The present invention relates to a pipe coupler connected to the manhole and a construction method thereof, and more particularly, the pipe coupler consists of two joints, which is easy to assemble, and requires a separate perforation work to the formwork or the manhole body. The present invention relates to a pipe joint and a method for constructing the same, which can be easily installed and can completely prevent leakage of waste water, thereby preventing environmental pollution.

The manhole is a hole installed in the middle of a place where the thickness or direction of the sewer pipe changes, a starting point, an intersection point, or a long straight portion, and is a hole that allows people to enter and exit the road surface for repair and construction. The shape of the manhole is the most easy to construct a circle, and there are also square and oval. The entrance is framed with a steel frame or stone around it and covered with a round lid of cast iron or reinforced concrete, usually about 60 cm in diameter. The body is made of concrete or brick, and the inner diameter of the passage hole is often 0.9 to 1.2m. The bottom is equivalent to the bottom of the pipeline, or slightly lowered to accommodate the sediment.

The side wall of the manhole as described above is connected to the pipe so that rainwater or waste water flows. The manhole is formed after the construction of a round or square formwork to pour concrete to form a main body, and after drilling the pipe joints on the side wall, using a fastener and the like to connect the pipe and the manhole body.

1 shows a conventional piping structure according to Korean Utility Model Registration No. 20-0426776, and FIG. 2 shows a state in which such a piping structure is connected to a manhole body. As shown in the drawing, a conventional pipe connection structure includes a plurality of through-holes formed at one end of an outer surface of a manhole, formed of at least one multi-stage portion at the through surface, and a plurality of anchors formed at the outermost end of the multi-stage portion. Manhole body 20 consisting of 30, the pipe 40 is formed in one end portion is inserted into the pipe coupling hole 30 and the outermost end in contact with the outermost end of the pipe 40, the pipe ( It is configured to include a rubber packing 50 which is installed between the disk protrusion 41 and the outermost end of the pipe coupling hole 30 formed on the outer circumferential surface of the 40.

However, in such a conventional pipe connection structure, first form the formwork to make the desired manhole shape, and then cast concrete on it to produce the manhole body 20, and then the curing and curing of the concrete is completed, Perforate the pipe joint hole 30 formed in multiple stages on the outer wall of the manhole body 20 separately, and inject the anchor nut into the manhole body or drive the anchor groove to drive the anchor bolt even when the pipe 40 is coupled to the manhole body. Perforated. Since the manhole body is made of concrete, the perforation or perforation work and the anchoring work are very demanding, and the construction of the manhole body may cause cracks in the periphery of the perforation, and the construction of the manhole body may be inefficient.

Due to these problems, after the manhole body is manufactured, the pipe is inserted into the formwork from the beginning when the manhole body is manufactured, and the concrete is poured by forming the manhole body. Construction methods have also been developed. 3 shows the structure of the formwork M in which the pipe is joined from the beginning according to this conventional construction method.

According to the conventional construction method as described above, although it is convenient because there is no need to drill a separate pipe joint hole on the outer wall of the pre-manufactured manhole body, it is made of metal or the like to insert the pipe after manufacturing the formwork. There is still an inconvenience of having to perforate the outer wall of the formwork, and even when trying to combine the pipe and the manhole body with anchor bolts, there is still a problem that a separate anchor groove must be perforated in the manhole body made of concrete. .

On the other hand, the pipe thickness is slightly different according to the pipe production company within the tolerance range of the pipe thickness, there is an inconvenience to be attached to the production by varying the thickness of the rubber packing according to the thickness of the pipe to be constructed. In most construction sites, it is very cumbersome to manufacture a separate rubber packing with different thickness at that time, so most of the pipes are already made of a certain thickness regardless of the pipe thickness. However, in this case, since the rubber packing does not effectively seal the leakage occurs, there is a problem that causes a serious environmental pollution (soil pollution) in the waste water pipe.

Therefore, the present invention was devised to solve the problems of the manhole and the pipe connection structure according to the prior art as described above, manhole body and formwork outer wall do not need to separate pipe fittings, manhole made of concrete There is no need to drill anchor grooves in the main body, so the construction is simple and easy to assemble, and it is an object of the present invention to provide a pipe joint and a construction method that can prevent environmental pollution by preventing complete leakage.

Hereinafter, a pipe coupler and a construction method thereof according to the present invention with reference to the accompanying drawings will be described in detail.

4 is a perspective view of a pipe fitting according to the present invention constructed in a manhole body, FIG. 5 is an exploded view of a pipe fitting according to the present invention, FIG. 6 is a rear perspective view of a first joint of a pipe fitting according to the present invention, and FIG. 8 is a plan sectional view of the first joint of the pipe fitting according to the present invention, FIG. 8 is a plan sectional view of the second joint of the pipe fitting according to the present invention, and FIG. .

As shown in Figures 4 to 9, the pipe fitting according to the present invention is composed of a first joint 100, a second joint 200, rubber packing (50).

The first joint 100 is introduced into the form (M) at the time of manufacturing the manhole body 20, and is poured into the concrete, the manhole body 20 is formed at the same time coupled to it and connected to the pipe is formed into the manhole The wastewater or the like flowing from the other pipe of the rainwater or the manhole body 20 to be distributed to the other pipe.

As shown in FIGS. 4 to 7, the first joint 100 has a substantially tubular shape, and a first flange 102 is formed at one end thereof. The tubular portion of the first joint 100 is embedded in the outer wall of the manhole body 20 formed by concrete pouring, and the first flange 102 is exposed to the outer wall of the manhole body 20 to be described later. Is fastened with 200.

In order to fasten with the second joint 200, a plurality of anchor sockets 106 are formed in the first flange 102. The anchor socket 106 is a portion into which the anchor bolt 60 is inserted for fastening with the second joint 200. The anchor socket 106 is formed integrally with the first flange 102 by the injection method. Accordingly, when the first joint 100 is injected into the mold M and concrete is poured, the tubular portion and the anchor socket 106 are embedded in the concrete and firmly coupled thereto, and the concrete inside the anchor socket 106 is concrete. There is no input is secured the space portion that can be inserted into the anchor bolt 60 is fastened.

Conventionally, because the anchor bolt 60 should be coupled to the manhole body 20 made of a concrete material, the anchor hole 60 had to be drilled separately in the manhole body 20. However, according to the present invention, since the anchor socket 106 is integrally formed on the first flange 102, it is not necessary to drill a separate anchor groove in the concrete, thereby facilitating the fastening operation.

A fixed blade 104 is provided on the outer side of the anchor socket 106. The first joint 100 is generally composed of a synthetic resin, such as polyethylene, synthetic resin and concrete is generally weak adhesive force, the first joint 100 is a synthetic resin is not firmly attached to the manhole body 20 made of concrete There is a risk of deviation from the manhole body 20 in the horizontal direction. Therefore, in the present invention, it protrudes from the outer side of the anchor socket 106 to form the fixed blade 104 integrally over the circumference of the first joint (100). The fixed blade 104 thus formed is embedded in concrete because the first joint 100 protrudes perpendicularly to the direction in which the first joint 100 is fitted to the manhole body 20, that is, perpendicular to the longitudinal direction of the tubular portion of the manhole body 20. The first joint 100 serves to fix the first joint 100 in a horizontal direction.

The second joint 200 is connected to the outside of the first joint 100. The second joint 200 is a portion to which a pipe for distributing waste water, which flows in or out of the manhole, is connected.

As shown in FIGS. 5 and 8, the second joint 200 has a tubular portion, like the first joint 100, and has a second end coupled to the first flange 102 at one end thereof. Flange 202 is formed. A fastening hole 204 corresponding to the openings of the anchor socket 106 formed in the first flange 102 is formed in the second flange 202, and the anchor bolt 60 is formed through the fastening hole 204. It is inserted through.

A rubber packing 50 is installed between the first joint 100 and the second joint 200 to prevent leakage of waste water from the joint portion when the joints are connected. To this end, a packing groove 206 is formed at the outer circumference of the opening of the second flange 202 so that the rubber packing 50 can be inserted and mounted.

When the first joint 100 and the second joint 200 are coupled, the rubber packing 50 is inserted into the packing groove 206, and then the flanges of the first joint 100 and the second joint 200 are inserted into the packing groove 206. Fasten them together with anchor bolts (60). Through this configuration, leakage of waste water is prevented and assembly of the pipe connection part is completed simply. Thus, since the rubber packing suitable for pipe fittings having a certain thickness is manufactured and installed, there is no need to produce a separate rubber packing thickness according to the thickness of the pipe, and the leakage of waste water is blocked by the perfect sealing action of the rubber packing. Environmental pollution (soil pollution) can be prevented.

9 is a plan sectional view showing a coupling structure of the pipe fitting according to the present invention.

As shown, the tubular portion and the anchor socket 106 portion of the first joint 100 are embedded in the manhole body 20, and the first flange 102 is exposed outside the manhole body 20. . As the second flange 202 is abutted and the anchor bolt 60 is fastened to the outside of the first flange 102, the second joint 200 is coupled.

The tubular end of the first joint 100 and the first flange 102, and the second flange 202 of the second joint 200 are deformable according to the curved surface of the manhole body 20. That is, in the case of using the square manhole body 20, the tubular end of the first joint 100, the first flange 102, and the second flange 202 correspond to the surface shape of the square manhole body 20. It is usually straight. However, in the case where a circular manhole is used (a circular manhole is used for most waste water pipes), as shown in FIGS. 5 to 9, the curved shape corresponding to the curved shape of the circular manhole body 20 is formed, that is, rounding treatment. It is desirable to be. In addition, in the case of the manhole body 20 formed of polygons or ellipses, the flange shape and the tubular end of the first joint are deformed and manufactured to correspond to the surface bending shape of the manhole body 20.

The first joint 100 and the second joint 200 as described above are manufactured by an injection method. In this case, corning portions are formed in the tubular portions of the first joint 100 and the second joint 200, respectively. Corning is the so-called fat loss process, which involves welding steel to a mold in order to reduce or remove material from certain parts of the part in the injection molding process. In general, shrinkage occurs due to insufficient cooling before release from the mold, which is most likely when thick ribs are designed for thin-walled products. To solve this, you will lose weight. In the present invention, it is preferable to prevent shrinkage by losing weight on the tubular portions of the first and second joints 200.

So far, the configuration of the pipe connector according to the present invention has been described. Hereinafter, the construction method of the pipe connector according to the present invention will be described in detail.

In this case, the first joint 100 is made of a predetermined dimension to fit the gap between the inner mold of the mold (M) and the inner wall of the outer mold, and both sides and the maximum of the mold (M) and the first joint (100) It is desirable to prevent the play from occurring so that the concrete blocks the opening of the first joint. The first joint 100 should be inserted so that the first flange 102 faces outward.

After the first joint 100 is put into the formwork M, concrete is poured into the formwork M and cured and cured. When curing and hardening of the concrete is completed, the formwork M is dismantled. In this way, the manhole body 20 is formed, and both sides of the manhole body 20 are fixedly installed with the first joint 100 embedded therein. Therefore, no additional punching work is required for the formwork M or the manhole body 20.

After the manhole body 20 is manufactured, the rubber packing 50 is formed in the packing groove 206 formed in the first flange 102 of the first joint 100 and / or the second flange 202 of the second joint 200. ) And then join the second joint 200. The second joint 200 is positioned in the anchor socket 106 formed integrally with the first joint 100 after the second flange 202 is positioned to face the first flange 102 of the first joint 100. It is coupled by fastening the anchor.

Construction of the pipe fitting is completed in the same manner as above, which is shown in cross-sectional view in FIG. When extension of the pipe is required, a separate pipe may be connected to the outside of the tubular portion of the second joint 200 in a conventional manner.

So far, the present invention has been described in detail with reference to embodiments of the present invention. However, the scope of the present invention is not limited thereto, and the present invention is intended to include practically equivalent ranges.
