Generally, a manhole is installed on the road for maintenance and repair of various underground facilities such as waterworks, sewerage, electricity, and communication.

Such a manhole has been widely used for constructing a manhole through concrete pouring in the field, but it takes a long period of construction such as curing and so on. Due to the disadvantages such as a change in construction quality depending on the season and weather, A prefabricated manhole method in which a plurality of manhole blocks are formed in advance and assembled is often used rather than the manhole construction method.

That is, the prefabricated manhole method is a method of connecting and stacking the manhole block and the manhole block in a state that a plurality of manhole blocks are provided. It is possible to shorten the construction period and to easily adjust the installation height of the manhole, It can provide an advantage that can be achieved.

However, after the manhole block is connected to the manhole block, the manhole block is detached due to side pressure or subsidence, and there is a problem that the sewage or sewage leaks due to the occurrence of a minute gap due to the material separation phenomenon at the connection site.

This may lead to pollution of the environment and weakening of the ground, which is required to be improved, and an efficient method for waterproofing between the manhole block and the manhole block is desperately required.
