Method for facilitating core-pulling and pore-forming of precast concrete member

The invention belongs to the technical field of buildings, and relates to a precast concrete member, in particular to a novel core-pulling hole-forming construction method for the precast concrete member. A steel pipe core-pulling method is one of important methods for reserving channels of precast concrete members, and pipe-pulling time is related to cement varieties, air temperature, curing conditions and the like. If the pipe drawing time is too early, the hole channel collapses; and if the pipe drawing time is too late, the concrete is firmly bonded in the steel pipe, and the pipe drawing is difficult and even cannot be drawn out. Therefore, the development of a method for facilitating core-pulling and pore-forming of the precast concrete member has certain necessity. The invention provides a method for facilitating core pulling and hole forming of a precast concrete member. The method is suitable for production of various precast concrete members, the steel pipe does not need to be slowly rotated once ev
