Description

The entry unit {ENTRY UNIT}

The present invention relates to an entry unit, and more particularly, to an entry unit which, when a pipe passes through a wall (for example, a wall of a manhole or a wall of a building) partitioning a space and a space, Entry unit.

When a pipe for sewerage, a pipe for heating or the like passes through a wall of a manhole or various pipes pass through a wall of a building, a sleeve method is mainly used for guiding the pipe and fixing the pipe to the wall.

Referring to FIG. 1, in the case of a manhole,

In order to prevent foreign matter from flowing into the manhole through the space between the sleeve pipe A and the pipe 2 when the pipe 2 passes through the wall 1 of the manhole, ).

However, as time passes, the pipe 2 is stretched along the longitudinal direction of the pipe 2 due to the surrounding environment and the temperature of the fluid, or vibration occurs in the ground, . &Lt; / RTI >

In this case, due to the limitation of the release material and the limitation of the heat shrinkable casing (B), there is a problem that the foreign matter can not be completely prevented from flowing into the manhole.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems,

And it is an object of the present invention to provide an entry unit in which a foreign object can be completely prevented from entering the elongated pipe.

In order to solve the above problems, an entry unit according to the present invention includes:

The outer periphery of the guide pipe and the wall are sealedly engaged,

A wave tube is formed at one end of the guide pipe located outside of the wall,

A guide tube is formed at the other end of the guide pipe located on the inner side with respect to the wall,

And an end of the corrugated tube is fixedly coupled to the outer circumference of the pipe for sealing.

The entry unit according to the present invention,

It is possible to completely prevent the inflow of the foreign matter into the elongation of the pipe.

1 is a front sectional view of the prior art;
2 is a perspective view of an entry unit according to the present invention;
3 is an exploded perspective view of an entry unit according to the present invention;
4 is a front sectional view of an entry unit according to the present invention.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Prior to the explanation, the direction of the corrugated pipe 12 is referred to as a front side and the direction of the straight pipe 13 is referred to as a rear side on the basis of Fig. 2,

The description will be made on the basis of an example in which an entry unit is applied to the wall 1 of a manhole among walls (for example, a wall of a manhole or a wall of a building) partitioning a space and a space to which the entry unit of the present invention can be applied do.

[0030] Referring to the configuration of the entry unit according to the present invention,

The guide pipe (10)

As shown in Figs. 2 to 4,

The inserting hole 11 through which the pipe 2 for pipes such as a double insulated pipe passes is formed in the inside of the wall 1 along the longitudinal direction of the guide pipe 10.

At this time, the outer periphery of the intermediate portion of the guide pipe 10 and the wall body 1 of the manhole are joined to be sealed by welding or the like.

Therefore, no water or foreign matter flows between the guide pipe 10 and the wall 1 of the manhole.

The wave tube (12) ,

As shown in Figs. 2 to 4,

Is formed at one end of a guide pipe (10) located outside (1a: outside the manhole) with reference to the wall (1) of the manhole. The end of the corrugated pipe (12) And is sealed and fixedly coupled.

The corrugated pipe 12 is integrally formed with the flange portion 121 fixed to the outer circumferential surface of the pipe 2 by welding or the like and the flange portion 121 and the guide pipe 10 And a formed wrinkle portion 122.

Therefore, the end of the corrugated tube 12 is sealed by the flange portion 121 with the outer circumferential edge of the pipe 2.

At least one of the corrugations 122 of the corrugated tube 12 is formed, and the number of corrugations 122 may be increased as necessary.

Generally, when a pipe 2 for a pipe is provided in a wall 1 of a manhole, the pipe 2 is elongated in the longitudinal direction due to a change in ambient temperature over time.

When the shape of the one end of the guide pipe 10 (the end portion exposed to the outside of the manhole) provided to penetrate the wall 1 of the manhole is not a corrugated waveform, the guide pipe 10 and the pipe 2 Is damaged, and water or foreign matter enters the inside of the manhole through the damaged joint portion.

However, according to the configuration of the present invention as described above,

When the pipe 2 extends due to the surrounding environment and the temperature of the fluid over time, the corrugation of the corrugated pipe 12 fixedly connected to the pipe 2 by the flange portion 121 122 are simultaneously stretched along the movement of the pipe 2.

Therefore, due to the shape of the corrugated pipe 12, the joint portion between the guide pipe 10 and the pipe 2 is prevented from being damaged and completely sealed, so that water or foreign matter can be prevented from flowing into the inside of the manhole have.

Even if vibration occurs in the ground due to the surrounding environment and the pipe 2 for the pipe flows in the vertical direction, the guide pipe 10 and the pipe 2 for pipes Is prevented from being damaged and is completely sealed, it is possible to prevent water or foreign matter from entering the inside of the manhole.

Accordingly, there is an additional effect of reducing the maintenance and management costs of the entry unit according to the present invention and providing a convenient working environment to the operator.

The date tube (13) ,

As shown in Figs. 2 to 4,

Is formed at the other end of the guide pipe (10) located inside (1b: inside the manhole) with respect to the wall (1) of the manhole. The end of the straight pipe (13) Respectively.

The guiding flange 131 and the guiding flange 131 are slidably formed along the outer circumferential surface of the pipe 2 at the end of the guiding tube 13, Are welded together.

According to the above configuration, when the pipe 2 extends due to the ambient environment and the temperature of the fluid, the pipe 2 is naturally stretched by the guide flange 131 of the straight pipe 13 do.

The heat insulating material (20)

As shown in Figure 4,

A variety of insulating materials can be used as needed, such as unglazed foam insulation, grapeseed, etc., between the guide pipe (10) and the pipe (2).

While the present invention has been described with reference to the accompanying drawings, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the invention. Should be interpreted as falling within the scope of protection.
