Description

Technical Field

[0001] The utility model relates to the technical field of measuring mobile platforms, in particular to a shield tunnel measuring mobile platform. Background Technique

[0002] During the tunnel construction process, surveying and mapping work plays a very important role. In the survey and design stage, topographic surveys must be carried out on the ground to obtain topographic maps for the correct selection of the tunnel location and the design of its geometric shape; during the construction stage, in order to ensure the correct penetration of the opposite excavation faces and the construction of each part according to the design, alignment setting-out surveys must be carried out; during the operation stage, deformation observations of the tunnel itself and the ground nearby are necessary measures to ensure the safety of the tunnel itself and to prevent the ground buildings from being affected. Tunnel surveying first involves control surveys on the ground to determine the relative positions of each entrance. Since tunnels generally pass through mountains or waters and it is difficult to measure distances, the plane control surveys in the past mainly used triangulation methods, supplemented by parallax traverse surveys with transverse base line tapes.
