Two -dimentional chi is measured to immersed tube tunnel tube coupling

The utility model relates to an immersed tube tunnel construction technical field discloses a two -dimentional chi is measured to immersed tube tunnel tube coupling. This two -dimentional chi is measured to immersed tube tunnel tube coupling includes: transverse ruler, perpendicular chi and base, erect the chi set up perpendicularly in on the base, the transverse ruler perpendicular to erect the chi setting, and can follow erect the axial displacement of chi, transverse ruler can also follow base axial displacement, transverse ruler include a transverse ruler and set up in the 2nd transverse ruler of transverse ruler bottom, a transverse ruler's scale and the 2nd transverse ruler's scale set up opposite direction. The utility model provides an adopting among the two -dimentional chi is measured to immersed tube tunnel tube coupling and measuring horizontal spacing and the longitudinal separation between leading truck and the guide arm, simple structure just can measure through the adjustment of the smooth saddle of measuring tape, have convenient to use, range of application advantage extensively.
