본 고안은 유공관(有孔菅; Strainer)에 관한 것으로, 특히 유공관을 사출성형시킬수 있는 유공관을 제공하기 위한 것이다.The present invention relates to a perforated tube (有 孔 菅; strainer), in particular to provide a perforated tube that can be injection molded the perforated tube.

유공관이라 함은 관벽에 관체의 내ㆍ외부를 관통하는 다수의 구멍을 형성시켜 관벽의 구멍을 통하여 관의 내외부로 유체가 유통될 수 있게 하여서 된 것으로, 관정(管井)의 하단 취수부에 연결 매설하여 지하수를 여과 취수하는 데 흔히 사용되는 것인바, 종래에는 이러한 유공관을 제조함에 있어서 관체를 압출 성형시킨 후, 관체를 회전톱 등으로 길이방향으로 절삭 천공하여 통공을 형성시키고, 연결부위에 스테인리스 관체를 덧씌우고 리베트등으로 연결부위를 결합하여 형성시켜 왔다. 그런데 이와같이 관체를 회전톱 등으로 천공하게 되면 구멍의 위치가 일정하지 않게 되어 천공괸 부위에 따라서는 취약부위가 발생할 수 있어 구멍을 촘촘히 형성시킬 수 없으므로 취수의 효율이 낮은 결점이 있으며, 회전톱으로 절삭한 길이 방향의 구멍이 깔끔치 않음은 물론 절삭작업시 길이방향으로 관체가 잘 깨어지는 관성이 있어 제품의 품위를 저하시키는 결점이 있었던 것이다. 그리고 인체에 무해한 폴리에치렌 등으로 관체를 형성시킬 경우 포리에치렌은 용융점이 낮아 이를 회전톱날로 절삭하려면 톱날에 포리에치렌이 엉겨붙어 절삭작업이 곤란하므로 부득이 인체에 유해한 PVC로 관체를 성형시키지 않을 수 없는 결점이 있었던 것이다.Perforated pipes are formed by forming a plurality of holes penetrating the inside and outside of the pipe to allow fluid to flow into and out of the pipe through the holes in the pipe wall. It is commonly used to filter the groundwater by the bar, conventionally in the manufacture of such a perforated pipe by extrusion molding the tube, the tube is cut in the longitudinal direction with a rotary saw or the like to form a through hole, the stainless steel tube on the connection part Overlaying and has been formed by combining the connecting parts such as rivets. However, when the tube is punched with a rotary saw, the position of the hole becomes inconsistent, and a weak spot may occur depending on the punched-out area, so that the hole cannot be formed densely. Not only was the hole in the longitudinal direction cut neat but also the inertia of the tubular body well broken in the longitudinal direction during the cutting operation, there was a defect that degrades the product quality. In case of forming the tubular body with poly ethylene, which is harmless to the human body, the porridge styrene has low melting point. There was an inevitable defect.

이에 본 고안은 유공관을 사출 성형하므로서 유공관에 형성시키는 구멍의 크기와 위치를 일정하게 하여 기대하는 바 대로의 취수 효율을 얻을 수 있도록 하며, 사출 성형시키는 물질의 제한을 극복하므로서 깨어지지도 않고 인체에 무해한 폴리에치렌으로도 이를 성형시킬 수 있게 하며, 사출 성형시킨 단위 유공관을 공지의 결합수단으로 다수개 연결할 수 있게 하므로서 필요로 하는 길이의 유공관을 얻을 수 있도록 한 것인 바, 이와 같은 본 고안을 첨부된 도면에 의하여 설명하면 다음과 같다.In this regard, the present invention makes it possible to obtain the water-intake efficiency as expected by making the hole size formed in the hole tube constant by injection molding the hole tube, and it is harmless to the human body without breaking by overcoming the limitation of the injection molding material. It is also possible to mold it with poly ethylene, and it is possible to obtain a plurality of perforated pipes of the required length by connecting a plurality of injection molded unit perforated pipes by known coupling means, the present invention is attached to this Referring to the drawings as follows.

유공관은 일반적으로 그 직경이 75∼300㎜ 정도로 대구경일 뿐만 아니라 그 단위 유공관의 길이가 4m 정도로 길어서 일반적인 사출법에 의하여서는 이를 사출 성형시키는 것이 불가능하다.In general, the perforated pipes are not only large diameters of about 75 to 300 mm in diameter, but also the length of the unit perforating pipes are about 4 m long, so that injection molding is impossible by a general injection method.

이에 본 고안은 사출 금형으로 약 25∼50㎝정도 길이의 단위유공관(1)을 사출 성형시킨 후 성형된 다수개의 단위유공관(1)을 공지의 결합수단(2)으로 연결하여 소요 길이의 유공관을 얻을 수 있게 하였다. 이와 같이 단위유공관(1)을 사출 성형시킬 수 있도록 하기 위하여, 본 고안은 단위유공관(1)에 통공(11)을 형성시킴에 있어서 통공(11)을 형성시키는 벽면(11-1, 11-2, 11-3)의 내외방향(가)와 통공(11')을 형성시키는 벽면(11-4, 11-5, 11-6)의 내외방향이 첨부된 도면 제2도에 도시된 바와 같이 서로 직교되게 형성시켰다. 그리하므로서 첨부된 도면 제4도에 도시된 바와 같이 단위유공관(1)을 성형시키는 금형을 상하 좌우안팎으로 분리시킬 수 있게 한다.Therefore, the present invention connects a plurality of unit perforated tubes (1) formed by injection molding a unit perforated tube (1) having a length of about 25 to 50 cm with an injection mold and connects the perforated tube having a required length by a known coupling means (2). To get it. In order to enable injection molding of the unit perforated tube 1 as described above, the present invention forms wall through holes 11 in the unit perforated pipe 1 to form the through holes 11. 11-3, the inner and outer directions (a) and the inner and outer directions of the wall surfaces (11-4, 11-5, 11-6) forming the through holes 11 'are shown as shown in FIG. Formed orthogonally. Thus, as shown in Figure 4 of the accompanying drawings it is possible to separate the mold for forming the unit perforated pipe (1) up and down and left and right.

사출성형된 단위유공관(1)과 다른 단위유공관(1)의 연결을 용이하게 하기 위하여서는 유공관(1)의 양단에 적절한 결합수단이 마련되어야 한다. 이러한 결합수단으로서는 공지의 결합수단에서 보는바와같이 단위유공관)의 양단에 형성시키는 암수결합부(12,13)와 결합된 암수결합부(12,13)를 고정시키는 리베트(14)로 형성시키는 것이 바람직하다. 암수결합부(12,13)를 리베트(14)로 연결시킴에 있어서는 리베트(14)의 머리가 관체의 외면 밖으로 돌출되지 아니하도록 첨부된 도면 제3도에 도시된 바와 같이 수연결부(13)의 외벽에 요함부(15)를 형성시키는 것이 바람직하다.In order to facilitate the connection of the injection molded unit perforated pipe (1) and the other unit perforated pipe (1), appropriate coupling means should be provided at both ends of the perforated pipe (1). Such coupling means may be formed of a rivet 14 for fixing the female and female coupling portions 12 and 13 coupled to the female and female coupling portions 12 and 13 formed at both ends of the unit perforated pipe as shown in the known coupling means. desirable. In connecting the male and female coupling parts 12 and 13 to the rivet 14, the head of the rivet 14 does not protrude out of the outer surface of the tube, as shown in FIG. It is preferable to form the recess 15 in the outer wall.

이와 같이 구성된 본 고안은 성형된 관체에 별도의 천공작업을 가할 필요가 없게 되어 생산비를 절감할 수 있고, 단위 시간당 생산량을 증대시킬 수 있게 되며, 특히 종래에는 유공관에 형성시키는 구멍의 크기를 회전톱날의 두께 이하의 폭으로 형성시킬 수가 없어 구멍을 통하여 불순물이 유입될 염려가 있었으나, 본 고안은 구멍의 폭을 최소화 할 수 있으므로 불순물의 유입을 방지하면서도 구멍을 조밀하게 형성시킬 수 있어 개공률을 향상시켜 취수효율을 높일 수 있으며, 구멍주위 부분을 깔끔하게 형성시킬 수 있어 유공관의 품질향상에 크게 기여할 수 있을 뿐 아니라, 유공관을 인체에 해가 없는 폴리에치렌 등으로 형성시킬 수 있어 취수시의 오염을 방지할 수 있는 효과가 있다.The present invention configured as described above does not need to apply a separate punching work to the molded tube to reduce the production cost, and to increase the output per unit time, and in particular, the size of the hole formed in the perforated pipe in the conventional rotary saw blade Although it could not be formed to a width less than the thickness of the impurity could be introduced through the hole, but the present design can minimize the width of the hole to prevent the inflow of impurities while forming the hole densely improved the opening rate It can increase the water intake efficiency, and it can make the periphery of the hole neatly, which can greatly contribute to the improvement of the quality of the perforated pipes, and the perforated pipes can be formed with poly ethylene, which is harmless to the human body. There is an effect that can be prevented.
