Segment structure for preventing jamming at position of transverse channel of subway and construction method of segment structure

The invention relates to a duct piece structure for preventing jamming at a subway transverse passage position and a construction method thereof, and belongs to the technical field of shield duct pieces, the duct piece structure comprises a non-holed area duct piece and a holed area duct piece, a holed area non-cutting part and a holed area cutting part are integrally cast and formed, the construction steps and the construction period are reduced, and the construction efficiency is improved. And the connection quality of the joint of the non-cutting part and the cutting part is ensured. The non-cutting part of the holing area is a steel structure aramid fiber concrete pipe piece, the cutting part of the holing area is an aramid fiber concrete pipe piece, and the glass fiber reinforced concrete pipe piece is replaced with the aramid fiber concrete pipe piece, so that the structure at the position of the connecting channel portal can meet the stress requirement during main tunnel construction, and the construct
