Description

本発明は、トンネルの路側に設けられるコンクリート製等の水路構造体及びトンネル構造に関する。   The present invention relates to a concrete channel structure and a tunnel structure provided on the road side of a tunnel.

従来、雨水、事故で漏れたオイル、事故処理の薬液等を排水するために、トンネルの路側には円形水路が設けられているが、円形水路に替わる矩形水路も提案されている。この矩形水路は、図７に示すように、底面部５１と両側の側壁５２、５２と上面部５３とから構成される細長四角筒状の水路構造体５０に設けられ、水路構造体５０の内部が水が流通する矩形水路５４になっている。上面部５３には、内部の矩形水路５４に貫通する路面排水取入用の短冊形状の呑口５７が形成され、呑口５７は水路構造体５０の長手方向に互いに離間して所定間隔で配置されている（特許文献１参照）。   Conventionally, in order to drain rainwater, oil leaked in an accident, chemical solution for accident processing, and the like, a circular waterway is provided on the side of the tunnel, but a rectangular waterway that replaces the circular waterway has also been proposed. As shown in FIG. 7, the rectangular water channel is provided in an elongated rectangular tubular water channel structure 50 including a bottom surface portion 51, side walls 52, 52 on both sides, and a top surface portion 53. Is a rectangular water channel 54 through which water flows. In the upper surface portion 53, a strip-shaped throat 57 for taking in road surface drainage that penetrates the rectangular water channel 54 inside is formed, and the throats 57 are spaced apart from each other in the longitudinal direction of the water channel structure 50 at predetermined intervals. (See Patent Document 1).

この矩形水路５４は、同一水量を流す円形水路よりも水路構造体５０の高さを低くすることができるため、トンネルの掘り下げ量、埋め戻し量、コンクリート量を減らすことができ、材料費や工事費を低減することができると共に、トンネル断面の縮小化を図れるというメリットがある。   The rectangular water channel 54 can reduce the height of the water channel structure 50 compared to the circular water channel through which the same amount of water flows, so that the amount of tunnel dug, backfill, and concrete can be reduced. Costs can be reduced and the tunnel cross section can be reduced.

ところで、上記矩形水路５４の水路構造体５０は、上面部５３の強度を確保するために呑口５７を連続させずに断続的に設ける必要があるが、この構造では、万一の火災時等にガソリン等の危険な液体の漏洩を呑口で連続的に処理することができず、呑口５７と呑口５７との間に危険な液体が溜まって周囲に拡散する可能性がある。そのため、危険な液体を連続的に処理して周囲に拡散することを防止でき、経済性と安全性の両面を達成できる水路構造が求められている。   By the way, the water channel structure 50 of the rectangular water channel 54 needs to be provided intermittently in order to ensure the strength of the upper surface portion 53 without the throat 57 being continuous, but in this structure, in the event of a fire, etc. Leakage of dangerous liquids such as gasoline cannot be continuously processed at the shed, and dangerous liquid may accumulate between the sheds 57 and 57 and diffuse around. Therefore, there is a need for a water channel structure that can prevent dangerous liquids from being continuously processed and diffused to the surroundings and achieve both economic efficiency and safety.

本発明は上記課題に鑑み提案するものであって、トンネル内に漏出した危険な液体を連続的に処理して周囲に拡散することを防止することが可能であり、経済性と安全性の両面を達成できるトンネルの水路構造体及びトンネル構造を提供することを目的とする。   The present invention is proposed in view of the above-mentioned problems, and it is possible to prevent the dangerous liquid leaking into the tunnel from being continuously processed and diffused to the surroundings. It is an object to provide a tunnel waterway structure and a tunnel structure that can achieve the above.

前記構成では、矩形水路の延びる方向に連続する連続溝に液体を線状に排水して一旦溜めてから流すことができるので、火災時等にトンネル内に漏出した危険な液体を連続溝に溜めて連続的に処理し、周囲に拡散することを防止することができる。従って、矩形水路による経済性と安全性の両面を達成することができる。また、連続溝の下側部分で上面部は連結されているので、上面部及び水路構造体の必要強度を確保することができる。 The tunnel water channel structure of the present invention is a tunnel water channel structure provided on the road side of a tunnel, having a rectangular cylindrical shape composed of a bottom surface, side walls on both sides, and a top surface, and having a rectangular water channel inside. The upper surface portion is provided with a bottomed continuous groove extending continuously in a direction in which the rectangular water channel extends, and a pierced hole penetrating the rectangular water channel is spaced apart in a direction in which the continuous groove extends in the continuous groove. It is characterized by being formed at intervals.
In the above configuration, the liquid can be drained linearly into a continuous groove that extends in the direction of the rectangular water channel, and once stored, it can be flown, so that dangerous liquid that leaks into the tunnel during a fire or the like is stored in the continuous groove. Can be processed continuously to prevent diffusion to the surroundings. Accordingly, both economic efficiency and safety due to the rectangular channel can be achieved. Moreover, since the upper surface part is connected with the lower part of the continuous groove, the required strength of the upper surface part and the water channel structure can be ensured.

本発明のトンネルの水路構造体は、前記連続溝が蛇行して設けられることを特徴とする。
前記構成では、渋滞時等に水路構造体上を二輪車が万一走行した場合に対応し、二輪車の安全性を確保することができる。即ち、二輪車は走行特性上、走行方向に直線状に延伸する溝があると前後輪のうち何れか一方がずれてスリップし、バランスを崩して危険であるが、この危険を回避することができる。 The tunnel channel structure according to the present invention is characterized in that the continuous groove is provided in a meandering manner.
With the above configuration, it is possible to ensure the safety of the two-wheeled vehicle in response to a case where the two-wheeled vehicle runs on the water channel structure during traffic congestion or the like. In other words, if a motorcycle has a groove extending linearly in the running direction due to running characteristics, one of the front and rear wheels slips and slips, causing a risk of loss of balance, but this danger can be avoided. .

本発明のトンネルの水路構造体は、前記連続溝の幅が５ｃｍ以上６ｃｍ以下、深さが５ｃｍ以上とされると共に、前記連続溝の下側の架橋部の内部に補強鉄筋が配置されることを特徴とする。
前記構成では、連続溝の幅を５ｃｍ以上、深さを５ｃｍ以上とすることにより、トンネル内に危険な液体が漏出した場合等に、その液体を確実に連続溝に線状排水して連続的に処理し、周囲に拡散することをより確実に防止することができると共に、連続溝の幅を６ｃｍ以下とすることにより、二輪車等の車輪が溝内に脱落するのを防止することができる。また、連続溝の下側の架橋部の内部に補強鉄筋が配置されることにより、水路構造体の必要強度をより確実に確保することができる。 In the waterway structure of a tunnel according to the present invention, the width of the continuous groove is 5 cm or more and 6 cm or less and the depth is 5 cm or more, and a reinforcing bar is disposed inside the bridge portion on the lower side of the continuous groove. It is characterized by.

In addition, it is possible to prevent the wheel from being dropped into the groove by making the width of the continuous groove 6 cm or less. Moreover, the required intensity | strength of a water channel structure can be ensured more reliably by arrange | positioning a reinforcing bar inside the bridge | crosslinking part of the lower side of a continuous groove.

本発明のトンネル構造は、底面部と両側の側壁と上面部とから構成される四角筒状で内部に矩形水路を有し、前記上面部に、前記矩形水路の延びる方向に連続して延びる有底の連続溝が設けられ、前記上面部の表面が両側の側壁から連続溝に向けて下がる方向の傾斜形状に形成され、前記連続溝に、前記矩形水路に貫通する呑口が前記連続溝の延びる方向に離間して所定間隔で形成されるトンネルの水路構造体が、トンネルの路側に設けられることを特徴とする。
前記構成では、トンネルの水路構造体が、通常道路トンネルの路面に形成される道路中心から側壁に向けて下がる方向の傾斜に対応した傾斜形状の表面に形成されているため、矩形水路の延びる方向に連続する連続溝に液体を迅速に導水することができるので、火災時等にトンネル内に漏出した危険な液体を道路に滞留させずに連続溝に速やかに排水して連続的に処理し、周囲に拡散することを防止することができる。従って、矩形水路による経済性と安全性の両面を達成することができる。また、連続溝の下側部分で上面部は連結されているので、上面部及び水路構造体の必要強度を確保することができる。 The tunnel structure of the present invention has a rectangular tube shape composed of a bottom surface portion, side walls on both sides, and an upper surface portion, and has a rectangular water channel therein, and the upper surface portion continuously extends in the extending direction of the rectangular water channel. A continuous groove at the bottom is provided, and the surface of the upper surface portion is formed in an inclined shape in a direction downward from the side walls on both sides toward the continuous groove, and a pier that extends through the rectangular water channel extends into the continuous groove. A tunnel water channel structure formed at a predetermined interval apart in the direction is provided on the road side of the tunnel.
In the above configuration, the tunnel water channel structure is formed on the surface of the inclined shape corresponding to the inclination in the direction going down from the center of the road toward the side wall, which is usually formed on the road surface of the road tunnel. Since the liquid can be quickly introduced into the continuous groove, the dangerous liquid leaked into the tunnel at the time of a fire etc. can be quickly drained into the continuous groove without stagnation on the road and continuously processed. It is possible to prevent diffusion to the surroundings. Accordingly, both economic efficiency and safety due to the rectangular channel can be achieved. Moreover, since the upper surface part is connected with the lower part of the continuous groove, the required strength of the upper surface part and the water channel structure can be ensured.

本発明のトンネルの水路構造体或いはトンネル構造は、矩形水路の延びる方向に連続する連続溝に液体を線状に排水して一旦溜めてから流すことができるので、火災時等にトンネル内に漏出した危険な液体を連続溝に溜めて連続的に処理し、周囲に拡散することを防止することができる。従って、矩形水路による経済性と安全性の両面を達成することができる。また、連続溝の下側部分で上面部は連結されているので、上面部及び水路構造体の必要強度を確保することができる。   The tunnel channel structure or tunnel structure of the present invention can drain liquid into a continuous groove that continues in the direction in which the rectangular channel extends, and can be stored once and then flowed out. It is possible to prevent the dangerous liquid collected in the continuous groove from being continuously processed and diffused to the surroundings. Accordingly, both economic efficiency and safety due to the rectangular channel can be achieved. Moreover, since the upper surface part is connected with the lower part of the continuous groove, the required strength of the upper surface part and the water channel structure can be ensured.

〔第１実施形態のトンネルの水路構造体及びトンネル構造〕
本発明による第１実施形態のトンネルの水路構造体及びトンネル構造について説明する。図１及び図２は第１実施形態のトンネルの水路構造体を示す図である。 [Tunnel Channel Structure and Tunnel Structure of First Embodiment]
A tunnel structure and tunnel structure according to a first embodiment of the present invention will be described. FIG.1 and FIG.2 is a figure which shows the channel structure of the tunnel of 1st Embodiment.

第１実施形態のトンネルの水路構造体１０は、コンクリート等により予め工場等で生産され、トンネルの路側に設けられるものであり、図１及び図２に示すように、底面部１１と、その両側で立設する側壁１２・１２と、側壁１２・１２の上端間に設けられる上面部１３とから構成される四角筒状であり、その内部には中空の矩形水路１４が内設されている。矩形水路１４は横断面視で略横長矩形状になっている。水路構造体１０内には、矩形水路の延びる方向に延びる主筋２１と、主筋２１に交差し底面部１１、側壁１２・１２、上面部１３を矩形に囲う形のフープ筋２２が、所定間隔で（図示例においては水路延伸方向２００mmごとに）設けられている。上面部１３の表面は、両側の側壁１２・１２から連続溝１５に向けて下がる方向の傾斜形状に形成され、この傾斜は図示例においてはそれぞれ２％勾配（通常の道路に設定される勾配と同等）が設定されている。   The tunnel water channel structure 10 of the first embodiment is produced in advance in a factory or the like with concrete or the like, and is provided on the road side of the tunnel. As shown in FIG. 1 and FIG. Are formed in a rectangular tube shape, and a hollow rectangular water channel 14 is provided in the inside thereof. The rectangular water channel 14 has a substantially horizontally long rectangular shape in a cross sectional view. In the water channel structure 10, a main bar 21 extending in the direction in which the rectangular water channel extends, and a hoop bar 22 that intersects the main bar 21 and surrounds the bottom surface part 11, the side walls 12, 12, and the top surface part 13 in a rectangular shape are arranged at predetermined intervals. (In the illustrated example, it is provided every 200 mm in the direction of extending the water channel). The surface of the upper surface portion 13 is formed in an inclined shape in a direction descending from the side walls 12, 12 on both sides toward the continuous groove 15, and this inclination is 2% in the illustrated example (a gradient set for a normal road) Equivalent) is set.

上面部１３には、矩形水路１４の延びる方向に連続して延び且つ矩形水路１４に沿って線状（本例では直線状）に延びる有底の連続溝１５が設けられ、連続溝１５はトンネルの路側に設置した際に壁際側に寄る様に一方側の側壁１２に寄った位置に形成されている。また、連続溝１５の下側は連続溝１５の両側の上面部１３の部分を架橋する架橋部１６になっている。連続溝１５の幅ｔは５ｃｍ以上６ｃｍ以下、連続溝１５の深さは５ｃｍ以上とし、又、連続溝１５の下側の架橋部１６には補強鉄筋としてフープ筋２２が配置されており、架橋部１６の厚さはフープ筋２２が十分なコンクリートかぶり厚さを確保する厚さとすると好適である。尚、連続溝１５は、水路構造体１０及び矩形水路１４が曲線状に延びる場合には、これに沿って曲線状に形成するとよい。   The upper surface portion 13 is provided with a bottomed continuous groove 15 that continuously extends in the extending direction of the rectangular water channel 14 and extends linearly (in this example, a straight line) along the rectangular water channel 14. When it is installed on the road side, it is formed at a position close to the side wall 12 on one side so as to approach the side of the wall. Further, the lower side of the continuous groove 15 is a bridging portion 16 for bridging the upper surface portion 13 on both sides of the continuous groove 15. The width t of the continuous groove 15 is not less than 5 cm and not more than 6 cm, the depth of the continuous groove 15 is not less than 5 cm, and a hoop bar 22 is disposed as a reinforcing reinforcing bar in the bridge portion 16 below the continuous groove 15. The thickness of the portion 16 is preferably a thickness that ensures the hoop bar 22 has a sufficient concrete cover thickness. In addition, when the water channel structure 10 and the rectangular water channel 14 extend in a curved shape, the continuous groove 15 may be formed in a curved shape along this.

連続溝１５には、矩形水路に貫通する呑口１７が連続溝１５の延びる方向に離間して所定間隔で複数形成され、各呑口１７は架橋部１６に貫通して形成されている。本例の呑口１７は連続溝１５の幅と同幅で矩形に形成されている。呑口１７は、架橋部１６のフープ筋２２のかぶり分のコンクリートを避けた形でそれ以外の部分全てを開口するように形成すると好適である。   In the continuous groove 15, a plurality of ridges 17 penetrating the rectangular water channel are formed at predetermined intervals apart from each other in the extending direction of the continuous groove 15, and each ridge 17 is formed to penetrate the bridging portion 16. The shed 17 of this example is formed in a rectangular shape with the same width as the continuous groove 15. It is preferable that the shed 17 is formed so as to open all other portions in a form avoiding the cover of the hoop reinforcement 22 of the bridge portion 16.

トンネルの水路構造体１０は、例えば図３に示すトンネル１００の路側に設置される。トンネル１００の中央部分は自動車道路１０１になっていると共に、その側壁１０２側に監視員等が歩行する通路１０３が一段高くなるようにして形成されている。そして、自動車道路１０１と通路１０３との間に水路構造体１０が埋め込まれて設けられる。水路構造体１０は、連続溝１５が寄っている側を通路１０３側にして配置され、自動車道路１０１の路面と上面部１３の上面が連続するように設けられると共に、複数の水路構造体１０が矩形水路１４を連続するようにして連設される。また、連続溝１５の側壁１０２側の端縁から上方に立設するようにして段差壁１０４が設けられ、段差壁１０４の上面が通路１０３と略同一面とされている。   The tunnel channel structure 10 is installed on the road side of the tunnel 100 shown in FIG. 3, for example. A central portion of the tunnel 100 is an automobile road 101, and a passage 103 on which a monitor or the like walks is formed on the side wall 102 side so as to be higher by one step. The water channel structure 10 is embedded between the automobile road 101 and the passage 103. The water channel structure 10 is disposed with the side where the continuous groove 15 is approaching the passage 103 side, and is provided so that the road surface of the automobile road 101 and the upper surface of the upper surface portion 13 are continuous, and a plurality of water channel structures 10 are provided. The rectangular water channel 14 is continuously provided so as to be continuous. Further, a stepped wall 104 is provided so as to stand up from an edge on the side wall 102 side of the continuous groove 15, and the upper surface of the stepped wall 104 is substantially flush with the passage 103.

尚、図４に示すように、矩形水路１４の水路構造体１０は、同じ排水量で同じコンクリート巻厚の円形水路６４の水路構造体６０に対し、深さを浅くして必要なトンネル掘下量を小さくし、必要なコンクリート量を少なくすることができる。図４の例では、矩形水路１４の水路構造体１０の深さＤ１は円形水路６４の水路構造体６０の深さＤ２に対して１８％浅くすることができ、又、矩形水路１４の水路構造体１０のコンクリート量は円形水路６４の水路構造体６０に対して１６％少なくすることができる。   In addition, as shown in FIG. 4, the channel structure 10 of the rectangular channel 14 has a shallower depth than the channel structure 60 of the circular channel 64 of the same concrete winding thickness with the same amount of drainage, and the necessary tunnel digging amount. The required amount of concrete can be reduced. In the example of FIG. 4, the depth D1 of the water channel structure 10 of the rectangular water channel 14 can be 18% shallower than the depth D2 of the water channel structure 60 of the circular water channel 64, and the water channel structure of the rectangular water channel 14 The concrete amount of the body 10 can be reduced by 16% with respect to the channel structure 60 of the circular channel 64.

自動車道路１０１は、中央よりも側壁１０２側の端部が低くなるように（通常２％程度の勾配）形成されており、自動車道路１０１の路面の水や漏出した液体等は水路構造体１０の方に流れる。そして、水路構造体１０の上面部１３の表面は、両側の側壁１２・１２から連続溝１５に向けて下がる方向すなわち通常道路トンネルの路面に形成される道路中心から側壁に向けて下がる方向の傾斜に対応した傾斜形状の表面に形成されているため、火災時等にトンネル内に漏出した危険な液体は、道路に滞留することなく連続溝１５に流れ込み、連続溝１５で開口している呑口１７を通って矩形水路１４に入り、円滑に排水されるようになっている。更に、漏出等で一度に大量の液体が路面に生じた場合には、その液体が連続溝１５に線状に流れ込んで一旦溜まり、その後に呑口１７を介して矩形水路１４に流れ込むようになっている。   The automobile road 101 is formed so that the end on the side wall 102 side is lower than the center (usually a gradient of about 2%), and water on the road surface of the automobile road 101, leaked liquid, etc. It flows toward. The surface of the upper surface portion 13 of the water channel structure 10 is inclined in a direction descending from the side walls 12 and 12 on both sides toward the continuous groove 15, that is, a direction descending from the road center formed on the road surface of the normal road tunnel toward the side wall. Therefore, the dangerous liquid leaked into the tunnel during a fire or the like flows into the continuous groove 15 without staying on the road and is opened through the continuous groove 15. It passes through the rectangular water channel 14 and smoothly drains. Furthermore, when a large amount of liquid is generated on the road surface at a time due to leakage or the like, the liquid flows linearly into the continuous groove 15 and temporarily accumulates, and then flows into the rectangular water channel 14 through the mouth 17. Yes.

第１実施形態では、連続溝１５に液体を線状に排水して一旦溜めてから流すことができるので、火災時等にトンネル内に漏出した危険な液体を連続溝１５に溜めて連続的に処理し、周囲に拡散することを防止することができる。また、連続溝１５の下側部分である架橋部１６で上面部１３は連結されているので、断面欠損を間欠的に留めて上面部１３及び水路構造体１０の必要強度を確保することができる。また、連続溝の幅を５ｃｍ以上、深さを５ｃｍ以上とする場合には、トンネル１００内に危険な液体が漏出した場合等に、その液体を確実に連続溝１５に線状排水して連続的に処理し、周囲に拡散することをより確実に防止することができると共に、連続溝１５の幅を６ｃｍ以下、連続溝１５の下側の架橋部の内部に補強鉄筋が配置される場合には、水路構造体１０の必要強度をより確実に確保することができる。   In the first embodiment, since the liquid can be drained linearly in the continuous groove 15 and once stored, it can be flown, so that dangerous liquid leaked into the tunnel during a fire or the like is continuously stored in the continuous groove 15. It can be processed and prevented from spreading around. Moreover, since the upper surface part 13 is connected by the bridge | crosslinking part 16 which is a lower part of the continuous groove | channel 15, a cross-sectional defect | deletion can be intermittently stopped and the required intensity | strength of the upper surface part 13 and the water channel structure 10 can be ensured. . In addition, when the width of the continuous groove is 5 cm or more and the depth is 5 cm or more, when a dangerous liquid leaks into the tunnel 100, the liquid is surely linearly drained into the continuous groove 15 and continuous. When the reinforcing reinforcing bars are disposed inside the bridge portion below the continuous groove 15, the width of the continuous groove 15 is 6 cm or less. Can ensure the required strength of the water channel structure 10 more reliably.
