Abstract

PURPOSE: A connection method of a soil pipe using an electro-fusion joint pipe is provided to rapidly perform a connection of a soil pipe because the rest half part of an electro-fusion joint pipe is fused with the other end in the field in the state that half part of the electro-fusion joint pipe is fixed. CONSTITUTION: A connection method of a soil pipe using an electro-fusion joint pipe(10) is as follows. Half foam sheet(12) of an electro-fusion joint pipe is inserted into the end part of a pipe(18) and a supporting pipe(50) is inserted into the rest half part of the foam sheet so that a fixing bane is joined. A electric heating wire panel corresponding to the half part of the foam sheet is heated so that the half part of the foam sheet is thermally fused in one end part of the pipe. The fixing band is released and the supporting pipe is eliminated. Other end part of the other pipe is inserted into the rest half part of foam sheet so that the fixing band is joined again. A heating wire panel corresponding to the rest part of the foam sheet is heated so that the rest half of foam sheet is thermally fused in the other end part of the pipe.

Description

전기융착이음관을 이용한 오수관의 연결방법 {METHOD OF CONNECTING SEWER PIPES USING ELECTRO-FUSION CONNECTOR}How to connect sewage pipe using electric fusion joint pipe {METHOD OF CONNECTING SEWER PIPES USING ELECTRO-FUSION CONNECTOR}

본 발명은 전기융착이음관을 이용한 오수관의 연결방법에 관한 것으로, 특히 단부와 단부가 접합되어 연결되는 두 오수관의 이러한 연결단부상에 권취되어 전기융착방식으로 고정되는 오수관 연결용 전기융착이음관을 이용하여 오수관을 연결하는 연결방법에 관한 것이다.The present invention relates to a method of connecting sewage pipes using an electric fusion joint, and in particular, an electric fusion joint for connecting sewage pipes, which is wound on the connection end of two sewage pipes which are connected to each other by end and is fixed in an electric fusion method. It relates to a connection method for connecting the sewage pipe by using.

일반적으로 지중에 매설되는 오수관(또는 우수관을 포함할 수 있다)은 재질이 폴리에틸렌(PE) 또는 폴리프로필렌(PP)이고 외면이 평활하며 단면형태가 솔리드형 단면이거나 중간에 채널형 공간을 갖는 이중벽관 또는 삼중벽관의 파이프로 되어 있으며, 일정한 길이의 단위 오수관을 이들 오수관의 매설지 구거에 차례로 배열하고 이들 오수관의 단부와 단부를 맞대어 연결하며 이러한 연결단부상에 이음관을 연결고정하여 오수관이 접합단부에서 누수없이 연속적으로 연결될 수 있도록 한다. Generally, sewage pipes (or may include rain pipes) buried in the ground are double-walled pipes made of polyethylene (PE) or polypropylene (PP), having a smooth outer surface, and having a solid cross section or a channel space in the middle. Or, it is made of triple wall pipes, and the unit sewage pipes of a certain length are arranged in order to bury the sewage pipes of these sewage pipes, and the ends and ends of these sewage pipes are connected to each other, and the sewer pipes are connected and fixed on the connection ends. Allows to be connected continuously without leakage.

오수관용 파이프는 오수관으로 설치될 때 인접한 파이프의 단부와 단부를 맞댄 다음 이들 파이프 연결단부를 전기융착으로 누수없이 밀폐연결하는 것이 알려져 있다. 그 하나의 예로서는 파이프 연결단부의 주위를 충분히 감쌀 수 있는 폴리에틸렌 재질의 시이트의 내면에 전기발열체를 얕게 매입되게 부착시킨 것이 있다. 이러한 전기융착용 시이트는 파이프 연결단부에 그 내면측이 밀착되게 권취한 다음 고정밴드 등으로 고정시킨 상태에서 전원을 인가하여 전기발열체의 발열에 의하여 파이프의 표면 일부와 시이트 내면의 일부가 용융되어 서로 접합되고 냉각후에는 누수없이 밀폐결합되도록 한다. 그러나, 이러한 전기융착용 시이트는 전기발열체의 발열에 의하여 파이프의 표면 일부와 시이트 내면의 일부가 용융되어 접합이 이루어지기는 하나 이들의 용융후 냉각시에 부분적으로 체적수축이 일어나 연결될 두 파이프의 연결단부가 완벽하게 밀폐되지 못하는 문제점이 있다.It is known that sewage pipes, when installed as sewage pipes, face to end of adjacent pipes and then connect these pipe connection ends without leakage by electrofusion. One example of this is that the electric heating element is attached to the inner surface of the sheet of polyethylene that can sufficiently wrap around the pipe connecting end so as to be shallowly embedded. The sheet for electrical fusion is wound on the inner side of the pipe to the pipe connecting end and then applied with power in a state of being fixed with a fixing band, so that a part of the surface of the pipe and a portion of the inner surface of the sheet are melted by the heat of the electric heating element. After being joined and cooled, they should be hermetically sealed without leakage. However, the sheet for the electrofusion is joined by melting part of the surface of the pipe and part of the inner surface of the sheet by heat generation of the electric heating element, but the volume of shrinkage occurs during cooling after the melting of the two pipes to be connected. There is a problem that the end is not completely sealed.

본원 출원인의 실용신안등록 제0402687호 및 실용신안등록 제0440350호에는 파이프 연결단부에 발포융착되는 발포시이트가 소개되고 있다. 이들 특허문헌에 소개된 발포시이트는 시이트 자체에 발포성분이 혼합되어 있고 시이트 내부에 전열선이 매입되어 있다. 이러한 발포시이트는 그 외면에 중첩하여 사용되는 지지시이트와 함께 연결되는 두 파이프의 연결단부상에 권취되고 그 외부에 고정밴드가 채워진 상태에서 전원이 인가될 때 전열선이 발열하면서 발포시이트를 용융시킴과 동시에 용융물을 발포시킴으로서 파이프의 연결단부와 지지시이트 사이가 발포되는 용융물에 의하여 충만된 상태로 융착되어 완벽한 밀폐가 이루어질 수 있도록 한다. 연결되는 파이프 연결단부에 발포융착되는 발포시이트가 소개된 실용신안등록 제0402687호에서는 내부의 전열선이 발포시이트의 전폭에 걸쳐 지그재그 형태로 매입되어 있는 반면에, 실용신안등록 제0440350호에는 발포시이트내에 매입되는 전열선이 두 그룹의 전열선패널로 나누어져 중앙부분을 남기고 발포시이트의 길이방향으로 배치되어 있다.Utility Model Registration No. 04288787 and Utility Model Registration No. 0440350 of the present applicant introduce a foam sheet which is fused and foamed to a pipe connecting end. In the foamed sheet introduced in these patent documents, the foaming component is mixed in the sheet itself, and a heating wire is embedded in the sheet. The foam sheet is wound on the connecting end of two pipes connected together with the support sheet used to overlap the outer surface, and when the power is applied while the fixing band is filled therein, the heating wire generates heat and melts the foam sheet. At the same time, by foaming the melt, the connection between the connecting end of the pipe and the support sheet is fused in a filled state by the foamed melt so that a perfect seal can be achieved. In Utility Model Registration No. 042487, which introduces a foam sheet which is foamed and fused at the pipe connecting end, the internal heating wire is embedded in a zigzag form over the entire width of the foam sheet. The embedded heating wire is divided into two groups of heating wire panels, which are arranged in the longitudinal direction of the foam sheet, leaving a central part.

두 인접한 파이프의 연결단부상에 권취되어 사용되는 발포시이트는 이러한 발포시이트가 용융 및 발포되는 과정에서 두 파이프의 연결단부에 인접한 파이프의 표면부분에 사이의 발포융착되는 것이 요구된다. 한편, 연결되어야 하는 두 파이프의 연결단부는 이들을 가능한 한 근접하여 접속시킨다 하여도 이들 대응하는 연결단부 사이에는 간극이 남아 있게 마련이다. 두 파이프의 연결단부상에 권취된 발포시이트를 용융 및 발포시키는 과정에서 발포용융물이 상기 간극을 통하여 파이프의 내부로 진출하여 응고된다. 이와 같이 파이프의 내면으로부터 내측으로 진출하여 응고된 응고물은 파이프내를 흐르게 되는 유체의 유동에 대하여 저항을 일으키는 문제점이 된다. The foam sheet used to be wound on the connecting ends of two adjacent pipes is required to be foam fused between the surface portions of the pipes adjacent to the connecting ends of the two pipes in the course of melting and foaming of the foam sheets. On the other hand, even if the connecting ends of the two pipes to be connected are connected as closely as possible, a gap remains between these corresponding connecting ends. In the process of melting and foaming the foam sheet wound on the connecting end of the two pipes, the molten foam is solidified by advancing into the pipe through the gap. In this way, the coagulated product advancing inward from the inner surface of the pipe becomes a problem of causing resistance to the flow of fluid flowing through the pipe.

이러한 관점에서, 실용신안등록 제0402687호에 소개된 발포시이트의 경우 내부의 전열선이 발포시이트의 전폭에 걸쳐 지그재그 형태로 전개되어 있으므로 이를 사용하여 두 파이프의 연결단부를 연결할 때 두 파이프의 연결단부 사이에 해당하는 발포시이트의 중앙축선부분에서도 용융 및 발포가 일어나 발포용융물이 두 파이프 연결단부 사이의 간극으로 파이프내로 진출하여 응고됨으로서 상기 언급된 바와 같은 응고물을 생성할 수 있다.In view of this, in the case of the foam sheet introduced in Utility Model Registration No. 004087, the inner heating wire is developed in a zigzag form over the entire width of the foam sheet. Melting and foaming also occur in the central axis portion of the foam sheet corresponding to the foamed molten material can be solidified by advancing into the pipe into the gap between the two pipe connection end to produce a solidified product as mentioned above.

그러나, 전열선이 두 그룹의 전열선패널로 나누어져 발포시이트의 길이방향으로 배치된 것이 소개된 실용신안등록 제0440350호의 경우에 있어서는 두 파이프의 연결단부상에 권취되었을 때 두 파이프의 연결단부 사이에 놓이는 발포시이트의 중앙축선부분에 전열선이 배치되어 있지 않아 이러한 부위에서는 용융발포가 전혀 이루어지지 않거나 또는 거의 이루어지지 않으므로 발포용융물이 생성되지 않아 두 파이프의 연결단부 사이의 간극을 통하여 파이프의 내부로 용융물이 진출하여 응고물을 형성하지 않는다.However, in the case of Utility Model Registration No. 0440350, in which the heating wire is divided into two groups of heating wire panels and arranged in the longitudinal direction of the foam sheet, it is placed between the connecting ends of the two pipes when wound on the connecting ends of the two pipes. Since no heating wire is placed at the central axis of the foam sheet, no melt foaming is made or almost no foaming melt is formed in these areas. Thus, no melted foam is produced, and the melt is introduced into the pipe through the gap between the connecting ends of the two pipes. It does not enter and form a coagulum.

응고물이 형성되지 않는 잇점이 있음에도 불구하고, 상기 실용신안등록 제0440350호에 소개된 발포시이트로서 전열선이 두 그룹의 전열선패널로 나누어져 발포시이트는 이를 두 파이프의 연결단부상에 권취하였을 때 이러한 전열선패널에 전원을 인가하는 경우 두 파이프의 연결단부에 해당하는 발포시이트의 길이방향 중간부분은 용융되어 융착되는 기능을 발휘하지 못하므로 이러한 중간부분을 통한 누수가 일어날 수 있는 문제점을 안고 있다. 발포시이트를 두 파이프의 연결단부상에 권취하였을 때 발포시이트의 단부부분이 중첩되므로 중첩된 부분의 전열선패널이 이중으로 중첩되어 전원인가시에 이러한 중첩부분이 과열되는 현상을 보일 수 있다. 물론 이러한 점을 감안하여 중첩부분의 전열선 간격을 더 넓게 함으로서 중첩부분의 과열현상을 해소하도록 하는 것이 알려져 있다.Although there is an advantage that no coagulum is formed, the foam sheet introduced in Utility Model Registration No. 0440350 is divided into two groups of heating panel, and the foam sheet is wound on the connection end of the two pipes. When power is applied to the heating wire panel, the longitudinal middle portion of the foam sheet corresponding to the connection end of the two pipes does not have a function of melting and fusion, thereby causing a problem of leakage through the middle portion. When the foam sheet is wound on the connecting end of the two pipes, the end portions of the foam sheet overlap, so that the heating wire panels of the overlapped portions may overlap each other, such that the overlapped portion may overheat when the power is applied. Of course, in view of this point, it is known to widen the heating wire spacing of the overlapping portion to solve the overheating phenomenon of the overlapping portion.

한편, 상기 언급된 두 특허문헌의 발포융착시이트를 포함하는 종래의 전기융착용 시이트 또는 전기발포융착 시이트를 이용하여 오수관 또는 우수관을 구성하는 두 파이프의 연결단부를 연결하기 위한 전기융착이음관은 전형적으로 오수관 파이프가 매설되는 매설지 구거와 같은 매설현장에서 두 파이프의 단부를 연결하기 위하여 사용된다. 오수관을 구성하는 두 파이프의 연결단부를 매설현장에서 전기융착이음관으로 연결하는 작업은 매우 번거럽고 작업시간이 많이 소요되는 문제점을 안고 있다. 특히 매설현장은 하절기와 동절기의 심한 기온차와 같은 일기상황에 노출되어 있어 전기융착이음관에 인가하는 전압 또는 전류의 공급조건이 일기상황에 따라서 달라질 수밖에 없다. 이러한 변화는 오수관 파이프의 연결단부를 전체적으로 균일하고 완벽하게 연결하도록 하는데 큰 제약을 준다. 지중에 매설된 오수관의 연결단부가 볼완전하게 연결되어 누수가 있는 경우 환경오염이나 배수저항 등의 문제점이 발생하여 재시공이 요구될 수 있다.On the other hand, by using the conventional fusion sheet or the electro-foam fusion sheet including the foamed fusion sheet of the two patent documents mentioned above, the electrofusion joint pipe for connecting the connecting end of the two pipes constituting the sewage pipe or rain pipe is typical This is used to connect the ends of two pipes in a burial site, such as a burial site where the sewage pipes are buried. Connecting the connecting ends of the two pipes constituting the sewage pipes from the buried site to the electric fusion joint pipe is very cumbersome and takes a long time. In particular, the burial site is exposed to weather conditions such as severe temperature differences in summer and winter, so the supply conditions of voltage or current applied to the electric fusion joint pipe are inevitably changed depending on the weather conditions. This change places great constraints on the overall uniform and complete connection of the sewer pipe connections. If the connecting end of the sewage pipe buried underground is completely connected and there is a leak, problems such as environmental pollution or drainage resistance may occur and may require reconstruction.

본 발명에 있어서는 종래의 이러한 문제점을 감안하여 창안한 것으로, 본 발명의 목적은 기본적으로는 단부와 단부가 접합되어 연결되는 두 오수관의 이러한 연결단부상에 권취되어 전기융착방식으로 고정되는 오수관 연결용 전기융착이음관을 이용하여 오수관을 연결하는 방법을 제공하는데 있다.In the present invention, the invention was made in view of such a conventional problem, and an object of the present invention is basically for connecting a sewage pipe which is wound on the connection end of two sewage pipes which are joined to and connected to each other and fixed in an electrofusion method.

본 발명의 또 다른 목적은 오수관 파이프의 제공자 작업장에서 오수관 파이프의 일측단부에 전기융착이음관의 일부분, 예를 들어 전기융착이음관의 반부분만을 융착하여 고정시킨 상태에서 오수관 매설지의 현장에서 오수관 파이프의 타측단부에 전기융착이음관의 나머지 반부분을 융착시켜 두 파이프의 연결단부를 연결할 수 있도록 일측단부에 전기융착이음관의 반부분이 융착연결된 오수관 파이프를 제공하는데 있다. 이는 오수관 매설지의 현장에서 오수관 연결작업이 신속히 이루어질 수 있도록 한다. It is still another object of the present invention to provide sewage pipes in the field of sewage pipes in a state in which only a part of the electric fusion joint pipes, for example, a half of the electric fusion joint pipes, is fused and fixed at one end of the sewage pipe pipe in the provider workshop of the sewage pipe pipes. It is to provide a sewage pipe pipe in which the other half of the electric fusion joint pipe is fusion-spliced at one end so that the other half of the electric fusion joint pipe is fused to the other end of the joint. This makes it possible to quickly connect the sewage pipe at the site of the sewage pipe buried site.

이를 위하여, 본 발명에 있어서는 지중에 매설되는 적어도 두개의 오수관 파이프의 연결단부를 연결하기 위한 전기융착이음관이 내면으로부터 발포시이트, 지지시이트, 고정밴드로 구성되고, 상기 발포시이트가 발포제를 포함하는 시이트재 사이에 길이방향의 중간부분을 두고 양측으로 나란히 두개의 전열선패널이 배치되어 구성되며, 상기 전열선패널이 발포시이트가 연결될 두 파이프의 연결단부상에 권취될 때 상기 발포시이트의 일측단부에 중첩되는 타측단부에 넓은 간격을 갖는 광폭패널부분을 가지고, 중간부분의 경계를 이루는 일측 광폭패널부분의 변부가 중간부분을 지나 타측 광폭패널부분의 대응하는 변부에 좁은 간격을 두고 근접하게 배치된 전기융착이음관을 이용한다.To this end, in the present invention, the electrofusion joint pipe for connecting the connection ends of at least two sewage pipe pipes buried in the ground is composed of a foam sheet, a support sheet, a fixing band from the inner surface, the foam sheet comprises a foaming agent Two heating wire panels are arranged side by side on both sides with a middle portion in the longitudinal direction between sheet materials, and overlapped at one end of the foam sheet when the heating wire panels are wound on the connecting ends of the two pipes to which the foam sheets are to be connected.

지중에 매설되는 오수관, 또는 우수관의 연결용으로 사용되는 전기융착이음관(10)은 발포시이트(12), 지지시이트(14)와, 고정밴드(16)로 구성된다. 본 발명에 따라서 이러한 전기융착이음관(10)은 이후 상세히 설명되는 바와 같이 예를 들어 오수관으로 사용되는 두 파이프(18)(18')의 연결단부를 누수없이 연결하기 위하여 사용된다.The electrofusion joint pipe 10 used for connecting sewage pipes or rainwater pipes embedded in the ground is composed of a foam sheet 12, a support sheet 14, and a fixing band 16.

발포시이트Foam Sheet (12)(12)

발포시이트(12)는 주재료인 메탈로센 폴리에틸렌에 발포제로서 아조디키본아마이드가 혼합되어 시이트재(22)(24)로 제조되고, 이들 시이트재(22)(24) 사이에 이들 시이트재의 길이방향으로 나란히 두개의 전열선패널(26)(28)을 배치하고 시이트재(22)(24)를 합체하여 구성된다. 이러한 전열선패널(26)(28)은 본원 출원인의 등록실용신안 제0440350호에 소개된 발포시이트의 내부에 배치되는 전열선패널과 같이 피복전열선이 직물지에 지그재그로 직조하여 구성된 것이다. 이들 전열선패널(26)(28)은 이들을 구성하기 위하여 지그재그로 직조되는 피복전열선(30)으로 구성된다. 여기에서 지그재그형태로 배치되는 피복전열선(30)의 간격을 "t1"로 표시하였다. 한편, 전열선패널(26)(28)은 발포시이트(12)의 길이방향 축선(L)에 대하여 양측에 일정한 간격(d1)을 두고 배치된다. 따라서, 전열선패널(26)(28) 사이에는 전열선이 없는 간격 d1 의 중간부분(27)이 형성된다.The foamed sheet 12 is made of sheet materials 22 and 24 by mixing azo dikibonamide as a foaming agent with metallocene polyethylene as a main material, and the lengthwise direction of these sheet materials between these sheet materials 22 and 24. The two heating wire panels 26 and 28 are arranged side by side, and the sheet materials 22 and 24 are coalesced. Such heating wire panels 26 and 28 are constructed by zigzag weaving coated heating wires in a woven paper, such as heating wire panels disposed inside the foam sheets introduced in the Applicant's Utility Model No. 0440350. These heating wire panels 26 and 28 are comprised by the coating heating wire 30 which is zigzag-woven in order to comprise these. Here, the space | interval of the coating heating wire 30 arrange | positioned in zigzag form was represented by "t1". On the other hand, the heating wire panels 26 and 28 are arranged at regular intervals d1 on both sides with respect to the longitudinal axis L of the foam sheet 12. Therefore, the middle part 27 of the space | interval d1 without a heating wire is formed between heating wire panels 26 and 28. As shown in FIG.

이러한 발포시이트(12)의 각 전열선패널(26)(28)을 구성하는 피복전열선(30)은 발포시이트(12)이 양단에서 외측으로 각각 도선(32)(32')이 연장되어 전원에 연결될 수 있게 되어 있다. 또한 각 전열선패널(26)(28)의 위치에서 온도의 측정이 이루어질 수 있도록 하는 온도센서(34)가 배치되고 그 도선(36)은 온도감지기(도시하지 않았음)에 연결되어 도선(32)(32')에 연결되는 전원장치(역시 도시하지 않았음)를 제어할 수 있도록 한다.The coated heating wires 30 constituting each of the heating wire panels 26 and 28 of the foam sheet 12 may be connected to a power source by extending the conductive wires 32 and 32 'from both ends to the outside. It is supposed to be. In addition, a temperature sensor 34 for arranging the temperature at each position of the heating wire panels 26 and 28 is disposed, and the conductive wire 36 is connected to a temperature sensor (not shown) to connect the conductive wire 32. Allows control of a power supply (also not shown) connected to the 32 '.

발포시이트(12)는 연결될 두 파이프(18)(18')의 연결단부상에 권취될 때 그 일측단부(12a)가 타측단부(12b)에 중첩된다. 이와 같이 발포시이트(12)가 중첩되는 부분에서는 피복전열선(30)의 배치량이 배가되어 발열량이 커서 과열이 될 수 있다. 이를 방지하기 위하여, 발포시이트(12)의 일측단부(12a)에 대하여 상측으로 중첩되어 덮이는 타측단부(12b)내에 배치되는 피복전열선(30)의 간격(t2)을 다른 부위의 피복전열선(30)의 간격(t1) 보다 넓게 하여 이 부분에서 발열량이 낮도록 한다. 여기에서, 발포시이트(12)의 타측부분(12b)에 배열된 전열선패널은 다른 부분의 전열선패널(26)(28)의 피복전열선(30)의 간격(t1) 보다 넓은 간격(t2)을 갖는 광폭패널부분(26')(28')이라 할 수 있다.When the foam sheet 12 is wound on the connecting end of the two pipes 18 and 18 'to be connected, one end 12a thereof overlaps the other end 12b. In this way, in the overlapping portion of the foam sheet 12, the arrangement amount of the coated heating wire 30 is doubled, and the heat generation amount may be large, resulting in overheating. In order to prevent this, the spacing t2 of the coated heating wire 30 disposed in the other end portion 12b overlapped with the upper side with respect to one side end portion 12a of the foam sheet 12 is covered with the other portion of the coated heating wire ( It is made wider than the space | interval t1 of 30), and it makes low heat generation in this part. Here, the heating wire panel arranged on the other side portion 12b of the foam sheet 12 has a wider space t2 than the space t1 of the coated heating wire 30 of the heating wire panels 26 and 28 of the other portion. It may be referred to as the wide panel portions 26 'and 28'.

한편, 발포시이트(12)에 배치되는 전열선패널(26)(28)은 상기 언급된 바와 같이 발포시이트(12)의 길이방향 축선(L)에 대하여 양측에 일정한 간격 d1 의 중간부분(27)을 두고 배치된다. 이와 같이, 발포시이트(12)에 배치되는 전열선패널(26)(28)의 간격(d1)을 일정하게 두는 이유는 이러한 중간부분(27)이 연결될 두 파이프(18)(18')의 연결단부 사이의 간극에 놓이도록 하여 이러한 중간부분(27)이 용융발포되지 않으므로서 두 파이프(18)(18')의 연결단부가 부분적으로 용융되는 것을 방지하고 이러한 연결단부 사이의 간극으로 용융물이 침투되어 응고되는 경우가 방지될 수 있도록 하는 것이다.On the other hand, the heating wire panels 26 and 28 disposed on the foam sheet 12 have the intermediate portions 27 at regular intervals d1 on both sides with respect to the longitudinal axis L of the foam sheet 12 as mentioned above. Placed and placed. As such, the reason why the distance d1 of the heating wire panels 26 and 28 arranged in the foam sheet 12 is kept constant is that the connection ends of the two pipes 18 and 18 'to which the intermediate portion 27 is to be connected. The intermediate portion 27 is not melt-foamed so that the connecting ends of the two pipes 18 and 18 'are partially melted and the melt penetrates into the gap between these connecting ends. It is to prevent the case of solidification.

그러나, 도 4에 상세히 도시된 바와 같이, 발포시이트(12)에서 일측단부(12a)에 중첩되는 타측단부(12b)내에 배치되는 광폭패널부분(26')(28') 부분은 발포시이트(12)를 연결될 두 파이프(18)(18')의 연결단부상에 권취하여 고정할 때 발포시이트(12)의 일측단부(12a)에 중첩되는 타측단부(12b)가 그 중첩부분의 중간부분(27)의 영역을 포함하여 전체에서 발포시이트(12)의 일측단부(12a)에 확고하게 융착될 수 있어야 한다. 이를 위하여, 본 발명에 있어서는 중간부분(27)의 경계를 이루는 일측 광폭패널부분(26')의 변부를 길이방향 축선(L)을 지나 타측 광폭패널부분(28')의 대응하는 변부에 간격 d1 보다 좁은 간격 d2을 두고 근접하여 배치되도록 함으로서 발포시이트(12)의 일측단부(12a)에 중첩되는 타측단부(12b)가 그 중첩부분의 중간부분(27)의 영역을 포함하여 전체에서 발포시이트(12)의 일측단부(12a)에 확고하게 융착되어 융착작용이 일어나지 않은 중간부분(27)을 따라 누수가 일어나는 것을 방지할 수 있다.However, as shown in detail in FIG. 4, the portion of the wide panel portion 26 ′ and 28 ′ disposed in the other end portion 12 b overlapping the one end 12 a in the foam sheet 12 is the foam sheet 12. ) Is wound on the connecting end of the two pipes 18 and 18 'to be connected, and the other end 12b overlapping the one end 12a of the foam sheet 12 has an intermediate portion 27 of the overlapping portion. It should be able to be firmly fused to one end 12a of the foam sheet 12 in its entirety, including the area of ()).

본 발명의 오수관 연결방법Sewage pipe connection method of the present invention

이와 같이 조립된 본 발명의 전기융착이음관(10)은 다음과 같이 오수관 또는 우수관을 구성하는 두 파이프(18)(18')의 연결단부를 연결하는데 사용된다.The electrofusion joint pipe 10 of the present invention assembled as described above is used to connect the connecting ends of the two pipes 18, 18 'constituting the sewage pipe or rain pipe as follows.

먼저, 제1단계에서, 고정밴드(16), 지지시이트(14)와 발포시이트(12)로 구성되는 전기융착이음관(10)은, 도 5 내지 도 7에서 보인 바와 같이, 그 반부분이 일측 파이프(18)의 일측단부에 연결고정된다. 이러한 연결과정은 파이프(18)(18')의 매설지 현장이 아닌 파이프의 제공자 작업장에서 수행된다.First, in the first step, the electrofusion joint pipe 10 composed of the fixing band 16, the support sheet 14 and the foam sheet 12, as shown in Figs. It is connected and fixed to one end of one side pipe 18. This connection process is performed at the provider's workshop of the pipe, not at the site of the burial of the pipes 18, 18 '.

즉, 파이프제공자의 작업장에서 생산되어 준비된 파이프(18)의 일측단부의 외면에 전기융착이음관(10)이 약간 전개된 상태에서 그 반부분만 덮어씌우듯이 삽입된다(도 6 참조). 그리고 전기융착이음관(10)의 나머지 반부분에는 파이프(10)의 직경과 동일하나 길이가 전기융착이음관(10)의 반폭길이에 해당하는 지지관(50)을 삽입한다. 그리고 고정밴드(16)를 볼트(46)로 조여 그 직경을 감소시킴으로서 전기융착이음관(10)의 내면측에 위치하는 발포시이트(12)가 파이프(18)와 지지관(50)의 외면상에 밀착되게 한다.That is, the electric fusion joint pipe 10 is inserted into the outer surface of one end of the pipe 18 produced and prepared in the pipe provider's workshop as if only half of it is covered (see FIG. 6). And the other half of the fusion joint pipe 10 is inserted into the support tube 50 is the same as the diameter of the pipe 10, but the length is half the width of the fusion joint pipe (10). By tightening the fixing band 16 with the bolt 46 to reduce the diameter, the foam sheet 12 located on the inner surface side of the electrofusion joint pipe 10 is formed on the outer surface of the pipe 18 and the support pipe 50. Keep in close contact with

그리고 파이프(18)의 일측단부의 외면에 전기융착이음관(10)의 반부분이 배치됨으로서 발포시이트(12)는 이러한 반부분의 위치에 놓이는 전열선패널(28)이 파이프(18)의 단부외면상에 배치될 것이다. 그리고 발포시이트(12)의 중간부분(27)의 중앙은 파이프(18)와 지지관(50)의 경계선상에 놓일 것이다.And since the half of the electrofusion joint pipe 10 is disposed on the outer surface of one end of the pipe 18, the foam sheet 12 is a heating wire panel 28, which is placed at the position of the half portion is the outer surface of the end of the pipe 18 Will be placed on. And the center of the middle portion 27 of the foam sheet 12 will be placed on the boundary between the pipe 18 and the support tube 50.

이와 같은 상태에서, 발포시이트(12)의 전열선패널(28)에 온도센서(34)를 이용하여 발포시이트(12)내의 발열온도를 감지하는 동시에 도선(32)(32')을 통하여 전원을 인가하여 발포시이트(12)내의 전열선패널(28)이 발열되게 한다.In this state, the heating wire panel 28 of the foam sheet 12 senses the heat generation temperature in the foam sheet 12 using the temperature sensor 34 and at the same time supplies power through the conductors 32 and 32 '. Thus, the heating wire panel 28 in the foam sheet 12 is heated.

발포시이트(12)의 전열선패널(28)이 발열되면 발포시이트(12) 자체가 용융되기 시작하고 이에 혼합되어 있는 발포제의 작용으로 용융물이 발포되면서 체적이 증가한다. 이러한 전열선패널(28)에 의한 발포시이트의 용융, 발포와 동시에 전열선패널(28)의 발열에 의하여 파이프(18)의 연결단부의 외면 일부도 극히 제한적이지만 부분적인 용융이 일어나 용융발포되는 발포시이트(12)와의 열융착이 이루어진다. 또한 동일한 조건으로 전열선패널(28)에 해당하는 발포시이트(12)의 부분과 지지시이트(14) 사이에도 열융착이 이루어진다.When the heating panel 28 of the foam sheet 12 is heated, the foam sheet 12 itself starts to melt and the volume increases as the melt is foamed by the action of the blowing agent mixed therein. At the same time as the melting and foaming of the foam sheet by the heating panel 28, a part of the outer surface of the connection end of the pipe 18 is also extremely limited due to the heat generation of the heating panel 28, but partial melting occurs and the foam sheet is melt-foamed. 12) Thermal fusion is achieved. In addition, heat fusion is also performed between the portion of the foam sheet 12 corresponding to the heating panel 28 and the support sheet 14 under the same conditions.

이와 같이, 전기융착이음관(10)의 발포시이트(12)가 그 반부분에서 전열선패널(28)의 발열로 열융착이 이루어지고 나머지 반부분의 내부에는 지지관(50)이 지지된 상태에서 파이프(18)는 그 일측단부에 부분적으로 전기융착이음관(10)이 결합된 상태로 제공자에 의하여 오수관 매설지로 공급될 수 있다.As such, the foam sheet 12 of the electrofusion joint pipe 10 is heat-sealed by heat generation of the heating panel 28 at its half portion, and the support tube 50 is supported inside the remaining half portion. The pipe 18 may be supplied to the sewage pipe embedding site by the provider with the electrofusion joint pipe 10 partially coupled to one end thereof.

일측단부에 부분적으로 전기융착이음관(10)이 결합된 상태로 오수관 매설지로 공급된 파이프(18)들은 이미 이러한 일측 파이프(18)에 전기융착이음관(10)이 융착연결되어 있는 상태에서 이러한 파이프(18)에 연결되는 타측 파이프(18')(이러한 타측 파이프역시 일측단부에 전기융착이음관이 부분적으로 융착결합되 있는 것이다)의 타측단부를 접속하여 전기융착이음관의 나머지 반부분을 융착결합할 수 있다. 즉, 오수관 매설지에 공급된 파이프(18)에서 체결되어 조여져 있는 전기융착이음관(10)의 고정밴드(16)를 느슨히 풀고 지지관(50)을 분리해낸다. 그리고 융착작용이 일어나지 않은 발포시이트(12)의 전열선패널(26)에 해당하는 반부분의 위치에 타측 파이프(18')의 타측단부를 삽입하고 고정밴드(16)를 조여 전기융착이음관(10)의 나머지 반부분이 타측 파이프(18')에 밀착되게 한다. 타측 파이프(18')의 타측단부상에 위치하는 발포시이트(12)의 전열선패널(26)에 온도센서(34)를 이용하여 발포시이트(12)의 이러한 전열선패널(26)내의 발열온도를 감지하는 동시에 도선(32)(32')을 통하여 전원을 인가하여 발포시이트(12)내의 전열선패널(26)이 발열되게 한다.The pipes 18 supplied to the sewage pipes in a state in which the electrofusion joint pipe 10 is partially coupled to one end thereof are already connected to the one pipe 18 in the state in which the electrofusion joint pipe 10 is fusion-connected. The other half of the electric fusion joint pipe is welded by connecting the other end of the other pipe 18 'which is connected to the pipe 18 (the other pipe is also partially fusion-bonded to one end). Can be combined. That is, the fixing band 16 of the electrofusion joint pipe 10 fastened and tightened by the pipe 18 supplied to the sewage pipe buried place is loosened and the support pipe 50 is separated. Then, the other end of the other pipe 18 'is inserted into a half portion corresponding to the heating wire panel 26 of the foam sheet 12 in which no fusion occurs, and the fixing band 16 is tightened to make the electrofusion joint pipe 10 The other half of the) is pressed against the other pipe 18 '. The heating sensor panel 26 of the foam sheet 12 located on the other end of the other pipe 18 'is used to sense the heat generation temperature in the heating sheet panel 26 of the foam sheet 12 using the temperature sensor 34. At the same time, power is applied through the conductive wires 32 and 32 'so that the heating wire panel 26 in the foam sheet 12 is heated.

발포시이트(12)의 전열선패널(26)이 발열되면 전열선패널(26)에 의한 발포시이트의 용융, 발포와 동시에 전열선패널(26)의 발열에 의하여 파이프(18')의 외면과 함께 부분적인 용융이 일어나 용융발포되는 발포시이트(12)와의 열융착이 이루어진다. 또한 동일한 조건으로 전열선패널(26)에 해당하는 발포시이트(12)의 부분과 지지시이트(14) 사이에도 열융착이 이루어진다.When the heating panel 26 of the foam sheet 12 is heated, the foam sheet is melted and foamed by the heating panel 26 and partially melted together with the outer surface of the pipe 18 'by the heating of the heating panel 26 at the same time. This occurs and thermal fusion is performed with the foam sheet 12 which is melt-foamed. In addition, heat fusion is also performed between the portion of the foam sheet 12 corresponding to the heating panel 26 and the support sheet 14 under the same conditions.

그리고, 발포시이트(12)의 타측부분(12b)에서 중간부분(27)의 경계를 이루는 일측 광폭패널부분(26')의 변부가 길이방향 축선(L)을 지나 타측 광폭패널부분(28')의 대응하는 변부에 좁은 간격 d2을 두고 근접하여 배치되이 있으므로 발포시이트(12)의 일측단부(12a)에 중첩되는 타측단부(12b)가 그 중첩부분의 중간부분(27)의 영역을 포함하여 전체에서 발포시이트(12)의 일측단부(12a)에 확고하게 융착되어 융착작용이 일어나지 않은 중간부분(27)을 따라 누수가 일어나는 것을 방지할 수 있다.Then, the edge portion of one wide panel portion 26 ′ forming the boundary of the middle portion 27 from the other portion 12 b of the foam sheet 12 passes through the longitudinal axis L and the other wide panel portion 28 ′. The other end 12b overlapping the one end 12a of the foam sheet 12 includes the region of the middle portion 27 of the overlapping portion, because it is disposed close to the corresponding side of the sheet at a narrow distance d2. In the foam sheet 12 is firmly fused to one side end portion 12a can be prevented from leaking along the intermediate portion 27, the fusion action did not occur.
