In particular, the present invention relates to a manhole device and a method of constructing the manhole body which can be constructed without damage to water and sewage pipes and various underground buried materials and to facilitate maintenance work in the manhole body.
In general, the manhole is used to easily maintain or control various underground buried wire wiring devices such as the valve device of water and sewage pipes buried underground or communication cable or power cable. Most of the manholes are made of reinforced concrete bodies. do.
However, these concrete manholes take a long time to cure, which leads to a decrease in productivity. When installing, concrete tools such as hammers and chisels are used on both sides of the floor to fit the diameter of water and sewage pipes and underground works for power and communication. It should be dug up so that water and sewage pipes and underground burial can pass. This type of work varies depending on the skill of the operator, and if the impact is improperly transmitted, cracks may be generated in the concrete body, which shortens the lifespan of the manhole. The cover covering the upper part thereof is made of concrete and the manhole cannot be covered with soil until the cover is cured.

The manhole device of the Republic of Korea Utility Model Registration No. 20-163575 is an arc-shaped passage through which water and sewage pipes and various underground works pass and a manhole is formed in the center and the upper and lower open bodies and the upper part of the body It is composed of a guide that is mounted on the cover having a cover and a manhole cover that can be opened and closed.
The manhole device has a limitation in securing a large internal space that is easy to work with a metal steel plate, and the body and the cover are fastened by bolts, so the fastening state may be released by the load applied by the guide part and the soil. .
In addition, the 'manhole device' of the Republic of Korea Utility Model Registration No. 20-291458 has a manhole body having a passage in the bottom is formed of a metal square, the cover body having a manhole inlet to which the manhole cover is coupled to the upper part of the manhole body integrally It is formed, the cover body has a dome-shaped structure that is curved upward so that the force to withstand external stress is strong.
The manhole device has a wide internal space for work, but since the manhole body is open and the passage is not closed, water is introduced into the manhole device, that is, the inner space of the manhole body, thereby damaging the internal structure or the manhole. It makes the maintenance work in the equipment difficult.
And 'manufactured manhole device' of the Republic of Korea Utility Model No. 20-436633 is a structure that the body can be separated and assembled up and down, the manhole body is cut into the upper part and the lower body by cutting the middle part horizontally and each of these cutting parts The flange is formed so that they can be assembled and detached by bolting, and the guide part formed on the upper body so that the manhole cover is combined is formed to be shorter so that the diameter of the lower part is larger than the diameter of the manhole inlet where the manhole cover is combined as a whole. However, by separating the upper guide portion formed with a lower guide portion and a manhole inlet formed integrally on the upper surface of the upper body, the upper guide portion formed with a manhole inlet to the upper side of the lower guide portion can be assembled and separated.
The manhole device is sealed below the manhole body so that water does not flow from the outside, but in order to allow the water supply pipe or various underground works to pass through the manhole body, the water supply and sewage pipe or various underground works are cut before the manhole device is installed. After installing the manhole device, there is a need to reconnect it.
In addition, in order to move the position of heavy water and sewage pipes and various underground works by using a hoist (hoist) in the manhole device, a fixing ring for fixing the hoist to the ceiling of the manhole device is formed. However, it is difficult to move water and sewage pipes and various underground works by using hoists due to the narrow inner space of the manhole device, and when the maintenance work in the manhole device touches the operator's head, it causes trouble to work. There is.
The present invention for solving the various problems as described above has an object to enable the construction of the manhole device so that the water supply and sewage pipes or underground buried material is located in the manhole device without cutting the water supply and sewage pipes or various underground burial.
In addition, an object of the present invention is to use the hoist to move the location of the water and sewage pipes and various underground buried materials located outside the manhole device, that is, in the manhole device buried underground.
The manhole device according to the present invention for achieving the above object, the manhole body is formed of a metal material, in the manhole device formed with a guide portion having a manhole inlet to which the manhole cover is coupled to the upper part of the manhole body In the bottom surface and side lower part of the manhole body, a lower cut groove and a side cut groove for seating the upper and lower sewer pipes and various underground burials are formed, respectively, In the seated state, a lower closing plate is welded to the lower incision groove, and a side closing plate is welded to the side incision groove, and the fixing flange is welded to the manhole body and the side finishing plate to surround the water and sewage pipe or various underground works. It is fixed, the packing is embedded between the fixing flange and the water and sewage pipe or various underground buried The sealing flange is characterized in that the sealing flange is fastened by bolts.
An inclined surface is formed on one surface of the fixing flange, and a pressing protrusion corresponding to the inclined surface is formed on one surface of the sealing flange.
The fixing flange is integrally welded and fixed to the manhole body before the manhole body is constructed.
The upper part of the manhole body is characterized in that the work hole that can enter the hook (hook) of the hoist (hoist) is formed.
The manhole inlet of the manhole body is characterized in that the ladder descending to the bottom surface of the manhole body is installed.
In addition, the construction method of the manhole device according to the present invention, the first step of installing the manhole body so that the sewage pipe or various underground buried is seated in the lower incision groove and the side incision groove of the manhole body; A second step of welding and sealing a lower closing plate and a side closing plate to the lower cutting groove and the side cutting groove; A third step of welding and fixing a fixing flange to the manhole body and the side finish plate; And a fourth step of putting a packing between the water supply and sewage pipe or various underground installations and the fixing flange, and sealing the bolt by fastening a sealing flange to the fixing flange.
