In the case of a manhole manufactured and installed in such a single piece, the larger the size of the manhole frame, the greater the bending In this process, when the vehicle is stepped on or passed by, or when heavy items are stepped on, the noise caused by the shaking is caused.Then, the lid and the frame are fixed by using bolts or nuts to prevent the shaking. This was accompanied by a problem such as the need for a mechanism to loosen and tighten the nut or bolt and the excessive time, and also the appearance of neat appearance.

In addition, in the case of manhole frames, when manufacturing a manhole frame, one or more manhole frames could not be produced in a single mold of the same size, and in order to manufacture a large number of manhole frames, the number of molds had to be increased to increase the production cost. . Accordingly, when the work is performed using the existing single mold, the working time is long and the working efficiency of the worker is reduced, thereby reducing the productivity as well as the efficiency.

In addition, when the manhole and the frame is manufactured integrally, the weight is increased and increased during transportation, transportation, and storage, as well as there is a problem in space utilization.
