[0001] The present invention relates to a manhole capable of adjusting the height of a lid, and more particularly, to a manhole cover for supporting a manhole cover, which has a double structure and can freely elevate and lower the manhole cover to freely adjust the height of the manhole cover. And a method of constructing the manhole.

A manhole is a hole formed on the road surface to enable a person to enter the underground. The place to be installed is installed in the middle of a straight line where the thickness and direction of the pipe are changed, the starting point or crossing point, It is also used for communication.

The shape of a typical manhole is circular with the most ease of construction, and there are also squares and ovals. The entrance is surrounded by a frame made of iron or stone and covered with a circular lid which is made of cast iron or reinforced concrete with a diameter of about 60 cm. The main body is made of concrete or brick, and the inside diameter of the passage hole is often 1 to 1.2 m. The bottom is made to be the same as the bottom of the pipeline, or somewhat down to accommodate the sediment.

On the other hand, conventionally, the installation standard of the manhole cover is such that the height of the top surface of the lid is equal to the height of the ground, and secondly, the state (the top surface of the lid and the ground surface) is always maintained. However, as described above,

The top surface of the lid and the ground were not kept flat due to road construction (mainly overlaying construction) or other reasons (protrusion due to ground settlement, etc.).

Therefore, when the height of the top surface of the manhole cover is different from the height of the manhole cover, a method of closing the manhole or correcting the height of the manhole cover is used to prevent a safety accident.

That is, when the upper surface of the manhole cover is depressed from the ground, the manhole is buried or the height is raised. When the upper surface of the manhole cover protrudes from the ground, the height of the lid is corrected through a separate construction.

However, the conventional method of closing the manhole and the method of correcting the height of the lid as described above have caused enormous economical burdens, and there has also been a problem that the wastewater should be installed again on the water pipe.

In order to solve such a problem, a manhole iron which can vary the height of the manhole cover has been developed. However, since the structure of the manhole iron is very complicated, the production cost is high and the operation is not easy. Can not

Respectively.
