Description

本発明は、例えば、高層住宅、高層ビル等に配された立管の内壁を洗浄するための立管洗浄装置および立管洗浄方法に関するものである。   The present invention relates to a vertical pipe cleaning device and a vertical pipe cleaning method for cleaning an inner wall of a vertical pipe disposed in, for example, a high-rise house or a high-rise building.

マンション等の大規模な集合住宅には、各住戸の流し台や洗面所等に配された個別の排水管を介して排出された生活廃水を一括して合流させ、それを公設の汚水枡や下水本管へと導くための排水管（共用部排水管、あるいは立管ともいう）が、マンションの外壁部に露出した状態あるいは壁内部に埋設された状態で、上層階から下層階に渡って配設されている。このような排水管は、多世帯からの日常的な生活廃水等により管の内側に汚れ（例えば、スライムや錆、水垢等）が付着するため、定期的に排水管の洗浄を行う必要がある。特に近年における生活スタイルの変化に伴ない、油脂分の使用量が増加していることによる排水管への油脂分の付着や、結晶化した尿石による流通不良あるいは排水管づまりが増大し、それが悪臭の原因となる等の弊害が発生している。   In large apartments such as condominiums, domestic wastewater discharged through individual drain pipes arranged in sinks and washrooms of each dwelling united together is combined into public wastewater sewage and sewage Drain pipes (also referred to as common area drain pipes or vertical pipes) leading to the main pipe are distributed from the upper floor to the lower floor in a state where they are exposed on the outer wall of the apartment or embedded in the wall. It is installed. Such drain pipes must be regularly cleaned because dirt (eg, slime, rust, scales, etc.) adheres to the inside of the pipes due to daily living wastewater from many households. . In particular, along with changes in lifestyles in recent years, there has been an increase in the amount of fats and oils attached to the drainage pipes, poor distribution due to crystallized urine stones, and drainage pipe clogging. Bad effects such as causing bad odor have occurred.

排水管内の付着物を取り除き、排水管を洗浄する方法として一般的に採用されるものには、例えば特許文献１に記載されているように高圧洗浄機より洗浄用ホースを排水管に挿入し、その先端のノズルから高圧水（ジェット水流）を噴出させて、管内の堆積物、錆等を粉砕、剥離させる高圧洗浄法、ワイヤーの先端部を特殊形状にし、ワイヤー自体を回転させながら管の中に挿入して清掃するワイヤー洗浄法等がある。また、管内の汚れ状況に応じて、ワイヤー洗浄法と高圧洗浄法とを併用する。   To remove the deposits in the drain pipe and to generally employ the method for washing the drain pipe, for example, as described in Patent Document 1, a washing hose is inserted into the drain pipe from a high pressure washer, A high pressure cleaning method that jets high pressure water (jet water flow) from the nozzle at the tip, crushes and separates deposits, rust, etc. in the tube, makes the tip of the wire a special shape, and turns the wire itself while rotating the wire itself There is a wire cleaning method to insert and clean. Moreover, the wire cleaning method and the high-pressure cleaning method are used in combination according to the state of dirt in the pipe.

なお、薬品を用いた洗浄方法もあるが、通常、強力な塩素系薬品を用いるため、浄化槽が設置されているマンションでは水質を悪化させる等、環境破壊を引き起こすおそれあり、特別な場合以外は採用されない。   Although there is a cleaning method using chemicals, usually strong chlorinated chemicals are used, so in condominiums where septic tanks are installed, there is a risk of causing environmental damage, such as deterioration of water quality. Adopted except in special cases. Not.

しかしながら、上述した従来の高圧洗浄法は、排水管（横管）の洗浄に適した方法であり、それを排水管（立管）の洗浄に適用した場合、例えば、立管の下部からホースを挿入して高圧洗浄する方法は、低・中層マンションの立管洗浄に使用できても、作業対象となる立管の垂直高が高い近年の超高層ビルや高層マンションにおける立管洗浄には対応できないという問題がある。また、このことを理由に、高層マンション等における立管の洗浄を長期間、放置あるいは断念する場合もあり、マンション管理上の問題となり得る。   However, the conventional high-pressure cleaning method described above is a method suitable for cleaning a drain pipe (horizontal pipe), and when it is applied to cleaning a drain pipe (stand pipe), for example, a hose is connected from the bottom of the vertical pipe. The method of inserting and performing high-pressure cleaning can be used for vertical pipe cleaning of low- and middle-rise apartments, but cannot support vertical pipe cleaning in recent high-rise buildings and high-rise apartments where the vertical height of the target vertical pipes is high. There is a problem. In addition, for this reason, there is a case where standing pipe cleaning in a high-rise apartment or the like is left or abandoned for a long time, which may be a problem in apartment management.

一方、立管の上部からホースを挿入して高圧洗浄する方法も考えられるが、通常、立管は下層階が必然的に詰まりやすく、上部からの洗浄法では、洗浄物の落下により却って立管下部の詰まりや汚れの状態を悪化させることになる。また、高圧ノズルから距離がある排水管の奥側部分ほど、水圧の低下により汚れが落ちにくくなる。そこで、各階ごとに掃除口にホースを入れて引き上げながら管内部を洗うのであるが、洗浄装置を各階に持ち込む必要があり作業に手間がかかり過ぎる上、高層部になるほど作業そのものに危険性を伴うため、作業員の足場の確保等に余分な時間と費用を要するという問題がある。   On the other hand, a method of inserting a hose from the top of the vertical pipe and performing high-pressure cleaning is also conceivable, but normally, the vertical pipe tends to clog the lower floors. This will worsen the clogging and dirt on the bottom. Moreover, the depth side part of the drain pipe which is far from the high-pressure nozzle becomes difficult to remove dirt due to a decrease in water pressure. Therefore, it is necessary to bring the hose into the cleaning port for each floor and wash the inside of the pipe while pulling it up, but it is necessary to bring the cleaning device to each floor, and it takes too much work, and the higher the part, the more dangerous the work itself is Therefore, there is a problem that extra time and cost are required for securing a scaffold for workers.

本発明は、上述の課題に鑑みてなされたもので、高層マンション等における共用立管の内部洗浄を容易かつ短時間に行える立管洗浄装置および立管洗浄方法を提供することを目的としている。   The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a standing tube cleaning apparatus and a standing tube cleaning method that can easily and quickly clean the inside of a common standing tube in a high-rise apartment or the like.

上記目的を達成するため、本発明は高圧ホースの先端に複数の噴出孔を穿設した洗浄ノズルを設け、その洗浄ノズルから噴射する高圧流体で立管内を洗浄する立管洗浄装置であって、上記高圧ホースに対して、その中心軸回りの回転を与える回転付与手段と、上記回転する高圧ホースを、上記立管内において垂直方向に進退させる進退手段とを備え、上記回転付与手段と進退手段とによって、上記複数の噴出孔のうち特定の噴出孔を上記立管の内壁に近接させながら上記洗浄ノズルを上記立管内で螺旋状に進行させることで、上記特定の噴出孔からの上記高圧流体の噴射圧によって上記立管の内壁の付着物を粉砕あるいは剥離することを特徴とする。   In order to achieve the above object, the present invention is a vertical pipe cleaning device provided with a cleaning nozzle having a plurality of ejection holes formed at the tip of a high pressure hose and cleaning the inside of the vertical pipe with a high pressure fluid sprayed from the cleaning nozzle, A rotation applying means for rotating the high-pressure hose around its central axis; and advancing / retreating means for moving the rotating high-pressure hose in the vertical direction in the vertical direction. By moving the cleaning nozzle in a spiral manner in the vertical pipe while bringing a specific jet hole out of the plurality of jet holes close to the inner wall of the vertical pipe, the high-pressure fluid from the specific jet hole The deposit on the inner wall of the vertical pipe is pulverized or peeled off by the injection pressure.

例えば、上記洗浄ノズルを上記立管の内壁に沿って下部側から上部側へ向けて垂直上方に螺旋状に進行させることで、上記立管の内壁を下部から上部の順に洗浄する。また、例えば、上記複数の噴出孔は上記洗浄ノズルの互いに正反対となる位置に穿設された２つ噴出孔からなり、一方の噴出孔の径が他方の噴出孔の径よりも大きいことを特徴とする。   For example, the inner wall of the vertical tube is cleaned in order from the lower side to the upper side by causing the cleaning nozzle to spirally move vertically upward from the lower side toward the upper side along the inner wall of the vertical tube. Further, for example, the plurality of ejection holes are composed of two ejection holes drilled at positions opposite to each other of the cleaning nozzle, and the diameter of one ejection hole is larger than the diameter of the other ejection hole. And

また、上記目的を達成するため、本発明に係る立管洗浄方法は、高圧流体を噴射する径の異なる複数の噴出孔を穿設した洗浄ノズルを先端に取り付けた高圧ホースを、立管内において、その高圧ホースの中心軸回りに回転するとともに、その回転する高圧ホースを前記立管内において垂直方向に進退させることによって、前記複数の噴出孔のうち特定の噴出孔を前記立管の内壁に近接又は接触させ、かつ前記洗浄ノズルを前記立管内で螺旋状に進行させることで、前記特定の噴出孔からの前記高圧流体の噴射圧によって前記立管の内壁の付着物を粉砕あるいは剥離することを特徴とする。   Further, in order to achieve the above object, the vertical tube cleaning method according to the present invention includes a high pressure hose in which a cleaning nozzle having a plurality of ejection holes with different diameters for injecting high pressure fluid is attached to the tip, By rotating the high-pressure hose around the central axis of the high-pressure hose and moving the high-pressure hose rotating in the vertical direction in the vertical pipe, a specific jet hole of the plurality of jet holes is close to the inner wall of the vertical pipe or The deposit on the inner wall of the vertical pipe is pulverized or peeled by the injection pressure of the high-pressure fluid from the specific ejection hole by bringing the cleaning nozzle into contact with each other and spirally moving in the vertical pipe. And

前記高圧ホースを前記立管の上端から下端に向けて垂下させ、先端の洗浄ノズルが立管の最下部に達したら、高圧ホースを、立管内において、その高圧ホースの中心軸回りに回転させるとともに、先端の洗浄ノズルから高圧流体を噴射させ、前記高圧ホースを引き上げることにより、前記洗浄ノズルを前記立管内で螺旋状に上昇させる構成としてもよい。   When the high-pressure hose is suspended from the upper end to the lower end of the vertical pipe and the cleaning nozzle at the tip reaches the lowest part of the vertical pipe, the high-pressure hose is rotated around the central axis of the high-pressure hose in the vertical pipe The cleaning nozzle may be spirally raised in the vertical pipe by injecting a high-pressure fluid from the cleaning nozzle at the tip and pulling up the high-pressure hose.

前記立管の上端から下端まで垂下した紐状体と、前記高圧ホースの先端の洗浄ノズルとを連結し、高圧ホースをその中心軸回りに回転させるとともに、先端の洗浄ノズルから高圧流体を噴射させ、前記紐状体を引き上げることにより、前記洗浄ノズルを前記立管内で螺旋状に上昇させる方法としてもよい。   The string-like body hanging from the upper end to the lower end of the vertical pipe is connected to the washing nozzle at the tip of the high-pressure hose, and the high-pressure hose is rotated around its central axis and the high-pressure fluid is ejected from the washing nozzle at the tip. The cleaning nozzle may be spirally raised in the vertical pipe by pulling up the string-like body.

本発明に係る立管洗浄装置および立管洗浄方法によれば、まず、洗浄ノズルに設けた径の異なる第１噴出孔と第２噴出孔とから同時に高圧流体を噴出させる。大きい径の噴出孔からの噴射の反力が大きいので、洗浄ノズルの小さい径の噴出孔側が、立管の一方の内壁に近接、あるいは摺接する。近接又は摺接した側の内壁は、小さい径の噴出孔からの高圧流体で洗浄される。高圧ホースが回転し、かつ、進行しているので、立管の内壁は小さい径の噴出孔からの高圧流体で螺旋状に洗浄される。洗浄ノズルを、立管内の下層部から上層部に向けて垂直上方に進行させることで、立管の内壁の全面をムラなく洗浄できることになる。   According to the vertical pipe cleaning device and the vertical pipe cleaning method according to the present invention, first, a high-pressure fluid is jetted simultaneously from the first and second jet holes having different diameters provided in the washing nozzle. Since the reaction force of the injection from the large-diameter ejection hole is large, the small-diameter ejection hole side of the cleaning nozzle comes close to or slidably contacts one inner wall of the vertical pipe. The inner wall on the side close to or in sliding contact is cleaned with the high-pressure fluid from the small-diameter ejection hole. Since the high-pressure hose is rotating and moving, the inner wall of the vertical pipe is spirally washed with the high-pressure fluid from the small-diameter ejection hole. By moving the cleaning nozzle vertically upward from the lower layer portion to the upper layer portion in the vertical pipe, the entire inner wall of the vertical pipe can be cleaned uniformly.

以下、本発明を実施するための最良の形態を図面に基づいて説明する。図１は、本発明の実施の形態例に係る立管洗浄装置の全体構成を示している。図１に示す立管洗浄装置１０は、超高層ビルや高層マンション等の高層建築物１に設けられた雑排水用の共用立管２０の内部・内壁洗浄に対応可能な装置であり、高圧流体（例えば、水を使用するが、その他、温水や環境に悪影響を与えない液体、あるいは空気等の気体を使用することも可能である。）の供給源１１と、ホース回転ユニット１２と、ホース進退装置１３と、高圧ホース１４と、ホースガイド１９と、高圧ホース１４の先端に取り付けられた洗浄ノズル１５とから構成される。   Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings. FIG. 1 shows the overall configuration of a standing tube cleaning apparatus according to an embodiment of the present invention. A vertical pipe cleaning apparatus 10 shown in FIG. 1 is an apparatus capable of cleaning the inner and inner walls of a common vertical pipe 20 for miscellaneous drainage provided in a high-rise building 1 such as a super high-rise building or a high-rise apartment. (For example, although water is used, it is also possible to use warm water, a liquid that does not adversely affect the environment, or a gas such as air.), A supply source 11, a hose rotating unit 12, and a hose advance / retreat The apparatus 13 includes a high pressure hose 14, a hose guide 19, and a cleaning nozzle 15 attached to the tip of the high pressure hose 14.

一般に超高層ビルやマンション等の高層建築物１では、各居住者世帯やテナントの台所や便器、手洗器等の排水口から下方向に排水管が伸び、それが床下で横方向に伸びる横枝管に接続されており、各横枝管はさらに、高層建築物１の最上階から地上へ垂直方向に伸びる共用立管２０に連なる構造になっている。この共用立管２０は、例えば、口径が１００〜２００ｍｍの硬質塩化ビニル等の樹脂からなり、各階層の横枝管を流れてきた排水を集中、合流させ、それを高層建築物１の敷地内の地下部等に配した横管４０へと誘導している。横管４０は、屋外公共ます４（あるいは、下水道本管）に接続されている。なお、図１では、各階層の横枝管や、共用立管２０と並行して垂直に走る通気管等の図示を省略する。   In general, in high-rise buildings 1 such as skyscrapers and condominiums, drainage pipes extend downward from the drainage outlets of each resident's household or tenant's kitchen, toilet, hand-washer, etc., and extend laterally under the floor. Each horizontal branch pipe is further connected to a pipe, and has a structure connected to a common stand pipe 20 extending vertically from the top floor of the high-rise building 1 to the ground. This common vertical pipe 20 is made of, for example, a resin such as hard vinyl chloride having a diameter of 100 to 200 mm, and concentrates and merges the drainage water flowing through the horizontal branch pipes of each level, and the same is installed in the site of the high-rise building 1 To the horizontal pipe 40 arranged in the underground part of the city. The horizontal pipe 40 is connected to the outdoor public mass 4 (or the sewer main). In FIG. 1, illustrations of horizontal branch pipes in each layer and ventilation pipes that run vertically in parallel with the common stand pipe 20 are omitted.

本発明の実施の形態例では、図１に示すように立管洗浄装置１０の高圧流体の供給源１１を地上に配置し、他のホース回転ユニット１２やホース進退装置１３等を、例えば、高層マンション等の高層建築物１の屋上に設置する。共用立管２０の洗浄作業は、最初に高圧ホース１４の先端部分（洗浄ノズル１５が接続された側）を、共用立管２０の最上部に設けられた開口部１８より挿入し、洗浄ノズル１５を最下部まで下ろした後、下層階から順次、上層階へ向けて、共用立管２０内において高圧ホース１４を垂直方向（図中の矢印ａ方向）へ移動させて行う。このように下層階側から上層階側へ順に洗浄を行うのは、共用立管２０は下層階側が詰まりやすく、上部から洗浄したのでは、落下した洗浄物により共用立管２０の下部が塞がれてしまい、洗浄効率や作業性が悪いからである。   In the embodiment of the present invention, as shown in FIG. 1, the high pressure fluid supply source 11 of the vertical tube cleaning device 10 is disposed on the ground, and the other hose rotating unit 12 and the hose advance / retreat device 13 are arranged, for example, in a high-rise building. Installed on the roof of high-rise buildings 1 such as condominiums. For the cleaning operation of the common stand pipe 20, first, the tip portion of the high-pressure hose 14 (the side to which the wash nozzle 15 is connected) is inserted from the opening 18 provided at the top of the common stand pipe 20, and the wash nozzle 15 Is moved to the upper floor sequentially from the lower floor, and the high pressure hose 14 is moved in the vertical direction (in the direction of arrow a in the figure) in the common vertical pipe 20. In this way, cleaning is performed in order from the lower floor side to the upper floor side. The common vertical pipe 20 is likely to be clogged in the lower floor side. This is because the cleaning efficiency and workability are poor.

なお、後述するように、本発明の実施の形態例に係る立管洗浄装置１０では、高圧ホース１４に対して、その中心軸回りに回転を与えることができる構成になっているため、洗浄ノズル１５を共用立管２０の開口部１８より挿入して最下部まで下ろす際にも、高圧ホース１４を回転させながら洗浄ノズル１５を下部へ送るという方法をとる。また、洗浄ノズル１５にはランス３が接続されているため、洗浄ノズル１５を降下させる際、このランス３が錘として機能する。その結果、共用立管２０の内壁の付着物３０の影響を受けずに、洗浄ノズル１５を目的とする最下部まで円滑に下ろすことができる。   As will be described later, in the vertical pipe cleaning device 10 according to the embodiment of the present invention, the high-pressure hose 14 is configured to be able to rotate around its central axis. Even when 15 is inserted through the opening 18 of the common vertical pipe 20 and lowered to the lowest position, the cleaning nozzle 15 is sent to the lower part while rotating the high-pressure hose 14. Further, since the lance 3 is connected to the cleaning nozzle 15, the lance 3 functions as a weight when the cleaning nozzle 15 is lowered. As a result, the cleaning nozzle 15 can be smoothly lowered to the lowest position without being affected by the deposits 30 on the inner wall of the common vertical pipe 20.

排水経路の水平部分である横管４０の内部洗浄は、従来の方法、すなわち屋外公共ます４等から高圧ホース１４を押し込み、その高圧ホース１４を軸方向へ回転させながら、図中の矢印ｂ方向（共用立管２０側）へ洗浄ノズル１５を移動させて、その洗浄ノズル１５の噴出孔から噴射された高圧流体で横管４０内の洗浄を行う。   The internal cleaning of the horizontal pipe 40, which is the horizontal part of the drainage path, is performed by the conventional method, that is, by pushing the high-pressure hose 14 from the outdoor public basin 4 etc. and rotating the high-pressure hose 14 in the axial direction. The cleaning nozzle 15 is moved to (the common standpipe 20 side), and the horizontal tube 40 is cleaned with the high-pressure fluid ejected from the ejection hole of the cleaning nozzle 15.

本発明の実施の形態例に係る立管洗浄装置１０の高圧流体の供給源１１としては、例えば、空気圧モータによる圧縮空気の流体エネルギーを動力源とする高圧ポンプを搭載した高圧洗浄車を使用する。この高圧洗浄車は、例えば１００ＭＰａ程度の高圧水を毎分１２０〜１８０リットル程度（最大２００リットル／分）で吐出する能力を有するものである。また、高圧ホース１４は、例えば、外径が１０ｍｍ、内径が５ｍｍのポリエチレン系の樹脂、あるいはウレタンＳＵＳ等の材質からなる（ブレードホース）。   As the high-pressure fluid supply source 11 of the vertical tube cleaning device 10 according to the embodiment of the present invention, for example, a high-pressure cleaning vehicle equipped with a high-pressure pump that uses fluid energy of compressed air by a pneumatic motor as a power source is used. . This high-pressure washing vehicle has a capability of discharging high-pressure water of, for example, about 100 MPa at a rate of about 120 to 180 liters per minute (maximum 200 liters / minute). The high-pressure hose 14 is made of, for example, a polyethylene resin having an outer diameter of 10 mm and an inner diameter of 5 mm, or urethane SUS (blade hose).

ここでは、洗浄ノズル１５より噴射する高圧流体の水量や、洗浄現場で使用する高圧ホース１４の総延長等に応じた、高圧ホース１４内での圧力損失を考慮して、高圧流体の供給源１１の圧力や接続ホース１６の口径、材質等を設定する。特に「超高層マンション」と呼ばれる高層建築物１は、垂直方向の高さが６０ｍを越えるため、接続ホース１６は、屋上等へ引き回して使用する際、その自重に抗する剛性を有することが望ましい。   Here, in consideration of the pressure loss in the high-pressure hose 14 according to the amount of high-pressure fluid ejected from the cleaning nozzle 15 and the total extension of the high-pressure hose 14 used at the cleaning site, the high-pressure fluid supply source 11 The pressure, the diameter of the connecting hose 16, the material, and the like are set. In particular, since the high-rise building 1 called “super high-rise apartment” has a vertical height exceeding 60 m, it is desirable that the connection hose 16 has rigidity to resist its own weight when used by being routed to the rooftop or the like. .

ホース回転ユニット１２は、高圧流体の供給源１１から接続ホース１６を介して高圧水を受け、それを高圧ホース１４に供給すると同時に、公知の構成（例えばエアモータ等）によって高圧ホース１４そのものに対し、その中心軸回りに回転を与える。このホース回転ユニット１２は、車輪１２ａを有しているため、高圧ホース１４が共用立管２０内を進退するのに連れて、図中の矢印ｃ方向に進退できるようになっている。また、この進退を軽快にするために、レールを敷設することが望ましい。なお、高圧ホース１４を共用立管２０内から一気に後退させる場合等において、その後退移動を速めるために、必要に応じてウィンチ１７を付加してもよい。   The hose rotating unit 12 receives high-pressure water from the high-pressure fluid supply source 11 via the connection hose 16 and supplies the high-pressure water to the high-pressure hose 14. A rotation is given around its central axis. Since the hose rotating unit 12 has wheels 12a, the hose rotating unit 12 can advance and retreat in the direction of arrow c in the drawing as the high-pressure hose 14 advances and retreats in the common standpipe 20. Moreover, in order to make this advance and retreat light, it is desirable to lay a rail. In the case where the high-pressure hose 14 is retracted from the common standpipe 20 at a stretch, a winch 17 may be added as necessary in order to speed up the backward movement.

共用立管２０を洗浄する際、上述したホース回転ユニット１２による高圧ホース１４の回転と相俟って、高圧ホース１４を共用立管２０内に円滑に進入させ、あるいは後退させるため、立管洗浄装置１０には、ホース進退装置１３とホースガイド１９が配されている。このホース進退装置１３は、例えば、図２に示すように２個のゴム製の支持車輪１３ａ，１３ｂと１個の送り車輪１３ｃとが設けられ、これらの間に回転する高圧ホース１４が挿通される。各車輪は、ホース進退装置１３の図示しないフレームに支持されている。３個の車輪１３ａ，１３ｂ，１３ｃはすべて高圧ホース１４に適当な圧力で接触しているが、そのうち、下側の２個の支持車輪１３ａと１３ｂは、その回転軸が高圧ホース１４の中心軸１４ａと平行であり、高圧ホース１４を下から支える。その結果、高圧ホース１４は、これら２個の車輪間の窪みに入り、安定して保持される。   When cleaning the common standpipe 20, in combination with the rotation of the high-pressure hose 14 by the hose rotation unit 12 described above, the high-pressure hose 14 smoothly enters or retracts into the common standpipe 20. The apparatus 10 is provided with a hose advance / retreat apparatus 13 and a hose guide 19. In the hose advance / retreat apparatus 13, for example, as shown in FIG. 2, two rubber support wheels 13a, 13b and one feed wheel 13c are provided, and a rotating high pressure hose 14 is inserted between them. The Each wheel is supported by a frame (not shown) of the hose advance / retreat device 13. The three wheels 13a, 13b, and 13c are all in contact with the high pressure hose 14 at an appropriate pressure. Among the two support wheels 13a and 13b on the lower side, the rotation axis is the central axis of the high pressure hose 14. It is parallel to 14a and supports the high-pressure hose 14 from below. As a result, the high-pressure hose 14 enters a recess between these two wheels and is stably held.

送り車輪１３ｃは、高圧ホース１４と斜めに接触するようになっている。この送り車輪１３ｃを支持する軸１３ｄは回動可能で、送り車輪１３ｃは、図３（ａ）に示すような接触角αが鋭角になる位置から、図３（ｂ）に示すように接触角αが鈍角になる位置との間で適当な接触角に設定できるようになっている。具体的には、送り車輪１３ｃがα＜９０゜の角度で高圧ホース１４に接触すると、高圧ホース１４は、図３（ａ）の左から右に向かって移動する。一方、送り車輪１３ｃが、図３（ｂ）に示すようにα＞９０゜の角度で高圧ホース１４に接触すると、高圧ホース１４は、同図の右から左に向かって移動する。   The feed wheel 13c is in contact with the high-pressure hose 14 at an angle. The shaft 13d that supports the feed wheel 13c can be rotated, and the feed wheel 13c has a contact angle as shown in FIG. 3B from a position where the contact angle α becomes an acute angle as shown in FIG. An appropriate contact angle can be set between the position where α is an obtuse angle. Specifically, when the feed wheel 13c contacts the high pressure hose 14 at an angle of α <90 °, the high pressure hose 14 moves from left to right in FIG. On the other hand, when the feed wheel 13c contacts the high pressure hose 14 at an angle of α> 90 ° as shown in FIG. 3B, the high pressure hose 14 moves from the right to the left in the figure.

このように、高圧ホース１４の回転方向を変更することなく、送り車輪１３ｃの高圧ホース１４に対する接触角αを変更するだけで、高圧ホース１４を共用立管２０内に進入させる方向、あるいは後退する方向へ自在に送ることができる。また、接触角αを増減することによって、前進・後退の速度を増減可能となる。   As described above, the direction in which the high pressure hose 14 enters the common vertical pipe 20 or moves backward simply by changing the contact angle α of the feed wheel 13c with the high pressure hose 14 without changing the rotation direction of the high pressure hose 14. Can be sent freely in any direction. Further, by increasing or decreasing the contact angle α, the forward / reverse speed can be increased or decreased.

高圧ホース１４は、管内の水圧に耐えるために所定の剛性を有していることから、ホース自身を鋭角等の急峻な角度で折り曲げることは難しい。そこで、ホース進退装置１３の下流側であって、共用立管２０の開口部１８の近傍には、図１に示すように複数個のローラー１９ａ〜１９ｄからなるホースガイド１９が配置されている。このホースガイド１９は、高圧ホース１４を開口部１８へ挿入し、共用立管２０内を進行させる際、あるいは洗浄作業のために共用立管２０内を徐々に引き上げる際に、高圧ホース１４に適当な曲がり角を持たせるための手段（ガイド部材）として機能する。   Since the high-pressure hose 14 has a predetermined rigidity to withstand the water pressure in the pipe, it is difficult to bend the hose itself at an acute angle such as an acute angle. Therefore, a hose guide 19 including a plurality of rollers 19a to 19d is disposed on the downstream side of the hose advance / retreat device 13 and in the vicinity of the opening 18 of the common standpipe 20, as shown in FIG. This hose guide 19 is suitable for the high-pressure hose 14 when the high-pressure hose 14 is inserted into the opening 18 and the inside of the common stand 20 is advanced or when the common stand 20 is gradually pulled up for cleaning work. It functions as a means (guide member) for giving a gentle bend.

具体的には、ホースガイド１９の４個のローラー１９ａ〜１９ｄが、開口部１８の手前で高圧ホース１４を支持し、その高圧ホース１４が開口部１８の近傍で適当な曲率を有する円弧を描いて、共用立管２０内へ円滑に挿入され、あるいは共用立管２０から引き上げることができるようになっている。その際、ローラー１９ａ〜１９ｄは、ホース進退装置１３による高圧ホース１４の前進・後退を妨げない程度に高圧ホース１４を支持するとともに、作業環境に応じた最適な曲率を得るため、個々のローラーがホース送り方向および垂直方向へ所定距離だけ移動可能となっている。   Specifically, the four rollers 19 a to 19 d of the hose guide 19 support the high-pressure hose 14 in front of the opening 18, and the high-pressure hose 14 draws an arc having an appropriate curvature near the opening 18. Thus, it can be smoothly inserted into the common standpipe 20 or pulled up from the common standpipe 20. At that time, the rollers 19a to 19d support the high-pressure hose 14 to such an extent that the hose advance / retreat apparatus 13 does not prevent the high-pressure hose 14 from moving forward and backward, and to obtain an optimal curvature according to the work environment, The hose feed direction and the vertical direction can be moved by a predetermined distance.

図４は、図１に示す立管洗浄装置におけるイ部の拡大図であり、本実施の形態例に係る立管洗浄装置における立管の洗浄方法を模式的に示している。また、図５は、高圧ホースの先端に取り付けられた洗浄ノズルの斜視図である。本実施の形態例に係る立管洗浄装置１０で使用する高圧ホース１４の先端部に接続された洗浄ノズル１５は、高圧水を噴射するために、図５に示すようにその先端近傍（ノズルチップ）に穴径の異なる第１噴出孔１５ａと第２噴出孔１５ｂを有する。第１噴出孔１５ａと第２噴出孔１５ｂの双方とも、洗浄ノズル１５の中心軸１５ｃに直交する方向に噴出孔するとともに、中心軸１５ｃに対して互いに１８０度異なる位置関係でノズルチップに穿設されている。   FIG. 4 is an enlarged view of a portion in the vertical tube cleaning apparatus shown in FIG. 1, and schematically shows a vertical tube cleaning method in the vertical tube cleaning apparatus according to this embodiment. FIG. 5 is a perspective view of the cleaning nozzle attached to the tip of the high-pressure hose. As shown in FIG. 5, the cleaning nozzle 15 connected to the tip of the high-pressure hose 14 used in the vertical pipe cleaning device 10 according to the present embodiment is near its tip (nozzle tip) as shown in FIG. ) Have a first ejection hole 15a and a second ejection hole 15b having different hole diameters. Both the first ejection hole 15a and the second ejection hole 15b are ejected in a direction orthogonal to the central axis 15c of the cleaning nozzle 15, and are formed in the nozzle tip at positions different from each other by 180 degrees with respect to the central axis 15c. Has been.

このように、第１噴出孔１５ａと第２噴出孔１５ｂが洗浄ノズル１５の中心軸１５ｃに対して直交する方向を向く構成とすることで、共用立管２０の内壁に対して効率的に高圧水を噴射でき、洗浄力が最も強くなる。ノズルチップは、洗浄作業環境、例えば、立管の管径や付着した固形物等に応じて洗浄ノズル１５に着脱自在な差し替え式になっている。また、ノズルチップを交換することによって、第１噴出孔１５ａと第２噴出孔１５ｂの径が異なる組合せのものを使用することができるので、種々の開口径の組み合わせを持ったノズルチップを用意して、洗浄する立管の径や高圧水の吐出圧、吐出量等に応じて適当なものを適宜、選択可能となる。   As described above, the first ejection hole 15a and the second ejection hole 15b are configured to face the direction orthogonal to the central axis 15c of the cleaning nozzle 15, so that the inner wall of the common standpipe 20 is efficiently high-pressure. Water can be jetted and the cleaning power is strongest. The nozzle tip is of a replaceable type that can be attached to and detached from the cleaning nozzle 15 in accordance with the cleaning work environment, for example, the diameter of the vertical pipe or the attached solid matter. In addition, by changing the nozzle tip, it is possible to use a combination with different diameters of the first ejection hole 15a and the second ejection hole 15b. Therefore, nozzle tips having various combinations of opening diameters are prepared. Thus, an appropriate one can be appropriately selected according to the diameter of the vertical pipe to be cleaned, the discharge pressure of high-pressure water, the discharge amount, and the like.

なお、第１噴出孔１５ａと第２噴出孔１５ｂの開口方向は、上記の例に限定されるものではなく、例えば、洗浄ノズル１５の中心軸１５ｃに対してやや後方（共用立管２０内での洗浄ノズル１５の進行方向と逆の方向）に傾斜させる構成としてもよい。   In addition, the opening direction of the 1st ejection hole 15a and the 2nd ejection hole 15b is not limited to said example, For example, it is a little behind (inside the common vertical pipe 20) with respect to the central axis 15c of the washing nozzle 15. The cleaning nozzle 15 may be inclined in the direction opposite to the traveling direction of the cleaning nozzle 15.

さらに、洗浄ノズル１５の噴出孔数も１対の第１噴出孔と第２噴出孔による２個に限定されず、例えば、２対、合計４個の噴出孔を形成する等、複数対の噴出孔を設けることも可能である。このように噴出孔数が多くなると、それに伴いノズル全体としての吐出水量が増加するので、管壁の洗浄速度も向上するが、吐出水量の増加は、高圧流体の供給源１１の能力で許容される範囲に限定されることになる。   Further, the number of ejection holes of the cleaning nozzle 15 is not limited to two by a pair of first ejection holes and second ejection holes. For example, a plurality of pairs of ejections are formed, for example, two pairs, for example, a total of four ejection holes are formed. It is also possible to provide holes. As the number of ejection holes increases in this way, the discharge water amount of the entire nozzle increases accordingly, so that the cleaning speed of the tube wall is improved. However, the increase in the discharge water amount is allowed by the ability of the high pressure fluid supply source 11. It will be limited to the range.

次に、図４等を参照しながら、本実施の形態例に係る立管洗浄装置１０における共用立管２０の洗浄方法について説明する。上述したように、高圧ホース１４とともに洗浄ノズル１５を共用立管２０内の目的とする最下部まで下降させた後、その洗浄ノズル１５のノズルチップに正反対の向きに設けられた第１噴出孔１５ａと第２噴出孔１５ｂから高圧水を噴射して洗浄を開始する。供給源１１より高圧ホース１４を介して供給された高圧水は、図４に示すように第１噴出孔１５ａと第２噴出孔１５ｂの双方から同時に噴射されるが、ここでは、第２噴出孔１５ｂの径が第１噴出孔１５ａの径よりも大きいため、第２噴出孔１５ｂからの噴出水Ａの水量が第１噴出孔１５ａからの噴出水Ｂの水量よりも多くなる。   Next, a method for cleaning the common standpipe 20 in the standpipe cleaning apparatus 10 according to this embodiment will be described with reference to FIG. 4 and the like. As described above, after the cleaning nozzle 15 is lowered together with the high-pressure hose 14 to the lowermost target in the common vertical pipe 20, the first ejection hole 15a provided in the opposite direction to the nozzle tip of the cleaning nozzle 15 is provided. Then, high pressure water is jetted from the second jet holes 15b to start cleaning. The high-pressure water supplied from the supply source 11 through the high-pressure hose 14 is simultaneously injected from both the first injection hole 15a and the second injection hole 15b as shown in FIG. Since the diameter of 15b is larger than the diameter of the 1st ejection hole 15a, the quantity of the ejection water A from the 2nd ejection hole 15b becomes larger than the quantity of the ejection water B from the 1st ejection hole 15a.

洗浄ノズル１５は、水平方向において、上記の両噴出孔１５ａ、１５ｂから噴出される水が共用立管２０の内壁に衝突して得た反力のバランスした位置、すなわち、共用立管２０の一方の管壁（図４では第１噴出孔１５ａのある右側の管壁）に近接又は接触した位置に移動する。また、垂直方向には、ホース進退装置１３によって共用立管２０内の高圧ホース１４に対して付与された引き上げ力と、高圧ホース１４内部に滞留する高圧水の重量とホースの自重、さらに洗浄ノズル１５とランス３の自重とで決まる位置に洗浄ノズル１５が移動する。   In the horizontal direction, the cleaning nozzle 15 has a balanced position of reaction forces obtained when the water ejected from both the ejection holes 15a and 15b collides with the inner wall of the common vertical pipe 20, that is, one side of the common vertical pipe 20 It moves to a position close to or in contact with the tube wall (the tube wall on the right side with the first ejection hole 15a in FIG. 4). Further, in the vertical direction, the pulling force applied to the high pressure hose 14 in the common stand pipe 20 by the hose advance / retreat apparatus 13, the weight of the high pressure water staying inside the high pressure hose 14, the own weight of the hose, and the washing nozzle The cleaning nozzle 15 moves to a position determined by 15 and the weight of the lance 3.

このとき高圧ホース１４には、上述したようにホース回転ユニット１２によって、その中心軸回りに回転が与えられているため、洗浄ノズル１５も高圧ホース１４と一緒に回転する。そして、洗浄ノズル１５の回転により噴出孔１５ａ，１５ｂからの高圧水の噴射方向も変化する。その結果、洗浄ノズル１５は共用立管２０の内壁に近接した状態で円軌道を描き、さらに、この回転に対してホース進退装置１３により洗浄ノズル１５と高圧ホース１４とに引き上げる力（共用立管２０内を上昇させる力）が加わるので、結局、洗浄ノズル１５は、図４に示すように、共用立管２０内を垂直上方に螺旋状に進む。したがって、管壁に近い噴出孔１５ａから噴射された噴出水Ａの噴射圧によって、共用立管２０の内壁の付着物３０（例えば、スライムや錆等のスケール）の粉砕や剥離が行われる。同時に、高圧ホース１４の回転速度と、ホース進退装置１３による引き上げ速度とを適当に設定することによって満遍なく洗浄ができ、洗浄ムラが生じるのを回避できる。   At this time, since the high pressure hose 14 is rotated around its central axis by the hose rotating unit 12 as described above, the cleaning nozzle 15 also rotates together with the high pressure hose 14. And the injection direction of the high-pressure water from the ejection holes 15a and 15b is also changed by the rotation of the cleaning nozzle 15. As a result, the cleaning nozzle 15 draws a circular orbit in the state of being close to the inner wall of the common standpipe 20, and further, the hose advancing / retreating device 13 with respect to this rotation pulls up the cleaning nozzle 15 and the high pressure hose 14 (common standpipe). As a result, the cleaning nozzle 15 spirally moves vertically upward in the shared standpipe 20, as shown in FIG. Therefore, the deposit 30 (for example, a scale such as slime or rust) on the inner wall of the common vertical pipe 20 is pulverized or peeled off by the jet pressure of the jet water A jetted from the jet hole 15a close to the pipe wall. At the same time, by setting the rotation speed of the high-pressure hose 14 and the pulling speed by the hose advance / retreat apparatus 13 appropriately, cleaning can be performed uniformly, and occurrence of cleaning unevenness can be avoided.

洗浄ノズル１５からの噴出水で粉砕等された付着物３０は、噴出水とともに、そのまま共用立管２０内を垂直に落下し、図１に示すように、共用立管２０の最下部に接続された横管４０方向へと流される。そして、最終的に屋外公共ます４に達し、そこに集積されたスケール３１は、あらかじめ配車された吸引車５によって回収される。この屋外公共ます４は、スケール３１を除去した後の排水を、図１において矢印で示す方向に流すため、図示しない市町村の公共の排水管、排水施設へと繋がっている。   The adhering material 30 crushed by the jet water from the washing nozzle 15 falls vertically together with the jet water in the common vertical pipe 20, and is connected to the lowermost part of the common vertical pipe 20 as shown in FIG. It flows in the direction of the horizontal tube 40. And finally it reaches the outdoor public mass 4, and the scale 31 accumulated there is collected by the suction vehicle 5 that has been dispatched in advance. Since the outdoor public slab 4 drains the waste water after removing the scale 31 in the direction indicated by the arrow in FIG. 1, it is connected to a public drain pipe or drainage facility in a municipality not shown.

本発明の実施の形態例に係る立管洗浄装置１０では、洗浄ノズル１５が共用立管２０内において螺旋状に後退する（垂直方向へ引き上げられる）と、ホース回転ユニット１２も高圧ホース１４とともに共用立管２０から遠ざかる方向へ移動するが、ホース進退装置１３は固定されている。したがって、高圧ホース１４の共用立管２０内からの引上げにより、ホース回転ユニット１２が所定距離、後退した時点で洗浄を一旦中止し、引き抜いた分の高圧ホース１４を取り外してホースの全長を短くしてからホース回転ユニット１２を前進させた後、再び上記と同じ洗浄作業を開始する。そして、洗浄ノズル１５が共用立管２０の最上端に達したところで洗浄作業を完了する。この方法は、高層建築物１の屋上等、限られたスペースで立管洗浄装置１０を用いて行う洗浄作業に有効である。   In the vertical tube cleaning apparatus 10 according to the embodiment of the present invention, when the cleaning nozzle 15 is spirally retracted (pulled up in the vertical direction) in the common vertical tube 20, the hose rotating unit 12 is also shared with the high-pressure hose 14. The hose advance / retreat device 13 is fixed while moving away from the vertical pipe 20. Therefore, when the hose rotating unit 12 is retracted by a predetermined distance by pulling the high-pressure hose 14 from the common standpipe 20, the cleaning is temporarily stopped, and the pulled-out high-pressure hose 14 is removed to shorten the total length of the hose. Then, after the hose rotating unit 12 is advanced, the same cleaning operation as described above is started again. The cleaning operation is completed when the cleaning nozzle 15 reaches the uppermost end of the common standpipe 20. This method is effective for a cleaning operation performed using the standing tube cleaning device 10 in a limited space such as a rooftop of the high-rise building 1.

以上説明したように、高圧水を供給可能な高圧ホースの先端に洗浄ノズルを設け、それをマンション等の共用立管の最上部から挿入して最下部へ到達させた後、高圧水を噴射しながら洗浄ノズルを螺旋状に回転させて立管の最上部まで引き上げ、移動させることで、立管の下部側から上部側へと順にその内壁の付着物、堆積物、錆等を簡単かつ迅速に粉砕あるいは剥離することができる。また、共用立管の垂直下部側から洗浄を開始し、付着物で狭まっていた立管の内腔を広げた後に、その上部の汚れ等を落とす手順をとることで、粉砕等されて上階から落下した付着物が再び立管を詰まらせることを回避でき、ムラのない立管洗浄が可能となる。   As explained above, a cleaning nozzle is installed at the tip of a high-pressure hose that can supply high-pressure water, and it is inserted from the top of a common standpipe such as an apartment to reach the bottom, and then high-pressure water is injected. While rotating the cleaning nozzle spirally, pulling it up to the top of the vertical pipe and moving it, it is easy and quick to remove deposits, deposits, rust, etc. on the inner wall in order from the lower side to the upper side of the vertical pipe It can be crushed or peeled off. In addition, cleaning was started from the vertical lower side of the common standpipe, and after expanding the lumen of the standpipe that had been narrowed by deposits, the upper floor was crushed by taking steps to remove dirt, etc. Therefore, it is possible to avoid the adhering material that has fallen from clogging the vertical pipe again, and the vertical pipe can be cleaned evenly.

また、高圧ホースを共用立管最上部の開口部から挿入し、立管内を進行あるいは後退させる際に、その開口部において高圧ホースに適当な曲がり角を持たせるためのガイド部材を開口部の近傍に配することで、洗浄中に作業員が高圧ホースを保持等する必要がなく、安全に洗浄作業を行うことができる。   In addition, when a high pressure hose is inserted from the opening at the top of the common standpipe, when advancing or retreating the inside of the standpipe, a guide member for giving the high pressure hose an appropriate bending angle at the opening is provided near the opening. By arranging, it is not necessary for the worker to hold the high-pressure hose during cleaning, and the cleaning operation can be performed safely.

なお、共用立管２０の内壁洗浄は上記の構成をとる立管洗浄装置１０による方法に限定されず、例えば、図６に示すように、先端に洗浄ノズル１５を配した高圧ホース１４を、高層マンション等の高層建築物１に配された共用立管２０の最下部４３から挿入し、さらに洗浄ノズル１５にワイヤやロープ等の紐５０を結束するとともに、その紐５０によって、共用立管２０の最上部にある開口部１８を通して、洗浄ノズル１５を垂直上方に移動可能に支持する構成としてもよい。なお、図６において、高圧流体の供給源やホース回転ユニット、ホース進退装置等の図示を省略する。   The cleaning of the inner wall of the common vertical pipe 20 is not limited to the method using the vertical pipe cleaning apparatus 10 having the above-described configuration. For example, as shown in FIG. It is inserted from the lowermost portion 43 of the common vertical pipe 20 arranged in the high-rise building 1 such as an apartment, and further, a string 50 such as a wire or a rope is bound to the cleaning nozzle 15. The cleaning nozzle 15 may be supported so as to be movable vertically upward through the opening 18 at the top. In FIG. 6, illustration of a high-pressure fluid supply source, a hose rotation unit, a hose advancement / retraction device, and the like is omitted.

図６に示す構成では、高層建築物１の屋上の開口部１８近傍に滑車５３を配し、その滑車５３を支点として、巻き取り装置５５で紐５０を矢印方向へ徐々に巻き取ることで、共用立管２０内で高圧ホース１４を洗浄ノズル１５とともに垂直に起立させた状態を維持しながら、高圧ホース１４に水圧をかけて洗浄ノズル１５から高圧流体を噴出させ、紐５０を徐々に引き上げることで共用立管２０内において洗浄ノズル１５を垂直上方へ移動させることができる。このような構成とすることで、共用立管２０内で高圧ホース１４が自重に負けて座屈等することもないため、ムラなく立管内部の付着物３０等の粉砕あるいは剥離が可能となる。また、ホース回転ユニット１２と、ホース進退装置１３とを屋上に上げる必要もなくなり、接続ホース１６も短くすることができる。   In the configuration shown in FIG. 6, a pulley 53 is arranged in the vicinity of the opening 18 on the roof of the high-rise building 1, and the string 50 is gradually wound in the arrow direction by the winding device 55 with the pulley 53 as a fulcrum. While maintaining the state in which the high-pressure hose 14 is erected vertically together with the cleaning nozzle 15 in the common standpipe 20, the high-pressure fluid is jetted from the cleaning nozzle 15 by applying water pressure to the high-pressure hose 14, and the string 50 is gradually pulled up. Thus, the cleaning nozzle 15 can be moved vertically upward in the common standpipe 20. By adopting such a configuration, the high pressure hose 14 does not lose its own weight in the common vertical pipe 20 and does not buckle, so that the deposits 30 and the like inside the vertical pipe can be pulverized or separated without any unevenness. . Moreover, it is not necessary to raise the hose rotating unit 12 and the hose advance / retreat apparatus 13 to the roof, and the connecting hose 16 can be shortened.

なお、この例においても洗浄作業の際に高圧ホース１４は、その中心軸回りに回転し、洗浄ノズル１５からは高圧水が噴射されると同時に、その洗浄ノズル１５が螺旋状に回転して共用立管２０の内部を上昇するが、この回転により紐５０が捩れるのを防止するため、例えば、洗浄ノズル１５と紐５０との結合部に互いに自在に回転するような撚り戻しを設けるとよい。   In this example as well, the high pressure hose 14 rotates around its central axis during the cleaning operation, and at the same time as the high pressure water is jetted from the cleaning nozzle 15, the cleaning nozzle 15 rotates spirally and is shared. In order to prevent the string 50 from being twisted by this rotation, for example, it is preferable to provide untwisting so as to freely rotate at the joint between the cleaning nozzle 15 and the string 50. .
