Description

本発明は、高架道路の床版の遊間の下部において該床版の幅方向に設けられ、道路の融雪水、降雨水や散水などの排水であって床版の接続部間に流れる雨水を排水する簡易排水装置、及び該簡易排水装置を構成する簡易排水部材に関するものである。   The present invention is provided in the width direction of the floor slab in the space between the floor slabs of the elevated road, and drains rainwater flowing between the connecting portions of the floor slab, such as snowmelt water, rainwater, and water spray on the road. The present invention relates to a simple drainage device and a simple drainage member constituting the simple drainage device.

高架橋や高架道路は、通常複数の橋脚や橋台上に支承を解して鋼鉄製の橋桁を設置し、該橋桁の上に鉄筋コンクリート製の床版を形成した構成を有する。床版どうしの接続部は遊間を形成して橋脚ないし橋台の上に設けられ、該遊間部の路面側には一対の櫛の歯状の部材からなる伸縮部材により接続されていて道路の融雪水、降雨水や散水などの排水は伸縮部材の間から橋脚、橋台側に落下するように構成されている。   Viaducts and elevated roads usually have a structure in which a steel bridge girder is installed on a plurality of piers and abutments, and a reinforced concrete floor slab is formed on the bridge girder. The connecting portions of the floor slabs are provided on a bridge pier or an abutment to form a gap, and are connected to the road surface side of the gap portion by a pair of comb-like members, which are melted on the road. In addition, drainage such as rain water and water spray is configured to fall from between the elastic members to the pier and abutment side.

しかるに、上記の高架橋や高架道路の構造では、排水が橋脚、橋桁や支承にかかるため、橋脚を構成するコンクリートの劣化、金属製の橋桁や支承の腐食がこれらに設計時に予測された以上の速さで進行し、特に融雪剤である塩化カルシウムを散布した場合にはさらに早く進行する。道路の管理の経費節減のため、排水を橋脚、橋台、橋桁、支承などの構造材にかからないようにして構造体の長寿命化とメンテナンス低減する目的で、道路の床版の間の下部に排水設備を設ける技術が公知である（特許文献１〜４など）。   However, in the above structures of viaducts and elevated roads, the drainage is applied to the piers, bridge girders and bearings, so the deterioration of the concrete constituting the piers and the corrosion of the metal bridge girders and bearings are faster than those predicted at the time of design. It progresses more quickly, especially when calcium chloride, which is a snow melting agent, is sprayed. In order to reduce the cost of road management, the drainage is drained at the lower part between the floor slabs in order to extend the life of the structure and reduce maintenance by preventing drainage from being applied to structural materials such as piers, abutments, bridge girders and supports. Techniques for providing facilities are known (Patent Documents 1 to 4, etc.).

特許文献１、２に開示の排水装置は、隣接する床版の両端部に固定する樋体を軟質の合成樹脂シートにて形成したものである。   In the drainage devices disclosed in Patent Documents 1 and 2, the casings fixed to both ends of the adjacent floor slabs are formed of a soft synthetic resin sheet.

特許文献３開示の発明は、床版の１方の端面部に樋体を取り付け、床版の他の端面部に該樋体に水を導水する傾斜した補助導水体を取り付けた構成を有する排水装置である。また特許文献４開示の発明は、特許文献１，２と同様に樋体を軟質樹脂シートを樋体として使用し、ワイヤーロープを使用して床版間に固定する技術である。   The invention disclosed in Patent Document 3 is a drainage having a configuration in which a housing is attached to one end surface portion of a floor slab and an inclined auxiliary water guiding body for guiding water to the housing is attached to the other end surface portion of the floor slab. Device. The invention disclosed in Patent Document 4 is a technique of using a flexible resin sheet as a casing and fixing between floor slabs using a wire rope as in Patent Documents 1 and 2.

しかし、特許文献１、２に開示の樋体は、全体が一体成形されたものであるために、道路の幅が異なった場合に、樋体構成材料を該道路幅に合わせて製造しなければならないという問題を有する。特許文献３，４記載の発明では、樋体は連続したものであるために、施工現場への搬送に困難を伴う。また特許文献４記載の発明では、樋体が軟質樹脂シートで構成されており、床版の間隔の変動に追随することが容易であるという利点を有するが、強い風が吹いて樋体が強く揺らされた場合には、流れている水が飛び出してコンクリートの劣化や金属材料の腐食を十分に防止できないという問題を有する。   However, since the casings disclosed in Patent Documents 1 and 2 are integrally formed as a whole, if the width of the road is different, the casing constituting material must be manufactured to match the road width. It has a problem of not becoming. In the inventions described in Patent Documents 3 and 4, since the casing is continuous, it is difficult to transport to the construction site. Further, in the invention described in Patent Document 4, the casing is made of a soft resin sheet, and it has an advantage that it is easy to follow the change in the space between the floor slabs. When shaken, there is a problem that the flowing water jumps out and the deterioration of the concrete and the corrosion of the metal material cannot be sufficiently prevented.

さらに、上記特許文献１〜４記載の排水装置は、いずれも排水路が一体に形成されているために、部分的に損傷が発生した場合でも全体を交換しなければならないという問題を有するものである。   Furthermore, the drainage devices described in Patent Documents 1 to 4 have a problem that all of the drainage channels are integrally formed, and therefore the entire drainage device must be replaced even when partial damage occurs. is there.

さらに特許文献３記載の発明では、樋体は長さ方向に同一断面形状であるために、流水量の増加する下流側でのオーバーフローを防止するためには上流側も含めて全体として深いものとしなければならず、重量の軽減が難しく、かつ取付時に樋体を傾斜させる必要があって施工に問題を有するものである。   Furthermore, in the invention described in Patent Document 3, since the casing has the same cross-sectional shape in the length direction, the entire body including the upstream side is deep in order to prevent overflow on the downstream side where the amount of flowing water increases. Therefore, it is difficult to reduce the weight, and it is necessary to incline the housing at the time of installation, which causes a problem in construction.

図３（ａ）に例示の簡易排水部材Ｐ４は、図２に例示の簡易排水部材と同様の形状を有するものであるが、浅底壁面材ならびに深底壁面材がなく、樋状を有する部材である。図３（ｂ）に例示の簡易排水部材Ｐ５は、図３（ａ）の部材の浅底部側端部に浅底壁面材３９を形成したものであり、図３（ｃ）に例示の簡易排水部材Ｐ６は、図３（ａ）の部材の深底部側端部に深底壁面材３７並びに該深底壁面材３７の下端部に排水口４１を形成したものである。図３（ａ）に例示の簡易排水部材Ｐ４において、浅底壁面材３９と深底壁面材３７の双方とを設け、深底壁面材３７の下端部に排水口４１を設けた簡易排水部材は、図２（ａ）の簡易排水部材Ｐ２となる。広幅部、狭幅部のそれぞれの側面材は平行に構成されていることが好ましい。   The simple drainage member P4 illustrated in FIG. 3 (a) has the same shape as the simple drainage member illustrated in FIG. 2, but does not have a shallow wall surface material or a deep bottom wall material and has a bowl shape. It is. A simple drainage member P5 illustrated in FIG. 3B is obtained by forming a shallow wall material 39 at the shallow bottom side end of the member in FIG. 3A, and the simple drainage illustrated in FIG. 3C. The member P6 is formed by forming a deep bottom wall surface member 37 at a deep bottom side end portion of the member of FIG. 3A and a drain port 41 at a lower end portion of the deep bottom wall surface material 37. In the simple drainage member P4 illustrated in FIG. 3A, the simple drainage member provided with both the shallow wall surface material 39 and the deep wall surface material 37 and provided with the drain port 41 at the lower end of the deep wall surface material 37 is as follows. The simplified drainage member P2 in FIG. The side members of the wide portion and the narrow portion are preferably configured in parallel.

図４に例示の簡易排水部材Ｐ７は、一対の側面材５０と底面部材５４とからなり、底面部材５４は両端部から中央部方向に傾斜して両端部に浅底部５６を、中央部に深底部５８をそれぞれ形成し、深底部５８には下方に排水口５７が形成されている。排水口は中央部の深底部５８の下端部に形成してもよい。側面材５０には、両端部の浅底部５６と中央部の深底部５８の間において段差、好ましくは側面材５０の厚さ程度の段差５５により、両端部側に広幅部５１が、中央部に狭幅部５３が、それぞれ形成されている。図４に例示の簡易排水部材Ｐ７においては、排水口５７は、側面材５０の深底部５８側の端部近傍に側面方向に向いて形成されていてもよい。   The simple drainage member P7 illustrated in FIG. 4 includes a pair of side members 50 and a bottom member 54. The bottom member 54 is inclined from both end portions toward the center portion, with shallow bottom portions 56 at both ends and deep at the center portion. A bottom 58 is formed, and a drain 57 is formed in the deep bottom 58 below. The drain outlet may be formed at the lower end of the deep bottom 58 at the center. The side member 50 is provided with a wide portion 51 at both ends and a central portion with a step 55 between the shallow bottom portion 56 and the central deep portion 58 at both ends, preferably a step 55 having a thickness of about the thickness of the side member 50. Narrow width portions 53 are respectively formed. In the simple drainage member P7 illustrated in FIG. 4, the drainage port 57 may be formed in the vicinity of the end of the side member 50 on the deep bottom 58 side so as to face in the side surface direction.

本発明の簡易排水装置Ｍは、上記の簡易排水部材を単独又は連接使用して構成する。連接する方法を図５に例示した。図５においては、図３（ａ）例示の簡易排水部材Ｐ４を使用した例を斜視図にて示した。２個のＰ２の形状を有する簡易排水部材Ｐｂ，Ｐｃは、簡易排水部材Ｐｂの狭幅部３３ｂを隣接する簡易排水部材Ｐｃの広幅部３１ｃに嵌挿することにより連接する。底面部材４３は上流側の部材が下流側の部材の上に重なるために、底面部材の間からの漏水が起こりにくくなる。嵌挿することにより生じる簡易排水部材どうしの重なり部の間に接着剤ないしシール材を介在させることは好適な態様である。浅底部が最上流側の端部を構成する簡易排水部材Ｐａとしては、浅底部側端部に浅底壁面材３９を形成したものを使用する。排水口は、排水パイプに接続して雨水等を橋脚にかからないように放流ないし貯留する。   The simple drainage device M of the present invention is configured by using the above simple drainage member alone or in combination. The method of connecting is illustrated in FIG. In FIG. 5, the example using the simple drainage member P4 illustrated in FIG. 3A is shown in a perspective view. The simple drainage members Pb and Pc having two P2 shapes are connected by inserting the narrow width portion 33b of the simple drainage member Pb into the wide width portion 31c of the adjacent simple drainage member Pc. In the bottom surface member 43, since the upstream member overlaps the downstream member, water leakage from between the bottom surface members hardly occurs. It is a preferable aspect to interpose an adhesive or a sealing material between the overlapping portions of the simple drainage members generated by the insertion. As the simple drainage member Pa in which the shallow bottom portion constitutes the end portion on the most upstream side, a member in which the shallow wall surface material 39 is formed on the shallow bottom end portion is used. The drainage outlet is connected to a drainage pipe to discharge or store rainwater or the like so as not to reach the pier.

上記構成の簡易排水装置によれば、上端部を水平に形成でき、水量の少ない上流側において溝を浅く形成できるので装置の軽量化が図れ、好ましい。   According to the simple drainage device having the above configuration, the upper end portion can be formed horizontally, and the groove can be formed shallowly on the upstream side where the amount of water is small.

上記図３、図５に示した簡易排水部材においては、段差５５を側面材の厚さの２倍以下、より好ましくは１．５倍以下、さらに好ましくは１．２倍以下に設定することにより、連接部の側面材が面で当接するため連接部の隙間からの漏水を容易に防止することができ、好適である。図１に例示の簡易排水部材Ｐ１を複数使用して簡易排水装置を構成することも可能であり、その場合には、最上流部の簡易排水部材以外は、浅底壁面材１９を裁断除去して使用し、嵌挿する狭幅部と広幅部との間には好ましくはシール材を介在させる。   In the simple drainage member shown in FIG. 3 and FIG. 5 above, by setting the step 55 to 2 times or less, more preferably 1.5 times or less, and even more preferably 1.2 times or less the thickness of the side material. Since the side material of the connecting portion comes into contact with the surface, it is possible to easily prevent water leakage from the gap of the connecting portion, which is preferable. It is also possible to configure a simple drainage device using a plurality of the simple drainage members P1 illustrated in FIG. 1, and in that case, the shallow wall material 19 is cut and removed except for the simple drainage member at the most upstream part. Preferably, a sealing material is interposed between the narrow and wide portions to be used.

浅底部が最上流側の端部を構成する簡易排水部材として、浅底部側端部に浅底壁面材３９を形成したものを使用することにより、簡易排水装置の上流側から橋脚や橋台へ排水が零れ落ちることが防止され、好ましい。   Drain from the upstream side of the simple drainage device to the pier or abutment by using the shallow bottom wall material 39 formed on the shallow bottom side end as a simple drainage member whose shallow bottom constitutes the upstream end Is preferably prevented from falling down.

上記の簡易排水装置Ｍにおいて、上流側に位置する簡易排水部材として、図５においては、の下流側である深底部壁面材のない簡易排水部材（Ｐ４又はＰ５）を使用した例を示したが、深底部壁面材を有する簡易排水部材（Ｐ２又はＰ６）を使用してもよい。   In the simple drainage device M described above, as a simple drainage member located on the upstream side, FIG. 5 shows an example in which a simple drainage member (P4 or P5) without a deep bottom wall surface material on the downstream side is used. A simple drainage member (P2 or P6) having a deep bottom wall surface material may be used.

上記の簡易排水装置Ｍにおいて、流路の長さは連接する簡易排水部材Ｐの数及び簡易排水部材を嵌挿することにより生じる簡易排水部材の広幅部と狭幅部の重なり部の長さを調節することにより行なうことができる。   In the simple drainage device M described above, the length of the flow path is the number of the simple drainage members P connected to each other and the length of the overlapping portion of the wide width portion and the narrow width portion of the simple drainage member generated by inserting the simple drainage member. This can be done by adjusting.

本発明の簡易排水装置Ｍの施工例を、橋脚の中央部において隣接する床版６１ａ，６１ｂの間の遊間Ｄの下方に３個の簡易排水部材Ｐａ，Ｐｂ，Ｐｃを使用して設置する例について図６に例示した。Ｐａは第１簡易排水部材に相当し，Ｐｃは第２簡易排水部材に相当し，Ｐｂは中間簡易排水部材に相当する。使用した簡易排水部材の形状は、Ｐａは図２（ａ）に示したＰ２であり、Ｐｂは図３（ｃ）に示したＰ６であり、Ｐｃは図２（ｂ）に示したＰ３の浅底壁面材３９のないものである。簡易排水部材の連接施工は図５に例示の方法により行なうことができる。   The construction example of the simple drainage device M of the present invention is installed using three simple drainage members Pa, Pb, Pc below the gap D between the adjacent floor slabs 61a, 61b in the center part of the pier. This is illustrated in FIG. Pa corresponds to the first simple drainage member, Pc corresponds to the second simple drainage member, and Pb corresponds to the intermediate simple drainage member. As for the shape of the simple drainage member used, Pa is P2 shown in FIG. 2 (a), Pb is P6 shown in FIG. 3 (c), and Pc is shallow of P3 shown in FIG. 2 (b). The bottom wall material 39 is not provided. The simple drainage member can be connected by the method illustrated in FIG.

簡易排水装置Ｍは、床版６１ａ、６１ｂの遊間下部において、吊金具６３を使用して固定する。吊金具６３（６３ａ，６３ｂ）はＬ字状であり、一端を止めボルトにより床版下面に固定し、他端側を簡易排水部材Ｐａ〜Ｐｃの側面材３０の上部に穿設した取付穴にボルトで固定する。図６の例では、簡易排水部材Ｐは、一方の側面材上部に穿設した取付穴に幅よりも長いボルト６５を使用し、他方の側面材の上部に穿設した穴に該ボルトを挿通して支持することにより装着されている。固定する簡易排水部材Ｐａ，Ｐｂ，Ｐｃは図５に示したような構成にて連接されている。道路幅が狭い場合には第１簡易排水部材であるＰａと第２簡易排水部材であるＰｃを使用し、嵌挿した広幅部と狭幅部の重複を調整することにより施工し、さらに広い場合には、Ｐｂに相当する中間簡易排水部材をさらに介在させることにより床版の幅に応じた施工が可能となる。   The simple drainage device M is fixed using a hanging metal fitting 63 in the lower part of the gap between the floor slabs 61a and 61b. The hanging metal fittings 63 (63a, 63b) are L-shaped, one end is fixed to the lower surface of the floor slab with a stop bolt, and the other end is a mounting hole formed in the upper part of the side member 30 of the simple drainage members Pa to Pc. fix it with bolts. In the example of FIG. 6, the simple drainage member P uses a bolt 65 longer than the width in the mounting hole drilled in the upper part of one side member, and inserts the bolt into the hole drilled in the upper part of the other side member. It is mounted by supporting. The simple drainage members Pa, Pb, and Pc to be fixed are connected in a configuration as shown in FIG. When the road width is narrow, use Pa, which is the first simple drainage member, and Pc, which is the second simple drainage member, and adjust the overlap between the inserted wide and narrow portions. The construction according to the width of the floor slab becomes possible by further interposing an intermediate simple drainage member corresponding to Pb.

図６に例示の簡易排水装置Ｍは、上端が床版に沿って水平に形成されている。従来の技術のように排水部材を樋のように長さ方向に一体に形成して傾斜させて設置すると、下流側では床版下面との間隔が広くなるために強風の場合に床版の遊間を落ちる水が、吹き飛ばされて橋脚にかかる場合があるが、本願発明では、上端が床版に沿って水平に形成されるために、係る問題が起こりにくいという効果が得られる。   The simple drainage device M illustrated in FIG. 6 has an upper end formed horizontally along the floor slab. If the drainage member is integrally formed in the length direction like a gutter and installed in a slanted manner as in the prior art, the space between the bottom surface of the floor slab is widened on the downstream side, so in the case of strong winds, In some cases, the water that falls on the bridge pier is blown off and is applied to the pier. However, in the present invention, since the upper end is formed horizontally along the floor slab, an effect that such a problem hardly occurs is obtained.

図６においては、簡易排水部材Ｐａ，Ｐｂは深底壁面材と該深底壁面材の下端部に横方向に排水口とが形成された構成を有しており、最下流側の簡易排水部材Ｐｃが底面部材の深底部端部近傍に排水口が下方に形成されているが、最下流側の簡易排水部材Ｐｃについても、深底壁面材の下端部に横方向に排水口が形成された構成のものを使用してもよい。係る構成によれば、図６に例示の簡易排水装置Ｍにおいて、Ｐａ，Ｐｂ，Ｐｃを全て図２（ａ）に例示した簡易排水部材Ｐ２を使用し、Ｐｂ，ＰｃにおいてはＰ２の浅底部の浅底壁面材３９を裁断除去して図３（ｃ）のＰ６に相当する形状にして連接して構成することができる。上端は直線状になるように裁断する。裁断した樹脂材料は再利用可能である。   In FIG. 6, the simple drainage members Pa and Pb have a configuration in which a deep bottom wall material and a drain outlet are formed in the lateral direction at the lower end of the deep wall material, and the simplest drainage member on the most downstream side. Pc is formed in the vicinity of the bottom end of the bottom member, and the drain outlet is formed downward. However, the drain outlet is also formed in the lateral direction at the lower end of the bottom wall material for the simple drain member Pc on the most downstream side. You may use the thing of a structure. According to such a configuration, in the simple drainage device M illustrated in FIG. 6, all of Pa, Pb, and Pc use the simple drainage member P2 illustrated in FIG. 2A, and in Pb and Pc, the shallow bottom portion of P2 is used. The shallow wall surface material 39 can be cut and removed to form a shape corresponding to P6 in FIG. The upper end is cut so as to be straight. The cut resin material can be reused.

床版間の遊間が簡易排水装置の幅よりも広い場合には、図６に示したように導水パネルを使用する。導水パネル７１はく字状に折れ曲がった形状であり、一端側が簡易排水装置の遊間内の端部の上部に装着され、上端が傾斜して床版の下方内側に及ぶように設置される。導水パネルの材質は限定されるものではないが、簡易排水部材と同様に熱可塑性樹脂製、ないし傾斜を確実に保持するために裏面を金属板とし、水を受ける上面側に樹脂を積層した積層構造であってもよい。導水パネル７１は簡易排水装置の両上端部に設けてもよい。図６の例では簡易排水部材Ｍの一方の側面材は床版端面と同じ面になっているが、簡易排水部材Ｍの側面材が床版の端面よりも内部側になるように設置してもよい。係る構成にすれば床版端面に沿って落ちる水が橋台や橋脚により確実に降りかからないという効果が得られる。   When the gap between the floor slabs is wider than the width of the simple drainage device, a water guide panel is used as shown in FIG. The water guide panel 71 is bent in a square shape, and is installed so that one end side is attached to the upper part of the end portion in the gap of the simple drainage device, and the upper end is inclined and extends to the lower inner side of the floor slab. The material of the water guide panel is not limited, but it is made of a thermoplastic resin like the simple drainage member, or a laminate in which the back side is a metal plate and the resin is laminated on the upper surface side that receives water in order to securely hold the inclination It may be a structure. The water guide panels 71 may be provided at both upper ends of the simple drainage device. In the example of FIG. 6, one side member of the simple drainage member M is the same surface as the end face of the floor slab, but the side member of the simple drainage member M is installed so as to be inside the end face of the floor slab. Also good. With such a configuration, it is possible to obtain an effect that the water falling along the end face of the slab is not reliably dropped by the abutment or the pier.

図６に例示した簡易排水装置Ｍに使用した簡易排水部材Ｐは、図１〜４例示の簡易排水部材と比較して底面部材が中央部ほど深く形成されている。係る構成により、簡易排水装置の雨水の流れが速くなり、底面の塵，埃の堆積が抑制されるという効果が得られ、好ましい。底面部材の断面形状、即ち側面材と底面部材により構成される溝の底面の形状は、平坦、円弧状、Ｖ字状等、特に限定されるものではないが、上記のように底面の塵，埃の堆積が抑制されるという効果の観点より略浅いＶ字状であることが特に好ましい。   As for the simple drainage member P used for the simple drainage device M illustrated in FIG. 6, the bottom surface member is formed deeper in the center than the simple drainage member illustrated in FIGS. Such a configuration is preferable because the rainwater flow of the simple drainage device is accelerated, and the effect of suppressing dust and dust accumulation on the bottom surface is obtained. The cross-sectional shape of the bottom surface member, that is, the shape of the bottom surface of the groove constituted by the side surface material and the bottom surface member is not particularly limited, such as flat, arc shape, V shape, etc. A substantially shallow V shape is particularly preferable from the viewpoint of the effect of suppressing dust accumulation.

図７にはパラペットを有する橋台上の床版間に設置した例の断面図を示した。この場合、一方の床版はパラペットの側面と略同一面となるために、図６の場合のように床版の下面に吊金具を取り付けることができない。簡易排水部材Ｐは上部に穿設した取付穴を通してアンカーボルトによりパラペットに接して固定されている。簡易排水装置のパラペット接触面と反対面の上部には、図６の場合と同様に導水パネルが装着されている。簡易排水装置のパラペット接触面には、遊間Ｄの床版７１ａ、パラペット７３表面を流れる水が入り込んで、この隙間を通じて橋台に落ちる場合があるので、この漏水を防止するために、例えば、簡易排水装置のパラペット接触面の上端部にシール材ないし接着剤を施工することは好ましい態様である。   FIG. 7 shows a cross-sectional view of an example installed between floor slabs on an abutment having a parapet. In this case, since one floor slab is substantially flush with the side surface of the parapet, the hanging bracket cannot be attached to the lower surface of the floor slab as in the case of FIG. The simple drainage member P is fixed in contact with the parapet with an anchor bolt through an attachment hole drilled in the upper part. A water guide panel is attached to the upper part of the surface opposite to the parapet contact surface of the simple drainage device as in the case of FIG. In order to prevent this water leakage, for example, simple drainage is possible because water flowing on the floor slab 71a of the gap D and the surface of the parapet 73 may enter the parapet contact surface of the simple drainage device and fall into the abutment through this gap. It is a preferable aspect to apply a sealing material or an adhesive to the upper end portion of the parapet contact surface of the apparatus.

さらに幅の広い道路、例えば車線の多い道路、道路の合流地点や分岐地点においては、道路の一端から他端に至る簡易排水装置を施工しようとすると、簡易排水部材の底面部材が傾斜しているために、上端を図６に例示のように床版下面に沿って直線状にすると、排出口を有する最下流側端部の簡易排水部材は深さが非常に深くなり、実用的ではない。このような場合には、複数の簡易排水部材とすることが好ましい。係る例を図８に側面図にて示した。   Furthermore, on wide roads, such as roads with many lanes, road junctions and branching points, when trying to construct a simple drainage device from one end of the road to the other, the bottom member of the simple drainage member is inclined. Therefore, when the upper end is linearly formed along the bottom surface of the floor slab as illustrated in FIG. 6, the depth of the simple drainage member at the most downstream end having the discharge port is not practical. In such a case, it is preferable to use a plurality of simple drainage members. Such an example is shown in a side view in FIG.

図８においては、床版５１の下部幅方向に４個の簡易排水装置Ｍ１〜Ｍ４が設置された例を示した。簡易排水装置Ｍ１，Ｍ２は、両端側を上流、中央部を下流とし、中央部に図４の簡易排水部材Ｐ７を第３簡易排水部材として使用して排水口を形成したものである。簡易排水装置Ｍ３は図６において道路の一端から他端に幅全体に形成したものと同じ構成である。Ｍ４は、図２（ｂ）に例示した簡易排水部材Ｐ３を単独で使用したものである。各簡易排水装置Ｍ１〜Ｍ４の最下流側の簡易排水部材の排水口にはパイプＷ１〜Ｗ４が接続され、排水は該排水パイプを通じて橋脚、橋台にかからないように排出される。   In FIG. 8, the example in which the four simple drainage devices M1-M4 were installed in the lower width direction of the floor slab 51 was shown. The simple drainage devices M1 and M2 are configured such that both ends are upstream, the central portion is downstream, and a drainage port is formed in the central portion using the simple drainage member P7 of FIG. 4 as a third simple drainage member. The simple drainage device M3 has the same configuration as that formed across the entire width from one end to the other end of the road in FIG. M4 uses the simple drainage member P3 illustrated in FIG. 2B alone. Pipes W1 to W4 are connected to drain outlets of the simple drainage members on the most downstream side of the simple drainage devices M1 to M4, and the drainage is discharged through the drainage pipes so as not to reach the pier and the abutment.

上記図８の簡易排水装置において、簡易排水装置Ｍ３は図６に示したものであるが、Ｍ１，Ｍ２は両端側から中央部に傾斜した底面部材を有するもので、最下流側の簡易排水部材は図４に示したＰ７を使用したものである。各構成簡易排水部材の連接は、図５、図６に示したものと同じである。   In the simple drainage device of FIG. 8, the simple drainage device M3 is the one shown in FIG. 6, but M1 and M2 have bottom members inclined from both ends to the center, and the simple drainage member on the most downstream side. Uses P7 shown in FIG. The connection of each simple drainage member is the same as that shown in FIGS.

簡易排水装置Ｍ１〜Ｍ４の間は、漏水防止のためにシール材でシールを行なってもよく、また端部の簡易排水部材の浅底壁面材の上端をカバーしてこの部分に流れ落ちる水を左右の簡易排水装置に導く導水部材を設置してもよい。   Between the simple drainage devices M1 to M4, sealing may be performed with a sealing material to prevent water leakage, and the upper end of the shallow wall material of the simple drainage member at the end is covered and the water flowing into this part is left and right. A water guide member that leads to the simple drainage device may be installed.

簡易排水部材の形状は特に限定されるものではないが、１個の長さが５００〜３０００ｍｍであることが好ましく、８００〜２０００ｍｍであることがより好ましい。底面部材並びに側面材の厚さは２〜１５ｍｍあることが好ましく、３〜１０ｍｍであることがより好ましい。底面部材の傾斜は２〜３０度あることが好ましく、３〜１５度であることがより好ましい。広幅部の間隔は３０〜５００ｍｍあることが好ましく、８０〜３００ｍｍであることがより好ましい。また側面材の高さ、即ち溝の最大深さは、１００〜１７００ｍｍあることが好ましく、１３０〜８００ｍｍであることがより好ましい。   Although the shape of a simple drainage member is not specifically limited, It is preferable that one length is 500-3000 mm, and it is more preferable that it is 800-2000 mm. The thickness of the bottom member and the side member is preferably 2 to 15 mm, and more preferably 3 to 10 mm. The inclination of the bottom member is preferably 2 to 30 degrees, and more preferably 3 to 15 degrees. The interval between the wide portions is preferably 30 to 500 mm, and more preferably 80 to 300 mm. Further, the height of the side member, that is, the maximum depth of the groove is preferably 100 to 1700 mm, and more preferably 130 to 800 mm.
