Description

Watertight ring of buried hume pipe {Ring for watertight of hume concrete pipe}

The present invention relates to a watertight ring for a buried Hume pipe, and more particularly, to a watertight ring for a buried Hume pipe that performs a watertight function by being interposed between binding parts of adjacent Hume pipes.

In general, a hume pipe buried in the ground for smooth drainage of sewage or wastewater is made into a cylindrical shape of a predetermined standard and bound together to form a pipeline, and can be drained to a separately installed normal sewage treatment facility there will be

Since the sewage or wastewater flowing along the pipeline of the Hume pipe contains a large amount of sediment, when these sediments accumulate on the inner surface of the pipe, the effective pipe diameter of the Hume pipe is reduced, making it difficult to drain smoothly, as well as the decay of the sediment. It can cause odor, and when a large amount of rainfall occurs during the rainy season, there is a problem in that backflow occurs due to insufficient water passing capacity.

Therefore, in the case of installing a Hume pipe to solve the above problems, most of them have a certain slope so that the flow rate of sewage or wastewater flowing inside the Hume pipe is maintained at a minimum flow rate or more.

And, the other Hume pipe bound to the first Hume pipe 10 will be described as the second Hume pipe 20.

A seating surface 12 having a smaller diameter than the outer diameter of the first Hume pipe 10 may be formed at one end of the first Hume pipe 10 by a predetermined length.

Here, a watertight ring 100, which will be described in detail later, is inserted and fixed to the seating surface 12 of the first Hume pipe 10.

For reference, of course, the socket portion 22 is formed at the other end opposite to one end of the first Hume pipe 10 where the seating surface 12 is formed.

On the other hand, in order for one end of the first Hume pipe 10 to be inserted into the other end of the second Hume pipe 20, the diameter of its inner circumferential surface 22a is equal to or slightly larger than the outer diameter of the first Hume pipe 10 Socket portion (22) can be formed.

As shown in FIGS. 3 to 5, the watertight ring 100 interposed between the binding parts of the Hume pipes 10 and 20, which can be configured as described above, is inserted into one end of the first Hume pipe 10, As fitted, a seating portion 130 that is seated and supported in close contact with the seating surface 12 in a state of being inserted into one end of the first Hume pipe 10, and a substantially perpendicular direction from one side end of the seating portion 130 A support part 120 that is formed to extend by a certain length and is in close contact with and supported by the stepped surface dividing the seating surface 12 of the first Hume pipe 10 and the outer circumferential surface, and a substantially right angle from one end of the support part 120 The cover part 110 extending by a certain length in the direction and forming a direction parallel to the seating part 130, and the contact part 140 extending from the other end of the seating part 130 by a certain length in a substantially perpendicular direction. ), and these seating part 130, support part 120, cover part 110 and close contact part 140 may be provided with rubber or silicone material and manufactured integrally.

In addition, the watertight ring 100 according to an embodiment of the present invention is configured to further include a water expansion index agent 200 interposed in the space formed between the seating portion 130 and the cover portion 110. can

In addition, the watertight ring 100 according to an embodiment of the present invention is formed by extending by a certain length from one surface of the seating portion 130 toward the cover portion 110, so that the seating portion 130 and the cover portion 110 ) It may be made of a configuration further including a protection unit 150 to prevent the separation of the water expansion index agent 200 interposed in the space between, and at this time, the protection unit 150 is also integrated with the seating unit 130 It can be made into a mold.

Here, the protection part 150 is formed by extending a certain length from one surface of the seating part 130 in the direction of the cover part 110, and its end is rounded toward the support part 120, so that water expands. It is desirable to more stably protect the waterstop agent 200.

At this time, when the water expansion index agent 200 expands later, the protector 150 preferably has a shape in which its cross-sectional area gradually narrows toward the end so that elastic deformation is facilitated.

On the other hand, even in the case of the cover part 110, it is preferable to more stably protect the water expansion coefficient agent 200 by forming the protrusion 112 so as to protrude in the direction of the seating part 130 at its end.

A process of bonding the first Hume pipe 10 and the second Hume pipe 20 adjacent to each other using the watertight ring 100 having the above configuration will be described as follows.

First, as shown in FIG. 4, the watertight ring 100 according to the embodiment of the present invention is inserted and fixed to the seating surface 12 formed at one end of the first Hume pipe 10.

At this time, the seating portion 130 of the watertight ring 100 is in close contact with the seating surface 12 of the first Hume pipe 10, and the support portion 120 of the watertight ring 100 is of the first Hume pipe 10. It is in close contact with the stepped surface, and the close contact portion 140 is in close contact with the end surface 14 forming the seating surface 12 and perpendicular to it.

In this state, the end of the first Hume pipe 10 to which the watertight ring 100 is mounted is inserted into the socket portion 22 of the second Hume pipe 20. At this time, the cover portion 110 of the watertight ring 100 ) is inserted while being bent back by the socket portion 22 of the first Hume tube 10.

Therefore, the cover part 110 of the watertight ring 100 is positioned between the outer circumferential surface of the first Hume pipe 10 and the inner circumferential surface 22a of the socket portion 22 of the second Hume pipe 20, and the first Hume pipe ( Between the seating surface 12 of 10) and the inner circumferential surface 22a of the socket portion 22 of the second Hume pipe 20, the seating portion 130 of the watertight ring 100, the water expansion index agent 200, and the protection unit (150) is located.

In addition, the contact portion 140 is positioned between the end face 14 of the first Hume pipe 10 and the end face 22b perpendicular to the inside of the socket portion 22 of the second Hume pipe 20.

Therefore, the end of the first Hume pipe 10 and the socket portion 22 of the second Hume pipe 20 are bonded to each other as shown in FIG. 5, so that a triple watertight seal is achieved.

That is, the primary watertightness is achieved by the contact portion 140 located between the end face 14 of the first Hume pipe 10 and the end face 22b of the socket portion 22 of the second Hume pipe 20, , Secondary watertightness is achieved by the water expansion index agent 200 located between the seating surface 12 of the first Hume pipe 10 and the inner circumferential surface 22a of the socket portion 22 of the second Hume pipe 20, , The third watertightness is achieved by the cover part 110 located between the outer circumferential surface of the first Hume pipe 10 and the inner circumferential surface 22a of the socket part 22 of the second Hume pipe 20.

In this way, the first Hume pipe 10 and the second Hume pipe 20, which are bound to each other, are bound in a triple watertight structure, and the watertightness is maximized to prevent leaks such as sewage or wastewater flowing through the pipe more reliably It can be.

At this time, the water expansion index agent 200 interposed between the seating surface 12 of the first Hume pipe 10 and the inner circumferential surface 22a of the socket portion 22 of the second Hume pipe 20 expands as it comes into contact with water. By doing this, the watertight effect can be further increased.

For example, as shown in FIG. 2, when the binding portion of the buried Hume pipe is dislocated, the end face 14 of the first Hume pipe 10 and the inner end face of the socket portion 22 of the second Hume pipe 20 ( As the close contact part 140 interposed in 22b) does not properly exhibit a watertight function, sewage, etc. is discharged from the seating surface 12 of the first Hume pipe 10 and the inner circumferential surface of the socket portion 22 of the second Hume pipe 20. Outflow can be made between (22a), and in this case, the water-tightness can be maintained as it is by being expanded by sewage or the like into which the water expansion index agent 200 is introduced.

That is, as the water expansion index agent 200 expands by contact with water, the contact area with the inner circumferential surface 22a of the socket portion 22 of the second Hume pipe 20 increases, and also of the watertight ring 100 As the seating portion 130 is pressurized, the watertightness can be further maximized by eliminating gaps.

Therefore, even if the binding parts of the first Hume pipe 10 and the second Hume pipe 20 adjacent to each other are displaced due to the load of the ground, etc., the watertightness is maintained, so that sewage and wastewater flowing through the pipe flow out to the ground The effect of suppressing the occurrence of environmental pollution, such as becoming, can be provided.

Meanwhile, FIG. 6 is a partially enlarged cross-sectional view showing a state before Hume pipes adjacent to each other are bound by the watertight ring 100 according to another embodiment of the present invention, and FIG. 7 is a partial enlarged cross-sectional view of Hume pipes adjacent to each other in FIG. This is an enlarged section of the state.

For reference, in describing the watertight ring 100 according to another embodiment of the present invention, the same reference numerals are assigned to the same parts as in the previous embodiment, and repeated description thereof will be omitted.

Referring to FIGS. 6 and 7 , in the watertight ring 100 according to another embodiment of the present invention, at least one rib 160 may protrude from the seating part 130 .

When the first Hume pipe 10 and the second Hume pipe 20 are bound, the rib 160 maintains a state in close contact with the inner circumferential surface 22a of the socket portion 22 of the second Hume pipe 20, When the primary watertightness is released by the close contact part 140 due to a misalignment between the binding parts of the first Hume pipe 10 and the second Hume pipe 20, it is possible to perform a function of making watertightness auxiliary.

In this way, in the case of the watertight ring 100 having one or more ribs 160 formed on the seating portion 130, it further performs an auxiliary watertight function, and other configurations and operational effects are a watertight ring according to the previous embodiment ( 100), the description of the operation relationship will be omitted.
