PROBLEM TO BE SOLVED: To enable long-distance slurry curved pipe jacking even in the case of a small-diameter pipe. SOLUTION: This small-diameter pipe slurry curved pipe jacking apparatus 1 includes a connecting body 8 which includes: a casing 2; a sludge sending pipe 3 and a sludge removal pipe 4, fixed in the axial direction of the casing 2; a connecting block 5 fixed to an end of the casing 2 and provided with mounting holes 50 and 51 for mounting the sludge sending pipe 3 and the sludge removal pipe 4, respectively; a rail 6 fixed in the axial direction of the casing 2; and a holding member 80 provided in the casing 2 so as to maintain an interval between the small-diameter pipe 7 and the casing 2. The small-diameter pipe slurry curved pipe jacking apparatus 1 also includes a camera 9 which takes an image in the longitudinal direction of pipe jacking, a target 10 which is provided near the camera 9, and a camera carrier 11 for integrally fixing the camera 9 and the target 10 together.
