Manhole {A manhole}

The present invention relates to a manhole buried in the ground. More specifically, the present invention relates to a manhole that can be easily and stably fixed to a connecting pipe connected to one side, .

Generally, it is necessary to construct drainage pipes to treat stormwater, wastewater, and sewage in construction works such as civil engineering works, construction works, and road works. In the middle of sewer pipes, inspection, cleaning, ventilation, ventilation, Manholes are installed at regular intervals.

On the other hand, the manhole is installed underground in order to inspect and repair the wiring pipe by installing only a certain section where electric wiring and communication wiring buried in the underground are installed

The manhole is formed of a cylindrical concrete structure, and the inlet pipe and the outlet pipe through which the sewage or the like flows into or out of the manhole are inserted and connected to the connection hole formed in the wall of the manhole.

As the inflow pipe and the outflow pipe, a corrugated pipe having irregularities on the surface is used.

Such a manhole is usually used as a manhole of a cast-in-place concrete as in Korean Patent No. 1171870. However, the disadvantage of a manhole placed on the site is that the construction period is prolonged, the construction cost is increased, The quality of the product, difficulty in securing skilled workers, increase in complaints, difficulty in completely blocking the leakage, difficulty in adjusting the height, and the like.
