Description

The connecting structure of the corrugated pipe

[0001] The present invention relates to a joint pipe for connecting a corrugated pipe, and more particularly, to a joint pipe for connecting corrugated pipes continuously, wherein an irregular circumferential space is formed along a screw thread formed on an inner wall surface of the joint pipe, Silicon is filled in the space to prevent stenosis from flowing into the joint tube

In addition, a barrier wall is formed on both sides of the space so as to intercept the silicon introduced into the space, and the barrier wall is formed around the arc of the thread and the screw thread formed on the inner wall surface of the joint pipe, And to provide a technique for separating the gap between the inner side wall of the joint pipe and the outer side wall of the corrugated pipe.

Conventionally, when constructing an electrical manhole, various structures have been proposed in which a pipe for receiving a cable is embedded in a concrete wall in a mold frame of an acceptor hole.

The pipe that receives the cable uses a straight pipe or a corrugated pipe. In the case of using a straight pipe, various waterproof pipes are proposed and used.

7, a watertight pipe or a straight pipe 41 is provided in the manhole 50, and a water pipe or an adapter having a wave tube at the opposite side of the straight pipe to the outside of the straight pipe (41) (40), and connects the corrugated tube (42) to the outside of the adapter (40).

After the sealing tape 43 is wound around the connecting portion of the adapter 40 and the straight pipe 41 and the PVC tape 45 is wrapped around the outer surface of the PVC tape 45, ) And the corrugated pipe (42), the sealing tape (43) and the elastic tape (44) were wrapped and finished.

However, since the conventional wave tube connection structure is constructed by assembling and connecting a plurality of tubes and fixing the connection portions by tape in multiple layers, the assembling process is very complicated and the operation is very difficult due to working in the underground, There is a problem that the connection part is easily separated and various foreign substances or water are introduced into the connection part.

In order to solve such a problem, it should be noted that the assembled joint pipe 10 according to the Korean Intellectual Property Office Publication No. 10-2015-0071358 invented and filed by the applicant, (12) filled with silicone (including an adhesive material) is formed along the screw thread of the screw thread formed in the joint pipe (10) so that silicon is filled between the side wall and the outer wall of the corrugated pipe (100) The space 12 is connected to an inlet 13 penetrating the space 12 so as to fill the space 12 with silicon.

In such a structure, when silicon is injected into the space portion 12 through the injection port 13, the silicon is injected in a threaded direction along the threaded cores of the corrugated pipe 100, and when silicon is injected into the threaded cores, In addition, there is a drawback that water flows in from the outside through the thread direction, and there is a disadvantage in that water is introduced from the outside into the inside of the joint pipe, and the portion where the joint pipe is not separated from the joint pipe (in the joint pipe, Silicon is not introduced), and silicon is not introduced into the portion not separated, so that water is infiltrated.

In consideration of the above-mentioned problems (corresponding to No. 10-2015-0071358)

The present invention provides a prefabricated joint pipe capable of continuously connecting a plurality of corrugated pipes, wherein an irregular circumferential void portion is formed along a threaded bone and a screw thread formed on an inner wall surface of the prefabricated joint pipe, Ensure that water does not enter the inside of the diaphragm tube

The blocking wall is formed around the circular arc along a threaded line and a thread formed on the inner wall surface of the coupling pipe so that the silicon is blocked by the blocking wall. And separating the gap between the inner wall of the joint pipe and the outer wall of the corrugated pipe.

When the above object is achieved, silicon is injected into the space portion (corresponding to the valley) corresponding to the silicon main entrance chamber, so that water or stagnant matter does not flow into the inside of the corrugated tube.

A more detailed purpose is revealed in detail.

As shown in the figure, a joint type joint pipe 10 for connecting a plurality of corrugated pipe tubes 100 formed in a screw shape is threaded so as to be engaged with a thread of the corrugated pipe 100, (Not shown), and is divided into two parts in the longitudinal direction so as to cover the outer wall of the corrugated pipe 100. In the prefabricated joint pipe,

The prefabricated joint pipe 10 has a space 12 in which silicon is filled in the inner wall of the joint pipe 10 so that silicon is filled between the inner wall of the joint pipe 10 and the outer wall of the corrugated pipe 100 And the space 12 is formed around the arc of the coupling pipe 10 along the thread A and the thread B formed on the inner wall surface of the coupling pipe 10, 13)

The thickness of the silicon 300 flowing into the inner side wall of the joint pipe through the silicon injection port 13 in both directions of the space 12 may be thinly formed as a unit with the joint pipe in the molding process. The blocking wall 12 'is formed around the arc of the screw thread A and the thread B formed on the inner wall surface of the coupling pipe 10.

The joint pipe 12 connects one end C of the tube 20 which contracts when heat is applied to both ends of the tube 20. The other end D of the tube 20 accommodates one end of the tube 100 and heats the heat And is formed to be in close contact with the outer wall of the corrugated pipe (100).

And an adhesive layer 310 is formed on the inner wall of the tube 21.

The silicon injection port 13 is formed to penetrate through the space 12 and a plurality of silicon injection ports 13 are formed in the space 12 so that silicon can be injected into the space 12 at any position.

As described above, the present invention provides a prefabricated joint pipe for continuously connecting corrugated pipes, wherein an irregular circumferential space portion is formed along threaded threads formed on the inner wall surface of the prefabricated joint pipe, and the space is filled with silicon Preventing the stenosis from flowing into the joint tube,

In addition, a barrier wall is formed so as to intercept the silicon introduced into the space portion in both directions of the space, and the barrier wall is formed around the arc of the screw thread and the screw thread formed on the inner wall surface of the joint pipe

 By blocking the silicon by the barrier wall, the effect of filling the silicon in the defined space (between the barrier wall and the barrier wall) without further charging

 In addition, since it plays a role of separating the gap between the inner side wall of the joint pipe and the outer side wall of the corrugated pipe

Silicon is introduced between the corrugated tube and the joint tube, which has the effect of blocking stenosis (including moisture).

The above-mentioned effects are more specifically described.

Fig. 2 is an exploded perspective view of Fig. 1,
Figure 3 is a perspective view from a different angle in the state of Figure 2,
Fig. 4 is a perspective view of a main part of the present invention,
Fig. 5 is a perspective view showing a tube formed at both ends in the state of Fig. 1,
6 is a perspective view of an embodiment in which a conventional corrugated pipe is connected to a prefabricated joint pipe for connecting a corrugated pipe according to the present invention.

It is somewhat inconvenient to understand if the drawings attached herewith are attached with black and white drawings.

Therefore, I attached it as a color drawing for easier understanding.

For reference, the attached drawings are drawings constructed by organically utilizing a plurality of ked programs. Please note.

1 to 6, and a description will be made of another embodiment of the present invention.

Silicon in the city is embedded in a separate color body so as to be easily distinguished. In particular, the blocking wall 12 is formed in the same color when the joint pipe 10 is molded.

The reason why the barrier walls have different colors in the city is that they are distinguished from each other.

The assembly type joint pipe 10 connecting the plurality of corrugated pipe tubes 100 formed in a screw shape is threaded to be engaged with the thread of the corrugated pipe 100 and is fixed while being pressed against the outer wall of the corrugated pipe And a fastening means (not shown), and is longitudinally cut so as to cover the outer wall of the corrugated pipe 100,

The prefabricated joint pipe 10 has a space 12 in which silicon is filled in the inner wall of the joint pipe 10 so that silicon is filled between the inner wall of the joint pipe 10 and the outer wall of the corrugated pipe 100 And the space 12 is formed around the arc of the coupling pipe 10 along the thread A and the thread B formed on the inner wall surface of the coupling pipe 10, 13)

The thickness of the silicon 300 flowing into the inner side wall of the joint pipe through the silicon injection port 13 in both directions of the space 12 may be thinly formed as a unit with the joint pipe in the molding process. The blocking wall 12 'is formed around the arc of the screw thread A and the thread B formed on the inner wall surface of the coupling pipe 10.

An embodiment of such a configuration will be described below.

The corrugated pipe 100 is screwed (loosely coupled) to the threads of the corrugated pipe 100 with the inside thread of the joint pipe at both ends with the joint pipe 10 therebetween.

In this way, the blocking wall 12 'formed inside the coupling pipe 10 in the process of screwing is not so much an obstacle to the threaded connection because the blocking wall is thin and collapses in the process of screwing the corrugated pipe.
That is, the blocking wall 12 'is crushed during the corrugating process

So that silicon is implanted between the blocking wall 12 'and the blocking wall 12'

Next, a process of injecting silicon between the blocking wall 12 'and the blocking wall 12' will be described.

When the corrugated pipe 100 is screwed into the coupling pipe 10, as shown in the drawing, the threaded connection is loosely coupled, so that a space is formed between the outer wall of the corrugated pipe 100 and the inner wall of the coupling pipe 10.

In this state, when silicon is injected at a certain pressure or higher through the silicon injection port 13, the silicon is charged into the blocking wall 12 'at both ends of the space portion 12 via the silicon injection port 13 and the space portion 12 do.

The blocking wall 12 'is thus formed and the silicon is no longer charged.

If the blocking wall 12 'is not present, the silicon is constantly charged along the threads, and the filling does not evenly distribute the silicon.

As described above, when the silicon is filled, silicon is filled in the first space portion 12, thereby blocking the inflow of the primary stenosis and blocking the secondary stenosis due to the blocking wall.

The tube 20 will now be described.

One end C of the tube 20 contracts when the heat is heated at both ends of the joint pipe 12 and the other end D of the tube 20 accommodates one end of the tube 100 to heat the tube, 100 of the present invention.

Hereinafter, an embodiment will be described.

5, when the tube 20 is heated at both ends of the tube 20 after receiving the tube 100 at both ends of the tube 20, the tube 20 is contracted as shown in the state of FIG. 6 and is wound around the outer wall of the tube 100 And is tightly fixed.

The steric material does not flow between the inner side wall of the tube 20 and the outer side wall surface of the corrugated tube 100.

The adhesive layer 310 is formed on the inner wall of the tube 20 so that the inner wall of the tube 20 and the outer side of the corrugated tube 100 are more firmly coupled.

Hereinafter, a plurality of silicon injection holes will be described.

The silicon injection port 13 is formed to penetrate from the space portion 12 to the outside and a plurality of silicon injection holes 13 are formed in the space portion 12 so that silicon can be injected into the space portion 12 at any position .

Since a plurality of the silicon injection holes 13 are formed along the space, silicon can be injected in a plurality of directions, which is convenient. Further, the silicon is injected evenly by injecting in the plural direction.

The corrugated pipe of the present invention is used to install a corrugated pipe (100) in a narrow manhole.

Therefore, silicon must be able to be implanted in any direction.

If the silicon injection port 13 is formed in one place, silicon injection is not possible in the narrow manhole if the silicon injection port 13 is directed to the lower end due to the working conditions.

Please note this.

The joint pipe (10) is divided into two parts in the longitudinal direction, and the two joint pipes, which are divided into two parts, are respectively formed with flanges, and the flanges of the two joint pipes are arranged to face each other.

As described above, the present invention is a very advantageous invention because a silicon injection hole for injecting silicon and a space for filling silicon are formed, and a plurality of silicon injection holes and a barrier wall for blocking silicon are formed.

Such a configuration is a technical configuration that can not be easily conceived by a person having ordinary knowledge.
