A concrete pipe is provided to save the construction cost by simplifying a process through interconnecting two concrete pipes using non-shrinkage mortar filled between connection grooves. A concrete pipe(100) comprises spigot units(110,110a) at one end thereof and a socket unit(120) at the other end thereof. A first connection groove(112a) is formed on the outer peripheral surfaces of the spigot units. A second connection groove(122) is formed on the inner peripheral surfaces of the socket unit so that the second connection groove faces the first connection groove when the concrete pipe is coupled with spigot units of another concrete pipe. Non-shrinkage mortar(130) is filled between the first and second connection grooves so that the concrete pipe is connected with another concrete pipe. The socket unit is formed with one or more through holes(124).
