Prefabricated pipe joint structure for pipe-jacking method tunnel hole opening and using method thereof

The invention discloses a prefabricated pipe joint structure for pipe-jacking method tunnel hole opening and a using method thereof. A hole is formed in the side wall of a pipe joint body, wherein anembedded steel grating plate is arranged in the hole and used for bearing the load of the side wall, where the hole is positioned, of the pipe joint body; an embedded steel plate is arranged on the side wall of the hole and fixed to a stressed steel bar of the pipe joint body through embedded steel plate anchor bars; the embedded steel grating plate comprises an outer frame matched with the hole and a latticed bearing part arranged in the outer frame; and the embedded steel grating plate is detachably connected with the hole in the mode that a plurality of bolts are arranged between the outerframe and the embedded steel plate. During hole opening, the embedded steel grating plate is removed, and a hole pit is excavated; then, a plurality of cast-in-place anchor bars and a plurality of cast-in-place water-stopping
