The present invention relates to a method of joining a water pipe and a manhole using a water-expandable rubber index ring, and more particularly, a water-expanded rubber index formed with an inner circumferential surface according to the shape of the outer circumferential surface of the water pipe used as the main pipe or single pipe for the water pipe. The present invention relates to a method of joining a water pipe and a manhole using a water-expandable rubber water ring to provide a perfect water structure by fastening a ring to an water pipe.

The water-expanded rubber index material refers to rubber having a volume expansion rate by absorbing moisture, and is currently known to have a volume expansion rate of several times its own volume. At present, sheet-type water-expandable rubber index materials have been mass-produced for use as watertight materials, and are used for watertight treatment of sewage pipes and drain pipes.

And water pipe is watertight treatment to prevent the water filled in the manhole from leaking out of the manhole and pipe from the manhole when sewage pipe or drain pipe is connected to the inlet or outlet of the manhole and to prevent unnecessary flooding from the outside. By means of pipe coupled to the manhole.

When sewage pipes are coupled to the manhole, there are differences depending on the construction method.However, in the construction process of the manhole where the coupling holes are formed or do not undergo hardening by concrete pouring at the time of construction, the pipes are drilled in the lower part of the manhole. Form a site for binding.

On the other hand, the formwork for the shape of the manhole is made, and concrete is poured into it to form a manhole. At this time, a construction method of combining pipes is used.

Conventionally, as a method of joining a water pipe to a manhole, in a construction in which a manhole is constructed by concrete pouring, a water pipe using a steel or non-expandable rubber water pipe is joined to a pipe to combine the water pipe. This method is useful for combining manholes and exponential pipes at the time of construction by combining concrete, but the perfect index due to leakage at the joints of the joints due to the difference in dry shrinkage of concrete and binders after concrete placement. It is difficult to get a state.

However, due to economical aspects such as shortening of the air and ease of construction, many manholes are already used for construction, and pipe fittings are formed at the lower side, It should be drilled and used.

There was a problem that the perfect index is not secured when the index pipe is combined by selecting such a construction method. In such a construction method, a sheet- or tape-type water-expandable rubber index member is used in the construction method, but it is difficult for economic reasons to wind up the sheet- or tape-type index member so as to fit into the coupler.

In this construction method, the tape- or sheet-shaped index member is placed on the outer circumferential surface of the pipe, and then introduced into the coupling hole of the manhole, and the mortar reinforcement is poured between the coupling hole and the coupling.

The problem with this construction is that the reinforcement hardens and then leaks into the voids formed between the original coupler and the reinforcement. This causes leakage of wastewater flowing in the manhole and causes water pollution in public waters as a cause of groundwater pollution.In addition, unnecessary groundwater from outside penetrates through these gaps, thus increasing unnecessary throughput in sewage treatment plants. This acted as a problem of improper operation.

In order to solve the above problems, in order to effectively use the construction method by concrete pouring or the ready-made products of manholes, a shape corresponding to the outer circumferential surface of the water pipe is formed on the inner circumferential surface of the ring so that it can be easily combined with the water pipe. Invented the ring and the method for the manhole index.

In accordance with one embodiment of the present invention, the leaked water in the manhole coupling portion of the sewage pipe or drain pipe by the coupling of the manhole and the water pipe formed with the coupling hole or the coupling hole is formed by perforation according to an embodiment of the present invention. The purpose is to ensure that is completely prevented.

In addition, the object of the present invention is to provide a fastening method such as a nut or a simple fastening method such as a ring.

In addition, it is an object to be able to save the cost by allowing the concrete structure added around the coupling hole of the manhole to perfect the watertight treatment.

In addition, it is an object of the present invention to be usefully used in a construction method in which the piping and manhole composition are simultaneously formed by concrete pouring.

According to an embodiment of the present invention in order to solve the above object, the water pipe is configured using the main pipe or the single pipe of the sewage pipe or the drain pipe. At this time, the material of the water-expanded rubber index ring for use in the joining method of the water pipe and the manhole using the water-expanded rubber index ring is made of cylindrical shape by using the water-expanded rubber index material.

 Recently, in order to reinforce the adaptability to external pressure as a pipe, a steel plate is embedded in the pipe, a pipe is manufactured by forming a spiral wave shape, and when the outer circumference is formed into a smooth surface, reinforced plastic is used. In order to facilitate coupling to such a pipe, the inner circumferential surface of the present invention forms a spiral or a smooth surface corresponding to the outer circumferential surface of the pipe.

The outer circumferential surface of the water-expandable rubber index ring used in the present invention is a portion where the upper surface portion and the outer circumferential surface are rounded in order to facilitate the retracting when entering into the coupling hole of the manhole so that the outer diameter of the upper surface portion is smaller than the outer diameter of the lower surface portion. In general, the configuration in the shape of a truncated cone corresponds to the preferred embodiment.

Conventionally, there has been a method of forming a water pipe using a tape or sheet-like water-based material using water-expandable rubber water-based material, but in such a construction method, water leakage is prevented from occurring due to the gap formed between the reinforcing material and the coupling hole of the manhole. In order to prevent leakage of water around the inner and outer wall joints of the manhole, a method of adding concrete or fusing polyethylene resin was used.

This method has become a problem of producing poor sewage pipes by inducing the toxic and corrosive waste water to be separated between the joints and the reinforcement or the polyethylene resin or reinforcement concrete formed on the inner and outer walls of the manhole. Therefore, the present invention is to facilitate the construction by the ring and method for the manhole index, and at the same time can be easily carried out in the composition of the manhole using a ready-made product or formwork.

In particular, the ring used in the index pipe for the index of the manhole is to expand to the existing coupling sphere to overcome the above factors caused the leakage between the coupling sphere and the reinforcement.

Hereinafter, a detailed description according to an embodiment of the present invention will be described with reference to the drawings.

1 is a view showing an example of coupling a manhole and a water pipe conventionally carried out.

Referring to FIG. 1, a coupling hole is formed in the manhole 30, and a pipe including the water pipe 20 in the form of a sheet or tape is formed in the pipe to form the water pipe 20. It is a method in which the mortar reinforcement 40 is placed between the coupler and the water pipe and the concrete reinforcement 60 is formed again to prevent leakage of water between the reinforcement and the coupler. In this construction method, the size of the splices to be drilled is formed to about 150% of the outer diameter of the index pipe with the index material and the reinforcement is to be placed around it. There is a problem of increasing costs. In addition, even in this construction, the gap between the coupling and the reinforcement due to the characteristics of the concrete and the main material due to the difference in shrinkage and expansion due to the external temperature, the voids are generated, and the pollution is severe and the toxic wastewater is penetrated by the bad sewage pipes often.

Referring to Figure 2, as a method for solving the problems in the prior art, the ring 10 for the exponent of the manhole 30 is coupled to the water pipe 20, the exponent ring is coupled to the manhole It can be seen that the shape is sufficiently inflated to the sphere 34 and completely in contact with the coupling sphere. The portion where the coupler 34 and the outer circumferential surface 16 of the index ring meet is filled with water-expandable rubber even in the minute gap formed along the irregular surface of the concrete, so that the index through this portion is completely completed.

3 is a diagram illustrating a time when the manhole 30 is formed by placing concrete. When the water ring is combined with the water pipe 20 and the water pipe is formed, the concrete is poured and then when the concrete is hardened, the outer surface of the water-expandable rubber water ring is in contact with the concrete and expands irregularly and is perfect. Exponents,

As described above, the present invention has properties that can be usefully used both in the manufacture of manhole manufactured articles and concrete manholes.

Referring to Figures 5 and 6, Figure 5 is a view showing a shape that forms a screw on the inner circumferential surface 14 of the ring for the index of the manhole according to an embodiment of the present invention and such a cross section 12 6, the inner circumferential surface 14 has a smooth shape, and the shape can be understood as seen in the cross-section 12.

In order to facilitate the coupling when the water-expandable rubber index ring as described above is coupled to the index tube, the outer circumferential surface of the index tube and the inner circumferential surface of the ring are preferably used after lubrication.

As described above, the present invention has a structure to solve the problem of water leakage that can occur between the reinforcing material and the coupler in the prior art.

In addition, the construction method has the advantage that can be omitted to reinforce the concrete used in the prior art to the outer wall of the manhole, the step of combining the water-expanded rubber index ring for the manhole index to one end of the index pipe and the index to the manhole Drilling a coupling hole of a manhole having an inner diameter plus a thickness of a water-expandable rubber index ring for a pipe and an index; introducing the index tube into a coupling hole drilled in the manhole; and a number of rings for the manhole index And expand and completely adhere to the coupling holes of the perforated manholes.

According to one embodiment of the present invention as described above, the watertight treatment is completely secured to the manhole coupler so that leakage water does not occur in the coupler portion unnecessarily. This prevents contaminated water in the manhole from entering the groundwater and contaminating the environment and drinking water.

It also prevents unnecessary increases in the sewerage system, thereby avoiding unnecessary disposal in sewage treatment plants that apply these rings and methods for manhole indexes, resulting in saving resources.

In addition, by applying the water-expandable rubber index ring used in one embodiment of the present invention to the construction method of combining the manhole and the index pipe, it is possible to shorten the overall air and reduce the manpower by simply coupling structure.

In addition, there is an economic effect that can save the raw materials, such as important and expensive concrete by avoiding the conventional construction method that resulted in poor construction results by the water-tight treatment in the field.
