Description

本発明は、高架鉄道に設けて列車の進行方向を振り分ける分岐器が、列車の持込み雪塊や落下雪によって転換不能の状態になるのを未然に解消するための高架鉄道用分岐器融雪ピットに関する。   The present invention relates to a branching snowmelt pit for an elevated railway for eliminating a situation in which a branching device that is provided in an elevated railway and distributes the traveling direction of a train becomes unconvertible due to a snow lump or falling snow of the train. .
鉄道線路は踏切の廃止や高速化などの諸要請から次第に高架化しており、この鉄道用の高架は、脚柱と、その上部に形成した高架スラブとから大略構成したものからなり、高架スラブ上に路盤コンクリートを打ち、その上に枕木を列設してレールを敷設することによって高架鉄道を形成している。 Railroad tracks are increasingly elevated due to various requests such as the abolition of railroad crossings and higher speeds, and this elevated railway is composed of a pillar and an elevated slab formed on the upper part of the elevated railway slab. Elevated railway is formed by hitting roadbed concrete, laying sleepers on it and laying rails.
この高架鉄道にも進行方向の転換のための分岐器が設置されている。分岐器はポイント部、リード部、クロッシング部及びガードレールによって構成してあり、可動部分であるポイント部が作動上最も重要である。ところで、降雪地では列車の車体に付着した雪塊が分岐器通過時の衝撃によって分岐器上に落下し、或いは線路上に堆積した雪が列車のスノウプラウによって分岐器まで持ち込まれる結果、基本レールとトングレールとの間に雪が挟まって転換不能の事態が生じる問題があり、高架鉄道においても同様の問題がある。   This elevated railway is also equipped with a turnout for changing the direction of travel. The branching device is constituted by a point portion, a lead portion, a crossing portion and a guard rail, and the point portion which is a movable portion is the most important in operation. By the way, in a snowy area, snow blocks attached to the train's car body fall on the branch due to impact when passing through the branch, or snow accumulated on the track is brought to the branch by the train snow plow. There is a problem that snow cannot be converted due to snow between the rail and the same problem in the elevated railway.
このような雪塊などによる分岐器の転換不能の問題を解決する手段として、電熱式、熱風式、温水式などの除去手段が提案されており、また圧縮空気により雪塊などの異物を吹飛ばす方式の特許も提案されている(特許文献1)。

しかし、従来の電熱式、熱風式、温水式の除去手段は雪塊の除去に時間を要する、集中降雪に対応が困難という問題がある。圧縮空気による異物除去手段は相応の効果を奏するが、設備費が嵩む問題がある。   However, conventional electric heating type, hot air type, and hot water type removing means have problems that it takes time to remove snow blocks and it is difficult to cope with concentrated snowfall. Although the foreign matter removing means using compressed air has a corresponding effect, there is a problem that the equipment cost increases.
本発明は上述した従来技術の欠点や問題点に鑑みなされたもので、高架鉄道にあっても、列車から落下し、或いは持ち込まれる雪塊を速やかに融雪用凹部に収容することによって分岐器が転換不能になる事態を未然に防止し、また集中降雪にも対応でき、しかも融雪用凹部を設けることによる枕木の不安定性を解消した高架鉄道用分岐器融雪ピットを提供することを目的とする。   The present invention has been made in view of the above-described drawbacks and problems of the prior art. Even in an elevated railway, a branching device is provided by quickly storing a snow mass falling from a train or being brought into a recess for melting snow. An object of the present invention is to provide an elevated railway branching snow melting pit that can prevent the situation where it cannot be converted, can cope with concentrated snowfall, and eliminates the instability of sleepers due to the provision of a snow melting recess.
上述した課題を解決するために構成された本発明の手段は、鉄道用高架に鉄道線路の分岐器を支持すべく設置するピット躯体は、コンクリート製立方体からなる基部と、該基部に幅広溝状に形成され、上方が開放した有底の融雪用凹部と、前記基部の長手方向に離間して該融雪用凹部の両側壁から対向して突出した各一対の多数の枕木受け部とから構成し、前記融雪用凹部の底面には発熱体を配置し、前記ピット躯体には載架する枕木の端部側を夫々保持する横圧支承具を設けたものからなる。 The means of the present invention configured to solve the above-described problem is that a pit housing installed to support a railroad track branching device on a railroad overpass has a base made of a concrete cube, and a wide groove-like shape in the base. And a bottomed snow melting recess having an open top, and a pair of a plurality of sleeper receiving portions protruding in opposition from both side walls of the snow melting recess and spaced apart in the longitudinal direction of the base. A heating element is arranged on the bottom surface of the snow melting recess, and the pit housing is provided with a lateral pressure support for holding the end portions of the sleepers to be mounted.
そして、前記融雪用凹部は、防水工に施工してあるとよい。   And the said snow-melting recessed part is good to have constructed to waterproofing work.

本発明は以上詳述した如く構成したから、下記の諸効果を奏する。
(1)鉄道線路の分岐器を支持すべく鉄道用高架に設置するピット躯体は、列車により分岐器上に持込まれる雪塊や落下雪を融雪用凹部に収容して分岐器及びその周囲から雪を排除するので、高架鉄道においても分岐器の確実な作動を確保することができる。
(2)高所でスペースが狭く、作業や除雪に制約のある高架上での除雪作業を不要にできるので、列車の円滑な運行を確保できるし、除雪作業費を節減し作業員の安全確保にも資する。
(3)融雪用凹部は防水工に施工してあるから、融雪用凹部に滞留する融雪水がピット躯体に浸透してコンクリートを劣化させる事態を防止することができる。
(4)融雪用凹部は防水工に施工してあるから、ピット躯体によって防水工を施すことができないピット躯体下面の高架スラブにピット躯体を介して融雪水が浸透する事態を防止することができる。
(5)融雪用凹部によって下方が開放している枕木は、横圧支承具によって両端部側を保持した状態でピット躯体に載架したから、列車通過時に受ける負荷や振動に対して枕木を確実に保持することにより安全性を高めてある。
(6)枕木は一対の枕木受け部に各々載置する一対の枕木ブロックと、一対の枕木ブロックを連結する棒状連結材とから構成し、隣接する枕木との間に空間を確保したから、列車からの落下雪塊や持込み雪を枕木間に堆積させることなく速やかに融雪用凹部に落下させて収容できる。
(7)ピット躯体に、融雪用凹部に滞留する融雪水を鉄道線路に向けて噴射する循環式融雪水噴射装置を設けたから、分岐器に付着する雪塊も速やかに、かつ完全に除去することができ、分岐器を確実に作動させることができる。
(8)発熱体で加温されている融雪水を循環噴射するから、氷塊も速やかに融解して除去することができるし、別途給水源を設ける必要がないから高架においても設備費を節減できる。
Since the present invention is configured as described in detail above, the following effects can be obtained.
(1) The pit housing installed on the railway overpass to support the branching device on the railway track accommodates snow blocks and falling snow brought on the branching device by the train in the snow melting recess, and snow from the branching device and its surroundings. Therefore, reliable operation of the turnout can be ensured even in an elevated railway.
(2) Since the space is narrow at high places and snow removal work is not required on the elevated railway with restrictions on work and snow removal, smooth operation of the train can be ensured, snow removal work costs can be reduced, and worker safety can be ensured. Also contribute to.
(3) Since the snow melting recess is constructed by waterproofing, it is possible to prevent a situation where snow melting water staying in the snow melting recess penetrates into the pit housing and deteriorates the concrete.
(4) Since the snow melting recess is waterproofed, it is possible to prevent snowmelt water from penetrating into the elevated slab on the lower surface of the pit housing, which cannot be waterproofed by the pit housing, via the pit housing. .
(5) Since the sleepers that are open at the bottom by the snow melting recesses are mounted on the pit housing with both ends held by the lateral pressure bearings, the sleepers are reliably protected against the loads and vibrations that occur when passing through the train. The safety is improved by holding it.
(6) The sleepers are composed of a pair of sleeper blocks that are respectively placed on a pair of sleeper receiving portions and a rod-shaped connecting member that connects the pair of sleeper blocks, and a space is secured between the adjacent sleepers. Falling snow blocks and snow brought in can be quickly dropped into the snow melting recess without being accumulated between sleepers.
(7) Since the circulating smelting water injection device is provided in the pit housing to inject the snowmelt water staying in the snowmelt recess toward the railroad track, the snow mass adhering to the branching device should be removed quickly and completely. The branching device can be operated reliably.

The falling snow and the brought-in snow caused by the train are accommodated in the snow melting recess 4 so that the snow does not remain on the branching device 16 and the smooth conversion operation is not hindered. In addition, snow blocks and the like housed in the snow melting recess 4 are sequentially melted by the heating element 7 and drained to the ground from a drain groove (not shown).
また、列車の通過時には枕木12は横圧や振動を受けるが、特に融雪用凹部4によって下方が開放しており、道床によって全面的に支持されていない枕木12では両端部側12A、12Aにこれらの荷重が掛かるが、各枕木12は横圧支承具8で端部側12A、12Aを保持した状態でピット躯体2に載架することにより、植込みボルト13だけでなく横圧支承具8でも受けることにより安全性を確保している。   In addition, the sleepers 12 are subjected to lateral pressure and vibration when passing through the train, but in particular, the lower portions are opened by the snow melting recesses 4, and in the sleepers 12 that are not supported entirely by the roadbed, these are located on both end sides 12A and 12A. Although each sleeper 12 is mounted on the pit housing 2 while holding the end portions 12A and 12A with the lateral pressure support 8, it is received not only by the stud bolt 13 but also by the lateral pressure support 8. To ensure safety.
図6及び図7は第2の実施の形態を示す。なお、本実施の形態及び後述する他の実施の形態の構成要素において、第1の実施の形態の構成要素と同一の構成要素には同一の符号を付して援用し、その説明を省略する。図において21は、融雪用凹部4を跨ぐようにしてピット躯体2上に列設する枕木を示し、該枕木21は角柱状の一対の枕木ブロック22、22と、該一対の枕木ブロック22、22を連結する鋼管からなる棒状連結材23とから構成してある。   6 and 7 show a second embodiment. In the constituent elements of the present embodiment and other embodiments described later, the same constituent elements as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted. . In the figure, reference numeral 21 denotes a sleeper arranged on the pit housing 2 so as to straddle the snow melting recess 4, and the sleeper 21 includes a pair of rectangular pillar-shaped sleeper blocks 22, 22 and the pair of sleeper blocks 22, 22. It is comprised from the rod-shaped connection material 23 which consists of a steel pipe which connects.
本実施の形態は上述の構成からなり、レール15Aを設置する一対の枕木ブロック22、22は横圧指示具8で保持した状態で植込みボルト13、ナット14によってピット躯体2上に配置してある点では従来の枕木12と異ならない。しかし、枕木21の中間部分は鋼管の細い棒状連結材23にしてあり、隣接する枕木21との間に広い空間を形成しているから、列車による持込み雪塊や落下雪を枕木間に堆積させることなく融雪凹部4内に速やかに、確実に落下させることができ、分岐器16の作動を確保することができる。   This embodiment has the above-described configuration, and the pair of sleeper blocks 22 and 22 on which the rail 15A is installed are arranged on the pit housing 2 by the implantation bolts 13 and nuts 14 while being held by the lateral pressure indicator 8. In point, it is not different from conventional sleepers 12. However, the middle part of the sleeper 21 is a thin steel pipe-like connecting member 23, and a wide space is formed between the sleepers 21 adjacent to each other. It can be quickly and surely dropped into the snow melting recess 4 without any problem, and the operation of the branching device 16 can be secured.
また、上述の構成により、枕木21は制作時に樹脂と鋼管を一体成型することにより製造できるから、低廉化を図ることができるし、軽量化も図ることができ設置工事も容易である。しかも、枕木21は端部側22Aを横圧支承具8で保持して設置するから、十分な強度性を有することができる。なお、棒状連結材23は鋼管に代えて強度性のある合成樹脂管を用いてもよい。   Moreover, since the sleeper 21 can be manufactured by integrally molding a resin and a steel pipe at the time of production, the cost can be reduced, the weight can be reduced, and the installation work is easy. Moreover, since the sleepers 21 are installed by holding the end side 22A with the lateral pressure support member 8, the sleepers 21 can have sufficient strength. The rod-like connecting member 23 may be a strong synthetic resin pipe instead of a steel pipe.
図8は第3の実施の形態に係り、その特徴とするところはピット躯体2に循環式融雪水噴射装置31を設け、融雪用凹部4内で分岐器16に向けて噴射ノズル32、32から融雪水を噴射するようにしたことにある。図において、31は循環式融雪水噴射装置で、該循環式融雪水噴射装置31は融雪用凹部4内の横方向両側に沿って所定の間隔で、トングレール16Aに向けて配置した複数の噴射ノズル32、32と、融雪用凹部4内の融雪水を吸引して噴射する加圧ポンプ33と、該加圧ポンプ33に接続した吸水管34と、加圧ポンプ33、各噴射ノズル32、32を一連に連結する送水管35とから構成してある。なお、融雪用凹部4にある程度の融雪水を溜めて循環させるために、排水溝はオーバーフロー式にしてある。   FIG. 8 relates to the third embodiment, which is characterized in that a circulatory snow-melting water injection device 31 is provided in the pit housing 2 and is directed from the injection nozzles 32, 32 toward the branching device 16 in the snow-melting recess 4. The reason is that snowmelt water is jetted. In the figure, reference numeral 31 denotes a circulation type snowmelt water injection device, and the circulation type snowmelt water injection device 31 is a plurality of injections arranged toward the Tongler 16A at predetermined intervals along both lateral sides in the snowmelt recess 4. Nozzles 32, 32, a pressure pump 33 that sucks and injects the snowmelt water in the snowmelt recess 4, a water absorption pipe 34 connected to the pressure pump 33, a pressure pump 33, and each injection nozzle 32, 32. Are configured with a water pipe 35 that connects the two in series. In addition, in order to accumulate and circulate a certain amount of snowmelt water in the snowmelt recess 4, the drainage groove is an overflow type.
