Description

Corrugated steel pipe used manhole}

The present invention relates to a manhole in which a corrugated steel pipe is used, and more particularly, in forming the body of the manhole, the inner tube is combined with a filler in the inside of the corrugated steel pipe to firmly support the surrounding earth pressure, while using the same steel pipe as the body. Waveform that prevents leakage by welding the formed inlet pipe and outlet pipe by welding, and at the same time has an inlet pipe and an outlet pipe combined with a rubber ring so that it can be firmly coupled with neighboring pipes without additional equipment at the construction site. It relates to a manhole in which steel pipes are used.

Manholes are structures for checking sewage pipes, dredging or repairing pipes.

Usually, the manhole consists of an upper cover installed on the upper part of a body made of concrete and a lower cover installed on the lower part.

In addition, the body is provided with an inlet pipe and an outlet pipe connected to neighboring pipes.

Manhole bodies made of concrete are generally used because they are inexpensive and can withstand large earth pressure.

However, the manhole body formed of concrete is not only difficult to install due to its heavy weight, but is also vulnerable to impact and is frequently damaged during installation.

In addition, when the height of the manhole body is high, it is difficult to fabricate the body into one due to the nature of the concrete material, so a method of combining several bodies is taken.

However, this has been pointed out as a problem due to leakage of water in the coupling part.

In order to solve this problem, a fiberglass body is being manufactured.

The fiberglass body is lighter than the concrete body and can be manufactured integrally.

However, the fiberglass body is expensive, and it is classified as industrial waste in particular, causing environmental pollution.

Meanwhile, in the conventional manhole body, the inlet pipe and the outlet pipe are bonded with an adhesive or fixed with a clamp. As a result, water leakage occurs in the inlet pipe and outlet pipe, which is pointed out as the main culprit for polluting the soil.

Therefore, it is possible to firmly support the earth pressure around where the manhole is installed, and at the same time, it can be manufactured as an integral part to prevent leakage, and it is light, so that the convenience of installation work is increased, and the risk of damage due to high impact resistance can also be reduced. There is an urgent need to develop a manhole with a new structure that can be firmly coupled with neighboring pipes at the construction site without equipment.

1 is a perspective view of a manhole using a corrugated steel pipe according to a first embodiment of the present invention, FIG. 2 is an exploded view of a manhole using a corrugated steel pipe according to a first embodiment of the present invention, and FIGS. It is a cross-sectional view of a manhole in which the corrugated steel pipe according to the first embodiment of the invention is used.

This will be described with reference to FIGS. 1 to 4.

The first embodiment of the manhole according to the present invention includes a body 100, an upper cover 400, a lower cover 500, an inlet pipe 200, and an outlet pipe 300.

The body 100 has an opening formed in the upper portion and a space portion formed therein to store sewage or sewage.

An inlet is formed on one side of the body 100 and an outlet is formed on the other side.

Typically, the height of the outlet port is formed lower than the inlet port so that the introduced fluid flows out smoothly.

The upper cover 400 is configured to open and close an entrance to which a worker enters and exits for inspection or maintenance work.

The upper cover 400 is coupled to the upper portion of the body 100 so as to be removable.

In FIGS. 3 and 5, the lower cover 500 is coupled to the lower part of the body 100, but may be formed in a structure in which the lower part of the body 100 is closed without the lower cover 500.

The inlet pipe 200 is coupled to an inlet formed on one side of the body 100 to form a flow path of sewage or rainwater to be introduced.

The outlet pipe 300 is coupled to an outlet formed on the other side of the body 100 to form a flow path of sewage or rainwater to be discharged.

In the prior art, in consideration of low manufacturing cost and good support for large earth pressure, the manhole body 100 was mainly made of concrete. However, not only the installation work is difficult due to its weight, but also the case of being damaged due to the impact frequently occurred.

Accordingly, in the present invention, in manufacturing the manhole body 100, the corrugated steel pipe 110 is disposed on the outside, and the inner tube 120 is integrated with the filler 130 inside the manhole body 100.

The structure of the manhole body 100 will be described in detail.

The corrugated steel pipe 110 disposed outside the manhole body 100 is formed of a steel plate in a circular pipe shape.

The manhole body 100 is formed in a spiral shape with respect to the longitudinal direction of the body 100 in a waveform consisting of a convex portion and a concave groove in the thickness direction.

The corrugated steel pipe 110 not only increases the strength of the steel pipe itself, but also increases the strength of the corrugated structure in the thickness direction so that it can sufficiently withstand the surrounding earth pressure.

In addition, the corrugated steel pipe 110 is light, so that installation workability is increased, and it is strong against impact and thus reduces the risk of damage.

Furthermore, it exhibits good seismic performance even in the case of earthquakes that occur frequently these days.

An inner tube 120 is inserted into the corrugated steel tube 110.

As the material of the inner tube 120, it is preferable to adopt an appropriate material according to the use of synthetic resin, concrete, cast iron, and stainless steel.

That is, the inner tube 120 made of an appropriate material may be adopted according to the temperature, corrosion, and pollution degree of the fluid flowing through the inner tube 120.

A filler 130 is filled between the inner surface of the corrugated steel pipe 110 and the outer surface of the inner tube 120 to integrate the corrugated steel pipe 110 and the inner tube 120.

In addition to the purpose of fixing the corrugated steel pipe 110 and the inner pipe 120, as the filler 130, it is preferable to adopt mortar, gypsum, insulation, etc. according to the purpose in consideration of strength, watertightness, construction convenience, heat loss prevention, etc. .

In summary, the corrugated steel pipe 110 on the outer surface of the manhole body 100 plays a role in withstanding an external load, and the inner pipe 120 plays a role in responding well to the characteristics of the flowing fluid.

The manhole body 100 according to the present invention is made of a corrugated steel pipe 110 so that it can be integrally manufactured even at a fairly high height, thereby solving the problem of leakage.

The structure of the inlet pipe 200 and the outlet pipe 300 will be described.

The inlet pipe 200 and the outlet pipe 300 according to the present invention include a corrugated steel pipe 260 for flow, an inner pipe 250 for flow, and a filler 270.

The corrugated steel pipe 260 for flow is formed of a steel plate in a circular pipe shape, and a corrugation consisting of a convex portion and a concave groove in the thickness direction is formed in a spiral shape with respect to the length direction. This has the same structure as the manhole body 100.

The flow inner pipe 250 is formed in a circular pipe shape and is inserted into the flow corrugated steel pipe 260.

A filler 270 is filled between the inner surface of the flow corrugated steel pipe 260 and the outer surface of the flow inner tube 250 to integrate the flow corrugated steel pipe 260 and the flow inner tube 250.

In addition to the purpose of fixing the corrugated steel pipe 110 and the inner pipe 120, as the filler 130, it is preferable to adopt mortar, gypsum, insulation, etc. according to the purpose in consideration of strength, watertightness, construction convenience, heat loss prevention, etc. .

Referring to FIG. 3, the front end of the flow inner tube 250 is exposed to the front end of the flow corrugated steel tube 260 with a predetermined length.

And the rubber ring 210 is fixed to the outer circumferential surface of the flow inner tube 250 exposed to the front end of the flow corrugated steel pipe 260.

The exposed inner pipe 250 for flow is inserted into the neighboring pipe 600, and at this time, the rubber ring 210 mounted on the outer circumferential surface of the inner pipe for flow 250 is inside the neighboring pipe 600. It is forced in.

Since the inlet pipe 200 and the outlet pipe 300 are manufactured in such a structure, it is possible to be firmly coupled to the neighboring pipe 600 without additional equipment.

Conventionally, when combining the inlet pipe 200 and the outlet pipe 300 with the neighboring pipe 600, the filler 270 was applied to the coupling portion and tightened with a clamp.

However, in order to supply the filler 270 such as mortar at the construction site, separate equipment is required, resulting in poor workability, and there is a problem of leakage due to a decrease in the clamping force of the clamp.

On the outer circumferential surface of the inner tube for flow 250, a waveform composed of a convex portion and a concave groove may be formed in a spiral shape with respect to the longitudinal direction.

This serves to firmly support the rubber ring 210 wound on the exposed portion, and at the same time, increases the surface area of the outer circumferential surface of the inner tube 250 for flow, thereby increasing the fixing force by the filler 270.

In the related art, water leakage frequently occurred in a portion where the inlet pipe 200 and the outlet pipe 300 are coupled to the body 100.

In the present invention, the outer surface of the manhole body 100 and the inlet pipe 200 and the outlet pipe 300 are formed of the same steel pipe. Therefore, welding, which was not possible in the case where the manhole body 100 is formed of concrete or fiberglass in the prior art, is possible, and a leakage problem that occurs in a portion where the inlet pipe 200 and the outlet pipe 300 are coupled to the body 100 Was resolved at once.

5 is a cross-sectional view of a manhole in which the corrugated steel pipe 110 according to the second embodiment of the present invention is used.

This will be described with reference to FIG. 5.

The second embodiment of the present invention is an embodiment in which the structure in which the flow inner pipe 250 is coupled to the flow corrugated steel pipe 260 is modified.

In the first embodiment of the present invention, the flow inner pipe 250 is formed in a structure exposed to the flow corrugated steel pipe 260, but in the second embodiment, the flow inner tube 250 is inside the flow corrugated steel pipe 260. It has a structure that is inserted into.

The front end of the flow inner tube 250 is arranged to be inserted into the inside by a predetermined length with respect to the front end of the flow corrugated steel pipe 260, and a rubber ring 210 is fixed on the inner circumferential surface of the front end of the flow corrugated steel pipe 260 The rubber ring 210 was forcibly fitted to the outer circumferential surface of the pipe 600 to be coupled.

The present invention relates to a manhole in which the corrugated steel pipe 110 is used, and more particularly, in forming the body 100 of the manhole, by combining the inner tube 120 with the filler 130 inside the corrugated steel pipe 110 While firmly supporting the surrounding earth pressure, water leakage is prevented by welding the inlet pipe 200 and the outlet pipe 300 formed of the same steel pipe as the body 100, and at the same time, the rubber ring 210 is combined. It relates to a manhole in which a corrugated steel pipe 110 provided with an inlet pipe 200 and an outlet pipe 300 so that it can be firmly coupled with a neighboring pipe 600 without additional equipment at a construction site.

In the above, preferred embodiments of the present invention have been illustrated and described, but the present invention is not limited to the specific embodiments described above, and the present invention is generally in the technical field to which the present invention belongs without departing from the gist of the present invention claimed in the claims. Of course, various modifications may be implemented by those skilled in the art, and these modified embodiments should not be individually understood from the technical spirit or prospect of the present invention.
