【産業上の利用分野】[Industrial applications]

本考案は、主に、車道や歩道等の路面に排水用の側溝や横断溝などとして埋設 施工されるU字溝用の鉄筋コンクリート製U形ブロック及びそのU形ブロックを 用いた蓋付きU字溝に関する。 The present invention is mainly a reinforced concrete U-shaped block for a U-shaped groove to be buried as a drainage gutter or a transverse groove on a road surface such as a roadway or a sidewalk, and a U-shaped groove with a lid using the U-shaped block. Regarding

【0002】[0002]

【従来の技術】[Prior art]

一般に、路面の側溝等のU字溝は、鉄筋コンクリート製U形ブロック(以下単 にU形ブロックと略称する)を路面に多数連続して埋設することで構成されてい る。このU形ブロックは現場に応じ選択使用できるように各種サイズのものがあ るが、いずれもJIS規格(A5305)で定められている。例えば、溝の幅と 深さが、150mm、180mm、240mm、300mm、360mm、450mmと言っ た各種寸法サイズのものがある。長さは全て600mmである。 Generally, a U-shaped groove such as a side groove on a road surface is constructed by continuously burying a large number of reinforced concrete U-shaped blocks (hereinafter simply referred to as U-shaped blocks) on the road surface. There are various sizes of this U-shaped block that can be selectively used according to the site, but all are specified by JIS standard (A5305). For example, the width and depth of the groove are various sizes such as 150 mm, 180 mm, 240 mm, 300 mm, 360 mm, and 450 mm. All lengths are 600mm.

【0003】 こうした各種サイズのU形ブロックは、上面開放した断面U字形そのものであ って、その上面開放したまま(溝蓋無し)で路面に多数連続して埋設することで U字溝を構成しているのが一般的である。U-shaped blocks of various sizes are U-shaped in cross section with their upper surfaces open, and U-shaped grooves are formed by continuously burying them in the road surface with their upper surfaces open (without a groove lid). It is generally done.

【0004】 しかしながら、上面を開放したままのU字溝では路面を通る歩行者や自転車の 人が落ち怪我をする危険があるので、近年では、グレーチング等の溝蓋を被せる 要望が多い。しかし、一般にU形ブロックは前述の如く単なる断面U字形状であ って、この上部に溝蓋を載架するかたちで受け入れる構造を有していない。この ために、そのU形ブロック上に溝蓋を載せると、その溝蓋が厚さ分だけ路面上に 突出してしまう。その溝蓋の突出を無くすべく、U形ブロックを路面に深く下げ て埋設して溝蓋を路面と面一に納めると、その両側に見切りの様なものが一切無 いので、モルタル等の路面舗装材が押し寄せて来て、該溝蓋が脱着不能となるな どの問題が生じる。However, in the U-shaped groove with the upper surface open, there is a danger that a pedestrian or a bicycle person passing the road surface may fall and be injured. Therefore, in recent years, there is a great demand for covering the groove cover such as grating. However, in general, the U-shaped block has a mere U-shaped cross section as described above, and does not have a structure for receiving the groove lid mounted on the upper portion thereof. For this reason, when the groove lid is placed on the U-shaped block, the groove lid protrudes on the road surface by the thickness. In order to eliminate the protrusion of the groove lid, the U-shaped block is deeply lowered and embedded in the road surface, and the groove lid is flush with the road surface. There are no cutouts on both sides of the groove lid. There is a problem that the pavement material comes over and the groove lid cannot be removed.

【0005】 そこで従来では、U形ブロックを路面と略面一となるように埋設すると共に、 格子状の横長なグレーチングの両側に山形鋼を逆L字状に配して溶接した溝蓋を 用い、この溝蓋を両側の山形鋼の突出片がU形ブロックの両側立上り壁部の上端 面内縁に載るようにして被せるている。こうすることで、モルタル等の路面舗装 材が押し寄せて来ないと共に、路面上への溝蓋の突出高さが両側の山形鋼の突出 片の厚さ(数ミリ)程度に抑えられるている。しかし、この構造では溝蓋にかか る荷重を両側の山形鋼の薄い突出片で支えるので、強度的に弱く、重車両が通る 路面には施工できない事情がある。Therefore, conventionally, a U-shaped block is embedded so as to be substantially flush with the road surface, and a groove lid in which angle steel is arranged in an inverted L shape and welded on both sides of a lattice-shaped horizontally elongated grating is used. The groove lids are covered so that the chevron-shaped projecting pieces on both sides rest on the inner edges of the upper end surfaces of the rising wall portions on both sides of the U-shaped block. By doing this, the road surface pavement material such as mortar does not come in, and the protruding height of the groove lid on the road surface is suppressed to the thickness (several millimeters) of the protruding pieces of angle steel on both sides. However, in this structure, the load on the groove lid is supported by the thin projecting pieces of angle steel on both sides, so the strength is weak and there is a situation where it cannot be installed on the road surface where heavy vehicles pass.

【0006】 このために蓋付きU字溝の場合は、前述のJIS規格(A5305)のU形ブ ロックとは別に、JIS規格(A5345)の鉄筋コンクリート製段付きU形ブ ロックを製作し用いている。これは両側立上り壁部の上端部分を肉厚にし、それ らの内側面にそれぞれ溝蓋の厚さに見合う深さのL字形段部を形成し、この両側 L字形段部に溝蓋を嵌め込むようにして載架する構成である。これであれば厚い 溝蓋を路面上に突出させずに納められて大きな荷重強度が得られる。For this reason, in the case of a U-shaped groove with a lid, a stepped U-shaped block made of reinforced concrete of JIS standard (A5345) is manufactured and used in addition to the U-shaped block of JIS standard (A5305) described above. There is. This is done by thickening the upper ends of the rising walls on both sides, and forming L-shaped steps on each of the inner surfaces to a depth corresponding to the thickness of the groove lid, and fitting the groove lids on these L-shaped steps on both sides. It is configured to be mounted so that it is inserted. If this is the case, a thick groove lid can be stored without protruding onto the road surface, and a large load strength can be obtained.

【0007】[0007]

【考案が解決しようとする課題】[Problems to be solved by the device]

ところで、そうした段付きU形ブロックは、製作するのが面倒でコスト高を招 く。またこの段付きU形ブロックは、車両が通る道路用側溝に使用する目的でつ くられたもので、綺麗に舗装仕上げされることが多い歩道などでは、埋設施工し た状態で溝蓋を嵌めても、その段付きU形ブロックの両側立上り壁部の上端(見 付け部)のコンクリート地肌がそのまま幅広く露出して、周囲路面と馴染まず体 裁が悪い。 By the way, such a stepped U-shaped block is cumbersome to manufacture and costly. This stepped U-shaped block is designed to be used as a gutter for roads on which vehicles pass. For sidewalks that are often neatly paved, the gutter lid should be fitted after being buried. However, the concrete surface of the upper end (finding part) of the rising wall on both sides of the stepped U-shaped block is widely exposed as it is, and the appearance is bad because it is not compatible with the surrounding road surface.

【0008】 そこで、出来ればJIS規格(A5305)で定められた単純構造の鉄筋コン クリート製U形ブロックのようなものを用いて見付け面部が露出しない蓋付きの U字溝を安価に施工したい。しかしながら、この単純構造のU形ブロックを用い ると、前述の如く溝蓋が厚さ分だけ路面上に突出したり、両側からモルタル等の 路面舗装材が押し寄せて溝蓋が脱着不能或いは納まりが悪くなったり、溝蓋の両 側に山形鋼を溶接してU形ブロック上に載架することで充分な荷重強度が得られ なかったりする問題がある。Therefore, if possible, we would like to inexpensively construct a U-shaped groove with a lid whose exposed surface is not exposed by using something like a U-shaped block made of concrete with a simple structure defined by JIS standard (A5305). However, when this U-shaped block with a simple structure is used, the groove lid protrudes on the road surface by the thickness as described above, or the road surface paving material such as mortar squeezes from both sides and the groove lid cannot be removed or is difficult to fit. There is a problem that sufficient load strength cannot be obtained by welding angle steel on both sides of the groove lid and mounting it on a U-shaped block.

【0009】 本考案は前記事情に鑑みなされ、その目的とするところは、コンクリート見付 け部が幅広に露出する段付きU形ブロックを使用せずに、従来の単純な鉄筋コン クリート製U形ブロックの成型型枠により簡単に製作できて、蓋無しのU字溝の 施工に用いることが出来るのは勿論のこと、蓋付きU字溝の施工にも従来の問題 を解消して有効に利用できる経済的で施工性の良い鉄筋コンクリート製U形ブロ ックを提供することにある。The present invention has been made in view of the above circumstances, and an object thereof is to use a conventional simple U-shaped concrete reinforcing bar without using a stepped U-shaped block in which a concrete found portion is widely exposed. Not only can it be easily manufactured with a block molding frame and can be used for U-grooves without lids, but it can also be used effectively for the construction of U-grooves with lids, eliminating the conventional problems. It is to provide a U-shaped block made of reinforced concrete that is economical and has good workability.

【0010】 また、本考案は、前記考案の鉄筋コンクリート製U形ブロックを用いて、溝蓋 の路面上への突出やモルタル等の路面舗装材の押し寄せがなく、溝蓋の納まりが 良く荷重強度にも優れ、且つスッキリした見切り縁が得られる蓋付きU字溝を安 価に提供することにある。In addition, the present invention uses the U-shaped block made of reinforced concrete of the above-mentioned invention, and there is no protrusion of the groove lid onto the road surface or rushing of road surface paving material such as mortar, so that the groove lid can be stored and the load strength can be improved. It is also to provide a U-shaped groove with a lid that is excellent and provides a clean parting edge at low cost.

【課題を解決するための手段】[Means for Solving the Problems]

本考案は前記目的を達成するために、路面に多数連続して埋設されることで側 溝等のU字溝を構成する鉄筋コンクリート製U形ブロックにおいて、両側立上り 壁部の少なくとも一箇所にそれぞれ外側方から見切りライナー締結用のボルトが ねじ込み可能な雌ねじアンカーを予め埋め着して設けていることを特徴とする。 In order to achieve the above-mentioned object, the present invention is a reinforced concrete U-shaped block in which a plurality of U-shaped grooves, such as a side groove, are formed by being continuously embedded in a road surface. It is characterized in that a bolt for fastening the parting liner is provided with a female screw anchor into which the screw can be screwed in in advance.

【0012】 本考案の蓋付きU字溝は、前記目的を達成するために、前記考案の鉄筋コンク リート製U形ブロックを路面に多数連続して埋設し、これらU形ブロックの両側 立上り壁部の外側面に、該複数個ずつのU形ブロックに跨がる横長な見切りライ ナーをそれぞれ添設し、これら各見切りライナーの長手方向複数箇所に形成され た縦長なフリーホールを、前記各U形ブロックの両側立上り壁部の雌ねじアンカ ーに外側方からねじ込むボルトに遊嵌すると共に、その各見切りライナーを前記 U形ブロックの両側立上り壁部より上方に略溝蓋の厚さに見合う分だけ延出する 状態に高さ調整して前記各ボルトの締付けにより固定支持し、この両側見切りラ イナーの上方延出部相互間にて溝蓋を前記U形ブロック上に載架して設けたこと を特徴とする。In order to achieve the above-mentioned object, the U-shaped groove with a lid of the present invention has a large number of U-shaped blocks made of reinforced concrete of the above-mentioned device continuously buried in a road surface, and the rising wall portions on both sides of these U-shaped blocks. On the outer surface of each of the U-shaped blocks, laterally long parting liners are installed respectively, and vertical free holes formed at plural positions in the longitudinal direction of each of the parting liners are connected to the U-shaped blocks. While loosely fitting the bolts that are screwed into the female screw anchors on both side rising walls of the U-shaped block from the outside, each parting liner is located above the both rising walls of the U-shaped block by an amount corresponding to the thickness of the groove cover. The height is adjusted to the extended state, the bolts are fixedly supported by tightening the bolts, and the groove lids are mounted on the U-shaped block between the upward extending portions of the parting liners on both sides. To Characterize.

【作用】[Action]

前記構成の鉄筋コンクリート製U形ブロックによれば、路面に多数連続して埋 設されることで従来同様に蓋無しの上面開放した側溝等のU字溝を構成できる。 一方、それらU形ブロックの埋設施工の際に、その各U形ブロックの両側立上り 壁部の雌ねじアンカーに外側方からボルトをねじ込み、それらボルトに縦長なフ リーホールを遊嵌する状態で横長な見切りライナーをU形ブロックの両側立上り 壁部の外側面に、該複数個ずつのU形ブロックに跨がってそれぞれ添設し、これ ら各見切りライナーを前記U形ブロックの両側立上り壁部より上方に略溝蓋の厚 さに見合う分だけ延出する状態に高さ調整して前記各ボルトの締付けにより固定 支持し、この両側見切りライナーの上方延出部相互間にて溝蓋を前記U形ブロッ ク上に載架することで、蓋付きU字溝を施工できるようになる。 According to the U-shaped block made of reinforced concrete having the above-mentioned structure, a plurality of U-shaped grooves, which are continuously buried in the road surface, can form a U-shaped groove such as a side groove having an open upper surface without a lid as in the past. On the other hand, when burying these U-shaped blocks, bolts are screwed into the female screw anchors on both side rising walls of each U-shaped block from the outside, and the vertically long free holes are loosely fitted to these bolts to make them horizontally long. A parting liner is attached to each of the outer surfaces of the rising walls on both sides of the U-shaped block so as to straddle the plurality of U-shaped blocks. The height of the groove cover is adjusted so that the groove cover extends to the extent corresponding to the thickness of the groove cover, and the bolts are fixed and supported by tightening the bolts. By mounting it on the block, it becomes possible to construct a U-shaped groove with a lid.

【0014】 こうした蓋付きU字溝であれば、U形ブロックをこの両側に添設した見切りラ イナーの上端が路面と面一となるように埋設することにより、両側からのモルタ ル等の路面舗装材の押し寄せがなく、U形ブロック上に載架した溝蓋が、路面上 へ突出せず、両側の見切りライナー間に脱着可能に旨く納まるようになる。その 見切りライナーの高さ調整により厚い溝蓋の使用が可能で充分な荷重強度が得ら れるようになる。しかも、その見切りライナーのみが溝蓋の両側に露出するのみ で、スッキリした見切り縁が得られ、綺麗に舗装仕上げされた歩道などの周囲路 面とうまく馴染んで体裁が良くなる。In the case of such a U-shaped groove with a lid, by burying the U-shaped blocks so that the upper ends of the parting liners attached to both sides of the U-shaped block are flush with the road surface, road surfaces such as mortar from both sides There is no pavement material squeezing, and the groove lid mounted on the U-shaped block does not project onto the road surface, and it can be detachably fitted between the parting liners on both sides. By adjusting the height of the parting liner, a thick groove lid can be used and sufficient load strength can be obtained. Moreover, only the parting liner is exposed on both sides of the groove lid, and a clean parting edge is obtained, and it fits nicely with the surrounding pavement and other surrounding road surfaces to improve the appearance.

【実施例】【Example】

以下、本考案の一実施例を図1乃至図3により説明する。図中1は路面Aに多 数連続して埋設されることで側溝等のU字溝を構成する鉄筋コンクリート製U形 ブロックを示す。このU形ブロック1はJIS規格(A5305)で定められた 例えば、溝の幅と深さが240mmで長さが600mmの寸法サイズの断面U字形状 のものである。 An embodiment of the present invention will be described below with reference to FIGS. Reference numeral 1 in the figure shows a U-shaped block made of reinforced concrete, which is embedded in the road surface A in a large number to form U-shaped grooves such as gutters. The U-shaped block 1 has a U-shaped cross section defined by JIS (A5305), for example, the groove width and depth are 240 mm and the length is 600 mm.

【0016】 このU形ブロック1の両側立上り壁部2の上端寄り部にそれぞれ外側方から見 切りライナー締結用のボルト3をねじ込み可能な雌ねじアンカー4が予め埋め着 して設けられている。この雌ねじアンカー4は錆びないようにステンレス製で、 U形ブロック1の両側立上り壁部2の長手方向中間から両端方に4分の1ずつ離 間した2箇所の位置に設けられいる。ここまでの製作は上記JIS規格(A53 05)で定められたU形ブロックの成型型枠を使用して行う。Female screw anchors 4 into which bolts 3 for fastening a parting liner can be screwed in from the outside are provided in advance at the upper end portions of both side rising wall portions 2 of the U-shaped block 1 respectively. The female screw anchor 4 is made of stainless steel so as not to rust, and is provided at two positions separated from the longitudinal middle of the rising wall portions 2 on both sides of the U-shaped block 1 by 1/4 to both ends. The manufacturing up to this point is performed using a U-shaped block molding frame defined by the JIS standard (A5305).

【0017】 この鉄筋コンクリート製U形ブロック1は、これ自体をそのまま路面Aに多数 連続して埋設することで従来同様に蓋無しの上面開放した側溝等のU字溝を構成 できる。The U-shaped block 1 made of reinforced concrete can be continuously buried in the road surface A as it is to form a U-shaped groove such as an open side groove without a lid as in the conventional case.

【0018】 一方、この鉄筋コンクリート製U形ブロック1を用いて構成される蓋付きU字 溝を説明すると、まず、その鉄筋コンクリート製U形ブロック1を路面Aに図3 に示す如く多数連続して埋設する。この際、各U形ブロック1の両側立上り壁部 2の各雌ねじアンカー4に外側方から見切りライナー締結用のステンレス製の六 角ボルト3をそれぞれねじ込んでおく。On the other hand, a U-shaped groove with a lid formed by using the reinforced concrete U-shaped block 1 will be described. First, a large number of the reinforced concrete U-shaped blocks 1 are continuously embedded in the road surface A as shown in FIG. To do. At this time, the hexagonal bolts 3 made of stainless steel for fastening the parting liner are screwed into the female screw anchors 4 of the rising wall portions 2 on both sides of each U-shaped block 1 from the outside.

【0019】 そして、そのU形ブロック1の両側立上り壁部2の外側面に見切りライナー5 をそれぞれ長手方向に連続して添設する。これら見切りライナー5は横長なステ ンレス帯板状で、長さがU形ブロック1の3倍(1800mm)とされ、これら見 切りライナー5が個々に図3に示す如く4個のU形ブロック1…に跨がるように する。Then, the parting liners 5 are continuously provided in the longitudinal direction on the outer surfaces of the both-side rising wall portions 2 of the U-shaped block 1, respectively. These parting liners 5 are laterally long stainless steel strips and are three times as long as the U-shaped block 1 (1800 mm). These parting liners 5 are individually formed into four U-shaped blocks 1 as shown in FIG. Try to straddle ...

【0020】 これら見切りライナー5は、各々長手方向に間隔(前記U形ブロック1の雌ね じアンカー4と同じ間隔)を存した複数箇所にフリーホール5aが形成されてい る。この各フリーホール5aは該見切りライナー5の略下半部に縦長スリット状 に切欠形成されて、前記各U形ブロック1の両側立上り壁部2の雌ねじアンカー 4に外側方からねじ込んだボルト3に上下高さ調整可能に遊嵌する。なお、この フリーホール5aは長穴でも可である。Each of these parting liners 5 has free holes 5 a formed at a plurality of positions spaced in the longitudinal direction (same spacing as the female anchor 4 of the U-shaped block 1). Each free hole 5a is formed in a vertically elongated slit shape in a substantially lower half portion of the parting liner 5, and the bolt 3 screwed from the outside to the female screw anchor 4 on each of the rising walls 2 on both sides of each U-shaped block 1 is formed. It fits loosely so that the vertical height can be adjusted. The free hole 5a may be a long hole.

【0021】 このボルト3に遊嵌した状態で該各見切りライナー5を前記U形ブロック1の 両側立上り壁部2より上方に略溝蓋6の厚さに見合う分だけ延出するように高さ 調整し、そのまま前記各ボルト3を締付けることにより該各見切りライナー5を U形ブロック1の両側立上り壁部2外側綿に固定支持する。In such a state that the parting liners 5 are loosely fitted to the bolts 3, the heights of the parting liners 5 are extended above the both side rising walls 2 of the U-shaped block 1 by an amount corresponding to the thickness of the groove lid 6. The parting liners 5 are fixedly supported on the outer side cottons on both side rising walls 2 of the U-shaped block 1 by adjusting and bolting the bolts 3 as they are.

【0022】 こうして各U形ブロック1の両側に見切りライナー5を取付けた状態で路面A の下地モルタルBの打設及びレンガタイルC等の舗装材を敷設するなどして、見 切りライナー5の上端と面一に路面舗装を行う。In this way, with the parting liners 5 attached to both sides of each U-shaped block 1, by placing the base mortar B on the road surface A and laying a paving material such as a brick tile C, the upper end of the parting liner 5 And the road surface is paved in the same plane.

【0023】 こうした埋設状態の各U形ブロック1の両側立上り壁部2上端に多数の溝蓋6 を敷き並べるように載架することで、その溝蓋6が各U形ブロック1の両外側の 見切りライナー5の上方延出部相互間に路面Aと面一状態で納まって、蓋付きU 字溝が構成される。By placing a large number of groove lids 6 on the upper ends of the upstanding wall portions 2 on both sides of each U-shaped block 1 in such a buried state, the groove lids 6 are placed on both outer sides of each U-shaped block 1. A U-shaped groove with a lid is formed between the upper extension portions of the parting liner 5 so as to be flush with the road surface A.

【0024】 この各溝蓋6は、鋳鉄製などの格子状をなす肉厚の荷重強度大なるグレーチン グで、両側下面部分にゴム板等の弾性を有する緩衝部材7が貼着され、この干渉 部材7を介してU形ブロック1の両側立上り壁部2上端面に安定して着座接合す るようになっている。Each of the groove lids 6 is made of cast iron or the like and has a grid-like thick wall thickness and a large load strength, and elastic cushioning members 7 such as rubber plates are adhered to the lower surface portions on both sides to prevent interference. The U-shaped block 1 is stably seated and joined to the upper end surfaces of the upstanding wall portions 2 on both sides via the member 7.

【0025】 こうした蓋付きU字溝であれば、U形ブロック1の両側に添設した見切りライ ナー5の上端並びに溝蓋6上面が路面Aと面一となり、両側からのモルタル等の 路面舗装材の押し寄せがなく、U形ブロック1上に載架した溝蓋6が、路面上へ 突出せず、両側の見切りライナー5間に脱着可能に旨く納まるようになる。In the case of such a U-shaped groove with a lid, the upper ends of the parting liners 5 provided on both sides of the U-shaped block 1 and the upper surface of the groove lid 6 are flush with the road surface A, and road pavement such as mortar from both sides is paved. Since there is no pushing of the material, the groove lid 6 mounted on the U-shaped block 1 does not project to the road surface, and can be detachably fitted between the parting liners 5 on both sides.

【0026】 しかも、その薄い見切りライナー5の上端面みが溝蓋6の両側に長手方向に亘 って露出するのみで、スッキリした見切り縁が得られ、綺麗に舗装仕上げされた 歩道などの周囲路面とうまく馴染んで体裁が良くなる。Moreover, only the upper end surface of the thin parting liner 5 is exposed on both sides of the groove lid 6 in the longitudinal direction, and a clear parting edge is obtained, and the surroundings of a pavement that is neatly paved. It blends well with the road surface and improves the appearance.

【0027】 図4及び図5はこの考案の他の実施例を示すもので、ここでは一層大きな荷重 強度が得られるように、厚い溝蓋16を用いている。この場合、見切りライナー 5を該溝蓋16の厚さに見合って高さ調整して施工する。なお、その見切りライ ナー5の上方延出高さが大きく必要で高さ調整しきれない場合には、幅広な見切 りライナーを用いる。また、この実施例では、ゴム板等の弾性を有する緩衝部材 7をU形ブロック1の両側立上り壁部2上端面にアンカーボルト8により取付け ている。なお図中Dは路面Aに舗装材として敷設された擬石である。その他の構 成は前記図1乃至図3のものと同様である。 こうした実施例の蓋付きU字溝においても前記実施例と同様の作用効果が得ら れ、更に高い荷重強度が得られる。FIGS. 4 and 5 show another embodiment of the present invention, in which a thick groove lid 16 is used so as to obtain a larger load strength. In this case, the parting liner 5 is adjusted in height according to the thickness of the groove lid 16 and then constructed. If the height of the parting liner 5 extending upward is large and the height cannot be adjusted, a wide parting liner is used. Further, in this embodiment, a cushioning member 7 having elasticity such as a rubber plate is attached to the upper end surfaces of both side rising walls 2 of the U-shaped block 1 by anchor bolts 8. In the figure, D is a pseudo stone laid as a paving material on the road surface A. Other configurations are the same as those in FIGS. 1 to 3 described above. Even in the U-shaped groove with a lid of such an embodiment, the same operational effect as that of the above-mentioned embodiment can be obtained, and a higher load strength can be obtained.

【考案の効果】[Effect of device]

本考案の鉄筋コンクリート製U形ブロックは、前述の如く構成したので、単純 構造の安価なものでありながら、蓋無しのU字溝の施工に用いることが出来るの は勿論のこと、蓋付きU字溝の施工にも従来の如き溝蓋の路面上への突出やモル タル等の路面舗装材の押し寄せなどの問題を解消できて有効に利用できる。 Since the reinforced concrete U-shaped block of the present invention is constructed as described above, it has a simple structure and is inexpensive, but of course it can be used for the construction of a U-shaped groove without a lid and a U-shaped block with a lid. Even in the construction of the ditch, problems such as the protrusion of the ditch lid onto the road surface and the rushing of road surface paving materials such as mortar as in the past can be solved and effectively used.

【0029】 また、本考案の蓋付きU字溝は、前記考案の鉄筋コンクリート製U形ブロック を用いて、その両外側に見切りラインを高さ調整可能に取り付けることで、荷重 強度の大なる溝蓋が路面上へ突出したり、両側からのモルタル等の路面舗装材の 押し寄せがなく、溝蓋の脱着並びに納まりが良く荷重強度にも優れ、且つスッキ リした見切り縁が得られる。Further, the U-shaped groove with a lid of the present invention is a groove lid with a large load strength by using the reinforced concrete U-shaped block of the above-mentioned invention and attaching the parting lines on both outsides thereof so that the height can be adjusted. There is no protrusion on the road surface or rushing of road surface paving materials such as mortar from both sides, the groove lid is easily attached and removed, the load strength is excellent, and a clean cut edge is obtained.
