A structure for preventing the water leakage of the connecting unit for a concrete socket pipe is provided to prohibit the water leakage of the connecting unit permanently and to remove the cause of the ground subsidence. In a structure for preventing the water leakage of the connecting unit for a concrete socket pipe, a ring-type elastic rubber material is secured to the concrete vertical contact surface of the inside for a socket(30) and the concrete vertical contact surface of the rear end for the connecting unit(40), separately and symmetrically. The two elastic rubber materials(301,401) are compressed when pushing the connecting unit into the socket and deformed in the shape of a square or a diamond.
