<p>The present invention relates to a prefabricated tee pipe for preventing the cutoff of water, wherein an upper tee pipe, a lower tee pipe and a flange pipe for plugging are cast respectively, and the flange pipe for plugging having an accommodation groove formed on an inner circumference surface is combined with the branching device of the upper tee pipe using a bolt. The prefabricated tee pipe for preventing the cutoff of water according to the present invention comprises: an upper tee pipe (10), a lower tee pipe (20) and a flange pipe for plugging (30), which are cast respectively, wherein the side flange part (11) of the upper tee pipe (10) and the side flange part (21) of the lower tee pipe (20) are combined with each other using a plurality of combining bolts; a branching device (12) formed in the middle of the upper tee pipe (10), wherein the lower end of the pipe part (31) of the flange pipe for plugging (30) is mounted on the upper surface (12a) of the branching device; a plurality of coupling parts (13) installed at regular intervals around the branching device (12); a flange part (32) integrally formed around the upper end of the pipe part (31); a plurality of first bolt holes (33) formed on the flange part (32); first bolts (50) coupled to the coupling holes (13a) of the coupling parts (13) through the first bolt holes (33); and second bolt holes (34) formed on the flange part (32), wherein the second bolt holes (34) are arranged at both side parts of the first bolt holes (33) and an accommodation groove (35) is formed on the inner circumference surface of the pipe part (31).</p> |
