| titleOfInvention | Shield constructs enhancement mosaic structure of section of jurisdiction under closely passing through railway condition |
| abstract | A reinforced splicing structure of shield segments under the condition of passing through a railway at a short distance comprises a plurality of axially spliced shield segment rings and built-in steel rings fixedly supported on the inner peripheries of the shield segment rings; the shield segment ring comprises a plurality of shield segments which are spliced in an annular direction, a plurality of longitudinal bolt hand holes are symmetrically formed in two axial sides of the inner arc surface of each shield segment, a plurality of annular bolt hand holes are formed in two annular sides of the inner arc surface of each shield segment, a plurality of positioning blind holes which radially extend into the shield segments are uniformly distributed in the inner arc surface of each shield segment, and a plurality of through holes which radially penetrate through the shield segments and are provided with internal threads are formed in the middle of each shield segment; a plurality of welding nails are fixedly arranged on the circumferential outer wall of the built-in steel ring, the welding nails are all inserted and fixed in the positioning blind hole of the inner arc surface of the shield segment, the integral strength and rigidity of the lining structure can be increased by the reinforced splicing structure of the shield segment, the durability is good, the anti-cracking performance is good, the deformation is small, the damage to the existing railway is avoided, and the influence on the train operation is avoided. |
