The invention relates to the technical field of ejection pipes of non-excavation works, in particular to a reinforced concrete ejection pipe joint connector. The connector is positioned at a connection between a front pipe joint and a rear pipe joint which are adjacent. The connection part of the connector at least comprises a pipe joint outer wall sealing connecting part and a pipe joint inner wall sealing connecting part. The pipe joint outer wall sealing connecting part at least comprises a socket steel bushing ring positioned at the rear end of the front pipe joint and a socket steel ringpositioned at the front end of the rear pipe joint. The pipe joint inner wall sealing connecting part at least comprises the structure that steel bushing rings separately arranged on the front pipe joint inner wall and the rear pipe joint inner wall. Each steel bushing ring at least comprises an annular steel ring and an annular slab. Ribbed plates and bolted holes are uniformly distributed on thefront side and the rear side of the slab. The ribbed plate and the bolted holes are staggered mutually in position. The bolted holes in the front pipe joint slab are corresponding to those of the rear pipe joint slab. The bolted holes corresponding to one another are connected by bolts and nuts. The pipe joint connector adopting the technical scheme can completely meet the need of projects with high waterproof requirements, and can adapt to complex construction environments such as high water pressure and soft ground.
