Embodiment Construction
[0017] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0018] A method for positioning a formwork arch trolley in tunnel construction by a ruler includes the following steps:
[0019] 1) Determine that the traveling mechanism that needs to be positioned by the ruler is the tunnel construction formwork arch trolley;
[0020] 2) In the forward direction of the formwork arch trolley, that is, in the forward direction of the excavation construction tunnel, according to the technological requirements, parallel and symmetrical to the center line of the excavation construction tunnel, determine the parallel position line that needs to be installed with the ruler, and lay out several on the determined position line. Steel piles, use angle steel to fix the steel piles on each side to form a positioning guide for the tunnel construction formwork arch trolley; install calibration contact points on t...
