Description
【0001】[0001]
この考案はリブ付管に関し、特にたとえば地中に埋設される下水配管等に用い られる、リブ付管に関する。 The present invention relates to a ribbed pipe, and more particularly to a ribbed pipe used in, for example, a sewer pipe buried underground.
【0002】[0002]
従来のリブ付管では、たとえばインクジェットプリンタ等によって、本管の外 面すなわちリブとリブとの間にレベル出しのための標線を形成するようにしてい た。 In conventional ribbed pipes, for example, an inkjet printer or the like is used to form a marked line for leveling between the outer surfaces of the main pipe, that is, between the ribs.
【0003】[0003]
リブ付管に土砂が付着して標線が見えなくなった場合には、レベル出し作業時 に土砂を払い除けて標線を露出させる必要がある。ところが、リブとリブとの間 に標線が形成された従来のリブ付管では、リブがじゃまするので、管軸方向では なく周方向にしか土砂を払い除けることができないので、作業性が悪いという問 題点があった。たとえば、1スパン40〜50mのものでは、レベル出しのため に、そのような土砂の除去作業だけでも非常に長時間を要してしまう。 If the marked line cannot be seen due to the adhered sediment on the ribbed pipe, it is necessary to remove the sediment during the leveling work to expose the marked line. However, in the conventional ribbed pipe in which a marked line is formed between the ribs, the ribs hinder the removal of soil and sand only in the circumferential direction, not in the pipe axis direction, resulting in poor workability. There was a problem. For example, in the case of one span of 40 to 50 m, it takes a very long time just to remove the soil for leveling.
【0004】 それゆえに、この考案の主たる目的は、レベル出しのための作業性を向上でき る、リブ付管を提供することである。Therefore, a main object of the present invention is to provide a ribbed tube capable of improving workability for leveling.

この考案は、本管および本管の外面に形成される複数の周方向リブを備えるリ ブ付管において、複数の周方向リブの先端面に本管の管軸に対して平行に延びる 標線を形成したことを特徴とする、リブ付管である。 This invention relates to a rib-equipped pipe including a main pipe and a plurality of circumferential ribs formed on the outer surface of the main pipe, wherein the end faces of the plurality of circumferential ribs extend parallel to the pipe axis of the main pipe. The ribbed tube is characterized in that
【0006】[0006]
標線がリブの先端面に記入されるので、埋め戻しの際に標線が土砂に埋もれる ことは殆どないばかりか、仮に標線が土砂に隠されても、付着した土砂を管軸方 向に払い除けることによって、標線を簡単に露出させることができる。 Since the marked line is written on the tip surface of the rib, the marked line is rarely buried in the sediment during backfilling, and even if the marked line is hidden by the sediment, the adhered sediment is directed toward the pipe axis. It is possible to easily expose the marked line by removing it.
【0007】[0007]
この考案によれば、標線を簡単に露出させることができるので、レベル出し作 業の迅速化を図ることができる。 この考案の上述の目的,その他の目的,特徴および利点は、図面を参照して行 う以下の実施例の詳細な説明から一層明らかとなろう。 According to this invention, since the marked line can be easily exposed, the leveling operation can be speeded up. The above-mentioned objects, other objects, features and advantages of the present invention will be more apparent from the following detailed description of the embodiments with reference to the drawings.
【0008】[0008]
図1および図2を参照して、この実施例のリブ付管10は、断面略円形の本管 12を含み、本管12の外面には、管軸方向に所定間隔毎に配置される複数の周 方向リブ14が形成される。そして、各々の周方向リブ14の先端面(外周面) には、本管12の管軸に対して平行方向に延びる標線16がたとえばインクジェ ット等によって形成される。なお、標線16は、溝あるいは突起等として形成さ れてもよい。 1 and 2, a ribbed pipe 10 of this embodiment includes a main pipe 12 having a substantially circular cross section, and a plurality of main pipes 12 are arranged on the outer surface of the main pipe 12 at predetermined intervals in the pipe axial direction. Circumferential ribs 14 are formed. Then, on the tip end surface (outer peripheral surface) of each circumferential rib 14, a marked line 16 extending in a direction parallel to the tube axis of the main tube 12 is formed by, for example, an ink jet. The marked line 16 may be formed as a groove or a protrusion.
【0009】 このようなリブ付管10が、たとえば下水用管路として地中に敷設される。リ ブ付管10の敷設時には、まず、開削された敷設溝の底部にたとえば砂基礎が形 成され、この砂基礎上にリブ付管10が配置される。そして、標線16を基準と してリブ付管10のレベル出しが行われる。このとき土砂が付着して標線16が 見えなくなっている場合には、手または足等で土砂を管軸方向へ払い除けること によって標線16が露出される。レベル出し終了後、敷設溝が埋め戻される。Such a ribbed pipe 10 is laid in the ground as, for example, a sewer pipe line. When laying the ribbed pipe 10, first, for example, a sand foundation is formed at the bottom of the excavated laying groove, and the ribbed pipe 10 is placed on the sand foundation. Then, the leveling of the ribbed tube 10 is performed with reference to the marked line 16. At this time, if the sediment 16 adheres and the reference line 16 is no longer visible, the reference line 16 is exposed by wiping off the sediment with the hands or feet in the axial direction of the pipe. After completing the leveling, the laying groove is backfilled.
【0010】 この考案によれば、標線16上に土砂が付着したとしても、それを管軸方向へ 払い除けることができるので、標線16を簡単に露出させることができ、レベル 出し作業の迅速化を図ることができる。According to the present invention, even if the earth and sand adhere to the marking line 16, it can be removed in the axial direction of the pipe, so that the marking line 16 can be easily exposed and the leveling work can be performed. It is possible to speed up.
