Description

Assembly type joint pipe

The present invention relates to an assembly type joint pipe, and more specifically, it is possible to easily install and improve a joint pipe for connecting water pipes, sewer pipes, sewage pipes, oil pipes, and gas pipes buried in the ground according to the intended use. The present invention relates to an assembled joint pipe which can be bent freely in up, down, left and right directions to connect a pipe.

Generally, cast water pipes, steel pipes, and PE pipes are used for water supply pipes, and cement concrete fume pipes, PE spiral pipes, and PE double wall pipes are used for sewage pipes. Steel pipes, PE double wall pipes, PE spiral pipes, etc. are used, and oil pipes, steel pipes, cast iron pipes, etc., and gas pipes, PE pipes, steel pipes, etc. are used.

In particular, in recent years, an expensive pipe coated with a synthetic resin on the inner surface of the pipe is used. The reason is that cement concrete fume pipes, cast iron pipes, or steel pipes have sufficient rigidity to withstand the internal pressure, but they are not easily corroded to acid, alkali, factory wastewater, sewage, seawater, etc. It has the disadvantage of being scaled (usually called scale) to reduce the internal cross-section of the tube. Of course, removing these scales is not easy and expensive. In comparison, pipes made of polyethylene (PE) -based synthetic resins are not affected by chemicals such as acids and alkalis, and do not corrode to highly corrosive materials such as factory wastewater, sewage, and seawater, depending on their durability. do. Therefore, a tube coated with a synthetic resin on the inner surface of the tube is used.

However, despite the use of expensive pipes coated with synthetic resin on the inner surface of the pipes, there are no joint tubes of various angles that can be applied to the site conditions when installing these pipes. It is used to cut and connect by welding, etc. Therefore, the inner surface of the connecting portion is not coated with synthetic resin, causing corrosion or scale, and water leakage is reduced, so that water leakage occurs and contaminates soil and groundwater. Of course, the pipe having a small diameter of 300 mm or less is provided with a pipe formed integrally with a joint pipe in a part of the pipe, but it is difficult to transport or install the integrated pipe, and there is no ability to cope with the situation in the workplace. There is a disadvantage that the workability is reduced. In addition, there is no joint pipe in a tube having a large diameter of 450 mm or more in diameter.

In addition, to address the problem of the development of the assembled joint pipes, manholes are often installed because there is no such joint pipe in the position where only one elbow having 45 ° or 90 ° is required. In addition, the manhole cover that is exposed to the ground is broken, there is a problem that causes traffic accidents and people fall accident.

In addition, in the case of sewage pipes there is a very difficult disadvantage to remove the work accumulated in the interior of the pipe. In other words, if the work area is 50m or more, there is a hassle and cost loss of breaking a piece of pipe around the middle point for removing the soil, and installing a new pipe after the work.

In addition, in the process of using sewage pipes, sewage pipes, water pipes, oil pipes, and gas pipes, if other facilities are buried under the ground, there are many types of elbows that can avoid them. This will happen. There are numerous places where power cables or wastewater pipes pass through the sewer pipes, and in this case, the pipes are bent by cutting a part of the pipe as described above, and then the connection part is manufactured and installed by handwork in the form of a melt joint. As a result, the water tightness is deteriorated, which causes a problem of polluting the soil or the water supply by leakage.

In addition, when a problem occurs in a straight pipe or a joint part to dig soil and dismantle the pipe, conventionally, because one pipe cannot be separated, only one pipe cannot be dismantled, and thus a whole section must be lifted. There is a hassle and a cost loss.

The present invention has been made in order to solve the various problems as described above, the purpose is to have a component consisting of a socket (Socket), reducer (Elducer), elbow (Tee), each Regardless of the installation angle, material, and size of the tube, the components can be easily and reliably installed by applying them to the site situation, and only the corresponding parts can be easily dismantled for maintenance workability. It is to provide an improved assembled pipe.

In addition, another object of the present invention is to provide a pipe connection method using the assembled joint pipe.

Assembled joint pipe according to the present invention for achieving the above object is a prefabricated joint pipe for connecting a synthetic resin pipe for large diameter (450 mm or more in diameter), and has a pipe joint formed through the coupling hole of a predetermined diameter therein A flange portion having a plurality of fastening holes is integrally formed at one end of the pipe coupling portion, and a part of the coupling hole has a locking projection integrally formed therein; A pipe coupling part having a coupling hole having a smaller diameter than the coupling hole of the socket is formed, and one end of the pipe coupling part is integrally formed with an inclined portion that is formed to extend outwardly, and an end of the inclined portion corresponding to the flange portion of the socket is formed. A flanger having a fastening hole integrally formed, and a part of the coupling hole having a locking projection integrally protruding; An elbow having a bent portion bent at a predetermined angle, and a flange portion integrally formed at both ends of the bent portion, each having a fastening hole corresponding to the flange portion of the socket; And a tee integrally formed on one side of the horizontal portion so as to communicate with each other, and a flange portion integrally formed at both ends of the horizontal portion and one end of the vertical portion, each having a fastening hole corresponding to the flange portion of the socket.
