Description
technical field [0001] The invention relates to a measuring instrument and method for trackless construction of a catenary in a tunnel and belongs to the technical field of tunnel engineering measurement. Background technique [0002] Rail transit is a very extensive system. Rail transit includes ordinary railways, subways, and local railways. Nowadays, rail transit has fully developed into traction power supply. When constructing in rail transit tunnels, it is often faced with lagging civil engineering and track laying construction, which severely suppresses the construction of units behind the station, and multiple units cross construction, which greatly increases the difficulty of catenary construction. In order to ensure the progress of the construction period, the catenary professional needs to carry out installation work before the track-laying unit enters the site. The difficulty of trackless construction is obvious. In order to ensure the quality, it is particularly...
