PROBLEM TO BE SOLVED: To provide an injection hose including no complex step for manufacturing, spraying an injection agent to all directions and having no direction dependency of strength; and a joining of successive pour method in which an installment of the pouring hose can be easily carried out, the injection agent can be injected efficiently and certainly between a pre-construction concrete and a post-placed concrete and a re-press fitting can be also carried out. SOLUTION: The injection hose comprises a hose body and a cover material and the hose body has a tubular circulation passage for feeding and discharging injection liquid at the inside and a helical groove part at the outside in a longitudinal direction. A plurality of radial apertures for communicating the circulation passage with a groove part are provided in the groove part so as to direct to various directions corresponding to a spiral. The cover material is engaged with the groove part and opens/closes the apertures at the time of feeding and discharging of the injection liquid.
