Description

{ASSEMBLED SEALING GASKET BODY FOR MANHOLE STRUCTURE}

The present invention relates to a prefabricated underground structure piping system, and more particularly, to a prefabricated piping structure for an underground special structure, Since the line pipe can be more firmly and tightly sealed, it is possible to surely secure the exponent in the pipeline, and the air and the antifreeze tube ring body capable of injecting the air and the antifreeze can be very quickly combined with the pipeline structure of the underground structure. The present invention also relates to a prefabricated high-pressure underground structure prefabricated pipe, which is easily compatible with a prefabricated pipe, thereby reducing maintenance costs.

In general, a pipe line is an entrance of a pipe for attaching a power line to the inside of an underground structure, if necessary, attached to a side wall of an underground structure used for electric power wiring. In the conventional pipe line connection structure, And a tube lid having a male screw portion is screwed to the female screw hole on the other side so that the tube lid is screwed to the female screw hole on the one side of the female screw hole. And the concrete pipe and the lid cover are screwed to the female screw portion formed on both sides of the adapter in a state where the adapter is installed on the wall of the underground structure through the operation such as concrete pouring.

In the conventional pipe coupling structure, since the concrete is attached to the female threaded portions of both sides of the adapter in the process of installing the adapter on the wall of the underground structure, not only screwing of the pipe passage and the pipe lid into the female threaded portion is easily performed, It is difficult to ensure the exponential property in the pipe liner because the screw connection state is not stable. Also, since the materials of the concrete poured around the adapter are different from each other, they are not firmly attached to each other. In some cases, There is a lot of problems such as the penetration of water outside the underground structure between the concrete.

In order to solve such a conventional problem, a tube having an outer thread portion is formed with a fastening protrusion protruding at a predetermined interval at one side and vertically bent to the outside, and a fastening hole is formed in the fastening protrusion, An inner thread portion threadedly engaged with the outer threaded portion of the tube body is formed at the inner periphery of the tube body and is positioned on each of the right and left sides of the underground structure tube hole, A left and a right support panel having fastening holes formed on an extension line of the fastening hole, respectively, and a rubber member of a rubber material positioned between the left and right support panels and the underground structure, A concave-convex sealing portion is repeatedly formed and sealed in a surface facing the underground structure, A fastening hole through which fastening holes of the fastening protrusions of the left and right support panels are inserted into the fastening holes of the right and left support panels and which are fastened and fixed by fastening nuts, A right ring-shaped panel formed with a connecting hole formed on an extension of the fastening hole with a metallic material ring inserted into the insertion recess of the right support panel and closely contacted with the fastening protrusion, A plurality of ball rings positioned between the left and right tight packing and sealing the space between the right and left packing by forming a bolt hole through which the bolt penetrates, And a ball which is located between the ball-and-socket ring and between the left and right tight packing and inflates the volume inside to have an elastic force, And a tube ring formed with a bolt insertion hole through which the injection space portion and the fastening bolt are inserted to seal the space between the left and right tight packing and the pipeline which is a space between the pipeline body and the underground structure. "Has been disclosed in Patent Registration No. 10-0786561.

However, in the assembled type pipe of this kind, it is very easy to join the pipe lid and the pipe lid, and the pipe lid can be firmly adhered to the underground structure of the concrete material, so that the index in the pipe lid can securely be ensured. On the other hand, The diameter of the pipe passage 81 of the underground structure 80 or the diameter of the pipe body 10 and the diameter of the pipe body 10 are required to be sealed, There is a problem in that a prefabricated duct is required to be separately provided.
