Description

本発明は、鉄道線路の路盤内に埋設された伏びを補修する技術に関し、詳しくは、損傷のある伏びの内周面にライナー層を形成することにより補修する方法に関する。   The present invention relates to a technique for repairing a sag embedded in a roadbed of a railroad track, and more particularly to a method of repairing by forming a liner layer on an inner peripheral surface of a damaged sag.

鉄道線路の軌道を支える路盤には、農業用水を横断させて線路両側間の通水を確保したり、生活排水や雨水等の排水路とするなどの目的で、「伏び」と称される通水管が軌道を横切るように埋設されている。伏びの多くは陶管・ヒューム管などで製作されるため、長期間にわたって鉄道車両の振動や荷重などを受ける結果、また老朽化により、ひび割れを起こしたり破管したり継ぎ目が外れたりする等の損傷を招くことがあった。伏びに損傷が発生すると、発生個所から土砂が伏び内へ流入することにより、路盤に空洞が形成され、やがて路盤陥没を引き起こす原因となる。   The roadbed that supports the track of the railway track is referred to as “slave” for the purpose of crossing the agricultural water to ensure water flow between both sides of the track, or to make it a drainage channel for domestic wastewater, rainwater, etc. A water pipe is buried so as to cross the track. Since most of the prone are made of ceramic pipes and fume pipes, they are subject to vibrations and loads of railway vehicles over a long period of time, and due to aging, cracks, pipe breaks, and seams break off. Could cause damage. When damage occurs in the sag, the earth and sand flow into the sag from the location where it occurs, forming a cavity in the roadbed and eventually causing the roadbed to collapse.

このような不具合の有る伏びを発見した場合、伏びを交換することが考えられる。しかしながら、その作業には大形の機械装置が必要であり、伏びの埋設箇所は幹線道路から離れている場合が多いため、このような大形機械装置を用いる伏びの交換は実際的には困難であった。そこで、伏びの簡便な補修手段として、特許文献1に記載の方法が提案されている。   If you find a prone defect such as this, you can consider replacing it. However, since large-scale machinery is required for the work, and the place where the burial is buried is often away from the main road, exchanging the burial using such a large-sized machine is practical. Was difficult. Then, the method of patent document 1 is proposed as a simple repair means of a prone.

特許文献1に記載される伏びの補修方法は、伏び内にスリップシートを挿通敷設し、このスリップシート上に折り畳んだチューブ状のライナー部材を挿通し、次いでライナー部材内に水蒸気を送り込んで膨らませつつ、該ライナー部材を加熱して硬化させることにより、伏びの内周面にライナー層を形成するというものである。
上記伏びの補修方法によれば、ひび割れを起こしたり破管したり継ぎ目が外れた伏びを交換することなく、簡易に補修することができる。そして、必要基材は比較的小型であるから、施工現場が幹線道路から離れていても、短時間で伏びの補修ができるという効果が発揮されるとされている。
In the method of repairing the sag described in Patent Document 1, a slip sheet is inserted and laid in the sag, a tube-shaped liner member folded on the slip sheet is inserted, and then water vapor is fed into the liner member. While inflating, the liner member is heated and cured to form a liner layer on the inner peripheral surface of the sag.
According to the above-described repair method for the sag, it is possible to easily repair the slab without causing a crack, breakage of the pipe, or replacement of the sag from which the seam has been removed. And since the required base material is comparatively small, even if the construction site is away from the main road, it is said that the effect of repairing the proneness in a short time is exhibited.

特開2000−355050号公報JP 2000-355050 A

特許文献1に記載の伏び補修方法は、ライナー部材を膨らませ硬化させるのに水蒸気を使用する。従って、水蒸気の供給装置を必要とするが、通常の水蒸気供給装置は人手により運搬するのが困難な大きさ・重量であるため、機動性が悪く、寄りつきの悪い施工現場への適用が難しいという問題があった。そこで、水蒸気供給装置を施工現場から離れた個所に設置し、長いホースを用いて水蒸気を供給することも考えられるが、この場合は、供給路の距離が長くなるために水蒸気の温度低下の問題が生じる。また、高温の水蒸気を使用するから、作業者がこれに触れて火傷を負う危険を確実に防止できる措置を講じる必要があった。さらに、ライナー部材内へ送り込んだ水蒸気は凝縮して水となるから、この凝縮水をライナー部材内から排出する手段を設ける必要がある。しかもその上、排出時の凝縮水は比較的高温なので、これを作業者と接触させないようにする工夫が必要であった。   The prone repair method described in Patent Document 1 uses water vapor to inflate and cure the liner member. Therefore, a water vapor supply device is required, but the normal water vapor supply device has a size and weight that are difficult to carry by hand, so it is difficult to apply to a construction site with poor mobility and poor contact. There was a problem. Therefore, it is conceivable to install a water vapor supply device at a location away from the construction site and supply water vapor using a long hose. Occurs. In addition, since high-temperature steam is used, it is necessary to take measures that can reliably prevent the risk of burns by touching the worker. Furthermore, since the water vapor sent into the liner member is condensed into water, it is necessary to provide means for discharging the condensed water from the liner member. In addition, since the condensed water at the time of discharge is relatively high temperature, it is necessary to devise a means for preventing it from coming into contact with the worker.

本発明は、前記従来技術の問題点を解消して、使用装置の構成をより簡単且つ軽量にすることができると共に、機動性・安全性に優れた伏びの補修方法を提供することを目的とする。   It is an object of the present invention to solve the problems of the prior art and to provide a method for repairing proneness that can make the configuration of the apparatus used simpler and lighter and has excellent mobility and safety. And

本発明が採用する伏び補修方法の特徴とするところは、請求項1に記載する如く、常温で硬化するライニング材料をチューブ状に成形し、その内表面及び外表面をガスバリヤ性の高いフィルムで被覆して補修用ライナー部材を製作し、該ライナー部材を伏び内へ挿通し、該ライナー部材の一方の端部を閉塞すると共に、他方の端部に通気口を有する閉塞部材を装着し、該閉塞部材の通気口から上記ライナー部材の内表面を被覆するインナーフィルム内へ加圧空気を送り込むことにより上記ライナー部材を膨らませて伏びの内周面に圧接させたのち、上記ライナー部材が地熱で硬化するまでライナー部材内部の加圧状態を維持して伏びの内周面にライナー層を形成することである。   According to the present invention, the prosthetic repair method is characterized in that, as described in claim 1, a lining material that cures at room temperature is formed into a tube shape, and the inner surface and outer surface thereof are made of a film having a high gas barrier property. A liner member for repair is manufactured by covering, and the liner member is inserted into the prone, and one end portion of the liner member is closed, and a closing member having a vent hole is attached to the other end portion, The liner member is expanded and pressed against the inner peripheral surface of the prone surface by sending pressurized air from the vent of the closing member into the inner film covering the inner surface of the liner member. In other words, the pressure inside the liner member is maintained until it is cured by forming a liner layer on the inner peripheral surface of the sag.

前記において、補修用ライナー部材を構成するライニング材料は、繊維状の補強材に常温硬化性の合成樹脂を含浸させたものであり、補強材には、例えばガラスロービング、PETフェルト、ポリエステル繊維シート、又は、これらの複合材若しくは積層材等が挙げられる。常温硬化性の合成樹脂とは、例えば不飽和ポリエステル樹脂、ビニルエステル樹脂、エポキシ樹脂などであって、硬化開始温度を15〜30°Cに調整したものが用いられる。   In the above, the lining material constituting the repair liner member is obtained by impregnating a fibrous reinforcing material with a room temperature curable synthetic resin. Examples of the reinforcing material include glass roving, PET felt, polyester fiber sheet, Or these composite materials or a laminated material etc. are mentioned. The room temperature curable synthetic resin is, for example, an unsaturated polyester resin, a vinyl ester resin, an epoxy resin, or the like, and a resin whose curing start temperature is adjusted to 15 to 30 ° C. is used.

チューブ状に成形したライニング材料の内表面及び外表面を覆うガスバリヤ性の高いフィルムとは、通気性が皆無又はきわめて低い性質のフィルムであり、さらに耐薬品性・耐熱性・耐蝕性を持ち、スチレン等の有機溶剤に対し非透過性であることが望ましい。このようなものとしては、例えばナイロンとポリエチレンとの複層フィルムが考えられる。ナイロンはガスバリヤ性を発揮し、ポリエチレンは引っ張り強度と柔軟性とを付与する。   A highly gas barrier film that covers the inner and outer surfaces of a lining material formed into a tube shape is a film that has no or very low air permeability, and has chemical resistance, heat resistance, and corrosion resistance. It is desirable that it is impermeable to organic solvents such as. As such a thing, the multilayer film of nylon and polyethylene can be considered, for example. Nylon exhibits gas barrier properties, and polyethylene provides tensile strength and flexibility.

本発明に係る伏びの補修方法は、伏び内に挿通したチューブ状のライナー部材を、常温で硬化するライニング材料で成形したので、ライナー部材を膨らませる手段は加圧空気でよく、また伏びが埋設されている路盤の地熱でライナー部材を硬化させるものである。それ故、補修作業を実施するのに水蒸気等の熱源を必要としないから、従来の如き水蒸気供給装置や、凝縮水の排出手段や、水蒸気及び排出水に対する安全対策を不要にできると共に、ライナー部材の硬化に要する時間を除いた実作業時間を、大幅に短縮することができる。また、必要とする機械装置を軽量化・小型化できると共に、設備構成が簡略になるから機動性が向上し、その結果、寄りつきの悪い施工現場に対しても補修作業の実施が可能となる。   In the method for repairing the proneness according to the present invention, since the tubular liner member inserted into the proneness is formed of a lining material that cures at room temperature, the means for inflating the liner member may be pressurized air, and The liner member is hardened by the geothermal heat of the roadbed in which the bridge is embedded. Therefore, since a heat source such as water vapor is not required for carrying out the repair work, it is possible to eliminate the conventional water vapor supply device, condensed water discharge means, and safety measures against water vapor and discharged water, and the liner member. The actual work time, excluding the time required for curing, can be greatly reduced. In addition, the required mechanical device can be reduced in weight and size, and the equipment configuration is simplified, so that the mobility is improved. As a result, it is possible to perform repair work even on a construction site where the approach is poor.

以下、本発明に係る伏びの補修方法の一実施形態を、図面に基づいて説明する。図1に示すように、鉄道線路Sは一般に、土台である路盤Pの上に、所定の厚さに盛り上げたバラスト等で道床Qを形成し、その上に配設した枕木M上に軌道Rを敷設して構築される。そして伏びFが、軌道Rを横切る方向に、所定間隔を置いて路盤P内に埋設される。伏びFは、主として農業用水や生活排水・雨水などを、線路Sを横断して通水させるためのものである。   Hereinafter, an embodiment of a prone repair method according to the present invention will be described with reference to the drawings. As shown in FIG. 1, the railroad track S generally forms a roadbed Q with ballast or the like raised to a predetermined thickness on a base roadbed P, and a track R on a sleeper M arranged thereon. Is built and laid. The prone F is embedded in the roadbed P at a predetermined interval in the direction crossing the track R. The bow F is mainly for passing agricultural water, domestic wastewater, rainwater, etc. across the track S.

伏びFには、ヒューム管のほか、古くから陶製のものが多用されてきており、鉄道車両の走行による振動や荷重などの影響で、ひび割れを起こしたり、破管したりする。また伏びFが、複数本の管を連結して構成されている場合は、継ぎ目が外れることがある。そこで補修作業に当たっては、各伏びFについて、ひび割れ・破管・継ぎ目外れ等の損傷の有無を調査し、補修が必要と判断された伏びFについて、以下に説明する手順により、内周面にライナー層を形成する。   In addition to the fume tube, ceramics have long been used for the prone F, and it is cracked or broken by the influence of vibration or load caused by running of a railway vehicle. Further, when the protuberance F is configured by connecting a plurality of pipes, the joint may be disconnected. Therefore, in the repair work, the presence of damage, such as cracks, broken pipes, and seams, is investigated for each of the prostheses F. A liner layer is formed.

まず始めに、伏びFの状況及び周囲の環境について事前調査を行なう。具体的には、伏びの施工位置及び周囲の状況・施工基面の状況・機材搬入路の状況・伏びの管径及び延長・伏び内温度・外気温などについて検査又は測定を行なう。   First, a preliminary survey will be conducted regarding the condition of the prone F and the surrounding environment. Specifically, inspection or measurement is performed on the position of the prone position and surroundings, the condition of the construction base, the condition of the equipment carry-in route, the diameter and extension of the prone area, the internal temperature of the prone area, and the outside air temperature.

次いで、図1に示す如く、適宜の清掃器具10や浚渫装置、高圧洗浄水等を用いて、伏びF内の堆積物除去・清掃・洗浄等を施す。続いて、図2に示す如く、例えばTVカメラ21と記録装置22とから成る検査装置20により伏びF内周面の観察・撮影を行い、ひび割れや破管や継ぎ目の外れ等の損傷の有無を調査する。   Next, as shown in FIG. 1, deposit removal, cleaning, washing, etc. in the prone F are performed using an appropriate cleaning tool 10, a dredge device, high-pressure washing water, or the like. Subsequently, as shown in FIG. 2, for example, the inspection device 20 including the TV camera 21 and the recording device 22 is used to observe and shoot the inner surface of the prone F, and whether there is damage such as cracks, broken pipes, and seams being removed. To investigate the.

調査の結果、伏びFが損傷を有し補修の必要が有ると判断したならば、エアコンプレッサーや発電機等の必要機材を搬入し設置する。そして図3に示すように、必要に応じて伏びF内にスリップシート30を挿通したのち、その上に補修用ライナー部材40を敷設する。このとき、ライナー部材40の先端を、伏びFの開口端部よりも突出させておくことが望ましい。   As a result of the investigation, if it is determined that the prone F is damaged and needs to be repaired, the necessary equipment such as an air compressor and generator will be carried in and installed. And as shown in FIG. 3, after inserting the slip sheet | seat 30 in the prone F as needed, the liner member 40 for repair is laid on it. At this time, it is desirable to make the tip of the liner member 40 protrude from the opening end of the prone F.

スリップシート30は、伏びFの損傷部分でライナー部材40が傷つくのを防止すると同時に、伏びF内へライナー部材40を引き込むのを円滑にするためのものであって、比較的強靱でスリップ性の良好な素材、例えばポリエチレン・ポリプロピレン・ナイロン等の合成樹脂製シートから成る。   The slip sheet 30 is intended to prevent the liner member 40 from being damaged at the damaged portion of the prone F, and at the same time to facilitate the drawing of the liner member 40 into the prone F, and is relatively strong and slippery. It is made of a material having good properties, for example, a synthetic resin sheet such as polyethylene, polypropylene, and nylon.

補修用ライナー部材40は、図4(A)に示す如く、常温硬化性のライニング材料41をチューブ状に成形し、同図(B)に示す如く、その内表面及び外表面をガスバリヤ性の高いインナーフィルム42及びアウターフィルム43で被覆したものである。ライニング材料41は、繊維質の補強材に常温硬化性の合成樹脂を含浸させて構成される。補強材としては、ガラスロービング、PETフェルト、ポリエステル繊維シート等のほか、これを複合させたもの、あるいは積層したものが用いられる。常温硬化性の合成樹脂には、例えば不飽和ポリエステル樹脂、ビニルエステル樹脂、エポキシ樹脂などであって、硬化開始温度を15〜30°Cに調整したものが用いられる。従ってライナー部材40は、施工直前まで、例えば10°C以下の保冷コンテナなどに保管することが好ましい。またチューブ状に成形したライニング材料41の層厚みは、補修対象となる伏びFの管径に応じて設定されるが、管径200〜450mmに対しては4mm程度とすればよい。またライニング材料41の望ましい機械的性質は、硬化後の曲げ強さが50N/mm以上、曲げ弾性率が4000N/mm以上である。 As shown in FIG. 4 (A), the repair liner member 40 is formed from a room temperature curable lining material 41 in a tube shape. As shown in FIG. 4 (B), the inner surface and the outer surface have high gas barrier properties. The inner film 42 and the outer film 43 are covered. The lining material 41 is configured by impregnating a fibrous reinforcing material with a room temperature curable synthetic resin. As the reinforcing material, glass roving, PET felt, polyester fiber sheet, etc., as well as composites or laminates thereof are used. As the room temperature curable synthetic resin, for example, an unsaturated polyester resin, a vinyl ester resin, an epoxy resin, or the like having a curing start temperature adjusted to 15 to 30 ° C. is used. Therefore, it is preferable to store the liner member 40 in, for example, a cold storage container of 10 ° C. or less until just before the construction. Moreover, although the layer thickness of the lining material 41 shape | molded in the tube shape is set according to the pipe diameter of the sag F which becomes repair object, what is necessary is just to be about 4 mm with respect to the pipe diameter 200-450 mm. The desirable mechanical properties of the lining material 41, the bending strength after curing 50 N / mm 2 or more, the flexural modulus is 4000 N / mm 2 or more.

ライニング材料41の内表面を覆うインナーフィルム42及び外表面を覆うアウターフィルム43には、例えばナイロンとポリエチレンとを熱融着させた複層フィルムなどの、通気性を持たず、耐薬品性・耐熱性・耐蝕性を有し、有機溶剤に対し非透過性の素材が用いられる。   The inner film 42 that covers the inner surface of the lining material 41 and the outer film 43 that covers the outer surface do not have air permeability, such as a multilayer film obtained by thermally fusing nylon and polyethylene, and are resistant to chemicals and heat. Materials that are resistant to corrosion and resistant to organic solvents.

なおライナー部材40には、長手方向の引っ張り強度が大きく且つ伸び率が小さいものを用いることが望ましい。これにより、伏びF内への引き込み時における長手方向の伸縮を抑制して、層厚みの変動を防止できる。他方、径方向の伸び率は適度に大きいことが望ましい。これにより、後述する加圧空気の供給工程において、ライナー部材40を伏びFの内周面へ確実に密着させることができる。   In addition, it is desirable to use the liner member 40 having a large tensile strength in the longitudinal direction and a small elongation rate. Thereby, the expansion / contraction of the longitudinal direction at the time of drawing in into the sag F can be suppressed, and the fluctuation | variation of layer thickness can be prevented. On the other hand, it is desirable that the elongation in the radial direction is moderately large. Thereby, the liner member 40 can be reliably adhered to the inner peripheral surface of the prone F in a step of supplying pressurized air to be described later.

前記の如く構成されるライナー部材40は、伏びF内への挿入を容易にするため、例えば図4(C)に示す如く、径方向に圧縮して折り畳んだ状態で使用するのが望ましい。   The liner member 40 configured as described above is preferably used in a state of being compressed and folded in the radial direction, for example, as shown in FIG.

ライナー部材40を伏びF内へ引き込んでスリップシート30上に敷設したのち、必要に応じ、基端側を伏びFの開口部の近傍位置で切断する。そして図5に示すように、ライナー部材40の両端部にプラグと呼ばれる閉塞部材50(a),50(b)を装着し、気密的に締結する。締結手段52には、ワイヤー・バンド・ロープなどが用いられる。   After the liner member 40 is drawn into the sag F and laid on the slip sheet 30, the base end side is cut at a position near the opening of the sag F as necessary. Then, as shown in FIG. 5, closing members 50 (a) and 50 (b) called plugs are attached to both ends of the liner member 40 and fastened in an airtight manner. For the fastening means 52, a wire, a band, a rope, or the like is used.

先端側の閉塞部材(プラグ)50bは、開口部の無いものを用いるが、基端側の閉塞部材50aには、通気口51を有するものを用いる、そして、この通気口51に、エアコンプレッサー60に連結したエアホース61を接続し、エアコンプレッサー60からエアホース61を通じて、ライナー部材40のインナーフィルム42内へ加圧空気を供給する。これにより、ライナー部材40が膨らみ、伏びFの内周面に圧接する。しかるのち、エアコンプレッサー60により供給される加圧空気の供給圧を一定に保ち、ライナー部材40の圧接状態を所定時間以上維持する。   As the closing member (plug) 50b on the distal end side, a member having no opening is used, but as the closing member 50a on the proximal end side, a member having a vent 51 is used, and an air compressor 60 is provided in the vent 51. An air hose 61 connected to the air hose 61 is connected, and pressurized air is supplied from the air compressor 60 through the air hose 61 into the inner film 42 of the liner member 40. As a result, the liner member 40 swells and presses against the inner peripheral surface of the prone F. Thereafter, the supply pressure of the pressurized air supplied by the air compressor 60 is kept constant, and the pressure contact state of the liner member 40 is maintained for a predetermined time or more.

ライナー部材40を構成しているライニング材料41は、常温硬化性の合成樹脂を含浸させたものであるから、外気温にもよるが、普通は施工開始時から硬化を開始し、伏びF内へ敷設されてからは、伏びFが埋設されている路盤Pの地熱により硬化が進行する。従って、ライナー部材40内の空気圧を一定以上に保った状態を、所定時間以上維持することにより、ライナー部材40が硬化して、伏びFの内周面にライナー層が形成されることになる。加圧空気の保持時間は、ライニング材料41に用いた常温硬化性合成樹脂の物性や、伏びF内の温度によって決まるが、硬化完了まで24〜28時間を要する場合が多い。本発明では、路盤Pの地熱でライナー部材40の硬化が進行するから、外気温が多少低くても、ライナー部材40を確実に硬化させることができるという利点を有する。なお外気温が低いときは、硬化工程の間、ライナー部材40における伏びFの両管端部から露出している部分を保温材で被覆することが望ましい。   Since the lining material 41 constituting the liner member 40 is impregnated with a room temperature curable synthetic resin, although it depends on the outside air temperature, the lining material 41 usually starts to be cured from the start of the construction, After being laid, the hardening proceeds due to the geothermal heat of the roadbed P in which the underlay F is embedded. Therefore, by maintaining the state in which the air pressure in the liner member 40 is maintained at a certain level or more for a predetermined time or longer, the liner member 40 is cured and a liner layer is formed on the inner peripheral surface of the sag F. . The holding time of the pressurized air is determined by the physical properties of the room temperature curable synthetic resin used for the lining material 41 and the temperature in the sag F, but it often takes 24 to 28 hours to complete the curing. In the present invention, since the curing of the liner member 40 proceeds by the geothermal heat of the roadbed P, there is an advantage that the liner member 40 can be reliably cured even if the outside air temperature is somewhat low. When the outside air temperature is low, it is desirable to cover the exposed portions of both ends of the pipe F of the liner F in the liner member 40 with a heat insulating material during the curing process.

ライナー部材40の硬化が完了したならば、ライナー部材40内から圧力を抜き、図6(A)に示す如く、ライナー部材40における伏びFから突出している部分を切断し、プラグ50a、50bの取り外しを行なう。そして、インナーフィルム42除去し、伏びFの両端開口部に仕上げ処理を施す。しかる後、必要に応じ、TVカメラ21を用いた検査装置20(図2参照)で、伏びF内部の施工状態を検査し、補修作業を完了する。   When the curing of the liner member 40 is completed, the pressure is released from the inside of the liner member 40, and as shown in FIG. 6A, the portion of the liner member 40 protruding from the sag F is cut, and the plugs 50a and 50b are cut. Remove. Then, the inner film 42 is removed, and a finishing process is performed on the opening portions at both ends of the sag F. Thereafter, if necessary, the inspection apparatus 20 using the TV camera 21 (see FIG. 2) is used to inspect the construction state inside the prone F and complete the repair work.

以上述べた如く、本発明に係る伏びの補修方法によれば、必要機材として、エアコンプレッサー・発電機・検査装置を用意すればよく、従来必要としていた水蒸気発生装置と比較すると設備規模が格段に縮小されるので、人手による機材の運搬・搬入が可能になり、機動性が向上する。また熱源を使用しないから、安全対策を簡単に済ませられる。さらに水蒸気を使用しないことにより、補修作業における実作業時間が大幅に短縮されるから、鉄道車両の運行スケジュールにより作業可能時間が制限されている個所に対しても、適用が可能である。   As described above, according to the method for repairing proneness according to the present invention, it is only necessary to prepare an air compressor, a generator, and an inspection device as necessary equipment. Therefore, the equipment can be transported and loaded manually, and the mobility is improved. Moreover, since no heat source is used, safety measures can be easily completed. Furthermore, by not using water vapor, the actual work time in the repair work is greatly shortened. Therefore, the present invention can be applied to places where the workable time is limited by the operation schedule of the railway vehicle.
