description | The utility model discloses a prefabricated pipe joint structure for pipe-jacking tunnel holing. Holes are formed in the side wall of a pipe joint body. An embedded steel grating plate is arranged inthe hole and is used for bearing the load of the side wall of the pipe joint main body where the hole is formed; an embedded steel plate is arranged on the side wall of the hole; the pre-buried steelplate is fixed with the stressed steel bars of the pipe joint main body through the pre-buried steel plate anchor bars; the embedded steel grating comprises an outer frame matched with the hole and alatticed bearing part arranged in the outer frame; and the embedded steel grating is detachably connected with the hole in a manner that a plurality of bolts are arranged between the outer frame and the embedded steel plate. During holing, the pre-buried steel grating plate is removed, and a hole pit is excavated; secondly, a plurality of cast-in-place anchor bars and a plurality of cast-in-placewater stop steel plates are |
