１から排水が行われるので、排水機能が損なわれることが抑制される。また、地表水は、連通管２１により本体部２全体に分散されるので、地表水を地中に満遍なくしみ込ませることが可能となる。更に、地中の水量が多い場合には、連通管２１と載置面との間に貯水されるので、地中の水量が自動的に調節される。 According to such a configuration, by driving a road surface molding material such as concrete into a portion other than the second through hole 31 on the main body portion 2, the tubular portion 3 (second through hole 31) and the first through hole 31 can be driven. The road surface on which the drainage channel is formed is formed by the through hole 22, and the surface water on the road surface is drained to the mounting surface through the drainage channel. As a result, surface water seeps into the ground below the road surface, and environmental problems such as land subsidence due to lack of water in the ground are suppressed. At this time, due to the presence of the space S, the flexible main body portion 2 can be easily bent in response to the non-landing, and therefore, due to the influence of the non-landing, the main body portion 2 (particularly the communication pipe 21) The strength is reduced and the function as a drainage channel is suppressed from being impaired. Further, by using the road surface forming auxiliary member 1, it is not necessary to provide a water gradient for drainage, so that it is possible to form a horizontal road surface. As a result, the surface water is prevented from being drained in a predetermined place, so that environmental problems such as flooding of rivers are suppressed and the demand for leveling the road surface can be met. It will be possible. Further, since the concrete or the like is driven onto the main body portion 2, the strength of the concrete or the like can be increased by the amount of the main body portion 2. Therefore, if a thick body portion 2 is used, the strength can be further increased. Further, since the plurality of first through holes 22 are communicated with each other by the communication pipe 21, even if the first through hole 22 or the second through hole 31 is clogged with dust or the like from the outside. Since drainage is performed from the other first through hole 22 and the second through hole 31, it is possible to prevent the drainage function from being impaired. Further, since the surface water is dispersed in the entire main body 2 by the communication pipe 21, the surface water can be evenly permeated into the ground. Further, when the amount of water in the ground is large, the water is stored between the communication pipe 21 and the mounting surface, so that the amount of water in the ground is automatically adjusted.

また、本実施の形態による路面成型補助部材１では、各連通管２１が、下部が開放された凹形状を有している。 Further, in the road surface molding auxiliary member 1 according to the present embodiment, each communication pipe 21 has a concave shape with an open lower portion.

このような構成によれば、下部が開放された凹形状は不陸に応じて容易に変形することができるので、不陸の影響により連通管２１の強度が低下し、排水路としての機能が損なわれることが更に抑制される。 According to such a configuration, the concave shape with the lower part open can be easily deformed in response to the non-landing, so that the strength of the communication pipe 21 is reduced due to the influence of the non-landing, and the function as a drainage channel is reduced. The damage is further suppressed.

また、本実施の形態による路面成型補助部材１では、各連通管２１の下端部から外側に向けて略水平方向に延出したリブ部２５を備えている。 Further, the road surface molding auxiliary member 1 according to the present embodiment includes a rib portion 25 extending substantially horizontally from the lower end portion of each communication pipe 21 to the outside.

このような構成によれば、リブ部２５が載置面（地面Ｘに敷かれた砕石Ｙ）に当接するので、コンクリート等の路面形成材料が空間Ｓから連通管２１内に流れ込むことが抑制される。 According to such a configuration, since the rib portion 25 comes into contact with the mounting surface (crushed stone Y laid on the ground X), the road surface forming material such as concrete is suppressed from flowing into the communication pipe 21 from the space S. Ru.

また、本実施の形態による路面成型補助部材１では、複数の連通管２１上には鉄筋等の棒状の補強部材を掛け渡して載置可能であり、連通管２１上の補強部材が載置されるべき位置には、補強部材を保持するための保持溝２６が形成されている Further, in the road surface molding auxiliary member 1 according to the present embodiment, a rod-shaped reinforcing member such as a reinforcing bar can be hung and placed on the plurality of communication pipes 21, and the reinforcing member on the communication pipe 21 is placed. A holding groove 26 for holding the reinforcing member is formed at the position where it should be.

このような構成によれば、補強部材を載置する位置を測定したり、補強部材を別途固定する労力が不要となる。 With such a configuration, it is not necessary to measure the position where the reinforcing member is placed or to separately fix the reinforcing member.

また、本実施の形態による路面成型補助部材１では、本体部２の端部には、接続部２７が形成されており、一の本体部２Ａに形成された連通管２１は、接続部２７同士が接続された際に、他の本体部２Ｂに形成された連通管２１又は第１の貫通孔２２に連通する位置に形成されている。 Further, in the road surface molding auxiliary member 1 according to the present embodiment, the connection portion 27 is formed at the end of the main body portion 2, and the communication pipes 21 formed in one main body portion 2A are connected to each other. Is formed at a position communicating with the communication pipe 21 formed in the other main body 2B or the first through hole 22 when the is connected.

このような構成によれば、広い範囲に渡って路面成型補助部材１を載置することができるので、多くの地表水を貯水することが可能となると共に、広い範囲に渡って地表水を地中に満遍なくしみ込ませることが可能となる。 According to such a configuration, since the road surface molding auxiliary member 1 can be placed over a wide range, a large amount of surface water can be stored and the surface water can be stored over a wide range. It is possible to soak it evenly inside.

また、本実施の形態による路面成型補助部材１を用いた路面成型方法では、路面成型補助部材１を載置した上で、本体部２上の第２の貫通孔３１以外の部分にコンクリート等の路面形成材料を打ち込む。 Further, in the road surface molding method using the road surface forming auxiliary member 1 according to the present embodiment, after the road surface forming auxiliary member 1 is placed, concrete or the like is placed in a portion other than the second through hole 31 on the main body 2. Drive in the road surface forming material.

このような構成によれば、地表水を適切に排水及び貯水することのできる路面を容易に成型することが可能となる。 With such a configuration, it becomes possible to easily form a road surface capable of appropriately draining and storing surface water.

また、本実施の形態による路面成型補助部材１を用いた路面成型方法では、路面形成材料を打ち込む工程の前に、各筒状部３に第１の蓋部材４を取り付ける。 Further, in the road surface forming method using the road surface forming auxiliary member 1 according to the present embodiment, the first lid member 4 is attached to each tubular portion 3 before the step of driving the road surface forming material.

このような構成によれば、路面に排水路を確実に形成することが可能となる。 With such a configuration, it is possible to surely form a drainage channel on the road surface.

また、本実施の形態による路面成型補助部材１を用いた路面成型方法では、第１の蓋部材４は、第１の挿入部４１の上部から上方かつ外側に向けて広がる面取り形成部４２を有している。 Further, in the road surface molding method using the road surface molding auxiliary member 1 according to the present embodiment, the first lid member 4 has a chamfer forming portion 42 extending upward and outward from the upper portion of the first insertion portion 41. is doing.

このような構成によれば、筒状部３に隣接する位置に打ち込まれたコンクリート等は、破損しやすい直角ではなく、面取り形成部４２の形状に沿った（面取りされた）状態で成型されることになり、これにより、筒状部３に隣接する位置で成型されたコンクリート等が破損することが抑制される。 According to such a configuration, the concrete or the like driven into the position adjacent to the tubular portion 3 is molded in a state of being chamfered along the shape of the chamfer forming portion 42, not at a right angle which is easily damaged. As a result, it is possible to prevent the concrete or the like molded at the position adjacent to the tubular portion 3 from being damaged.

また、本実施の形態による路面成型補助部材１を用いた路面成型方法では、各筒状部３に第１の蓋部材４を取り外す工程の後に、各筒状部３に第２の蓋部材５を取り付ける。 Further, in the road surface forming method using the road surface forming auxiliary member 1 according to the present embodiment, after the step of removing the first lid member 4 from each cylindrical portion 3, the second lid member 5 is attached to each tubular portion 3. To install.

このような構成によれば、地表水以外の物が第２の貫通孔内に落下することが抑制される。 With such a configuration, it is possible to prevent objects other than surface water from falling into the second through hole.

尚、本発明の路面成型補助部材、及び、路面成型方法は、上述した実施の形態に限定されず、特許請求の範囲に記載した範囲で種々の変形や改良が可能である。 The road surface molding auxiliary member and the road surface molding method of the present invention are not limited to the above-described embodiments, and various modifications and improvements can be made within the scope described in the claims.

例えば、上記実施の形態では、連通管２１は、矩形の本体部２の辺に平行に延びる格子を形成していたが、斜め等の他の方向に延びる格子を形成しても良い。また、連通管２１は、必ずしも格子を形成する必要もなく、網状であれば様々なパターンで形成することができる。 For example, in the above embodiment, the communication pipe 21 forms a grid extending parallel to the side of the rectangular main body 2, but may form a grid extending in another direction such as diagonally. Further, the communication pipe 21 does not necessarily have to form a grid, and can be formed in various patterns as long as it is in a net shape.

また、上記実施の形態では、鉄筋等の補強部材は、連通管２１と略平行に連通管２１上に載置されたが、連通管２１に対して斜め（約４５度等）に載置しても良い。この場合、補強部材が載置されるべき位置（保持溝２６）が多くなるので、補強部材を、より確実に支持することが可能となる。 Further, in the above embodiment, the reinforcing member such as the reinforcing bar is placed on the communication pipe 21 substantially parallel to the communication pipe 21, but is placed diagonally (about 45 degrees, etc.) with respect to the communication pipe 21. You may. In this case, since the number of positions (holding groove 26) on which the reinforcing member should be placed increases, the reinforcing member can be supported more reliably.

また、上記実施の形態では、連通管２１として、凹状溝を例に説明したが、筒状等の他の構造を用いても良い。筒状の場合には、下部に排水孔が形成されていることが好ましい。 Further, in the above embodiment, the concave groove has been described as an example of the communication pipe 21, but other structures such as a cylinder may be used. In the case of a cylinder, it is preferable that a drain hole is formed at the lower part.

また、上記実施の形態では、本体部２は、地面Ｘに敷かれた砕石Ｙ（“載置面”に相当）上に載置されたが、地面Ｘに直接載置されても良く、この場合には、地面Ｘが“載置面”に相当することとなる。 Further, in the above embodiment, the main body 2 is placed on the crushed stone Y (corresponding to the “mounting surface”) laid on the ground X, but may be placed directly on the ground X. In that case, the ground X corresponds to the “mounting surface”.
