The present invention relates to an inverted manhole integrated with a pipe connection socket, in particular, the connection socket provided for connection with the pipe (pipe) on the inlet / drainage side of the manhole is to be integrally formed in the manhole by concrete pouring during the first manhole production. In addition, it is not necessary to install a separate connection socket for pipe connection, and thus relates to a pipe connection socket integrated inverted manhole to improve the cost savings and mass productivity according to the manhole production.

A manhole is a facility that allows people to enter and check the underground sewage pipes, water pipes, underground cables, and pavement, etc., where the thickness or direction of the pipe changes, the starting point, the intersection point, and the middle of the long straight part. Is installed on. The installation distance of such a manhole is about 50-100 m or 100-150 m, and is usually provided just above a conduit.

As shown in FIG. 1, the conventional manhole has an inlet 110 and a drainage hole 120 formed at a side of an open manhole 100, and a slab having a manhole hole 210 formed thereon. It is made to open and close the manhole hole 210 with the manhole cover 300 in the seated state, the bottom of the manhole 100 to prevent hydraulic losses due to the rapid cross-sectional expansion / reduction of the inlet / outlet pipe 130 is formed.

The invert 130 is a bottom structure of the manhole which is installed for the purpose of preventing or preventing odor generated by sediment mixed with sewage introduced into the manhole and smoothing the flow of sewage. It is made to include a waterway of the size corresponding to the lower half of the inlet and outlet pipes (P) are respectively installed in the outlet 120 and.

On the other hand, the inlet / drain outlets 110, 120 of the manhole is connected to the inlet and outlet pipes are connected to the wastewater inlet / outlet pipe (hereinafter referred to as "piping") is connected to the socket 140, The inlet socket 140 is in communication with the invert 130 and the front end of the pipe (P) is fitted so that the waste water flows, and for connecting with the connection port to prevent the leakage of sewage formed in the rear end of the expansion step The rubber packing 150 is fitted. In the rear of the rubber packing 150, the flange 160 is fastened to the connector socket 140 as a bolt B to fix the pipe P including the rubber packing 150 to the connector socket 140.

Here, the connection socket 140 is generally made of a synthetic resin material such as plastic, the inner diameter is formed stepped so that the front end of the pipe and the pipe stepped portion formed on the end is formed stepped and exposed to the outside of the manhole In the circumferential direction of the (fore) face, the bolting hole 142 is drilled at equal intervals.

When installing the connector socket 140 on the drain hole and the water inlet side of the manhole, first, by forming concrete, the diameter of the inlet / drainer is made larger than the diameter of the outlet socket by manufacturing the manhole, and then the outlet socket on the inlet / drainer. Insert 140. Next, by injecting the mortar 170 and the like into the space formed due to the diameter difference between the inlet / drainer and the outlet socket, the outlet socket may be embedded in the inlet / drainer of the manhole.

However, in the related art, since the manhole and the connection socket are composed of separate components, as described above, when manufacturing the manhole, the connection socket had to be manufactured separately and then fixed to the inlet / drainage side of the manhole with a mortar. In addition, there is a problem that the assembly and mass production is poor, and in particular, when the injection of the mortar that fixes the connection socket to the inlet / drain of the manhole is poor, the seal between the inlet socket and the inlet / drain of the manhole is completely sealed. There is a problem such that the gap is generated and the waste water leaks through the gap to contaminate the surrounding ground and destroy the environment.

The present invention has been made in view of the conventional problems as described above, and when the first inverted manhole manufacturing a connection socket for connection with pipes (pipes) on the inlet / drain side formed through the side wall of the manhole It is formed by, so as to eliminate the need to install a separate connection socket for the pipe connection to improve the cost savings and mass productivity of the manhole inverter manufacturing, eliminating the factor of the generation of gaps with the manhole inverter due to the installation of the socket socket The purpose is to provide a leak free piping connection socket integral inverted manhole.

Connection socket integrated inverted manhole of the present invention for achieving the above object, the invert is formed on the bottom surface for the smooth flow of waste water flowing through the inlet and outflow to the drain, the inlet / drain side formed on the side wall In the inverted manhole provided with a connection socket for connection with the inlet, the connection socket for the connection to the pipe on the inlet / drainage side is characterized in that the first inverted manhole is formed integrally with the invert manhole by concrete pouring do.
