Description

本発明は、横方向に配設される排水管の内部洗浄方法に関し、より詳しくは、シンクのディスポーザによって粉砕処理された卵殻や貝殻等の比重が重い残留物が堆積する排水管に好適な内部洗浄方法に関する。   The present invention relates to a method for cleaning the inside of a drain pipe disposed in a lateral direction. More specifically, the present invention relates to an interior suitable for a drain pipe in which residues such as eggshells and shells pulverized by a sink disposer are deposited. The present invention relates to a cleaning method.

従来、シンクの排水を建屋の縦方向に配設される排水縦本管へ流す排水横管や この排水縦本管下端部に接続される排水横主管の内部を洗浄する際は、これらの排水管に1箇所もしくは複数個所に設けてある排水管内の残留物を排出するための清掃口から高圧水を後方噴射できるノズルを先端に設けたホースを排水管内に挿入し、ノズルから高圧水を放射状に噴射させるとともに、このホースを進退させながら残留物を排出するための清掃口方向に向けて移動させ、排水管の内壁に付着している付着物や排水管内に堆積する堆積物を洗浄し、かつノズルから噴射する高圧水によってこの洗浄した汚れを、残留物を排出するための清掃口に向けて押し流し、この清掃口からバキューム吸引機等で吸引除去している(例えば、特許文献1参照)。   Conventionally, when cleaning the drainage horizontal pipe that flows the sink drainage to the drainage main pipe arranged in the vertical direction of the building and the drainage horizontal main pipe connected to the lower end of this drainage main pipe, Insert a hose with a nozzle at the tip that can spray high-pressure water backward from the cleaning port to discharge the residue in the drain pipe provided in one or more places in the pipe, and discharge the high-pressure water radially from the nozzle. In addition, the hose is moved forward and backward toward the cleaning port to discharge the residue, and the deposits adhering to the inner wall of the drain pipe and the deposits deposited in the drain pipe are washed, The washed dirt is washed away by a high-pressure water sprayed from a nozzle toward a cleaning port for discharging the residue, and suctioned and removed from the cleaning port with a vacuum suction machine or the like (for example, see Patent Document 1). .

しかしながら、シンクのディスポーザによって粉砕処理された卵殻や貝殻等のように比重が重い堆積残留物は、堆積量が少ない場合は、ノズルから噴射する高圧水によって残留物を排出するための清掃口の方向に押し流すことができるが、この卵殻や貝殻等の比重が重い残留物が押し流されるにつれて次第に集まり、排水管内に山を作るまで集まってしまうと、もはや高圧水の噴射では押し流すことができなくなるのである。   However, if the deposit is heavy, such as eggshells and shells crushed by the sink disposer, the direction of the cleaning port for discharging the residue with high-pressure water sprayed from the nozzle is low However, if heavy residues such as eggshells and shells gather gradually as they are swept away and gather until they form a mountain in the drain, they can no longer be swept away by high-pressure water jets. .

このように、比重の重い卵殻や貝殻等の残留物が集まって山になると、ノズルから噴射された高圧水による水の流れが清掃口まで到達しないため、排水管内に比重の重い卵殻や貝殻等の残留物が集まる山ができたことが分かる。
したがってこのような場合には、ノズルから高圧水を噴射しながらこのノズルが山の頂上前後を進退するよう先端にノズルを設けたホースを操作し、卵殻や貝殻等の残留物が集まってできた残留物の山の頂上部からこの残留物を少量ずつ清掃口に向けて押し流さなければならい。
In this way, when residues such as eggshells and shells with heavy specific gravity gather and become mountains, the flow of high-pressure water sprayed from the nozzle does not reach the cleaning port, so eggshells and shells with heavy specific gravity in the drain pipe It can be seen that there was a mountain where the residues of the mine gathered.
Therefore, in such a case, while the high pressure water was jetted from the nozzle, the hose provided with the nozzle at the tip was operated so that the nozzle moved forward and backward around the top of the mountain, and residues such as eggshells and shells gathered. The residue must be swept away from the top of the residue pile into the cleaning port in small portions.

またノズルから噴射される高圧水は放射状に後方噴射されるので、この高圧水を山の頂上部にピンポイントで噴射することが極めて困難で、堆積残留物が集まってできた残留物の山を崩すには、ノズルが山の頂上前後を進退するよう何回もホースを操作しなければならない。
したがって、排水管内の堆積残留物が多い場合は、熟練技術および非常に手間と時間が掛かる作業を必要としていた。
Moreover, since the high-pressure water sprayed from the nozzles is sprayed radially backward, it is extremely difficult to pinpoint this high-pressure water to the top of the mountain, and the pile of the residue that is formed by the accumulation of accumulated residue To break down, the hose must be operated many times so that the nozzle moves back and forth around the top of the mountain.
Therefore, when there is a large amount of accumulated residue in the drain pipe, skillful techniques and work that is very laborious and time consuming are required.

特開2004−267900号公報(第1〜10頁、図1〜10)JP 2004-267900 A (pages 1 to 10, FIGS. 1 to 10)

本発明は、排水管内に堆積する卵殻や貝殻等の比重の重い残留物が多い場合であっても、短時間で確実に排水管内を洗浄することができる排水管の内部洗浄方法を提供できるようにした。   The present invention can provide an internal cleaning method for a drain pipe that can reliably clean the inside of the drain pipe in a short time even if there are many residues with heavy specific gravity such as eggshells and shells deposited in the drain pipe. I made it.

上述した課題を解決するために、本発明に係る排水管の内部洗浄方法は、横方向に配設する排水管の内部洗浄方法であって、同排水管内に、この排水管に設けられた排水管内の残留物を排出するための清掃口方向に所定の流速の空気を流通させるとともに、排水管内に水を送り込んでこの水を基に排水管内に水塊を生成し、かつこの水塊によって排水管内の一部分を閉塞して前記排水管内を流通する空気の流通を遮断し、水塊前後の排水管内における気圧を高、低に変化させながら水塊を気圧が低となる前記清掃口方向に移動させ、この水塊によって排水管内の残留物を前記清掃口方向に流して除去するものとしてある。   In order to solve the above-described problem, a drain pipe internal cleaning method according to the present invention is a drain pipe internal cleaning method arranged in a lateral direction, and a drain provided in the drain pipe in the drain pipe. Air of a predetermined flow velocity is circulated in the direction of the cleaning port for discharging the residue in the pipe, and water is sent into the drain pipe to generate a water mass in the drain pipe, and the water mass is drained by this water mass. Blocking a part of the pipe and blocking the flow of air flowing through the drainage pipe, moving the water mass toward the cleaning port where the atmospheric pressure is low while changing the pressure inside the drain pipe before and after the water mass to high and low The water mass is used to remove the residue in the drain pipe by flowing in the direction of the cleaning port.

また前記清掃口から排水管内の空気を吸引し、排水管内に清掃口方向に流通する気流を発生させるものとしてある。   In addition, the air in the drain pipe is sucked from the cleaning port, and an airflow flowing in the direction of the cleaning port is generated in the drain pipe.

さらに前記排水管に前記清掃口が複数配設されている場合、同排水管内の残留物を排出するための排出用清掃口方向へ向けて、他の清掃口から所定の流速の空気を吹き込んで流通させるものとしてある。   Further, when a plurality of the cleaning ports are arranged in the drain pipe, air of a predetermined flow velocity is blown from another cleaning port toward the discharge cleaning port for discharging the residue in the drain pipe. It is intended to be distributed.

また前記清掃口から排水管内に送水ホースを挿入し、この送水ホースから送水する水流によって排水管内の水を波立たせ、この波を前記水塊に成長させるものとしてある。   Further, a water supply hose is inserted into the drainage pipe from the cleaning port, and the water in the drainage pipe is rippled by the water flow supplied from the water supply hose, and this wave grows into the water mass.

また 前記送水ホースを清掃口から排水管内の所望の位置まであらかじめ挿入し、その後、送水ホースからその挿入方向とは逆向きに送水を行いながらこの送水ホースを清掃口方向に引き寄せるものとしてある。   In addition, the water supply hose is inserted in advance from the cleaning port to a desired position in the drain pipe, and then the water supply hose is pulled toward the cleaning port while water is supplied from the water supply hose in the direction opposite to the insertion direction.

さらに前記排水管に前記清掃口が複数配設されている場合、同排水管内の残留物を排出するための排出用清掃口方向へ向けて、他の清掃口から排水管内に挿入した送水ホースから送出する水流によって排水管内の水を波立たせ、この波を前記水塊に成長させるものとしてある。   Further, when a plurality of the cleaning ports are provided in the drain pipe, from a water supply hose inserted into the drain pipe from another cleaning port toward the discharge cleaning port for discharging the residue in the drain pipe. The water in the drain pipe is made to wave by the water flow to be sent out, and this wave grows into the water mass.

また前記他の清掃口から送水ホースを排水管内に挿入し、その後、送水ホースからその挿入方向に送水しながらこの送水ホースを他の清掃口方向に押し進めるものとしてある。   Further, the water supply hose is inserted into the drain pipe from the other cleaning port, and then the water supply hose is pushed in the direction of the other cleaning port while water is supplied from the water supply hose in the insertion direction.

また前記排出用清掃口から送水ホースを排水管内に挿入し、その後、送水ホースからその挿入方向とは逆向きに送水しながらこの送水ホースを排出用清掃口方向に引き寄せるものとしてある。   Further, a water supply hose is inserted into the drain pipe from the discharge cleaning port, and then the water supply hose is drawn toward the discharge cleaning port while supplying water from the water supply hose in the direction opposite to the insertion direction.

さらに前記送水ホースの先端に、水を放射状に噴射できる噴射ノズルを設けてなるものとしてある。   Further, an injection nozzle capable of injecting water radially is provided at the tip of the water supply hose.

前記流通する空気によって排水管内の水を波立たせ、この波を前記水塊に成長させるものとしてある。   The water in the drain pipe is made to wave by the circulating air, and this wave grows into the water mass.

また、横方向に配設する排水管の内部洗浄方法であって、同排水管内に、この排水管に設けてある排水管内の残留物を排出するための清掃口方向に所定の流速の空気を流通させるとともに、排水管内に水を送り込んでの水を基に排水管内に水塊を生成し、かつこの水塊によって排水管内の一部分を閉塞して前記排水管内を流通する空気の流通を遮断し、水塊前後の排水管内における気圧を高、低に変化させながら水塊を気圧が低となる前記清掃口方向に移動させるとともに、この水塊の移動により水塊後部に生じる乱水流によって排水管内の残留物を巻き上げ、この残留物を、水塊とともに移動する乱水流内に取り込んで前記清掃口方向に流して除去するものとしてある。   Further, the drain pipe is internally cleaned with a predetermined flow velocity of air in the direction of the cleaning port for discharging the residue in the drain pipe provided in the drain pipe. In addition to circulating, a water mass is generated in the drainage pipe based on the water sent to the drainage pipe, and a part of the drainage pipe is blocked by this water mass to block the flow of air flowing in the drainage pipe. In addition to moving the water mass in the direction of the cleaning port where the atmospheric pressure is low while changing the air pressure in the drain pipe before and after the water mass to high and low, the turbulent water flow generated at the rear of the water mass due to the movement of the water mass This residue is taken up into a turbulent water stream that moves together with the water mass, and flows in the direction of the cleaning port to be removed.

本発明の排水管の内部洗浄方法によれば、排水管内に水塊を高速移動させることにより、水塊後部の管内径一杯に生じる乱水流によって排水管内に堆積する残留物をこの排水管内底から引き剥すようにしているので、従来のように、排水管内に堆積する残留物を、ノズルから放射状に噴射する高圧水の管内底に向かう一部の高圧水によって引き離す方法と比して、本発明の方法は、乱水流といった非常に大なる力で排水管内の残留物を引き剥すので、残留物が比重の重い卵殻や貝殻等であっても容易かつ確実に排水管内底から除去ことができる。   According to the internal cleaning method for a drain pipe of the present invention, by moving a water mass at a high speed into the drain pipe, the residue accumulated in the drain pipe due to the turbulent water flow generated at the full inner diameter of the rear of the water mass is removed from the bottom of the drain pipe. Compared with the conventional method in which the residue accumulated in the drain pipe is separated by a part of the high pressure water directed radially from the nozzle toward the bottom of the high pressure water pipe, the present invention is separated. In this method, since the residue in the drain pipe is peeled off by a very large force such as turbulent water flow, the residue can be easily and reliably removed from the bottom of the drain pipe even if the residue is an egg shell or a shell having a high specific gravity.

また、水塊後部の管の内径一杯に生じる乱水流によって排水管内底から引き剥された残留物は、この乱水流に取り込まれかつ水塊に引かれるように移動する乱水流によって排水管に設けてある残留物を排出する清掃口方向に搬送される。
したがって、従来のように、ノズルから放射状に噴射する高圧水の管下方に向かう一部の高圧水により、一回に数十センチメートル程度押し流して搬送するものと比して、本発明の方法では、排水管内を高速移動する水塊が縮小して乱水流が消滅するまで残留物の搬送が継続でき、一回の搬送距離が数メートル程と非常に長くできる。
In addition, the residue peeled off from the bottom of the drainage pipe by the turbulent water flow that occurs across the inner diameter of the pipe at the rear of the water mass is provided in the drainage pipe by the turbulent water flow that is taken into the turbulent water flow and moves so as to be pulled by the water mass. It is conveyed in the direction of the cleaning port that discharges the remaining residue.
Therefore, as compared with the conventional case where a portion of the high-pressure water jetted radially from the nozzle is directed downwards by a portion of the high-pressure water, it is swept away by several tens of centimeters at a time. The transport of the residue can be continued until the water mass moving at high speed in the drain pipe is reduced and the turbulent water flow disappears, and the transport distance can be as long as several meters.

したがって、残留物を清掃口に搬送する時間も短くなり、排水管内を短時間で洗浄することができる。
そして、排水管内の洗浄完了は、残留物が清掃口に搬送されなくなった時点を目視検知することで事が足り、また、計器等による場合には、排水管内に挿入した圧力計の振動間隔が長くなったことで洗浄の完了を知ることができる。
すなわち従来は、作業者の感覚を頼りに洗浄の完了を決めていたが、本発明方法では排水管内の残留物が除去された時点で洗浄の完了を知ることができ、残留物が除去されているにも関わらず洗浄作業を続ける無駄や、残留物の取り残しもなく、効率の高い洗浄作業を行うことができる。
Therefore, the time for conveying the residue to the cleaning port is shortened, and the inside of the drain pipe can be cleaned in a short time.
In order to complete the cleaning of the drain pipe, it is sufficient to visually detect when the residue is no longer conveyed to the cleaning port.In the case of a meter, the vibration interval of the pressure gauge inserted in the drain pipe is sufficient. The completion of the cleaning can be known by the lengthening.
That is, in the past, the completion of the cleaning was determined depending on the operator's sense, but in the method of the present invention, the completion of the cleaning can be known when the residue in the drain pipe is removed, and the residue is removed. In spite of this, there is no waste of continuing the cleaning operation and no residue is left behind, so that an efficient cleaning operation can be performed.

また、従来では、ノズルから噴射する高圧水によって清掃口の方向に押し流している比重の重い卵殻や貝殻等の残留物が集まって排水管内に山ができてしまうと洗浄作業の作業効率が大幅に低下するが、本発明の方法は従来とは反対に、排水管内に山を生成することにより、排水管内に送水された水がこの山によって上方に波打つようになってこの波が排水管内を流れる気流によって水塊に成長するので、排水管内に堆積物の山ができるほどに水塊による洗浄が効率よく行われる。   Conventionally, if the high-pressure water jetted from the nozzles collects heavy eggshells, shells, and other residues that are swept away in the direction of the cleaning port, creating a mountain in the drain pipe greatly improves the efficiency of the cleaning operation. In contrast to the conventional method, the method of the present invention creates a mountain in the drain pipe, so that the water sent into the drain pipe undulates upward by the mountain, and this wave flows in the drain pipe. Since it grows into a water mass by the air current, washing with the water mass is performed efficiently so that a pile of sediment is formed in the drain pipe.

そして、本洗浄方法に使用する機器においても、従来用いているノズルから噴高圧水を噴射できる高圧洗浄機を使用でき、また排水管内の気流の発生と残留物の排水管内からの除去はバキューム吸引機を使用でき、そして、これらの機器は小規模用の小型軽量機器を用いることができるので、作業性もよく、また運搬の際も容易に持ち運びができ、さらに機器の保管に際しても保管場所を広く取らなくてもよく、さらには残留物の清掃口への搬送時間を短くできるので、洗浄に用いる水の量も従来よりも少なくて済み、排水管の内部洗浄に掛かるコストを大幅に低減できる。
また、本発明方法によれば排水管の内部洗浄に洗浄用の薬剤等を添加することなく水道水で行えるので、排水を洗剤等の化学薬品で汚染することもなく、環境保護に資することができる。
The equipment used in this cleaning method can also use a high-pressure washing machine that can inject high-pressure water from a conventional nozzle, and vacuum suction is used to generate airflow in the drainage pipe and remove residues from the drainage pipe. Since these machines can be small and light-sized equipment for small scales, they are easy to work with and can be easily transported. Since it does not have to be taken widely and the transport time of the residue to the cleaning port can be shortened, the amount of water used for cleaning can be reduced as compared with the conventional method, and the cost for cleaning the inside of the drain pipe can be greatly reduced. .
In addition, according to the method of the present invention, tap water can be used for cleaning the inside of the drain pipe without adding a cleaning agent, etc., so that drainage is not contaminated with chemicals such as detergents, and contributes to environmental protection. it can.

以下、本発明の排水管の内部洗浄方法を添付図面に基づいて説明する。

Hereinafter, a method for internally cleaning a drain pipe according to the present invention will be described with reference to the accompanying drawings.
In the accompanying drawings, FIG. 1 shows the case where the drain pipe internal cleaning method of the present invention is used for internal cleaning of a drainage horizontal pipe 2 for flowing the drainage of the sink to the drainage vertical main pipe 1 arranged in the vertical direction of the building. Moreover, FIGS. 2-4 is an Example at the time of using for the internal washing | cleaning of the drainage horizontal main pipe 12 connected to the lower end part of the drainage vertical main pipe 1. FIG.

図1に示すように、マンション等の建屋の各階を貫通して配設される排水縦本管1に接続する排水横管2の内部を洗浄する場合は、この排水横管2の排水上流側となるシンクのディスポーザ(図示は省略)近傍に1箇所設けてある清掃口3の蓋(図示は省略)を開け、この清掃口3から排水横管2内に、気流発生と残留物吸引除去用のバキューム吸引機(図示は省略)の吸引ホース4を挿入するとともに、管内洗浄と水塊生成用の高圧洗浄機(図示は省略)の送水ホース5を挿入し、かつ送水ホース5先端を排水縦本管1の接続部近傍の位置まで挿入する。   As shown in FIG. 1, when cleaning the inside of the drainage horizontal pipe 2 connected to the drainage main pipe 1 that is disposed through each floor of a building such as an apartment, the drainage upstream side of the drainage horizontal pipe 2 Open the lid (not shown) of the cleaning port 3 provided in the vicinity of the disposer (not shown) of the sink to be used for airflow generation and residue suction removal from the cleaning port 3 into the drainage horizontal pipe 2 The suction hose 4 of the vacuum suction machine (not shown) is inserted, the water supply hose 5 of the high-pressure washing machine (illustration omitted) for cleaning the inside of the pipe and water mass is inserted, and the tip of the water supply hose 5 is vertically drained.

図3に示す実施例は、排水横主管12に複数配設してある例えば清掃口3から残留物の吸引除去や気流吸引用のバキューム吸引機(図示は省略)の吸引ホース4を排水横主管12に挿入し、またこの清掃口3から管内洗浄と水塊生成用の高圧洗浄機(図示は省略)の送水ホース5を挿入し、かつ送水ホース5先端を清掃口3a下近傍に位置させ、さらに清掃口3aから気流発生用の送風機(図示は省略)の送風ホース13を挿入する。また、この実施形態の場合、排水横主管12内に通過させる気流は、送風ホース13から排水横主管12内に送風される空気を主にしている。   In the embodiment shown in FIG. 3, a plurality of drainage horizontal main pipes 12 are provided with, for example, a suction hose 4 of a vacuum suction machine (not shown) for sucking and removing residues and aspirating air from the cleaning port 3. 12 and the water supply hose 5 of the high-pressure washing machine (illustration omitted) for cleaning the inside of the pipe and generating water mass is inserted from the cleaning port 3, and the tip of the water supply hose 5 is positioned near the lower portion of the cleaning port 3a, Further, a blower hose 13 of a blower (not shown) for generating an air current is inserted from the cleaning port 3a. In the case of this embodiment, the airflow passed through the drainage horizontal main pipe 12 is mainly air blown into the drainage horizontal main pipe 12 from the blower hose 13.

このように、排水横主管12内に吸引ホース4、送風ホース13、送水ホース5をセットしたら、送風機、バキューム吸引機を起動して排水横主管12内に矢印方向の気流4aを発生させるとともに、高圧洗浄機を起動して送水ホース5先端に有する噴射ノズル6から洗浄水7を放射状に後方噴射させるとともに、送水ホース5を進退移動させながら送水ホース5先端に有する噴射ノズル6を適宜に送水ホース5の挿入口である清掃口3方向に引き寄せ、排水横主管12内に矢印方向の水流7aを発生させる。   Thus, when the suction hose 4, the blower hose 13, and the water supply hose 5 are set in the drainage horizontal main pipe 12, the blower and the vacuum suction machine are activated to generate the airflow 4a in the direction of the arrow in the drainage horizontal main pipe 12, The high-pressure washing machine is activated and the washing water 7 is sprayed radially backward from the jet nozzle 6 at the tip of the water supply hose 5, and the water jet hose 5 at the tip of the water feed hose 5 is appropriately moved while moving the water supply hose 5 back and forth. 5 is drawn in the direction of the cleaning port 3 which is the insertion port 5, and a water flow 7 a in the direction of the arrow is generated in the drainage horizontal main pipe 12.

また送水ホース5の進退移動が繰り返されることでまた噴射ノズル6も進退移動し、この噴射ノズル6から噴射される洗浄水7によって排水横主管12内壁に付着する汚れが適宜に洗浄され、かつ排水横主管12に堆積する卵殻や貝殻等の堆積物も清掃口3方向に運搬されて行く。また、排水横主管12内部における洗浄水7の詳しい動きは、図5に基づいて後述するが、この実施形態の場合、排水横主管12内に生成する水塊9は、送風ホース13から排水横主管12内に送風される空気の気圧によって後押しされて進む。
そして、本発明の方法で洗浄されて清掃口3に運搬されてきた排水横主管12内の残留物は、バキューム吸引機の吸引ホース4で洗浄用の水や空気とともに吸引除去される。
Further, the forward and backward movement of the water supply hose 5 is repeated, so that the spray nozzle 6 also moves forward and backward. The dirt adhering to the inner wall of the drainage horizontal main pipe 12 is appropriately cleaned by the cleaning water 7 sprayed from the spray nozzle 6, and the drainage Deposits such as eggshells and shells deposited on the horizontal main pipe 12 are also transported in the direction of the cleaning port 3. The detailed movement of the washing water 7 inside the drainage horizontal main pipe 12 will be described later with reference to FIG. 5. In this embodiment, the water mass 9 generated in the drainage horizontal main pipe 12 is discharged from the blower hose 13 to the side of the drainage. It is boosted by the pressure of the air blown into the main pipe 12 and proceeds.
The residue in the drainage horizontal main pipe 12 that has been washed by the method of the present invention and transported to the cleaning port 3 is sucked and removed together with water and air for washing by the suction hose 4 of the vacuum suction machine.

図4に示す実施例は、排水横主管12に複数配設してある例えば清掃口3から残留物吸引除去や気流発生用のバキューム吸引機(図示は省略)の吸引ホース4を排水横主管12に挿入し、また清掃口3aから管内洗浄と水塊生成用の高圧洗浄機(図示は省略)の送水ホース5を挿入し、かつ送水ホース5先端を清掃口3a下近傍に位置させる。   In the embodiment shown in FIG. 4, the drainage horizontal main pipe 12 is provided with a suction hose 4 of a vacuum suction machine (not shown) for removing and sucking residues and generating air currents from a plurality of cleaning horizontal pipes 12, for example. In addition, a water supply hose 5 of a high pressure washer (not shown) for cleaning the inside of the pipe and generating water mass is inserted from the cleaning port 3a, and the tip of the water supply hose 5 is positioned near the lower portion of the cleaning port 3a.

このように、排水横主管12内に吸引ホース4、送水ホース5をセットしたら、バキューム吸引機を起動して排水横主管12内に矢印方向の気流4aを発生させるとともに、高圧洗浄機を起動して送水ホース5先端に有する噴射ノズル6から洗浄水7を放射状に前方噴射させるとともに、送水ホース5を進退移動させながら送水ホース5先端に有する噴射ノズル6を適宜に吸引ホース4の挿入口である清掃口3方向に移動させ、排水横主管12内に矢印方向の水流7aを発生させる。   Thus, when the suction hose 4 and the water supply hose 5 are set in the drainage horizontal main pipe 12, the vacuum suction machine is activated to generate the air flow 4a in the direction of the arrow in the drainage horizontal main pipe 12, and the high pressure washer is activated. Then, the cleaning water 7 is sprayed radially forward from the spray nozzle 6 at the tip of the water supply hose 5 and the spray nozzle 6 at the tip of the water supply hose 5 is an insertion port of the suction hose 4 appropriately while moving the water supply hose 5 forward and backward. It is moved in the direction of the cleaning port 3, and a water flow 7 a in the direction of the arrow is generated in the drainage horizontal main pipe 12.

また送水ホース5の進退移動が繰り返されることでまた噴射ノズル6も進退移動し、この噴射ノズル6から噴射される洗浄水7によって排水横主管12内壁に付着する汚れが適宜に洗浄され、かつ排水横主管12に堆積する卵殻や貝殻等の堆積物も清掃口3方向に運搬されて行く。また、排水横主管12内部における洗浄水7の詳しい動きは、図5に基づいて後述する。
そして、本発明の方法で洗浄されて清掃口3に運搬されてきた排水横主管12内の残留物は、バキューム吸引機の吸引ホース4で洗浄用の水や空気とともに吸引除去される。
Further, the forward and backward movement of the water supply hose 5 is repeated, so that the spray nozzle 6 also moves forward and backward. The dirt adhering to the inner wall of the drainage horizontal main pipe 12 is appropriately cleaned by the cleaning water 7 sprayed from the spray nozzle 6, and the drainage Deposits such as eggshells and shells deposited on the horizontal main pipe 12 are also transported in the direction of the cleaning port 3. The detailed movement of the cleaning water 7 inside the drainage horizontal main pipe 12 will be described later with reference to FIG.
The residue in the drainage horizontal main pipe 12 that has been washed by the method of the present invention and transported to the cleaning port 3 is sucked and removed together with water and air for washing by the suction hose 4 of the vacuum suction machine.

そして、上述する排水横管2、排水横主管12内に流す気流4aは、管口径の大小に関係なく5m/sから15m/s程度を必要とするが、好適な流速は15m/s程度である。勿論、排水管が破損するおそれがないのであれば15m/s以上の気流を流す場合もある。   The airflow 4a flowing through the drainage horizontal pipe 2 and the drainage horizontal main pipe 12 described above requires about 5 m / s to 15 m / s regardless of the size of the pipe diameter, but a suitable flow rate is about 15 m / s. is there. Of course, if there is no possibility of damaging the drain pipe, an air flow of 15 m / s or more may flow.

また排水横管2、排水横主管12に流す気流4aの圧力すなわち気圧は、絶対値で0.5kPaから20kPaを必要とする。勿論、排水管が破損するおそれがないのであれば20kPa以上の気圧とする場合もある。   Further, the pressure of the airflow 4a flowing through the drainage horizontal pipe 2 and the drainage horizontal main pipe 12, that is, the atmospheric pressure, requires an absolute value of 0.5 kPa to 20 kPa. Of course, if there is no possibility that the drain pipe is damaged, the pressure may be 20 kPa or more.

そして、排水横管2、排水横主管12における洗浄に必要とする水流7aの水量は、管内断面積の15分の1から2分の1程度であればよいが、適量は10分の1程度がよい。   The amount of water 7a required for cleaning in the drainage horizontal pipe 2 and the drainage horizontal main pipe 12 may be about 15 to 1/2 of the cross-sectional area in the pipe, but the appropriate amount is about 1/10. Is good.

次に、排水横管2、排水横主管12内における洗浄水7の詳しい動きを図5により説明する。なお同図5では、排水管内の洗浄水7の動きを明確にするため、排水管内に挿入している送水ホース5の図示は省略している。図5では、図1に示す排水横管2を用いて説明する。   Next, detailed movement of the washing water 7 in the drainage horizontal pipe 2 and the drainage horizontal main pipe 12 will be described with reference to FIG. In FIG. 5, in order to clarify the movement of the washing water 7 in the drain pipe, the water supply hose 5 inserted in the drain pipe is not shown. In FIG. 5, it demonstrates using the drainage horizontal pipe 2 shown in FIG.

洗浄水7が送水ホース5先端に有する噴射ノズル6から噴射されて、清掃口3(図1参照)方向の水流7aが発生すると、この水流7aにより洗浄水7の水面7bが波立ち、この水面7bの波立ちはやがて図5(a)のように波8に成長し、この波8が水流7aとともに清掃口3(図1参照)方向に移動して行く。   When the cleaning water 7 is sprayed from the spray nozzle 6 at the tip of the water supply hose 5 and a water flow 7a in the direction of the cleaning port 3 (see FIG. 1) is generated, the water surface 7b of the cleaning water 7 is swollen by the water flow 7a, and the water surface 7b 5 is eventually grown into a wave 8 as shown in FIG. 5A, and this wave 8 moves in the direction of the cleaning port 3 (see FIG. 1) together with the water flow 7a.

この波8は、水流7aによって移動して行く際に図5(b)のようにさらに大なる波8に成長し、水流7aとともに、また排水横管2内を流れる気流4aに後押しされて清掃口3(図1参照)方向に移動して行く。   As the wave 8 moves by the water flow 7a, it grows into a larger wave 8 as shown in FIG. 5 (b) and is cleaned by being pushed by the air flow 4a flowing in the drainage horizontal pipe 2 together with the water flow 7a. It moves in the direction of the mouth 3 (see FIG. 1).

そして波8は、水流7a、気流4aによって清掃口3(図1参照)方向に移動して行くとともに、さらに大なる波8に成長し、やがて図5(c)のように水塊9に成長する。   Then, the wave 8 moves in the direction of the cleaning port 3 (see FIG. 1) by the water flow 7a and the air flow 4a, and further grows into a larger wave 8, and eventually grows into a water mass 9 as shown in FIG. 5C. To do.

このように波8が水塊9に成長すると、排水横管2内がこの水塊9により閉塞されて気流4aの流れが遮断され、水塊9を境に、この水塊9が進行する前方すなわち清掃口3(図1参照)方向の気圧が、バキューム吸引機(図示は省略)による排水横管2内における空気の吸引により低(低気圧)となって、水塊9が、低の気圧となった清掃口3(図1参照)方向に吸い寄せられるように移動する。   When the waves 8 grow into the water mass 9 in this way, the inside of the drainage horizontal pipe 2 is blocked by the water mass 9, the flow of the air flow 4 a is blocked, and the front of the water mass 9 advances from the water mass 9 as a boundary. That is, the air pressure in the direction of the cleaning port 3 (see FIG. 1) becomes low (low air pressure) due to the suction of air in the drainage horizontal pipe 2 by a vacuum suction device (not shown), and the water mass 9 has a low air pressure. It moves so as to be sucked in the direction of the cleaning port 3 (see FIG. 1).

そして、水塊9は吸引される空気の流速に近づくべく加速する。この水塊9が排水横管2内を移動する速度は、後述する各条件で行った実験において、排水横管2内の気流速度を10m/sに設定して行った場合に、水塊9は5m/sに加速して排水横管2内を移動し、また水塊9が消滅するまでの移動距離は15m程度になり、したがって排水横管2内の残留物11も、この水塊9が消滅するまで運搬されることになる。   Then, the water mass 9 is accelerated to approach the flow velocity of the sucked air. The speed at which the water mass 9 moves in the drainage horizontal pipe 2 is determined when the airflow velocity in the drainage horizontal pipe 2 is set to 10 m / s in experiments conducted under various conditions described later. Accelerates to 5 m / s and moves in the drainage horizontal pipe 2, and the moving distance until the water mass 9 disappears is about 15 m. Therefore, the residue 11 in the drainage horizontal pipe 2 also becomes the water mass 9. Will be transported until it disappears.

実験は、内径70mmの配管を平面コ字状に配設し、配管内に10m/sの空気を流して行った。この場合、配管内の気流圧は、無負荷(水塊9無し)の時は3kPaとなり、また有負荷(水塊9有り)の時は19kPa(絶対値)となった。   The experiment was performed by arranging a pipe having an inner diameter of 70 mm in a plane U shape and flowing air of 10 m / s into the pipe. In this case, the airflow pressure in the pipe was 3 kPa when there was no load (no water mass 9), and 19 kPa (absolute value) when there was a load (with water mass 9).

また、この加速した水塊9の後部には、図5(d)のように、乱水流10が発生し、この乱水流10は、ハイスピードカメラで撮影した映像を解析すると、水塊9後部の排水横管2内周壁側に位置する水7が順次水塊9の後部中心に向かって流れ込むように移動し、あたかも水塊9後部の水7が排水横管2内壁の鉛直方向に回転しながら水塊9を追うように移動した。   Further, as shown in FIG. 5 (d), a turbulent water flow 10 is generated at the rear part of the accelerated water mass 9, and the turbulent water flow 10 is analyzed by analyzing the video taken by the high speed camera. The water 7 located on the inner peripheral wall side of the drainage horizontal pipe 2 moves so as to sequentially flow toward the rear center of the water mass 9, and the water 7 at the rear of the water mass 9 rotates in the vertical direction of the inner wall of the drainage horizontal pipe 2. However, it moved to follow the water mass 9.

したがって、図5(e)のように、水塊9の後部に発生した乱水流10が、排水横管2内に堆積する卵殻や貝殻等の比重の重い残留物11を巻き上げるとともに、この巻き上げた残留物11を乱水流10内に取り込んで、バキューム吸引機(図示は省略)による排水横管2内における空気の吸引により推進力を得ている水塊9とともに、清掃口3(図1参照)方向に流れて行く。   Therefore, as shown in FIG. 5 (e), the turbulent water flow 10 generated at the rear of the water body 9 rolls up the heavy residue 11 such as eggshell and shells accumulated in the drainage horizontal pipe 2 and winds up this. The residue 11 is taken into the turbulent water flow 10 and the cleaning port 3 (see FIG. 1) is obtained together with the water mass 9 that has been propelled by suction of air in the drainage horizontal pipe 2 by a vacuum suction device (not shown). Flow in the direction.

そして、上述した図5(a)から(e)に示す洗浄水7の動きが、排水横管2内で繰り返され、排水横管2内壁に付着する汚れや排水横管2内に堆積する卵殻や貝殻等の比重の重い残留物11が清掃口3方向に運搬されて行く。   Then, the movement of the washing water 7 shown in FIGS. 5 (a) to 5 (e) is repeated in the drainage horizontal pipe 2, and dirt adhered to the inner wall of the drainage horizontal pipe 2 or eggshell deposited in the drainage horizontal pipe 2 Residue 11 having a high specific gravity, such as shells or shells, is transported toward the cleaning port 3.

また、図5における水塊9の生成は、排水横管2内の水流7aによって生成しているが、排水横管2内を通過する気流4aによって水塊9を生成する場合もある。この気流4aによって水塊9を生成する場合は、排水横管2内における洗浄水7の水量をある程度多くした方が、洗浄水7における水面7aの波立ちが水塊9に成長し易くなる。   Further, the water mass 9 in FIG. 5 is generated by the water flow 7a in the drainage horizontal pipe 2, but the water mass 9 may be generated by the airflow 4a passing through the drainage horizontal pipe 2. In the case where the water mass 9 is generated by the air flow 4 a, the water surface 7 a in the cleaning water 7 easily grows into the water mass 9 when the amount of the cleaning water 7 in the drainage horizontal pipe 2 is increased to some extent.

そして、前述する図3に示す実施形態の場合は、送風ホース13から排水横主管12内に送風される空気によって排水横主管12内に気流4aが生じるので、排水横管2内に生じた水塊9によりこの排水横管2内が閉塞されて気流4aの流れが遮断されると、この水塊9を境に、水塊9が進行する前方すなわち清掃口3(図1参照)方向の排水横管2内の気圧よりも、送風機(図示は省略)の送風ホース13を挿入している清掃口3a側の排水横管2内の気圧が高となるので、水塊9は、送風機から送風される空気(高の気圧)により清掃口3(図1参照)方向に後押しされて移動する。   In the case of the embodiment shown in FIG. 3 described above, since the air flow 4a is generated in the drainage horizontal main pipe 12 by the air blown into the drainage horizontal main pipe 12 from the blower hose 13, the water generated in the drainage horizontal pipe 2 is generated. When the inside of the drainage horizontal pipe 2 is blocked by the lump 9 and the flow of the air flow 4a is interrupted, the drainage in the forward direction where the water lump 9 advances, that is, in the direction of the cleaning port 3 (see FIG. 1). Since the air pressure in the drainage horizontal pipe 2 on the side of the cleaning port 3a into which the blower hose 13 of the blower (not shown) is inserted becomes higher than the pressure in the horizontal pipe 2, the water mass 9 is blown from the blower. The air is moved in the direction of the cleaning port 3 (see FIG. 1) by the air (high atmospheric pressure).
