| description | The utility model discloses a U-shaped groove structure of a fabricated open-cut shallow-buried tunnel, which is applied to the field of fabricated buildings and comprises a first prefabricated part. Due to the adoption of the rib plate type structure, the self weight of the structure is greatly reduced, the concrete consumption is reduced, the division length of the longitudinal sections is increased, the number of the sections is reduced, transportation and hoisting are facilitated, the manufacturing cost is saved, and the rib plate type reinforced concrete structure is adopted for the small-stress part of the structure; after a U-shaped groove is installed, a supporting rod is installed in a fixing mechanism, a rotating head is rotated, the rotating head rotates to drive a first screw to rotate, the first screw rotates to drive a sliding block to move, and the sliding block moves to drive the supporting rod to move. And the supporting rod moves to support and reinforce the inner wall of the U-shaped groove |
