Description
分離柵や車線分離標は、道路の側縁から幅方向に所定の間隔をあけて設置されている。そして、分離柵や車線分離標を挟んで一方側が例えば歩行者通行帯となり、他方側が自転車通行帯となる。 In order to ensure the safety of pedestrian walking and bicycle travel, roads are structurally separated into a pedestrian zone and a bicycle zone. In some cases, a road is separated into a bicycle lane and a car lane for the purpose of ensuring the safety of traveling between the bicycle and the vehicle. In order to separate the traffic zone in this way, conventionally, a method of installing a separation fence or a lane separator on the road has been proposed (see, for example, Patent Document 1 and Patent Document 2).
Separation fences and lane markings are installed at predetermined intervals in the width direction from the side edges of the road. And one side becomes a pedestrian traffic zone, for example, and the other side becomes a bicycle traffic zone on both sides of a separation fence or a lane separator.
また、災害発生等の緊急時に、前記分離柵等によって自動車通行帯と分離した自転車通行帯を、緊急自動車用の通行帯に変更する必要がある場合、やはり、分離柵等を撤去する作業が困難となる。このように、従来の構造では、通行帯の改変に容易に対応することができないという問題があった。 In order to install the separation fence and lane separator on the road, the lower part of the pillar and lane separator that the separation fence has is fixed to the ground. For example, in the case of the separation fence, the lower part of the support column of the separation fence is embedded in the ground, and in the case of the lane separation mark as shown in Patent Document 2, it is fixed to the ground by an anchor. However, construction of pedestrian traffic zones separated by separation fences and lane markings will be required later, and when turning around to bypass pedestrian traffic zones, separation fences and lane separation signs fixed to the ground will be temporarily The removal work becomes difficult.
Also, in the event of an emergency such as a disaster, when it is necessary to change the bicycle traffic zone separated from the vehicle traffic zone by the separation fence etc. to the traffic zone for emergency vehicles, it is also difficult to remove the separation fence etc. It becomes. Thus, the conventional structure has a problem that it cannot easily cope with the modification of the traffic zone.
そして、このような排水機能を有する溝ブロックが、通行帯の分離を意図する境界に沿って設けられることで、当該溝ブロックによって、通行帯を分離するための車線分離部材を立設した状態とすることができ、さらに、この車線分離部材を簡単に道路から取り外すことのできる構造が得られる。すなわち、車線分離部材の本体部の下に設けられている固定部は、前記スリットを通過可能な状態(着脱可能状態)と、前記空間部に位置しかつ前記スリットを通過不能な状態(取り付け状態)とに切り替えられるので、前記取り付け状態とすれば、当該固定部は溝ブロックから抜け出ることができず、車線分離部材は溝ブロック上に立設した状態に維持される。そして、前記着脱可能状態とすれば、前記固定部はスリットから抜け出ることができ、車線分離部材を溝ブロックから容易に取り外すことが可能となる。 According to the present invention, for example, rainwater on the road can flow into the drainage groove of the groove block and can flow along the drainage groove, so the groove block is installed on the road. It is used for drainage of the road.
And the groove block which has such a drainage function is provided along the boundary intended to separate the traffic band, and the lane separation member for separating the traffic band is erected by the groove block and Furthermore, a structure in which the lane separation member can be easily removed from the road is obtained. That is, the fixed portion provided below the main body portion of the lane separation member is in a state where it can pass through the slit (detachable state) and in a state where it is located in the space portion and cannot pass through the slit (attached state) ), The fixing portion cannot be removed from the groove block, and the lane separation member is maintained standing on the groove block. And if it is set as the said detachable state, the said fixing | fixed part can come out of a slit, and it becomes possible to remove a lane separation member easily from a groove block.
複数の前記溝ブロックを長手方向に連続して並べて設けた状態で、スリットから清掃用の棒を挿し入れ、清掃棒をスリットに沿って移動させながら排水溝を清掃する場合がある。この場合、隣り合う溝ブロックの端面同士が幅方向に少しずれていると、清掃棒が次の溝ブロックの端面で引っかかるおそれがある。しかし、前記構成によれば、スリットは端面でスリット幅が拡大して開口しているので、清掃棒の引っかかりを抑制することが可能となる。 Moreover, it is preferable that the said slit opens the slit width expanding at the both end surfaces of the longitudinal direction of the said groove block.
In a state where a plurality of the groove blocks are continuously arranged in the longitudinal direction, a draining groove may be cleaned while inserting a cleaning rod through the slit and moving the cleaning rod along the slit. In this case, if the end faces of adjacent groove blocks are slightly shifted in the width direction, the cleaning rod may be caught on the end face of the next groove block. However, according to the above configuration, since the slit is opened with the slit width enlarged at the end surface, it is possible to suppress the cleaning rod from being caught.
この場合、第二面上に蓋部材を設置することができ、排水溝のスリットを隠すことができる。そして、蓋部材は前記段差部とほぼ同じ高さを有しているので、この蓋部材を設置しても、蓋部材の上面と前記第一面とをほぼ同一面に構成ことが可能となる。この結果、蓋部材が設置された溝ブロックは、路面と同一面を形成することが可能となる。 Further, the upper surface of the groove block has a first surface that forms the same surface as the road surface of the road, and a second surface that is formed lower than the first surface and in which the slit is open, and the groove The block preferably has a lid member that has substantially the same height as the step formed between the first surface and the second surface and is placed on the second surface. .
In this case, a lid member can be installed on the second surface, and the slit of the drainage groove can be hidden. Since the lid member has substantially the same height as the stepped portion, even if this lid member is installed, the upper surface of the lid member and the first surface can be configured to be substantially the same plane. . As a result, the groove block provided with the lid member can form the same surface as the road surface.
〔第一の実施の形態〕
図1は、舗装道路10に設置された本発明の道路設備1の実施の一形態を示す斜視図である。舗装道路10は、縁石ブロック15によって車両通行帯11と歩行者通行帯12とが構造的に分離されている。そして、前記車両通行帯11は、本発明の道路設備1によって自転車通行帯14と自動車通行帯13とに構造的に分離されている。
車両通行帯11は、路盤11a上に不透水層11bを敷設すると共に、この不透水層11bの上に透水機能を有する排水層11cを施工することによって構成されている。排水層11cを浸透した雨水は、縁石ブロック15の下方に設けられた集水ブロック17に集水され、集水ブロック17内に形成された水路17aによって排水される。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[First embodiment]
FIG. 1 is a perspective view showing an embodiment of the road equipment 1 of the present invention installed on a paved road 10. In the paved road 10, the vehicle lane 11 and the pedestrian lane 12 are structurally separated by a curb block 15. The vehicle lane 11 is structurally separated into a bicycle lane 14 and an automobile lane 13 by the road facility 1 of the present invention.
The vehicle lane 11 is constructed by laying a water-impermeable layer 11b on the roadbed 11a and constructing a drainage layer 11c having a water-permeable function on the water-impermeable layer 11b. Rainwater that has permeated the drainage layer 11 c is collected in a water collection block 17 provided below the curb block 15 and drained by a water channel 17 a formed in the water collection block 17.
各側溝ブロック2の全体形状は、一方向に長い直方体に形成されている。側溝ブロック2は、車両通行帯11の側縁11dから幅方向に所定の間隔をあけて設置されていて、複数の側溝ブロック2が縦断方向に連続して並んで設置されている。そして、各側溝ブロック2には、排水溝7が形成されている。排水溝7は、車両通行帯11の路面11e上の雨水を排水することができる。つまり、側溝ブロック2は、車両通行帯11の平面集水ドレンとして機能する。図2(a)は側溝ブロック2の斜視図であり、図2(b)(c)は側溝ブロック2の左右側面図である。なお、側溝ブロック2は長手方向に同じ断面形状であり、横断面の輪郭形状は、左側面図の輪郭形状と同じとなる。 The road facility 1 includes a side groove block 2 installed in a vehicle lane 11 and a lane separation member. In the following description, the lane separation member is described as a pole (lane separation mark) 3. The lane separation member may be other than the columnar pole 3 or a wall-shaped member. The side groove block 2 is embedded in the road with the upper surface 4 exposed along the vehicle traveling direction (longitudinal direction) of the vehicle lane 11. In addition, the gutter block 2 is provided along the boundary intended to separate the traffic band.
The overall shape of each side groove block 2 is formed in a rectangular parallelepiped that is long in one direction. The side groove block 2 is installed at a predetermined interval in the width direction from the side edge 11d of the vehicle traffic band 11, and a plurality of side groove blocks 2 are installed side by side in the longitudinal direction. A drain groove 7 is formed in each side groove block 2. The drainage groove 7 can drain rainwater on the road surface 11 e of the vehicle lane 11. That is, the gutter block 2 functions as a flat water collecting drain of the vehicle lane 11. 2A is a perspective view of the side groove block 2, and FIGS. 2B and 2C are left and right side views of the side groove block 2. FIG. Note that the side groove block 2 has the same cross-sectional shape in the longitudinal direction, and the contour shape of the cross section is the same as the contour shape of the left side view.
側溝ブロック2は、コンクリート製であり、排水溝7が形成されているが、前記地先境界ブロックと同等の強度を有している。具体的にはT−25の活荷重に耐えることができる。 In FIG. 2, the gutter block 2 has, for example, the same dimensions (width 150 mm, height 150 mm, length 600 mm) as the ground boundary block (JIS A 5371). The drainage groove 7 formed in the side groove block 2 has a slit 5 opened on the upper surface 4 and a space portion 6 that is continuous with the lower portion of the slit 5 and is expanded inside the side groove block 2. doing. The drain groove 7 is formed continuously from the one end face 8 to the other end face 9 along the longitudinal direction of the side groove block 2.
The side groove block 2 is made of concrete and has a drainage groove 7, but has the same strength as the ground boundary block. Specifically, it can withstand the live load of T-25.
空間部6は、縦長の長円形の断面を有していて、スリット5(の下開口端)よりも特に幅方向に拡大するように形成されている。この実施の形態では、空間部6の幅は70mm、高さは90mmであり、直径φ80の水路と同等(同等以上)の断面積を有している。 The slit 5 opens at the center in the width direction of the upper surface 4, and the slit 5 opens at the space 6. In the embodiment of FIG. 2, the slit 5 is formed so that the slit width increases toward the space 6.
The space 6 has a vertically long oval cross section, and is formed so as to expand more in the width direction than the slit 5 (lower opening end). In this embodiment, the space 6 has a width of 70 mm and a height of 90 mm, and has a cross-sectional area equivalent to (or equivalent to) a water channel having a diameter of φ80.
そして、側溝ブロック2は蓋部材20を有していて、蓋部材20は、前記段差部4cとほぼ同じ厚さ(高さ)を有し、第二面4b上に載せられる。さらに、蓋部材20は、スリット5を含めた左右の第二面4b,4bの合計と同じ幅寸法を有していて、その上面20aは平坦面となっている。 The upper surface 4 of the side groove block 2 of this embodiment is formed with a first surface 4a that forms the same surface as the road surface 11e of the vehicle lane 11 (see FIG. 1) and a lower slit than the first surface 4a. Has a second surface 4b that is open. For this reason, a step 4c is formed on the upper surface 4 of the side groove block 2 between the first surface 4a and the second surface 4b.
The side groove block 2 has a lid member 20, and the lid member 20 has substantially the same thickness (height) as the stepped portion 4c and is placed on the second surface 4b. Further, the lid member 20 has the same width as the total of the left and right second surfaces 4b, 4b including the slit 5, and the upper surface 20a is a flat surface.
このように、側溝ブロック2の上面4のうちの第二面4b上に蓋部材20を設置することで、排水溝7のスリット5を隠すことが可能となる。そして、蓋部材20は段差部4cとほぼ同じ厚さを有しているので、蓋部材20の上面20aと第一面4aとをほぼ同一面にすることが可能となる。この結果、蓋部材20が設置された側溝ブロック2は、車両通行帯11の路面11eと同一面を形成することが可能となり、路面11eに段差が生じることを防止することができる。なお、蓋部材20は、ポール3を使用しない場合であっても、単独で使用することができる。 Further, the lid member 20 can be set to a desired length, and has a length that is installed between the adjacent poles 3 and 3 in FIG. 1, for example (in FIG. 1, the lid member 20 20 is omitted). At this time, it is preferable to partially expose the slit 5 so as to have a water collecting function.
Thus, by installing the lid member 20 on the second surface 4b of the upper surface 4 of the side groove block 2, the slit 5 of the drain groove 7 can be hidden. Since the lid member 20 has substantially the same thickness as the stepped portion 4c, the upper surface 20a and the first surface 4a of the lid member 20 can be made substantially flush with each other. As a result, the side groove block 2 on which the lid member 20 is installed can form the same surface as the road surface 11e of the vehicle traffic belt 11, and can prevent a step from being generated on the road surface 11e. The lid member 20 can be used alone even when the pole 3 is not used.
前記本体部31は、例えば樹脂製であり可撓性を有している。可撓性を有することで、仮に自転車がポール3に衝突しても、衝撃力を和らげることができ安全である。本体部31の高さ寸法Hは、例えば600mm〜700mmである。本体部31はその下部に、下方に拡大しているベース部33を有している。ポール3を側溝ブロック2に固定した状態で、ベース部33の下面板(下面部材)33aが、側溝ブロック2の上面4に当接した状態となる。 The pole 3 has a columnar main body 31 and a fixing portion 32 for fixing the main body 13 to the side groove block 2. The pole 3 has a shaft portion 34 that protrudes downward from the lower surface of the main body portion 31 and has a fixing portion 32 attached to the lower end portion. As a result, the fixing portion 32 is provided below the main body portion 31 of the pole 3.
The main body 31 is made of, for example, resin and has flexibility. By having flexibility, even if a bicycle collides with the pole 3, the impact force can be reduced and it is safe. The height dimension H of the main body 31 is, for example, 600 mm to 700 mm. The main body portion 31 has a base portion 33 that expands downward in the lower portion thereof. In a state where the pole 3 is fixed to the side groove block 2, the lower surface plate (lower surface member) 33 a of the base portion 33 is in contact with the upper surface 4 of the side groove block 2.
図4(a)において、前記軸部34は、下面板33aを挿通していて上下方向に移動可能である。軸部34の上部に止め板35が取り付けられていて、止め板35と下面板33aとの間にバネ36が設けられている。バネ36は、止め板35を下面板33aから引き離す方向に付勢していて、軸部34及び固定部32を引き上げる方向に付勢している。後述するロック機構37によってバネ36は圧縮した状態に維持されている。 FIG. 4 shows the lower part of the pole 3 and the side groove block 2, and is an explanatory view of a method for fixing the pole 3 to the side groove block 2. (a) is a state before fixing, (b) is a state after fixing. Indicates the state.
In FIG. 4A, the shaft portion 34 is inserted through the lower surface plate 33a and is movable in the vertical direction. A stop plate 35 is attached to the upper portion of the shaft portion 34, and a spring 36 is provided between the stop plate 35 and the lower surface plate 33a. The spring 36 urges the stop plate 35 in a direction to pull it away from the lower surface plate 33a, and urges the shaft portion 34 and the fixed portion 32 in a pulling direction. The spring 36 is maintained in a compressed state by a lock mechanism 37 described later.
突出部34aと爪部33bとが係合している状態で、バネ36は圧縮された状態に維持されている。そして、前記のとおり、軸部34及び固定部32を回転方向に拘束した状態で、本体部31を軸線C回りに回転させると、爪部33baから突出部34aは離脱することができる。離脱すると、バネ36の復元力によって、軸部34は軸線C方向の上方(ポール3の上端へ向かう方向)へ移動し、固定部32と下面板33aとは接近した状態となる。 A projecting portion 34 a that projects in the direction perpendicular to the axis is formed in the middle of the shaft portion 34. On the other hand, the lower surface plate 33a is formed with a claw portion 33b that can be engaged with the protruding portion 34a. The shaft part 34 and the fixed part 32 are made of metal. The protrusion 34a and the claw portion 33b constitute the lock mechanism portion 37.
The spring 36 is maintained in a compressed state in a state where the protruding portion 34a and the claw portion 33b are engaged. And as above-mentioned, if the main-body part 31 is rotated around the axis C in the state which restrained the axial part 34 and the fixing | fixed part 32 in the rotation direction, the protrusion part 34a can detach | leave from the nail | claw part 33ba. When detached, the restoring force of the spring 36 causes the shaft portion 34 to move upward in the direction of the axis C (the direction toward the upper end of the pole 3), and the fixed portion 32 and the lower surface plate 33a are brought close to each other.
そして、この側溝ブロック2が、その長手方向を道路の縦断方向として複数連続して道路に設置されているので、これら側溝ブロック2内の排水溝7を道路の排水のために用いることができる。 According to the road facility 1 including the side groove block 2 and the pole 3 as described above, a desired portion where the drainage groove 7 is formed among the plurality of side groove blocks 2 installed in the vehicle lane 11 is provided. The pole 3 can be easily attached. Further, the pole 3 can be temporarily removed, and the operation is simple.
And since this side groove block 2 is continuously installed in the road by making the longitudinal direction into the longitudinal direction of a road, the drainage groove 7 in these side groove blocks 2 can be used for the drainage of a road.
図10は、舗装道路10に設置された本発明の道路設備1の他の実施の形態を示す斜視図である。この舗装道路10は、縁石ブロック15によって歩道側と車両通行帯11とが構造的に分離されている。そして、歩道側は、本発明の道路設備1によって自転車通行帯14と歩行者通行帯12とに構造的に分離されている。
この実施の形態の道路設備1は、前記実施の形態と同様に、側溝ブロック2とポール3とを備えている。そして、側溝ブロック2は、道路の車両走行方向(縦断方向)に沿って上面4が露出した状態で埋設されている。側溝ブロック2の構成は、前記実施の形態と同じである。 [Second Embodiment]
FIG. 10 is a perspective view showing another embodiment of the road equipment 1 of the present invention installed on a paved road 10. In the paved road 10, the sidewalk side and the vehicle lane 11 are structurally separated by a curb block 15. And the sidewalk side is structurally separated into the bicycle traffic zone 14 and the pedestrian traffic zone 12 by the road equipment 1 of the present invention.
The road equipment 1 of this embodiment includes a gutter block 2 and a pole 3 as in the above embodiment. And the gutter block 2 is embed | buried in the state which exposed the upper surface 4 along the vehicle running direction (longitudinal direction) of a road. The configuration of the side groove block 2 is the same as that in the above embodiment.
そして、ポール3の本体部31の下に設けられている固定部32は、側溝ブロック2のスリット5を通過可能な状態(着脱可能状態)と、側溝ブロック2の空間部6に位置しかつスリット5を通過不能な状態(取り付け状態)とに切り替えられるので、前記取り付け状態とすれば、固定部32は側溝ブロック2から抜け出ることができず、ポール3は側溝ブロック2上に立設した状態となることが可能となる。そして、前記着脱可能状態とすれば、前記固定部32はスリット5から抜け出ることができ、ポール3を側溝ブロック2から容易に取り外すことが可能となる。
すなわち、排水機能を有する側溝ブロック2が用いられて、通行帯を分離するためのポール3を立設することができ、さらに、ポール3を簡単に道路から取り外したり、取り付けたりすることができる。 According to the road equipment 1 of each of the embodiments described above, rainwater on the paved road 10 can flow into the space portion 6 through the slit 5 of the side groove block 2 and further flows along the drainage groove 7. Can do. That is, since these gutter blocks 2 are installed on the paved road 10, they are used for drainage of the road. Further, since no running water is present on the surface of the gutter block 2, it is convenient for pedestrians to walk.
And the fixing | fixed part 32 provided under the main-body part 31 of the pole 3 is located in the space part 6 of the side groove block 2, and the state which can pass the slit 5 of the side groove block 2, and a slit. 5 can be switched to a state in which it cannot pass (attached state), so that in the attached state, the fixing portion 32 cannot come out of the side groove block 2, and the pole 3 is erected on the side groove block 2. It becomes possible to become. In the detachable state, the fixing portion 32 can come out of the slit 5 and the pole 3 can be easily detached from the side groove block 2.
That is, the side groove block 2 having a drainage function is used, and the pole 3 for separating the traffic zone can be erected, and the pole 3 can be easily removed from or attached to the road.
また、災害発生等の緊急時において、例えば複数のポール3によって自動車通行帯13と分離した自転車通行帯14を、緊急自動車用の通行帯に変更する必要がある場合であっても、ポール3を撤去する作業は容易となる。このように、本発明の構成によれば、通行帯の改変に容易に対応することができる。 For this reason, for example, the construction of the pedestrian traffic band 12 is required, and even when the pedestrian traffic band 12 is detoured, the work of temporarily removing the pole 3 is easy. And in the state which removed the pole 3, the upper surface 4 of the gutter block 2 and the road surface 11e become flat, and do not become a hindrance of traffic.
Further, in the event of an emergency such as the occurrence of a disaster, even if it is necessary to change the bicycle lane 14 separated from the vehicle lane 13 by the plurality of poles 3 to the lane for emergency vehicles, the pole 3 Removal work is easy. Thus, according to the configuration of the present invention, it is possible to easily cope with alteration of the traffic zone.
さらに、実施の形態の側溝ブロック2の幅寸法は、路面11eに道路管理者によって設けられる区画線の幅と同じである。そこで、この側溝ブロック2の上面4を区画線と同じ色(例えば白や橙)に色彩を施せば、側溝ブロック2は区画線を兼ねることができる。 Further, as described above, the gutter block 2 has the same dimensions as the terrestrial boundary block (JIS A 5371), can be reduced in size, and can have a small construction cross section. And the drainage groove 7 (space part 6) formed in this side groove block 2 has an oval cross section, and although it is not shown in figure, the flow velocity can be raised rather than the block which has a dish-shaped side groove, and scavenging force is made. Can be high. That is, the gutter block 2 can be a “land boundary block that can drain”.
Furthermore, the width dimension of the side groove block 2 of the embodiment is the same as the width of the lane marking provided by the road administrator on the road surface 11e. Therefore, if the upper surface 4 of the side groove block 2 is colored in the same color (for example, white or orange) as the partition line, the side groove block 2 can also serve as the partition line.
図11に示している側溝ブロック2の端面9には、隣り合う他の側溝ブロック2と接続するための嵌め込み部26が形成されている。嵌め込み部26は凹部として形成されていて、この凹部に止水パッキンや目地モルタルが設けられる。
さらに、側溝ブロック2の上面4の端部には、高さが低くなるように形成された切り下げ部27が設けられている。切り下げ部27は、例えば幅が5mm程度であり、上面4の第一面4aから所定寸法(例えば20mm程度)低く形成されている。この切り下げ部27によれば、舗装道路10の路面11e(図1参照)が、側溝ブロック2の上面4よりも沈下しても、切り下げ部27から雨水を集水することができ、路面11eの滞水を抑制することができる。 FIG. 11 shows the side groove block 2 (part 1) according to the first embodiment and the second embodiment, (a) is a plan view, and (b) is a front view. (C) is a bottom view. The front view and the rear view are symmetrical.
A fitting portion 26 for connecting to another adjacent side groove block 2 is formed on the end face 9 of the side groove block 2 shown in FIG. The fitting part 26 is formed as a recess, and a water-stopping packing and joint mortar are provided in the recess.
Furthermore, a cut-down portion 27 is provided at the end of the upper surface 4 of the side groove block 2 so as to be lowered in height. The cut-down portion 27 has a width of about 5 mm, for example, and is formed lower than the first surface 4a of the upper surface 4 by a predetermined dimension (for example, about 20 mm). According to this depressing portion 27, even if the road surface 11e (see FIG. 1) of the paved road 10 sinks below the upper surface 4 of the gutter block 2, rainwater can be collected from the depressing portion 27, and the road surface 11e Stagnating can be suppressed.
そこで、側溝ブロック2の他の形態を以下に示す。 Further, the present invention is not limited to the illustrated form, and may be other forms within the scope of the present invention. For example, the shape of the pole 3 can be changed, and the side groove block 2 has the illustrated side groove. It may have a shape other than the block (part 1).
Therefore, another form of the side groove block 2 is shown below.
図12(a)〜(e)それぞれは、側溝ブロック2の上面4の形状が、図2に示した側溝ブロック2(その1)と異なる形態の断面図である。
図13(f)〜(l)それぞれは、排水溝7の形状が、図2に示した側溝ブロック2(その1)と異なる形態の断面図である。
図14(m)〜(p)それぞれは、排水溝7のスリット5の長手方向の形状が、図2に示した側溝ブロック2(その1)と異なる形態の平面図である。つまり、スリット5は、全長ではなく部分的に設けられている。なお、図14(q)は、図14(m)〜(p)それぞれにおけるV矢視の断面図である。
なお、これら他の形態それぞれの右側面は、図2(c)に準ずる構成とすることができ、嵌め込み部26及び切り下げ部27が形成されていてもよい。又は、これら嵌め込み部26及び切り下げ部27を省略してもよく、この場合、右側面図と左側面図とは同一(又は対称)となる。
さらに、図18(r)〜(t)は、側溝ブロック2の形状が、図2に示した側溝ブロック2(その1)と異なる形態の正面図及び側面図である。この場合、排水層11cを浸透した雨水を、側溝ブロック2側面に形成された溝、穴から排水溝7(空間部6)へ流すことができる。 [Other forms of gutter block 2]
12A to 12E are cross-sectional views in which the shape of the upper surface 4 of the side groove block 2 is different from that of the side groove block 2 (No. 1) shown in FIG.
Each of FIGS. 13F to 13 is a cross-sectional view in which the shape of the drain groove 7 is different from that of the side groove block 2 (part 1) shown in FIG.
14 (m) to 14 (p) are plan views in which the shape of the slit 5 of the drain groove 7 in the longitudinal direction is different from that of the side groove block 2 (part 1) shown in FIG. That is, the slit 5 is provided not partially but partially. In addition, FIG.14 (q) is sectional drawing of V arrow in each of FIG.14 (m)-(p).
In addition, the right side surface of each of these other forms can be configured according to FIG. 2C, and the fitting portion 26 and the cut-down portion 27 may be formed. Alternatively, the fitting portion 26 and the cut-down portion 27 may be omitted, and in this case, the right side view and the left side view are the same (or symmetrical).
18 (r) to 18 (t) are a front view and a side view of a form in which the shape of the side groove block 2 is different from that of the side groove block 2 (No. 1) shown in FIG. In this case, rainwater that has permeated through the drainage layer 11c can flow from the grooves and holes formed on the side surface of the side groove block 2 to the drainage groove 7 (space portion 6).
また、図16(c)に示しているように、側溝桝45には、壁45aの厚さ方向に貫通している溝48が形成されている。この溝48は、側溝ブロック2の排水溝7と同じ断面形状を有している。この溝48が形成されている壁45aに、別の側溝ブロック2(図16(a)において二点鎖線で示している)を接続することができる。なお、側溝桝45は前記溝48が省略されたものであってもよい。 Moreover, the road equipment 1 of the present invention may further include a side groove rod 45 as shown in FIG. 16A in addition to the side groove blocks 2 and the poles 3. The side groove rod 45 is continuously connected to the side groove block 2. As shown in FIG. 16 (b), a groove 46 having a U-shaped cross section is formed in the side groove rod 45. The width dimension of the groove 46 is set to be the same as the width dimension of the space portion 6 of the side groove block 2, and the groove 46 is continuous with the space portion 6. The groove 46 opens upward and is closed by a lid member 47.
Further, as shown in FIG. 16 (c), a groove 48 penetrating in the thickness direction of the wall 45a is formed in the side groove rod 45. The groove 48 has the same cross-sectional shape as the drainage groove 7 of the side groove block 2. Another side groove block 2 (indicated by a two-dot chain line in FIG. 16A) can be connected to the wall 45a in which the groove 48 is formed. The side groove ridge 45 may be one in which the groove 48 is omitted.
また、例えば駐車場等の平面集水用の道路側溝として、図17(c)に示しているように、従来ある皿型側溝50の代わりに、前記側溝ブロック2を設置することができる。この場合、表面に勾配部分や流水が存在しなくなるため、バリアフリー化が可能となる。また、排水溝7によって排水する流速を大きくすることができ、掃流力を大きくすることが可能となる。さらに、施工断面を小さくすることができる。 Further, the side groove block 2 of each of the above embodiments can be a small road side groove as shown in FIG. In this case, the gutter block 2 is installed with its upper surface 4 exposed to the road. Conventionally, the drainage performance is high and the workability is good as compared with the L-shaped side groove block used as a road side groove. Further, in the case of the side groove block having the L-shaped cross section, since rainwater flows on the surface of the block, if the slope 39 for entering the vehicle is installed on the side groove block, the flow of rainwater is obstructed by the slope 39. There is a case. However, according to the side groove block 2 of the present invention, even if the slope 39 is installed on the side groove block 2, it is possible to prevent the rain water from being obstructed by the slope 39.
Further, for example, as shown in FIG. 17C, the side groove block 2 can be installed as a road side groove for flat water collection in a parking lot or the like, instead of the conventional dish-shaped side groove 50. In this case, since there is no gradient portion or running water on the surface, barrier-free operation is possible. Moreover, the flow velocity drained by the drain groove 7 can be increased, and the scavenging force can be increased. Furthermore, the construction cross section can be reduced.
