【考案の詳細な説明】
「産業上の利用分野」
本考案は、地下水位が高いかまたは雨水の地下
浸透が緩慢な農地などに埋設される暗渠排水土管
に関する。[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to an underground drainage earthen pipe that is buried in agricultural land or the like where the groundwater level is high or rainwater permeates slowly underground.
「従来の技術」
従来、この種の暗渠排水土管として、円筒形本
体の一端にそれよりも大径な継手部を設け、この
継手部の内周面に段部を形成し、暗渠排水土管相
互の連結にあたつては、一方の土管の継手部と他
方の土管の円筒形本体の他端部とを、それらの間
に所要の間隙が形成させるように嵌合し、この間
隙を通じて水を土管内に浸入させるようにしたも
のが知られている。``Prior art'' Conventionally, this type of underdrain drainage earthen pipe was provided with a joint part with a larger diameter at one end of the cylindrical body, and a stepped part was formed on the inner peripheral surface of this joint part, so that the underdrain earthen pipes could be connected to each other. When connecting, the joint of one clay pipe and the other end of the cylindrical body of the other clay pipe are fitted so that a required gap is formed between them, and water is allowed to flow through this gap. It is known that it is allowed to infiltrate into clay pipes.
「考案が解決しようとする問題点」
しかし、これでは、他方の土管の円筒形本体の
他端開口縁が一方の土管の継手部内の段部に密接
すると、上記間隙が閉じられて水の浸入量が著し
く減少し、場合によつては水を土管内に全く導入
できなくなるという問題点があつた。``Problem that the invention attempts to solve'' However, with this method, if the opening edge of the other end of the cylindrical body of the other earthen pipe comes into close contact with the step in the joint of one earthen pipe, the gap will be closed and water will not infiltrate. There was a problem that the amount of water decreased significantly, and in some cases, it became impossible to introduce water into the clay pipes at all.
本考案は、上記従来のものを改良してこのよう
な問題点を解消しようとするものである。 The present invention is an attempt to solve these problems by improving the conventional device described above.
「問題点を解決するための手段」
本考案の暗渠排水土管は、継手部の内周面に、
その開口縁より段部にわたる複数の凸条を形成し
たことを特徴とする。"Means for solving the problem" The underdrain drainage earthen pipe of this invention has a
It is characterized in that a plurality of protrusions are formed extending from the opening edge to the stepped portion.
「作用」
従つて、一方の土管の継手部の内周面と他方の
土管の円筒形本体の他端部の外周面とは、複数の
凸条によつて常に一定の間隙を保持される。"Operation" Therefore, a constant gap is always maintained between the inner circumferential surface of the joint of one clay pipe and the outer circumferential surface of the other end of the cylindrical body of the other clay pipe by the plurality of protrusions.
「実施例」
以下に本考案の実施例を図面に基づいて説明す
る。"Embodiments" Examples of the present invention will be described below based on the drawings.
本暗渠排水土管１は、円筒形の長い本体２の一
端に、それよりも大径な短い継手部３を一体に突
設している。 The present culvert drainage earthen pipe 1 has a short joint part 3 having a larger diameter than the long cylindrical main body 2 integrally projecting from one end thereof.
継手部３は、その開口縁４に向かつて拡がる漏
斗状をなし、その内周面の基端に段部５を形成し
ている。継手部３の内周面には、その開口縁４よ
り段部５の内周縁６に至る細長い複数（例えば５
個）の凸条７が所定の位相差で一体に形成されて
いる。 The joint portion 3 has a funnel shape that widens toward the opening edge 4 thereof, and has a step portion 5 formed at the base end of its inner peripheral surface. The inner circumferential surface of the joint portion 3 has a plurality of elongated holes (for example, five
The ridges 7 are integrally formed with a predetermined phase difference.
従つて、暗渠排水土管１相互を連結した状態、
つまり一方の土管１の継手部３と他方の土管１の
本体２の他端部８とを嵌合した状態において、そ
の他端部８の開口縁９は、継手部３の内周面及び
段部５に対し５個の凸条７によつて密接を阻止さ
れ、それとの間で全周にわたり常に一定の間隙１
０を保持されるもので、従来のように開口縁９が
段部５に密接して間隙１０を閉じるというような
ことはない。 Therefore, the state in which the culvert drainage soil pipes 1 are connected to each other,
In other words, when the joint 3 of one earthen pipe 1 and the other end 8 of the main body 2 of the other earthen pipe 1 are fitted together, the opening edge 9 of the other end 8 is connected to the inner peripheral surface of the joint 3 and the stepped part. 5 are prevented from coming into close contact with each other by five protrusions 7, and there is always a constant gap 1 between them over the entire circumference.
0 is maintained, and the opening edge 9 does not come into close contact with the stepped portion 5 to close the gap 10 as in the conventional case.
「考案の効果」
以上の通り本考案の暗渠排水土管によれば、嵌
合連結した土管相互の嵌合部の間に常に一定の間
隙を保持できるため、従来のように嵌合部の密接
によつて間隙が閉じられて水の管内への浸入が阻
害されるということはない。``Effect of the invention'' As described above, according to the underdrain drainage earthen pipe of the present invention, a constant gap can always be maintained between the fitting parts of the connected earthen pipes. Therefore, the gap will not be closed and water will not be inhibited from entering the pipe.
