Description
この発明は、既設の融雪管内をクリーニングし、塗装することができる既設融雪管の品質保全工法に関する。 The present invention relates to a quality maintenance method for an existing snow melting tube capable of cleaning and painting an existing snow melting tube.
現行の融雪管は、黒ガス管が主に使用されており、防錆対策がなされていないので、どんどん腐食が進み、管の厚みの保持が難しい状況である。 The current snow melting tube is mainly a black gas tube, and since rust prevention measures are not taken, the corrosion progresses rapidly and it is difficult to maintain the thickness of the tube.
そこで、この発明の目的は、黒ガス管と水とが直接接触する面をなくし、管の腐食に歯止めをかけ、配管の延命を図ることができる既設融雪管の品質保全工法を提供することにある。 Accordingly, an object of the present invention is to provide a quality maintenance method for an existing snowmelt tube that eliminates the surface where the black gas pipe and water are in direct contact, stops corrosion of the pipe, and extends the life of the pipe. is there.
かかる目的を達成するためのこの発明の構成は、既設の融雪本管を所定の施工スパンで切断する切断工程と、施工スパンに通したワイヤを介してワイヤブラシを往復させるとともに管内に水を送り込み、管内の錆を除去して水洗するクリーニング工程と、管内の水を除去する排水工程と、エアホース、塗装ホースをまとめて施工スパンに引き入れ、エアで回転する塗装ノズルにエポキシ樹脂塗料を供給して遠心力噴霧させながら一定速度で管内面を塗装する塗装工程と、塗料の硬化後、ファイバスコープを融雪本管に挿入して仕上り状況を確認する確認工程とを順に実施することをその要旨とする。 In order to achieve this object, the configuration of the present invention includes a cutting process for cutting an existing snowmelt main pipe at a predetermined construction span, a reciprocating wire brush through the wire passed through the construction span, and feeding water into the pipe. , Remove the rust in the pipe and wash it with water, drain the process to remove the water in the pipe, draw the air hose and paint hose together into the construction span, and supply the epoxy resin paint to the coating nozzle that rotates with air The gist is to perform the painting process of painting the inner surface of the pipe at a constant speed while spraying with centrifugal force, and the confirmation process of inserting the fiberscope into the snow melting main pipe and checking the finished state in order after the paint is cured. .
なお、電動ブラシまたは水噴霧によりノズル取付管内を除錆するノズル取付管クリーニング工程をクリーニング工程の前に実施し、エポキシ樹脂塗料の噴霧によりノズル取付管内を塗装するノズル取付管塗装工程を塗装工程の後に実施することができる。 In addition, the nozzle mounting pipe cleaning process, which rusts the inside of the nozzle mounting pipe with an electric brush or water spray, is performed before the cleaning process, and the nozzle mounting pipe coating process, in which the nozzle mounting pipe is painted by spraying epoxy resin paint, Can be implemented later.
融雪管内面のクリーニングに続き、塗膜を作成することによって、管寿命の延長を図り、赤水が道路に流されることにより道路のコンクリート面、アスファルト面が赤く変色することを防止する効果がある。 Following the cleaning of the inner surface of the snow-melting tube, it is possible to extend the life of the tube by creating a coating film, and to prevent the concrete surface and asphalt surface of the road from being discolored red due to the flow of red water on the road.
なお、この発明は、管体の厚みがあり、材質が強固であればベストの施工効果を発揮できるから、新設されてから出来るだけ早期に施工することが好ましい。また、道路上での施工が大部分を占めるから、交通の円滑さを保ちながら施工するために、道路の幅員が大きいことが好ましく、塗装機やコンプレッサ、ウィンチなども、小型のものが好ましい。 In addition, since this invention can exhibit the best construction effect if the thickness of the pipe body is strong and the material is strong, it is preferable that the construction is performed as soon as possible after the new construction. Moreover, since the construction on the road occupies most, it is preferable that the width of the road is large in order to carry out the construction while maintaining smooth traffic, and the painting machine, the compressor, the winch and the like are preferably small.
また、塗料は、クリーニング後の少しの残存錆に溶け込み、錆とともに固化するものを管全体に圧送すれば、管に生じた孔やコンクリートの亀裂部にも浸透する効果がある。 In addition, if the paint dissolves in a small amount of residual rust after cleaning and is solidified together with the rust, the paint has the effect of penetrating into holes formed in the pipe and cracks in the concrete.
以下、この発明の施工工程を順に説明する。 Hereafter, the construction process of this invention is demonstrated in order.
なお、施工前に、融雪ノズルの中央部を外し、ファイバスコープを融雪本管内にまで差し込み、管内の状況を確認する。 Before construction, remove the center part of the snow melting nozzle, insert the fiberscope into the snow melting main pipe, and check the situation inside the pipe.
（１）切断工程
既設の融雪本管を５０〜８０ｍの施工スパンで切断する。
(1) Cutting process The existing snow melting main is cut with a construction span of 50 to 80 m.
（２）クリーニング工程
施工スパンの管末からピアノ線を差し込み、施工スパンに貫通させる。ピアノ線にワイヤの先を結び、ピアノ線を引っ張ることにより施工スパンの管内にワイヤを通し、施工スパンの両端に設置するウィンチに接続する。口径に準じたワイヤブラシ、またはそれに類する物をワイヤに取り付け、ワイヤを介して交互に往復させることにより、管内の錆、スケール、水垢などを除去する。その際、給水車から圧力ポンプにより水を同時に管内に送り込み、錆を流し、管内を水洗する。
(2) Cleaning process Insert a piano wire from the end of the construction span and let it penetrate the construction span. The end of the wire is tied to the piano wire, and the wire is passed through the pipe of the construction span by pulling the piano wire, and connected to winches installed at both ends of the construction span. A wire brush according to the caliber, or the like, is attached to the wire and reciprocated alternately through the wire to remove rust, scale, scale, etc. in the pipe. At that time, water is simultaneously fed into the pipe from the water truck by a pressure pump, rust is washed away, and the pipe is washed with water.
（３）排水工程
コンプレッサにて、管内にたまった水をおおむね除去する。
(3) Drainage process Remove almost all water accumulated in the pipe with a compressor.
（４）塗装工程
エアホース、塗装ホースをまとめて１本化したホースを施工スパンにワイヤで引き入れる。エアにより末端の塗装ノズルを回転させ、それに塗料を送り込み、管内に遠心力噴霧させながら、ウィンチで一定速度（管径により速度調節）で手前に巻き取って移動させ、施工スパンの管内を塗装する。
(4) Painting process Combine the air hose and painting hose into a single hose into the construction span. Rotate the coating nozzle at the end by air, feed the paint into it, spray it into the pipe with centrifugal force, wind it up with a winch at a constant speed (adjust the speed according to the pipe diameter) and move it to paint the pipe in the construction span .
（５）確認工程
塗料の硬化時間後に、再度融雪ノズルの中央部または管末よりファイバスコープを挿入し、仕上り状況を確認する。
(5) Confirmation process After the curing time of the paint, a fiberscope is inserted again from the center of the snow melting nozzle or the end of the tube, and the finished state is confirmed.
（６）ノズル取付管クリーニング工程
融雪ノズルの中央部からノズル取付管内に高圧水噴霧ガンを挿入し、水噴霧によりノズル取付管内を除錆する。ただし、水噴霧は、電動ブラシに代えてもよい。なお、この工程は、融雪本管のクリーニング工程の前に実施する。
(6) Nozzle mounting tube cleaning process A high pressure water spray gun is inserted into the nozzle mounting tube from the center of the snow melting nozzle, and the nozzle mounting tube is derusted by water spray. However, the water spray may be replaced with an electric brush. This process is performed before the snow melting main cleaning process.
（７）ノズル取付管塗装工程
融雪ノズルの中央部からノズル取付管内に高圧塗装ガンを挿入し、エポキシ樹脂塗料の噴霧によりノズル取付管内を塗装する。ただし、この工程は、融雪本管の塗装工程の後に実施する。
(7) Nozzle mounting pipe painting process A high pressure paint gun is inserted into the nozzle mounting pipe from the center of the snow melting nozzle, and the inside of the nozzle mounting pipe is painted by spraying an epoxy resin paint. However, this process is performed after the process of painting the snowmelt main.
