Pipeline protection reserved hole template

The utility model belongs to the field of constructional engineering, and particularly relates to a pipeline protection reserved hole template which comprises a pipeline protection embedded cylinder used for embedding, a pipeline protection cavity used for containing a pipeline and a cable is formed in the pipeline protection embedded cylinder, and a sponge cylinder is arranged on the inner wall of the pipeline protection cavity. The side face formworks are installed at the front end and the rear end of the pipeline protection pre-buried barrel, the pipeline protection pre-buried barrel is arranged between the two side face formworks, and the pipeline protection pre-buried barrel can be pre-buried in a poured concrete building and can wrap and protect a pipeline and a cable penetrating through a pipeline protection cavity. The two pipeline protection embedded cylinders embedded in concrete form a reserved hole through the arranged pipeline protection cavities, the pipeline protection cavities of the two pipel
