摘要
The present invention relates to an insertable manhole insertion body, a manhole support member with the same inserted thereinto, and a manufacturing method thereof. First, the insertable manhole insertion body is inserted into an upper manhole support member (an upper plate) into which an upper side of a manhole body is inserted to insert the manhole body, has a ring structure of an n-shaped cross section whose lower side is opened to insert the upper side of the manhole body thereinto, and comprises a main body outer surface contact portion to come in contact with an outer surface of the manhole body, a main body inner surface contact portion to come in contact with an inner surface of the manhole body, and a main body end contact portion to come in contact with an upper end of the manhole body. A gap between the main body outer surface contact portion and the main body inner surface contact portion becomes narrower towards the main body end contact portion to forcibly insert the manhole body. A plurality of insertion body fixing protrusions protrude from an outer surface of the main body end contact portion. A lower side of the main body inner surface contact portion is inserted into an insertable gasket to seal a gap between the inner surface of the manhole body and the main body inner surface contact portion. A manhole support member manufactured by the manufacturing method of a manhole support member which prepares and arranges an insertable manhole insertion body, and the manhole support member with an insertable manhole insertion body inserted thereinto facilitate insertion of a manhole body, improve watertightness, and prevent the manhole insertion body from moving and escaping.
