In general, the manhole is installed underground, and is connected to the water and sewage pipes, electrical and telegraph pipes, transmission pipes and the like. Inside the manhole, valves for water and sewage pipes, booths for electric and telegraphs, and the like are installed. In the conventional manhole, the main material is concrete cement, and the installation process is performed by digging the ground where water, sewage pipes, or electric and telegraph pipes are installed, and then installing the manholes according to the manhole installation. Secure the place of installation. After manufacturing the formwork for concrete, after pouring concrete to form a manhole, connecting the other pipes and connecting the valves and booths, the subsequent piping continues to be installed continuously. The conventional manhole through this process has a problem in that the entire piping construction period is prolonged due to the considerable time required for concrete pouring because it is installed in concrete. In addition, since the manhole is formed by concrete pouring, it is difficult to standardize the concrete. Therefore, a large gap is formed in the joint portion between the conventional manhole and the pipe, so that water, moisture, etc., caused by groundwater or rainwater, seep into the interior of the manhole. do. Such water and moisture easily corrode the inner member of the manhole, and when a considerable amount of water accumulates in the manhole, there is an inconvenience in repairing, replacing and inspecting the inner member, such as watering out before crushing. In particular, when it is necessary to replace an internal member such as a valve or other booth in a manhole, since a large internal member cannot be taken out as the vertical movement passage for the user to move, the upper part of the manhole integrally formed by concrete casting is used. Since it is necessary to take out the inner member to the hole secured by breaking using, unnecessary work is required, and problems such as the upper part of the concrete manhole become poor.

In addition, the waterproof sealed manhole was devised to overcome the above problems, but in the sealed manhole, there is a problem of water accumulation on the floor due to a temperature difference between inside and outside, that is, a condensation problem.

It is installed with a pipe having Preferably stainless steel tubes are preferred.

The first lower part 110 and the first upper part 120 are formed to be integrally coupled to each other in a cylindrical shape, and steel or cast iron may be used as the material. The manhole 10 is formed in a tubular shape, but the flat cross section is formed in a shape suitable for a situation among square, triangular, and polygonal shapes or circular shapes. In addition, since the first upper part 120 and the second lower part 110 of the manhole 10 are made of metal or iron, especially steel or cast iron, the manufacturing process is easy and simple, so that the working process is shortened. . In other words, in the case of using a conventional cement or formed into an irregular shape, even after the manhole construction point is selected, the concrete formwork is formed, and the construction date is again formed by forming a hole for water and sewage or electrical and electronic equipment in the molded outer wall. Although significant, according to the manhole 10 of the present invention, since it is formed of a metal material, it is possible to mass-produce the manhole 10 by standardization, and to shorten the construction date since the installation of the standardized manhole 10 is expected. There is a good point. Accordingly, the first upper part 120 and the first lower part 110 may be manufactured by steel by bending, and also may be manufactured by cast iron by casting, and any one may be produced as a pre-calculated standard product. Since it can be manufactured in various sizes according to the pipe capacity of the water supply and sewage, the size of the installation member for electrical and electronic, etc., the size of the manhole 10 is standardized in various forms so that it can be easily manufactured. In particular, when the first upper part 120 and the first lower part 110 are manufactured by using steel pipes, steel pipes are cut to a suitable length in advance, so the manufacturing process is simple, and the cost required for manufacturing The efficiency of the production can be maximized by reducing the number of days and reducing the time period.
