The beneficial effects of the utility model are:
Measurement duct pieces of shield tunnel axial rotating device provided by the utility model is based on hanging down by circular arc string center
The line geometrical principle vertical with circular arc is designed, i.e., the measurement main scale middle line on tunnel vault section of jurisdiction is sticked on by level
Vertical line, be the theoretical axis of section of jurisdiction, specifically, find tunnel vault section of jurisdiction center bolt hole position, the position and tunnel
The line in the road center of circle is the practical axis of section of jurisdiction, and is drawn directly on tunnel vault section of jurisdiction along the direction perpendicular to tunnel cross section
Line is as mark line；Then auxiliary scale is sticked on tunnel vault section of jurisdiction, and the end of auxiliary scale is placed in former and later two pipes
The intersection of piece or the distance equal apart from the intersection, so that measurement main scale is parallel with tunnel cross section, rotation measuring main scale
For bubble to zero-bit, bubble center and the line in the tunnel center of circle are the theoretical axis of section of jurisdiction, slide movement in water column on to level meter
Scale makes its alignment mark line, and reading of the mobile scale on measurement main scale is the practical axial rotation amount in section of jurisdiction (on the left side of " 0 "
Side is negative value, is positive value on the right side of " 0 ").Section of jurisdiction axial-rotation amount can be received in time by the device, feed back to pipe sheet assembling
Manipulator adjusts, corrects.The apparatus structure is simple, ingenious in design, cost of manufacture is cheap, execute-in-place is flexible, quick, nothing
Need fine measuring instrument conjunction measuring.
